Constrictive pericarditis in procainamide-induced lupus erythematosus syndrome

Abstract

A rare case of constrictive pericarditis in procainamide-induced lupus erythematosus syndrome is reported. After 6 months of procainamide therapy fever, pleuritic chest pain, arthralgia and muscle soreness developed in a 47 year old man. These symptoms were soon followed by the onset of acute pericarditis and rapidly accumulating massive pericardial effusion. After withdrawal of procainamide therapy and administration of corticosteroids in large doses, there was marked subjective improvement and rapid reduction in pericardial effusion. However, constrictive pericarditis with massive leg edema and ascites developed 6 weeks after admission as corticosteroid therapy was gradually discontinued. These manifestations subsided after pericardiectomy was performed.
