Clinical features, laboratory characteristics, and outcomes of patients hospitalized with coronavirus disease 2019 (COVID-19): Early report from the United States.

Background Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV2), is an ongoing pandemic that has already affected millions of patients worldwide, and is associated with significant morbidity and mortality burden. Although the clinical and laboratory characteristics of this illness have been reported in patients from China and Europe, data are scant in the United States. Methods We extracted data regarding all patients hospitalized at our hospital with COVID-19 infection between March 1 and April 4, 2020. Presenting signs and symptoms, laboratory and imaging findings, treatment, and complications were recorded from electronic medical records (EMRs). The primary composite endpoint was admission to intensive care unit (ICU), shock, or death. Results We had a total of 43 patients tested for COVID-19 at the emergency room (ER) or during hospitalization, 16 (37%) of whom were admitted with COVID-19 infection. The mean age was 65.5 years and 75% were males. The most common presenting symptoms were fever (94%), cough (88%), and dyspnea (81%). A loss of smell and taste sensations were reported by three (19%) patients. Low oxygen saturation was present in 38% of patients, whilst 31% were hypotensive on admission. Hyponatremia (50%), elevated C-reactive protein (CRP; 100%), and lactate dehydrogenase (LDH; 80%) were common. Acute renal failure, myocardial injury, and elevation in aminotransferases occurred in 69%, 19%, and 38% patients, respectively. The primary composite endpoint occurred in 50% of patients. A total of three patients died; all were aged 70 years or older. Conclusions Laboratory abnormalities and acute renal failure were common in hospitalized patients with SARS-CoV2 infection in our center. Admission to ICU and mechanical ventilation were common.
