Polyarteritis in Children

Abstract

• Polyarteritis was diagnosed in three girls, 9 to 10 years old, by kidney and skin biopsies. They were treated with a combination of prednisone (1.5 to 2 mg/kg) and cyclophosphamide (2 mg/kg) for up to 12 months. The illness was severe in all three, complicated by hypertension, seizures, pulmonary infiltrates, renal failure, or hallucinations. All three patients are alive and well with no or minimal residual symptoms two to three years after therapy was discontinued. The treatment with corticosteroids or with a combination of steroids and immunosuppressive drugs seems to improve the prognosis of polyarteritis considerably. (<i>Am J Dis Child</i>130:534-541, 1976)
