Diabetes and COVID-19: analysis of the clinical outcomes according to the data of the russian diabetes registry

BACKGROUND: Data on the national level and worldwide show a higher rate of mortality in patients with diabetes mellitus (DM) due to COVID-19, which determines the high relevance of risk factor analysis for outcomes in DM patients to substantiate the strategy for this category of patients. AIM: To assess the effect of clinical and demographic parameters (age, gender, body mass index (BMI), glycemic control (HbA1c), and antidiabetic and antihypertensive drugs, including ACE inhibitors and ARBs) on clinical outcomes (recovery or death) in patients with type 2 DM. MATERIALS AND METHODS: A retrospective analysis of the Russian Register of Diabetes database was performed, including patients with type 2 DM (n=309) who suffered pneumonia/COVID-19 in the period from 01.02.2020 to 27.04.2020 and the indicated outcome of the disease (recovery or death) RESULTS: The percentage of lethality was determined to be 15.2% (47 of 309 people). The degree of lethality was found to be significantly higher in males (OR=2.08; 95% CI 1.1–3.9; p=0.022) and in patients on insulin therapy (OR=2.67; 95% CI; 1.42–5.02; p=0.002), while it was significantly lower in patients with an ag
