Glycated hemoglobin level dynamics in COVID-19 survivors: 12 months follow-up study after discharge from hospital.

Introduction: One of the stages of reproduction of SARS-CoV-2 is the S-protein glycosylation to facilitate penetration into target cells. It has been suggested that SARS-CoV-2 is able to enter erythrocytes, interact with heme and porphyrin, which could influence HbA1c levels. Assessment of HbA1c levels in individuals with acute COVID-19 and after recovery may show clinical relevance of this hypothesis.

Association of polymorphic markers of genes , and with type 2 diabetes mellitus in the Russian population.

Background: The association of type 2 diabetes mellitus (T2DM) with the and genes in the Russian population has not been well studied. In this study, we analysed the population frequencies of polymorphic markers of these genes.

Methods: The study included 862 patients with T2DM and 443 control subjects of Russian origin.
