Prevalence of high-risk human papillomavirus genotypes in outpatient Malian women living with HIV: a pilot study.

INTRODUCTION: Long-term exposure to high-risk human papillomavirus (Hr-HPV) is a well-known necessary condition for development of cervical cancer. The aim of this study is to screen for Hr-HPV using vaginal self-sampling, which is a more effective approach to improve women's adherence and increase screening rates. METHODS: This pilot study included a total of 100 Women living with HIV (WLWHIV), recruited from the Center for Listening, Care, Animation, and Counseling of People Living with HIV in Bamako. Hr-HPV genotyping was performed on Self-collected samples using the Cepheid GeneXpert instrument. RESULTS: The median age of WLWHIV was 44 (interquartile range [IQR], 37-50) years. Approximately 92% of the study participants preferred self-sampling at the clinic, and 90% opted to receive result notifications via mobile phone contact. The overall prevalence of Hr-HPV among study participants was 42.6%, and the most frequent Hr-HPV sub-types observed were HPV18/45 (19.1%), HPV31/35/33/52/58 (13.8%), and HPV39/68/56/66 (12.8%), followed by HPV16 (5.3%), and HPV51/59 (5.3%). WLWHIV under 35 years of age had a higher frequency of Hr-HPV compared to their older counterparts, with rates of 30% versus 11.1% (p = 0.03). The duration of antiretroviral treatment showed an inverse association with Hr-HPV negativity, with patients on treatment for 15 (IQR, 10-18) years versus 12 (IQR = 7-14) years for Hr-HPV positive patients (95% CI [1.2-5.8], t = 3.04, p = 0.003). WLWHIV with baseline CD4 T-Cell counts below 200 exhibited a higher frequency of Hr-HPV compared to those with baseline CD4 T-Cell counts above 200 (17.9% versus 1.9%, p = 0.009). However, other demographics and clinical factors, such as marital status, age of sexual debut, parity, education, history of abortion, history of preeclampsia, and cesarean delivery, did not influence the distribution of Hr-HPV genotypes. CONCLUSION: Our findings indicate that WLWHIV under the age of 35 years old exhibited the highest prevalence of Hr-HPV infection, with HPV18/45 being the most prevalent subtype. Additionally, WLWHIV with baseline CD4 T-Cell counts below 200 showed the highest infection rates.

Lack of Association of C677T Methylenetetrahydrofolate Reductase Polymorphism with Breast Cancer Risk in Mali.

Methylenetetrahydrofolate reductase (MTHFR) plays a major role in the metabolism of folates and homocysteine, which in turn can affect gene expression and ultimately promote the development of breast cancer. Thus, mutations in the MTHFR gene could influence homocysteine, methionine, and S-adenosylmethionine levels and, indirectly, nucleotide levels. Imbalance in methionine and S-adenosylmethionine synthesis affects protein synthesis and methylation. These changes, which affect gene expression, may ultimately promote the development of breast cancer. We therefore hypothesized that such mutations could also play an important role in the occurrence and pathogenesis of breast cancer in a Malian population. In this study, we used the PCR-RFLP technique to identify the different genotypic profiles of the C677T MTHFR polymorphism in 127 breast cancer women and 160 healthy controls. The genotypic distribution of the C677T polymorphism in breast cancer cases was 88.2% for CC, 11.0% for CT, and 0.8% for TT. Healthy controls showed a similar distribution with 90.6% for CC, 8.8% for CT, and 0.6% for TT. We found no statistical association between the C677T polymorphism and breast cancer risk for the codominant models CT and TT (p > 0.05). The same trend was observed when the analysis was extended to other genetic models, including dominant (p = 0.50), recessive (p = 0.87), and additive (p = 0.50) models. The C677T polymorphism of MTHFR gene did not influence the risk of breast cancer in the Malian samples.

The causes of death are of great importance in assessing the health status of the population and care'squality. Their study could guide health policies aimed at increasing life expectancy. OBJECTIVES: It was to determine the causes of death; to study the socio-demographic characteristics of deceased. MATERIALS AND METHODS: This was a retrospective and descriptive study of all deaths that occurred in the Medical Department of Sikasso Hospital from January 2018 to December 2020. RESULTS: Among 265 deaths recorded, the mean age was 45.12 ± 17.5 years. The sex ratio was 1.59. They were mostly city dwellers and 51.64% lived in Sikasso city. The mean length of hospitalization was 7.09 ± 6.38 days. Kidney failure was the first reason for hospitalization. HIV infection was the leading cause of death (29.8%), followed by renal failure (24.2%). The male sex was predominant in all causes of death except HIV infection and anemia. Deaths linked to kidney failure have increased fivefold from 2018 to 2020. CONCLUSION: Deaths related to HIV/AIDS remain in the lead despite their strong reduction; those related to kidney failure have increased fivefold.

Les causes de décès revêtent une grande importance dans l'évaluation de l'état de santé de la population et de la qualité des soins. Leur étude pourrait orienter les politiques de santé visant à accroître l'espérance de vie. OBJECTIFS: C'était de déterminer les causes de mort ; d'étudier les caractéristiques sociodémographiques des défunts. MATÉRIELS ET MÉTHODES: Il s'agissait d'une étude rétrospective et descriptive portant sur tous les décès survenus dans le service de Médecine de l'hôpital de Sikasso de Janvier 2018 à Décembre 2020. RÉSULTATS: Parmi 265 décès recensés, l'âge moyen était de 45,12±17,5 ans. Le sex-ratio était de 1,59. Il s'agissait en majorité de citadins et 51,64% résidaient à Sikasso ville. La durée moyenne d'hospitalisation était 7,09 ± 6,38 jours. L'insuffisance rénale constituait le 1er motif d'hospitalisation. L'infection à VIH était la 1ère cause de décès (29,8%), suivie de l'insuffisance rénale (24,2%). Le sexe masculin était majoritaire dans toutes les causes de décès hormis l'infection à VIH et l'anémie. Les décès liés à l'insuffisance rénale ont quintuplé de 2018 à 2020. CONCLUSION: Les décès liés au VIH/SIDA reste en tête malgré leur forte réduction ; ceux liés à l'insuffisance rénale ont quintuplé.
