Anemia is a common feature among patients with chronic renal failure (CRF). Low activity of the erythrocyte enzyme glucose-6-phosphate dehydrogenase (G6PD), which plays a major role in protecting red blood cells against oxidative agents, has been described as one of the contributing factors to anemia in patients with CRF treated with hemodialysis (HD). In this study, blood samples were randomly collected from 65 patients on HD and investigated for G6PD deficiency using the methemoglobin reduction test. The hemoglobin (Hb) concentration, packed cell volume (PCV), red blood cells (RBCs) count and reticulocyte count were determined in all the samples. Our results showed that 39 of 65 patients (60%) on HD had low G6PD activity and 26 (40%) patients had normal activity; 59% of the patients with low G6PD activity were males. The mean Hb, PCV and RBCs counts were lower in patients with low G6PD activity than in those with normal G6PD activity, but the difference was not statistically significant. Likewise, no statistically significant difference was found in the reticulocyte count in patients with low G6PD activity and in those with normal G6PD activity. The low G6PD activity that was found in a large proportion of patients on HD seems to be the result of enzyme inhibition rather than deficiency. No statistically significant difference was found in anemia parameters between patients with and without G6PD deficiency.
