The treatment of tuberculous pericarditis.

Twenty-seven patients with clinically primary tuberculous pericarditis were treated with prolonged chemotherapy consisting of intermittent doses of streptomycin and daily doses of paraminosalicylic acid or isoniazid. Twenty-one patients did well and were symptom-free six months to three years later. Five, one of whom died, developed constrictive pericarditis. Another died of widely disseminated tuberculosis.
