The prevalence and incidence of hepatitis B in hemodialysis patients in Croatia have been estimated to 1.3% and 0.03%, respectively. HBV infection in dialysis patients is usually asymptomatic, has a prolonged course, and progresses to chronic HBsAg hepatitis in 50% of cases. Some 15%-40% of HBsAg carriers on dialysis will develop cirrhosis, liver decompensation or hepatocellular carcinoma. Strict adherence to the standard infection prevention measures, continuous monitoring of HBV markers in patients on hemodialysis, patient and personnel immunization and hepatitis B treatment in hemodialyzed patients are mandatory. Each new patient in a dialysis center must be tested for HBV markers irrespective of prior immunization. All patients in the center should be routinely screened every 3-4 months. HBV immunization is mandatory for all patients on dialysis. In patients with uremia the anti-HBs antibody production is decreased (antibodies will develop in 50%-60% of cases after immunization). It is recommended to immunize all patients with progressive kidney disease, preferably in the preterminal stage. Hepatitis B therapy is recommended in all patients with biopsy proven chronic liver disease. Patients should be treated with standard interferon alpha and/or lamivudine, or peginterferon alpha monotherapy. Hepatitis B treatment is most important in kidney and/or liver transplant candidates. HBV immunization is obligatory for all hospital personnel who are in close contact with infected patients and infective materials. |
