These conditions are well known causes of bone marrow hyporesponsiveness and erythropoietin resistance in dialysis patients. The role of iron\u2010deficiency as a cause of hyporesponsiveness under these conditions is not clear. Reticulocyte haemoglobin content (CHr) is one of several iron indices used to determine iron deficiency in dialysis patients. The aim of this study is to evaluate the role of CRP and CHr in iron administration and anaemia management in dialysis patients<\/jats:p><jats:p><jats:bold>Methods:\u2003<\/jats:bold> In 47 haemodialysis patients with ferritin levels of &gt;500\u2003ng\/mL, CRP, CHr, transferrin saturation (TSAT), other markers and erythropoietin dose were evaluated. Patients with CRP\u2003&lt;\u20035\u2003mg\/L (Group A) were compared to patients with CRP\u2003&gt;\u20035\u2003mg\/L (Group B).<\/jats:p><jats:p><jats:bold>Results:\u2003<\/jats:bold> Ferritin levels in the two groups were not different. Weekly erythropoietin was significantly different between the two groups. Group B required an average of 121% more erythropoietin than Group A to maintain similar haemoglobin levels of 11\u201312\u2003g\/dL 36% of Group B had CHr\u2003&lt;\u200329\u2003pg versus 7% of patients in Group A. 39% of patients in Group B also had TSAT\u2003&lt;\u200320% versus 0% in Group A. Group A also had more arteriovenous (AV) fistulae as dialysis access than group B.<\/jats:p><jats:p><jats:bold>Conclusion:\u2003<\/jats:bold> Data indicate that low CHr, similar to low TSAT, could be associated with inflammatory process and erythropoietin resistance, but not necessarily with iron\u2010deficiency. High CRP association with low CHr and low TSAT levels can explain the lack of response to further IV iron therapy. AV grafts, contrary to AV fistulae, are associated with high inflammatory markers and also with a higher erythropoietin requirement.<\/jats:p>","DOI":"10.1111\/j.1440-1797.2006.00676.x","type":"journal-article","created":{"date-parts":[[2006,9,29]],"date-time":"2006-09-29T15:43:13Z","timestamp":1159544593000},"page":"400-404","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Role of C\u2010reactive protein, reticulocyte haemoglobin content and inflammatory markers in iron and erythropoietin administration in dialysis patients"],"prefix":"10.1111","volume":"11","author":[{"given":"MAHMOUD","family":"EL\u2010KHATIB","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HEATHER J","family":"DUNCAN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K SHASHI","family":"KANT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,9,29]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.V13suppl_1s28"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0272-6386(97)90339-5"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0009-9120(96)00010-K"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/clinchem\/48.7.1066"},{"issue":"1","key":"e_1_2_5_6_2","first-page":"s182","article-title":"NKF\u2010K\/DOQI clinical practice guidelines for anemia of chronic kidney disease: Update 2000","volume":"31","author":"NKF\u2010K\/DOQI.","year":"2001","journal-title":"Am.
