Anemia means your blood does not carry enough oxygen to meet your body's needs. Red blood cells contain hemoglobin — the protein that picks up oxygen in the lungs and delivers it to every organ. When hemoglobin falls too low, every organ suffers — especially the heart (which works harder) and the kidneys (which need oxygen to maintain filtration).Ang anemia ay nangangahulugang ang inyong dugo ay hindi nagdadala ng sapat na oxygen para matugunan ang pangangailangan ng katawan. Ang mga pulang selula ng dugo ay naglalaman ng hemoglobin — ang protina na kumukuha ng oxygen sa baga at naghahatid nito sa bawat organo. Kapag masyadong bumaba ang hemoglobin, nagdurusa ang bawat organo — lalo na ang puso (na nagtatrabaho nang mas malakas) at ang mga bato (na nangangailangan ng oxygen upang mapanatili ang pagsasala).Ang anemia nagpasabot nga ang inyong dugo dili magdala og igo nga oxygen aron matubag ang mga pangangailangan sa lawas. Ang mga pulang selula sa dugo adunay hemoglobin — ang protina nga mokuha og oxygen sa baga ug maghatod niini sa matag organo. Kon mubaba kaayo ang hemoglobin, mag-antos ang matag organo — ilabi na ang kasingkasing (nga nagbuhat og mas kusog) ug ang mga kidney (nga nanginahanglan og oxygen aron mapadayon ang pagsala). Ing anemia ya nangangahulugang ing inyu daya ya ali nagdadala ning sapat a oxygen para matugunan ing pangangailangan ning bangkî. Ing deng pulang selula ning daya ya naglalaman ning hemoglobin — ing protina a kumukuha ning oxygen king baga at naghahatid nini king bawat organo. Nung masyadong bumaba ing hemoglobin, nagdurusa ing bawat organo — lalo a ing pusu (a nagtatrabaho nang mas malakas) at ing deng batu (a nangangailangan ning oxygen upang mapanatili ing pagsasala).

In adults, anemia means hemoglobin (Hb) below 13 g/dL in men or 12 g/dL in women. Children need age-specific criteria. Diagnosis is separate from the treatment goal: adults taking an ESA should have an individualized Hb goal below 11.5 g/dL. Children require individualized specialist targets.

Sa adult, anemia ang hemoglobin (Hb) na mas mababa sa 13 g/dL sa lalaki o 12 g/dL sa babae. Sa bata, ayon sa edad ang pamantayan. Magkaiba ang diagnosis at layunin ng paggamot: sa adult na naka-ESA, indibidwal ang layunin at mas mababa sa 11.5 g/dL. Kailangan ng espesyalistang magtakda ng layunin para sa bata.

Sa hamtong, anemia ang hemoglobin (Hb) nga ubos sa 13 g/dL sa lalaki o 12 g/dL sa babaye. Sa bata, ang sukdanan nagdepende sa edad. Lahi ang diagnosis ug tumong sa pagtambal: sa hamtong nga nag-ESA, ipahaom ang tumong ug ipabilin nga ubos sa 11.5 g/dL. Ang espesyalista motakda sa tumong sa bata.

Why CKD causes anemia — four mechanisms: EPO deficiency, hepcidin-mediated iron restriction, uremic toxin-shortened RBC lifespan, and PTH-driven marrow fibrosis

This illustration shows the four main reasons damaged kidneys lead to anemia: too little EPO (erythropoietin) hormone, iron locked away by hepcidin, red blood cells that wear out faster, and bone marrow that makes fewer cells.

CKD anemia is multifactorial — EPO deficiency, iron-restricted erythropoiesis, and shortened RBC (red blood cell) survival all contribute simultaneously. All three must be addressed.Ang anemia sa CKD ay may maraming dahilan — ang kakulangan ng EPO, ang iron-restricted erythropoiesis, at ang pinaikling buhay ng RBC ay sabay-sabay na nag-aambag. Ang lahat ng tatlo ay dapat tugunan.Ang anemia sa CKD adunay daghang hinungdan — ang kakulang sa EPO, ang iron-restricted erythropoiesis, ug ang gipamubo nga kinabuhi sa RBC nagambibit tanan sa dungan.

The heart compensates for anemia by beating faster and pumping more blood — chronic compensation causes left ventricular hypertrophy and eventual heart failure. In dialysis patients, anemia is independently associated with increased cardiovascular mortality, hospitalizations, and reduced quality of life.Ang puso ay nagbabayad para sa anemia sa pamamagitan ng mas mabilis na pagtibok at pagpump ng mas maraming dugo — ang patuloy na pagbabayad ay nagdudulot ng left ventricular hypertrophy at kalaunan ay pagpalya ng puso.

In a CKD or dialysis patient, anemia is rarely from a single cause. The most common combination is EPO deficiency + iron deficiency + chronic inflammation — all three must be addressed simultaneously. Treating EPO deficiency alone without ensuring iron adequacy is a common cause of ESA (erythropoiesis-stimulating agent) therapy failure.Sa isang pasyenteng may CKD o nasa dialysis, ang anemia ay bihirang manggaling sa isang dahilan lamang. Ang pinakakaraniwang kombinasyon ay kakulangan ng EPO + kakulangan ng iron + kronikong pamamaga — ang lahat ng tatlo ay dapat tugunan nang sabay-sabay. Ang paggamot lamang sa kakulangan ng EPO nang hindi tinitiyak ang sapat na iron ay isang karaniwang sanhi ng pagkabigo ng ESA therapy.Sa usa ka pasyente nga may CKD o nag-dialysis, ang anemia panagsa ra gikan sa usa ka hinungdan lamang.

The peritubular cells of the kidney sense oxygen tension and produce erythropoietin in response to hypoxia. As kidney tissue is lost in CKD, EPO production falls proportionally. Without EPO, the bone marrow receives no signal to produce new red blood cells — existing cells age and die without replacement, causing progressive anemia.Ang mga peritubular cell ng bato ay nakakakita ng oxygen tension at gumagawa ng erythropoietin bilang tugon sa hypoxia. Habang nawawala ang tissue ng bato sa CKD, ang produksyon ng EPO ay bumababa nang proporsyonal. Nang wala ang EPO, ang bone marrow ay walang natatanggap na senyal para gumawa ng bagong mga pulang selula ng dugo — ang mga kasalukuyang selula ay tumatanda at namamatay nang walang kapalit, na nagdudulot ng progresibong anemia.Ang mga peritubular cell sa kidney nakabati sa oxygen tension ug nagpatunghag erythropoietin isip tubag sa hypoxia.

Iron deficiency — absolute and functionalKakulangan ng iron — ganap at functionalKakulang sa iron — absoluto ug functional Kakulangan ning iron — ganap at functional

CKD patients lose iron through the dialysis circuit (blood remaining in tubing), frequent blood draws, and GI bleeding from uremic platelet dysfunction. Additionally, inflammation raises hepcidin — a hormone that blocks iron release from stores even when ferritin appears adequate. This pattern is called iron-restricted erythropoiesis (not enough iron reaching the marrow despite apparently adequate stores). In hemodialysis it often responds better to IV iron; in non-dialysis CKD, oral or IV iron can both be reasonable and the choice is individualized. Note that a rise in hemoglobin after IV iron does not by itself prove iron deficiency.Ang mga pasyenteng may CKD ay nawawalan ng iron sa pamamagitan ng dialysis circuit (dugo na nananatili sa tubing), madalas na pagkuha ng dugo, at GI bleeding mula sa uremic platelet dysfunction. Bukod dito, ang pamamaga ay nagpapataas ng hepcidin — isang hormon na humahadlang sa pagpapalabas ng iron mula sa mga imbakan kahit na tila sapat ang ferritin. Ang pattern na ito ay tinatawag na iron-restricted erythropoiesis (kulang ang iron na umaabot sa marrow kahit tila sapat ang imbak). Sa hemodialysis, madalas itong mas tumutugon sa IV iron; sa non-dialysis CKD, maaaring parehong makatwiran ang oral o IV iron at isinasapersonal ang pagpili. Tandaan: ang pagtaas ng hemoglobin pagkatapos ng IV iron ay hindi nagpapatunay mag-isa ng kakulangan sa iron.Ang mga pasyente nga may CKD nawad-an og iron pinaagi sa dialysis circuit (dugo nga nagpabilin sa tubing), kanunay nga pagkuha sa dugo, ug GI bleeding gikan sa uremic platelet dysfunction. Dugang pa, ang pamamaga nagpataas sa hepcidin — usa ka hormon nga nagpugong sa pagpagawas sa iron gikan sa mga imbakan bisan kung tila sapat ang ferritin. Kini nga pattern gitawag nga iron-restricted erythropoiesis (kulang ang iron nga moabot sa marrow bisan pa og tila igo ang stores). Sa hemodialysis, kasagaran mas motubag kini sa IV iron; sa non-dialysis CKD, mahimong pareho nga makatarunganon ang oral o IV iron ug ang pagpili gipahiangay sa tawo.

Uremic toxins damage red blood cell membranes, shortening their lifespan from the normal 120 days to as little as 60–90 days. Even with adequate EPO and iron, the bone marrow cannot produce cells fast enough to replace those being destroyed — worsening the anemia.Ang mga uremic toxin ay nagpapasama ng mga lamad ng pulang selula ng dugo, pinaikli ang kanilang buhay mula sa normal na 120 araw hanggang 60–90 araw lamang. Kahit may sapat na EPO at iron, ang bone marrow ay hindi makapaggawa ng mga selula nang mabilis upang mapalitan ang mga nasisira — nagpapalubha ng anemia.Ang mga uremic toxin nagdaot sa mga lamad sa pulang selula sa dugo, gipamubo ang ilang kinabuhi gikan sa normal nga 120 ka adlaw ngadto sa 60–90 ka adlaw lamang.

