Treatment of coccidioidomycosis with ketoconazole: an evaluation utilizing a new scoring system.

The evaluation of the response of patients with coccidioidomycosis to any therapeutic modality is a major challenge. A numerical scoring system was devised to quantitate separately the severity of disease on clinical presentation, the findings on chest film, bone scan, gallium scan, serology and skin test with coccidioidin and spherulin. The scoring system was used to evaluate the response to treatment with ketoconazole of seven patients with infiltrate pulmonary coccidioidomycosis; 20 patients with chronic cavitary coccidioidomycosis; and 40 patients with disseminated coccidioidomycosis. Dissemination included the soft tissue in 15, bone in 15, synovium in 11 and skin in 18. In all categories clinical severity scores improved dramatically. Radiographic scores showed similar improvement in cases of infiltrative pulmonary coccidioidomycosis but showed no change in cavitary coccidioidomycosis. Serology scores improved significantly (-2 or more) in one of seven infiltrative pulmonary cases, three of twenty chronic cavitary cases and twenty-three of forty disseminated cases. Among those with adequate mycology followup, cultures converted to negative in two of three infiltrative pulmonary coccidioidomycosis; seven of fourteen chronic cavitary coccidioidomycosis; and sixteen of twenty-two with disseminated disease. Unfortunately, when ketoconazole was discontinued or interrupted, symptoms recurred in four of twenty (20 percent) with chronic cavitary and ten of forty (25 percent) of disseminated cases. The disease in two patients progressed while on ketonconazole. One of those developed meningitis.
