Objectives: Viral infections are the leading cause of posttransplant morbidity and mortality. We aimed to determine the effect on graft function, the risk factors, the frequency, and types of viral infections and to evaluate the effect of viral infections on kidney and patient outcomes in pediatric kidney transplant patients.

Materials And Methods: Records of children undergoing kidney transplant in our center during the period February 1, 2010, to December 31, 2023, were retrospectively evaluated.

Background: Crush Syndrome is a major cause of morbidity and mortality following large-scale catastrophic earthquakes. Since there are no randomized controlled studies on Crush Syndrome, knowledge on this subject is limited to expert experience. The primary objective is to analyze the epidemiological and demographic characteristics, clinical outcomes, and mortality factors of earthquake victims after the Pazarcik and Elbistan earthquakes on February 6, 2023.

Article Synopsis
  • Two devastating earthquakes in Türkiye on February 6, 2023, resulted in significant injuries to 903 children, with a focus on crush syndrome-related acute kidney injury (Crush-AKI) and mortality.
  • The study tracked various factors, including the time under rubble, treatment protocols, and patient outcomes, revealing that Crush-AKI developed in 36% of the patients, and over half required dialysis.
  • Key findings included that serum levels of creatine phosphokinase above 20,950 U/L and inadequate initial intravenous fluid volume were linked to Crush-AKI, and most deaths occurred among those with Crush-AKI within the first four days of admission.

Background: Primary hyperoxaluria type 1 (PH1) is characterized by increased endogenous oxalate production and deposition as calcium oxalate crystals. The main manifestations are nephrocalcinosis/nephrolithiasis, causing impaired kidney function. We aimed to evaluate the clinical characteristics and overall outcomes of paediatric PH1 patients in Turkey.

Article Synopsis
  • Immunoglobulin A vasculitis with nephritis (IgAVN) is the most common vasculitis in children, and this study aimed to analyze clinical outcomes, treatments, and risk factors in a large cohort of 1148 children diagnosed with the condition.
  • The retrospective analysis revealed that poorer outcomes were associated with factors like older age, lower kidney function at onset, hypertension, and certain kidney damage features, but no specific treatment was found to be more effective than others.
  • The study concluded that there is a need for further research and clinical trials to determine effective treatments and improve health outcomes for children with IgAVN.
