Eleven susceptibility loci for late-onset Alzheimer's disease (LOAD) were identified by previous studies; however, a large portion of the genetic risk for this disease remains unexplained. We conducted a large, two-stage meta-analysis of genome-wide association studies (GWAS) in individuals of European ancestry. In stage 1, we used genotyped and imputed(More)
The only recognized genetic determinant of the common forms of Alzheimer's disease (AD) is the epsilon 4 allele of the apolipoprotein E gene (APOE). To identify new candidate genes, we recently performed transcriptomic analysis of 2741 genes in chromosomal regions of interest using brain tissue of AD cases and controls. From 82 differentially expressed(More)
Abstract. Although consequences of malaria in pregnancy are well known, the period of pregnancy in which infection has the highest impact is still unclear. In Benin, we followed up a cohort of 1,037 women through pregnancy until delivery. The objective was to evaluate the relationship between the timing of infection and birth weight, and maternal anemia at(More)
Apolipoprotein E (APOE) dependent lifetime risks (LTRs) for Alzheimer Disease (AD) are currently not accurately known and odds ratios alone are insufficient to assess these risks. We calculated AD LTR in 7351 cases and 10 132 controls from Caucasian ancestry using Rochester (USA) incidence data. At the age of 85 the LTR of AD without reference to APOE(More)
OBJECTIVE Several lines of evidence indicate that a decrease in the CSF concentration of amyloid beta(42) (Abeta(42)) is a potential biomarker for incident Alzheimer disease. In contrast, studies on plasma Abeta(1-40) and Abeta(1-42) peptide levels have yielded contradictory results. Here, we explored the links between incident dementia and plasma(More)
OBJECTIVE To examine the association of plasma cholesterol levels, lipid-lowering agent (LLA) intake, and APOE genotype with dementia prevalence. METHODS The Three-City Study is a population-based cohort of 9,294 subjects selected from the electoral rolls of three French cities (Bordeaux, Dijon, Montpellier). Baseline examination included extensive(More)
In malaria-endemic areas, infants are relatively protected against malaria infection. Such protection is though to be related principally to the transplacental transfer of maternal antibodies. We measured total and Plasmodium falciparum-specific IgG (including subclasses), IgM, and IgE antibodies in 154 paired maternal-cord serum samples from an area of(More)
The consequences of pregnancy-associated malaria on a child's health have been poorly investigated. Malarial infection of the placenta seems to result in a higher susceptibility of children to the parasite during their first year of life. In 1993-1995, the authors investigated the role of antibodies in variable surface antigens (VSA) specific to chondroitin(More)
Mechanisms responsible for the increase in malaria susceptibility during pregnancy, and in particular during the first pregnancy, have not been elucidated. T and B cell responses to leucoagglutinin, bacille Calmette-Guerin (BCG) and to six Plasmodium falciparum antigens were longitudinally investigated in 33 pregnant women during their first pregnancy,(More)
BACKGROUND Few studies have evaluated the effect of malaria on intrauterine growth restriction on the basis of the fetal growth rate, rather than just the small-for-gestational age z score. Here, we assessed the impact of malaria on IUGR, using data from a longitudinal, ultrasonography-based follow-up study of Beninese women. METHODS A total of 1016 women(More)
