    ABSTRACT: Background and Objective: Uric acid is a neuroprotective agent. However, its relationship with ischaemic stroke remains controversial. We analyzed the association between serum uric acid and ischemic stroke and clinical outcome. Methods: The study subject consisted of 550 ischemic stroke patients from the Nizam's Institute of Health Sciences, Hyderabad, India with 550 matched healthy controls. Serum uric acid levels were estimated, and follow-up interviews conducted with patients. Results: There was a significant association of elevated levels of serum uric acid with stroke and its subtypes except lacunar stroke. Patients with high serum uric acid levels had a significant increased risk of poor outcome. Conclusion: Serum uric acid level is associated with ischemic stroke, and is an independent prognostic factor of poor outcome.

    ABSTRACT: Genetic variants of cytochrome P450 4F2 (CYP4F2) gene have been suggested to be risk factors for hypertension, cardiovascular diseases and stroke. In the present case-control study we investigated the association of 1347 G/A polymorphism (rs2108622) in the 11th exon region of CYP4F2 gene with hypertension, ischemic stroke and stroke subtypes classified according to TOAST (Trial of Org 10172 in Acute Stroke Treatment) classification. Five hundred and seven stroke patients (hypertensives: normotensives = 279:228) and four hundred and eighty seven, age and sex matched controls (males: females = 356:131) (hypertensives: normotensives = 148:339) were involved in the study. The genotypes were determined by PCR-RFLP technique. Genotypes were confirmed by subjecting the PCR products to sequencing. Significant difference was observed in the genotypic distribution and allelic frequency between the stroke patients and healthy controls. AA genotype and A allele associated significantly with stroke and hypertension [P = 0.009; OR = 1.59 (95% CI = 1.119-2.283) and P = 0.010; OR = 1.26 (95% CI = 1.056-1.502); P = 0.01; OR = 1.58 (95% CI = 1.11-2.272) and P = 0.010; OR = 1.25(95% CI = 1.054-1.504) respectively]. A stepwise logistic regression analysis confirmed these findings. To establish that this polymorphism is associated with stroke independent of hypertension; we compared stroke patients without hypertension with normotensive controls. Significant difference was observed in genotypic distribution and allelic frequency between the two groups (P = 0.001 and 0.002 respectively). Evaluating the association of this polymorphism with stroke subtypes we found significant associations with cardioembolic stroke (P < 0.001). In conclusion our study suggests that 1347A allele of CYP4F2 gene is an important risk factor for hypertension and ischemic stroke.
