Background: The success of antiretroviral therapy requires better virological monitoring. We described the virological profile of patients on combined antiretroviral therapy (cART) for HIV/AIDS in Bangui, Central African Republic (CAR). Methods: In this prospective cohort study of patients who had been on combined antiretroviral therapy treatment (cART) for at least 12 months in Bangui, only one HIV plasma viral load per patient was realized at the Institut Pasteur of Bangui, between April 4th and November 28th, 2017. Sociodemographic and biological data were collected. Blood samples were taken for viral load. The biocentric generic human immunodeficiency virus (HIV) load test was used to quantify a ribonucleic acid (RNA) HIV-1. Data were analyzed with Stata software version 14. Chi-squared test was used to analyse viral load according to sex and age. The level of significance was set at P ≤ 0.05. Results: A total of 3569 patients were recruited, with a mean age of 40 years (median, 42 years;range, 1 - 84), patients aged 40 - 49 predominating (34.2%). The sex ratio was 0.4. No virus was detectable in plasma from 49.2% of patients, while 42.4% had virological failure (viral load, ≥1000 copies/mL) according to WHO criteria. The risk for virological failure decreased with age (P = 0.001) and was higher among females than males (P = 0.001). Conclusions: The rate of virological failure among patients on cART is very high in the CAR, despite the availability of and access to monitoring of HIV plasma viral load in Bangui. Therefore, adherence to treatment should be evaluated and reinforced in Bangui, CAR. 展开更多

Background: The biological profile of HIV-positive patients is essential for diagnosing treatment failure and the prognosis of infection. We determined the virological and immunological profiles and biological anomalies of HIV-positive people on antiretroviral therapy (ART) in Bangui, Central Afri-can Republic. Methods: We conducted an analytical, descriptive study be-tween 4 April and 30 September 2017 of all patients who had received ART for more than 12 months and who attended the Medical Analysis Laboratory of the Institut Pasteur in Bangui for a complete biological work-up, including viral load. A blood sample was taken for quantification of RNA HIV-1, CD4 lymphocytes and blood count in two tubes containing ethylenediamine te-traacetic acid, and another sample was taken in a dry tube for measurement of creatinine and transaminases. Results: The total population comprised 1748 patients, with a mean age of 38.7 years (±14.3;median, 41 years;range, 2 - 79 years);33.3% of patients were between 40 and 49 years old. Females predo-minated (71.3%), for a sex ratio of 0.4. Immunological failure was observed in 20.2% of patients (CD4 Conclusion: The abnormalities observed in this study concerned the haematopoietic system, the liver and the kidneys. As other or-gans and systems may be affected, periodic multidisciplinary biological and clinical follow-up is necessary for people living with HIV in order to improve their management. 展开更多

Introduction: The Central African Republic is one of the 30 high Tuberculosis burden countries in the world, with an incidence of 540 cases per 100,000 population and a mortality of 91 deaths per 100,000 population. Since 2020, following WHO recommendations, the National Reference Laboratory for Tuberculosis has been using the Xpert<sup>&#174</sup> MTB/RIF assay as a first-line diagnostic test for the early detection of Drug Resistance Tuberculosis. The goal of this study was to evaluate the contribution of the Xpert<sup>&#174</sup> MTB/RIF assay to the surveillance of rifampicin resistance in new and previously treated tuberculosis cases. Materials and Methods: The data relative to the Xpert<sup>&#174</sup> MTB/RIF assay carried out on various categories of tuberculosis patients registered at the National Reference Laboratory for Tuberculosis in 2020 were analyzed retrospectively. The categories of tuberculosis patients were new cases, failed treatment cases, relapse cases, lost-to-follow-up cases and multidrug-resistant tuberculosis contact cases. Results: A total of 1404 tuberculosis patients were registered at the NRL-TB in 2020;the mean age was 39.2 years (2 - 90 years) and the male-to-female sex ratio was 1.16:1. Overall, 32.7% (454/1404) proved infected with tuberculosis, of which 22.5% (102/454) cases showed resistance to rifampicin. The primary resistance rate was 9.1% (27/298) and the secondary resistance rate was 46.6% (75/161). Treatment failures and relapsed cases were significantly associated with rifampicin resistance (p 0.005). Conclusion: Large-scale use of Xpert<sup>&#174</sup> MTB/RIF, especially in the provinces of the Central African Republic, will help the Ministry of Health to better control Drug Resistance Tuberculosis in the country. 展开更多

<strong>Introduction</strong> In Central-African Republic, according to UNAIDS in 2019, out of approximately 100,000 people living with HIV, 70% (72,000) knew their HIV status and 47,000 (46%) were on ARV ... <strong>Introduction</strong> In Central-African Republic, according to UNAIDS in 2019, out of approximately 100,000 people living with HIV, 70% (72,000) knew their HIV status and 47,000 (46%) were on ARV therapy;however, there is a paucity of data on viral load suppression in people on ARV therapy. The objective of this study was to assess the third 90 of the UNAIDS strategy for the years 2019 and 2020 in the CAR. <strong>Methods</strong> We analyzed the available viral load data extracted from the data base of the medical analysis laboratory (SYSLAM) of the Institut Pasteur of Bangui for the years 2019 and 2020. The viral loads were determined based on plasma collected in an EDTA tube with Cepheid’s GeneXpert<sup><span style="white-space:nowrap;">&#174;</span></sup> 16-module controllers. Viral load data were extracted from SYSLAM, converted to Excel format, and analyzed with STATA version 14 software. The significance threshold for the statistical tests was set at 5%. <strong>Results</strong> This study included 22,895 patients, of who 72% were female. The average age was 40.82 years, and the majority of the patients (80%) came from the city of Bangui. Regarding the virological parameters associated with this study, 66% of the patients had significant viral load suppression according to the WHO recommendations and 34% were in virological failure. Patients over 50 years of age (71.85%) and age group 40 - 49 years (69.25%) recorded significant levels of viral load suppression. On the other hand, 63.45% of patients under 18 years of age had virological failure. All of these results were statistically significant (p < 0.005). <strong>Conclusion</strong> There should be a concerted effort, to make viral load accessible and available to all patients receiving ARV treatment in the CAR and the management of HIV/AIDS infection of children and adolescents should be given special attention. 展开更多

Introduction: The clandestine abortions remain a major health problem in developing countries including the Central African Republic. At the main maternity hospital of Bangui in the Central African Republic, a study conducted in 2000 indicates that clandestine abortions (CAs) accounted for 43.4% of all abortions recorded in the service. The purpose of our study was to evaluate the evolution of CAs about the health care management efforts made over the last 4 years. Patients and Methods: We conducted a prospective descriptive and analytical study over a period of 4 years (from January 2016 to December 2019). This study focused on the complications of clandestine abortions that occurred during the course of our study at the HCB reference maternity hospital. Results: We identified 267 clandestine abortions for 783 spontaneous abortions. The frequency of CAs was 34.1%. The highest number of CAs was observed in patients aged between 20 and 24 years with an average age of 23.7 years. The average parity was 2.6. It appeared in our study that students were the most represented (40.8%). Rescuers were the most incriminated (29.2%) in clandestine abortion (CA). Infectious complications predominated in (79.1%) of cases. Antibiotic therapy was almost systematic (96.6%). Laparotomy was performed in (38.9%) cases. The proportion of deceased women who had a pregnancy of more than 12 weeks was higher with a statistically significant difference (p 0.001). Conclusion: Abortion affects all women regardless of age, parity, marital status and socio-economic status. 展开更多
