Hepcidin and risk of anemia in CKD: a cross-sectional and longitudinal analysis in the CKiD cohort
Background Hepcidin, a key iron regulatory protein, is elevated in patients with chronic kidney disease (CKD). Its role in the development and progression of the anemia of CKD in children remains poorly defined. Methods Cross-sectional and longitudinal study in children aged 1–16 years with stage 2–...

Cross-sectional and longitudinal study in children aged 1–16 years with stage 2–4 CKD in the Chronic Kidney Disease in Children (CKiD) cohort (

Hepcidin, a key iron regulatory protein, is elevated in patients with chronic kidney disease (CKD). Its role in the development and progression of the anemia of CKD in children remains poorly defined.
Methods
Cross-sectional and longitudinal study in children aged 1–16 years with stage 2–4 CKD in the Chronic Kidney Disease in Children (CKiD) cohort (
n
= 133) with hepcidin measured at baseline and hemoglobin (HGB) measured annually at follow-up. Anemia was defined as HGB <5th percentile for age/sex OR treatment with an erythropoiesis-stimulating agent (ESA).
Results
Hepcidin levels correlated negatively with glomerular filtration rate (GFR;
r
= −0.22,
p
= 0.01) and positively with ferritin (
r
= 0.67,
p
< 0.001). At the lower end of the GFR spectrum at baseline (10th percentile, 27.5 mL/min/1.73 m
2
), higher hepcidin was associated with a 0.87 g/dL decrease in HGB during follow-up (95 % CI −1.69, −0.05 g/dL,
p
= 0.038). At higher GFR percentiles there was no significant association between baseline hepcidin and HGB during follow-up. Among 90 non-anemic subjects at baseline, 23.3 % developed incident anemia. In subjects with GFR ≤ the median, a higher hepcidin level was associated with an increased risk of incident anemia (at the 10th percentile GFR, HR 3.471, 95 % CI 1.228, 9.810,
p
= 0.019; at the 25th percentile GFR, HR 2.641, 95 % CI 1.213, 5.750,
p
= 0.014; at the 50th percentile GFR, HR 1.953, 95 % CI 1.011, 3.772,
p
= 0.046). Among subjects with GFR at the 75th percentile or above, incrementally higher baseline hepcidin was not associated with increased anemia risk.
Conclusions
Higher hepcidin levels are associated with a decreased HGB and an increased risk of incident anemia, and this association is most significant among subjects with lower GFR.</description><identifier>ISSN: 0931-041X</identifier><identifier>EISSN: 1432-198X</identifier><identifier>DOI: 10.1007/s00467-014-2991-4</identifier><identifier>PMID: 25380788</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Adolescent ; Anemia ; Anemia - blood ; Child ; Child, Preschool ; Chronic kidney failure ; Cohort analysis ; Complications and side effects ; Cross-Sectional Studies ; Enzyme-Linked Immunosorbent Assay ; Female ; Glomerular Filtration Rate ; Hemoglobin ; Hemoglobins - metabolism ; Hepcidins - blood ; Humans ; Infant ; Iron ; Kidney diseases ; Longitudinal Studies ; Male ; Medicine ; Medicine & Public Health ; Metalloproteins ; Nephrology ; Original Article ; Pediatrics ; Physiological aspects ; Prognosis ; Proteins ; Renal Insufficiency, Chronic - blood ; Risk Factors ; Urology</subject><ispartof>Pediatric nephrology (Berlin, West), 2015-04, Vol.30 (4), p.635-643</ispartof><rights>IPNA 2014</rights><rights>COPYRIGHT 2015 Springer</rights><rights>IPNA 2015</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c676t-f6e8d33241407bec01172a075a3d7f05921308412b4dffd42344e7d90e63a19a3</citedby><cites>FETCH-LOGICAL-c676t-f6e8d33241407bec01172a075a3d7f05921308412b4dffd42344e7d90e63a19a3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,780,784,885,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/25380788$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Atkinson, Meredith A.</creatorcontrib><creatorcontrib>Kim, Ji Young</creatorcontrib><creatorcontrib>Roy, Cindy N.</creatorcontrib><creatorcontrib>Warady, Bradley A.</creatorcontrib><creatorcontrib>White, Colin T.</creatorcontrib><creatorcontrib>Furth, Susan L.</creatorcontrib><title>Hepcidin and risk of anemia in CKD: a cross-sectional and longitudinal analysis in the CKiD cohort</title><title>Pediatric nephrology (Berlin, West)</title><addtitle>Pediatr Nephrol</addtitle><addtitle>Pediatr Nephrol</addtitle><description>Background
