The involvement of general practitioners in the early detection of viral hepatitis B and C must be paramount. The objectives of this work were to assess GPs’ knowledge, attitude and practice with regard to screening for viral hepatitis B and C. We carried out a cross-sectional analytical study among GPs recruited by simple random sampling from the list of GPs in the city of Brazzaville. The judgement criteria were knowledge and practice of screening for viral hepatitis B and C, assessed according to a Likert scale divided into 3 categories: very good, good and bad. One hundred and twenty-one general practitioners were included, including 48 women and 73 men, with a sex ratio of 1.52;the average age was 33 years;52.89% of them worked in the private sector with an average period of activity of 4 years. The majority of the doctors had a good knowledge (69.42%) and a bad practice (56.20%) of screening for viral hepatitis B and C. The duration of activity was the factor linked to knowledge of viral hepatitis B and C (p = 0.006) while age was the factor linked to the practice of screening for viral hepatitis B and C (p = 0.0366). In conclusion, in Brazzaville, general practitioners’ knowledge of screening for viral hepatitis B and C is good in general, but the practices are poor and require targeted in-service training.

Objective: assess the knowledge, attitudes, and perceptions of Brazzaville residents on colorectal cancer and its screening. Population and Methods: a CAP-type cross-sectional study was conducted from June 1 to October 31, 2022, with 803 workers approached at their place of service. Information was collected using a questionnaire administered to participants. The variables studied concerned knowledge, attitudes, and perceptions about colorectal cancer. SPSS software, along with Chi-square and Fisher tests, was used for data entry and analysis. Odds ratios were calculated to determine the strength of the association between variables. Results: The average age of the participants was 33.5 ± 10 years, with a sex ratio of 0.9. There were 231 health workers. The main sources of information were health personnel (78.2%) and the internet (52.6%). The site of the pathology was known to 87% of participants. About 40% identified age, genetic predispositions, and a diet rich in animal fats as risk factors. No signs of the disease were known by 50% of the participants. Colonoscopy was known as a screening method by 40% of participants. Seventy-five percent were willing to participate in a CRC awareness campaign, but only 5% agreed to a screening colonoscopy, although 96% recognized its usefulness. Overall, the level of knowledge was insufficient in 70.4% of cases;attitudes were adapted in 55.7% of cases, and perceptions were adapted in 97.3% of cases. Factors influencing knowledge included young age (p = 0.006), a good level of education, being a healthcare worker, and high socio-economic level. Conclusion: colorectal cancer and its screening are poorly understood by the population. Awareness activities must be organized to improve knowledge and promote screening and early diagnosis of CRC.

Objective: Describe the epidemiological and paraclinical aspects of HP infection in hepatitis B virus carriers. Population and Method: This was a descriptive cross-sectional study running from January 1 to August 30, 2019, a period of 8 months. It took place in the Hospital Centers of the two major cities of Congo (Brazzaville and Pointe-Noire). The target population of our study consists of patients carrying HBV under antiviral treatment or not. Patients aged at least 18 years and consenting with a biological and morphological assessment were included. We did not include in our study patients taking or having taken antibiotics and/or PPIs less than 4 weeks ago. We excluded all patients who did not deposit fresh stools and those in whom stool extraction could not be done manually. The variables studied covered sociodemographic, clinical and paraclinical aspects. Data entry was done using Excel 8.0 software. Statistical analysis was carried out with SPSS 20.0 software. Results: During our study, we included 169 patients. The frequency of HPAG in the stools of HBV carriers in our study population was 63.9% (n = 109). Male patients represented 69% (n = 75) and female patients represented 31% (n = 34). The average age of the patients is 43.92 ± 13.51 years with extremes of 18 years and 80 years. Concerning profession, unemployed patients and those working in the private sector were the most represented in respectively 28.4% (n = 31) and 22.9% (n = 25) without statistical link. Households comprising between 4 - 10 people and the use of public latrines were the risk factors most represented in respectively 69% (n = 75) and 88% (n = 96) without statistical link. Clinically, hepatomegaly and signs of portal hypertension were most represented in 53% (n = 58) and 47% (n = 51). Biologically, HBV DNA was detectable in 60.5% of cases (n = 66).

