HBsAg serum level (quantification) may be useful for managing hepatitis B virus (HBV) infection patients. However few studies especially in Africa have evaluated the association between HBsAg serum level and liver fibrosis severity. The objective of this study was to estimate the correlation between HBsAg serum level and liver fibrosis severity with treatment naive chronic hepatitis B patients in Cote d’Ivoire. Methodology: It is a prospective study covering from February 1st, 2014 to April 30st, 2015 at Centre Hospitalier et Universitaire de Yopougon and a private medical office in Abidjan, Cote d’Ivoire. Inclusion criteria for patients were: HBsAg positive, known HBeAg status, serum HBsAg levels, serum HBV DNA levels, complex serum markers and absence of HCV, HDV, or HIV co-infection, drinking more than 30 g/day for men and 20 g/day in women over 10 years, metabolic disease and/or hepatic overload. Pearson’s Chi-square test (r2), Anova, Spearman, T-Student, Pearson’s (r) correlations and Mann Withney’s Test were carried out as appropriate. A p value < 0.05 was taken as significant. Results: We recruited, 105 patients (77 men) of whom the medium age was 39.01 ± 9.72 years. Predominant hepatitis B viral genotype was E (93%). Less than 10% patients had an inactive HBV in HBeAg-negative. Patients had an average high HBsAg serum level (mean 12111.2 ± 10617.4 IU/ml) as well as the one viral load (mean 4.4 e7 ± 7.5 e7). Serum ALAT levels averaged at the upper limit of normal value. The average liver fibrosis score was 0.34 ± 0.22 and the degree of viral activity was 0.19 ± 0.20. Half of our patients had no fibrosis (35.24%) or had mild fibrosis (20.95%). No significant association was observed between HBsAg serum level and patient age (p = 0.3994), genre (p = 0.8075) or serum ALT levels (p = 0, 0787). In multivariate analysis, there’s a significant correlation (r = 0.239, p = 0.014) between HBV DNA levels and HBsAg serum level. There’s a significant correlation (r = 0.92

Open Journal of Gastroenterology 2013年第4期3卷 237-240页

Aims of the Study: 1) Determine the Prevalence of Hepatitis B virus (HBV) infection in children (contact subjects) of chronic Hepatitis B surface antigen (HBsAg) carrier subjects (index subjects);2) Search for factors associated with HBV infection in these children. Patients and Methods: Retrospective-crosssectional study (January 5th, 2006 through December 31st, 2012). Studied parameters: biological and clinical characteristics of index subjects;Prevalence of HBsAg and Hepatitis B core antibody (HBcAb) in their children. Search for the HBV infection associated factors in the children (univariate analyses through Chi-square or Fisher’s exact test;multivariate analysis through a backward logistic regression). Results: Our 44 subjects’ median age was 43.1 ± 7.49 years and 88.6% of them lived with a spouse. Average number of children per index subjects was 2.3 ± 1.1. Our 92 children’s median age was 9.3 ± 4.55 (ranging from 1 to 15 years), and 43 (44.8%) were vaccinated against HBV. HBV infection prevalence was 24% (23/96 of which, 4 were HBsAg positive and 19 HBcAb positive subjects without HBsAg). Independent factors associated with HBV infection in children of index subjects were HBV DNA for index subjects >2000 IU/ml (OR = 11.5;p = 0.001), existence of HBV in two parents (OR = 7.9;p = 0.03) and absence of HBV vaccination in the children (OR = 30.9;p = 0.003). Conclusion: Immunization coverage for children of index subjects was insufficient, especially before the introduction of HBV vaccine into the enlarged vaccination program. Outside vertical transmission, those children were more exposed to HBV intrafamilial transmission risk when they were not immunized against HBV, when both parents were infected and when HBV viremia in index subjects was higher than 2000 IU/ml.

Cirrhosis is the cause of a high rate of death in hospitals. The aim of this research was to estimate the incidence of mortality and identify the risk factors associated with cirrhosis patients in hospital in Cote d’Ivoire. Methodology: It is a retrospective study covering from January 1st, 2002 to December 31st, 2011 at Centre Hospitalier et Universitaire de Yopougon in Abidjan. We concerned the cirrhosis patients that have been followed at the hepatology and gastroenterology department. Survival was estimated by the Kaplan-Meier curve and comparison of survival curves by the log-rank test. The multi-varied analysis of the survivals has been achieved with the Cox proportional Hazard regression. A p value < 0.05 was taken as significant. Results: We recruited, 221 patients (135 men) of whom the medium age was 59 ± 15.12 years. Among those patients, 34.5% were classified as Child Pugh C and 52.94% Child Pugh B, 19.45% suffered from digestive hemorrhage, 26.5% suffered from renal deficiency, 47% suffered from hepatic encephalopathy and 10.7% from hyponatremia. The median overall survival of patients was 0.50 person-months. The variables that were significantly associated to a reduction of survival were hepatic encephalopathy (p = 0.0029), spontaneous ascitesfluid infection (p = 0.0208), hyponatremia (p = 0.0434) and stage Cof Child- Pugh score (p = 0.046). Conclusion: The incidence of mortality in cirrhotic patients hospitalized in Abidjan is high. Pejorative prognostic factors were essentially hepatic encephalopathy, spontaneous ascites fluid infection, hyponatremia and stage C of Child-Pugh score.

The aim of our study was to assess in our context, the efficacy of Rifaxim in improving the symptoms of irritable bowel syndrome particularly in its diarrheal (IBS-D) or mixed (IBS-DC) component and therefore assess its impact on patients’ quality of life. Patients and methods: This was an uncontrolled, non-comparative prospective cohort study of a single group of patients. Patients recruitment was done in two University Hospitals for 6 months (September 2015-February 2016). Were included ambulatory patients, male or female, aged 18 - 75 years, with diarrheic IBS (IBS-D) or mixed IBS (IBS-DC) diagnosed according to Rome III criteria and who agreed to participate in the study. Each patient received 400mg Rifaximin × 2/d for 15 days. The overall assessment of the efficacy of treatment at D15 (end of treatment) and D30 (2 weeks post-treatment) was the primary criterion of judgment. The statistical tests used were the Chi-square test and Fisher’s exact test for the qualitative variables and Student’s test for the quantitative variables. Results: A total number of 30 patients (16 women) with an average age of 44.5 ± 13.9 years were included. The overall assessment of symptoms by the patient with the Likert scale found 28 (93.3%) patients, 12 (40%) patients and 10 patients (33.3%) for a scale ≥2 at D0, D15 and D30 respectively. The assessment of the intensity of pain or abdominal discomfort found at D0, D15 and D30 respectively: 27(90%), 13(43.4%) and 6(20.1%) patients who had an EVA score > 2. The mean score for Francis to assess the improved quality of life was 247.1 ± 97.4 at D0, 99.8 ± 63.1 at D15 and 128.8 ± 70.6 at D30. Conclusion: There is a good overall improvement of symptoms in our patients suffering from IBS-D or mixed (IBS-DC) on Rifaximin with improvement of the quality of life.
