  • Descrição: Objective: This study aimed to reveal whether patients with thalassemia major, who were followed up in our clinic, were given information about hematopoietic stem cell transplantation (HSCT) preparations, results, and complications. Materials and Methods: A total of 190 patients diagnosed with thalassemia major between 1991 and 2019 at the Pediatric Hematology-Oncology Clinics of Istanbul Kanuni Sultan Suleyman Education and Research Hospital were retrospectively analyzed. Results: Median age of the patients and follow-up time were 9 years (range 1-5) and 42.9 months (range 1-285), respectively. The IVSI-110 was the most frequently (30.4%) encountered mutation; there was no information about HSCT in 28 patients’ files, 36 patients had no human leucocyte antigen-matched donors, and 38 patients had undergone HSCT. Pretransplant median ferritin levels in thalassemia major patients who had undergone HSCT and who had not undergone HSCT were 1751 ng/mL (350–4000) and 1300 ng/mL (396-4000) (P = .149), respectively. The median age of HSCT was 6.5 years, and 24 patients were transplanted from human leucocyte antigen-matched sibling donors, 8 from human leucocyte antigen-matched family donors, and 5 patients from human leucocyte antigen-matched unrelated donors with the myeloablative conditioning regimen. Acute and chronic complication rate was higher in patients transplanted from human leucocyte antigen-matched family donors compared to human leucocyte antigen-matched sibling donors (50% vs 28% and 60% vs 8.3%), respectively; complication odd ratio was 6.7 (%95 CI 1.4-32). Conclusion: Human leukocyte antigen typing, donor search, and timely information about HSCT were noted to be performed in two-thirds of the thalassemia major patients, and around half of the patients underwent HSCT. Both acute and chronic complications were significantly higher in patients transplanted from matched unrelated donors.
