PERIARTERITIS NODOSA

Ten cases of periarteritis nodosa have been histologically diagnosed during a 3‐year period, nine of them by biopsies. Most of the patients had gastrointestinal and cardiac symptoms, together with fever. The BSR was high in nine cases, and in all ten patients serum electrophoresis revealed hypalbuminaemia. The γ‐ and α2‐globulin levels were increased in many cases. Six patients were anaemic. Proteinuria was present in six cases. All the patients were treated with corticosteroids. Seven patients were alive after 5 years, and five after 10 years.
