PPARG and ADIPOQ gene polymorphisms increase type 2 diabetes mellitus risk in Asian Indian Sikhs: Pro12Ala still remains as the strongest predictor

Aim. To analyze the association of genotype combinations of the polymorphic markers G276T in the ADIPOQ gene, Glu23Lys in the KCNJ11 gene, and IVS3C>T in the TCF7L2 gene with the development of type 2 diabetes mellitus (T2DM) in the Kyrgyz population. Subjects and methods. The investigation enrolled 23 Kyrgyz people, of whom there were 114 patients with T2DM and 109 without T2DM (a control group). T2DM was diagnosed in accordance with the WHO criteria (1999). The genotypes of ADIPOQ (G276T), KCNJ11 (Glu23Lys), and TCF7L2 (IVS3C>T) gene polymorphisms were identified using the restriction fragment length polymorphism analysis. Results. When typing at the polymorphic loci G276T in the ADIPOQ gene, Glu23Lys in the KCNJ11 gene, and IVS3C>T in the TCF7L2 gene, the development of T2DM in the Kyrgyz population was associated with the T allele (odds ratio (OR), 1.68; p=0.025), the heterozygous G276T genotype (OR 1,8; p=0.036) in the ADIPOQ gene; the 23Lys allele (OR, 1.62; p=0.019) in the KCNJ11 gene; a two-locus genotype combination in the genes ADIPOQ/KCNJ11: G276T/Glu23Lys (OR, 4.88; p=0.0013), G276G/Lys23Lys (OR, 4.65; p=0.019), G276T/Glu23Glu (OR, 3.10; p=0.022), a two-locus genotype combination in the genes ADIPOQ/TCF7L2: G276T/СС (OR, 1.97; p=0.04); two-locus genotype combinations in the genes KCNJ11/TCF7L2: Lys23Lys/CC (ОR, 2.65; p=0.042), Glu23Lys/CT (OR, 3.88; p=0.027); and a three-locus genotype combination in the genes ADIPOQ/KCNJ11/TCF7L2: G276T/Glu23Lys/CT (OR, 14.48; p=0.02). Conclusion. The development of T2DM in the Kyrgyz population is genetically determined by ADIPOQ (G276T) gene, KCNJ11 (Glu23Lys), and TCF7L (IVS3C>T) gene polymorphisms with the predisposing value of the T allele of the heterozygous G276T genotype in the ADIPOQ gene; the 23Lys allele in the KCNJ1 gene; as well as by genotype combinations in the genes ADIPOQ/KCNJ11 (G276T/Glu23Lys, G276G/Lys23Lys, G276T/Glu23Glu); ADIPOQ/TCF7L2 (G276T/SS); KCNJ11/TCF7L2 (Lys23Lys/CC, Glu23Lys/CT); ADIPOQ/KCNJ11/TCF7L2 (G276T/Glu23Lys /CT). The IVS3C>T locus in the TCF7L2 gene is not independently statistically significantly associated with the development of T2DM; however, its predisposing effect has been identified in its combination with the variant genotypes of the polymorphic loci G276T in the ADIPOQ gene and Glu23Lys in the KCNJ11 gene.

Diabetes Mellitus Risk

Background: Studies show that diabetes mellitus is the greatest lifestyle risk factor for dementia. Appropriate management and treatment of type 2 diabetes mellitus could prevent the onset and progression of mild cognitive impairment to dementia. MoCA test is high sensitivity with mild dementia but it have not been used and studied widespread in Vietnam. Aim: 1. Using MoCA and MMSE to diagnose dementia in patients with type 2 diabetes mellitus. 2. Assessment of the relationship between dementia and the risk factors. Methods: cross-sectional description in 102 patients with type 2 diabetes mellitus. The Mini-Mental State Examination(MMSE) and the Montreal Cognitive Assessment (MoCA) were used to assess cognitive function. The diagnosis of dementia was made according to Diagnostic and Statistical Manual of Mental Disorders. Results: The average value for MoCA in the group of patients with dementia (15.35 ± 2.69) compared with non-dementia group (20.72 ± 4.53). The sensitivity and specificity of MoCA were 84.8% and 78.3% in identifying individuals with dementia, and MMSE were 78.5% and 82.6%, respectively. Using DSMIV criteria as gold standard we found MoCA and MMSE were more similar for dementia cases (AUC 0.871 and 0.890). The concordance between MoCA and MMSE was moderate (kappa = 0.485). When considering the risk factors, the education,the age, HbA1c, dyslipidemia, Cholesterol total related with dementia in the type 2 diabetes. Conclusion: MoCA scale is a good screening test of dementia in patients with type 2 diabetes mellitus.When compared with the MMSE scale, MoCA scale is more sensitive in detecting dementia.
