An X-linked severe combined immunodeficient (SCID) patient received a nonirradiated erythrocyte transfusion and developed transfusion-associated graft-versus-host disease (TAGVHD), which was controllable with high-dose corticosteroids. Haplo-identical SCT was performed, after a myeloablative conditioning regimen. At day +26, he developed GVHD. Chimerism studies revealed DNA of the erythrocyte transfusion donor (ETD) and recipient only. Because of early nonengraftment and the presence of alloreactive T cells of ETD origin, the patient was treated with an immunosuppressive conditioning regimen followed by a second SCT from the same donor. While tapering immunosuppression, he again developed mild GVHD, and DNA of ETD and bone marrow donor origin were both present. On cyclosporin, the ETD-DNA signal finally disappeared. High-resolution HLA typing revealed haplo-identity between BMD, ETD and the patient, which might have contributed to the relative mild course of the TAGVHD.

Objective: Graft-versus-host disease (GVHD) is an immune phenomenon that occurs in 30 to 70% of patients after allogeneic hematopoietic stem cell transplantation (HST). Chronic GVHD is a state of immune dysregulation wherein, depending on the severity and organ involved, patients may require prolonged treatment with additional or higher corticosteroids and other immunosuppressive agents. The objective of this study was to review the endocrine manifestations following HST that can arise as a consequence of the primary disease or its treatment, including chemotherapeutic agents, corticosteroids, radiation, or GVHD. Methods: We performed a narrative review of GVHD after HST. An English-language search for relevant studies was conducted on PubMed from inception to August 1, 2018, using the following search terms: "endocrine complications," "bone marrow transplantation," "graft-versus-host disease," and "GVHD." The reference lists of relevant studies were also reviewed. Results: Chronic GVHD may be associated with considerable pediatric growth impairment and may also contribute to thyroid gland dysfunction and thyroid cancer. These patients may also be at increased risk for low bone mineral density, reduced fertility, metabolic syndrome, and suppression of the pituitary-adrenal axis with adrenal insufficiency. Conclusion: This review indicates the importance of monitoring, diagnosing, and properly treating the endocrine complications in this population. More studies are needed to investigate the independent impact of GVHD on the endocrine system and treatment for complications. Abbreviations: BMD = bone mineral density; GH = growth hormone; GVHD = graft-versus-host disease; HST = hematopoietic stem cell transplantation; IGF-1 = insulin-like growth factor 1.
