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.

Introduction: Genetic polymorphisms of some Glutathione S-Transferase (GST) which encode the enzyme responsible for the biotransformation of drugs and xenobiotics, have been associated with the risk of several pathologies that can progress to cancer such as Hepatitis B. This study aims to characterize the impact of the rs1695 polymorphism of GSTP1 gene among people with chronic Hepatitis B infection in Burkina Faso. Methods: rs1695 polymorphisms of GSTP1 gene genotyping was performed for 50 people infected with chronic Hepatitis B virus and 124 healthy people with the PCR-RFLP method. Conventional PCR was used for DNA amplification and Alw26I enzyme was used for enzymatic digestion. Results: The results show that the frequencies of AA, AG and GG genotypes are respectively 31.00%, 36.80% and 32.20% in general the study population with a mutation rate of 50.57%. However, the incidence of the AA, AG and GG genotypes are respectively 30.64%, 38.71% and 30.64% among people with chronic Hepatitis B virus infection and 32.00%, 32.00% and 36.00% among healthy people. In cases, the frequencies of the A and G alleles are 48.00% and 52.00% respectively, and in controls 50.00% each. No statistical difference was found by comparing genotypic and allelic frequencies between cases and controls (p > 0.05). Conclusion: Our study allowed us to determine the rate of GSTP1 rs1695 genotypes in the study population, cases and controls. From our analyses, GSTP1 rs1695 is not associated to chronic Hepatitis B virus infection in Ouagadougou.

Urinary tract infections (UTIs) caused by uropathogens are a significant public health problem, and their treatment primarily relies on antibiotic therapy. However, the increasing global development of antibiotic resistance necessitates updating diagnostic techniques to ensure higher sensitivity and specificity, especially with advancements in science and medicine. This study aimed to evaluate the prevalence of UTIs and antibiotic resistance profiles through urine culture, as well as to identify Klebsiella pneumoniae, Klebsiella oxytoca, and Acinetobacter spp. in urine samples using a molecular approach with multiplex real-time PCR. From May 3 to July 25, 2023, at the Pietro Annigoni Biomolecular Research Center (CERBA) and Saint Camille Hospital of Ouagadougou (HOSCO), 209 urine samples collected from patients with suspected UTIs were analyzed using both urine culture and multiplex real-time PCR. Among the 209 patients, 52.15% were male and 47.85% female, with an average age of 46.87 ± 21.33 years. Urine cultures revealed an overall UTI prevalence of 23.44%, with a prevalence of 8.13% in men versus 15.31% in women (P = 0.023). The bacterial prevalence rates were as follows: Escherichia coli (12.92%), Klebsiella spp. (7.18%), Enterobacter cloacae (1.44%), Staphylococcus aureus (0.96%), and other bacteria. Klebsiella spp. demonstrated 100% resistance to Amoxicillin and Amoxicillin/Clavulanic Acid, while Escherichia coli showed 96.2% and 65.4% resistance to Amoxicillin and Amoxicillin/Clavulanic Acid, respectively. PCR analysis of the target bacteria revealed mono-infection prevalence rates of Klebsiella pneumoniae (10.39%), Klebsiella oxytoca (7.79%), and Acinetobacter spp. (7.79%), along with a co-infection prevalence rate of Klebsiella pneumoniae/Acinetobacter spp. (1.30%). This study demonstrated that PCR, with its high sensitivity and specificity, could effectively distinguish Klebsiella pneumoniae from Klebsiella oxytoca and detect Acinetobacter spp. in less tha

