[Diabetes and viral hepatitis B].

The author emphasizes the fact that diabetics are also in the Czech Republic a group with a high risk of infection with viral hepatitis type B (VHB), i. e. in diabetics a higher prevalence of acute VHB is found, a higher prevalence of HBsAg and anti-HBs, and in diabetics chronic sequelae acute hepatitis are more frequent. The author recommends active immunization against VHB and to focus attention on the group most at risk, i. e. to examine in the Czech Republic all diabetics treated with insulin for the presence of HBsAg and anti-HBs and to immunize subsequently against VHB negative subjects from this group.