Severely elevated PTH (parathyroid hormone) causes marrow fibrosis (osteitis fibrosa cystica) — replacing the normal marrow where red cells are made with fibrous tissue. This form of anemia responds poorly to EPO and iron — it requires control of PTH through active vitamin D, phosphate binders, and sometimes parathyroidectomy.Ang matinding pagtaas ng PTH ay nagdudulot ng marrow fibrosis (osteitis fibrosa cystica) — pinapalitan ang normal na marrow kung saan ginagawa ang mga pulang selula ng fibrous tissue.

Systemic iron deficiency means both circulating iron AND stored iron are low. Iron-restricted erythropoiesis means there is not enough circulating iron reaching the marrow despite apparently adequate stores — driven by inflammation and hepcidin, and by ESA-driven iron use. Ferritin and TSAT are the two markers used to tell these apart. They are imperfect (ferritin also rises with inflammation) but remain the principal trial-tested measures. Importantly, a rise in hemoglobin after IV iron does not by itself prove that iron deficiency was the problem.Ang systemic iron deficiency ay nangangahulugang mababa ang parehong umiikot (circulating) na iron AT nakaimbak na iron. Ang iron-restricted erythropoiesis ay nangangahulugang kulang ang umiikot na iron na umaabot sa marrow kahit tila sapat ang imbak — dulot ng pamamaga at hepcidin, at ng paggamit ng iron dahil sa ESA. Ang ferritin at TSAT ang dalawang marker na ginagamit upang pag-ibahin ang mga ito. Hindi sila perpekto (tumataas din ang ferritin sa pamamaga) ngunit nananatiling pangunahing sinubok-sa-pananaliksik na sukatan. Mahalaga: ang pagtaas ng hemoglobin pagkatapos ng IV iron ay hindi nagpapatunay mag-isa na kakulangan sa iron ang problema.Ang systemic iron deficiency nagpasabot nga ubos ang circulating iron UG stored iron. Ang iron-restricted erythropoiesis nagpasabot nga kulang ang circulating iron nga moabot sa marrow bisan tuod og tila igo ang stores — tungod sa pamamaga ug hepcidin, ug sa paggamit sa iron tungod sa ESA. Ang ferritin ug TSAT ang duha ka marker nga gigamit aron mailhan kini. Dili sila hingpit (ang ferritin mosaka usab sa pamamaga) apan nagpabilin nga panguna nga na-trial nga sukdanan. Importante: ang pagsaka sa hemoglobin human sa IV iron dili magpamatuod nga mag-inusara nga kakulang sa iron ang problema. Ing systemic iron deficiency ya buri nang sabian mababa ing parehong circulating a iron AT nakaimbak a iron.

Oral iron — overviewOral iron — pangkalahatang-ideyaOral iron — kinatibuk-an Oral iron — pangkalahatang-ideya

Oral iron remains the first-line choice for pre-dialysis CKD Stage 1–3 with mild-to-moderate iron deficiency. Absorption is limited in CKD (hepcidin elevation, reduced gastric acid) — typically only 10–15% of the elemental iron dose is absorbed, compared to 25–35% in healthy individuals. Multiple formulations are now available in the Philippines with different elemental iron content, tolerability profiles, and mechanisms of absorption. See comparison table below.Ang oral iron ay nananatiling pangunahing pagpipilian para sa pre-dialysis CKD Stage 1–3 na may banayad hanggang katamtamang kakulangan ng iron. Ang pagsipsip ay limitado sa CKD (pagtaas ng hepcidin, nabawasang gastric acid) — karaniwang 10–15% lamang ng elemental iron dose ang nasipsip, kumpara sa 25–35% sa mga malusog na tao. Maraming formulation ang available na sa Pilipinas na may iba't ibang nilalaman ng elemental iron, profile ng tolerability, at mekanismo ng pagsipsip. Tingnan ang talahanayan ng paghahambing sa ibaba.Ang oral iron nagpabilin nga pangunahing kapilian alang sa pre-dialysis CKD Stage 1–3 nga adunay banayad hangtod katamtamang kakulang sa iron. Ang pagsuyop limitado sa CKD (pagtaas sa hepcidin, nabuwang gastric acid) — kasagarang 10–15% lamang sa elemental iron dose ang nasuyop, kumpara sa 25–35% sa mga malusog nga tawo. Daghang formulation ang available na sa Pilipinas nga adunay lain-laing sulod sa elemental iron, profile sa tolerability, ug mekanismo sa pagsuyop. Tan-awa ang talahanayan sa pagtandi sa ubos.

IV iron — preferred in hemodialysis; an option in other CKDIV iron — mas pinipili sa hemodialysis; isang opsyon sa ibang CKDIV iron — gipalabi sa hemodialysis; usa ka kapilian sa ubang CKD IV iron — mas pipilinan king hemodialysis; metung a opsyon king aliwa pang CKD

IV iron sucrose is the standard in Philippine dialysis centers, available locally as Ferrofer, Anema, and Ferriscript (all iron sucrose 100 mg/5 mL ampoules — available at Philippine dialysis centers). All are iron sucrose complex formulations and are clinically equivalent for standard dosing. IV iron bypasses absorption barriers and delivers iron directly to storage and bone marrow. In in-center hemodialysis it is generally preferred over oral iron; in non-dialysis CKD it is one option among several and is not automatically superior to a trial of oral iron. In hemodialysis (HD) it is commonly given as 100 mg per session, up to 10 sessions to replace a deficit, then as a scheduled maintenance dose set by your unit and adjusted to your iron tests. Infuse slowly over 15–30 minutes diluted in 100 mL normal saline. Monitor for hypersensitivity reactions — observe patient for 30 minutes post-infusion. Per KDIGO 2026, withhold iron when ferritin >700 ng/mL or TSAT ≥40%, and temporarily suspend IV iron during active systemic infection (ferritin is also falsely raised by inflammation).Ang IV iron sucrose ang karaniwang ginagamit sa mga dialysis center sa Pilipinas, available nang lokal bilang Ferrofer, Anema, at Ferriscript (lahat ay iron sucrose 100 mg/5 mL ampoule). Lahat ay naglalaman ng iron sucrose complex at clinically equivalent para sa karaniwang dosis. Ang IV iron ay lumalampas sa mga hadlang sa pagsipsip at naghahatid ng iron nang direkta sa imbakan at bone marrow. Sa in-center hemodialysis, karaniwang mas pinipili kaysa oral iron; sa non-dialysis CKD ito ay isa lamang sa mga opsyon at hindi awtomatikong mas mahusay kaysa subok ng oral iron. Sa HD, karaniwang ibinibigay ito bilang 100 mg bawat session, hanggang 10 session upang punan ang kakulangan, at pagkatapos ay isang nakatakdang maintenance na dosis na itinatakda ng inyong unit at inaayon sa iyong iron tests. Mag-infuse nang dahan-dahan sa loob ng 15–30 minuto na natunaw sa 100 mL normal saline. Bantayan ang mga reaksyon ng hypersensitivity — obserbahan ang pasyente sa loob ng 30 minuto pagkatapos ng infusion. Ayon sa KDIGO 2026, pigilan ang iron kapag ferritin >700 ng/mL o TSAT ≥40%, at pansamantalang ihinto ang IV iron sa panahon ng aktibong systemic infection (mataas din nang mali ang ferritin dahil sa pamamaga).Ang IV iron sucrose kasagarang gigamit sa mga dialysis center sa Pilipinas, available nang lokal isip Ferrofer, Anema, ug Ferriscript (tanan iron sucrose 100 mg/5 mL ampoule). Tanan adunay iron sucrose complex ug clinically equivalent alang sa standard nga dosis. Ang IV iron milabang sa mga babag sa pagsuyop ug naghatod sa iron direkta sa imbakan ug bone marrow. Sa in-center hemodialysis sagad gipalabi kaysa oral iron; sa non-dialysis CKD kini usa lamang ka kapilian ug dili awtomatikong mas maayo kaysa pagsulay sa oral iron. Sa HD, kasagaran kini ihatag isip 100 mg matag session, hangtod 10 ka session aron pun-on ang kakulang, unya usa ka naka-iskedyul nga maintenance nga dosis nga gitakda sa inyong unit ug gipahaom sa imong iron tests. Mag-infuse nga hinay sulod sa 15–30 minuto nga natunaw sa 100 mL normal saline. Bantayan ang mga reaksyon sa hypersensitivity — obserbahan ang pasyente sulod sa 30 minuto human sa infusion. Sumala sa KDIGO 2026, pugngan ang iron kon ferritin >700 ng/mL o TSAT ≥40%, ug temporaryong ihunong ang IV iron sa panahon sa aktibong systemic infection (ang ferritin sayop usab nga mosaka tungod sa pamamaga).

