Hepatitis B virus infection and its relation to cardiovascular risk factors such as lipid profile, hsCRP in Korean adults / 대한내과학회지

ABSTRACT

BACKGROUND: Among the recent advances in understanding atherogenesis, the "infection hypothesis" is one of the most compelling but remains controversial. Recent experimental and epidemiologic findings suggest that some infectious agents play a role in the development and promotion of atherosclerosis. But very few data are available on the relation between HBV infection and atherosclerosis. We have investigated the possible association between hepatitis B virus surface antigen (HBsAg) positivity and cardiovascular risk factors including hsCRP in healthy Korean adults. METHODS: In 48,423 healthy subjects, the proportion of seropositive subjects for HBsAg and its association with cardiovascular disease risk factors were evaluated in participants in health screening program. Hepatitis B virus infection status was tested with HBsAg test with IRMA (immunoradiometric method) and serum lipid profiles, hsCRP were tested. RESULTS: Of the 48,423 study subjects, 4.5% were positive for HBsAg, indicating that they were hepatitis B virus carriers. In male, HBsAg positive group showed higher mean values for high density lipoprotein (HDL) and lower values for triglycerides, low density lipoprotein (LDL), total cholesterol. They were statistically significant (p<0.001). In female, HBsAg positive group showed higher mean values for high density lipoprotein (HDL) and lower values for triglycerides (p<0.001). In multivariate analysis of covariance (MANCOVA), adjusted by age and other variables, triglyceride, total cholesterol and low density lipoprotein were inversly associated with HBsAg seropositivity in male while only triglyceride and total cholesterol were inversly associated in female. HBsAg seropositivity and other risk factors including hsCRP level which is markers for inflammation were not correlated(p=0.055, p=0.074). CONCLSUION The result of this study suggest no significant association between hepatitis B infection and hsCRP which is markers for inflammation but possible association with some cardiovascular risk factors such as triglyceride, total cholesterol, HDL, and LDL. Relationship between HBV infection and atherosclerosis has no definitive answer and is disputed issue therefore should stimulate the initiation of further studies to determine whether hepatitis B virus is indeed a causative factor in atherogenesis.
