Comparison of Anti-Mullerian Hormone Levels Pre- and Post-Hematopoietic Cell Transplantation in Pediatric and Adolescent Females with Sickle Cell Disease.

ABSTRACT

Allogeneic hematopoietic cell therapy (HCT) is an established cure for sickle cell disease (SCD); however, HCT conditioning regimens are known to be gonadotoxic. Anti-mullerian hormone (AMH) measures ovarian reserve, and follicle-stimulating hormone (FSH) defines premature ovarian insufficiency (POI) at values >40 mIU/mL in pubertal females. The present study was conducted to assess ovarian reserve and function before and after transplantation in pediatric and adolescent females with SCD treated with allogeneic HCT between January 2015 and June 2020 at Children's Healthcare of Atlanta. In this retrospective review of 17 females age <21 years with SCD who had AMH levels measured at baseline and at 2 years post-HCT, AMH levels were categorized as normal, low, or undetectable, and FSH levels were measured and used to identify pubertal females who had developed POI. Demographic and treatment data were abstracted from the institutional database and medical records, and a descriptive statistical analysis was conducted. Of the 17 patients in the study cohort, 14 had been treated with hydroxyurea and 3 had chronic transfusions but with no significant iron overload. AMH levels were normal in 15 patients (88%) and low in 2 patients (12%) at baseline. The median age at HCT was 7.5 years (range, 3.7 to 20.3 years), and 14 patients (82%) underwent matched related donor HCT. After HCT, 15 patients (88%) had undetectable AMH and 2 (12%) had low AMH, with no apparent differences by HCT conditioning regimen. No pubertal patients had POI at baseline, whereas 55% of pubertal patients had progressed to POI by 2 years post-HCT. In this cohort, the majority of females had normal AMH levels at baseline but undetectable levels after HCT. Females with SCD considering HCT should be counseled about the treatment-related risk of gonadal dysfunction. © 2022 American Society for Transplantation and Cellular Therapy.
