Investigations into the association between diabetic nephropathy (DN) and MTHFR C677T gene polymorphism in several case–control
studies has yielded contradictory results. To shed light on these inconclusive findings, a meta-analysis of all available
studies relating the C677T polymorphism to the risk of developing DN was conducted. The PubMed database was searched, and
case–control studies investigating the association between MTHFR C677T gene polymorphism and DN were included in the meta-analysis.
The meta-analysis included 15 studies, of which 8 involved Caucasians and 5 East Asians; 11 studies involved subjects with
type 2 diabetes and 4 with type 1 diabetes. The main analysis (all studies) revealed significant heterogeneity between the
studies (P
Q < 0.01) and a marginal association between the 677T allele and the risk of developing DN; the random effects (RE) pooled
odds ratio (OR) was 1.30 (1.03–1.64). However, the sensitivity analysis (exclusion of studies not in Hardy–Weinberg equilibrium)
produced non-significant results. The recessive model derived significant results in main analysis [fixed effects (FE) OR = 1.32
(1.10–1.58), P
Q = 0.27], and in type 2 diabetes [FE OR = 1.30 (1.06–1.60), P
Q = 0.38]. The additive model produced significant association in main analysis [RE OR = 1.65 (1.13–2.42), P
Q < 0.01] in Caucasians [FE OR = 1.48 (1.11–1.98), P
Q = 0.17] and in type 2 diabetes [RE OR = 1.65 (1.03–2.67), P
Q < 0.01]. However, sensitivity analysis diminished the significant results in type 2 diabetes. There is no differential magnitude
of effect in large versus small studies. In conclusion, although there is some evidence of association between MTHFR C677T
gene polymorphism and DN, the above findings reinforce the need for further and more rigorous association studies. 相似文献

ObjectivesThis qualitative study aimed to gain insight from the perspectives of food insecure African Americans living in an inner city regarding important diabetes intervention strategies and components.MethodsUsing a grounded theory approach, two focus groups (totaling 16 individuals) were conducted in Milwaukee, Wisconsin. Purposive, convenience sampling was used to identify food insecure adults with diabetes. Questions were asked using a moderator guide to explore challenges and barriers to managing diabetes within the context of food insecurity, and facilitators or resources that helped participants improve diabetes management. Questions were open ended and followed by probes asking for additional perspectives and personal experiences related to the overarching topic, and questions asking to clarify statements.ResultsOverarching concepts and themes specific to possible interventions discussed during the focus groups included group education, peer support, access to community resources and programs, stress management, and faith-based programs as desired intervention outcomes.ConclusionsKey findings from the current study show that inner-city African Americans with diabetes desire interventions that foster social and community support systems.Practice ImplicationsGiven this insight, more robust and comprehensive interventions are needed to account for the multifaceted experience of food insecurity and diabetes within the inner-city environment. 相似文献

BackgroundMany risk factors contribute to the pathogenesis of diabetes. Gene and lifestyle factors are considered to be the major contributors. A dietary pattern is attributed to be one of the lifestyle risk factors favoring diabetes. The present study aims to find an association between fatty acid desaturase (FADS) gene polymorphism and glycemic profile in type 2 diabetes mellitus (T2DM).MethodologyA total of 429 subjects were included in the study on the basis of inclusion and exclusion criteria, of which 213 and 216 subjects were diabetic and control, respectively. Body mass index was calculated. Fasting plasma glucose, glycated hemoglobin (HbA1c) and insulin were measured using commercially available kits. rs174575 of FADS2 was selected based on previous publications and identified using the dbSNP database. To compare the biochemical parameters with the genotype, the following three models were used: additive model (CC vs CG vs GG), dominant model (CC + CG vs GG), and recessive model (CC vs CG + GG).Results and DiscussionFBS, HbA1c, insulin, HOMA-IR, and HOMA-B exhibited a high and statistically significant difference between subjects and controls. The three models exhibited a statistically significant difference between FBS, HOMA-IR, and HOMA- B (p<0.05).ConclusionThe distribution of rs174575 genotype differed significantly between the subjects and controls in the present study. The study revealed that genetic variation in FADS2 is an additional facet to consider while studying the risk factors of T2DM. 相似文献