Not all oral iron supplements are equal. Conventional ferrous sulfate is inexpensive but poorly tolerated and poorly absorbed in CKD. Newer formulations — sucrosomial iron (Sideral) and liposomal/ferric pyrophosphate (Pelamis) — offer higher bioavailability, significantly fewer GI side effects, and novel absorption pathways that partially bypass hepcidin blockade.Hindi lahat ng oral iron supplement ay pantay. Ang conventional ferrous sulfate ay mura ngunit mahirap tiisin at mahirap masipsip sa CKD. Ang mga bagong formulation — sucrosomial iron (Sideral) at liposomal/ferric pyrophosphate (Pelamis) — ay nag-aalok ng mas mataas na bioavailability, mas kaunting GI side effects, at mga bagong landas ng pagsipsip na bahagyang lumalampas sa hepcidin blockade.Dili tanan nga oral iron supplement managsama.

KDIGO 2026 adult anemia esa reference; see the text below for criteria

KDIGO 2026 guidance for adult CKD anemia. Clinical decisions are individualized; the text below gives the criteria and limitations.

CKD
Chronic kidney disease
Hb
Hemoglobin
ESA
Erythropoiesis-stimulating agent
TSAT
Transferrin saturation

Before starting an ESA, reversible causes are corrected first — iron deficiency, infection or inflammation, B12/folate deficiency, and blood loss. When those are addressed and hemoglobin is still low, erythropoiesis-stimulating agents (ESAs) may be considered. There is no single hemoglobin number that triggers ESA in every population; the decision is individualized (symptoms, how fast hemoglobin is falling, wish to avoid transfusion, transplant candidacy, and risks such as cancer, stroke, or clots) and made through shared decision-making with your nephrologist. The goal is to use the lowest effective dose to relieve symptoms and reduce the need for transfusion — not to normalize hemoglobin.Bago simulan ang ESA, unang itinatama ang mga nababawi na sanhi — kakulangan sa iron, impeksyon o pamamaga, kakulangan sa B12/folate, at pagkawala ng dugo. Kapag natugunan ang mga ito at mababa pa rin ang hemoglobin, maaaring isaalang-alang ang erythropoiesis-stimulating agents (ESA). Walang iisang numero ng hemoglobin na nagsisimula ng ESA sa bawat populasyon; isinasapersonal ang desisyon (sintomas, bilis ng pagbaba ng hemoglobin, hangaring iwasan ang transfusion, pagiging kandidato sa transplant, at mga panganib tulad ng kanser, stroke, o pamumuo) sa pamamagitan ng shared decision-making kasama ang inyong nephrologist. Layunin ang pinakamababang epektibong dosis upang mapawi ang sintomas at bawasan ang pangangailangan sa transfusion — hindi ang gawing normal ang hemoglobin.Sa dili pa magsugod og ESA, unahon pagtul-id ang mga mabalik nga hinungdan — kakulang sa iron, impeksyon o pamamaga, kakulang sa B12/folate, ug pagkawala sa dugo. Kon masulbad kini ug ubos gihapon ang hemoglobin, mahimong konsiderahon ang erythropoiesis-stimulating agents (ESA). Walay usa ka numero sa hemoglobin nga magsugod og ESA sa matag populasyon; ang desisyon gipahiangay (sintomas, kakusog sa pag-ubos sa hemoglobin, tinguha nga malikayan ang transfusion, pagka-kandidato sa transplant, ug mga peligro sama sa kanser, stroke, o pamuo) pinaagi sa shared decision-making uban sa inyong nephrologist. Ang tumong mao ang paggamit sa labing ubos nga epektibong dosis aron mahupay ang sintomas ug makunhod ang panginahanglan sa transfusion — dili aron himoong normal ang hemoglobin. Bayu simulan ing ESA, mumuna metatama ing deng mababawi a sanhi — kakulangan king iron, impeksyon o pamamaga, kakulangan king B12/folate, at pangawala ning daya. Nung metugunan ne deti at mababa pamu ing hemoglobin, malyaring isaalang-alang ing erythropoiesis-stimulating agents (ESA). Alang metung a numeru ning hemoglobin a magsimula ning ESA king balang populasyon; me-personalize ing desisyon (sintomas, bilis ning pamababa ning hemoglobin, kaburian a iwasan ing transfusion, pamagkandidato king transplant, at deng panganib anti ing kanser, stroke, o pamumu) king pamamagitan ning shared decision-making kayabe ing inyu nephrologist. Ing layunin ya gamitan ing pekamababang epektibong dosis para mapawi ing sintomas at bawasan ing pangangailangan king transfusion — ali ing gawang normal ing hemoglobin.

Iron first — alwaysIron muna — palagiIron una — kanunay Iron muna — palagi

ESA therapy without adequate iron stores is ineffective and wasteful — the bone marrow needs iron to build hemoglobin in every new red cell. So iron status should be assessed and optimized before starting or increasing an ESA. The exact ferritin and TSAT figures used differ by population (hemodialysis units are managed differently from non-dialysis CKD), so treat them as thresholds to interpret with your nephrologist, not as fixed automatic orders.Ang ESA therapy nang walang sapat na imbakan ng iron ay hindi epektibo at sayang — kailangan ng bone marrow ang iron upang bumuo ng hemoglobin sa bawat bagong pulang selula. Kaya dapat suriin at i-optimize ang katayuan ng iron bago simulan o taasan ang ESA. Naiiba ang eksaktong bilang ng ferritin at TSAT ayon sa populasyon (magkaiba ang pamamahala sa hemodialysis at sa non-dialysis CKD), kaya ituring ang mga ito bilang threshold na binibigyang-kahulugan kasama ang inyong nephrologist, hindi bilang nakapirming awtomatikong utos.Ang ESA therapy nga walay igo nga imbakan sa iron dili epektibo ug sayang — ang bone marrow nanginahanglan og iron aron magtukod og hemoglobin sa matag bag-ong pulang selula. Busa kinahanglan susihon ug i-optimize ang kahimtang sa iron sa dili pa magsugod o magdugang sa ESA. Lahi ang eksaktong numero sa ferritin ug TSAT matag populasyon (lahi ang pagdumala sa hemodialysis ug sa non-dialysis CKD), busa isipa kini nga mga threshold nga hubaron uban sa inyong nephrologist, dili nga pihong awtomatikong mando. Ing ESA therapy nang alang sapat a imbakan ning iron ya ali epektibo at sayang — kailangan ning bone marrow ing iron para bumuo ning hemoglobin king balang bagong pulang selula. Kaya dapat suriin at i-optimize ing katayuan ning iron bayu simulan o taasan ing ESA. Miyayaliwa ing eksaktong bilang ning ferritin at TSAT base king populasyon (miyayaliwa ing pamamahala king hemodialysis at king non-dialysis CKD), kaya ituring la deti bilang threshold a bibiyang-kahulugan kayabe ing inyu nephrologist, ali bilang nakapirming awtomatikong utos.

Starting dose and routePanimulang dosis at rutaSinugdanan nga dosis ug ruta Panimulang dosis at ruta

Epoetin alfa — available in the Philippines as Eprex (Janssen) and Eposino (Goodfellow) — is the standard first-line ESA. Dose: 4,000 IU subcutaneously 2–3 times per week (or IV during dialysis). Recormon (Roche) is epoetin beta — a distinct molecular form available in 2,000 IU, 5,000 IU, and 10,000 IU prefilled syringes — and is also used in the Philippines but is not epoetin alfa. Both alpha and beta forms stimulate the same EPO receptor and have comparable clinical efficacy at equivalent doses; however they are not interchangeable unit-for-unit — confirm the specific agent and dose with your nephrologist. Darbepoetin alfa has a longer half-life and can be given weekly or every 2 weeks at lower injection frequency. Start low and titrate — overshoot above 115 g/L increases cardiovascular risk and thrombosis.Epoetin alfa — available sa Pilipinas bilang Eprex (Janssen) at Eposino (Goodfellow) — ang pamantayang pangunahing ESA. Dosis: 4,000 IU subcutaneously 2–3 beses bawat linggo (o IV sa panahon ng dialysis). Ang Recormon (Roche) ay epoetin beta — isang natatanging molecular form na available sa 2,000 IU, 5,000 IU, at 10,000 IU prefilled syringe — at ginagamit din sa Pilipinas ngunit hindi epoetin alfa. Ang parehong alpha at beta form ay nagpapasigla ng parehong EPO receptor at may katulad na klinikal na bisa sa katumbas na dosis; gayunpaman hindi sila maaaring palitan nang unit-for-unit — kumpirmahin ang tiyak na agent at dosis sa inyong nephrologist. Ang darbepoetin alfa ay may mas matagal na half-life at maaaring ibigay lingguhan o bawat 2 linggo sa mas mababang dalas ng iniksyon. Magsimula nang mababa at mag-titrate — ang paglampas sa itaas ng 115 g/L ay nagpapataas ng cardiovascular risk at thrombosis.Epoetin alfa — available sa Pilipinas isip Eprex (Janssen) ug Eposino (Goodfellow) — ang pamantayang pangunahing ESA. Dosis: 4,000 IU subcutaneously 2–3 ka beses sa matag semana (o IV sa panahon sa dialysis). Ang Recormon (Roche) mao ang epoetin beta — usa ka lain nga molecular form nga available sa 2,000 IU, 5,000 IU, ug 10,000 IU prefilled syringe — ug gigamit usab sa Pilipinas apan dili epoetin alfa. Ang alpha ug beta form nagdasig sa pareho nga EPO receptor ug adunay katumbas nga klinikal nga epekto sa katumbas nga dosis; bisan pa dili sila mapuli sa unit-for-unit — kumpirmahon ang espesipikong agent ug dosis sa inyong nephrologist. Ang darbepoetin alfa adunay mas taas nga half-life ug mahimong ihatag matag semana o matag 2 ka semana sa mas ubos nga dalas sa iniksyon. Magsugod nga ubos ug mag-titrate — ang pagsabaw sa ibabaw sa 115 g/L nagpataas sa cardiovascular risk ug thrombosis.

