    Introduction: Inflammation is one of the factors involved in the occurrence and progression of acute kidney injury (AKI). We evaluated the relationship between preoperative systemic inflammatory markers and early postoperative AKI development in pediatric liver transplantation (LT) patients. Methods: Data from 190 pediatric patients were retrospectively analyzed. The preoperative neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and pan-immune-inflammation value (PIV) levels were calculated. AKI was classified according to the Kidney Disease: Improving Global Outcomes staging. Patients who did not develop AKI in the early postoperative period were classified as group 0, patients with stage 1 AKI were classified as group 1, and patients with stage 2-3 AKI were classified as group 2. The relationship between the inflammatory parameters and AKI was evaluated. Results: AKI developed in 20% of patients, and 16.31% of these patients had severe AKI. The NLR, SII, and PIV values were significantly higher in patients with severe AKI (p<0.001). Preoperative high PIV values were found to be an independent predictor of AKI development. Conclusion: High preoperative PIV values may be used as a predictive factor for the development of early AKI in patients undergoing pediatric LT.

    Incidence and Risk Factors of Acute Kidney Injury in Pediatric Liver Transplant Patients: A Retrospective Study
    (Jaypee Brothers Medical Publishers Pvt Ltd, 2024) Demiroz, Duygu; Colak, Yusuf Ziya; Ozdes, Oya Olcay; Ucar, Muharrem; Erdogan, Mehmet Ali; Toprak, Huseyin Ilksen; Karakas, Serdar
    Background:Acute kidney injury (AKI) significantly contributes to the mortality and morbidity rates among pediatric liver transplant (LT) recipients. Objective: Our study aimed to assess the potential factors contributing to AKI in pediatric LT patients and to analyze the impact of AKI on postoperative mortality and hospitalization duration. Materials and methods: About 235 pediatric LT patients under the age of 18 between the years 2015 and 2021 were evaluated retrospectively. The relationship between preoperative and intraoperative variables of the patients and AKI developed when the early postoperative period was assessed. Results: A correlation was found between the patients' preoperative age, albumin levels, and AKI. AKI was found to be associated with the duration of surgery and intraoperative blood transfusion. Conclusion: Our findings revealed that the severity of AKI in pediatric LT patients is linked to extended surgical durations and increased blood transfusions resulting from hemodynamically compromised blood loss. Furthermore, independent risk factors for AKI were identified as prolonged warm ischemia and the overall duration of the operation.
