RESUMO
Objective@#To investigate the prevalence and risk factors of non-alcoholic fatty liver disease(NAFLD) in patients with chronic hepatitis B(CHB) receiving antiviral treatment.@*Methods@#The cross-sectional study included 3 477 cases with CHB who received antiviral therapy. The prevalence of NAFLD was investigated, and then the risk factors were screened and analyzed by stepwise regression method in CHB patients with NAFLD as the dependent variable and the related influencing factors as independent variables.@*Results@#The prevalence of NAFLD was 24.1% in CHB patients who received antiviral therapy. After adjusting for age and gender, central obesity (OR: 7.44, 95%CI: 6.06 ~ 9.14), hypertension (OR: 1.74, 95%CI: 1.51 ~ 2.20), and triglyceride (OR: 1.52, 95%CI: 1.18 ~ 1.96) were positively associated with NAFLD, and cirrhosis was negatively associated with NAFLD (OR: 0.42, 95%CI: 0.34 ~ 0.53). Patients with long-term antiviral therapy had increased risk of NAFLD.@*Conclusion@#A significant proportion of CHB patients receiving antiviral therapy have suffered from NAFLD. Therefore, CHB patients receiving long-term antiviral treatment should pay more attention to the prevalence of NAFLD.
RESUMO
<p><b>OBJECTIVE</b>To evaluate the changes in the renal function of patients with chronic hepatitis B (CHB) receiving adefovir dipivoxil (ADV) or telbivudine (L-DT) monotherapy.</p><p><b>METHODS</b>This retrospective analysis involved 101 patients with CHB and liver cirrhosis receiving either ADV or L-DT monotherapy for 52 weeks. Serum creatinine, estimates of glomerular filtration rate (eGFR), and the percentage of patients with eGFR≥90 ml·min(-1)·1.73 m(-2) at week 52 were compared with the baseline data between the two groups.</p><p><b>RESULTS</b>The mean changes of CR at week 52 from baseline were +0.05 mg/dl in ADV group and -0.12 mg/dl in L-DT group, showing a significant difference between the two groups (P=0.000). No patient was found to have an elevation of creatinine over 0.50 mg/dl. The median change of eGFR at week 52 from baseline differed significantly between ADV and L-DT groups (-4.09 vs+18.32 ml·min(-1)·1.73 m(-2), P=0.000). Ninety-two percent (12/13) of the patients with baseline eGFR<90 ml·min(-1)·1.73 m(-2) shifted to eGFR ≥90 ml·min(-1)·1.73 m(-2) after 52 weeks of L-DT treatment, as compared to 38% (3/8) in ADV group. The proportion of patients with eGFR≥90 ml·min(-1)·1.73 m(-2) in L-DT group increased from 76.36% (42/55) at baseline to 94.55% (52/55) at week 52, while that in ADV group decreased from 82.61% (38/46) at baseline to 78.26% (36/46). The constituent ratios of eGFR at different levels were similar at baseline (P=0.443) but significantly different at week 52 between the two groups (P=0.015).</p><p><b>CONCLUSION</b>L-DT treatment is associated with a renoprotective effect in patients with CHB, but the mechanism remains unclear.</p>
