Lack of association between genetic variants in the 19q13.32 region and CHD risk in the Algerian population: a population-based nested case-control study.

Background: Coronary Heart Disease (CHD) is a major cause of morbidity and mortality over the world; intermediate traits associated with CHD commonly studied can be influenced by a combination of genetic and environmental factors.

Objective: We found previously significant association between three genetic polymorphisms, and the lipid profile variations in the Algerian population. Considering these findings, we therefore decided to assess the relationships between these polymorphisms and CHD risk.

Prevalence of Metabolic Syndrome and its Related Risk Factors in the City of Oran, Algeria: the ISOR Study.

Background: Aging and lifestyle changes had led to an epidemiological transition, with a significant impact on the incidence of cardiovascular diseases in North Africa.

Objective: The aim of this study was to determine the prevalence of metabolic syndrome and its associated factors, which were unknown, among an urban population in Algeria.

Methods: During 2007-2009, 787 individuals aged 30-64 years, randomly selected from the list of insured persons residing in the city of Oran, participated in a clinical, anthropometric and biological survey.

Association analysis of the IL-1 gene cluster polymorphisms with aggressive and chronic periodontitis in the Algerian population.

Objective: There is strong evidence that genetic as well as environmental factors affect the development of periodontitis. Various studies suggest that genetic polymorphisms of the interleukin-1 (IL-1) genes are associated with an increased risk of developing the pathogenesis. The aim of the present study was to investigate the possible relationship between two polymorphisms of IL-1 gene cluster IL-1B (C+3954T) (rs1143634) and IL-1A (C-889T) (rs1800587) SNPs and the aggressive and chronic periodontitis risk in a case control study in Algerian population.

Associations of common SNPs in the SORT1, GCKR, LPL, APOA1, CETP, LDLR, APOE genes with lipid trait levels in an Algerian population sample.

Genome-wide association studies have identified many lipid-associated loci primarily in European and Asian populations. In view of the differences between ethnic groups in terms of the frequency and impact of these variants, our objective was to evaluate the relationships between eight lipid-associated variants (considered individually and in combination) and fasting serum triglyceride, total cholesterol, HDL- and LDL-cholesterol levels in an Algerian population sample (ISOR study, n = 751). Three SNPs (in SORT1, CETP and GCKR) were individually associated with lipid level variations.

Examination of the brain natriuretic peptide rs198389 single-nucleotide polymorphism on type 2 diabetes mellitus and related phenotypes in an Algerian population.

Background: In European populations, the NPPB rs198389 single nucleotide polymorphism (SNP) is associated with a reduced risk of type 2 diabetes mellitus (T2DM). We investigated the putative associations between NPPB rs198389, the T2DM risk and quantitative metabolic traits in an Algerian population.

Methods: The association analysis was performed as a T2DM case-control study (with 78 cases and 645 controls) nested into the ISOR population-based study.

The TCF7L2 rs7903146 polymorphism, dietary intakes and type 2 diabetes risk in an Algerian population.

Background: The transcription factor 7-like 2 (TCF7L2) gene is the most significant genetic risk factor for type 2 diabetes (T2D). Association analyses were performed on participants (n = 751, aged between 30 and 64) in the ISOR population-based study in the city of Oran. Dietary intakes were estimated using a weekly food frequency questionnaire.

Combined effect of established BMI loci on obesity-related traits in an Algerian population sample.

Background: Genome-wide association studies have identified variants associated with BMI in populations of European descent. We sought to establish whether genetic variants that are robustly associated with BMI could modulate anthropometric traits and the obesity risk in an Algerian population sample, the ISOR study.

Results: We found that each additional risk allele in the GPS was associated with an increment in the mean [95% CI] for BMI of 0.

Impact of APOE gene polymorphisms on the lipid profile in an Algerian population.

Background: The importance of apolipoprotein E (APOE) in lipid and lipoprotein metabolism is well established. However, the impact of APOE polymorphisms has never been investigated in an Algerian population. This study assessed, for the fist time, the relationships between three APOE polymorphisms (epsilon, rs439401, rs4420638) and plasma lipid concentrations in a general population sample from Algeria.
