CLINICAL CASE OF SARS-COV-2 LONG INFECTION

Abstract

Вackground. Coronavirus (COVID-19) infection caused by SARS-CoV-2 virus is associated with a wide spectrum of clinical respiratory syndromes ranging from mild upper respiratory tract symptoms to progressive viral pneumonia and systemic multinflammatory syndrome, as well as endothelial dysfunction and thrombotic complications. Despite the decline of the pandemic, the problem of the prolonged course of SARS-CoV-2 remains relevant. Aim of the study. To present a clinical case of Sars-Cov-2 long infection with development of severe lung and myocardial damage with negative results of PCR-analysis of pharyngeal and nasal swabs. Characteristics of patients and methods of research. A clinical case demonstrating a variant of prolonged course of coronavirus infection accompanied by the development of pneumonitis and myocarditis is presented in this work. Blood smear morphometry, monocyte analysis (flow cytometry), T lymphocyte analysis were performed in addition to standard methods of examination. Results and Conclusion. The presented clinical case demonstrates a variant of prolonged course of coronavirus infection, in which SARS-CoV-2 virus was encapsulated in the lungs and avoided the formation of a specific immune response. Severe lung and myocardial damage with negative results of PCR analysis of pharyngeal and nasal swabs was observed. Pulse therapy with corticosteroids resulted in regression of the disease.
