Popis: Background and Aims Several chronic medical conditions appear to increase the risk of severe COVID-19. Chronic kidney disease (CKD) patients have a high risk of symptomatic infection and severe respiratory symptoms because of chronic inflammation, uremic toxins accumulation, endothelial dysfunction and an impaired immune response. Even though the presence of one or more comorbidities increases the risk of mortality, information of the outcome of COVID-19 in CKD patients is not yet available. The aim of the study is to present the incidence and outcome of COVID-19 in patients referring to our Nephrology Unit considering CKD patients, dialysis patients and kidney transplant recipients.

Results Our cohort included 52 patients admitted to our Nephrology Unit because of Sars Cov2 infection confirmed by positive reverse transcriptase polymerase chain reaction on nasopharyngeal swab. The mean age was 67.2 ± 13.8 years (range, 33-88 years). Demographic, clinical and radiological features in Table 1. Forty-eight patients (92.3%) underwent chest TC. The main findings were: several bilateral interstitial pneumonia (39 patients, 81.2%), monolateral peripheral ground-glass opacities (6 patients, 12.5%), no signs of pneumonia (3 patients, 6.2 %). Clinical course is highly variable: 18 patients (34.6 %) were asymptomatic, 23 patients (44 %) had a mild course requiring low flux oxygen therapy and 11 patients (21%) presented severe pneumonia and respiratory distress that requires ventilatory support in intensive care unit. Forty patients (70%) had hydroxychloroquine-azithromycin dual therapy, 3 patients (6%) had antiviral therapy in addiction. Sixteen patients (31%) with P/F
