Enhanced Oxidative Stress and Other Potential Biomarkers for Retinopathy in Type 2 Diabetics: Beneficial Effects of the Nutraceutic Supplements
We have studied the global risk of retinopathy in a Mediterranean population of type 2 diabetes mellitus (T2DM) patients, according to clinical, biochemical, and lifestyle biomarkers. The effects of the oral supplementation containing antioxidants/omega 3 fatty acids (A/ω3) were also evaluated. Suitable participants were distributed into two main groups: (1) T2DMG (with retinopathy (+DR) or without retinopathy (−DR)) and (2) controls (CG). Participants were randomly assigned (+A/ω3) or not (−A/ω3) to the oral supplementation with a daily pill of Nutrof Omega (R) for 18 months. Data collected including demographics, anthropometrics, characteristics/lifestyle, ophthalmic examination (best cor…
Analysis of gene expression in relation to concentrations of antioxidants, vitamin B12, folate and homocysteine in patients with type 2 diabetes mellitus
La Diabetes Mellitus (DM) constituye una de las causas más importantes de pérdida de visión y de la calidad de vida relacionada con la visión en todo el mundo, puesto que presenta un gran número de complicaciones en su desarrollo, siendo una de las más importantes la retinopatía diabética (RD). En la actualidad la DM se considera una pandemia, puesto que su prevalencia no deja de aumentar. La RD es una patología ocular en auge, causa de ceguera en todo el mundo con una prevalencia del 34,6%. Las personas con RD a menudo no se dan cuenta de los cambios en su visión durante las primeras etapas de la enfermedad pero, a medida que avanza, causa una pérdida importante de visión e incluso ceguera…
Identificación de nuevos genes candidatos para la retinopatía en diabéticos tipo 2. Estudio Valencia sobre Retinopatía Diabética (EVRD). Informe n.° 3
Resumen Objetivo Identificar genes implicados en los mecanismos patogenicos de la retinopatia diabetica no proliferante, como estres oxidativo, alteracion de la matriz extracelular y/o apoptosis, para valorar el riesgo de desarrollo de la misma en una poblacion de diabeticos tipo 2 (DM2). Material y metodos Estudio de casos y controles en 81 participantes del Estudio Valencia sobre Retinopatia Diabetica (EVRD), de ambos sexos y con edades comprendidas entre los 25 y 85 anos, clasificados en: 1) grupo DM2 (n = 49), con RD (+RD; n = 14) y sin RD (−RD; n = 35), y 2) grupo control (GC; n = 32). Se realizo entrevista personal, examen oftalmologico estandarizado y extraccion de sangre que se proc…
Identification of new candidate genes for retinopathy in type 2 diabetics. Valencia Study on Diabetic Retinopathy (VSDR). Report number 3
Abstract Objective To identify genes involved in the pathogenic mechanisms of non-proliferative diabetic retinopathy (NPDR), among which include oxidative stress, extracellular matrix changes, and/or apoptosis, in order to evaluate the risk of developing this retinal disease in a type 2 diabetic (DM2) population. Material and methods A case–control study was carried out on 81 participants from the Valencia Study on Diabetic Retinopathy (VSDR) of both genders, with ages 25–85 years. They were classified into: (i) DM2 group (n = 49), with DR (+DR; n = 14) and without DR (−DR; n = 35), and (ii) control group (GC; n = 32). The protocols included a personal interview, standardized ophthalmologic…
Strategies to Reduce Oxidative Stress in Glaucoma Patients
Background Primary open-angle glaucoma (POAG) is a multifactorial pathology involving a variety of pathogenic mechanisms, including oxidative/nitrosative stress. This latter is the consequence of the imbalance between excessive formation and insufficient protection against reactive oxygen/nitrogen species. Objective Our main goal is to gather molecular information to better managing pathologic variants that may determine the individual susceptibility to oxidative/nitrosative stress (OS/NS) and POAG. Method An extensive search of the scientific literature was conducted using PUBMED, the Web of Science, the Cochrane Library, and other references on the topic of POAG and OS/NS from human and a…
