          Abstract

          The incidence of chronic hepatitis B in Germany is approximately 0.5 %. Data regarding knowledge about HBV, prevention behaviour and treatment adherence in patients with chronic HBV are scarce. In this prospective study 201 consecutive patients with CHB infection were studied from a large urban academic outpatient clinic at the University Medical Centre in Hamburg. Patients were interviewed with a questionnaire that contained 47 questions covering social demographic dates, knowledge about HBV, treatment adherence and prevention. The success rate of interviews was 100 % with free translation service offered. 20.4 % of the CHB patients were born in Germany, but the majority of the patients were immigrants (80.6 %). 51 % of the patients had a good, 34 % a moderate and 15 % a poor knowledge about HBV. 89 % of the patients knew that HBV can be transmitted through blood contacts, but 34 % believed that inadequate hygienic conditions and 24 % that food products may transmit the virus. 96 % of the patients had knowledge about the existence of an HBV vaccine. Furthermore, 82 % considered a vaccination of all persons in the household important. Despite the knowledge of the existence and importance of a vaccine, only 61,7 % of the 300 affected children/siblings of HBV-positive family members were vaccinated. However, the child vaccination rate was significantly higher among patients with knowledge about the protective effect of the vaccine (p < 0.001), the free of charge vaccination program for children up to 18 years (p < 0.001) and higher school education (p < 0.001). Migrants with poor German language skills had lower knowledge scores (p < 0.001) and showed lower vaccination rates (p = 0.016) compared to immigrants with good German language skills. 43 % of all patients were treated with nucleot(s)ide analogues with a median treatment duration of 2 - 5 years. 65 % of these patients declared to never have missed a dose and 27 % missed less than one dose per month. 90 % of the patients tolerated the antiviral drugs very well and between patients with or without side effects there was no significant difference in quality of life. Chronic hepatitis B in Germany is characterised by awareness problems and language barriers. More attention is needed for HBV-infected immigrants in the form of multilingual information about CHB and awareness campaigns. © Georg Thieme Verlag KG Stuttgart · New York.
