Clinical characteristics of SARS-CoV-2 disease (COVID-19) in middle-aged patients
Coronavirus disease 2019 (COVID-19) meant an unprecedented global crisis, which involved the reorganization of health systems and the rationalization of available diagnostic and therapeutic resources. The objective of this observational and retrospective study was to analyze the clinical characteristics and evolution of patients admitted to general ward, intensive care unit and emergency department of a high complexity hospital in Buenos Aires city, during the first seven months of viral circulation. A total of 1005 patients with laboratory-confirmed COVID-19 were included. The median age was 45 years, and 73.7% were men. Half of the patients had at least one comorbidity. Among the laboratory findings, the median of total leukocytes was 6300 cells/mm3 and that of lymphocytes 818 cells/mm3; 82.3% of the patients presented alterations in the chest tomography, and the most frequently observed radiological pattern was ground-glass opacity (33%); 82.4% of them received empirical antibiotic therapy directed to the respiratory focus and, in addition, 18.7% were treated with dexamethasone. Regarding severity, 14.7% of the patients presented uncomplicated disease, 55.2% mild pneumonia, 20.8% moderate pneumonia, and 9.2% severe pneumonia. Likewise, 8.7% of them were transferred to intensive care. In-hospital mortality was 2.3%, and 20.5% among critically ill patients. A statistically significant association was found between mortality and age, with an age difference of 9.6 years, being greater among the deceased (p = 0.0004; 95% CI 4-14). However, there was no association between the presence of comorbidities and sex vs. mortality and severity of the disease.
