A Successful Renal Transplant in a Pediatric Patient With Glanzmann Thrombasthenia and Hyperimmunization

Abstract

We report the case of a patient with type 2 Glanzmann thrombasthenia who underwent successful kidney transplant with his mother's kidney. He started dialysis at 13 months. The patient had been diagnosed with Glanzmann thrombasthenia at 9 years old, after hemorrhagic shock, during which multiple transfusions were required and hyperimmunization had developed. At 12 years old, he received a kidney transplant. Before transplant, ABO- and HLA-compatible platelet donors were identified and convened to donate forthe surgery and in case of emergency. Bleeding was prevented withprophylacticHLA-matched platelet transfusion and tranexamic acid. After transplant, diuresis started immediately with excellent graft function and no severe bleeding. However, after week 5, several episodes of macroscopic hematuria occurred, with obstruction and anuria. The double J ureteric stent was replaced 4 times in 2 months. Finally, the ureteric stent was removed 9 months later. At 22 months after kidney transplant, the patient has a normal graft function and no further bleeding has occurred, underlying the importance of multidisciplinary management.
