Penicillamine-induced bullous dermatoses.
The successful therapeutic use of D-penicillamine (DPA) has been hindered by its many adverse effects. Autoimmune bullous syndromes are among the less common adverse DPA reactions; they are not dose dependent and appear late in the treatment of diseases of altered immunity, most often rheumatoid arthritis. The majority of the DPA-induced bullous syndromes belong to the pemphigus spectrum, usually pemphigus foliaceus or erythematosus, have a lower prevalence of demonstrable tissue-fixed or circulating antibodies than spontaneously occurring pemphigus, display abnormal direct immunofluorescent patterns, and have a generally favorable prognosis. However, many cases do exhibit a full-blown chronic disease, unaffected by DPA withdrawal. DPA-induced cicatricial pemphigoid is a severe disease of both mucous and cutaneous involvement with a prognosis similar to the spontaneous disease. Cases of DPA-induced epidermolysis bullosa acquisita and DPA-induced bullous pemphigoid were not sufficiently substantiated by immunofluorescence or immunoprecipitation criteria.[1]References
