title: B cell activation in patients with active procainamide induced lupus.
abstract: Cellular immune abnormalities have been described in asymptomatic patients receiving procainamide therapy, but not in patients with active procainamide induced lupus. We tested patients with active procainamide lupus for evidence of T or B cell activation similar to that observed in idiopathic lupus. Symptomatic patients had a significant increase in spontaneous IgG synthesis, but T cells bearing activation markers were not significantly different from age matched controls. Our results demonstrate that patients with active procainamide lupus have evidence for B cell activation, similar to idiopathic lupus.
