Abstract
SARS-CoV-2 (Severe Acute Respiratory Syndrome-related CoronaVirus 2) infection is characterized by multi-comorbidity, which increases the severity of the disease. The aim of the study was to identify the relationship between the length of stay in the hospital and the comorbidity and the severity of lung damage. Methods. 72 patients with COVID-19 (COronaVIrus Disease 2019) infection were studied, including 33 women and 39 men who were treated in the city hospitals. The average age was 67.4 ± 12.02 years. The SARS-CoV-2 RNA virus was identified by PCR in 46 (63.8%) patients. Results. The most common comorbidities in chronic obstructive pulmonary disease (COPD) patients with COVID-19 included arterial hypertension (in 32%), coronary artery disease (17%), and type 2 diabetes (10%). The majority of patients (48.7%) had the CT II stage. The total proportion of patients with an advanced damage (corresponding to CT III - IV) was 36.2%. Mean hospitalization length was 13.8 ± 7.9 days. Conclusion. COPD patients with COVID-19 infection included a significant percentage of patients with arterial hypertension, which required additional treatment.
