Background: Antipsychotic-induced metabolic side effects are major concerns in
psychopharmacology and clinical psychiatry. Their pathogenetic mechanisms are still not elucidated.
Methods: Herein, we ...review the impact of neurotransmitters on metabolic regulation, providing
insights into antipsychotic-induced metabolic side effects.
Results: Antipsychotic drugs seem to interfere with feeding behaviors and energy balance,
processes that control metabolic regulation. Reward and energy balance centers in central nervous
system constitute the central level of metabolic regulation. The peripheral level consists of skeletal
muscles, the liver, the pancreas, the adipose tissue and neuroendocrine connections. Neurotransmitter
receptors have crucial roles in metabolic regulation and they are also targets of antipsychotic drugs.
Interaction of antipsychotics with neurotransmitters could have both protective and harmful effects
on metabolism.
Conclusion: Emerging evidence suggests that antipsychotics have different liabilities to induce
obesity, diabetes and dyslipidemia. However this diversity cannot be explained merely by
drugs’pharmacodynamic profiles, highlighting the need for further research.
Carfilzomib, a proteasome inhibitor, is approved in the United States as a single agent, and in combination with dexamethasone or lenalidomide/dexamethasone (KRd) for relapsed or refractory multiple ...myeloma (MM). Under the single-agent and KRd approvals, carfilzomib is administered as a 10-minute IV infusion on days 1, 2, 8, 9, 15, and 16 of 28-day cycles (20 mg/m2 cycle 1, days 1-2; 27 mg/m2 thereafter). This multicenter, single-arm, phase 1/2 study, Community Harmonized Assessment of Myeloma Patients via an Integrated Oncology Network-1 (CHAMPION-1), evaluated once-weekly carfilzomib with dexamethasone in relapsed, or relapsed and refractory MM (1-3 prior therapies). Patients received carfilzomib (30-minute IV infusion) on days 1, 8, and 15 of 28-day cycles. The phase 1 portion used a 3 + 3 dose-escalation scheme to determine the maximum tolerated dose (MTD) of carfilzomib. During phase 2, patients received carfilzomib on the same schedule at the MTD. Patients received dexamethasone (40 mg) on days 1, 8, 15, and 22; dexamethasone was omitted on day 22 for cycles 9+. A total of 116 patients were enrolled. The MTD was 70 mg/m2, and 104 patients (phase 1/2) received carfilzomib 70 mg/m2. At 70 mg/m2, the median number of prior regimens was 1; and 52% were bortezomib-refractory. At 70 mg/m2, the most common grade ≥3 adverse events were fatigue (11%) and hypertension (7%). Overall response rate at 70 mg/m2 was 77%. Median progression-free survival was 12.6 months. These findings merit additional evaluation of the once-weekly dosing regimen. This trial was registered at www.clinicaltrials.gov as #NCT01677858.
•The CHAMPION-1 study is the first clinical trial to investigate carfilzomib on a once-weekly dosing schedule with dexamethasone.•Once-weekly carfilzomib (30-minute infusion; 20 and 70 mg/m2) with dexamethasone is feasible and effective in relapsed/refractory MM.
This study presents follow-up of a prior study of patients with chronic symptomatic oral chronic graft-versus-host-disease (cGVHD) managed with photobiomodulation therapy (PBM therapy for 1 month. ...Here, we report long-term follow-up of a series of patients where PBM therapy in patients with oral cGVHD for maintenance follows the initial period of PBM therapy for continuing management.
Patients and methods
We report continuing follow-up of 7 cases of oral cGVHD that were treated with PBM therapy. PBM therapy was continued in these patients with the goal of determining the best management schedule of PBM to maintain or improve control of each patient’s symptoms and signs of oral cGVHD.
Results
Oral sensitivity and mucosal changes of cGVHD were controlled with a continuing schedule of PBM therapy of up to 6–8-week treatment intervals in patients with continuing GVHD. These findings suggest that PBM therapy represents an additional approach for continuing management of oral cGVHD and that the frequency of treatment should be individualized for each patient to provide best control of oral findings. In one case weekly PBM treatment was continued, while in others, management on a monthly or bimonthly basis was associated with control of the oral condition. PBM may be individualized and provided based upon best control of the symptoms and signs of oral GVHD.
Chimeric antigen receptor T cells (CAR T cells) have resulted in dramatic treatment responses for patients with hematologic malignancies, resulting in improved survival for patients with intractable ...disease. The first patient treated with CD19 directed CAR T cell therapy had chronic lymphocytic leukemia (CLL) and achieved a complete remission. Subsequent clinical trials have focused largely on patients with other B-cell hematologic malignancies, owing to the fact that CAR T cell therapy for patients with CLL has met with challenges. More recent clinical trials have demonstrated CAR T cell therapy can be well tolerated and effective for patients with CLL, making it a potential treatment option for patients with this disease. In this article we review the background on CAR T cells for the treatment of patients with CLL, focusing on the unique obstacles that patients with CLL present for the development of adoptive T cell therapy, and the novel approaches currently under development to overcome these hurdles.
