title: Cryoglobulinemia and hepatitis B markers in North African Jews with Raynaud's disease.
abstract: Mixed cryoglobulinemia was discovered in 11 of 20 patients with Raynaud's disease. Hepatitis B surface markers were found in 10 of these patients with cryoglobulinemia. All patients with cryoglobulinemia were female, and 10 were of northern African origin. This study indicates that, in a population with a high prevalence of hepatitis B infection, mixed cryoglobulinemia is an important etiologic factor in Raynaud's disease.
