Introduction: Hepatitis B virus (HBV) infection is a major public health problem in Cameroon. Garoua city is the headquarters of the North Region of Cameroon, where the HBV prevalence is among the highest of the country. The aim of this study was to determine the prevalence of HBsAg carriage and associated factors among persons incarcerated in the Garoua Central Prison. Methods: It was a cross-sectional study conducted from July 1 to July 31, 2023 at the Garoua Central prison. We included all prisoners willing to participate in the study and who gave their verbal consent. We collected data using a pre-established data entry form and we used rapid test for blood screening for HBV surface antigen (HBs Ag) with ELISA confirmation. Data were analyzed using the R® software for Windows. After the univariate analysis, we selected associated variables to HBV infection with p-value p-value was set at 5%. Results: We included 1389 prisoners out of which 97.6% were male. The median age (IQR) of the study population was 28 (23 - 35) years. The median (IQR) duration of incarceration was 12 (6 - 26) months and the mean (±sd) number of incarcerations was 1.24 (±0.6). HBV prevalence was estimated at 14.8% (95% CI: 13.0 - 16.7). Upon uni- and multivariate analysis, no risk factor was significantly associated with viral hepatitis B infection in our study population. Conclusion: The prevalence of Hepatitis B was high in the Garoua Central Prison, but there were no additional risk factors for HBV infection. There is a need to include the Garoua Central Prison and by the way other prisons in the country in the chronic viral hepatitis care program.

Introduction: Portal hypertension (HTP) is a morbi-mortality factor in cirrhotic patients. It is responsible for endoscopic lesions and has digestive hemorrhage as the main complication. The objective of the study was to study the management of endoscopic lesions of portal hypertension in a country with limited resources. Methodology: This was a cross-sectional and analytical study conducted in 04 hospitals in the city of Douala, Cameroon, over a period of 08 years from 1 January 2014 to 31 December 2022. Included were cirrhotic patients with viral hepatitis with endoscopic lesions of PH. The data collected were sociodemographic, clinical, paraclinical, therapeutic and evolutionary. Data analysis was done using SPSS software version 25.0. Logistic regression allowed the search for prognostic factors with a significance threshold of p Results: We included 603 patient records. They were mainly male patients (56.1%) with an average age of 47.6 ± 6.3 years. The Child Pugh score was ranked B in 53.7% of cases. Digestive hemorrhage was the main complication in 66.8% of cases. We had grade 2 esophageal varices in 61.5% of cases. The main treatments were prescription of propanolol (63.3%) and ligation of esophageal varices (53.3%). The average number of ligation sessions was 2.1 ± 1.8 with an interval between sessions of 28 ± 2.8 days. Prevention of rupture of esophageal varices was secondary in 66.5% of cases (n = 452). The rate of hemorrhagic recurrence was 9.3%. Hospital mortality was 15.1%. Recurrence of hemorrhage was associated with PT Conclusion: The management of HTP lesions was based on the prescription of beta-blockers and the ligation of esophageal varices. Factors associated with mortality were hemorrhagic recurrence, low PT and Child Pugh C score.

Introduction: Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease worldwide and its prevalence increases with that of metabolic syndrome and its components. NAFLD is associated with complications such as cirrhosis and hepatocellular carcinoma. Diagnosis is mainly based on liver biopsy, but there are validated non-invasive methods. The purpose of the study was to assess the impact of metabolic steatopathy in patients with metabolic syndrome in Cameroon. Methods: This was a cross-sectional and analytical study conducted over a 6-month period from January 1st, 2019, to August 31st, 2022. Included were patients with metabolic syndrome who had consulted in endocrinology or gastroenterology at Yaoundé Central Hospital, Douala General Hospital and Douala Gyneco-obstetric and Pediatric Hospital. The diagnosis of NAFLD was made on abdominal ultrasound in front of a homogeneous or heterogeneous hyperechogenic aspect of the hepatic parenchyma compared to that of the right renal cortex called “brilliant liver” and fibrosis evaluated through non-invasive scores (Fib4 and NALFD Fibrosis score). Logistic regression by a uni- and multivariate analysis made it possible to search for the associated factors. Results. We included 133 patients. The female sex represented 64.7%. The mean age was 55 ± 9 years. The prevalence of NAFLD was 48.9%. At the evaluation of fibrosis was significant according to FIB-4 and NAFLD fibrosis score respectively in 6.2% and 4.6% of cases. The independently associated factors were Triglyceridemia ≤ 1.5 g/l (OR = 0.33;95% CI [0.11 - 0.95];p = 0.04) and LDL hypercholesterolemia (OR = 2.94;95% CI [1.07 - 8.11];p = 0.036). Conclusion: NAFLD was present in almost half of patients with metabolic syndrome. We had very few patients with significant fibrosis, but it needs to be further evaluated. The associated factors are hypertriglyceridemia and LDL hypercholesterolemia.

