RESUMEN
Background/aim: The COVID-19 infection, which started in Wuhan City, China, in December 2019, turned into a pandemic in a very short time, affecting mainly the elderly and those with serious chronic illnesses. COVID-19 infections have been observed to have a high mortality rate, especially in patients undergoing maintenance hemodialysis. Materials and methods: Forty-two patients over 18 years of age who underwent a maintenance hemodialysis program at our unit, who tested positive for COVID-19 by PCR from nasopharyngeal swabs, and/or who were observed to have disease-related signs in their CTs were included in the study. Results: In this study, 23 of 42 patients receiving hemodialysis support in our clinic were included. The median age was 67 years old (min: 35; max: 91 years), and all of our patients had primary hypertension and other comorbidities. Their clinical evaluation showed that dry cough (47.8%) and shortness of breath (47.8%) were the most common symptoms. Fever was less pronounced (30.4%). The median time from the onset of symptoms to hospitalization was 1 day (min: 0; max:), and the time from hospitalization to death was 18 days (min: 1; max: 22). Transfer from the inpatient ward to the ICU took a median of 7 days (min: 1; max: 13). Among the 23 patients, 3 died during follow-up, and 20 were discharged with full recovery. Baseline ferritin, procalcitonin levels, and CRP/albumin rates were higher, and neutrophil/lymphocyte levels were lower in patients who eventually died. In these patients, despite being nonsignificant, there were more diabetic patients, and the D-dimer levels were higher than 1000 ugFEU/L. Conclusion: The COVID-19 infection is associated with increased mortality in chronic kidney diseases patients. Despite being nonsignificant, there was a trend towards increased mortality in patient with diabetes, D-dimer levels >1000 ugFEU/L, higher ferritin and prokalsitonin levels, an increased CRP/albumin ratio, and a lower neutrophil/lymphocyte ratio.

OBJECTIVE: To determine clinical characteristics, renal replacement therapy (RRT) requirements, and predictors of mortality in critically ill patients with COVID-19 associated AKI. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Sakarya University Education and Training Hospital, Sakarya, Turkey, between April 1 and 30, 2020. METHODOLOGY: The study included 55 patients who were admitted with diagnosis of COVID-19, and whose illnesses showed a critical course that leads to AKI. The variables were studied as per objective. RESULTS: During the follow-up, 43 out of 55 patients (78.2%) died and 12 (21.8%) were discharged with recovery. The mortality was higher in patients at stage 3 (88.9% mortality) compared to stage 2 (53.8% mortality) (p=0.014). In the nonsurvivor group, RDW (red cell distribution width) and albumin levels were lower at admission; whereas, the LDH levels and CRP/albumin ratios were higher. On regression analysis, low albumin level (OR: 12.793, p = 0.010), high LDH level (OR: 8.454, p = 0.026), and presence of stage 3 AKI (OR: 10.268, p = 0.020) were found as independent risk factors for mortality in COVID-19 patients, who developed AKI. CONCLUSION: In critically ill patients with COVID-19 pneumonia, who developed AKI, it was seen that the presence of low albumin, high LDH, and stage 3 AKI at the time of admission could be used as predictors of mortality. Moreover,, it was shown for the first time that in these patients, the high CRP/albumin ratio and low RDW could be associated with mortality. Key Words: Acute kidney injury, Mortality, COVID-19.
