Association of lipid-lowering drugs, anti-diabetic drugs, non-steroidal anti-inflammatory drugs, and levodopa with age-related macular degeneration i…

2022

Purpose : Changes in lipid metabolism, chronic inflammation and increased oxidative stress have been discussed as patho-etiogenetic drivers in age-related macular degeneration (AMD). Systemic medication, such as lipid-lowering drugs (LLD) and anti-diabetic drugs, affect these pathways and may therefore also play a role in AMD pathogenesis. We aimed to investigate associations of commonly used systemic drugs with AMD prevalence in the European population.Methods : We included 38,694 adults from 14 population-based studies from the European Eye Epidemiology (E3) consortium. We performed multivariable logistic regression modelling to examine medication use association with prevalence of AMD as…

Association between IgM Anti-Herpes Simplex Virus and Plasma Amyloid-Beta Levels.

2011

International audience; OBJECTIVE: Herpes simplex virus (HSV) reactivation has been identified as a possible risk factor for Alzheimer's disease (AD) and plasma amyloid-beta (Aβ) levels might be considered as possible biomarkers of the risk of AD. The aim of our study was to investigate the association between anti-HSV antibodies and plasma Aβ levels. METHODS: The study sample consisted of 1222 subjects (73.9 y in mean) from the Three-City cohort. IgM and IgG anti-HSV antibodies were quantified using an ELISA kit, and plasma levels of Aβ(1-40) and Aβ(1-42) were measured using an xMAP-based assay technology. Cross-sectional analyses of the associations between anti-HSV antibodies and plasma …

Rare coding variants in PLCG2, ABI3, and TREM2 implicate microglial-mediated innate immunity in Alzheimer's disease

2017

International audience; We identified rare coding variants associated with Alzheimer's disease in a three-stage case-control study of 85,133 subjects. In stage 1, we genotyped 34,174 samples using a whole-exome microarray. In stage 2, we tested associated variants (P < 1 × 10-4) in 35,962 independent samples using de novo genotyping and imputed genotypes. In stage 3, we used an additional 14,997 samples to test the most significant stage 2 associations (P < 5 × 10-8) using imputed genotypes. We observed three new genome-wide significant nonsynonymous variants associated with Alzheimer's disease: a protective variant in PLCG2 (rs72824905: p.Pro522Arg, P = 5.38 × 10-10, odds ratio (OR) = 0.68…
