摘要

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.
