Long-term complete remission of early hematological relapse after discontinuation of immunosuppressants following allogeneic transplantation for Sezary syndrome
Sezary syndrome (SS) is a leukemic form of cutaneous T-cell lymphoma and is chemo-resistant. Allogeneic hematopoietic stem cell transplantation is a promising therapy for SS; however, relapse is common. Therapeutic options after relapse have not been established. We managed an SS patient with hematological relapse within one month after transplantation. After discontinuation of immunosuppressants, she achieved complete remission and remained relapse-free. The chimeric analyses of Tcells showed that the full recipient type became complete donor chimera after immunological symptoms. This clinical course suggested that discontinuation of immunosuppressants may result in a graftversus- tumor effect, leading to the eradication of lymphoma cells
Successful intrathecal chemotherapy combined with radiotherapy followed by pomalidomide and low-dose dexamethasone maintenance therapy for a primary plasma cell leukemia patient
Primary plasma cell leukemia (PPCL) is a rare aggressive variant of plasma cell disorder and frequently presents with extramedullary disease. Central nervous system (CNS) involvement with PPCL has an extremely poor prognosis. We describe a 46-year-old man with PPCL treated with a combination of lenalidomide, bortezomib, and dexamethasone as induction therapy following upfront allogeneic stem cell transplantation (allo-SCT). Despite achieving a very good partial response, the patient suffered from an isolated CNS relapse 12 months after allo-SCT. He was immediately started on concurrent intrathecal chemotherapy (IT) and cranial irradiation (RT). Subsequently, pomalidomide and low-dose dexamethasone (Pd) were given as maintenance therapy. He has been without CNS recurrence for more than 18 months. Our case suggests that concurrent IT and RT followed by Pd maintenance therapy may be an effective option to control CNS relapse of PPCL after allo-SCT

Administration of combined venetoclax and azacitidine in a patient with acute myeloid leukemia and multiple comorbidities undergoing dialysis: A case report
Abstract Patients with acute myeloid leukemia (AML) who have comorbidities have limited treatment options, thereby resulting in poor prognosis. Venetoclax, a specific B‐cell lymphoma‐2 inhibitor, has recently been approved for AML in combination with hypomethylating agents; however, only one report has described its use in patients undergoing dialysis. Herein, we report the effectiveness of combined venetoclax and azacitidine in a 73‐year‐old man with AML undergoing dialysis and who was ineligible for standard therapies. The safety of venetoclax and azacitidine in patients undergoing dialysis has been reported, and their combination may be a feasible option for patients with AML undergoing dialysis

Sudden Cardiac Death in a Patient with Thrombotic Thrombocytopenic Purpura: A Case Report
A 49-year-old female was admitted to our hospital with malaise and gross hematuria. As ADAMTS13 (a disintegrin-like and metalloproteinase with thrombospondin type 1 motifs 13) activity was absent and the ADAMTS13 inhibitor was detected, she was diagnosed with acquired thrombotic thrombocytopenic purpura (TTP). In addition to plasma exchange and corticosteroid therapy, she received rituximab therapy for inhibitor boosting but died suddenly of a cardiac arrest on day 9. The postmortem revealed microvascular platelet thrombi in multiple organs. In this case, the deterioration of the patient’s clinical status was considered to have been caused by inhibitor boosting-induced systemic microvascular occlusion. In particular, her sudden death may have been due to cardiovascular microthrombosis. Since inhibitor boosting can cause TTP patients to deteriorate rapidly, it is crucial to manage TTP patients who undergo inhibitor boosting appropriately. The monitoring of cardiac complications in TTP patients may also be essential, especially in the acute phase
Refractory ascites with liver fibrosis developed in late phase allogeneic hematopoietic stem cell transplantation: report of three patients
We report cases of three patients of refractory ascites without other fluid retention that occurred around five months after allogeneic hematopoietic stem cell transplantation (allo- HSCT). All three patients expired and postmortem examinations revealed unexpected liver fibrosis lacking histological evidences of graft-versus-host-disease (GVHD). The three patients showed normal hepatic function and size before transplantation. During their clinical courses, serum biochemistry test showed no elevation of hepatic enzymes and bilirubin; however, imaging studies demonstrated hepatic atrophy at the onset of ascites. One of the liver specimens showed bile obstruction, which could be seen in hepatic damage by GVHD. Although ascites resulting from venoocclusive disease in early phase allo-HSCT is well documented, ascites associated with hepatic fibrosis in late phase allo-HCST has not been reported. Further clinico-pathological studies on similar patients should be required to ascertain refractory ascites associated with liver fibrosis after allo-HSCT
