The impact of early and brief corticosteroids ontheclinical course of primary pulmonary coccidioidomycosis

Objective: Primary pulmonary coccidioidomycosis can often be associated with hypersensitivity symptoms treatable with a short course of palliative corticosteroids. Long-term use of corticosteroids is a known risk factor for severe or disseminated infection but the effects of short-term use are not known. Methods: A retrospective review was conducted of immunocompetent patients with acute pulmonary coccidioidomycosis who received systemic corticosteroids for relief of coccidioidal-related symptoms. Age- and sex-matched controls were also reviewed. Predetermined end-points were assessed. Results: Seventy-four patients met inclusion criteria for the corticosteroid-treated group, and 74 controls were identified. Cumulative corticosteroid (prednisone-equivalent) doses were 10mg→3,600mg (mean=206mg; median=120mg). Corticosteroids were prescribed most commonly for rash 43/74 [58%] or asthma/wheezing/cough 30/74 [41%]. Coccidioidal-related hospitalization occurred in 19 patients in the corticosteroid group vs. 22 in the control group (P=58). Coccidioidal-related symptoms resolved within a mean of 19 weeks (median=8 weeks [range=2-208 weeks]) vs. 32.3 weeks (median=8 weeks [range=1-1040 weeks]) in the corticosteroid and control groups (P=38). Relapse of symptoms occurred in 12% of both groups (. P>.99). Extrapulmonary dissemination occurred in 3% vs. 4.0% (. P>.99) in the corticosteroid and control groups, respectively. Conclusion: This study found no adverse effects of short-term corticosteroid therapy for early symptomatic treatment in acute pulmonary coccidioidomycosis.
