    Abstract The patient is a 34-year-old HIV antibody-negative female with normal immunocompetence. The patient was referred to the hospital of the current study due to diarrhea and abdominal pain, which developed in May 2014. On conducting computed tomography (CT), remarkable wall thickening was noted in the terminal ilium over the ascending colon, suggesting a malignant tumor. However, making a definite diagnosis by lower gastrointestinal endoscopic biopsy and left hemicolectomy was not possible. The dense proliferation of plasma cell-like cells and plasmablasts was noted; CD20, CD19, CD79a, CD3, CD4, and Epstein-Barr virus-encoded miRNAs (EBER) were negative and CD138 was positive on immunostaining. Based on the aforementioned data, the patient was diagnosed with plasmablastic lymphoma (PBL). High-dose chemotherapy combined with autologous peripheral blood stem cell transplantation (PBSCT) was performed in the first remission period after the completion of four cycles of hyper CVAD/MTX-AraC alternating therapy. Remission was confirmed by FDG-PET/CT 3 months after autologous PBSCT. No signs of recurrence have been observed in 6 years after the transplantation. Although no standard treatment for PBL has been established, autologous peripheral blood stem cell transplantation combined with high-dose chemotherapy during the first remission period may be a beneficial treatment option.

    Abstract Introduction: Within the realm of chemogenetics, a particular form of agonists targeting designer receptors exclusively activated by designer drugs (DREADDs) has emerged. Deschloroclozapine (DCZ), a recently introduced DREADDs agonist, demonstrates remarkable potency in activating targeted neurons at a lower dosage compared to clozapine-N-oxide (CNO).
    Methods: We conducted a comparative analysis of the effects of subcutaneously administered CNO (1 mg/kg) and DCZ (0.1 mg/kg) in our transgenic rats expressing hM3Dq and mCherry exclusively in oxytocin (OXT) neurons.
    Results and discussion: Notably, DCZ exhibited a swift and robust elevation of serum OXT, surpassing the effects of CNO, with a significant increase in the area under the curve (AUC) up to 3 hours post-administration. Comprehensive assessment of brain neuronal activity, using Fos as an indicator, revealed comparable effects between CNO and DCZ. Additionally, in a neuropathic pain model, both CNO and DCZ increased the mechanical nociceptive and thermal thresholds; however, the DCZ-treated group exhibited a significantly accelerated onset of the effects, aligning harmoniously with the observed alterations in serum OXT concentration following DCZ administration. These findings emphasize the remarkable efficacy of DCZ in rats, suggesting its equivalent or potentially superior performance to CNO at considerably lower dosages, thus positioning it as a promising contender among DREADDs agonists.

    Abstract The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rapidly spreading across the world. We encountered two patients with COVID-19 who underwent treatment for acute leukemia at initial diagnosis. Both the patients received conventional induction therapy without the exacerbation of COVID-19. Although the impact of SARS-CoV-2 on the treatment of leukemia is unclear, our treatment experience suggests that there is no major contraindication to standard chemotherapy for acute leukemia in patients with COVID-19. As COVID-19 continues to be a threat worldwide, further evaluations of large cohorts are needed for future treatment decisions for acute leukemia with COVID-19.

    Abstract We had two cases of trisomy 8-positive myelodysplastic syndrome (MDS) with incomplete Behçet's disease (BD) in which the remissions of both diseases were maintained by allogeneic stem cell transplantation (allo-SCT). Among MDS with BD patients, sometimes it is difficult to control the symptoms of BD with standard therapies such as corticosteroids and tumor necrosis factor (TNF) inhibitors. Although there should be careful consideration regarding indications for transplantation, our two cases, in which refractory BD was completely controlled by allo-SCT, suggest that allo-SCT can be one of the treatment options for higher-risk MDS with BD patients.