Hemoglobin monitoring and targetPagmamasid sa hemoglobin at targetPagbantay sa hemoglobin ug target Pagmamasid king hemoglobin at target

Check hemoglobin regularly and use the lowest effective ESA dose. KDIGO 2026 advises against using ESAs to maintain hemoglobin at or above 115 g/L; if hemoglobin rises by more than 10 g/L in 2–4 weeks or nears 115 g/L, the dose is usually reduced rather than stopped; it may be paused if hemoglobin goes above 115 g/L. Raising hemoglobin into the normal range with ESAs has not been shown to improve heart or kidney outcomes and is linked to more strokes and heart attacks (CHOIR, TREAT trials). The aim is to ease symptoms and avoid transfusion, not to reach a "normal" number.Regular na suriin ang hemoglobin at gamitin ang pinakamababang epektibong dosis ng ESA. Nagpapayo ang KDIGO 2026 laban sa paggamit ng ESA upang panatilihin ang hemoglobin sa 115 g/L o mas mataas; kung tumaas ang hemoglobin nang higit sa 10 g/L sa loob ng 2–4 na linggo o papalapit sa 115 g/L, karaniwang binabawasan ang dosis sa halip na ihinto; maaari itong pansamantalang itigil kung lumampas sa 115 g/L. Ang pagtaas ng hemoglobin sa normal na saklaw gamit ang ESA ay hindi napatunayang nagpapabuti sa puso o bato at nauugnay sa mas maraming stroke at atake sa puso (CHOIR, TREAT). Ang layunin ay mapawi ang sintomas at maiwasan ang transfusion, hindi ang maabot ang "normal" na numero.Susihon kanunay ang hemoglobin ug gamita ang labing ubos nga epektibong dosis sa ESA. Ang KDIGO 2026 nagtambag batok sa paggamit sa ESA aron huptan ang hemoglobin sa 115 g/L o mas taas; kon mosaka ang hemoglobin og labaw sa 10 g/L sulod sa 2–4 ka semana o moduol sa 115 g/L, kasagaran kunhoran ang dosis imbes nga ihunong; mahimo kining ihunong sa makadiyot kon molapas sa 115 g/L. Ang pagpataas sa hemoglobin ngadto sa normal nga han-ay pinaagi sa ESA wala mapamatud-i nga makapaayo sa kasingkasing o kidney ug nalambigit sa mas daghang stroke ug atake sa kasingkasing (CHOIR, TREAT). Ang tumong mao ang paghupay sa sintomas ug paglikay sa transfusion, dili ang pagkab-ot sa "normal" nga numero. Regular a suriin ing hemoglobin at gamitan ing pekamababang epektibong dosis ning ESA. Magpayu ing KDIGO 2026 laban king pamangamit ning ESA para panatilian ing hemoglobin king 115 g/L o mas matas; nung tumaas ing hemoglobin lagpas 10 g/L king loob ning 2–4 lutu o papalapit ya king 115 g/L, karaniwang bawasan ing dosis kesa ihinto; malyari yang pansamantalang itigil nung lumampas ya king 115 g/L. Ing pagtaas ning hemoglobin king normal a saklaw gamit ing ESA ya ali mepatunayan a nagpapabuti king pusu o batu at me-link king mas dakal a stroke at atake king pusu (CHOIR, TREAT). Ing layunin ya mapawi ing sintomas at maiwasan ing transfusion, ali ing maabot ing "normal" a numeru.

ESA resistance — investigate before escalating dosePaglaban sa ESA — imbestigahan bago taasan ang dosisPagsukol sa ESA — imbestigahon sa wala pa taason ang dosis Paglaban king ESA — imbestigahan bago taasan ing dosis

If hemoglobin does not rise after 4–8 weeks despite adequate ESA dosing, do not simply increase the dose. Investigate: is iron truly adequate? Is there occult bleeding? Active infection or inflammation? Vitamin B12/folate deficiency? Hyperparathyroidism with marrow fibrosis? Anti-EPO antibodies (rare)? Each cause requires specific treatment, not more ESA.Kung ang hemoglobin ay hindi tumataas pagkatapos ng 4–8 linggo kahit may sapat na dosis ng ESA, huwag basta-basta taasan ang dosis. Imbestigahan: talaga bang sapat ang iron? May nakatagong pagdurugo? Aktibong impeksyon o pamamaga? Kakulangan ng Vitamin B12/folate? Hyperparathyroidism na may marrow fibrosis? Anti-EPO antibodies (bihira)? Ang bawat sanhi ay nangangailangan ng tiyak na paggamot, hindi mas maraming ESA.Kon ang hemoglobin dili mosaka human sa 4–8 ka semana bisan adunay igo nga dosis sa ESA, ayaw lang taason ang dosis. Imbestigahon: tinuod bang igo ang iron? Aduna bay naghisgot nga pagdugo? Aktibong impeksyon o pamamaga? Kakulang sa Vitamin B12/folate? Hyperparathyroidism nga adunay marrow fibrosis? Anti-EPO antibodies (panagsa)? Ang matag hinungdan nanginahanglan og espesipikong pagtambal, dili dugang ESA. Nung ing hemoglobin ya ali tumataas kapabanuan ning 4–8 lutu kahit atin sapat a dosis ning ESA, eka basta-basta taasan ing dosis. Imbestigahan: talaga bang sapat ing iron? Atin nakatagong pagdurugo? Aktibong impeksyon o pamamaga? Kakulangan ning Vitamin B12/folate? Hyperparathyroidism a atin marrow fibrosis? Anti-EPO antibodies (bihira)?

Enhance iron absorption with vitamin CPalakasin ang pagsipsip ng iron gamit ang vitamin CPalig-ona ang pagsuyop sa iron gamit ang vitamin C Palakasin ing pagsipsip ning iron gamit ing vitamin C

Vitamin C (ascorbic acid) converts non-heme iron (from plants) from ferric (Fe³⁺) to ferrous (Fe²⁺) form — the absorbable form. Squeeze calamansi or dalandan over iron-rich plant foods at mealtime. A small amount of vitamin C (50–100 mg) with oral iron supplements can increase absorption by 2–4 fold. Do not exceed 1,000 mg vitamin C supplementation — high doses increase urinary oxalate and kidney stone risk.Ang Vitamin C (ascorbic acid) ay nagko-convert ng non-heme iron (mula sa mga halaman) mula sa ferric (Fe³⁺) patungong ferrous (Fe²⁺) — ang masisipsip na anyo. Pigain ang calamansi o dalandan sa mga pagkaing may iron mula sa halaman sa oras ng kain. Ang maliit na halaga ng vitamin C (50–100 mg) kasama ang mga oral iron supplement ay maaaring magpataas ng pagsipsip ng 2–4 beses. Huwag lagpasan ang 1,000 mg ng vitamin C supplementation — ang mataas na dosis ay nagpapataas ng urinary oxalate at panganib ng kidney stone.Ang Vitamin C (ascorbic acid) nagbag-o sa non-heme iron (gikan sa mga tanum) gikan sa ferric (Fe³⁺) ngadto sa ferrous (Fe²⁺) — ang masuyop nga porma. Puga og calamansi o dalandan sa mga pagkaon nga may iron gikan sa tanum sa oras sa pagkaon. Ang gamay nga kantidad sa vitamin C (50–100 mg) uban sa mga oral iron supplement mahimong makapataas sa pagsuyop og 2–4 ka pilo. Ayaw lapasa ang 1,000 mg nga vitamin C supplementation — ang taas nga dosis nagpataas sa urinary oxalate ug peligro sa kidney stone. Ing Vitamin C (ascorbic acid) ya nagko-convert ning non-heme iron (mula king deng halaman) mula king ferric (Fe³⁺) patungong ferrous (Fe²⁺) — ing masisipsip a anyo. Pigain ing calamansi o dalandan king deng pagkaing atin iron mula king halaman king oras ning kain.

First choose your population — the thresholds are different for each. Then enter your iron panel to calculate TSAT and see how the numbers are interpreted. This tool evaluates and helps you discuss iron status with your doctor; it does not prescribe iron or decide the route (oral vs. IV) on its own. Interpretation follows KDIGO 2026.Piliin muna ang inyong populasyon — magkaiba ang mga threshold para sa bawat isa. Pagkatapos ilagay ang iron panel upang kalkulahin ang TSAT at makita kung paano binibigyang-kahulugan ang mga numero.

What this tool cannot decide: It cannot choose your population for you (you must select it), it cannot set a hemoglobin or ESA target, and it does not prescribe iron — it evaluates iron status and flags issues to discuss. A low TSAT with a high ferritin, or during active infection, is not proof of iron deficiency and should not by itself trigger IV iron. Any therapy needs clinician confirmation of the full picture. Source model: KDIGO 2026 Anemia-in-CKD guideline (reference values; individualization required).

⚕ TSAT = (Serum Iron ÷ TIBC) × 100. Ferritin is an acute phase reactant — elevated by inflammation, infection, or malignancy independent of iron stores. Classification per KDIGO 2026. This tool is for educational guidance only — iron therapy decisions require physician assessment.

