Anti 70 kDa heat shock protein antibodies in sera of patients affected by autoimmune and non-autoimmune thyroid diseases.

High prevalence of anti-hepatitis delta virus antibody in chronic liver disease in Somalia.

We have assessed the prevalence of hepatitis delta virus (HDV) infection in people with histologically proven chronic liver disease living in Somalia. Among 104 patients studied (14 with chronic persistent hepatitis, 74 with chronic active hepatitis, and 16 with active cirrhosis), 52 were positive for hepatitis B surface antigen; of these, 26 (50%) carried anti-delta antibodies. HDV infection was detected more frequently in sera from hepatitis B e antigen (HBeAg) negative patients (60.
