Background: Tuberculous peritonitis often presents with nonspecific symptoms that can lead to diagnostic challenges, particularly when manifesting as peritoneal pseudocysts. This study highlights the clinical complexity and diagnostic approach of tuberculous peritonitis presented as a pseudocyst in an immunocompetent adult, an atypical scenario that is rarely documented., Case Presentation: We report a detailed case of a 41-year-old man presenting with abdominal distension, pain, and significant weight loss over four months. Abdominal CT showed a peritoneal pseudocyst, initially misdiagnosed due to its resemblance to more common abdominal pathologies. The diagnosis of tuberculous peritonitis was confirmed through histopathological analysis. Additionally, a systematic literature review was conducted to identify and analyse similar cases, focusing on clinical presentations, diagnostic methods, and patient outcomes. Our patient exhibited classic symptoms of abdominal TB but was unique due to the absence of prior ventriculoperitoneal shunting, a common factor in similar cases. Our literature review found that such presentations typically result in diagnostic delays averaging five months, complicating patient management and outcomes. This review also underscores the importance of considering tuberculosis in the differential diagnosis of peritoneal pseudocysts, particularly in TB-endemic regions., Conclusion: This case and review emphasize the need for high clinical suspicion and prompt investigation of tuberculosis in patients presenting with atypical abdominal symptoms and pseudocysts. Improved diagnostic strategies, including early use of imaging and pathological evaluations, are essential for timely diagnosis and management, thereby improving patient outcomes in suspected cases of extrapulmonary tuberculosis., (© 2024.

Background and Aims: Treating Helicobacter pylori  infections has become a major challenge due to increased antibiotic resistance. The aim of this study was to investigate the efficacy and tolerability of the main standard regimens recommended for H. pylori eradication in Bukavu, Eastern of the Democratic Republic of Congo., Methods: The study enrolled patients with evidence of H. pylori infection in histological examination or serology testing combined with a positive fecal antigen test. As first-line treatment, patients were randomized to either a 10-days (OAC-10) or a 14-days (OAC-14) regimen, employing a combination of omeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg twice daily. In case of failure, a second line regimen was evaluated and included two others protocols: OAC-10 regimen + levofloxacin 500 mg (OAC-10+) and the bismuth-based therapy (pantoprazole + bismuth salt + metronidazole + tetracycline) during 10 days. Our primary endpoint was H. pylori eradication and secondarily, the compliance and adverse effects were also evaluated., Results: A total of 179 patients were enrolled. The eradication rate was 79.2% and 80.5% with the OAC-10 and OAC-14 regimen, respectively ( p  = 0.796). Adverse effects were significant higher in the OAC-14 group than in the OAC-10 group (36.5% vs. 57.8%; p  < 0.001). On the other hand, the compliance rate was slightly higher in the OAC-10 group (97.9% vs. 91.6%, p  = 0.052) while clinical improvement was almost similar in both groups. Regarding the second line regimen, the bismuth-based therapy ( n  = 18) seemed to show a better response with 100% of eradication rate and 100% of clinical improvement., Conclusion: The classic 10-days triple therapy seems to be as effective as the 14-days regimen while having in addition a good tolerance. Apart from cost issues, the bismuth-based therapy seems to be a very good alternative in case of first-line treatment failure., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

