Hypertensive crisis, hepatitis B virus and polyarteritis nodosa in a child.

ABSTRACT

We report on a case of hepatitis B virus-related polyarteritis nodosa (PAN) in a 4-year-old Turkish boy who was first admitted because of severe arterial hypertension. The diagnosis of PAN was provided by conventional renal arteriography and the child was successfully treated with intensive sequential therapy combining short-term prednisone, plasma exchange and interferon-alpha-2b. Nine years later, he had no sign of PAN, normal blood pressure and normal renal function in the absence of any treatment.
