Mycophenolic acid, the active form of mycophenolate mofetil, interferes with IRF7 nuclear translocation and type I IFN production by plasmacytoid dendritic cells.

Background: Both humoral and cellular immune mechanisms are involved in the onset and progression of autoimmune responses in systemic lupus erythematosus (SLE). Plasmacytoid dendritic cells (pDCs) play a central role in the pathogenesis of SLE via the dysregulation of type I interferon (IFN) production; these cells act together with activated myeloid DCs (mDCs) to amplify the vicious pathogenic spiral of autoimmune disorders. Therefore, control of aberrant DC activation in SLE may provide an alternative treatment strategy against this disease.

Clinical efficacy of mogamulizumab for relapsed/refractory aggressive adult T-cell leukemia/lymphoma: A retrospective analysis.

Objectives: Although phase 2 studies have confirmed the efficacy of mogamulizumab for adult T-cell leukemia/lymphoma (ATL), real-world data on its benefits are limited. We assessed the benefits of mogamulizumab for relapsed/refractory ATL in clinical practice.

Methods: We retrospectively analyzed patients with acute- and lymphoma-type ATL.

Evaluation of azacitidine in patients with transplant-ineligible myelodysplastic syndromes and acute myeloid leukemia with myelodysplasia-related changes in a Japanese clinical setting.

Patients with high-risk myelodysplastic syndromes (MDS) treated with azacitidine (AZA) have exhibited improved overall survival. However, information on AZA in real-world settings is limited. The present study retrospectively analyzed 85 patients with MDS treated with AZA.

Effects of recombinant thrombomodulin on long-term prognosis after allogeneic hematopoietic stem cell transplantation.

We investigated the effects of early recombinant thrombomodulin (rTM) treatment on long-term prognosis after hematopoietic stem cell transplantation (HSCT). Subjects included 300 patients who underwent allogeneic HSCT (131 in the rTM(+) group and 169 in the rTM(-) group). The control group received heparin or no anti-coagulation therapy.

A variant of acute promyelocytic leukemia with t(4;17)(q12;q21) showed two different clinical symptoms.

A 63-year-old man was diagnosed with a rare variant of acute promyelocytic leukemia (APL) with t(4;17)(q12; q21) that showed atypical morphological features and two different clinical symptoms. He was started on standard induction chemotherapy for acute myeloid leukemia, which decreased myeloblast numbers; however, APL-like blasts remained. He then received a salvage therapy that added all retinoic acid (ATRA).

Statins can suppress DC-mediated Th2 responses through the repression of OX40-ligand and CCL17 expression.

DCs and epithelial cell-derived thymic stromal lymphopoietin (TSLP) have pivotal roles in allergic inflammation. TSLP stimulates myeloid DCs to express OX40-ligand (OX40L) and CCL17, which trigger and maintain Th2 cell responses. We have previously shown that statins, which are HMG-CoA reductase inhibitors, have the ability to suppress type I IFN production by plasmacytoid DCs.

Neutrophil-to-lymphocyte ratio (NLR) fails to predict outcome of diffuse large B cell lymphoma.

Background: Neutrophil-to-lymphocyte ratio (NLR) has been recognized as a poor prognostic indicator in various solid tumors.

Methods: We retrospectively analyzed 530 patients with de novo DLBCL who were diagnosed from April 2002 to November 2017.

Results: The median age of patients was 69 (range, 20-95) years, and 59% were male.

Evaluation of eltrombopag in patients with aplastic anemia in real-world experience.

Background: Although eltrombopag has recently been approved for treating AA, the effects of its clinical use remain unknown.

Methods: We retrospectively analyzed 11 patients with AA, who had been treated with eltrombopag from August 2017 to May 2018.

Results: Overall response rate was 55%.

Myodesopsia is a symptom of central nervous system blast crisis in chronic myeloid leukemia.

A 49-year-old woman diagnosed with chronic myeloid leukemia in the chronic phase was started on dasatinib treatment, after which she complained of myodesopsia. Nineteen months after diagnosis, the patient again complained of myodesopsia and developed bilateral optic neuritis. Cerebrospinal fluid analysis revealed an increase in blasts, although peripheral blood and bone marrow examination confirmed that the patient remained in a molecular response to tyrosine kinase inhibitor (TKI) therapy.

Clinical significance of dasatinib-induced pleural effusion in patients with de chronic myeloid leukemia.