Background and Aim: The coronavirus disease 2019 (COVID-19) pandemic was a priority public health problem because of its high mortality rate. This study mainly aimed to determine factors associated with a poor outcome in COVID-19 hospitalized patients in South-Kivu, an eastern province of the Democratic Republic of the Congo (DRC)., Methods: This observational study retrospectively evaluated medical records of patients consecutively admitted for probable or confirmed COVID-19 between May 01 and July 31, 2020 at the Hôpital Provincial Général de Référence de Bukavu (HPGRB), a tertiary hospital located in South-Kivu. A binary logistic regression model was performed to determine the predictors of mortality., Results: A total of 157 hospitalized COVID-19 patients aged 57.7 (13.2) years were included in this study. Male gender (69.4%), older age (52.9%), medical history of diabetes (38.2%), and arterial hypertension (35.1%) were the most frequent risk factors. Most patients presented with fever (73.3%), cough (72.6%), and dyspnea (66.2%). Overall, 45.1% of patients died. Intrahospital mortality was significantly associated with advanced age [odds ratio, OR (95% confidence interval, CI) = 2.34 (1.06-5.38)], hypoxemia [OR (95% CI) = 4.67 (2.02-10.77)], hyperglycemia [OR (95% CI) = 2.14 (1.06-4.31)], kidney failure [OR (95% CI) = 2.82 (1.4-5.68)], hyperleukocytosis [OR (95% CI) = 3.33 (1.67-6.66)], and higher C-reactive protein (CRP) levels [OR (95% CI) = 3.93 (1.93-8.01)]. After adjustment for various covariates, only higher CRP levels [OR (95% CI) = 3.23 (1.23-8.5)] and hyperglycemia [OR (95% CI) = 2.5 (1.02-6.11)] at admission were independently associated with mortality., Conclusion: Hyperglycemia and marked inflammatory syndrome were the major predictors of poor outcomes in patients hospitalized for COVID-19 in South-Kivu. These two factors should be quantified at hospital admission to establish the patient's prognosis., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

Background and Aims: Hepatitis C virus (HCV) infection and diabetes mellitus (DM) are two frequent diseases in the Democratic Republic of the Congo (DRC) and several studies seem to show a link between the two diseases worldwide. However, no study has evaluated this link in our country. The present study aimed at determining the seroprevalence of HCV in diabetic patients as well as associated risk factors., Methodology: A multicenter cross-sectional study allowed us to sample diabetic patients in two diabetic healthcare centers of Bukavu city in the eastern part of the DRC, from December 2020 to December 2022. A questionnaire was submitted to the diabetic patients to collect sociodemographic data, anamnestic data on risk factors for HCV infection, and clinical data on DM. These factors were analyzed based on anti-HCV serological results., Results: Among the 180 selected patients, 19 (10.6%) were tested positive for anti-HCV antibodies. After multivariate analysis, the identified factors influencing these outcomes were male sex (adjusted odds ratio [aOR]: 3.5, p  = 0.027), dental extraction (aOR: 7.6, p  = 0.001), and living in a privileged environment (aOR: 0.29, p  = 0.03). The factors related to DM such as the type, the disease duration, or the usual type of treatment did not influence the serological results., Conclusion: This study shows that HCV seroprevalence in diabetic patients is very high compared with the general population. This suggests combined screening and management policies in this population., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.

Background: The World Health Organization's (WHO) 2030 goal of eradicating Hepatitis B and C viruses must also include HIV co-infected children. However, data on the prevalence of this condition are lacking in the Democratic Republic of Congo (DRC), which is considered as one of the countries with high-prevalence of these viruses. The need to assess the extent of this co-infection in the children of this country is therefore important in order to capitalize on efforts to improve prevention and management of both infections., Methodology: This is a comparative cross-sectional study conducted from February 04, 2015 to September 03, 2019 at 14 General Reference Hospitals with a pediatric HIV management programme in South Kivu province. The study compared the frequency of hepatitis B (HBV) and C (HCV) markers and factors associated with these two viruses in two equal groups: HIV-positive and HIV-negative children. The data were analyzed using the SPSS version 20.0 software and the significance level was set at p-value less than 0.05., Results: The study involved a total of 594 children, 297 of whom were HIV-positive and 297 negative. HBsAg was found in 8.7% of HIV-positive patients and 0.7% for HCV antibodies. On the other hand, among the HIV-negative patients, the proportion of HBsAg was 0.7% but no cases with anti-HCV antibodies were detected. HIV status increases by 14 times the risk of co-occurring with HBV [OR 14.1 (95% CI: 3.33-60.2); p < 0.001] and this risk is not apparent for HCV (p = 0.297). Multivariate logistic regression showed that history of jaundice in the family (aOR:4.19;95% CI: 2.12-11.59), recent hospitalization (aOR:10.7;95% CI: 6.69-17.2), surgery (aOR: 3.24;95% CI: 1.18-8.92), piercing (aOR: 4.26;95% CI: 1.70-10.7) and transfusion in the last 6 months (aOR: 2.69;95% CI: 1.55-4.67) were significantly associated with higher risk of being HBV- HIV co-infected., Conclusion: This study investigated the importance of hepatitis viral co-infections in HIV-positive children in South Kivu. Particular attention should be paid to prevention and early detection of these co-infections in this population., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Helicobacter pylori ( H. pylori ) is the common etiology of gastric tumors. This study aimed to evaluate the risk factors associated with H. pylori infection in the eastern part of the Democratic Republic of the Congo (DR Congo), where these tumors seem to be more frequent than in its western part., Patients and Methods: Between January and December 2021, the authors conducted a multicenter case-control study in three hospitals in Bukavu City involving 90 individuals with dyspeptic complaints. Risk factors for H. pylori infection were assessed in a participant interview and H. pylori status from stool antigen detection., Results: Among the risk factors assessed, only history of H. pylori in the family and the habit of adding salt to already-seasoned food were found positively associated with the risk of H. pylori infection (adjusted odds ratio: 7, 95 CI: 2.742-17.867; P <0.0001 and 2.911, 95% CI: 1.010-8.526; P =0.048, respectively). On the other hand, low-temperature food storage seems to be protective with a negative association (adjusted odds ratio: 0.044, 95% CI: 0.009-0.206; P =0.0001)., Conclusion: This study demonstrated again the importance of lifestyle-related factors on the risk of acquisition of H. pylori . These findings call for preventive interventions for this group of individuals., Competing Interests: None.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2023 The Author(s).

