The aim of this study was to document the dynamics of HBV viral load during the follow-up of chronic hepatitis B patients at the Saint Camille Hospital in Ouagadougou (HOSCO) from 2017 to 2021. This descriptive retrospective study was carried out in the Hepato-Gastro-Enterology Department of HOSCO and focused on patients who were undergoing treatment for chronic viral hepatitis B. A total of 260 cases of chronic hepatitis B were included in the study. The most affected age group was 21 to 30 years, accounting for 48.08% of the cases. Lifestyle factors included alcohol consumption (3.08%) and tobacco use (2.69%). Major risk factors for transmission included lack of vaccination (98.46%), family history of HBV infection (68.00%) and engagement in high-risk activities (28.00%). Patients requiring treatment were prescribed Tenofovir 300 mg tablets. FibroScan<sup>®</sup> showed the presence of stage F3-F4 fibrosis (2.14%) and S3 steatosis (13.33%). After one year of follow-up, 6.92% of patients achieved an undetectable viral load with normalized transaminase levels. The majority of other patients had a detectable viral load but below 20,000 IU/mL. The prevalence of viral hepatitis B remains significant worldwide. Although effective and well-monitored treatment can lead to undetectable viremia, prevention remains the most effective strategy for successful management of this disease.展开更多

All patients received conventional doses of lamivudine and adefovir dipivoxil, telbivudine, entecavir dispersible tablets, or entecavir tablets for 96 wk. Patients who used other antiviral drugs or antitumor and immune regulation therapy were excluded. Patients were stratified into three groups according to their viral DNA load at 24 wk: < 10 IU/m L(group 1), 10-103 IU/m L(group 2), and > 103 IU/m L(group 3). Correlations of 24-wk DNA load with HBe Ag negative status and HBe Ag seroconversion at 96 wk were analyzed. Receiver operating characteristic curve analysis was used to test the predictive value of the HBV DNA load at 24 wk for long-term response.RESULTS The rates of conversion to HBe Ag negative status and HBe Ag seroconversion rates were 53.7% and 51.9%, respectively, in group 1; 35.21% and 32.39% in group 2; and 6.38% and 6.38% in group 3. The receiver operating characteristic curves for the three subgroups revealed that the lowest DNA load(< 10 IU/m L) was better correlated with response at 96 wk than a higher DNA load(10-103 IU/m L). Nested PCR was used for amplifying and sequencing viral DNA in patients with a viral DNA load > 200 IU/m L at 96 wk; resistance mutations involving different loci were present in 26 patients, and three of these patients had a viral DNA load 10-103 IU/m L at 96 wk. CONCLUSION Hepatitis B viral DNA load at 24 wk of antiviral treatment in patients with chronic hepatitis B is a predictor of the viral load and response rate at 96 wk.展开更多
