Coccidioides immitis infections in bones and joints.

Coccidioides immitis infections of bones and joints pose difficult problems in diagnosis and treatment. To evaluate further the diagnosis and treatment of this disease, a retrospective review was conducted of 24 patients with 44 separate skeletal lesions of C. immitis infection, as determined by positive culture. Patients treated with combined medical and surgical treatment are more likely to have a successful outcome than those treated with medical therapy alone (p less than 0.005). Although immunosuppression did not appear to prevent a satisfactory response to therapy, patients with a high complement fixation titer (greater than or equal to 1:128) were more likely to fail to respond to medical therapy alone (p less than 0.01).
