[Severe side-effects of treatment with D-penicillamine (author's transl)].

In a 53-year-old woman an acute allergic thrombocytopenia (acute Werlhf's disease) occurred after treatment with D-penicillamine for one month which led to death. In two further patients transitory platelet deficiencies were observed after six and two months which regressed completely in six months and four weeks, respectively. One of the patients had nephrotic syndrome and a retrobulbar neuritis at the same time. Both symptoms were equally transitory and could not be demonstrated five weeks after cessation of therapy. In a further case a lethal Lyell syndrome developed three weeks after therapy was started. These observations show that during D-penicillamine treatment weekly, and later fornightly, blood counts should be performed. In the occurence of thrombocytopenia, leucopenia or anaemia treatments should be stopped; Signs of drug intolerance together with exanthemata should also led to a critical review of the indications and the dosage. D-Penicillamine should not be used when hypersensitivity to penicillin exists or when cell deficiencies have occurred after anti-reheumatic medication. The development of proteinuria should also result in withdrawal of the drug. Therapy with D-penicillamine requires conscientious follow-up urinalyses and blood counts as well as attention to allergic rashes.
