Authors report on the effect of reduced glutathione parenterally administered on the anemic status in patients suffering from chronic renal failure and undergoing hemodialysis. Twenty patients were studied for 180 days and were divided into two age- and sex-matched groups. The first group (10 patients) received placebo, the second group (10 patients) received the treatment (1,200 mg of reduced glutathione). Reduced glutathione and placebo were given for 120 days in a randomized double-blind fashion and the following measurements were performed : red blood cells reduced and oxidized glutathione, plasma reduced and oxidized glutathione, hematocrit, hemoglobin, reticulocytes, serum iron, transferrin, indirect bilirubin, urea, creatinine, calcium, phosphate, parathyroid hormone and alkaline phosphatase. In the treated group, during the supplementation period, there was an increase in the levels of red blood cells and plasma reduced glutathione, hematocrit and hemoglobin and a concomitant decrease in plasma oxidized glutathione and reticulocytes with a maximum effect on the 120th day of therapy. In the placebo-treated group there were no significant variations of the parameters considered during the study period. When the therapy, on patients undergoing treatment, was terminated there was a drop in the analyzed parameters, which fell to pretreatment values at the subsequent controls. These findings seem to indicate that reduced glutathione could represent a useful drug in the treatment and management of anemia in patients affected by chronic renal failure.
