[Correlation of growth hormone and aetiology of psoriasis].

Pathological alterations of capillaries, accelerated epidermopoesis, increased rate and extent of metabolism in the psoriatic lesion and first manifestation of psoriasis rarely in the first 20 years of life made us decide to investigate the human growth hormone (STH) in blood serum. In 70 patients suffering from psoriasis we found that the extention of skin lesions was correlated to the STH levels, which were determined every 2 h all over the day. The average STH level in psoriasis was three times as high as average value in the group of 40 controls. Thus, one can conclude that psoriasis is caused by a persistence of STH with individual penetrance.
