UVB Phototherapy and hemodialysis pruritus.

The renal failure-related pruritus is frequent (10-30%) and this frequency increases in dialysed patients (60-80%).

Its physiopathology remains badly known. The prurit is variable in intensity and surface. It predominates on the forehead, the back and the forearms. The skin is normal on it presents non specific lesions. The best treatment would be the renal graft. When it can't be done, phototherapy represents a good therapeutic alternative. We report the experience of our patients from December 1993 to January 2002. The patients could benefit from a steady treatment and be well followed-up. The mean age of our patients was 51 years with a masculine predominance (12 men to 7 women). The mean duration of hemodialysis was 3 years and the one of prurit was 10 months. Between December 1993 and January 2001,

UVB phototherapy with a spectrum was used in 14 cases. After this period a phototherapy with a narrow spectrum was used. The mean dose was 2 Joules with a number of sessions. Eventually, the total body irradiation with UVB was the most regularly effective therapy of the hemodialysed prurit. It allows an important reduction, which is a significant result in comparison with UVA irradiation.
