[Periarteritis nodosa associated with hepatitis B virus. 42 cases (author's transl)].
HBs antigen was detected by immunodiffusion or radioimmune assay in the blood of 19 out of 42 patients with periarteritis nodosa examined between 1970 and 1978. Histological or biochemical signs of hepatitis were present in 6% of HBs--positive patients and 1% of HBs-negative patients. The incidence of clinical symptoms was similar in both groups, except for multiple neuritis, which was much more frequent in HBs-positive patients (89%) than in HBs-negative patients (52%; p less than 0.001), suggesting a close relationship between neuritis and HBs and HBs antigen. There was a negative correlation between myalgias and skin lesions and the presence of the antigen. The prognosis of periarteritis nodosa was similar in both groups. The course of the disease seemed to be more prolonged in HBs-positive patients, but there was no significant difference in mortality rate.