Introduction: Helicobacter pylori is a gram-negative bacillus responsible for numerous gastroduodenal pathologies, and this infection is a public health problem. The prevalence of infection with this bacterium remains high in countries with limited resources. Diagnosis relies mainly on numerous invasive and noninvasive methods. The aim of this work was to evaluate the different indirect diagnostic methods using bacterial cultures. Methods: We conducted a cross-sectional and analytical study from January to May 2022 in the gastroenterology departments of Douala General Hospital and Douala Military Hospital. All patients aged 18 years and older who were in the gastroenterology consultation and agreed to participate were included in our study. Sociodemographic, clinical, and paraclinical data were collected. Urease, liquid urea, and culture tests were performed from the specimens obtained by fibroscopy. Serological tests were performed on the blood sample. Results: 101 patients were included, 58 were female and 43 were male, for a sex ratio of 1.3. The mean age was 44.2 ± 16 years. The prevalence of infection was 90.5%, 44.1%, 40.6% and 21.8% for serology, direct microbiological examination, RUT (rapid urea test) and culture, respectively. Comparison of the different tests showed sensitivity and specificity of 67.1% and 64%, respectively, for RUT, 100% and 73.7%, respectively, for direct microbiological examination, and 100% and 14.8%, respectively, for serology. The positive and negative predictive values were 39.5% and 100% for serology, 39% and 85% for RUT, and 55.6% and 100% for direct microbiological examination, respectively. Conclusion: The prevalence of Helicobacter pylori infection depends on the type of test used. Direct examination is more reliable than RUT and serology.

Background and Aims: Diagnostic colonoscopy allows exploration of the colonic mucosa. Indications are multiple. The purpose of this work was to describe the indications and to report the lesions observed during colonoscopy at the General Hospital of Douala. Methods: This was a cross-sectional study with retrospective data collection over a period of 7 years (January 1, 2010 to January 31, 2017). The data collected from the reports were socio-demographic characteristics, indications and lesions observed at colonoscopy. Binary logistic regression allowed us to identify the independent risk factors associated with the presence of tumors and polyps. Results: We included 719 exams. The main indications were rectorrhagia (29.5%), abdominal pain (25.9%) and constipation (17.8%). A colonic lesion was found in 60.1% of cases. A colorectal tumor accounted for 10.3% of cases. Factors independently associated with colonic tumor were complete colonoscopy (aOR: 0.167 95% CI [0.096 - 0.289], p Conclusion: The presence of weight loss, abdominal or rectal mass should motivate the realization of a complete colonoscopy in search of a colorectal tumor. The most observed lesions remain hemorrhoids, polyps and diverticulosis of the colon.

Background: Non-invasive markers which use routine laboratory tests are less expensive and highly needed to assess and stage liver fibrosis in chronic hepatitis B patients in Sub-Saharan Africa. We aimed at evaluating liver fibrosis, using the Aspartate aminotransferase to Platelet Ratio Index (APRI), Fibrosis Index Based on 4 factors (FIB4), and Gamma-glutamyl transpeptidase to Platelet Ratio (GPR) in chronic hepatitis B patients with transient elastography as the reference so as to choose an alternative to transient elastography. Method: We carried out a cross-sectional study using the records of patients who attended the Douala General Hospital and Marie O Polyclinic Douala from 2012 to 2017. Non-invasive tests were compared with Transient Elastography. The Spearman coefficient was used to determine correlation. The sensitivity, specificity, positive predictive values and negative predictive values were used to get the optimal cut-off values. The diagnostic accuracy was estimated by calculating the area under the Receiver Operating Characteristic Curve (ROC). P Results: Of the 243 patient records studied, the median age or interquartile range (IQR) was 35 (29 - 42) years with a male predominance of 73.7%. More than 60% of the study population had normal transaminases. Significant fibrosis was found in 88 (36.2%) patients and 32 (13.7%) patients had cirrhosis. APRI had the best cut-off values and highest area under the ROC Curve, for significant fibrosis and cirrhosis with 0.55 (0.823 95% CI [0.769 - 0.869], P Conclusion: APRI, had the best diagnostic properties to detect liver fibrosis and cirrhosis in patients with Chronic Hepatitis B in Douala. The cut-off values are 0.55 and 0.65 for significant fibrosis and cirrhosis respectively.

Background: Tenofovir (TFV) is widely used to treat patients with hepatitis B virus (HBV) infection. But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration).

