The impact of the AHSG genetic polymorphism on the risk of ischemic stroke: a case-control study.

ABSTRACT: Ischemic stroke (IS) is a complex disease caused by an obstruction within a brain-supplying blood vessel that involves both genetic and environmental factors. In this study, we evaluated the association of genetic polymorphisms in the AHSG gene with ischemic stroke risk in the Chinese population. A case-control study was conducted that included 477 nephropathy patients and 490 healthy controls. Chi-squared tests and a genetic model were used to evaluate associations. In the genetic model analysis, we identified that the SNP of rs2070634 in the AHSG gene was associated with a 1.37-fold increase the risk of stroke in the co-dominant model (adjusted, the "G/T" genotype), and a 1.40-fold increase the risk of stroke in the Over-dominant model (adjusted, the "G/T" genotype), respectively. The rs2518136 in the AHSG gene was associated with a 1.37-fold increase the risk of stroke in the co-dominant model (adjusted, the "T/C" genotype) and a 1.41-fold decrease the risk of stroke in the over-dominant model (adjusted, the "T/C" genotype), respectively. We found four SNPs (rs2248690, rs2070634, rs4917 and rs2518136) show a strong linkage, but the AHSG haplotype was not found to be associated with a risk of ischemic stroke. The present study suggests that the AHSG polymorphism may contribute to an increased risk of ischemic stroke.

Project description:Background and objectives: Siesta, which is a short afternoon nap, is a habit that is commonly practiced in the Mediterranean and tropical areas. Data on the association between siesta and coronary artery disease has been conflicting. A protective effect has been demonstrated in the countries that commonly practice siesta, but a harmful effect has been observed in the countries that infrequently practice the siesta habit. Information on the association between siesta and ischemic stroke has been, however, lacking. Hence, the purpose of our study was to determine the effect of siesta on ischemic stroke. Materials and Methods: This was a case-control study, conducted on the patients with acute ischemic stroke who came for their first follow-up visit to the neurology clinic. Controls were randomly selected from the patients visiting the neurology clinic on the same day as the patients with ischemic stroke. In addition to basic demographics and the occurrence of established stroke risk factors, information about siesta practice was also collected from both groups. A multivariate logistic regression analysis was utilized to determine the relationship between siesta practice and ischemic stroke. Results: A total of 206 patients were recruited from the neurology clinic of King Khalid university hospital; of which only 194 subjects were included in the analysis (98 ischemic stroke cases and 96 controls). The mean age of the participants was 59.68 ± 13.75 years and 98 (50.52%) were male. Interestingly, 43% of the whole study cohort practiced regular siesta. However, when compared to the stroke population, the control group practiced siesta more frequently (30% vs. 56%). In a multivariate logistic regression analysis, hypertension, diabetes mellitus, excess body weight (body mass index > 25 kg/m2) and dyslipidemia were found to increase the risk of ischemic stroke (OR 2.12, 95% CI: 1.02-4.66, p = 0.005; OR 2.72, 95% CI: 1.94-4.88, p = 0.014; OR 2.94, 95% CI: 1.5164-5.7121 p = 0.0014; OR 3.27, 95% CI: 2.42-5.199, p ? 0.001, respectively). On the contrary, the practice of regular siesta lowered the risk of ischemic stroke (OR 0.58, 95% CI: 0.3551-0.9526, p = 0.031). Conclusions: Siesta was associated with a reduced risk for the occurrence of ischemic stroke. Large prospective longitudinal studies should be conducted to verify the protective effect of siesta on stroke.

Project description:BACKGROUND AND PURPOSE:Stroke is a multifactorial disease influenced by both genetic and environmental factors. The aim of this case-control study was to determine the association between ?-fibrinogen C148T (rs1800787) gene polymorphism and susceptibility to ischemic stroke (IS) in a North Indian population. METHODS:In the present case-control study, genotyping was performed using the PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) method on 250 IS patients and 250 age- and sex-matched controls. Frequency distributions of genotypes and alleles were compared between the cases and controls by conditional logistic regression. RESULTS:Hypertension, diabetes, dyslipidemia, low socioeconomic status, and family history of stroke were found to be independent risk factors for IS. The mean age of the cases and controls was 52.83 ± 12.59 and 50.97 ± 12.70 years, respectively. Multivariate logistic regression analysis showed an independent association between ?-fibrinogen C148T (rs1800787) polymorphism and risk of IS in dominant (OR = 2.19; 95% CI 1.23-3.90; p = 0.007) and allelic (OR = 1.66; 95% CI 1.19-2.33; p = 0.002) models. Based on the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification, an independent association of small vessel disease with risk of IS was observed in the dominant (OR = 2.09; 95% CI 1.10-3.96; p = 0.02) and allelic (OR = 1.75; 95% CI 1.12-2.75; p = 0.01) models, and a significant association of cardioembolic stroke with risk of IS was seen in the allelic model (OR = 2.11; 95% CI 1.07-4.17; p = 0.02). All the genotype frequencies observed were in accordance with Hardy-Weinberg equilibrium in both cases and controls. CONCLUSION:The findings of the present study suggest that polymorphism in the C148T position of the ?-fibrinogen gene might be a risk factor for IS mainly for the small vessel disease stroke subtype in a North Indian population. Further, large prospective studies are required to confirm these findings.