Background: In low resource settings in sub-Saharan Africa healthcare workers (HCW) have a high risk of contracting hepatitis B infection. Vaccination of HCWs is to protect them from acquisition of hepatitis B from patients., Objective: To evaluate the hepatitis B virus (HBV) serological and vaccination status of HCWs in the Butembo Antenna in the Eastern Democratic Republic of Congo (DR Congo) and to investigate the factors influencing hepatitis screening and vaccination., Methods: A cross-sectional study using a structured questionnaire was carried out from 1 st to 30 th April 2021 among consenting HCWs in Butembo (≥18 years of age). Data was analysed using SPSS version 23., Results: Of 373 participants, 178 (47.7%) had already been screened for HBV. Screening was more likely for HCWs in a rural or publicly owned facility ( P <0.05). A total of 25 (6.7%) HCWs were fully vaccinated against HBV; the factors associated with full vaccination were: prior screening for HBV (odds ratio: 9.03 (2.51-38.61), P <0.0001), prior knowledge of the value of post-exposure prophylaxis (odds ratio 12.9 (2.89-80.44), P =0.0004), prior knowledge of hepatitis B vaccine benefits (adjusted odds ratio: 4.54 (1.66-13.05), P =0.002) and prior exposure to hepatitis B infection (adjusted odds ratio: 2.61 (1.08-6.39), P =0.039)., Conclusion: Screening and vaccination rates of HCWs for HBV are extremely low, and not high enough to prevent the spread of this serious illness and its complications. There is a dire need to increase vaccination rates among HCWs in Eastern DR Congo. The DRC government should issue vaccination against HBV as a recommendation at the national level., (© 2022 The Authors.)

Background: Predictions have been made that Africa would be the most vulnerable continent to the novel Coronavirus disease 2019 (COVID-19). Interestingly, the spread of the disease in Africa seems to have been delayed and initially slower than in many parts of the world. Here we report on two cases of respiratory distress in our region before the official declaration of the disease in December 2019, cases which in the present times would be suspect of COVID-19., Case Presentation: These two cases (one 55-year-old man and one 25-year-old woman) of acute respiratory distress secondary to atypical pneumonia were seen in Bukavu, in Eastern Democratic Republic of the Congo (DRC), between September and December 2019. One patient had returned from China and the other had close contacts with travellers from China in the 2 weeks prior to the onset of symptoms. In either case, the aetiology could not be accurately determined. However, the two cases presented a clinical picture (progressive dyspnoea, preceded by dry cough and fever) and laboratory changes (procalcitonin within the normal range, slight inflammation, and lymphopenia) compatible with a viral infection. The chest X-ray series of the first patient showed lesions (reticulations, ground glass, and nodules ≤6 mm) similar to those currently found in COVID-19 patients. In addition, unlike the 25-year-old female patient who had no comorbidity, the 55-year-old male patient who had hypertension as comorbidity, developed a more severe acute respiratory distress which progressed to death., Conclusion: These cases bring to the attention the fact that COVID-19-like syndromes may have already been present in the region months before the official beginning of the pandemic. This also brings to question whether a prior presence of the disease or infections with related virus may account for the delayed and less extensive development of the pandemic in the region.