Monocyte chemoattractant protein-1 (MCP-1) is suggested to be involved in the progression of diabetic nephropathy. We investigated the association of the -2518 A/G polymorphism in the MCP-1 gene with progressive kidney failure in Korean patients with type 2 diabetes mellitus (DM). We investigated -2518 A/G polymorphism of the MCP-1 gene in type 2 DM patients with progressive kidney failure (n=112) compared with matched type 2 DM patients without nephropathy (diabetic control, n=112) and healthy controls (n=230). The overall genotypic distribution of -2518 A/G in the MCP-1 gene was not different in patients with type 2 DM compared to healthy controls. Although the genotype was not significantly different between the patients with kidney failure and the diabetic control (p=0.07), the A allele was more frequent in patients with kidney failure than in DM controls (42.0 vs. 32.1%, p=0.03). The carriage of A allele was significantly associated with kidney failure (68.8 vs. 54.5%, OR 1.84, 95% CI 1.07-3.18). In logistic regression analysis, carriage of A allele retained a significant association with diabetic kidney failure. Our result shows that the -2518 A allele of the MCP-1 gene is associated with kidney failure in Korean patients with type 2 DM. 相似文献

Association between the GLUT1 gene polymorphism and the risk of diabetic nephropathy: a meta-analysis 总被引:5,自引:1,他引:5
The association between diabetic nephropathy (DN) and the XbI polymorphism in the GLUT1 gene has been investigated in several case-control studies. These studies rendered contradictory results: the allele XbI(–) was shown either to be a risk factor or neutral, or even protective for the development of the disease. To shed some light on these inconclusive findings, a meta-analysis of all available studies relating the XbI polymorphism to the risk of developing DN was conducted. Five out of six identified studies included Caucasian populations, and only one involved samples from an Asian population. Overall, the meta-analysis suggested large heterogeneity between studies (P<0.01, I2=68%) and lack of association between allele XbI(–) and the risk of developing DN relative to allele XbI(+): random effects odds ratio (OR)=1.26 [95% CI (0.93, 1.69)]. Excluding one study with the controls not in Hardy–Weinberg equilibrium, the sensitivity analysis revealed that heterogeneity (P=0.28, I2=21%) could be explained, and then, there is an overall association: fixed effects OR=1.34 [95% CI (1.13, 1.60)]. Then, significant ORs were also found on analysis of subgroups: for the Caucasian population, fixed effects OR=1.29 [95% CI (1.08, 1.56)] and for the type 2 diabetic patients fixed effects OR=1.69 [95% CI (1.09, 2.63)]. In type 1 diabetes, there is a moderate heterogeneity (P=0.19, I2=41%) with fixed effects OR=1.29 [95% CI (1.06, 1.56)] and random effects OR=1.32 [95% CI (1.01, 1.71)]. There is a source of bias in the selected studies: large studies failed to show association while small studies claimed an association. Although there is evidence of association between GLUT1 and DN, the above findings reinforce the need for further and more rigorous association studies. 相似文献

We evaluated the relationship of an alanine or valine polymorphism at amino acid sequence 16 [Val(16)Ala] of manganese superoxide
dismutase (Mn-SOD) with diabetes and diabetic nephropathy in Japanese type 2 diabetic patients. Val(16)Ala genotyping of Mn-SOD
was done by polymerase chain reaction-restriction fragment length polymorphism with a restriction enzyme (Bsaw I) in 478 Japanese type 2 diabetic patients and 261 nondiabetic Japanese healthy subjects. The genotype distribution of
diabetic and nondiabetic subjects was then compared, and the association of genotype with diabetic nephropathy was evaluated
in the diabetic patients. The allele frequency and genotype of the diabetic patients were not different from those of the
healthy nondiabetic subjects. The VV type showed a significantly higher frequency in the diabetic patients with nephropathy
than did the AA or VA type [VV type: normoalbuminuria 70.8%, microalbuminuria 84.8% (P = 0.0057), macroalbuminuria 84.1% (P
= 0.0128)]. Furthermore, logistic regression analysis showed that this polymorphism is associated with diabetic nephropathy
independently (odds ratio = 0.461925, P = 0.03). Accordingly, the Val(16)Ala polymorphism of Mn-SOD may be unrelated to the
etiology of type 2 diabetes, but it seems to be associated with diabetic nephropathy in Japanese type 2 diabetic patients.

