Abstract: | The present study was aimed to evaluate erythrocyte folate and the iron levels in diabetes and hypertension patients treated with/without hemodialysis. The effects of erythropoietin and iron treatment as well as vitamin supplementation on measured parameters were considered. The 67 controls consisted of healthy subjects (n = 22), hypertensive subjects (n = 22), and diabetic subjects (n = 23) without any renal disorder. According to primary renal disorders, the patients undergoing hemodialysis (n = 68) were classified into four groups as diabetic nephropathy, hypertensive nephropathy, reflux nephropathy or interstitial nephritis, and renal insufficiency depending on other causative factors. The mean value of erythrocyte folate levels of all patients undergoing hemodialysis was higher than the healthy control group (P < 0.05). Erythrocyte folate levels in hypertensive and diabetic nephropathy patients were higher than their own hypertensive or diabetic controls and also healthy controls (both, P < 0.05). Serum iron levels of all subgroups in hemodialysis patients were found to be similar with healthy controls (all, P > 0.05). The only significance observed within the subgroups was between diabetic controls and diabetic nephropathy patients (P < 0.05). None of the treatment or supplementation of erythropoietin, iron and vitamin affected erythrocyte folate levels (all, P > 0.05). The increase in erythrocyte folate status of patients with end stage renal diseases might be the result of sum or individual effects of causative factors such as renal pathology, compensation mechanism against renal anemia, or routine folate supplementation. |
