In Human immunodeficiency virus infected (HIV+) patients, deregulation of regulatory T (Treg) cells can be deleterious for the development of an efficient anti-HIV specific immune response with an inappropriate immune activation despite anti-retroviral therapy (ART). In addition, infection and ART have the potential to cause hematological and biochemical abnormalities that can lead to the discontinuation of ART. The aim of this study was to assess hematological, biochemical and immunological abnormalities in HIV+ patients’ naïve to ART and 6 months after ART initiation. In a cross-sectional study, 11 HIV+ patients and 09 healthy individuals (control group) were voluntarily recruited. At inclusion, blood samples were taken before administration of ART. All hematological, biochemical, immunological parameters and viral load were measured and assessed at inclusion (M0) and three and/or six months later (M3, M6). Higher level of white blood cells and CD4+ T lymphocytes (p = 0.032, 0.038 respectively) were observed in HIV+ patients. ART also had significantly effect on the level of red blood cells (p = 0.04) and Hb (p = 0.015). The inflammatory markers, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) that were significantly increased by HIV infection, tended to decrease for ESR and revert to levels similar to those of control for CRP. Analysis of CD4+CD25+ cells and CD4+Foxp3+CD25+ showed significantly elevated levels of activated form of all CD4+ cells and Treg cells. Interestingly, six months after initiation of ART, the average percentage of CD4+CD25+ was not significantly different from control group (p = 0.382). Our study provides information about the evolution of the activated form of all CD4 cells and Treg cells and points out the necessity to monitor hematological and biochemical parameters in order to detect and prevent toxicity, improve the quality of life and reduce the risk of mortality.

Knowledge of the clinical and biological profile of patients infected with HIV and hepatitis B and/or C is essential in order to identify and implement effective management strategies. Methods: This was a retrospective descriptive study from January 01, 2016 to June 01, 2021. Adult patients aged at least 18 years infected with HIV type 1 and/or 2, na?ve to ARV treatment. Univariate analyses were assessed using Pearson’s Chi2 test. The Student Newman test was used for comparison between groups using R software version 4.0.2. Objective: To draw up the epidemiological, clinical, paraclinical and evolutionary profiles of HIV-treated-patients in relation to HIV/HBV and HIV/HCV co-infections in order to allow the identification and the implementation of effective management strategies. Results: Of the 379 patients included 280 (73.88%) were women. At treatment initiation, the mean age was 40.14 ± 11.84 years. The majority of patients consulted at WHO stage III (51.45%). Clinical suspicion was the most frequent screening circumstance (51.71%). The pathologies frequently reported at the first consultation were diarrhea (28%) and shingles (16%). Body mass index was normal in 50.5% of patients. HIV1 infection was the majority (91.03%). A total of 270 had a CD4 count at treatment initiation. The mean CD4 cell count was 304.17 ± 242.06 cells/μL, and 116 (42.59%) of them had a CD4 ≤ 200 cells/μL. Viral load at treatment initiation was documented in 62 patients (16.35%) and 70.97% of them had a detectable viral load (greater than 1000 copies/mL). The clinical and biological evolution was relatively good in patients after therapeutic initiation. HIV-HBV co-infection was 24.11% and HIV-HCV co-infection was 2.26%. The mortality rate was 3.69%. Conclusion: These results reflect a significant delay in HIV infection diagnosis. Furthermore, hepatitis B and/or C is co-infections that increasingly affect people living with HIV. It also appears that COVID 19 disease has had a strong impact

The risk to develop an infection after surgery depends on several factors. Those factors may be interdependent or not, depending on the nature of the surgery and the general condition of the patient. The aim of the present study was to identify the factors involved in the occurrence of the Surgical Site Infections (SSI) in the National referral general hospital of N’djamena (Chad). We first realized an interview in the emergency services and in the general surgery of the hospital. The information collected allowed us to draw up survey sheets. An investigation was then conducted on 152 patients who had surgery and were hospitalized during the study period. The frequency of the SSI was 33.6% (51/152). The main risk factors that we identified were the duration of hospitalization, the category of the hospitalization room, the urgent aspect of the surgical intervention, the patient’s nutritional status and the associated diseases with diabetes, which was present in 52.38% (11/21) of cases of associated pathologies. Analysis of the antibiotic prophylaxis administered to patients showed that ciprofloxacin was more effective in SSI prevention. Indeed, this antibiotic showed the fewest cases of infection with only 1.9% of patients having developed SSI. Our results show a very high frequency of SSI at the National referral general hospital of N’djamena. Poor hospital practices and factors associated to patients seem to be the most factors implicated in the SSI.

