dc.description.abstractBackground. In this study, our aim was to evaluate the effect of postdialysis administration of parenteral L-carnitine supplementations on hematological parameters and also on weekly requiring dose of the recombinant human erythropoietine (rHuEPO) in hemodialysis (HD) patients. Material and Methods. The stable 34 patients (17 male, 17 female) were enrolled in the study who were on rHuEPO therapy and a regular maintenance HD program at 5 h, three times a week with bicarbonate dialysate and with biocompatible membranes in HD Center of Medical Faculty Hospital in University of Dicle. rHuEPO was administered subcutanously at 80- 120 U/kg/week. The patients were divided into two groups: Group 1, rHuEPO therapy (n = 17) and Group 2, rHuEPO therapy + L-carnitine (n = 17). L-carnitine (L-carnitine ampul, Santa Farma) 1 g was injected postdialysis intravenously via venous route of the dialytic set, three times a week. The patient's hemoglobin (Hgb), hernatocrit (Hct), serum iron (Fe+2), total iron-binding capacity (TIBC), transferrin saturation index (TSI), and serum ferritin (Fer) levels were followed during the 16-week period. The weekly requiring doses of rHuEPO and hematological parameters of patients were recorded at the beginning of the study, at 8 weeks, and at 16 weeks of the study period. Results. In group I (n = 17, 13 female, four male), the mean age was 38.8 +/- 12.1 years, mean period time on HD therapy was 18.1 +/- 14.9 months, and mean KIN value was 1.48 +/- 0.28. In group 2 (n = 17, 13 male, four female), the mean age was 48.1 +/- 15.4 years, mean period time on HD therapy was 34.4 +/- 23.0 months, and mean KIN value was 1.29 +/- 0.20. The hematological parameters of the groups were found as follows: in group 1, Hgb: 7.9-10.8 g/dl, Hct: 25.3-32.5%; in group 2, Hgb: 10.2-11.8 g/dl, Hct: 30.6-35.4%, respectively (p<0.05). The target Hgb/Hct values were achieved at the end of the study in both groups. Both groups were the same according to their serum Fe+2 markers (p>0.05). But unlike serum Fe+2 markers, there were significant differences on weekly requiring doses of rHuEPO therapy between groups. While in group 1, the mean weekly requiring dose of rHuEPO was 6529 U/week (120 U/kg/ week) at the beginning of the study, and maintenance weekly requiring dose of rHuEPO was 3588 U/week (66 U/kg/week) at the end of the study, in group 2, they were 4882 U/week (80 U/ kg/week), and 1705 U/week (28 U/kg/week), respectively. According to these values, the total reduction in weekly requiring dose of rHuEPO was 45% in group 1, and 65% in group 2; the net gain was 20% in group 2 (p<0.05). Conclusions. If other factors related to anemia are excluded, the postdialysis parenteral L-carnitine therapy can be considered in selected stable patients, which may improve anemia and may reduce the weekly requiring dose of the rHuEPO and also be cost-effective.en_US
