No full textVitamin D deficiency and VDR TaqI polymorphism on diabetic nephropathy risk among type 2 diabetes patients
No full textBackgroundMany studies have shown that vitamin D deficiency and vitamin D receptor TaqI gene polymorphisms are associated with susceptibility to diabetic nephropathy in various populations. The objective of this study was to determine the impact of vitamin D deficiency and vitamin D receptor TaqI gene polymorphism on the risk of diabetic nephropathy complications in T2DM at the Debre Tabor Comprehensive Specialized Hospital, Northwest EthiopiaMethodsA total of 210 participants, including 70 diabetic patients with nephropathy, 70 diabetic patients without nephropathy, and 70 healthy controls, participated in an age—and sex-matched hospital-based case-control study. Demographic and clinical data were assessed to determine the related risk factors. DNA was extracted from blood samples and subjected to polymerase chain reaction and agarose gel electrophoresis analysis to determine the TaqI genotypes.ResultsVitamin D deficiency was detected in our investigation, and it was much more prevalent in diabetic nephropathy patients than type 2 diabetic patients and controls (OR = 5.05, 95% CL = 2.03–12.53; P < 0.001). Moreover, both the TaqI tt genotype (OR: 2.48; 95% CL: 1.15-5.37; P=0.020) and t allele (OR: 1.70; 95% CL: 1.13-2.57; P=0.010) were substantially more prevalent in diabetic nephropathy patients than in type 2 diabetic patients and controls, indicating that it may be a major risk factor for the development of diabetic nephropathy.ConclusionsThe findings point to a potential link between vitamin D deficiency and diabetic nephropathy complications. Moreover, TaqI gene polymorphisms have been linked to an increased risk of developing the disease in the Ethiopian population under study
Association between angiotensinogen M235T gene polymorphism and risk of ischemic stroke among the Ethiopian population: a case control study
No full textIschemic stroke (IS) is a multifaceted, complicated illness resulting from a confluence of genetic, environmental and vascular risk factors. Many genes that may contribute to ischemic stroke have been discovered in humans. The genetic contribution appears to be greater in IS patients with hypertension. There is conflicting evidence about a positive correlation between the AGT M235T polymorphism and ischemic stroke. The aim of this study was to examine the possible association of the AGT M235T gene polymorphism with the risk of ischemic stroke. A hospital-based case-control study was carried out in 36 ischemic stroke patient cases and 36 age- and sex-matched healthy controls. Clinical parameters were measured to assess the associated risk factors. DNA was isolated from blood samples, and the AGT M235T genotypes were identified using polymerase chain reaction (PCR) and analyzed by agarose gel electrophoresis. The AGT-TT genotype (OR = 4.64, 95% CL = 1.23–17.4; p = 0.023 and T allele (OR = 2.54, 95% CL = 1.28–5.02; p = 0.003) were significantly more common in patients than in controls, indicating that it may be a major risk factor for the development of ischemic stroke. The results suggest that there may be a significant correlation between the AGT M235T gene polymorphism and the development of ischemic stroke in the studied Ethiopian population
