The aim of this study was to evaluate serum levels of the lymphokine interferon-gamma (IFNg) in patients with chronic pulmonary sarcoidosis, and to investigate its value as a predictive marker of clinical response to corticosteroid therapy. Twenty-five patients and 28 age-matched control subjects were studied. All the patients had parenchymal shadows (Stage II or Stage III) and none had clinical evidence of extrathoracic disease. Before therapy, serum IFNg levels were significantly higher in the patient group (p less than 0.001), and 20 (80%) had values above the normal range. After oral treatment with corticosteroids for a median 13 months (range, 3 to 49 months) the levels decreased significantly (p less than 0.01). However, the falls were less pronounced in patients who had a better outcome in terms of achieving complete radiographic resolution and in those who improved in forced vital capacity by greater than or equal to 10%. The prognostic value of the pretreatment serum IFNg was explored, and a significant relationship was found between higher pretreatment levels and lower grades or radiographic abnormality assessed 3 yr after commencement of treatment (p less than 0.01). In addition, the patients who had cleared completely while receiving steroids and remained in remission had significantly higher pretreatment serum IFNg levels than did those with incomplete resolution of parenchymal shadows or radiographic relapses (p less than 0.05). We conclude that elevated levels of circulating IFNg are detectable in most untreated patients with Stage II/III pulmonary sarcoidosis and that patients with the highest levels appear to have a better chance of achieving complete resolution with corticosteroid therapy.