Introduction: Viral hepatitis B is the most formidable and confusing of all viral hepatitis, given its cirrhogenic and carcinogenic potential. The objective of the study is to characterize the molecular profile of hepatitis virus B in northern Congo. Materials and Methods: This was a descriptive and cross-sectional study that was carried out between January and September 2014, that is 9 months, in the establishments of the National Center for Blood Transfusion (CNTS) of the 4 departments of the north of the Congo. Epidemiological, serological and molecular variables (HBsAg, HBV DNA, genotypes and subtypes) were studied. The HBs antigen was searched by rapid test and confirmed by ELISA. For all positive donors, conventional and specific gene extraction and amplification techniques were performed for the identification of genotypes and subtypes from the serum. Results: A total of 892 donors were included. The average age was 35.36 ± 12.36 years with extremes ranging from 18 to 65 years old. The sex ratio (M/F) was 3.3. The prevalence of HBV was 8.6%. The viral DNA of HBV was amplified in 83.1%. Four genotypes were found: E (40.6%), A (3.1%), B (3.1%) and C (1.6%). Two cases of co-infection were identified: E/A (15.6%) and B/C (1.6%). Subgenotypes A1, B2 and C1 were highlighted. Conclusion: The prevalence of HBV is high, HBV infection remains a major public health problem for blood donors in Congo. Genotypes E, A, B, C as well as subtypes A1, B2, C1 have been identified in northern Congo.

In the absence of interventional endoscopy, the treatment of upper digestive haemorrhages (HDH) at Brazzaville University Hospital is essentially medicinal. The objective of this work was to identify the risk factors for HDH mortality at Brazzaville University Hospital by conducting a retrospective prognostic case-control study over a period of 2 years, from January 2017 to December 2018. The 180 patients included in the study for an HDH were divided into 2 groups according to their evolutionary modality: deceased patients (cases) and non deceased patients (controls). The mortality risk factors were studied by logistic regression. Mortality related to upper digestive haemorrhages was 36.6%;the risk factors for death were age between 30 and 60 years with a (OR: 9.79;95% CI [1.24 - 76.83];p = 0.003);male sex (OR: 2.03;95% CI [1.03 - 4];p = 0.0393);late consultation beyond 24 hours (OR: 6.30;95% CI [2.12 - 18.72];p = 0.0009), blood transfusions (OR: 3.5;95% CI [1.66 - 7.40];p = 0.0001). Protective factors were haemoglobin greater than 7 g/dL (OR: 0.28;95% CI [0.14 - 0.54];p = 0.0001);treatment with proton pump inhibitors (OR: 0.36;95% CI [0.15 - 0.84];p = 0.0191). In conclusion, the reduction of the still high mortality rate in our country requires taking into account the identified risk factors and the acquisition of endoscopic haemostasis equipment.

Objective: Study of the frequency of anemia, its characteristics and its relationship with different epidemiological, diagnostic and prognostic parameters of cirrhosis. Patients and methods: This was a retrospective descriptive study from January 2016 to December 2019 in the Gastroenterology and Internal Medicine department at the Brazzaville University Hospital. It concerned all cirrhotics hospitalized during the study period and presenting anemia. The epidemiological, diagnostic, and prognostic data studied were collected from medical records. The characteristics of anemia on the blood count were defined based on WHO values. The information collected was entered and processed with Excel 8.0 and EPI data 3.1 software. The Pearson chi2 test at the significance level ≤ 5% was used to compare the results. Results: We collected 102 files of cirrhotic patients during the study period. There were 63 men and 39 women, a sex ratio of 1.6. Among these patients, 77 presented anemia, i.e., a frequency of 75.5% with a male predominance (57.2%). Anemia increased without a significant relationship with age and was more severe in young female subjects (42.8%). The normochromic normocytic character was the most observed (52%). Anemia was more frequent in post-hepatitic cirrhosis, representing 67.5% of cases of anemia. It worsened during digestive bleeding, with the abundance of ascites and the severity of hepatic encephalopathy (p > 0.05). It was significantly associated with the drop in prothrombin level (63.6%), hypoalbuminemia (64.9%), and the Child-Pugh score (p < 0.05).
