[Cholestatic jaundice induced by D-penicillamine and oral steroid contraceptive in progressive systemic sclerosis (author's transl)].

A 25-year-old woman with progressive systemic sclerosis was treated with D-penicillamine. (DPA) 30 days after starting therapy cholestatic jaundice was observed. Moreover, for two years she has taken the pill. Both drugs were discontinued, the jaundice disappeared and the laboratory findings of liver became normal. A rechallenge of D-penicillamine after 9 months induced no reaction. An underlying chronic liver disease before cholestasis could be excluded by liver biopsy. Allergic cutantests and lymphocyte transformation test with D-penicillamine and penicillin gave normal results. The frequency of cholestatic jaundice caused by DPA-therapy is discussed and the possible pathomechanism analyzed.

Transverse leukonychia following chemotherapy in a patient with Hodgkin's disease.

Nail changes often represent diagnostic hallmarks for a variety of systemic diseases. The awareness of drug-induced nail injuries is important in order to avoid unnecessary diagnostic activities. We observed a 21-year-old female patient with Hodgkin's lymphoma, who developed transverse leukonychia of all fingernails associated with polychemotherapy.

Dapsone-induced photodermatitis in a patient with linear IgA dermatosis.

Dapsone (4, 4' diaminodiphenylsulfone) is an efficient antiinflammatory agent. Its therapeutic use may result in a variety of adverse effects. The most frequent unwanted reactions are hemolytic anemia and methemoglobinemia. By oral route dapsone is mainly metabolized to monoacetyldapsone (MADDS) and hydroxylamine dapsone (DDS-NOH). We report a 76-year-old female patient with linear IgA dermatosis who developed a dapsone-induced photosensitivity 8 weeks after initiation of sulfone therapy. She showed a widespread erythematous eruption in UV-exposed skin area. After clearing of skin lesions the photopatch test revealed positive reactions to dapsone, MADDS and DDS-NOH. Dapsone-induced photosensitivity to date has been described only in leprosy patients. We demonstrate for the first time that this adverse reaction is not restricted to leprosy and that dapsone metabolites may also contribute to the mechanism of photosensitivity like the parent sulfone. Dapsone-induced photosensitivity is a rare, not dose-related adverse effect of the sulfone and can also occur in patients with inflammatory skin disorders.
