The highly active antiretroviral treatment (HAART) has allowed people living with HIV to live longer with a better quality of life. However, toxicity and the emergence of drug resistance arise from HAART use. Therefore, new antiretroviral therapy is needed since no cure or vaccine is available against HIV. Virus-host interaction has been proven to be important in the last decade. Host factors such as the C-C chemokine receptor type 5 (CCR5), a receptor used by HIV to penetrate host cells, have led to the discovery of the Maraviroc, which is an antiretroviral medication used in the United States. In contrast, other factors like C-X-C Motif Chemokine Receptor 4 (CXCR4) and the Apolipoprotein B mRNA editing enzyme catalytic polypeptide-like 3G (APOBEC3G), a potent host defense factor against HIV, is under investigation. APOBEC3G antiviral activity remains a possible therapeutic target against HIV. This systematic review aimed to synthesize the available evidence on the role of APOBEC3G polymorphisms and their expression on HIV infection disease progression in Africa. We used Web of Science, PubMed, Embase, and Google Scholar and searched for relevant publications in French or English reporting on APOBEC3G polymorphisms association with HIV infection in African populations from January 2009 to May 2023. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyzes) was used to process for reporting systematic review. Fifteen studies were included, of which seven were on APOBEC3G polymorphisms and eight were on APOBEC3G expression. Among the APOBEC3G polymorphisms, the most studied was H186R or rs8177832. The average of the minor allele frequency of H186R of APOBEC3G available for the studies included in this study was 0.29 with a 95% CI (0.172;0.401) and varied from 0.108 reported in Uganda to 0.47 recorded from Burkina Faso. The polymorphism H186R was not associated with HIV status in Southern Africa. However, the referent allele of H186R was protectiv

Introduction: Neonatal pathology remains a real public health problem in developing countries. In Burkina Faso, this mortality has declined over the last ten years but remains below compared to the Sustainable Development Goals, which is 12 per 1000 living births at most by 2030. This study aims to identify specific causes of neonatal morbidity and mortality and will contribute to the implementation of preventive and curative measures aimed at reducing neonatal mortality at HOSCO. Method: This was a retrospective study using the records and database of newborns hospitalized from January 1srt, 2017 to December 31srt, 2020. Using logistic regression, the factors associated with mortality were determined. Results: During the study period, 3020 newborns were hospitalized. Most newborns (83.71%) were referred by a peripheral health facility. The average age at admission was 0.3 days ± 0.9 and the sex ratio was 1.2. Prematurity was the leading cause of hospitalization (61.13%) followed by neonatal infection (38.34%) and neonatal suffering (23.88%). The mortality rate was 40.6% with 82.71% cases of death in the early neonatal period. The main causes of death were low birth weight (47.39%), respiratory distress (18.76%), neonatal suffering (17.37%) and neonatal infection (13.87%). Home delivery, gestational age 36 weeks, number of PNC 4, concept of resuscitation, Apgar at the 5th minute 7, birth weight 2000 g and >4000 g, respiratory distress, hypothermia, neurological disorders were factors associated with deaths. Conclusion: Neonatal mortality is influenced by both maternal and fetal factors and many of them are preventable.

Background: The World Health Organization (WHO) has set a goal to eradicate or at least significantly reduce the prevalence the human immunodeficiency virus (HIV), hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) by 2030. The main objective was to provide an evolving overview of the prevalence of HIV, HBV and HCV infection between 2003 and 2022 in Burkina Faso. Methods: It was a retrospective cross-sectional study based on data from 2003 to 2022. The data were collected using information available in the databases of the HOSCO and CERBA laboratories and included all individuals who underwent HIV and/or HBV and/or HCV testing. Data analysis was performed using SPSS version 20.0, EpiInfo 7, and R version 4.1.0. Results were considered statistically significant if p Results: The study recorded 7432 samples and the mean age of the subjects was 27.98 ± 8.50 years. During this period, the respective prevalence of HIV, HBV, and HCV were 4.66% (346/7432), 8.77% (582/6636) and 5.54% (322/5816). However, from 2003 to 2022, there was a significant decrease (P y=−1.75x+12.59;y=−0.24x+10.01and y=−0.11x+6.02, with “y” corresponding to prevalence and “x” to the years. Conclusion: Burkina Faso needs to rigorously apply prevention and control strategies recommended by the WHO by 2030.

