35 patients attending a hospital dialysis unit were questioned for the presence and severity of pruritus. Attention was given to skin anomalies and loss of hair. In all patients the serum vitamin A level was determined. Although all of them showed an increased serum vitamin A level, no correlation could be found between the vitamin A content and the presence of pruritus.