Your kidney team checks why hemoglobin (Hb) is low before changing treatment. Iron tests and symptoms matter together. IV iron is usually preferred in hemodialysis; oral or IV iron can be chosen in non-dialysis CKD and peritoneal dialysis.

For adults taking an erythropoiesis-stimulating agent (ESA/EPO), the Hb goal is individualized and below 11.5 g/dL (115 g/L). More EPO is not a treatment for every cause of fatigue. Do not change your dose yourself.

The team usually withholds routine iron if ferritin is >700 ng/mL or TSAT ≥40%, and considers pausing it during systemic infection. These are treatment-review limits, not tests that prove iron overload.

Sinusuri ng kidney team ang sanhi ng mababang hemoglobin (Hb) bago baguhin ang gamutan. Magkasamang isinasaalang-alang ang iron tests at sintomas. Karaniwang mas pinipili ang IV iron sa hemodialysis; maaaring oral o IV iron sa CKD na hindi naka-dialysis at sa peritoneal dialysis.

Para sa adult na gumagamit ng erythropoiesis-stimulating agent (ESA/EPO), ang layunin sa Hb ay indibidwal at mas mababa sa 11.5 g/dL (115 g/L). Hindi dagdag na EPO ang lunas sa lahat ng sanhi ng pagod. Huwag baguhin ang dosis nang sarili lamang.

Karaniwang ipinagpapaliban ang regular na iron kung ferritin >700 ng/mL o TSAT ≥40%; maaaring pansamantalang ihinto ito habang may systemic infection. Hindi sapat ang mga numerong ito upang patunayang may iron overload.

Susihon sa kidney team ang hinungdan sa ubos nga hemoglobin (Hb) sa dili pa usbon ang tambal. Tan-awon ang iron tests uban sa mga sintomas. Kasagarang mas pilion ang IV iron sa hemodialysis; mahimong oral o IV iron sa CKD nga wala mag-dialysis ug sa peritoneal dialysis.

Sa hamtong nga naggamit og erythropoiesis-stimulating agent (ESA/EPO), ang tumong sa Hb ipahaom sa pasyente ug ubos sa 11.5 g/dL (115 g/L). Dili dugang EPO ang tubag sa tanang hinungdan sa kakapoy. Ayaw usba ang dosis sa imong kaugalingon.

Kasagarang dili ihatag ang regular nga iron kon ferritin >700 ng/mL o TSAT ≥40%; mahimong ihunong kini sa makadiyot panahon sa systemic infection. Kini nga mga numero dili igo nga pamatuod sa iron overload.

Suriin na ning kidney team ing sangkan ning mababang hemoglobin (Hb) bayu baguan ing gamutan. Lawan la deng iron tests kayabe deng sintomas. Karaniwang mas pipilinan ing IV iron king hemodialysis; malyaring oral o IV iron king CKD a e pa maki-dialysis at king peritoneal dialysis.

Anemia in CKD: Clinical Management Guide

KDIGO 2026-aligned protocols for iron optimization, ESA dosing, HIF-PHI integration, and dialysis-specific anemia workflows. Evidence-based decision support for nephrologists and internists.

Summary

Workup. Start with a complete blood count, reticulocyte count, ferritin and transferrin saturation; kidney disease does not exclude another cause, and a ferritin below 45 ng/mL warrants evaluation for bleeding (KDIGO 2026).

Treatment. Optimize iron and individualize erythropoiesis-stimulating agent (ESA) therapy. ESA should not be used to maintain hemoglobin at or above 115 g/L, and targets above 130 g/L raised cardiovascular events and stroke in CHOIR and TREAT. The guide also covers hyporesponse, hypoxia-inducible factor prolyl hydroxylase inhibitors, transfusion and dialysis workflows.

KDIGO 2026 Aligned CKD ND · HD · PD ESA Protocols Iron Titration HIF-PHI Overview Dialysis-Focused

Quick Clinical Overview

Start with a complete blood count (CBC), reticulocyte count, ferritin, and transferrin saturation (TSAT). Adult anemia is Hb <13 g/dL in men or <12 g/dL in women; pediatric thresholds are age-specific. Kidney disease does not exclude another cause.

If the initial tests do not explain anemia, tailor further testing: smear, haptoglobin/lactate dehydrogenase, C-reactive protein, B12/folate, liver tests, thyroid-stimulating hormone, parathyroid hormone, and monoclonal-protein studies. Assess blood loss and nutrition. Ferritin <45 ng/mL, or unexplained microcytosis without a ferritin result or known genetic cause, warrants evaluation for bleeding and appropriate referral (practice points 1.2.1–1.2.3, S19–20).

WHO / KDIGO Diagnostic Thresholds

Men
Anemia < 130 g/L
Women
Anemia < 120 g/L
ESA goal
Below 115 g/L (individualized)
ESA maintenance
Do NOT use ESA to keep Hb ≥ 115

KDIGO 2026: CKD anemia = Hb below sex-specific threshold without obvious non-renal cause. There is no single universal Hb target/initiation threshold; individualize by population (CKD ND, HD, PD, transplant, pediatric) and by symptoms, Hb trajectory, transfusion-avoidance and transplant candidacy via shared decision-making. Do not use ESAs to maintain Hb ≥115 g/L. Evaluate at any CKD stage. Test at least annually in CKD G3, twice a year in G4, and every 3 months in G5/G5D (Figure 5); more often on ESA or HIF-PHI therapy, below target, or with rapid CKD progression.

Pathophysiology at a Glance

  • EPO deficiency — decreased interstitial fibroblast EPO synthesis proportional to GFR loss; dominant mechanism in advanced CKD
  • Hepcidin excess — inflammation + reduced renal clearance → iron sequestration, impaired duodenal absorption, blocked ferroportin
  • Shortened RBC lifespan — uremic toxins accelerate RBC destruction; normal 120d → ≈60–80d in ESKD
  • Marrow suppression — uremic toxins, hyperparathyroidism-driven fibrosis
  • Blood loss — dialyzer clotting, frequent phlebotomy, occult GI bleeding

Top 5 Missed Causes in CKD

  1. Concurrent iron deficiency — especially absolute IDA from GI blood loss or menorrhagia (TSAT <20%, ferritin <100); missed when EPO deficiency assumed
  2. B12 / Folate deficiency — common in dialysis; dialysis removes water-soluble vitamins; CBC shows macrocytosis masked by microcytosis
  3. Underdialysis — Kt/V <1.2 raises uremic toxin burden → EPO hyporesponsiveness; check URR and Kt/V in resistant anemia
  4. Hyperparathyroidism — severe secondary hyperparathyroidism can cause marrow fibrosis and blunt erythropoiesis; treat it for its own indication
  5. Pure Red Cell Aplasia (PRCA) — rare but serious; anti-EPO antibodies after subcutaneous epoetin; suspect if Hb drops precipitously on ESA; requires bone marrow biopsy confirmation
🩺 Clinical Pearl

In a dialysis patient with ESA hyporesponsiveness: check TSAT and ferritin first. Iron-restricted erythropoiesis is the most common reversible cause. In HD, KDIGO 2026 suggests IV iron when ferritin is ≤500 ng/mL and TSAT ≤30%, and the Hb response often allows a lower ESA dose.

⚠️ Diagnostic Pitfall

Serum ferritin is an acute-phase reactant: in infection or inflammation, a ferritin above 500 ng/mL does not exclude iron-restricted erythropoiesis. In HD, ferritin 500–700 ng/mL with low TSAT is outside the KDIGO 2026 initiation criteria but below the withhold limit, so treat the cause and individualize; withhold routine iron if ferritin exceeds 700 ng/mL or TSAT reaches 40%.

Initial Anemia Workup

Essential
CBC with differential
Hb, MCV, MCHC, reticulocyte count; MCV <80 fL = microcytic; >100 fL = macrocytic
Iron Studies
Serum iron, TIBC, ferritin, TSAT
TSAT = (serum iron ÷ TIBC) × 100; repeat at minimum q3 months in HD patients
Reticulocytes
Reticulocyte Hb content (CHr/RetHe)
CHr <29 pg = iron-restricted erythropoiesis even when ferritin "normal"; best early iron deficiency marker
Vitamins
Serum B12, folate (RBC folate preferred)
Supplement empirically in dialysis; losses occur each session
Renal
PTH, albumin, CRP/ESR
High PTH → marrow fibrosis; CRP elevation → functional iron deficiency, EPO hyporesponsiveness
GI Screen
Fecal occult blood (if indicated)
GI blood loss 2–3× more common in CKD; consider endoscopy if TSAT <20% with unexplained IDA
Dialysis
Kt/V or URR (HD/PD patients)
Underdialysis is a reversible cause of EPO hyporesponsiveness; HD target spKt/V ≥1.4 (minimum 1.2)
PRCA Screen
Anti-EPO antibodies (if suspected)
Suspect if Hb falls about 5–10 g/L per week on an established ESA, with reticulocytes <10,000/µL; confirm with antibody testing and marrow examination

