Chronic kidney disease (CKD) is defined as kidney damage or glomerular filtration rate (GFR) <60 mL/min/1.73 m2 for 3 months or more.End stage renal disease corresponds to stage 5 chronic kidney disease with glomerular filtration rate <15 ml/min/1.73m2, all these patients require hemodialysis.Anemia of chronic disorders is a common normochromic or mildly hypochromic anemia that occurs in patients with chronic kidney disease.It is characterized by a reduced serum iron and iron binding capaci ty and normal or raised serum ferritin with adequate iron stores. The main cause of anemia is deficient erythropoietin synthesis. Blood loss is also a major contributory factor. Hepcidin plays a key role as mediator of anemia of inflammation.Aim of the study1 - To assess the types of anemia in end stage renal failure.2 - To compare the inflammatory parameters including hepcidin, ferritin, C - reactive protein and erythrocyte sedimentation rate between the two vascular accesses of hemodialysis (double lumen and arteriovenous fistula).Materials and methods This case control study was conducted at Al - Hayat center for hemodialysis in Al - Karama hospital, Baghdad, Iraq over 3 months from 1 November 2013 to 31 January 2014. The study populations consist of 60 [III]patients (44 males and 16 females). All patients were adult with documented end stage chronic kidney disease stage 5 on repeated hemodialysis with different durations of illness (1 month - 10 years).Hemodialysis patients were also divided into two groups depending on the vascular access of hemodialysis (double lumen and arteriovenous fistula).The following data were analyzed for all patients : Age, gender, history of hypertension and diabetes mellitus, causes of renal failure, vascular access, duration and frequency of hemodialysis. Complete blood counts, blood film and reticulocyte percentage by auto analyzer machine. Blood urea, serum albumin, serum creatinine, and transferrin saturation percentage, serum hepcidin, ferritin, C - reactive protein by clinical chemistry analyzer. erythrocyte sedimentation rate Twenty normal healthy individuals (age and sex matched) had been included as a control group in this study. All were subjected to the same investigations of the patients.ResultsThe vascular access of hemodialysis was ʺarteriovenous fistulaʺ in (61.7%) of the patients and "double lumen" in (38.3%) of them. The mean duration of hemodialysis was (18.6 ± 2.5) months (range : 1 month - 10 years), high proportion (28.3%) of the patients were on hemodialysis for a duration of 11 - 15 months.There was a significant decrease of absolute lymphocyte count, red blood cell count, hematocrit, hemoglobin and platelets count in patients than controls, but there were insignificant differences for total white blood cell count, absolute neutrophil count and mean corpuscular volume.Also there was a significant increase of red cell distribution width levels in patients than controls (14.8 ± 1.9 vs. 13.3 ± 1.6 respectively), p<0.05.According to the levels of hemoglobin, anemia was reported in 95% of the 60 end stage renal disease. Anemia of chronic disorders was the most frequent type of anemia (45%) among the patients, iron deficiency anemia was found in only (11.7%) while combined anemia was found in (25%), and others who had not any type of previous types of anemia (13.3%). No significant difference was observed between anemic and non - anemic patients according to the vascular accesses of hemodialysis.The mean serum level of hepcidin for patients was (186.1± 28.4 ng/ml) and for controls was (4.7 ±0.9 ng/ml) with a significant difference between both groups. The mean serum ferritin level of the patients (280.8 ± 53.1 ng/ml) was significantly higher than controls, (83.6 ± 14.5). The mean serum C - reactive protein level was higher in patients than control, (8.6 ± 1.1 vs. 3.0 ± 0.2 mg/l) respectively, furthermore, the mean erythrocyte sedimentation rate level was higher in patients (42.3 ± 4.7 mm/1st hr.) than that of controls (6.2 ± 0.8).There was no significant association between levels of hepcidin, hemoglobin, ferritin, C - reactive protein and erythrocyte sedimentation rate of the patients with the duration of hemodialysis. There was no significant difference in the mean levels of hepcidin, ferritin, C - reactive protein and erythrocyte sedimentation rate of the patients according to the vascular accesses of hemodialysis, while there was a significant difference regarding the hemoglobin level. The mean C - reactive protein of patients with serum ferritin level ≥ 800 ng/ml was (16.5 ± 4.2 mg/L) and for those with serum ferritin level < 800 ng/ml it was (7.6 ± 1.1 mg/L), however, the difference
