The objective of this study was to determine the epidemiological and diagnostic profile of chronic carriers of hepatitis B virus seen for gastroenterology consultations in Parakou, Republic of Benin. Patients and Methods: This was a cross-sectional and descriptive study with retrospective data collection. Patients seen for gastroenterology consultations from January 1, 2017 to June 30, 2021 at the Regional Teaching Hospital of Borgou/Alibori (CHUD-B/A) and having been diagnosed as chronic carriers of hepatitis B virus were included. A minimum initial assessment was required to be included. The minimum sample size was calculated with Schwartz formula. The variable of interest was the detection of HBsAg twice and at least 6 months apart. The other variables studied were sociodemographic, clinical and paraclinical data. The data collected were analyzed using SPSS 17 software. Results: A total of 2786 patients were seen for gastroenterology consultations, including 1126 (40.4%) HBsAg-positive patients. Among them, 417 patients met the inclusion criteria and were the subject of the present study. The average age of the patients was 34.8 ± 10.5 years. Two hundred and forty-seven patients (65.7%) were male, representing a sex ratio of 1.9. The discovery of positive HBsAg status was made during systematic screening in 231 patients (55.4%). Scarifications were noted in 373 patients (89.4%). Asthenia was reported in 184 patients (44.1%). Co-infections with human immunodeficiency virus, hepatitis C and D viruses were 0% (0 in 92), 2.8% (4 in 146) and 14.3% (2 in 146), respectively. During the initial assessment, 274 patients (65.7%) were sero-negative for chronic HBeAg infection, 21 (5%) had clinically significant fibrosis including 16 (3.8%) at the stage of cirrhosis and 7 patients (5.4%) had hepatocellular carcinoma. Conclusion: In Parakou, chronic hepatitis B virus infection is common and affects young people with a male predominance. Asthenia is a non-specific symptom and the most reported by the patients. Around 5 out of 100 patients are seen for consultations at the stage of complication. Emphasis must be placed on early detection and subsidy for pre-therapeutic assessment.展开更多

To investigate the influence of HLA-DRB1 alleles and HBV genotypes on inberferon-α therapy for chronic hepatitis B. METHODS： HLA-DRBI＊03, ＊07, ＊09,＊12, ＊15 alleles were determined using polymerase chain reaction/sequence specific primer （PCR/SSP） technique in 126 patients with chronic hepatitis B and 76 normal control subjects in Shandong Province, and HBV genotypes were determined by nested-PCR analysis using type-specific primers in 126 patients. RESULTS： The positivity of HLA-DRB1＊07 allele in chronic hepatitis B group was significantly higher than that in normal control group （X^2 = 6.33, P〈0.025, RR = 2.37）. Among the 126 patients, genotype B was found in 38 （30.2%）, genotype C in 69 （54.8%）, and mixed genotype （B＋C） in 19 （15.0%）, genotypes D-F were not found. Among the 46 DRB1＊07（＋） patients, 7 were responders and 39 were non-responders among them （X^2 = 6.71, P〈0.05）. The positivity of HLADRB1＊07 and prevalence of HBV genotype C were significantly higher in non-responders than in responders. CONCLUSION： High positivities of HLA-DRB1 ＊07 allele and HBV genotype C are closely associated with the lower response to interferon-α therapy for chronic hepatitis B.展开更多
