Most knowledge about chronic hepatitis B virus (HBV) infection is based upon studies in high-endemic areas with one or two predominant genotype(s). The aim of the study was to describe clinical characteristics of a heterogeneous genotypic HBV patient population in a low-endemic European country.
Data from HBV patients currently followed in a Danish university hospital and affiliated regional clinics were reviewed in accordance to genotype status.
Of 540 HBV patients, 462 (86%) were of non-Danish ethnicity originating from 43 different countries. HBV genotype was known in 37% of the patients: A (11%), B (25%), C (25%), D (37%) and E (2%). Logistic regression analysis of pre-treatment data among genotype A-D patients receiving nucleos(t)ide analogue (NA) therapy revealed a decreased HBeAg rate by age (OR = 0.93; CI: 0.89-0.97; p
