CHARACTERISTICS AND SURVIVAL RESULTS OF PERITONEAL DIALYSIS PATIENTS SUFFERING FROM COVID-19 IN TURKEY: A MULTICENTER NATIONAL STUDY

INTRODUCTION: We aimed to study the characteristics of peritoneal dialysis (PD) patients with coronavirus disease-19 (COVID-19), determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome. METHODS: In this multicenter national study, we included PD patients with confirmed COVID-19 from 27 centers. The baseline demographic, clinical, laboratory, and radiological data and outcomes at the end of the first month were recorded. RESULTS: We enrolled 142 COVID-19 patients (median age: 52 years). 58.2% of patients had mild disease at diagnosis. Lung involvement was detected in 60.8% of patients. Eighty-three (58.4%) patients were hospitalized, 31 (21.8%) patients were admitted to intensive care unit and 24 needed mechanical ventilation. Fifteen (10.5%) patients were switched to hemodialysis and hemodiafiltration was performed for four (2.8%) patients. Persisting pulmonary symptoms (n = 27), lower respiratory system infection (n = 12), rehospitalization for any reason (n = 24), malnutrition (n = 6), hypervolemia (n = 13), peritonitis (n = 7), ultrafiltration failure (n = 7), and in PD modality change (n = 8) were reported in survivors. Twenty-six patients (18.31%) died in the first month of diagnosis. The non-survivor group was older, comorbidities were more prevalent. Fever, dyspnea, cough, serious-vital disease at presentation, bilateral pulmonary involvement, and pleural effusion were more frequent among non-survivors. Age (OR: 1.102; 95% CI: 1.032–1.117; p: 0.004), moderate-severe clinical disease at presentation (OR: 26.825; 95% CI: 4.578–157.172; p < 0.001), and baseline CRP (OR: 1.008; 95% CI; 1,000–1.016; p: 0.040) were associated with first-month mortality in multivariate analysis. DISCUSSION/CONCLUSIONS: Early mortality rate and medical complications are quite high in PD patients with COVID-19. Age, clinical severity of COVID-19, and baseline CRP level are the independent parameters associated with mortality

ACUTE KIDNEY INJURY IN HOSPITALIZED COVID-19 PATIENTS: A MULTICENTRE STUDY BY TURKISH SOCIETY OF NEPHROLOGY

BackgroundAcute kidney injury (AKI) is common in coronavirus disease-2019 (COVID-19) and theseverity of AKI is linked to adverse outcomes. In this study, we investigated the factors asso-ciated with in-hospital outcomes among hospitalized patients with COVID-19 and AKI.MethodsIn this multicenter retrospective observational study, we evaluated the characteristics andin-hospital renal and patient outcomes of 578 patients with confirmed COVID-19 and AKI.Data were collected from 34 hospitals in Turkey from March 11 to June 30, 2020. AKI defini-tion and staging were based on the Kidney Disease Improving Global Outcomes criteria.Patients with end-stage kidney disease or with a kidney transplant were excluded. Renaloutcomes were identified only in discharged patients.ResultsThe median age of the patients was 69 years, and 60.9% were males. The most frequentcomorbid conditions were hypertension (70.5%), diabetes mellitus (43.8%), and chronic kid-ney disease (CKD) (37.6%). The proportions of AKI stages 1, 2, and 3 were 54.0%, 24.7%,and 21.3%, respectively. 291 patients (50.3%) were admitted to the intensive care unit.Renal improvement was complete in 81.7% and partial in 17.2% of the patients who weredischarged. Renal outcomes were worse in patients with AKI stage 3 or baseline CKD. Theoverall in-hospital mortality in patients with AKI was 38.9%. In-hospital mortality rate was notdifferent in patients with preexisting non-dialysis CKD compared to patients without CKD(34.4 versus 34.0%, p = 0.924). By multivariate Cox regression analysis, age (hazard ratio[HR] [95% confidence interval (95%CI)]: 1.01 [1.0–1.03], p = 0.035], male gender (HR [95%CI]: 1.47 [1.04–2.09], p = 0.029), diabetes mellitus (HR [95%CI]: 1.51 [1.06–2.17], p =0.022) and cerebrovascular disease (HR [95%CI]: 1.82 [1.08–3.07], p = 0.023), serum lac-tate dehydrogenase (greater than two-fold increase) (HR [95%CI]: 1.55 [1.05–2.30], p =0.027) and AKI stage 2 (HR [95%CI]: 1.98 [1.25–3.14], p = 0.003) and stage 3 (HR [95%CI]:2.25 [1.44–3.51], p = 0.0001) were independent predictors of in-hospital mortality.ConclusionsAdvanced-stage AKI is associated with extremely high mortality among hospitalizedCOVID-19 patients. Age, male gender, comorbidities, which are risk factors for mortality inpatients with COVID-19 in the general population, are also related to in-hospital mortality inpatients with AKI. However, preexisting non-dialysis CKD did not increase in-hospital mor-tality rate among AKI patients. Renal problems continue in a significant portion of thepatients who were discharged.&nbsp;</div
