Öğe Acute kidney injury in Turkey: epidemiological characteristics, etiology, clinical course, and prognosis(Bmc, 2022) Gursu, Meltem; Yegenaga, Itir; Tuglular, Serhan; Dursun, Belda; Bek, Sibel Gokcay; Bardak, Simge; Onan, EnginBackground This study aimed to evaluate the etiologies, comorbidities, and outcomes of acute kidney injury (AKI) in Turkey and determine any potential differences among different geographical parts of the country. Methods This prospective observational study was conducted by the Acute Kidney Injury Working Group of the Turkish Society of Nephrology. Demographical and clinical data of patients with AKI at the time of diagnosis and at the 1(st) week and 1(st), 3(rd), and 6(th) months of diagnosis were evaluated to determine patient and renal survival and factors associated with patient prognosis. Results A total of 776 patients were included (54.7% male, median age: 67 years). Prerenal etiologies, including dehydration, heart failure, and sepsis, were more frequent than other etiologies. 58.9% of the patients had at least one renal etiology, with nephrotoxic agent exposure as the most common etiology. The etiologic factors were mostly similar throughout the country. 33.6% of the patients needed kidney replacement therapy. At the 6(th) month of diagnosis, 29.5% of the patients had complete recovery; 34.1% had partial recovery; 9.5% developed end-stage kidney disease; and 24.1% died. The mortality rate was higher in the patients from the Eastern Anatolian region; those admitted to the intensive care unit; those with prerenal, renal, and postrenal etiologies together, stage 3 AKI, sepsis, cirrhosis, heart failure, and malignancy; those who need kidney replacement therapy; and those without chronic kidney disease than in the other patients. Conclusion Physicians managing patients with AKI should be alert against dehydration, heart failure, sepsis, and nephrotoxic agent exposure. Understanding the characteristics and outcomes of patients with AKI in their countries would help prevent AKI and improve treatment strategies.Öğe COULD MESANGIAL C3 DEPOSITION BE AN INDEPENDENT PROGNOSTIC MARKER IN IMMUNOGLOBULIN A NEPHROPATHY?(Oxford Univ Press, 2023) Cetinkaya, Hakki; Gursu, Meltem; Yazici, Halil; Cebeci, Egemen; Eren, Necmi; Altiparmak, Mehmet Riza; Akcay, Omer Faruk[Abstract Not Availabe]Öğe COVID-19 Infection in Peritoneal Dialysis Patients: A Comparative Outcome Study with Patients on Hemodialysis and Patients without Kidney Disease(Aves, 2022) Kazancioglu, Rumeyza; Ozturk, Savas; Turgutalp, Kenan; Gursu, Meltem; Arici, Mustafa; Oruc, Aysegul; Ahbap, ElbisObjectives: There is limited data about coronavirus disease-19 (COVID-19) characteristics and results in peritoneal dialysis (PD) patients. This study aimed to investigate the characteristics and outcomes among PD patients and compare them with matched hemodialysis (HD) patients and a control group without kidney disease. Methods: We included 18 PD patients and consecutive age- and gender-matched 18 HD and 18 patients without kidney disease (control group) registered into the Turkish Society of Nephrology database including 1301 COVID-19 patients. We compared demographic, clinical, radiological, laboratory data, and outcomes namely intensive care unit (ICU) admission, mechanical ventilation, mortality, and composite outcome (death and/or ICU admission). Results: ICU admission, mechanical ventilation, and mortality rates in PD patients (27.8%, 22.2%, and 22.2%, respectively) and the HD group (16.7%, 11.1%, and 16.7%, respectively) were higher than the control group (11.1%, 11.1%, and 5.6%, respectively), but intergroup comparison did not reveal difference. A total of 11 (20.3%) patients had composite outcome (6 PD patients, 3 HD patients, and 2 patients in the control group). In Cox regression analysis, higher age and higher CRP level were related to increased risk of composite outcome. Adjusted rate of composite outcome in PD group was significantly higher than the control group (P =.050). This rate was similar in HD and control groups (P =.30). Conclusions: Combined in-hospital mortality and/or ICU admission of PD patients with COVID-19 was significantly higher than the control patients. There is a need for careful surveillance of PD patients for infection signs and prompt treatment of COVID-19.Öğe THE EFFECT OF GLOMERULAR C3 DEPOSITION ON RENAL OUTCOME IN PATIENTS WITH MEMBRANOUS NEPHROPATHY: DATA OF THE TSN-GOLD STUDY(Oxford Univ Press, 2023) Gursu, Meltem; Ceheci, Egemen; Turkmen, Aydin; Dervisoglu, Erkan; Sezen, Mehnet; Turgutalp, Kenan; Sahin, Gulizar Manga[Abstract Not Availabe]
