Abstract Background and objective: With the widespread use of allogeneic hematopoietic stem cell transplantation (allo-HSCT), long-term complications have come to the fore. The aim of this study was to determine the prevalence and risk factors of chronic kidney disease (CKD) developing in the long term in patients who underwent allo-HSCT in childhood and also to investigate the superiority of eGFR formulas. Methods: The present study evaluated CKD in patients who underwent allo-HSCT. We analyzed the 94 children who received allo-HSCT at the Ege University in İzmir between August and November, 2019. The patients were evaluated at 2 years after transplantation. CKD was defined as a glomerular filtration rate (GFR) <90 mL/min/1.73 m2 using eGFR equations based on serum creatinine (SCr), cystatin C (CysC), and SCr plus CysC. Results: In our study, 9 (9.4%), according to Bedside Schwartz, 59 (76.6%), according to CKiD-eGFR-CysC, and 20 (26%) patients, according to CKiD-eGFR-SCr-CysC equations were identified with CKD. In cases identifies as CKD according to CysC, early development of acute kidney injury (AKI), post-transplant cytomegalovirus (CMV) reactivation and being >120 months during transplantation were found to be associated with the development of CKD. Conclusion: We may be delayed in detecting CKD by calculating SCr-based formulas in allo-HSCT cases, which is a patient group where early diagnosis and treatment of CKD is very important.
