Coccidioidomycosis: Evaluation of Parameters Used to Predict Outcome with Amphotericin B Therapy

A literature review of case histories describing the use of amphotericin B for the treatment of disseminated coccidioidomycosis was performed to detect parameters that were predictive of therapeutic outcome. Several factors were significantly different between patients who were well during prolonged follow-up versus those with active or recurrent disease: 1) mean complement fixation (CF) titer before treatment was lower in patients who were well; 2) well patients had a greater magnitude fall in CF titer during the amphotericin B therapy; 3) mean CF titer after amphotericin B treatment was lower in patients who were well; and 4) patients with a positive coccidioidin skin test before therapy were more likely to be well at 6 months. There was no correlation between total amphotericin B dose or duration of therapy and therapeutic outcome.