The microsomal triglyceride transfer protein (MTP) is required for the assembly and secretion of apolipoprotein B-containing lipoproteins. Emerging evidence has indicated that the functional MTP exon polymorphism I128T is associated with dyslipidemia and other traits of the insulin-resistance syndrome, and the T128 variant seems to confer a reduced stability of MTP, resulting in reduced binding of LDL particles. The aim of the study was to elucidate the association of this MTP polymorphism with parameters of postprandial metabolism. A total of 716 male subjects from a postprandially characterized cohort (MICK) and a nested case–control study (EPIC) of 190 incident type 2 diabetes cases and 380 sex- or age-matched controls were genotyped for the I128T exon polymorphism. In comparison to homozygote subjects of the wild allele, carriers of the less common allele of the MTP T128 genotype showed significantly lower postprandial insulin levels (P=0.017), lower diastolic blood pressure (P=0.049) and had a lower prevalence of impaired glucose metabolism and diabetes type 2 (P=0.03) in the MICK. Consistent with this, we found a lower incidence of type 2 diabetes in male subjects of the nested case–control study in the T128 genotype (P=0.007). These results suggest that the rare allele of the MTP I128T polymorphism may be protective against impaired glucose tolerance, type 2 diabetes and other parameters of the metabolic syndrome. 相似文献

The association between retinopathy in type 2 diabetes [diabetic retinopathy (DR)] and the C677T polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene has been investigated in several case-control studies. These studies rendered contradictory results, some indicating that the polymorphism is associated with the risk of developing DR whereas others concluded there is no association. To shed light on these inconclusive findings, a meta-analysis of all available studies relating the C677T polymorphism to the risk of developing DR was conducted. Four out of five identified studies included populations of East Asian descent, and only one involved samples from European descent (Caucasians). Overall, the meta-analysis suggested large heterogeneity between studies (p = 0.08, I2 = 52%) and marginal association between C677T transition and the risk of developing DR: random effects odds ratio (OR) = 1.39 [95% CI (1.05, 1.83)]. The sensitivity analysis [exclusion of one East Asian study with the controls not in Hardy–Weinberg equilibrium (HWE)] showed no heterogeneity (p = 0.25, I2 = 27%) and no significant association: fixed effects OR = 1.22 [95% CI (0.99, 1.51)] and random effects OR = 1.24 [95% CI (0.96, 1.60)]. The sub-group analysis for the East Asian population produced a significant association: fixed effects OR = 1.48 [95% CI (1.20, 1.83)] and random effects OR = 1.52 [95% CI (1.14, 2.03)]. However, sensitivity analysis in East Asians revealed that the association is marginal: fixed effects OR = 1.33 [95% CI (1.04, 1.70)] and random effects OR = 1.36 [95% CI (1.01, 1.83)]. There is a source of bias in the selected studies: the largest studies failed to show association while the smallest study claimed an association. The above findings reinforce the need for larger and more rigourous studies in this area. 相似文献

Variants in the engulfment and cell motility 1 (ELMO1) gene are associated with nephropathy due to type 2 diabetes mellitus (T2DM) in a Japanese cohort. We comprehensively evaluated this gene in African American (AA) T2DM patients with end-stage renal disease (ESRD). Three hundred and nine HapMap tagging SNPs and 9 reportedly associated SNPs were genotyped in 577 AA T2DM-ESRD patients and 596 AA non-diabetic controls, plus 43 non-diabetic European American controls and 45 Yoruba Nigerian samples for admixture adjustment. Replication analyses were conducted in 558 AA with T2DM-ESRD and 564 controls without diabetes. Extension analyses included 328 AA with T2DM lacking nephropathy and 326 with non-diabetic ESRD. The original and replication analyses confirmed association with four SNPs in intron 13 (permutation p-values for combined analyses = 0.001–0.003), one in intron 1 (P = 0.004) and one in intron 5 (P = 0.002) with T2DM-associated ESRD. In a subsequent combined analysis of all 1,135 T2DM-ESRD cases and 1,160 controls, an additional 7 intron 13 SNPs produced evidence of association (P = 3.5 × 10−5 – P = 0.05). No associations were seen with these SNPs in those with T2DM lacking nephropathy or with ESRD due to non-diabetic causes. Variants in intron 13 of the ELMO1 gene appear to confer risk for diabetic nephropathy in AA. 相似文献