Objective: The aim of this study was to characterize the polymorphisms of the DC-SIGN (-336 A/G, rs4804803) gene and their association with the immunopathogenicity of dengue fever in Burkina Faso. Methods: A total of three hundred forty-one subjects, patients of all ages have been included in the study: 208 persons presenting clinical signs of dengue fever which were confirmed by diagnostic and 133 Healthy Controls. Genotyping for the CD209 variant (-336 A/G, rs4804803) was carried out using TaqMan SNP Genotyping Assays. Haplotype frequencies were inferred and compared between the study groups. Results: The percentage of men was 61.88% (211/341) and 38.12% (130/341) for women. The highest frequency of dengue fever (77.42%) was noted in patients with age between 20 to 40 years. Around 1.52% of the study population was positive for HIV, 40.55% were carriers of HBV and 3.83% of HCV. Genotype distribution of the CD209 variant (-336 A/G, rs4804803) was in Hardy-Weinberg equilibrium in both patients and controls. The frequency of allele A was higher than allele G;however, statistical analyses showed that there is no significant difference in genotypes GG, AG and AA in patients and controls. Conclusion: This related no significant association with dengue for the variant of ?336 A/G in the DC-SIGN gene in an Ouagadougou population. However, our results offered the SNP frequencies in a West African population, which might be useful for the study of ethnic groups.

Human papillomavirus (HPV) is classified into high-risk HPV (HR-HPV) and HPV (LR-HPV) according to their oncogenic potential. These viruses can be found in the cervix, vagina, vulva, anus and in the ENT sphere. HPV ENT infections can lead to benign or malignant tumors in which we could find both LR-HPV and HR-HPV genotypes. The objective of this study was to investigate the genotypes of HR-HPV and LR-HPV in archived tissue samples derived from both benign and malignant tumors of the ear, nose, and throat (ENT) in Ouagadougou, Burkina Faso. One hundred and twenty formalin-fixed, paraffin-embedded archived tissues of the ENT sphere from 26 benign tumors and 94 malignant tumors were included. The tissues were first deparaffinized with xylem. The extracted DNA was used to test for high-risk and low-risk HPV by Real-Time Multiplex PCR. HPV DNA was found in 57.7% (15/26) of benign tumors and 43.61% (41/94) of malignant tumors. The prevalence of HPV infection was 46.67% (56/120) in all tumors combined. The most common HPV genotypes found were HPV 11 (34.28%), HPV 6 (30%), HPV56 (14.28%) and HPV 33 (8.57%). There were 21.43% (12/56) cases of genotypes co-infections with 10 cases of double infection and 2 cases of triple infection. Both low-risk and high-risk HPV are found in ENT tumors with relatively high HPV prevalence.

Rotaviruses, noroviruses, and astroviruses are responsible for gastroenteritis in children under 5 years old. The objective of our study was to estimate the evolution of prevalence of rotavirus, norovirus and astrovirus infections in children aged 0 to 5 years with gastroenteritis, after the introduction of rotavirus vaccines in Burkina Faso. This cross-sectional study was conducted between January and December 2023, collecting 100 stool samples from children with gastroenteritis at Saint Camille Hospital in Ouagadougou and the Charles De Gaulle University Paediatric Hospital. Noroviruses and astroviruses were detected using multiplex real-time PCR with a Sacace biotechnology detection kit. Data analysis was performed with Stata statistical software, version 16.0. The prevalence of norovirus infections was 14% and astrovirus infections were 9%. Rotavirus infections were found at prevalence of 15%. The age group most affected by norovirus and astrovirus infections was 0 - 12 months, with respective prevalence rates of 73.34% and 55.56%. The most frequently observed clinical signs in children infected with astrovirus were fever (77.78%), diarrhea (55.56%), and vomiting (44.44%). The introduction of rotavirus vaccines has reduced rotavirus-related infections. However, this has not significantly impacted the prevalence of norovirus and astrovirus infections in Burkina Faso.

Although persistence of high-risk human papillomavirus infection is the main risk factor, Glutathione S-Transferase highly polymorphic enzyme involved in the metabolism of xenobiotics, is a good candidate gene. The objective of this study was to compare the polymorphisms of Glutathione S-Transferase M1-null in women with cancerous lesions and without lesions. This study consisted of 322 uterine cervix samples of women from Mali and Burkina Faso with Cervical Intra-epithelial Neoplasia 2 and 3, adenocarcinoma and squamous cell carcinoma and 100 women with no lesions. Human Papillomavirus genotyping was performed by Real-time multiplex Polymerase Chain Reaction. Glutathione S-Transferase gene polymorphisms were determined using conventional Polymerase Chain Reaction followed by migration on agarose gel. A statistically significant association with high relative risks of 10.77 for the development of High grade Superficial or Squamous Intra-epithelial Lesion (95% CI = 5.59 - 20.72;p ype of Glutathione S-Transferase M1 in the study population. In Burkina Faso and Mali, Glutathione S-Transferase M1-null presented relative risks of 9 and 11.05 for high-grade lesions, 15 and 11.40 for cancer. Similarly, significant results had been observed in women with human papillomavirus positive and human papillomavirus negative. The results of the present study support the idea that the deletion of Glutathione S-Transferase M1 plays a crucial role in the progression of high-grade lesions and cervical cancer.
