Mutations in exon 11 (11.1 and 11.2) of the gene and risk factors for breast cancer in Burkina Faso.

Breast cancer is the leading cause of death among women in both developed and developing countries. It is multifactorial, including genetic predispositions such as oncogenic mutations on and 2 genes. The objectives of the present study were to identify oncogenic mutations in exon 11 of the gene and to determine the risk factors for breast cancer among women population in Burkina Faso.

Breast cancer in West Africa: molecular analysis of BRCA genes in early-onset breast cancer patients in Burkina Faso.

Background: Breast cancer (BC) is the most commonly diagnosed cancer and the second leading cause of cancer-related deaths among women in Africa after cervical cancer. Even if the epidemiological data are now aligned with those relating to industrialized countries, the knowledge concerning breast cancer in Africa, particularly in Western Africa, still lack clinical data, medical treatments, and the evaluation of genetic and non-genetic factors implicated in the etiology of the disease. The early onset and the aggressiveness of diagnosed breast cancers in patients of African ancestry strongly suggest that the genetic risk factor may be a key component, but so far, very few studies on the impact of germ line mutations in breast cancer in Africa have been conducted, with negative consequences on prevention, awareness and patient management.

Carriage of HLA-DRB1*11 and 1*12 alleles and risk factors in patients with breast cancer in Burkina Faso.

Several factors contribute to the development of breast cancer, including the immune system. This study is aimed to characterize the carriage of human leukocyte antigen (HLA)-DRB1*11 and 1*12 alleles in patients with breast cancer. This case-control study consisted of 96 histologically diagnosed breast cancer cases and 102 controls (cases without breast abnormalities).

Seroprevalence, Genotyping, and Monitoring of Hepatitis C Viral Loads in Patients on Antivirals in Burkina Faso.

Introduction: Hepatitis C virus (HCV) infection remains a major public health problem worldwide. In Burkina Faso, nearly 720,000 people are living with HCV, and each year about 900 people die from complications of cirrhosis or hepatocellular carcinoma. This study was planned to determine the HCV seroprevalence, characterize circulating genotypes, and monitor HCV viral loads in patients under treatment with antivirals.

Glutathione S-transferase M1 and T1 genes deletion polymorphisms and blood pressure control among treated essential hypertensive patients in Burkina Faso.

Objective: Glutathione S-transferases have been associated with experimental resistance to some drugs. The present study investigated the factors associated with blood pressure control in patients with essential hypertension, especially the role of GSTT1 and GSTM1 genes polymorphisms. This cross-sectional study in Burkina Faso consisted of 200 patients with essential hypertension and under treatment.

Molecular Epidemiology of Human Papillomaviruses, and among Female Sex Workers in Burkina Faso: Prevalence, Coinfections and Drug Resistance Genes.

Viral and bacterial infections represent an occupational risk for female sex workers. This study aimed at determining HPV coinfection with genital pathogens among female sex workers in West and Central Africa and identifying antibiotic resistance genes. A total of 182 samples from female sex workers were analyzed by real-time PCR and classic PCR.

Trends in contraceptive use, unmet need and associated factors of modern contraceptive use among urban adolescents and young women in Guinea.

Background: In Guinea, high fertility among adolescents and young women in urban areas remains a public health concern. This study describes trends in contraceptive use, unmet need, and factors associated with the use of modern family planning (FP) methods among urban adolescents and young women in Guinea.

Methods: We used four Guinea Demographic and Health Surveys (DHS) conducted in 1999, 2005, 2012, and 2018.

Genotypic distribution of human oncogenic papillomaviruses in sexually active women in Burkina Faso: Central, Central-Eastern and Hauts-Bassins regions.

Objective this study was conducted to determine the distribution of high-risk human papillomavirus (HR-HPV) genotypes in women in the general population of three regions of Burkina Faso. Method This multicenter, descriptive cross-sectional study involved 1321 sexually active women in five cities in three regions of Burkina Faso: Central, Central-Eastern and Hauts-Bassins regions. After collection of endocervical specimens, pre-cervical lesions were screened by visual inspection with acetic acid and lugol (VIA / VILI).

Polymorphism of MMP1 and MMP3 promoter regions and HR-HPV infection in women from Burkina Faso and Côte d'Ivoire.

The single nucleotide polymorphism (SNP) of the promoter region of MMP-1 (at 1607 bp) and MMP-3 (at 1171 bp) create Ets binding sites. Correlations between these SNPs and sensitivity to several biological processes such as metastasis and recurrence of cancer have been reported in several studies. In this case-control study, we looked for these SNPs in women infected with or not with high-risk human papillomaviruses (HR-HPV).

Glutathione S-transferase M1 and T1 genes deletion polymorphisms and risk of developing essential hypertension: a case-control study in Burkina Faso population (West Africa).

Background: Glutathione S-transferases play a key role in the detoxification of persistent oxidative stress products which are one of several risks factors that may be associated with many types of disease processes such as cancer, diabetes, and hypertension. In the present study, we characterize the null genotypes of GSTM1 and GSTT1 in order to investigate the association between them and the risk of developing essential hypertension.

Methods: We conducted a case-control study in Burkina Faso, including 245 subjects with essential hypertension as case and 269 control subjects with normal blood pressure.

Positive association between ATP2B1 rs17249754 and essential hypertension: a case-control study in Burkina Faso, West Africa.
