BACKGROUND/AIMS: This study aimed at correlating the presence of extrahepatic manifestations with hepatitis B virus (HBV) genotypes in patients with chronic HBV infection. METHODS: This was a national (France), multicenter, retrospective, cross-sectional study. HBV genotypes were determined in 190 patients HBsAg-positive for at least 6 months and documented before any treatment. RESULTS: Patients were aged 42+/-15 years and mainly male (77%). Alcohol intake was high in 6% of them, ALT elevated in 73%; 27% were cirrhotic. All HBV genotypes were found, mainly A (24%), D (29%), C (11%), and E (10%). Thirty (16%) patients had clinical extrahepatic manifestations, mainly sensory-motor deficiency, sicca syndrome, myalgia, glomerulonephritis, and arthralgia-arthritis. Their presence was not related to any epidemiologic, viral (including genotypes) or hepatic factor, but to a higher platelet count (P=0.004). Twenty-nine (15%) patients had biological extrahepatic manifestations, mainly anti-smooth muscle, antinuclear, and anti-nucleosome antibodies. Their presence was related only to anti-HBe antibodies positivity (P=0.007) or elevated platelet count (P=0.003). Carrying precore mutant HBV increased by 2.8 folds the risk to have at least one extrahepatic biological manifestation. CONCLUSIONS: No relationships between HBV genotypes and the presence of extrahepatic manifestations were evidenced in patients with chronic HBV infection.
