The purpose of the study is to estimate diagnostic value of optical coherence tomography angiography (OCT-angiography) parameters in patients with diabetic retinopathy. Material and Methods. The investigation included 102 patients with diabetes mellitustype II and different stages of diabetic retinopathy and 48 clinically healthy people. Apart from routine ophthalmological examination all patients underwent optical coherence tomography of the macular area. To estimate diagnostic value of OCT-angiography, we performed ROC-analysis of the most informative parameters. Results. The most significant differences in OCT-angiography data between patients with different stages diabetic retinopathy (groups I and II) and healthy people (control group) were noted for general vascular density in all sectors (Whole image) and parafoveal zone (Parafovea) of the superficial vascular plexus. The ROC-analysis showed high sensitivity and specificity of the same zones for control group and group I, as well as for groups I and II. Conclusion. The capillary network density for Parafovea in patients with diabetes mellitus is less than 52% and for Whole image it is less than 48.5%, which indicates the presence of non-proliferative and pre-proliferative retinopathy, while the reduction of Parafovea parameters lower than 43.6% and Whole image lower than 47.5% indicates proliferative diabetic retinopathy.

The aim of the article: to study the medical and social aspects of diabetes mellitus and diabetic retinopathy at the regional level. Material and Methods. The prevalence, structure and dynamics of diabetes and diabetic retinopathy (DR) were analyzed among the population of the Tambov region for a seven-year period from 2010 to 2016 based on statistical compendiums on the main indicators of health facilities and the health of the population of the Tambov region (2010-2016) Russian statistical yearbooks (2010-2016), data from the regional State register of patients with diabetes. Results. In 2016 in the Tambov region, the prevalence of DR in type 1 diabetes is 53.2%, with type 2 diabetes 31.2%, significantly higher than all-Russian indicators, which were registered at 27.2% in patients with type 1 diabetes and 13.0% of patients with type 2 diabetes. Conclusion. The results of the comparative analysis of the level and structure of diabetes and DR indicate a negative trend among the population of the Tambov region, which dictates the need to develop effective and inexpensive methods for preventing the development and progression of DRs and making management decisions based on them.

Erythropoietin in patients with type 1 diabetes (review)

Year: 2012, volume 8 Issue: №1 Pages: 159-163
Heading: Endocrinology Article type: Review

The article analyzes the literature on the issue of regulation of erythropoietin in patients with type 1 diabetes. The connection between the secretion of erythropoietin disturbance with the development and progression of diabetes complications has been observed. Various pleiotropic effects of erythropoietin have been considered
