    Frequency of Evidence-Based Screening for Retinopathy in Type 1 Diabetes.
    • Authors:
    N Engl J Med 2017 04;376(16):1507-1516
    Background In patients who have had type 1 diabetes for 5 years, current recommendations regarding screening for diabetic retinopathy include annual dilated retinal examinations to detect proliferative retinopathy or clinically significant macular edema, both of which require timely intervention to preserve vision. During 30 years of the Diabetes Control and Complications Trial (DCCT) and its longitudinal follow-up Epidemiology of Diabetes Interventions and Complications (EDIC) study, retinal photography was performed at intervals of 6 months to 4 years. Methods We used retinal photographs from the DCCT/EDIC study to develop a rational screening frequency for retinopathy. Read More

    Evaluation of vitreous levels of advanced glycation end products and angiogenic factors as biomarkers for severity of diabetic retinopathy.
    Int Ophthalmol 2017 Mar 15. Epub 2017 Mar 15.
    Department of Medicine, Diabetes Center, Tokyo Women's Medical University School of Medicine, Tokyo, Japan.
    Background/aims: Glyceraldehyde-derived advanced glycation end products (glycer-AGE; also called Toxic-AGE [TAGE]) play a crucial role in the pathogenesis of diabetic angiopathy. However, the relationships between vitreous glycer-AGE levels and diabetic retinopathy (DR) severity, and between glycer-AGE levels and the levels of other angiogenic factors remain unknown. We investigated the correlation between levels of vitreous biomarkers, including glycer-AGE and angiogenic factors (vascular endothelial growth factor [VEGF], interleukin [IL]-8, leptin, placental growth factor [PlGF], endoglin, and fibroblast growth factor [FGF]-2) in patients with DR, using three DR staging groups.

    Background Laser therapy is an important treatment option in retinal diseases, especially in cases of vascular involvement. Most approaches are based on coagulation of retinal structures. As there is increasing use of agents targetting vascular endothelial growth factor in the treatment of macular diseases, indications for the use of laser treatment need to be reviewed carefully, especially with respect to their significance in first line therapy.

    The A445C Variant in Apelin Receptor and Diabetic Retinopathy in Tunisian Patients.
    Clin Lab 2017 Feb;63(2):379-383
    Background: Apelin and apelin receptor (APLN/APLNR) are involved in the retinal neovascularization of diabetic retinopathy (DR).

    Methods: This study investigated the impact of the APLNR A445C variant on the risk of DR in a sample of the Tunisian population (100 patients with DR and 105 healthy controls) using PCR-RFLP.

    Results: The genotype frequencies of the APLNR A445C variant were not significantly different between the patient and control groups. Read More

    Circulating monocytes and B-lymphocytes in neovascular age-related macular degeneration.
    Clin Ophthalmol 2017 17;11:179-184. Epub 2017 Jan 17.
    Clinical Eye Research Unit, Zealand University Hospital, Roskilde; Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.
    Background: Individuals with neovascular age-related macular degeneration (AMD) have altered number and distribution of retinal macrophages and show changes in circulating antibodies. We wanted to investigate the corresponding precursors, with subpopulations. We therefore measured monocyte and B-lymphocyte populations in individuals with neovascular AMD. Read More

    Design: Prospective observational study. Read More

    [The protective effect of human umbilical cord mesenchymal stem cells-induced neural stem cells in the vitreous on the blood-retinal barrier in diabetic rats].
    Zhonghua Yan Ke Za Zhi 2017 Jan;53(1):53-58
    Tianjin Eye Hospital, Tianjin Key Laboratory of Ophthalmology and Vision Science, Tianjin Institute of Ophthalmology, Clinical College of Ophthalmology of Tianjin Medical University, Tianjin 300020, China.
    Objective: To investigate the effect of intravitreal injection of neural stem cells (NSC) induced from human umbilical cord mesenchymal stem cells, and to provide a theoretical basis for the clinical treatment of blood-retinal barrier damage due to diabetic retinopathy (DR). Methods: Experimental study. Sixty male Sprague-Dawley rats were randomly divided into control group, DR group and NSC group. Read More

    Membranous nephropathy occurring with type 2 diabetes mellitus
.
    Clin Nephrol 2017 Mar;87 (2017)(3):140-146
    Background: The incidence of type 2 diabetes mellitus (T2DM) is increasing, and membranous nephropathy (MN) occurs frequently with T2DM. We investigated the clinicopathological features and outcomes of patients with T2DM and MN.

    Methods: A total of 137 patients with biopsy-proven MN and T2DM were enrolled in this retrospective study. Read More

    Role of oxidative stress in epigenetic modification of MMP-9 promoter in the development of diabetic retinopathy.
    Graefes Arch Clin Exp Ophthalmol 2017 May 25;255(5):955-962. Epub 2017 Jan 25.
    Kresge Eye Institute, Wayne State University, Detroit, MI, 48201, USA.
    Background: In the pathogenesis of diabetic retinopathy, damaged retinal mitochondria accelerate apoptosis of retinal capillary cells, and regulation of oxidative stress by manipulating mitochondrial superoxide dismutase (SOD2) protects mitochondrial homeostasis and prevents the development of diabetic retinopathy. Diabetes also activates matrix metalloproteinase-9 (MMP-9), and activated MMP-9 damages retinal mitochondria. Recent studies have shown a dynamic DNA methylation process playing an important role in regulation of retinal MMP-9 transcription in diabetes; the aim of this study is to investigate the role of oxidative stress in MMP-9 transcription.

    Progranulin, a new adipokine at the crossroads of metabolic syndrome, diabetes, dyslipidemia and hypertension.
    Curr Pharm Des 2017 Jan 24. Epub 2017 Jan 24.
    Department of Pathophysiology, Medical University, Lublin, Poland.
    Background: Progranulin is a multifunctional regulatory protein with growth-promoting, neuroprotective and antiinflammatory activities. Recent studies indicate that progranulin is one of the adipose tissue hormones (adipokines). Progranulin expression in visceral adipose tissue and circulating progranulin concentration are increased in obesity and hyperprogranulinemia is involved in the pathogenesis of obesity-associated insulin resistance.