Introduction: Cervical cancer is a public health concern and is mainly caused by Human papillomaviruses (HPV). In many parts of the world, studies are being carried out to understand the different genotypes to better tackle this issue. We conducted a study to determine the prevalence of HPV genotypes in women with chronic hepatitis B or C infection, co-infected or not with HIV, treated at the Hôpital Saint Camille in Ouagadougou (Burkina Faso). Methods: This study was conducted from April to July 2023, including 100 women in gastroenterology at Hôpital Saint Camille. A questionnaire on their socio-demographic and life style was administrated;and endocervical samples were collected using sterile swabs and then sent to Centre of Biomolecular Research Pietro Annigoni (CERBA). HPV molecular detection and genotyping were performed by PCR and hybridization using the HPV Direct Flow Chips kit. Data were analysis using chi square test or Fischer’s exact test with a significance threshold for p Results: The prevalence of HPV infection was 28% (28/100) on the sample of women tested. The most frequent genotypes were HPV 52 (8.33%), followed by HPV 18 and 68 (6.25% each) for high-risk HPVs, and HPV 6, 44/55 and 62/81 (8.33% each) for low-risk HPVs. Conclusion: This study, the first of its kind in Burkina Faso on this group of the population, reveals that the most frequent genotypes found in this study are not included in the vaccine available in Burkina Faso (Gardasil®4).

Background: Neoadjuvant chemotherapy (NAC) is one of the treatment options for breast cancer. Its aim is to significantly reduce the size of the tumour in preparation for surgery. The aim of this work is to analyze the conditions of clinical and radiological evaluation of NAC at the Yalgado Ouédraogo University Hospital (CHUYO). Patients and Methods: This was a descriptive cross-sectional study based on the medical records of patients followed up in the cancer department of the CHUYO from 1 January 2013 to 31 December 2021. All patients followed for histologically proven, non-metastatic breast cancer and having received at least one course of NAC were included in this study. The variables were related to the socio-demographic characteristics of the patients, the indications, the protocols of NAC and the sequences of evaluation of the tumour response (clinical, radiological and anatomopathological). Results: We collected 105 cases. The average age of the patients concerned was 44 years. The most frequent histological type was non-specific invasive carcinoma in 97.1% of cases. Immunohistochemically, triple-negative patients accounted for 51.4%. At the initial stage, all patients underwent clinical exploration. Clinical measurement of the tumour was performed in 70.5% of cases. The radiological size of the tumour was determined by ultrasound in 59.1% of cases. One patient had a breast MRI. Thirty-one patients were lost to follow-up after the initial evaluation. At mid-term and at the end of treatment, clinical tumour size was performed in 38.6% and 45.6% of cases respectively. There was no breast imaging performed at mid- and end-of-treatment. CT scans were performed in all cases at baseline, mid-term and end of treatment for extension assessment but did not mention the breast tumour. The tumour response rate was not recorded. Conclusion: Clinical assessment of tumour response is almost always empirical and not quantified. Medical imaging examinations are prescribed sp

Background: The assessment of liver fibrosis is an essential part of the fol-low-up of patients with chronic HBV. Ultrasound and fibroscan are two com-monly used non-invasive examinations and the purpose of this study is to as-sess the correlation between the results of these two examinations in the as-sessment of liver fibrosis. Methodology: This was a descriptive and analytical cross-sectional study with retrospective collection over a period of 30 months from January 01, 2018 to June 30, 2020 on the correlation between the ultra-sound aspects and the results of the fibroscan of patients with chronic carriers of Hepatitis B virus at the Teaching Hospital of Bogodogo and at the faith-based health center CANDAF. Results: A total of 85 patients with fibrosis were collected. The 30 - 40 age group was the most represented (41.18%), with a male predominance of 52.94%. The patients with a married life were the most represented (77.64%), the social stratum the most represented were the middle managers (32.94%). University level was predominant among educa-tion levels (45.64%). The personal history was traditional circumcision (34.12%), excision (21.18%), manicure (16.47%). The circumstances of the findings were blood donation (34.12%), screening (21.18%), fortuitous findings (16.47%). The association between echostructure and fibrosis on the fibroscan scan was significant (homogeneous hyperechoic echostructure p = 0.0028 and granular echostructure p = 0.0001). Fibrosis on scans had a significant associa-tion with liver contour (Regular contours p = 0.0009 and p = 0.0002). Fibrosis on CT scan had a significant association for the diagnosis of fibrosis on ultra-sound (p = 0.0002 for hepatic steatosis and cirrhosis and p = 0.0013 for hepat-ic dysmorphia), on the other hand, no significant association for hepatomegaly (p = 0.8883). Conclusion: Detecting the presence of fibrosis and monitoring its progression improves the management of patients with chronic liver disease. Ultr

