Diabetes mellitus (DM) affects about 9.3% of the population globally. Hyperhomocysteinemia (HHcy) has been implicated in the pathogenesis of DM, owing to its promotion of oxidative stress, β-cell dysfunction, and insulin resistance. HHcy can result from low status of one-carbon metabolism (OCM) nutrients (e.g., folate, choline, betaine, vitamin B6, B12), which work together to degrade homocysteine by methylation. The etiology of HHcy may also involve genetic variation encoding key enzymes in OCM. This review aimed to provide an overview of the existing literature assessing the link between OCM nutrients status, related genetic factors, and incident DM. We also discussed possible mechanisms underlying the role of OCM in DM development and provided recommendations for future research and practice. Even though the available evidence remains inconsistent, some studies support the potential beneficial effects of intakes or blood levels of OCM nutrients on DM development. Moreover, certain variants in OCM-related genes may influence metabolic handling of methyl-donors and presumably incidental DM. Future studies are warranted to establish the causal inference between OCM and DM and examine the interaction of OCM nutrients and genetic factors with DM development, which will inform the personalized recommendations for OCM nutrients intakes on DM prevention.

Background

Diabetic retinopathy is a common microvascular complication of diabetes mellitus (DM) and the leading cause of blindness in adults. Homocysteine, a risk factor with toxic effects on vascular endothelial cells, and bilirubin, a protectant with antioxidant and anti-inflammatory properties on the vasculature, have been reported to be linked to vaso-occlusive disorders. Therefore, the author of the present study investigated the association between the levels of plasma homocysteine and serum total bilirubin and the incidence of diabetic retinopathy as a chronic microvascular complication in patients with type 2 diabetes mellitus (T2DM).

Methods

A total of 102 patients with T2DM who visited our hospital from January 2009 to January 2010 were assessed.

Results

Of the 102 patients, the prevalence of diabetic retinopathy was 67 cases (65.7%) according to clinical ophthalmic examination. The duration of DM (P<0.001), age (P=0.003), fasting blood glucose (P=0.045) and urine albumin-creatinine ratio (P=0.015) in univariate analysis and plasma homocysteine level (P=0.038), duration of DM (P=0.001), and total bilirubin level (P=0.012) in multiple logistic regression analysis were statistically significantly associated with the incidence of diabetic retinopathy.

Conclusion

The present study indicates that homocysteine and bilirubin may be useful biomarkers for increased risk of diabetic retinopathy since retinopathy in patients with T2DM was linked to higher plasma homocysteine level and decreased serum total bilirubin level.

Background

Kidney function is critical in homocysteine clearance, and plasma homocysteine level is frequently increased in patients with renal failure. On the other hand, recent studies in animals have shown that hyperhomocysteinemia induces renal injury. In this study, we determined whether hyperhomocysteinemia can be a risk factor for the development of microalbuminuria in patients with type 2 diabetes.

Methods

A nested case-control study. Of 887 patients with type 2 diabetes who did not have microalbuminuria at baseline, 76 developed microalbuminuria during follow-up (mean, 36.0 ± 11.7 months; range, 18 to 76 months). The control group consisted of 152 age- and sex-matched subjects who did not develop microalbuminuria. Baseline plasma homocysteine concentrations were measured in stored samples.

Results

Baseline plasma homocysteine concentrations and mean HbA1C levels during follow-up were significantly higher in patients who developed microalbuminuria than in those who remained normoalbuminuric. Multivariate logistic regression analysis showed that baseline plasma homocysteine level and mean HbA1C were independent predictors of microalbuminuria in type 2 diabetes.

Conclusion

Hyperhomocysteinemia was associated with increased risk of microalbuminuria in patients with type 2 diabetes supporting the concept that hyperhomocysteinemia has an etiologic role in the pathogenesis of diabetic nephropathy.

