Abstract
Increased levels of circulating immune complexes (CIC) were demonstrated by the Clq [a fragment of complement component 1] binding assay in 22 (27%) of 81 patients with recurrent polyserositis. The prevalence of increased CIC was significantly higher in Jewish patients of North African origin (42%) than in subjects of other ethnic groups (6%). North African patients also manifested an increased familial incidence, earlier onset of symptoms and a higher frequency of arthritis. There was no correlation between increased CIC levels and disease activity. The immune response of North African patients probably differs from that of subjects of other ethnic groups; this difference is possibly genetically determined.