Introduction: Cervical cancer, caused by persistent high-risk human papillomavirus (HPV) infection, remains a global public health problem. The cellular transformation and maintenance of the malignant phenotype of these HPVs are attributed to the viral oncoproteins E6 and E7. Objective: This study aims to detect the presence of human papillomavirus DNA and E6/E7 oncoprotein mRNA of HPV genotypes 16, 18, 31 and 33 in cases of cervical cancer and precancerous lesions, histologically confirmed in Burkina Faso. Methods: This descriptive cross-sectional study focused on cases of cervical cancer and high-grade intraepithelial neoplasia (CIN) and was conducted from June to December 2022. One hundred (100) samples of fixed and paraffin-embedded tissues were collected from the pathological anatomy and cytology laboratories of hospitals in the capital of Burkina Faso. High-risk human papillomavirus (HR-HPV) DNA was detected using multiplex real-time PCR, while the presence of E6 and E7 mRNA in cervical cancer and high-grade CIN samples was determined using real-time Reverse Transcriptase-PCR (RT-PCR) with TaqMan probes. Results: The mean age of women diagnosed with cervical cancer and high-grade CIN was 50.81 ± 13.65 years, ranging from 22 to 82 years. Cervical cancer and high-grade CIN were positive for at least one high-risk human papillomavirus (HR-HPV) in 80% of cases. The most prevalent genotypes observed were HPV16, 18, 31, and 33, collectively accounting for 70.08% of cases. Of the 89 samples that tested positive for HR-HPV genotypes 16, 18, 31, and 33, 88 (98.88%;95% CI: [94.58 - 99.94]) were also positive for the presence of mRNA encoding the E6 and E7 oncoproteins of HPV16, 18, 31, and 33. Conclusion: In the presence of HPV DNA, testing for E6 and E7 oncoprotein mRNA could serve as a promising biomarker and valuable tool for improved assessment of the progression to cervical cancer.

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.

Breast cancers classified T4 according to the TNM code are frequent in Burkina Faso. A better knowledge of these cancers would help to better organize the fight against breast cancer in general. We conducted this study to present the clinical and prognostic aspects of T4 breast cancer in Ouagadougou. It was a descriptive retrospective study based on the medical record of patients received from January 1, 2017 to December 31, 2021 in the cancer department of Yalgado ouedraogo University Hospital. Patients followed for histologically confirmed breast cancer who were classified in the cT4 category of the TNM code 8e edition were included. We collected a total of 286 patients. Non-salaried patients accounted for 90.56%. In this study, 53.3% of patients lived in urban area and 36.7% in rural area. Menopausal patients accounted for 56.8% of cases. One hundred and thirty-three (46.5%) patients were overweight or obese and 121 (42.3%) patients had a normal weight. The average consultation time, which is the time between the first signs and consultation in a specialized center, was 12 months, with a median of 11 months. According to category T of the TNM code, 19 patients (6.6%) were classified T4d, 176 (61.5%) were classified T4c, 69 (24.1%) were classified T4b and 22 (7.7%) T4a. One hundred and twenty patients (42%) were metastatic. The median overall survival of all patients in our sample was 20 months. In univariate analysis, metastatic status was risk factor for death, while obesity and surgery were protective factors. In multivariate analysis, obesity, surgery and metastatic status were independently associated with survival;obesity and surgery were protective factors. Survival is poor due to advanced stages and difficulties in the management of these cancers. Measures to facilitate access to care would improve the prognosis of these cancers.
