title: [Successful treatment of panarteritis nodosa with low-dose methotrexate therapy].
abstract: We report on a 45-year-old male patient who presented a classic polyarteritis nodosa (PAN). The clinical course extended over 7 years. In spite of 2 years immunosuppressive therapy with azathioprine and methylprednisolone the course was progressive. Low-dose methotrexate therapy was the only treatment that controlled the disease, leading to rapid clinical and histopathological remission. In low concentrations methotrexate acts as an IL-1 inhibitor, and it obviously suppresses the pathogenetic mechanism of PAN.