AbstractAbstract PDF
BACKGROUND
Chronic complications in type 2 diabetic patients have microvascular and macrovascular components. Previous studies have shown that incidence of macrovascular complications correlates with the serum homocysteine levels, but the relationship is unclear. In addition, the connection between the microvascular complications and the serum homocysteine levels is still obscure and controversial. In this study, the relationship between the serum homocysteine levels and microvascular and macrovascular complications were evaluated in type 2 diabetic patients. METHODS: In 58 type 2 diabetic patients, the serum homocysteine levels, folic acid levels, Vit B12 levels, PAI-1 levels, the standard risk factors for macrovascular complications, the fasting serum glucose levels, the HbA1C levels, and the fasting insulin and C-peptide concentrations, the renal function tests, and the carotid intima-media thickness were measured and the relationship between them and the serum homocysteine level was analyzed according to the presence and absence of macrovascular and microvascular complications. RESULTS: 1) In type 2 diabetic patients, the mean serum homocysteine level was 9.9+/-.2 mol/L. The serum homocysteine level showed no relationship with the clinical and biochemical variables including the risk factors for atherosclerosis except the serum creatinine and creatinine clearance. 2) The maximum, minimum, and mean of the intima- media thickness of right carotid artery were 4.00+/-.20, 0.50+/-.04, 1.04+/-.62 mm, of left carotid artery were 3.54+/-.00, 0.31+/-.02, 1.03+/-.55 mm, and means were 3.77+/-.10, 0.44+/-.03, 1.03+/-.54 mm, and correlated with the serum homocysteine leve l (p=0.03), but only the serum LDL cholesterol level independently correlated with the intima-media thickness (p=0.04). 3) The serum homocysteine level (p=0.01) and intima-media thickness (p<0.01) was significantly higher in type 2 diabetic patients with macrovascular complications than without it. 4) The serum homocysteine level did not correlate with the incidence microvascular complications, but the intima-media thickness did correlate with diabetic nephropathy (p=0.03). CONCLUSIONS: The serum homocysteine level did not correlated with the incidence of diabetic microvascular complications. However, there was a small correlation with the risk factors of macrovascular complications. The intima- media thickness correlated with the incidence of macrovascular complications, and the relationship with diabetic nephropathy requires further study.

AbstractAbstract PDF
BACKGROUND
Hyperhomocysteinemia is an inde-pendent risk factor for cardiovascular disease. Recently, a mutation (677CT) was identified in the methylenetetrahydrofolate reductase (MTHFR) gene, leading to the substitution of valine (V) for alanine (A). This mutation causes a reduced folate-dependent enzyme activity which leads to increased homocysteine. In this study, we examined the association between the V allele of the methylenetetrahydrofolate reductase gene and macroangiopathy in Korean patients with type 2 diabetes mellitus. METHODS: In 54 type 2 diabetic patients with macroangiopathy and 198 normal subjects, the MTHFR genotypes were analyzed by polymerase chain reaction (PCR), followed by Hinfl digestion. To confirm the detection of the MTHFR polymorphism by the PCR-restriction fragment length polymorphism (RFLP) analysis, DNA Sequencing was performed on the PCR products. RESULT: The allele frequency of the V mutation was slightly higher in the patients than in the normal subjects, but that was statistically not significant. The crude ORs and 95% CIs for the allele frequency of the V mutation were 1.16 (0.76~1.79). Genotype frequencies were 35.9% for AA, 48.4% for AV, and 15.7% for VV in the normal subjects. And they were 31.5% for AA, 50.0 % for AU, and 18.5 % for VV in the patients. The crude ORs and 95% CIs for the VV genotype were 1.22 (0.56~2.67). In multiple regressian model, the VV genotype was not associated with diabetic macroangiopathy. CONCLUSION: Although, the frequencies of VV genotype in Korean normals (=16%) are higher than those of other thical populations (=12%), this mutation is not associated with macroangiopathy in type 2 diabetic patients. But, our sample size was too small and larger cohort studies will be needed to confirm the effect of MTHFR polymorphism on the development of macroangiopathy in diabetic patients.
