For the severe interstitial pneumonia/pulmonary fibrosis attributed to polymyositis, the patient was started on prednisone, 60 mg daily. After 2 weeks, he had no significant clinical or subjective improvement in his pulmonary status; rather, he felt worse, and he was hospitalized with herpes zoster infection involving his right eye and treated with IV acyclovir. Because of the manifested herpes zoster infection following oral prednisone treatment, the patient declined further corticosteroids and conventional immunosuppressive therapy. He received three infusions of IV immunoglobulin at a dosage of 2 gm/kg monthly for 3 months. Following his last infusion, he clinically improved; his studies demonstrated significant improvement (CK, 327; aldolase level, 10; sedimentation rate, 30; and Dlco, 13.3, or 44% of predicted). The patient declined further treatment and maintenance therapy with immune-modulating agents, including IV immunoglobulin. He was monitored closely at regular intervals, with no evidence of recurrence by objective measurements. At 2 years since his presentation, his room air saturation was 98%, with no desaturation after 6 min of ambulation. His last PFTs demonstrated a Dlco of 16.5, or 55% of predicted (Table 1). He has no functional limitations. His muscle enzymes and inflammatory markers remain normal. An HRCT scan of his chest demonstrated complete resolution of the fibrotic changes and interstitial pneumonia (Fig 2).
