RESUMEN
The aim of our work was to investigate the peculiarities of hematological indicators in patients with COVID-19 depending on the variant of SARS-CoV-2. A retrospective study of the electronic medical records of 19 patients with the delta variant (7 patients had comorbidity with type 2 diabetes (T2D);12 patients without T2D - control group) and 46 patients with the omicron variant (26 patients had comorbidity with T2D;20 patients without T2D - control group). No statistically significant differences were found in gender, the number of leukocytes, lymphocytes, and granulocytes in peripheral blood, C-reactive protein, and D-dimer. The results also showed a significant difference in procalcitonin level and monocyte count in patients with delta variant and T2D. A predictive model was developed using binary logistic regression to determine the SARS-CoV-2 variant based on hematological parameters (sensitivity - 76.5%, specificity - 84.8%). Thus, the peculiarities of hematological indicators of patients with T2D depending on the variant of SARS-CoV-2 (delta or omicron) were established. © P. Petakh, K. Loshak, A. Kamyshnyi.
