Abstract Background Chronic kidney disease (CKD) and immunosuppression, such as in renal transplantation (RT), stand one of the established potential risk factors for severe coronavirus 2019 (COVID-19). Case morbidity mortality rates any type infection have always been much higher CKD, haemodialysis (HD) RT patients than general population. A large study comparing COVID-19 outcome moderate to advanced CKD (Stages 3–5), HD with a control group is still lacking. Methods We conducted...
Abstract Background Maintenance hemodialysis (MHD) patients are at increased risk for coronavirus disease 2019 (COVID-19). The aim of this study was to describe clinical, laboratory, and radiologic characteristics determinants mortality in a large group MHD hospitalized COVID-19.

Acute kidney injury (AKI) is common in coronavirus disease-2019 (COVID-19) and the severity of AKI linked to adverse outcomes. In this study, we investigated factors associated with in-hospital outcomes among hospitalized patients COVID-19 AKI.
Abstract Background We aimed to determine the risk factors that may be associated with colistin-induced acute kidney injury (AKI) promote safer use of colistin in treatment nosocomial infections caused by multidrug-resistant Gram-negative bacteria intensive care units. Materials and methods This retrospective observational study was conducted among adult patients who received a minimum 48 h intravenous from January 2020 December at unit tertiary hospital. AKI diagnosis staging were made...

Abstract Background The most common cause of end-stage kidney disease is diabetes mellitus (DM). commonly used renal replacement therapy in our country and many countries around the world hemodialysis (HD). Glycemia control important these populations. In this study, we aimed to screen for glycemic complications a large population diabetic HD patients country. Methods 16043 were screened 253 dialysis centers Turkey. 5038 included study. At participating centers, patients' history,...
Purpose: The success of solid organ transplantation and the consequent increase in patients on waiting list has led to an increased utilization donor kidneys with a high kidney profile index (KDPI)/expanded criteria. In our study, who underwent based standard expanded criteria were compared terms factors affecting graft survival. Data from cadavers extended (SCD, ECD) between 01 July 2011 30 June 2016 evaluated retrospectively. Donor characteristics, treatment type, response 1st-, 3rd-,...
Hemodialysis (HD) patients have increased risk for short-term adverse outcomes of COVID-19. However, complications and survival at the post-COVID-19 period not been published extensively.We conducted a national, multicenter observational study that included adult maintenance HD recovered from confirmed A control group without COVID-19 was selected in same center. We investigated characteristics follow-up compare them with non-COVID-19 group.A total 1223 (635 group, 588 group) 47 centers were...
Detection of potential Fabry disease patients before appearance life-threatening findings is great importance, particularly in high-risk populations. This study was designed to determine prevalence among Turkish undergoing peritoneal dialysis and hemodialysis for chronic renal failure (CRF).A total 1,527 (mean (SD) age: 60.2 (14.2) years, 55.5% were males) on (n = 1,435) or 92) CRF included this multicenter conducted at 17 centers across Bursa province, Turkey.
