Polyarteritis Nodosa in a Patient with Type 1 Autoimmune Hepatitis
ABSTRACT Polyarteritis nodosa is a systemic necrotizing vasculitis that affects small- and medium-sized arteries. Liver involvement in patients with polyarteritis nodosa has been described, and ranges from asymptomatic elevation of aminotransferases to hepatic aneurysm rupture. We describe the case of a patient with type 1 autoimmune hepatitis and compensated liver cirrhosis who developed classic polyarteritis nodosa, complicated with cytomegalovirus and repeated urinary tract infections. After a long bedridden hospitalization, the patient's condition was stabilized. She is currently in good health, with well-controlled blood pressure, and stable kidney and liver function. To our knowledge, this is the first case report in the literature with concurrent appearance of both diseases.

ABSTRACT: Hepatitis B virus (HBV)-related polyarteritis nodosa (PAN) is a rare disease whose frequency has been decreasing over the past 10 years. We evaluated 41 patients with HBV-related PAN to determine the circumstances leading to infection, the clinical features of vasculitis, the prognostic factors, and the response to therapy. Most patients were first treated briefly with corticosteroids, and all were included in 2 nonrandomized prospective therapeutic trials of an antiviral agent (35 patients with vidarabine, 6 patients with interferon-alpha 2b) and plasma exchanges. The mean duration of follow-up was 69.6 +/- 44.8 months. At the end of the study, 21 (51.2%) patients had seroconverted to anti-HBeAb and 10 (24.4%) also had seroconverted to anti-HBsAb. In all, 23 (56%) patients no longer expressed serologic evidence of HBV replication. All 33 (80.5%) patients still alive at the end of follow-up recovered from PAN. Nineteen also recovered from HBV infection and were considered to be cured; 13 patients had persistent HBV infection and were considered to be in clinical recovery; and 1 patient was in remission, maintained with steroid therapy. Eight patients died during the study period; 3 deaths were directly attributable to PAN. HBV-related PAN is an acute disease, occurring shortly after infection and sharing the characteristics of classic PAN. It is not an antineutrophil cytoplasm antibodies (ANCA)-mediated vasculitis. The outcome was good for patients treated with short-term steroid therapy, antiviral agents, and plasma exchanges. We propose this protocol as the first treatment for HBV-related PAN, because it surpasses the conventional treatment with corticosteroids and cyclophosphamide, which facilitates viral replication and the development of chronic HBV infection.Medicine 10/1995; 74(5):238-53. · 4.87 Impact Factor
