The critical role of calcium dyshomeostasis in the pathogenesis of Alzheimer’s disease(AD):AD is a progressive neurodegenerative disease characterized by cognitive decline,memory impairment,and behavioral *** an estimated 50 million people being affected worldwide,the incidence of AD is constantly increasing *** hallmark of AD is the accumulation of amyloid-beta protein(Aβ)in the form of amyloid plaques and hyperphosphorylated tau protein in the form of neurofibrillary ***,increasing evidence suggests that calcium ion(Ca2+)dysregulation also plays a crucial role in the pathogenesis of AD(Calvo-Rodriguez and Bacskai,2021).As a key second messenger,Ca2+regulates a wide range of cellular processes,including the release of neurotransmitters,gene expression,and cell ***^(2+)also regulates the activity of Calcium/calmodulin-dependent protein kinase II,which is critical for synaptic plasticity,learning,and memory(Kaushik et al.,2022).Alternation in the Ca^(2+)signal is an early event in the pathogenesis of AD,which can lead to synaptic dysfunction,neuronal loss,and cognitive impairment.

Introduction: Life expectancy improvement for people living with Human Immunodeficiency Virus (HIV) is coming up against the problems associated with aging and chronic diseases. Frailty is a concern affecting a growing number of patients, particularly the elderly in this population. Our study aimed to determine the prevalence of frailty and its predictors on people living with HIV aged 50 years and older followed at the Outpatient Treatment Clinic (CTA) in Dakar. Methodology: We conducted a cross-sectional study of descriptive and analytic purposes ranging from November 2022 to August 2023, in CTA, Dakar (Senegal). We included people living with HIV aged 50 years and older under antiretroviral therapy for at least 6 months (≥6 months). Frailty was considered according to Fried criteria with a score ≥3. To identify the predictors of frailty, we performed a multivariate logistic regression analysis using STATA software version 18. Results: We included 199 patients. The median age at the moment of the study was 58 years old [50 - 91] with a sex ratio (M/F) of 0.58. The most representative age group was that of [50 - 59] years (59.3%). HIV-1 profile was most common in 89.45%. The median duration under antiretroviral therapy was 180 months [6 - 284] and 94% of patients received a Tenofovir Disoproxil Fumarate (TDF)-containing regimen with 43% of them for at least 10 years. Viral load was undetectable (≤40 copies/ml) in 98% of cases. WHO Stage III was more common at inclusion and 55.78% had nadir TCD4+ Lymphocyte counts Conclusion: Our study confirms the high prevalence of frailty among older people living with HIV. Its prevention should consider the management of comorbidities and the implementation of non-pharmacological interventions such as nutrition.
