Abstract
BACKGROUND

Hematopoietic stem cell transplantation (HSCT) is widely used in the treatment of hematological diseases. However, complications after transplantation, such as acute and chronic graft-vs-host disease (GVHD), still seriously affect the quality of life and even threaten the lives of patients. There is evidence that glomerular diseases can manifest as GVHD. However, GVHD should not occur as a result of syngeneic HSCT.

CASE SUMMARY

A 20-year-old male diagnosed with T lymphoblastic lymphoma (stage IIIA, aaIPI 1) in September 2013 was treated with six cycles of hyper-CVAD and achieved complete remission. He underwent syngeneic HSCT in June 2014, and had no kidney disease history before the transplant. However, nephrotic syndrome occurred 24 mo later in the patient after syngeneic HSCT. Renal biopsy was performed, which led to a diagnosis of atypical membranous nephropathy. After treatment with glucocorticoids combined with cyclophosphamide and cyclosporine, the nephrotic syndrome was completely relieved.

CONCLUSION

We report a case of delayed nephrotic syndrome after syngeneic HSCT. Antibody-mediated autoimmune glomerular disease may be the underlying mechanism. After treatment with immunosuppressive agents, the nephrotic syndrome was completely relieved but further long-term follow-up is still needed.

Core Tip: Postoperative complications such as acute and chronic graft-vs-host disease (GVHD) seriously affect the quality of life of patients after transplantation and even threaten patients’ lives. There is evidence that glomerular diseases may manifest as GVHD. However, GVHD should not occur as a result of syngeneic hematopoietic stem cell transplantation (HSCT). We report a rare case of delayed nephrotic syndrome following syngeneic HSCT for treatment of T lymphoblastic lymphoma. Nephrotic syndrome occurred 24 mo later. Renal biopsy was performed, which led to a diagnosis of atypical membranous nephropathy. After treatment with glucocorticoids combined with cyclophosphamide and cyclosporine, the nephrotic syndrome was completely relieved. The specific pathogenesis of nephrotic syndrome in this case is unclear but some findings may support the role of induction of the autoimmune response after transplantation.
