Clinical and laboratory characteristics COVID-19

ABSTRACT

The problem of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains highly relevant. Objective. To analyze clinical and laboratory characteristics of patients with moderate COVID-19. Materials and methods. This retrospective study included 132 patients with moderate COVID-19 treated in the Republican Immunological Center of the Republic of Dagestan between July and December 2020. The sample included 69 males and 63 females with a mean age of 52.4 ± 5.9 years. Results. The most common clinical manifestations included fever, fatigue, dry cough, and headache. Many participants had increased erythrocyte sedimentation rate (ESR);some patients had leukopenia, lymphopenia, and thrombocytopenia. Biochemical testing demonstrated mild alterations in the levels of C-reactive protein (CRP), ferritin, glucose, activity of liver enzymes (alanine aminotransferase, as-partate aminotransferase), fibrinogen, and D-dimer. These alterations were primarily observed in COVID-19 patients with CT-2 changes in their lung tissue. One-third of participant had lesions in lungs upon discharge. ECG changes (rhythm and conduction abnormalities) were detected in 15.9% of patients with concomitant cardiovascular diseases. Conclusion. COVID-19 patients with persistent clinical, laboratory, or radiological changes upon their discharge from hospital, as well patients with changes on ECG, require careful follow-up to assess their long-term outcomes. © 2021, Dynasty Publishing House.
