High–Dose Pulse Versus Nonpulse Corticosteroid Regimens in Severe Acute Respiratory Syndrome

The treatment of atypical pneumonia, subsequently termed severe acute respiratory syndrome (SARS), is controversial, and the efficacy of corticosteroid therapy is unknown. We have evaluated the clinical and radiographic outcomes of 72 patients with probable SARS (median age 37 years, 30 M), who received ribavirin and different steroid regimens in two regional hospitals. Chest radiographs were scored according to the percentage of lung field involved. Seventeen patients initially received pulse steroid (PS) (methylprednisolone > or =500 mg/day) and 55 patients initially received nonpulse steroid (NPS) (methylprednisolone
