Endothelial Growth Factor

Vascular endothelial growth factor (VEGF) is an important regulator of angiogenesis and has been investigated as a candidate gene in a number of conditions, including diabetes and its microvascular complications (e.g., retinopathy and nephropathy). Several VEGF-related polymorphisms have been shown to contribute to nearly half of the variability in circulating VEGF levels in healthy individuals. Our aim was to assess the association between VEGF-related rs10738760 and rs6921438 polymorphisms and proliferative diabetic retinopathy (PDR) in Slovenian patients with type 2 diabetes mellitus (T2DM). We also investigated the effect of these polymorphisms on VEGF receptor 2 (VEGFR-2) expression in fibrovascular membranes (FVMs) from patients with PDR. This case-control study enrolled 505 unrelated patients with T2DM: 143 diabetic patients with PDR as a study group, and 362 patients with T2DM of >10 years duration and with no clinical signs of PDR as a control group. Patient clinical and laboratory data were obtained from their medical records. rs10738760 and rs6921438 polymorphisms were genotyped using TaqMan SNP Genotyping assay. VEGFR-2 expression was assessed by immunohistochemistry in 20 FVMs from patients with PDR, and numerical areal density of VEGFR-2-positive cells was calculated. The occurrence of PDR was 1.7 times higher in diabetic patients carrying GA genotype of rs6921438 compared to patients with GG genotype, with a borderline statistical significance (OR = 1.7, 95% CI = 1.00 – 2.86, p = 0.05). In addition, A allele of rs6921438 was associated with increased VEGFR-2 expression in FVMs from PDR patients. However, we observed no association between AA genotype of rs6921438 nor between rs10738760 variants and PDR, indicating that the two polymorphisms are not genetic risk factors for PDR.

Background and Objective: Nowadays, diabetes is one of the main causes of blindness in the world. Identification and differentiation of risk factors for diabetic retinopathy depending on the type of diabetes gives us the opportunity to fight and prevent this complication. Aim of the research: To assess differences in the risk factors for diabetic retinopathy in type 1 and type 2 diabetes mellitus patients in Warmia and Mazury Region, Poland. Materials and Methods: Risk factors for diabetic retinopathy (DR) were assessed on the basis of an original questionnaire, which included: personal data, clinical history of diabetes and eye disease. Elements of clinical examination: blood pressure, BMI, waist circumference. Indicators of diabetes metabolic control: mean glycemia, glycated hemoglobin (HbA1c), total cholesterol and triglycerides, creatinine, glomerular filtration rate (GFR), albumin–creatinine ratio in urine. Results: The study group included 315 (26%) patients with DM1 and 894 (74%) patients with DM2. Risk factors were estimated on the basis of logistic regression and verified with Student’s t-test. Statistically significant dependencies were found in both groups between the occurrence of diabetic retinopathy and diabetes duration, HbA1c, triglyceride concentrations, indicators of kidney function and cigarette smoking status. In the DM2 group, the development of DR was significantly influenced by the implemented models of diabetic treatment. Conclusions: In the whole study group, the risk of DR was associated with the duration of diabetes, HbA1c, triglyceride concentrations and smoking. In DM1 patients, the risk of DR was associated with diabetic kidney disease in the G1A1/A2 stage of chronic kidney disease, and in DM2 patients with the G2 stage of chronic kidney disease. An important risk factor for DR in DM2 patients was associated with late introduction of insulin therapy.

Abstract Purpose To analyze the clinical features and related risk factors in diabetic retinopathy (DR) and subclinical atherosclerosis, the micro- and macro-vascular diseases in newly diagnosed type 2 diabetes mellitus (T2DM). Methods A retrospective study of 435 cases of inpatients with newly diagnosed T2DM from 2013–2017, and compare the 2 types of T2DM related vascular complications. Results The macro- and microvascular complications are not rare at this stage. Subclinical atherosclerosis was found in 251 subjects (57.7%), which was higher than that of DR (13.1%). In addition, some cases of subclinical atherosclerosis co-existed with DR, suggesting that DR was related with subclinical atherosclerosis (r=0.098, P=0.041). Older age showed a significant association with both subclinical atherosclerosis and DR. Single factor analysis indicated that dyslipidemia was the common risk factor in DR and subclinical atherosclerosis. Conclusions It should be paid attention to the screening of both DR and subclinical atherosclerosis in each age group of newly diagnosed T2DM. Except for the control of blood glucose, the control of the dyslipidemia is important in the prevention and treatment of the micro- and macro-vascular diseases.

The Impact

IntroductionThis study was aimed at analyzing, modeling, and comparing the risk factors of diabetic retinopathy (DR) among type 2 diabetes mellitus (DM) patients with and without metabolic syndrome (MS).Material and methodsA cross-sectional study from July 2017 to July 2019 was performed by tracing type 2 DM patients who received treatment at an out-patient clinic and a mydriatic examination by an ophthalmologist in a single institute in south Taiwan. A total of 802 patients without DR were recruited and divided into two groups based on whether they had MS for this study. We analyzed the impact of DR based on the potential and related factors of these two groups.ResultsThe sample consisted of 802 patients; 282 patients did not have MS, and 520 did. A comparison of the risk factors of DR among the patients with and without MS revealed that the level of glycated hemoglobin (HbA1c) was a co-risk factor of DR. However, female sex, betel quid chewing, family history of DM, and higher total cholesterol were found to be risk factors of DR among the patients who had MS. Betel quid chewing, especially, could exacerbate the disease condition of DM and elevate the risk of DR.ConclusionsOf those risk factors, betel quid chewing may be the main reason for DM deterioration and raised risk of DR. Hence, we recommend that the chewing of betel quid should be avoided to prevent DR.
