BACKGROUND AND AIMS: Our Nephrology Department during spring period on the first wave of COVID-19 was the referral Dialysis Unit for Covid-19 positive HD patients in the district area of Athens, Greece. The aims of this study are to report characteristics, rates and outcomes of all patients affected by infection with SARS-CoV-2 undergoing HD and treated under our care METHOD: This is an observational study. Our Dialysis Unit has been assigned as a referral unit for Covid-19 positive HD patients. We registered all the data regarding the clinical course of our patients population. Age, primary cause of end stage renal disease, weight, clinical presentation, HD history, outcome, days of hospitalization. RESULTS: 22 Covid-19 positive HD patients were treated under the care of our facility during the period 8 April 2020-17 June 2020. 16 patients were symptomatic at admission and 13 patients admitted with or developed during their stay pleural effusions. 12 patients (8 male) of our group died during their hospitalization. 3 out of 12 were admitted to Intensive Care Unit (ICU). 6 patients were septic, 4 had respiratory failure and 2 developed cardiovascular events. 14.5 days were the mean hospitalization days (range: 1-38 days) for the diceased ones. 2 out of 3 patients that admitted to ICU had quick deterioration, incubated and stayed in ICU for 48 hours. The third one with severe cormobidities (multiple myeloma, cancer of bladder) developed respiratory failure after 8 days of hospitalization, incubated, became septic and died after 20 days in ICU. Mean age of our patients was 74.5 years. It has to be pointed out that 13 patients were over 75 years old. Mean age was higher in those who died compared with those who were discharged with double negative Covid-19 tests (79 vs 74,5 years old respectively). Median dialysis vintage for our patients was 63 months and for the diceased ones was 89 months. Average weight of our patients was 69 kgrs. Weight of diceased patients was 63 kgrs. 11 out of 22 patients and 5 out of 12 diceased patients were diabetic. 14 patients were hypertensive and 16 had official cardiovascular backround. 10 out of total 22 patients under our care discharged after 43 days of hospitalization (range:35-56 days). CONCLUSION: As a conclusion our data provide clues regarding out experience of caring HD patients with COVID-19. Mortality was high. It seems that despite the fact that immune response of this population has not been clearly clarified, age, cormobidities and above all end-stage renal disease by its self is a significant and unpredictable risk factor for clinical outcome of HD patients with COVID-19 infection.