Population / decisionKDIGO 2026 guidance
Anemia + hemodialysis (HD): initiate ironFerritin ≤500 ng/mL and TSAT ≤30%. IV iron is suggested; use a proactive, monitored approach.
Anemia + non-dialysis CKD or peritoneal dialysis (PD): initiate ironFerritin <100 ng/mL and TSAT <40%, or ferritin ≥100 and <300 ng/mL and TSAT <25%.
Route outside HDChoose oral or IV iron using severity, response, tolerance, preference, availability, and cost. Switch an optimal oral regimen to IV if ineffective after 1–3 months or poorly tolerated.
Withhold routine ironFerritin >700 ng/mL or TSAT ≥40%. An elevated ferritin alone does not diagnose iron overload.
Systemic infectionConsider temporarily suspending iron. Inflammation without infection needs clinical assessment rather than an automatic infection diagnosis.
Monitoring during iron treatmentHb, ferritin, TSAT every 3 months in non-dialysis CKD/PD; every 1–3 months in HD, often monthly. Test sooner after blood loss, hospitalization, ESA escalation, or rapidly changing iron indices.
DecisionKDIGO 2026 guidance
Adult HD or PD: consider initiationAfter reversible causes are addressed, consider ESA when Hb is ≤9–10 g/dL. Select the threshold within that range using symptoms, risks, and patient preferences.
Non-dialysis CKD, including transplant recipientsIndividualize initiation using symptoms, potential benefit, transfusion avoidance, ESA risks, and preferences; Hb <10 alone is not an automatic start order.
Adult maintenance goalTarget Hb below 11.5 g/dL (115 g/L), individualized. A common working range is about 10 to <11.5 g/dL; this is not an anemia diagnostic range.
Dose changesUse the lowest effective dose. Generally avoid adjustments more often than every 4 weeks. If Hb rises >1 g/dL in 2–4 weeks, reduce by 25–50%. Prefer reduction to holding while Hb does not exceed 11.5, as clinically appropriate.
MonitoringHb every 2–4 weeks after initiation or adjustment; at least every 3 months during maintenance, usually more often in HD.
Stroke, thrombosis, and cancerConsider suspending ESA during hospitalization for acute stroke, vascular access thrombosis, or thromboembolism. Active or previous cancer calls for shared decision-making, especially when treatment aims at cure. Uncontrolled hypertension and product-specific contraindications require review.

Iron Therapy

Ferric carboxymaltose can cause hypophosphatemia, especially with repeated treatment; monitor when indicated. Administer IV iron where hypersensitivity and hypotension can be treated. Respect the maximum dose and rate for the particular formulation; a suggested course is not an order for every CKD population.

IV Iron Formulations

Iron Sucrose (Ferrofer® / Venofer® / Anema®)
Dose (HD)100 mg IV per dialysis session for up to 10 sessions (1,000 mg). Maintenance per unit protocol; PIVOTAL used 400 mg/month, held at ferritin >700 ng/mL or TSAT ≥40%
Dose (CKD ND/PD)Non-dialysis: 200 mg × 5 doses over about 5 weeks (1,000 mg). PD: 300 mg × 2, 14 days apart, then 400 mg 14 days later. Maximum single dose 200 mg (PD 400 mg; KDIGO 2026 Table 4)
SafetyGood; lower anaphylaxis risk than iron dextran; test dose not required
PhilippinesWidely available; first-line IV iron in most Philippine dialysis centers
Ferric Carboxymaltose (Ferinject®)
DoseUp to 20 mg/kg (max 1,000 mg) per infusion over ≥15 min; a second dose ≥7 days later if needed (some labels: 750 mg × 2)
AdvantageHigh single-dose capability; no test dose; ideal for outpatient repletion in CKD ND
CautionHypophosphatemia (FGF-23 mediated); monitor phosphate, particularly in kidney transplant recipients, earlier-stage CKD, and with repeated dosing (KDIGO 2026)
PhilippinesAvailable; higher cost than iron sucrose
Ferric Derisomaltose (Monofer®)
DoseUp to 20 mg/kg as a single infusion (over ≥15 min for doses ≤1,000 mg; ≥30 min above)
AdvantageTotal-dose repletion in one visit; lower hypophosphatemia rate than ferric carboxymaltose (PHOSPHARE trials)
PhilippinesConfirm FDA Philippines registration and local availability
Sodium Ferric Gluconate (Ferrlecit®)
Dose125 mg IV per HD session × 8 sessions; dilute in 100 mL NS, infuse over 1 hour
SafetyGood; anaphylaxis rare; lower iron content per vial than iron sucrose
NoteRequires more sessions for full repletion; useful when small incremental dosing preferred
Low Molecular Weight Iron Dextran (INFeD®)
DoseTotal-dose infusion (max 20 mg/kg) or divided doses; test dose only if the local label requires it (KDIGO 2026: test doses are not usually needed)
RiskHighest anaphylaxis risk among IV irons; high molecular weight dextran (Dexferrum®) carries greater risk — avoid
NoteUse only when other formulations unavailable; have resuscitation equipment ready
⛔ Systemic Infection

Iron supports bacterial growth. KDIGO 2026 suggests considering a temporary pause in iron during systemic infection; restart once the infection is controlled and indices are reassessed. Inflammation without infection needs clinical assessment rather than an automatic hold.

⛔ Withhold Limits

Withhold routine iron when ferritin exceeds 700 ng/mL or TSAT reaches 40% (KDIGO 2026), then recheck before restarting. An elevated ferritin alone does not diagnose iron overload; correlate with TSAT, inflammation, and transfusion history.

Each IV dose should not exceed the maximum single dose of the formulation (KDIGO 2026 practice point 2.9). Administer where hypersensitivity and hypotension can be treated. Size a course with the Ganzoni calculator.

Key ESA Risks

Cardiovascular & Thrombotic Risks

  • Higher Hb targets (about 130–135 g/L vs about 100–115 g/L) → ↑ stroke, cardiovascular events, and AV access thrombosis
  • ESA-stimulated erythropoiesis → ↑ platelet aggregation, blood viscosity
  • Hypertension exacerbation common; check BP at each visit during initiation
  • TREAT trial: darbepoetin targeting Hb 130 g/L about doubled stroke risk (HR 1.92)

Tumor Promotion Concern

  • EPO receptors expressed on some solid tumors (breast, head & neck, lung)
  • ESA in chemotherapy-related anemia associated with shorter survival in some RCTs

Transferrin saturation

Investigate iron deficiency or iron-restricted erythropoiesis, inflammation/infection, bleeding, hemolysis, nutritional deficiency, hyperparathyroidism, inadequate dialysis, adherence, and marrow disease before escalating an erythropoiesis-stimulating agent (ESA). A sudden Hb decline with severe reticulocytopenia raises concern for pure red cell aplasia and requires specialist evaluation.

The ESA resistance index (ERI) is weekly epoetin dose ÷ weight ÷ Hb in g/dL. It is a longitudinal exposure/response measure, not a stand-alone diagnosis or instruction to maintain a dose. KDIGO 2026 Table 10 summarizes heterogeneous definitions; ERI 10 is not a universal KDIGO cutoff. Darbepoetin-to-epoetin conversions are approximate and dose-dependent; do not apply a fixed 200-IU/µg factor to CERA as a validated conversion.

Causes Checklist

Iron & Nutrition

  • Absolute iron deficiency (TSAT <20%, ferritin <100)
  • Iron-restricted erythropoiesis (low TSAT with normal or high ferritin)
  • Vitamin B12 deficiency (check serum B12, homocysteine)
  • Folate deficiency (common in dialysis — dialysis-related losses)
  • Malnutrition / low albumin (ESA response correlates with nutritional status)

Systemic / Dialysis Factors

  • Active infection or inflammation (↑ CRP → ↑ hepcidin → iron sequestration)
  • Underdialysis (Kt/V <1.2): uremic toxin accumulation suppresses erythropoiesis
  • Severe secondary hyperparathyroidism (marrow fibrosis)
  • Hemolysis (check LDH, reticulocytes, haptoglobin)
  • Occult blood loss (GI, dialyzer clotting, access bleeding)
  • ACE inhibitor or ARB use (small, inconsistent effect; rarely a reason to stop)

Pure Red Cell Aplasia (PRCA) — Rule Out

Suspect PRCA when: (1) Hb falls rapidly (about 5–10 g/L per week, or transfusion becomes necessary) on established ESA therapy, (2) reticulocyte count <10,000/µL, (3) other cytopenias absent. Confirm: anti-EPO antibody titer (reference lab) + bone marrow biopsy (erythroid hypoplasia with normal myeloid/platelet lineages). Manage: Stop all ESA immediately — do NOT switch brands (antibodies cross-react). Immunosuppression (prednisolone ± cyclophosphamide or cyclosporine). KDIGO 2026 (practice point 3.7.6): discontinue the ESA, transfuse as clinically appropriate, and consider hematology referral, immunosuppression, and a HIF-PHI for subsequent anemia treatment. Kidney transplant often resolves PRCA. Do NOT restart any ESA until antibody-negative and erythroid recovery confirmed. Report to pharmacovigilance.

HIF Prolyl Hydroxylase Inhibitor (HIF-PHI) Therapy

After correcting reversible causes, an ESA is generally suggested before a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI). A selected patient with ESA hyporesponsiveness may consider a HIF-PHI trial to relieve symptoms or avoid transfusion, with explicit discussion that evidence for clinical benefit and safety in this group is limited.

  • Do not combine an ESA and a HIF-PHI.
  • Review active malignancy, recent cardiovascular or thrombotic events, and the agent’s local authorization and contraindications.
  • Use the lowest effective dose and monitor Hb every 2–4 weeks after initiation or changes.
  • Discontinue a trial for hyporesponsiveness after 3–4 months without the desired erythropoietic response.

Correct documented nutritional deficiencies and manage CKD mineral/bone disease for their indications. Vitamin D or L-carnitine should not be presented as proven routine KDIGO anemia therapy; adjunct studies do not establish patient-important benefit for every hyporesponder.

