[Practical considerations of immunoprophylaxis in viral hepatitis].
Hepatitis virus infections belong to the major etiological factors of both acute and chronic liver diseases. During the last years--apart from the passive immunoprophylaxis through the administration of immunoglobulin--safe and efficacious hepatitis vaccines (against hepatitis A and B viruses) has also became available in Hungary. In this review the authors focus on the practical considerations of the immunoprophylaxis of hepatitis viruses. General consensus concerning the clinical use of hepatitis A vaccine has not been accepted, and human immunoglobulin is the only acceptable measure to prevent postexposure hepatitis A virus infection. Hepatitis B immunoglobulin (HBIG) is administered to prevent hepatitis B infection after exposure of HBV-contaminated body fluids and in infants born to HbsAg-positive mothers. Recombinant hepatitis B vaccine has the crucial note in the WHO's program for eradication of hepatitis B. While in the areas of high endemicity the implementation of universal hepatitis B vaccination is recommended, in the countries with low HbsAg-carrier prevalence infants' and/or adolescents' vaccination can offer alternative choices. Prevention of health-care workers against hepatitis virus infection and the vaccination of patients with chronic liver disease are also of great importance. There is also an urgent need to establish multidisciplinary professional cooperation to be able to carry out effectively the WHO's recommendations for prevention of hepatitis B infection.
