Clinical characteristics of liver, kidney and coagulation injury in elderly patients with novel coronavirus pneumonia (COVID-19) / 上海预防医学

ABSTRACT

Objective To evaluate the clinical features and clinical outcome of liver, kidney and coagulation injury in patients with novel coronavirus pneumonia (COVID-19), especially in those elderly COVID-19 patients. Methods Clinical data of 72 COVID-19 patients admitted to the Shanghai Public Health Clinical Center from January 20, 2020 to April 20, 2020 was collected, including demographic data, clinical symptoms, laboratory testing results, underlying comorbidities, discharge and death, and then conducted the analysis stratified by clinical severity and age. Results Of the 72 COVID-19 patients, 27 were critically ill and 45 were mild.There were 31 elderly patients (≥60 years old) and 41 young patients (< 60 years old).Fever (83.3%), cough (36.1%) and fatigue (23.6%) were the most common clinical symptoms.The median age of the patients was 56.1 years (15-80 years); the mean age of mild and critically ill patients were 47.4 years and 64.6 years, respectively.The proportion of critically ill cases in the elderly group and the young group was 67.7% (21/31) and 14.6% (6/41), respectively.Organ injury in elderly patients included significantly increased aspartate aminotransferase, creatinine D-dimer, and FDP) (P < 0.05).Of the patients, the length of hospital stay of the elderly patients was significantly longer (P < 0.001), and the mortality increased significantly (P < 0.05). Conclusion Elderly COVID-19 patients have severe liver, kidney and coagulation injury, which may induce longer duration of hospital stay and increased mortality.Therefore, elderly COVID-19 patients may have worse clinical outcome.
