Nodular prurigo is a distressing disease which is difficult to treat.
Two patients with severe nodular prurigo were treated with cyclosporin
for periods of 36 and 24 weeks, respectively, using doses of 3-4.5 mg
/kg per day. In both cases there was a reduction in the severity of pr
uritus after 2 weeks of treatment, In one patient there was a consider
able, although incomplete response, and in the other almost complete r
esolution of the disease was achieved. The improvement was maintained
throughout the treatment period, and the drug was generally well toler
ated, although in one patient there was a rise in serum creatinine dur
ing treatment, which later returned to normal.
