Distribution of serum proteins, red cell enzymes and haemoglobins in vitiligo.

125 Sudanese patients suffering from vitiligo were investigated for the distribution of serum proteins (haptoglobins and transferrins), red cell enzymes (acid phosphatase, 6-phosphogluconate dehydrogenase, phosphoglucomutase and glucose-6-phosphate dehydrogenase) and hemoglobins. The results were compared with the published healthy population series investigated for the same genetic markers. There was no significant association with any of the marker systems in vitiligo except glucose-6-phosphate dehydrogenase. An excess deficiency of this enzyme was observed in vitiligo patients compared to the control series.