Dasatinib is currently approved for clinical use as a first-line treatment agent for newly diagnosed chronic myeloid leukemia (CML). However, only a few clinical trials have been performed to evaluate dasatinibinduced PE following first-line therapy. We investigated the incidence and clinical features of dasatinib-induced PE following first-line therapy in Japanese CML patients of real world clinical practice settings.

Combined Use of Ninjin'yoeito Improves Subjective Fatigue Caused by Lenalidomide in Patients With Multiple Myeloma: A Retrospective Study.

Lenalidomide is an immunomodulating derivative of thalidomide, which shows anti-tumor activity against myeloma cells with immunomodulation including augmentation of T-cell and natural killer cell function. Continuous treatment with this agent shows better survival benefit in patients with multiple myeloma and combined lenalidomide with dexamethasone (LEN-DEX) is a standard treatment regimen. However, fatigue is a frequent symptom resulting from lenalidomide administration.

Blastic Epstein-Barr virus associated post-transplant lymphoproliferative disorder after allogeneic stem cell transplantation for severe aplastic anemia.

Post-transplant lymphoproliferative disorder (PTLD) is a well-recognized complication of organ transplantation. Progress has recently been made in the pathological classification of PTLD. However, the clinical course has not been clarified because of the rarity of this disease.

Secondary pure red cell aplasia in multiple myeloma treated with lenalidomide.

Pure red cell aplasia (PRCA) is a rare disorder characterized by marked erythroid hypoplasia with maturation arrest in the bone marrow. Secondary acquired PRCA may be associated with hematologic disorders. A few case reports have described PRCA associated with multiple myeloma (MM).

Tyrosine kinase inhibitor and rituximab-CHOP treatment for concurrent chronic myeloid leukemia and non-Hodgkin lymphoma: a case report.

Non-Hodgkin lymphoma can occur concurrently with chronic phase-chronic myeloid leukemia (CML) at initial diagnosis. Combination treatment with second-generation tyrosine kinase inhibitors and rituximab-CHOP for patients newly diagnosed with CML and non-Hodgkin lymphoma is effective for both diseases. However, we found that this treatment combination may induce severe myelosuppression.

Transplant-Ineligible Symptomatic but Indolent Multiple Myeloma Shows Better Prognosis with Conventional Agents.

The survival of multiple myeloma patients has improved significantly over the last several decades. However, the median overall survival of these patients remains less than 5 years. In this report, we discuss 4 cases of multiple myeloma patients that showed long survival.

Upfront high-dose chemotherapy combined with autologous stem cell transplantation: Potential survival benefit for patients with high-risk diffuse large B-cell lymphoma.

In patients with diffuse large B-cell lymphoma (DLBCL) classified as high-intermediate risk or high risk using the International Prognosis Index, the efficacy of high-dose chemotherapy combined with upfront autologous stem cell transplantation (HDT/ASCT) remains controversial in the rituximab era. In the present study, 27 patients who had been treated with HDT/ASCT in an upfront setting were retrospectively analyzed, and compared with 77 patients with similar characteristics who had received conventional chemotherapy without HDT/ASCT (the non-upfront setting). The 3-year overall survival and progression-free survival rates in the upfront setting were 88.

Realistic Lenalidomide Dose Adjustment Strategy for Transplant-Ineligible Elderly Patients with Relapsed/Refractory Multiple Myeloma: Japanese Real-World Experience.

Lenalidomide is an immunomodulatory drug administered orally in the treatment of multiple myeloma. Some elderly patients require a reduced lenalidomide dose because of comorbidities and/or adverse events. This study investigated the actual dose of lenalidomide in elderly patients, finding that most received reduced (5-10 mg) doses.

Impact of CRAB Symptoms in Survival of Patients with Symptomatic Myeloma in Novel Agent Era.

The acronym summarizes the most typical clinical manifestations of multiple myeloma, these being hypercalcemia, renal failure, anemia, and bone disease. CRAB can be used to distinguish between active, symptomatic multiple myeloma and monoclonal gammopathy of undermined significance or smoldering myeloma. The distinction is relevant not only for classification and diagnosis but also for therapy.

Delayed HBV reactivation in rituximab-containing chemotherapy: How long should we continue anti-virus prophylaxis or monitoring HBV-DNA?

Reactivation of hepatitis B virus (HBV) infection is a well-recognized and potentially fatal complication in patients treated with chemotherapy for lymphoid malignancies. Although several guidelines recommend antiviral prophylaxis and/or monitoring for HBV-DNA, there is no consensus over what time period these should occur. Clinically, we have encountered delayed reactivation of HBV infections and have reported 12 cases of reactivation in patients.
