COVID-19 in Peritoneal Dialysis Patients

Continuous variables were described as median and interquartile range or mean and SD, and differences were assessed using analysis of t test or Mann–Whitney U test. Categorical variables were expressed as number (percentage), and differences between groups were assessed using the Fisher exact test. ARDS was defined according to the Berlin definition. Acute cardiac injury was diagnosed if the serum levels of cardiac biomarkers (e.g., troponin I) were above the 99th percentile upper reference limit or new abnormalities were shown in electrocardiography and echocardiography. Acute hepatic injury was defined as an elevation in AST or ALT of >15 times the upper limit of normal. CAPD, continuous ambulatory peritoneal dialysis; APD, automated peritoneal dialysis; DAPD, daytime ambulatory peritoneal dialysis; ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin receptor blocker; N/A, not available; ALT, alanine aminotransferase; AST, aspartate aminotransferase; NAT, nucleic acid testing; ARDS, acute respiratory distress syndrome.
