Introduction: Diabetic retinopathy (DR) is a microvascular disorder of the retina caused by hyperglycemia in the blood vessels and is the most common complication in the eye due to diabetes mellitus (DM). The aim of this study was to determine the VEGF -460C/T gene polymorphism as a risk factor for diabetic retinopathy in T2DM patients in Bali. Materials and Methods: The design of this study was case-control with 27 cases of type 2 DM with DR and 29 cases without RD as controls. The VEGF-460C/T polymorphism in DNA was detected using PCR and DNA sequencing at rs833061 to see the distribution of the C/T allele variation. Data were analyzed using chi-square test. Results: Based on bivariate analysis comparing homozygous TT genotype variants, heterozygous CT and wild-type CC in this study, no significant relationship was found with the incidence of DR (p=0.742). Conclusion: Polymorphism of the VEGF-460C/T gene (rs833061) can be concluded as an irrelevant factor with the risk of developing DR in type 2 diabetes mellitus patients in Bali. Keywords: VEGF -460C/T, Diabetes Mellitus, Polymorphism, Risk Factors.

The Relationship

AIM: To estimate the level of serum lipoprotein (a) [Lp (a)] in type 2 diabetes mellitus patients and to determine the relationship between Lp(a) in type 2 diabetes mellitus patients and micro-vascular complications. METHODS: A cross sectional study was performed that enrolled 144 subjects with type 2 diabetes mellitus above the age of 25 years attending outpatient Department of Medicine, Madhubani Medical College & Hospital, Madhubani, Bihar. Lp(a) levels were measured quantitatively in venous samples using Turbidimetric Immunoassay in all subjects. Each patient was evaluated for micro vascular complications, namely diabetic retinopathy, nephropathy and neuropathy. The relationship between Lp(a) levels and the micro vascular complications was assessed by univariate analysis. RESULTS: Mean age of cases was 53.93 ± 10.74 years with a male to female ratio of 1.3:1. Mean duration of diabetes was 9.53 ± 7.3 years. Abnormal Lp(a) levels (≥ 30 mg/dL) were observed in 38 (26.4%) diabetic subjects. Seventy-eight (54.16%) cases had diabetic nephropathy and signicantly higher Lp(a) levels were found among these cases [Median 28.2 mg/dL(Interquartile range; IQR 24.4-33.5) vs 19.3 mg/dL(IQR 14.7- 23.5); P< 0.05]. Retinopathy was present among 66 (45.13%) cases and peripheral neuropathy was detected among 54 (37.5%) cases. However, Lp(a) levels were not signicantly different among those with or without retinopathy and neuropathy. Positive correlation was found between higher Lp(a) levels and duration of diabetes (r = 0.165, P< 0.05) but not with HbA1c values (r = – 0.083). CONCLUSION: Abnormal Lp(a) levels were found among 26.4% of diabetic subjects. Patients with diabetic nephropathy had higher Lp(a) levels. No association was found between Lp(a) levels and diabetic retinopathy or neuropathy. Longer duration of diabetes correlated with higher Lp(a) levels.

ABSTRACT Objective: To assess the association of vitamin D (VD) and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). Method: Literature search was conducted for studies assessing the association of VD and DR. Total 9 studies have a sum total of 1741 patients were included for final analysis. Results: The concentration of VD in controls ranged from 17.5±3.6 to 31.9±12.9 ng/ml, while for T2DM patients without retinopathy it ranged from 11.94±4.21 to 23.10±6.12 ng/ml. T2DM patients with retinopathy had the lowest concentration, ranging from 10.02±5.61 to 19.25±7.86 ng/ml. Ahigher percentage of T2DM patients without (50.7% to 68.80%) and with (31.2% to 79.63%) retinopathy had VD deficiency (VDD). Discussion: An inverse association between VD levels and DR was observed. The concentration of VD decreases as the stage of DR advances. VD seems to be an easily modifiable risk factor for DR. Thus, VD supplementation should be encouraged in population at higher risk for diabetic complications.

Abstract Introduction:Diabetic retinopathy (DR), as a serious and specific neurovascular complication of DM, remains the leading cause of vision loss and preventable blindness in adults aged 20–74 years. Several studies have indicated that chronic inflammation plays an important role in DR. Emerging evidence suggests that the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) are novel potential markers of inflammatory responses. However, only a few articles have evaluated the association between these factors and DR.Patients and Methods: The study included 133 patients diagnosed with type 2 diabetes mellitus (T2DM). Retinopathy was graded using the International Clinical Diabetic Retinopathy Disease Severity Scale.Results:The mean NLR, PLR and MLR were significantly higher in patients with DR than in patients without DR (p < 0.001, p = 0.002, and p = 0.003, respectively). In the post hoc analysis, the PDR group had the highest NLR and MLR values among the three groups. Multiple logistic regression showed that the PLR was an independent risk factor for DR (odds ratio [OR]: 1.022, 95% confidence interval [CI]: 1.005–1.040 p = 0.013). Based on the receiver operating characteristic (ROC) curve, the cutoff value of PLR as an indicator for DR diagnosis was projected to be 78.70 and yielded a sensitivity and specificity of 80.7% and 48.9%, respectively, with an area under the curve of 0.669 (95% CI: 0.572–0.765, P = 0.002).Conclusions:Our results suggest that PLR may be an independent risk factor for evaluating DR in patients with type 2 diabetes.
