Background: Anorexia is a common disorder in patients treated with regular haemodialysis and is a contributing factor to malnutrition. The aim of this study was to evaluate the effectiveness of megestrol acetate, an appetite stimulant used in cancer patients, as a treatment for anorexia in dialysis patients. Material and method: In 2009, 16 patients in our haemodialysis unit, three with diabetes mellitus, were treated with megestrol (160 mg/day single dose) for anorexia defined according to a Likert scale of appetite. The schedule and dialysis dose were not changed during the study. Results: In the third month of treatment there was, in the overall group, an increase in dry weight (60.8 vs 58.9 kg, P<.01), concentration of albumin (4.02 vs 3.8 g/dl, P<.05), in creatinine concentration (9.73 vs 8.26 mg/dl, P<.01), and protein catabolic rate (1.24 vs. 0.97 g/kg/day, P<.0001). Non significant variations in the concentration of haemoglobin, erythropoietin dose, and lipid concentrations were found. One patient with diabetes mellitus had to increase the dose of insulin and two other patients suffered mild hyperglycaemia. Megestrol acetate did not suppress the secretion of pituitary sex hormones, but in 3 of 10 patients studied inhibition of ACTH secretion was found. The response was not homogeneous: one patient did not respond and reduced his dry weight, in 5 the weight gain was minimal (less than 1 kg) and in the remaining ten the response was good, with an increase in dry weight ranging between 1.5 and 5.5 kg. Conclusions: Megestrol acetate can improve appetite and nutritional parameters in patients treated with periodic haemodialysis who report anorexia. Megestrol acetate may induce hyperglycaemia and inhibit the secretion of ACTH in some patients. These side effects should be assessed when administering this treatment.
