DISSEMINATED INTRAVASCULAR COAGULATION IN PROSTATIC-CARCINOMA TREATED WITH KETOCONAZOLE AND AN ESTROGEN DERIVATIVE

A prostate biopsy was carried out in a 53-year-old male outpatient with disseminated prostatic carcinoma. Two days later, he was admitted with severe acute anaemia (haemoglobin: 48 g.1(-1) and macroscopic haematuria. Biological investigations revealed a disseminated intravascular coagulation (DIC). Symptomatic treatment was undertaken (transfusion of packed red blood cells, platelets, fresh frozen plasma and fibrinogen). However, the patient's condition worsened, and he was admitted to the intensive care unit 48 h later. Despite appropriate symptomatic treatment, the patient's condition continued to worsen. The prostatic origin of this condition was therefore suspected, and anti-androgenic treatment was started on day 9 (1 200 mg.day-1 ketoconazole and 2 000 mg.day-1 sodium fosfestrol). Within 48 h, the patient had began to recover in quite a spectacular manner. Ketoconazole starts blocking steroid synthesis within 4 h of giving it. This treatment can be used until oestrogen therapy starts having an effect (about one week). The low levels of testosterone in this case, before starting treatment, suggest that ketoconazole acted on the DIC by a possible cytotoxic effect on the carcinomatous cells.
