Objective To investigate the relationship between hepatic steatosis and virological markers in patients with chronic hepatitis B (CHB ) during immune clearance (IC ) phase.Methods Pathology proven CHB patients in IC phase were collected from the Liver Center of the First Affiliated Hospital of Fujian Medical University from January 2009 to October 2016 .Patients were divided into non-to mild fatty liver (F0 -F1) group and moderate to severe fatty liver (F2 -F4) group according to the liver steatosis degree .The relationship between liver steatosis and virological markers in serum was compared .The measurement data were analyzed using independent sample t test ,and the count data were analyzed by chi-square test .Results A total of 298 patients were included ,including 237 males (79 .5%) and 61(20 .5%) females ,and the average age was (32 .4 ± 10 .3) years old .The 23 .5%(70/298) of these patients had liver steatosis .A total of 273 (91 .6%) cases were in F0-F1 group ,and the remaining 25 (8 .4%) cases were in F2 -F4 group.The patients in F2 - F4 group had higher body mass index ([25.90 ± 2.70] vs [21 .68 ± 2.90] kg/m2) ,serum triglyceride ([1.52 ± 0.77] vs [1.11 ± 0.55] mmol/L) and cholesterol ([4 .88 ± 1 .15] vs [4 .33 ± 0 .92] mmol/L) than F0-F1 group ,and the differences were all statistically significant (t= -7 .007 ,-2 .667 ,and -2 .751 ,respectively ,all P<0 .05).In addition , the serum levels of HBsAg and HBV DNA in F2 -F4 group were also significantly higher than F0 -F1 group (t= -3 .291 and -2 .831 ,respectivelt ,both P<0 .01).According to the grading of inflammation and fibrosis ,the differences of HBsAg and HBV DNA levels between F0 -F1 group and F2 -F4 group were statistically significant only in patients with more severe inflammation (t= -2 .738 and -2 .135 , respectively ,both P<0 .05) or less severe fibrosis (t= -2 .258 and -2 .333 ,respectively ,both P<0 .05).Conclusion Among CHB patients experiencing immune clearance ,serum HBsAg and HBV DNA levels are positively correlated with the severity of hepatic steatosis ,and this phenomenon is closely related to the degree of liver inflammation.
2.Epidemiology and clinical outcome of chronic hepatitis B virus infection and metabolic dysfunction
Journal of Clinical Hepatology 2024;40(3):453-456
Chronic hepatitis B virus (HBV) infection is a worldwide public health issue and a leading cause of liver fibrosis, liver cirrhosis, liver failure, and primary liver cancer in China. The incidence rate of nonalcoholic fatty liver disease (NAFLD) is gradually increasing with the improvement in the living standards of people and the changes in dietary structure. Population-based studies have found that HBV infection can influence the development of NAFLD, but the mechanism remains unknown. Hepatic steatosis can also influence the expression of HBV serum pathogenic indicators, and its combination with NAFLD and other metabolic dysfunction diseases can increase the risk of liver fibrosis, liver cirrhosis, and liver cancer. Chronic HBV infection is closely associated with metabolic dysfunction, and more studies are needed in the future to better understand related mechanisms, so as to provide a theoretical foundation for clinical diagnosis and treatment.

Objective To investigate the relationship between Toxoplasma gondii (T.gondii) infection and metabolic syndrome (MS).Methods A total of 20 577 patients who received serum test of anti-T.gondii IgG antibody in the National Health and Nutrition Examination Survey ( NHANES) of the United States from 2009 to 2014 were collected to analyze the clinical features of anti-T.gondii IgG antibody positive patients , and to compare metabolic related indicators in the antibody IgG positive and negative groups .The independent sample t-test, chi-square test, and logistic regression analysis were used to explore the risk factors of MS . Results A total of 2 746 participants were positive for the T.gondii antibody (13.34%), with a higher prevalence of male (14.44%vs 12.27%, χ2 =15.99, P<0.01).Meanwhile, the prevalence of T.gondii increased with age and body mass index (BMI) (χ2 =979.98 and 50.85,respectively, both P<0.01).Among the 2 191 patients with MS, 449 (20.49%) patients were positive for T.gondii.While 2 297 (12.49%) patients were anti-T.gondii positive in 18 386 non-MS patients.The difference was statistically significant (χ2 =78.504, P<0.01).Age (t=-37.37), BMI (t=-4.28), glycosylated hemoglobin (t=-11.81), fasting blood glucose (t=-9.38), triacylglycerol (t=-6.32), cholesterol (t=-7.16), serum uric acid (t=-5.25) and serum creatinine (t=-7.69) in the seropositive group were all higher than those in the seronegative group (all P<0.01).After adjusting for age and gender , the prevalence of T.gondii was an independent risk factor for MS (odds ratio [OR]=1.147,P=0.023).Conclusions BMI, blood lipids, blood uric acid and blood glucose are significantly increased in patients with T.gondii infection.T.gondii infection is an independent risk factor for MS.