Introduction: General anesthesia and antisepsis have made intraperitoneal surgery safer. With the improvement of anesthetic techniques and the development of new surgical approaches, the liver, an organ with high haemorrhagic risks, has become the subject of many successful therapeutic indications. Although widely performed in high-income settings due to a better technical platform, the reverse is true for low-resource settings in Africa where there is little or no report on the anesthetic management of this dreadful surgery. Hence, this study is one of the first from Africa to report on the perioperative anesthetic management and outcome of hepatic resections. Methods: This was a retrospective case series study conducted over four years (2019-2022) through a chart review of all medical and anesthesia records of patients admitted to Douala General Hospital, Cameroon for hepatic resection. We collected socio-demographic, clinical, laboratory and intraoperative data, the estimated financial cost and patient outcomes. Results: Twelve open hepatic resections were performed mainly electively (11/12 cases) for localized hepatic tumours (7/12 cases) on ASA II patients (11/12 cases) with a mean age of 36.5 years and sex ratio of 1.2. Pre-anesthetic consultations were usually done within 24 days before the surgery. General anesthesia maintained with sevoflurane was the mainstay anesthetic technic. Continuous hemodynamic monitoring with an arterial catheter was done. The blood-sparing strategy was based on tranexamic acid, calcium gluconate and controlled hypotension with an intraoperative transfusion rate of 33.33%. The cost of the procedures was well above the minimum wage in Cameroon but relatively cheap compared to the cost in high-income countries. No perioperative death was recorded. Conclusion: Our hepatic resections were managed with satisfactory blood savings, low morbidity and zero perioperative mortality. Overall, this study is the first to provide data on perioperative anesthetic management and outcomes of hepa

Background: the hepatitis B virus infection remains a major public health problem worldwide. It can lead to a liver cirrhosis and/or hepatocellular carcinoma. The World Health Organisation (WHO) has recommended the implementation of generalised vaccination programs against hepatitis B. In Cameroon, this vaccine was introduced in the expanded program on immunization (EPI) in 2005, but few studies have assessed the immune response. Objective: the general objective of this study was to identify factors associated with antibody levels among children aged from 15 to 59 months vaccinated against hepatitis B during the EPI in Cameroon. Method: this was a cross-sectional study carried out from December 2021 to June 2022 in a paediatric centre of Yaoundé (Cameroon). We analysed the antibody level in children vaccinated against hepatitis B within the framework of the EPI. We enrolled children who had received a series of 3 intramuscular doses of hepatitis B vaccine at 6, 10 and 14 weeks after birth. Some children could receive a 4th booster dose between 12 months. The antibody level was assessed by measuring the anti-HBs in such children, aged 15 - 59 months. A good immunization was defined as a serum level of anti-HBs antibody level above 100 IU/mL;a poor immunization, for an anti-HBs antibody level between 10 and 100 IU/mL;and a non-immunization, for an anti-HBs antibody level < 10 IU/mL. Association between explored factors and poor or non-immunization was evaluated through the Chi square test. The significance threshold was defined at p < 0.05. Results: sixty subjects were included in the study with a slight female majority: 31 cases (52%). The average age was 38.5 ± 15.7 months (range 15 - 59 months). We found 32 (53%) cases of good immunization;21 (35%) of poor immunization;and 7 children (12%) with a non-immunization. The only factor associated with poor or non-immunization was the age between 37 - 59 months (p = 0.016). Conclusion: Anti HBs Antibody levels in children vaccinated against hepatitis B virus

Introduction: Gastroduodenal lesions are common in chronic kidney disease (CKD). They are linked to various factors including Helicobacter pylori infection (H. pylori). Few data are available in Africa on H. pylori infection and chronic kidney disease. The aim of this study was to assess the impact of H. pylori infection and to describe the gastroduodenal lesions found in patients with chronic kidney disease. Patients and Methods: A cross-sectional study was conducted, February 1st to May 31st, 2021, at the Douala General Hospital in Cameroon. We included patients with CKD classified as stages 3 to 5 according KDIGO classification, on hemodialysis or not, who agreed to participate in the study. They were matched with a “control” population including patients with normal renal function according to sex and age (ratio 1:2). Patients on antibiotics and/or proton pump inhibitors were excluded. We collected data from CKD patients and from medical records for non-CKD group. Each patient underwent an upper digestive endoscopy and identification of H. pylori using a urease rapid test. Logistic regression was used to identify independent associations for a significance level set at p Results: We included 99 patients including 33 with CKD and 66 control patients. Among patients with CKD, the predominance was male (n = 18/33 or 54.5%). The mean age was 51.2 ± 12.8 years. Arterial hypertension was the first etiology of CKD (n = 13 or 39.4%). The prevalence of H. pylori in patients with CKD was 63.6% versus 37.9% in control patients (p-value = 0.015). The main endoscopic lesions were erosive gastropathy (n = 14 or 42.4%) and erythematous gastropathy (n = 7 or 21.2%). Patients with CKD were 5 times more likely to have H. pylori infection (OR = 5.69;CI 95% 0.14 - 0.82;p = 0.017). Factors associated with H. pylori infection were chronic kidney disease (aOR = 1.02;CI 95% 0.14 - 0.82;p = 0.017) and hemodialysis (aOR = 10;CI 95% 1.08 - 91.9;p = 0.042). Conclusion: The prevalence of H. pylori infection is highe