Background: The World Health Organization recommends the integration of vaccination against hepatitis B virus (HBV) into the national immunisation programmes of all highly endemic countries. Protective efficacy, defined as a hepatitis B surface antibody (HBsAb) level ≥10 mIU/mL, is ideally obtained in &gt;90 - 95% of immunised children. The Democratic Republic of the Congo (DRC) implemented this recommendation in 2007 by introducing administration of hepatitis B vaccine in a combined formulation., Objectives: To assess the rate of seroprotection in children who received hepatitis B vaccine in the DRC context., Methods: This descriptive cross-sectional study was conducted during routine postnatal consultations at the General Hospital of Bukavu in South Kivu Province, DRC. A total of 200 infants aged 6 - 12 months and their mothers were consecutively enrolled. All the infants received the three-dose regimen of hepatitis B vaccine 6, 10 and 14 weeks after birth. The mothers were tested for hepatitis B surface antigen and HIV, while HBsAb levels were measured in the infants to determine immune response., Results: Seroprotection was achieved in 84.5% of the infants. No maternal (age, parity, duration of pregnancy, HIV and HBV status) or infant (sex, weight at birth) factors were found to be associated with absence of immunological response., Conclusions: The study demonstrated that the rate of seroprotection in the current vaccination programme against HBV in DRC was lower than desirable but comparable to rates reported in some other African countries. Further studies are needed to assess this finding and to evaluate ways to optimise the seroprotection rate.

Hepatitis B virus (HBV) genotypes show a distinctive geographical distribution worldwide and genotypes A, D, and E are the most frequently found in Africa. There are only limited studies on HBV genotype distribution in Democratic Republic of Congo (DRC), all done in the western part showing a vast majority of genotype E. In our study, HBV strains from South Kivu, an eastern province of the DRC, were analyzed. Sequencing of 41 serum samples from HBV infected patients revealed strains of genotype A in 40/41 (97.6%) and genotype E in 1/41 (2.4%). The phylogenetic analysis showed that nearly all genotypes A (38/40) were closely related to A1 subgenotype strains found in Rwanda, Haiti, and Martinique while only two strains attached to the A2 subgenotype cluster were isolated. The remaining genotype E case was linked to the western African E crescent. Only the I169T nucleotide substitution was observed in two genotype A samples. In conclusion, the genotype A seems to be the most predominant genotype in eastern DRC with the majority belonging to the Afro-Asian subgenotype (A1). This contrasts with the western part of DRC where genotype E is predominant. These results support the hypothesis of an East-West genotypic demarcation., (© 2017 Wiley Periodicals, Inc.)

Health-care workers (HCWs) are at risk of infections associated with accidental exposure to blood, including viral hepatitis B (HBV) and C (HCV). A survey using a questionnaire was conducted on 250 HCW in Bukavu, an eastern town of the Democratic Republic of Congo, to analyze their attitude and knowledge about these two viruses. A response rate of 86.8% (217/250) was obtained. The mean age of the respondents was 39.6 ± 9.8 years, in majority from paramedical staff (66.4%) and with more than 5 years of professional experience (60.8%). The mean proportion of adequate answers on HBV and HCV was 33.2% (±11%) and 30.6% (±7%), respectively. Ninety-three HCW (42.8%) reported recent experience of blood exposure accident, more frequently among the paramedical staff (50%) than physicians (28.8%; P = 0.002). This was mainly related to inadequate protection resources (76.9%). Among all participants, only 24.4% had a history of at least one injection of HBV vaccine; this was more frequently found among physicians than among paramedical staff (49.3% versus 11.8%; P < 0.001). Moreover, only 3.8% of vaccinated HCW received the complete vaccination schedule of three vaccine doses. The efficiency of this vaccine is not well recognized by HCW, and the majority of them seemed to be more worried about the risk of infection by human immunodeficiency virus than by viral hepatitis. Our study reveals that the level of knowledge about HBV and HCV is rather low among HCW in Bukavu., (© The American Society of Tropical Medicine and Hygiene.)