Resistant bacteria can be transmitted to humans through feces or contaminated meat from local chickens. Bacterial strains were isolated from the intestinal contents of 400 local chicken samples from various sales sites. These strains were then characterized using bacteriological and biochemical methods to identify resistant strains. In a study conducted in Ouagadougou, we systematically collected chicken fecal samples from 20 locations across the city, followed by isolation and identification of Salmonella spp. using specific enrichment and culture methods, as well as Escherichia coli. Bacterial strains were characterized using antibiotic resistance profiles were determined through agar diffusion tests, revealing sensitivity or resistance to a range of antibiotics based on established scientific criteria. The results showed that out of the 400 samples collected, 81.25% and 63.5% were contaminated by Escherichia coli and Salmonella spp., respectively. Among these, 86.15% of identified Escherichia coli and 50.78% of Salmonella spp. displayed resistance to at least one tested antibiotic. Among 280 Escherichia coli isolates identified resistant to at least one antibiotic, 31.07% were resistant to cefotaxime (CTX), 20.35% to ceftazidime (CAZ), 21.07% to ceftriaxone (CTR), 75% to amoxicillin clavulanic acid (AMC), 23.57% aztreoname (ATM) and 27.14% were resistant to imipenem (IMP). In the case of the 129 Salmonella spp. isolates resistant to at least one tested antibiotic, 34.88% were resistant to CTX;41.08% to CAZ;35.65% to CTR, 92% to AMC, 39.53% to ATM and finally 47.28% were resistant to IMP. Our study revealed high prevalence of resistance in bacterial strains isolated from local chickens sold outdoors in Ouagadougou. These findings raise significant public health concerns, due to the possible transmission of these resistant strains to humans through the consumption of contaminated meat, thus complicating the treatment of bacterial infections.

Introduction: Human papillomavirus (HPV) infection is the most widespread sexually transmitted infection in the world. Today, there is growing evidence that HPV can be transmitted early in life, and one potential route is mother-to-child transmission. Data on this route of HPV transmission are scarce in Africa and particularly in Burkina Faso, where no data on the subject are yet available. The aim of our study was to estimate the rate of mother-to-child transmission of HPV infection and to identify circulating genotypes. Methodology: Cervico-uterine samples were collected from 100 full-term pregnant women and, buccal samples were obtained from their newborns at Hopital Saint Camille de Ouagadougou (HOSCO) by the specialist physician. HPV DNA amplification and genotyping were performed by PCR followed by hybridization using the HPV Direct Flow Chips kit, detecting 36 genotypes including 18 high-risk and 18 low-risk. Results: The prevalence of HPV in newborns was 8% (8/100). Six (6) HPV-positive neonates had HPV-positive mothers, while 2 HPV-positive neonates had HPV-negative mothers. The vertical transmission rate was 26.09% (6/23). Mother-newborn genotypes were concordant. However, the genotype profile of the newborns was more restricted than that of the mothers. Conclusion: HPV DNA was found in 8% of newborns in our study. The genotype profile of the mother-newborn pair was concordant. Asymptomatic HPV infection in a pregnant woman could constitute a risk factor for vertical transmission.

The severity of hepatic pathology and the response to treatment depend on the hepatitis virus genotype in the infected host. The objective of this review was to determine the distribution of hepatitis virus genotypes in West African countries. A systematic review of the literature in PubMed, Google Scholar and Science Direct was performed to identify 52 relevant articles reporting hepatitis A, B, C, D, E and G viruses *** B virus(HBV) genotype E with a prevalence of 90.6%(95%CI: 0.891-0.920) found in this review, is characterized by low genetic diversity. Hepatitis C virus(HCV) genotypes 1 and 2 represented 96.4% of HCV infections in West African countries, while hepatitis delta virus, hepatitis A virus, hepatitis G virus genotypes 1 and HEV genotype 3 were reported in some studies in Ghana and Nigeria. HBV genotype E is characterized by high prevalence, low genetic diversity and wide geographical distribution. Further studies on the clinical implications of HBV genotype E and HCV genotypes 1 and 2 are needed for the development of an effective treatment against this viral hepatitis in West African countries. Surveillance of the distribution of different genotypes is also needed to reduce recombination rates and prevent the emergence of more virulent viral strains.

Journal of Biosciences and Medicines 2023年第1期11卷 57-69页

Burkina Faso is a malaria-endemic country, with a high incidence of G6PD deficiency (G6PDd), which recorded its first case of COVID-19 in March 2020. G6PDd leads to a decrease in the efficiency of erythrocytes to combat oxidative stress, while SARS-CoV-2 infection induces massive production of Reactive Oxygen Species (ROS) in patients. In the present review, we discuss a possible link between G6PDd and SARS-CoV-2 infection. The mean prevalence of G6PDd in Burkina Faso is estimated at 16.6% among males and 6.5% among females. A total of 21,128 cases of COVID-19 have been recorded in Burkina Faso with 387 deaths reported (with a mortality rate of 1.15% among diagnosed cases) as of August 30, 2022. To our knowledge, no association study between G6PDd and SARS-CoV-2 infection has been conducted to date in Burkina Faso. However, several case reports around the world have described elevated risks of hemolysis and thrombosis, and other complications among G6PD-deficient patients infected with SARS-CoV-2. The use of Hydroxychloroquine (HCQ) has also been deemed unsafe by some authors for the treatment of COVID-19 among patients with G6PDd. Although HCQ has been shown to be well tolerated in COVID-19 patients in Burkina Faso, the drug could induce hemolytic crises in people with G6PD deficiency. G6PD is important in regulating ROS and maintaining erythrocyte homeostasis. In view of its high prevalence in Burkina Faso, determination of the G6PD status is required in COVID-19 patients for adequate management such as identifying a subset of COVID-19 patients for whom close monitoring and supportive care may be essential and to restrict treatment with HCQ.