HIF-PHI Mechanism of Action — PHD inhibition, HIF stabilization, endogenous EPO production, improved iron utilization, increased RBC production

This diagram explains how HIF-PHI tablets work: they block the enzyme that breaks down HIF, which raises the body’s own EPO, improves iron absorption, and lowers hepcidin, leading to more red blood cells.

HIF
Hypoxia-inducible factor
PHD
Prolyl hydroxylase domain enzyme
HIF-PHI
HIF prolyl hydroxylase inhibitor
EPO
Erythropoietin
DMT1
Divalent metal transporter 1
RBC
Red blood cell

Mechanism of Action

HIF-PHIs inhibit prolyl hydroxylase domain (PHD) enzymes, preventing HIFα degradation. Stabilized HIF-1α/HIF-2α translocate to the nucleus → transcription of EPO (liver & kidney), iron absorption genes (DMT1, ferroportin), and transferrin receptor. Net effect: ↑ endogenous EPO + improved iron mobilization, partially overcoming hepcidin-mediated iron restriction.

⚠️ Safety Signals — Agent- and Setting-Specific

KDIGO 2026: in dialysis there may be little or no difference from ESAs in mortality and major adverse cardiovascular events (MACE); in non-dialysis CKD, some HIF-PHIs may carry a higher risk of MACE and vascular access thrombosis (for example, vadadustat missed MACE non-inferiority in PRO2TECT). Avoid HIF-PHIs with active or recent cancer, prior stroke, myocardial infarction or thromboembolism, prior access thrombosis, polycystic kidney disease, proliferative retinopathy, pulmonary arterial hypertension, pregnancy, or significant hepatic impairment (Table 6). Do not combine with an ESA. Confirm FDA Philippines registration before counseling a patient that a HIF-PHI is available.

Transfusion Strategy in CKD Anemia

For chronic anemia in CKD, base red-cell transfusion on symptoms and signs attributable to anemia and the individual balance of benefits and harms, rather than an arbitrary Hb threshold (practice point 4.4). Restrictive thresholds from other settings are context-specific and are not universal CKD orders.

Acute hemorrhage, unstable coronary disease, or urgent surgery may require rapid correction. Avoid transfusion when possible in transplant candidates to reduce allosensitization. Leukoreduction does not eliminate sensitization risk. When transfusion is appropriate, account for volume overload, potassium, iron burden, and reassess the response; stable patients are often managed one unit at a time under local protocols.

Why to Avoid pRBC Transfusion in CKD

Pre-Transplant Sensitization

Each transfusion exposes the recipient to foreign HLA antigens → panel reactive antibody (PRA) formation. A high PRA narrows the compatible donor pool and lengthens waiting time. If transfusion is unavoidable in a transplant candidate, leukoreduced blood is used, but it does not eliminate sensitization risk.

Iron Overload, Volume & CV Risk

  • Each pRBC unit contains ~200–250 mg iron → hemosiderosis with repeated transfusions
  • Volume overload risk in anuric ESKD patients; transfuse during dialysis session if possible
  • Transfusion-associated circulatory overload (TACO) risk in fluid-restricted HD patients
  • Alloimmunization, febrile reactions, TRALI (rare)

Source: KDIGO 2026 Anemia in CKD, recommendations 2.1–2.4 and 3.2.1–3.3.1; practice points 2.2–2.8 and 3.4.1.2–3.4.3.5. Reviewed November 6, 2026. Apply clinical judgment and the locally approved product label.

Dialysis-Specific Anemia Management

Review missed/shortened sessions, access or circuit blood loss, dialysis adequacy, volume status, and nutrition. PD is grouped with non-HD patients for iron initiation and route selection; PD does not automatically require IV iron. ESA initiation in PD follows the dialysis recommendation.

Anemia Contributors in Hemodialysis Patients — blood losses, repeated lab draws, GI bleeding, catheter inflammation, inflammatory cytokines, reduced erythropoiesis

This figure shows extra factors that worsen anemia in people on hemodialysis: blood left in the tubing or lost to clotting, repeated lab draws, gut bleeding, catheter-related inflammation, inflammatory cytokines, and reduced red-cell production.

GI
Gastrointestinal
TNF-α
Tumor necrosis factor-alpha
IL-6
Interleukin-6

HD Blood Losses

  • Circuit losses: a few mL of residual blood each session, and a full circuit (often 150–250 mL) if it clots; optimize anticoagulation and rinse-back
  • Needle access: AV fistula needle trauma; needle gauge and technique affect blood loss
  • Frequent phlebotomy: routine sampling adds up and, with circuit and GI losses, keeps iron needs ongoing in HD; use small-volume tubes
  • Occult GI bleeding: Uremia → platelet dysfunction, angiodysplasia; annual FOBT or endoscopy if unexplained IDA

Dialysis Adequacy & Anemia

Kt/V <1.2 → EPO hyporesponsiveness. Uremic toxins (indoxyl sulfate, ADMA) directly suppress erythropoiesis and shorten RBC lifespan. Improving dialysis adequacy often reduces ESA requirement.

  • Check Kt/V at least monthly to quarterly per unit protocol; HD target spKt/V ≥1.4 (minimum 1.2)
  • Increase session length or frequency if Kt/V suboptimal
  • High-flux dialysis improves middle molecule clearance and may improve ESA response
  • PD: maintain adequacy (weekly Kt/V ≥1.7 is the traditional minimum), alongside clinical well-being

PD-Specific Considerations

  • Lower blood losses: PD patients have less dialyzer-related blood loss than HD, but peritoneal cavity protein losses can impair ESA response
  • SC ESA preferred: Subcutaneous epoetin or darbepoetin 1–3×/week; CERA monthly SC excellent compliance tool in PD
  • IP EPO: Intraperitoneal administration achieves systemic levels but absorption variable; not standard practice
  • Iron: PD uses the non-HD KDIGO 2026 criteria (ferritin <100 ng/mL and TSAT <40%, or ferritin 100 to <300 and TSAT <25%); oral or IV iron, switching to IV if oral fails after 1–3 months

Practical Clinical Algorithms

  1. Confirm anemia and evaluate reversible causes.
  2. Select HD versus non-HD/PD iron criteria; check both ferritin and TSAT.
  3. Review routine iron withhold limits and systemic infection before treatment.
  4. Reassess Hb and symptoms; individualize ESA initiation by population.
  5. Use the lowest effective ESA dose, targeting Hb below 11.5 g/dL in adults; monitor and evaluate hyporesponsiveness.

Algorithm A: New or Worsening Low Hb in CKD

1
Confirm Anemia

Hb <130 g/L (men) or <120 g/L (women) on repeat CBC. Exclude lab error or dilution (sample drawn near an IV line or from the access).

2
Iron Workup First

Check TSAT and ferritin from the same draw and apply the KDIGO 2026 criteria: HD — ferritin ≤500 ng/mL and TSAT ≤30%; non-HD CKD/PD — ferritin <100 and TSAT <40%, or ferritin 100 to <300 and TSAT <25%. IV iron in HD; oral or IV elsewhere. Recheck Hb and iron indices in 1–3 months.

3
Exclude Non-Renal Causes

MCV: microcytic → iron deficiency or thalassemia trait; macrocytic → B12/folate. Check reticulocytes, B12, folate, CRP, LDH, haptoglobin, and stool occult blood. With ferritin <45 ng/mL, or microcytosis without a ferritin result or known genetic cause, consider evaluation for blood loss.

4
ESA Initiation Decision

After reversible causes are addressed: in HD or PD, consider an ESA when Hb is ≤90–100 g/L; in non-dialysis CKD, individualize using symptoms, transfusion avoidance, ESA risks, and preferences. Extra caution with active or previous cancer, recent stroke, or thrombosis.

5
Titrate and Monitor

Use the lowest effective dose and do not use an ESA to maintain Hb ≥115 g/L. If Hb rises >10 g/L in 2–4 weeks, reduce the dose by 25–50%. Check Hb every 2–4 weeks after a change and at least every 3 months during maintenance.

Algorithm B: Low TSAT with High Ferritin (Iron-Restricted Erythropoiesis)

1
Define the Pattern

Low TSAT with normal or high ferritin. Hepcidin traps iron in stores, so circulating iron is low despite adequate total body iron.

2
Look for the Driver

Check CRP and look for infection, recent surgery, access-related inflammation, or malignancy. Treat the cause where possible; consider pausing iron during systemic infection.

3
Within Initiation Criteria

HD with ferritin ≤500 ng/mL and TSAT ≤30% (or non-HD/PD criteria met): IV iron is suggested in HD; recheck Hb and indices in about 4 weeks.

4
HD Ferritin 500–700: Individualize

Outside the initiation criteria but below the withhold limit. Treat inflammation and review the trend; a monitored IV iron course may still help selected patients (DRIVE: ferritin 500–1,200 ng/mL, TSAT ≤25%).

5
Ferritin >700 or TSAT ≥40%: Withhold

Withhold routine iron and recheck. High ferritin alone does not prove overload; assess for iron overload only when the history suggests it (for example, heavy transfusion burden). KDIGO notes a trial course may still be considered for some patients with TSAT <20% and refractory anemia or high ESA requirements.

