    Incidence and Patient Outcomes in Renal Replacement Therapy After Orthotopic Liver Transplant
    (2017) Ayhan, Asude; Ersoy, Zeynep; Ulas, Aydin; Zeyneloglu, Pinar; Pirat, Arash; Haberal, Mehmet; 0000-0003-0767-1088; 0000-0003-3299-6706; 0000-0002-3462-7632; 0000-0003-2312-9942; 0000-0002-8130-9901; 28260481; AAF-3066-2021; AAJ-2066-2021; AAJ-8097-2021; AAJ-2057-2021; C-3736-2018
    Objectives: Our objective was to evaluate the incidence of renal replacement therapy after orthotopic liver transplant and to evaluate and analyze patient outcomes. Materials and Methods: We performed a retrospective analysis of 177 consecutive patients at a tertiary care unit who underwent orthotopic liver transplant between January 2010 and June 2016. Patients who were admitted to the intensive care unit after orthotopic liver transplant and who required renal replacement therapy were included. Results: A total of 177 (79 adult, 98 pediatric) orthotopic liver transplants were performed during the study period. Of these, 35 patients (19%) required renal replacement therapy during the early posttrans plantation period. After excluding 5 patients with previous chronic renal failure, 30 patients (17%; 20 adult [25%], 10 pediatric [10%]) with acute kidney injury required renal replacement therapy. The mean patient age was 31.1 +/- 20.0 years, with a mean Model for End-stage Liver Disease score of 16.7 +/- 12.3. Of the patients with acute kidney injury who underwent renal replacement therapy, in-hospital mortality was 23.3% (7 of 30 patients), and 40% remained on dialysis. No significant difference was seen in mortality between early versus delayed initiation of renal replacement therapy in patients with stage 3 acute kidney injury (P = .17). Conclusions: Of liver transplant recipients who present with acute kidney injury, 19% require renal replacement therapy, and in-hospital mortality is 20% in the early postoperative period.

    A model for acute kidney injury in severe burn patients
    (2022) Karakaya, Emre; Akdur, Aydincan; Aydogan, Cem; Turk, Emin; Sayin, Cihat Burak; Soy, Ebru Ayvazoglu; Yucebas, Sait Can; Alshalabi, Omar; Haberal, Mehmet; 0000-0002-4879-7974; 0000-0002-8726-3369; 0000-0002-8726-3369; 0000-0002-0993-9917; 0000-0002-3462-7632; 33879373; AAD-5466-2021; AAA-3068-2021; AAA-3068-2021; AAC-5566-2019; AAJ-8097-2021
    Introduction: In patients with severe burns, morbidity and mortality are high. One factor related to poor prognosis is acute kidney injury. According to the AKIN criteria, acute kidney injury has 3 stages based on urine output, serum creatinine level, and renal replacement therapy. In this study, we aimed to create a decision tree for estimating risk of acute kidney injury in patients with severe burn injuries. Methods: We retrospectively evaluated 437 adult patients with >20% total burn surface area injury who were treated at the Baskent University Ankara and Konya Burn Centers from January 2000 to March 2020. Patients who had high-voltage burn and previous history of kidney disease were excluded. Patient demographics, medical history, mechanism of injury, presence of inhalation injury, depth of burn, laboratory values, presence of oliguria, need for renal replacement therapy, central venous pressure, and prognosis were evaluated. These data were used in a "decision tree method" to create the Baskent University model to estimate risk of acute kidney injury in severe burn patients. Results: Our model provided an accuracy of 71.09% for risk estimation. Of 172 patients, 78 (45%) had different degrees of acute kidney injury, with 26 of these (15.1%) receiving renal replacement therapy. Our model showed that total burn surface area was the most important factor for estimation of acute kidney injury occurrence. Other important factors included serum creatinine value, burn injury severity score, hemoglobin value, neutrophil-tolymphocyte ratio, and platelet count. Conclusion: The Baskent University model for acute kidney injury may be helpful to determine risk of acute kidney injury in burn patients. This determination would allow appropriate treatment to be given to high-risk patients in the early period, reducing the incidence of acute kidney injury. (c) 2021 Published by Elsevier Ltd.
