[Interferon in chronic polyarthritis. Positive effect in clinical evaluation].

During the last two years, 80 patients with definite chronic rheumatoid arthritis were treated with interferon-gamma. Considerable improvement in the clinical picture occurred in 58, with pain decreasing rapidly and lastingly or even disappearing. Even in largely immobile patients the ability to walk and general mobility were nearly fully restored. The treatment was well tolerated in 74 patients. As the substance is administered subcutaneously it is suitable for out-patient treatment.