Case-Based Clinical Pearls

ExampleInterpretation
Non-dialysis CKD, anemia, ferritin 80 ng/mL, TSAT 35%Meets suggested iron-initiation criteria. Choose oral or IV treatment with the patient; TSAT >30% alone is not a reason to withhold.
HD, ferritin 600 ng/mL, TSAT 20%, already receiving ironOutside suggested initiation criteria but below routine withhold limits. Review ongoing treatment, trends, inflammation, symptoms, and response; do not apply an automatic 500-ng/mL stop.
Any adult CKD, ferritin 750 ng/mL or TSAT 40%Withhold routine iron and evaluate. High ferritin is not proof of iron overload.
Adult on ESA, Hb 11.5 g/dLAt the boundary excluded by the maintenance target. Review dose reduction and trend; do not simply label it in range.

Worked Cases

Case 1
HD Patient — ESA Hyporesponsiveness with Elevated Ferritin
Hb 85 g/L TSAT 14% Ferritin 620 ng/mL CRP 48 mg/L Epoetin 400 IU/kg/week Kt/V 1.38

Presentation: 58-year-old male on HD × 4 years. Hb declining over 3 months despite epoetin dose escalations. Currently on 400 IU/kg/week. Ferritin reported as "elevated" — no IV iron given. AV fistula revision surgery 6 weeks prior.

Analysis & Management

Ferritin is raised by post-surgical inflammation (CRP 48); TSAT 14% shows iron-restricted erythropoiesis. Ferritin 620 ng/mL is outside the KDIGO 2026 HD initiation criteria (≤500) but below the withhold limit (>700), so this is an individualized decision. Action: (1) treat the inflammatory source and stop escalating the ESA; (2) a monitored IV iron course is reasonable here (DRIVE supported iron at ferritin 500–1,200 ng/mL with TSAT ≤25%); (3) recheck Hb, ferritin, and TSAT in about 4 weeks. Never escalate the ESA without first addressing iron availability.

Case 2
PD Patient — New Anemia, Don't Miss Non-Renal Causes
Hb 78 g/L (was 105 g/L × 6 months) MCV 72 fL TSAT 12% Ferritin 28 ng/mL Peritoneal Kt/V 1.8

Presentation: 67-year-old female on CAPD × 2 years. Previously stable Hb on darbepoetin 0.45 µg/kg/week. New microcytic anemia over 6 weeks. No dose change. Peritoneal adequacy maintained. No abdominal symptoms.

Analysis & Management

New microcytic anemia + low TSAT + low ferritin = absolute iron deficiency. In a stable PD patient, this is NOT explained by EPO deficiency alone (EPO deficiency causes normocytic anemia). New IDA demands investigation for blood loss. (1) FOBT and GI evaluation (angiodysplasia risk in elderly CKD patients); (2) check for menorrhagia in younger women. Ferritin <45 ng/mL warrants considering an evaluation for blood loss (KDIGO 2026 practice point 1.2.3). Start iron (iron sucrose 200 mg IV × 2–3 doses, or oral iron if preferred and tolerated). GI endoscopy revealed sigmoid angiodysplasia → argon plasma coagulation. Hb recovered to 108 g/L on same ESA dose.

Case 3
CKD ND — Hb Overshooting on ESA
Hb 138 g/L (was 98 g/L × 12 weeks ago) Darbepoetin 0.45 µg/kg weekly × 12 weeks TSAT 38% BP 165/98 mmHg

Presentation: 52-year-old male, CKD G4 (eGFR 18). Started darbepoetin 12 weeks ago. Hb rose rapidly from 98 → 138 g/L. BP poorly controlled. Patient feels "great" and is reluctant to reduce dose.

Analysis & Management

Hb 138 g/L after a 40 g/L rise is above the KDIGO 2026 goal (below 115 g/L) and the rise was too fast (>10 g/L in 2–4 weeks should prompt a 25–50% reduction). CHOIR: targeting 135 rather than 113 g/L increased the composite of death and cardiovascular events (HR 1.34). Action: (1) hold or substantially reduce darbepoetin; (2) control blood pressure; (3) recheck Hb every 2–4 weeks; (4) resume at a 25–50% lower dose once Hb is falling and below 115 g/L. Counsel: a higher Hb raises stroke and access-thrombosis risk; the goal is the lowest effective dose, not the highest tolerated Hb.

Case 4
HD Patient — Suspected Pure Red Cell Aplasia (PRCA)
Hb 64 g/L (dropped 28 g/L in 6 weeks) Reticulocytes <5,000/µL Normal WBC & platelets SC epoetin alfa × 3 years TSAT 32%, Ferritin 410 CRP normal

Presentation: 61-year-old male on HD. Hb stable at 105–112 g/L for years on epoetin alfa 150 IU/kg SC 3×/week. Over 6 weeks: Hb plummets to 64 g/L. Iron studies adequate. CRP normal. No GI symptoms. Reticulocytes severely suppressed.

Analysis & Management

PRCA must be ruled out. Hallmarks: rapid Hb fall on established ESA, severe reticulocytopenia, normal other cell lines, adequate iron, no infection. Action: (1) STOP epoetin alfa immediately — do NOT switch to another brand (antibodies cross-react with all epoetin-class agents including biosimilars); (2) anti-EPO antibody titer (send serum to reference lab); (3) bone marrow biopsy (erythroid hypoplasia with normal myeloid/megakaryocyte lineages); (4) transfuse as needed for symptomatic anemia; (5) if PRCA confirmed: prednisolone 1 mg/kg/day ± cyclosporine or cyclophosphamide; (6) consider accelerated transplant listing — transplant often resolves PRCA. Report case to pharmacovigilance authority.

Patient handout: understanding your anemia

Your kidney team checks why hemoglobin (Hb) is low before changing treatment. Iron tests and symptoms matter together. IV iron is usually preferred in hemodialysis; oral or IV iron can be chosen in non-dialysis CKD and peritoneal dialysis.

For adults taking an erythropoiesis-stimulating agent (ESA/EPO), the Hb goal is individualized and below 11.5 g/dL (115 g/L). More EPO is not a treatment for every cause of fatigue. Do not change your dose yourself.

The team usually withholds routine iron if ferritin is >700 ng/mL or TSAT ≥40%, and considers pausing it during systemic infection. These are treatment-review limits, not tests that prove iron overload.

🫘 What Is Anemia?

Your kidneys normally make a hormone called erythropoietin (EPO) that tells your bone marrow to produce red blood cells. In CKD, damaged kidneys make less EPO — without this signal, your body makes fewer red blood cells. Fewer red blood cells means less oxygen reaches your organs.

Anemia becomes more common as kidney function falls
😴 How You May Feel
  • Unusual tiredness or weakness
  • Pale or yellowish skin
  • Feeling cold all the time
  • Dizziness or lightheadedness
  • Shortness of breath with activity
  • Fast or fluttering heartbeat
  • Difficulty concentrating
💊 Your Treatment Plan

Iron supplements — Oral iron tablets or IV iron drip given at dialysis. Iron feeds your red blood cells.

EPO injections (ESA) — A medicine that signals your bone marrow to make red blood cells, replacing what your kidneys can't produce. Common brands: Recormon (epoetin beta), Eprex / Eposino (epoetin alfa), Nesp (darbepoetin alfa, weekly), Mircera (monthly injection).

Iron-rich foods — Red meat, dark leafy greens, beans, fortified cereals. Ask your dietitian for a kidney-safe food list.

📞 Call Your Doctor If:
  • You feel much more tired than usual
  • Chest pain or shortness of breath at rest
  • You appear unusually pale
  • Fever, chills, or signs of infection
  • Dark or bloody stools
  • Dizziness or fainting
Regular blood tests are key. Your hemoglobin, iron levels, and EPO response are checked regularly (usually monthly on dialysis). Work closely with your nephrologist — managing anemia protects your heart and kidneys.

Future Directions

Hepcidin-targeted agents, biomarkers, and algorithm-assisted dosing remain areas of research. They do not replace the current population-specific iron criteria, individualized ESA decisions, or monitoring. An illustration of a future system is not a validated dose recommendation.

AI-Guided ESA & Iron Dosing

Machine-learning models are being studied to predict Hb response to ESA and IV iron dose changes. Early HD cohort studies report less Hb variability than protocol-based dosing, but prospective outcome data are still limited.

Hepcidin-Targeted Therapies

Hepcidin is the central driver of functional iron deficiency in CKD. Early-phase approaches include hepcidin antagonists (for example, lexaptepid pegol, a hepcidin-binding oligonucleotide), agents that reduce hepcidin production, and ferroportin-targeted therapies. These could fundamentally change management of high-ferritin functional-IDA patients resistant to conventional IV iron.

Precision Iron Phenotyping

Emerging biomarkers beyond TSAT/ferritin: reticulocyte Hb content (CHr/RetHe), soluble transferrin receptor (sTfR), sTfR/log ferritin index, hepcidin-25 levels, zinc protoporphyrin. Multi-marker panels may allow precision iron subtype classification (absolute IDA vs. functional IDA vs. iron-restricted erythropoiesis vs. iron overload) and guide individualized therapy.

Next-Generation ESA & Alternatives

Pipeline agents: (1) activin receptor ligand traps (sotatercept — approved for PAH, under study in CKD anemia) that stimulate late-stage erythropoiesis via TGF-β superfamily inhibition; (2) siRNA therapies targeting liver hepcidin production; (3) non-EPO-structured EPO receptor agonists (peginesatide was withdrawn in 2013 for serious hypersensitivity reactions). These may address refractory anemia and ESA hyporesponsiveness where current therapies fail.
