Epstein-Barr virus-associated lymphoproliferative disease during remission after induction therapy with dasatinib in Philadelphia chromosome-positive acute lymphoblastic leukemia: a case report.

Dasatinib, a second-generation tyrosine kinase inhibitor, has been reported to have immunomodulatory effects. Epstein-Barr virus (EBV)-associated lymphoproliferative disorders (EBV-LPD) occur in immunocompromised patients, such as those receiving methotrexate or other immunosuppressive drugs or after allogenic transplantation. EBV-LPD is also reported to be a rare side effect in patients receiving long-term dasatinib or imatinib.

Type II Cryoglobulinemic Membranoproliferative Glomerulonephritis Caused by Mucosa-associated Lymphoid Tissue Lymphoma.

A 67-year-old man complained of lower limb edema with a purpuric skin rash. Laboratory tests revealed proteinuria, elevated serum creatinine levels, and low serum albumin levels.

[HLA-haploidentical peripheral blood stem cell transplantation with post-transplantation cyclophosphamide for adult T-cell leukemia].

Recently, allogeneic peripheral blood stem cell transplantation from human leukocyte antigen (HLA)-haploidentical donors using post-transplantation cyclophosphamide (PTCY-haploPBSCT) has become available in clinical practice. However, the efficacy of PTCY in adult T-cell leukemia (ATL) is not fully established yet. In this study, we retrospectively examined data of seven patients who underwent PTCY-haploPBSCT.