...we have translated the summary of the comprehensive recommendations into 22 languages (Arabic, Bulgarian, Catalan, Chinese, Croatian, Czech, Dutch, English, French, German, Greek, Hungarian, ...Italian, Japanese, Norwegian, Polish, Portuguese, Romanian, Serbian, Slovenian, Spanish, and Swedish). Building trust between physicians and patients to enhance patients' confidence in medical staff decisions and improve their compliance with medical advice is important, and is the fifth area of recommendation (appendix p 13). ...the sixth area of recommendation concerns the procedures at cancer centres (appendix p 16).
Chimeric antigen receptor T-cell (CAR T-cell) therapy has revolutionized the treatment of relapsed/refractory (R/R) large B-cell lymphoma (LBCL). We describe the real-world baseline characteristics, ...efficacy, safety, and post-relapse outcomes of adult patients with R/R LBCL who received CAR T-cell therapy at the University of California San Diego. A total of 66 patients with LBCL were treated with tisagenlecleucel or axicabtagene ciloleucel. The median age was 59.5, and 21% were over 70 years old. Additionally, 20% of the patients had an Eastern Cooperative Oncology Group (ECOG) performance score of ≥2. Cytokine release syndrome incidence was 88%; immune effector cell-associated neurotoxicity syndrome incidence was 56%. All-grade infection occurred in 48% of patients and in 79% of patients > 70 years old. Complete response (CR) was achieved in 53% and partial response in 14%. Median progression-free survival (PFS) was 10.3 months; median overall survival (OS) was 28.4 months. Patients who relapsed post-CAR T-cell therapy had poor outcomes, with a median OS2 of 4.8 months. Upon multivariate analysis, both ECOG (HR 2.65, 95% CI: 1.30–5.41; p = 0.007) and ≥2 sites of extranodal involvement (HR 2.22, 95% CI: 1.15–4.31; p = 0.018) were significant predictors of PFS. Twenty-six patients were R/R to CAR T-cell therapy; six patients were in remission at the time of data cut off, one of whom received allogeneic transplant. Overall, older patients can safely undergo CAR T-cell therapy, despite the increased risk of all-grade infection. In our cohort, ECOG performance score and ≥2 sites of extranodal disease are significant predictors of PFS.
Cellular quiescence is a state characterized by decreased cell size and metabolic activity. Quiescence acts to reduce the resources, energy and space. Quiescence might also protect cells from ...accumulating metabolic damage that could result in malignancy. Recent studies have shown that cell quiescence is an actively maintained rather than a default state in the absence of signals. Quiescence factors represent potential tumor suppressor genes because alterations in their expression or function contribute to progression of malignancies. There is growing evidence that quiescence is under active transcriptional control. The regulation of cell proliferation involves dozens of extracellular signals and intracellular factors of various types. In the present review we will focus on the role of Tob, a member of the APRO family members in regulating cellular quiescence and inhibition of cellular proliferation.
Purpose
Oral mucormycosis is a rare and high risk of infection in patients following hematopoietic cell transplantation few cases in the literature. We review the literature and present an additional ...case to emphasize the subtle changes that resulted in positive outcome when diagnosed and managed in a comprehensive transplant team.
Results
A patient was diagnosed with gingival mucormycosis on day +25 following a hematopoietic stem cell transplant for lymphoblastic transformation of chronic myeloid leukemia. The patient was diagnosed with minor and nonspecific symptoms and was successfully treated with local dental extraction, a short course of liposomal amphotericin B and 4 months of oral posaconazole.
Conclusions
The good outcome of this case highlights the subtle clinical changes that present early in mucormycosis and the importance of early detection and treatment of post-transplant oral infections by an experienced multidisciplinary team.
Background Brexucabtagene autoleucel (brexu-cel) is an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved in the USA for adults with relapsed or refractory (R/R) B-cell ...acute lymphoblastic leukemia (B-ALL) and in the European Union for patients ≥26 years with R/R B-ALL. After 2 years of follow-up in ZUMA-3, the overall complete remission (CR) rate (CR+CR with incomplete hematological recovery (CRi)) was 73%, and the median overall survival (OS) was 25.4 months in 78 Phase 1 and 2 patients with R/R B-ALL who received the pivotal dose of brexu-cel. Outcomes by prior therapies and subsequent allogeneic stem cell transplantation (alloSCT) are reported. Methods Eligible adults had R/R B-ALL and received one infusion of brexu-cel (1×10⁶ CAR T cells/kg) following conditioning chemotherapy. The primary endpoint was the CR/CRi rate per central review. Post hoc subgroup analyses were exploratory with descriptive statistics provided. Results Phase 1 and 2 patients (N=78) were included with median follow-up of 29.7 months (range, 20.7–58.3). High CR/CRi rates were observed across all prior therapy subgroups examined: 1 prior line of therapy (87%, n=15) and ≥2 prior lines (70%, n=63); prior blinatumomab (63%, n=38) and no prior blinatumomab (83%, n=40); prior inotuzumab (59%, n=17) and no prior inotuzumab (77%, n=61); and prior alloSCT (76%, n=29) and no prior alloSCT (71%, n=49). The frequency of Grade ≥3 cytokine release syndrome, neurological events, and treatment-related Grade 5 adverse events were largely similar among prior therapy subgroups. Median duration of remission (DOR) in responders with (n=14) and without (n=43) subsequent alloSCT was 44.2 (95% CI, 8.1 to not estimable (NE)) and 18.6 months (95% CI, 9.4 to NE); median OS was 47.0 months (95% CI, 10.2 to NE) and not reached (95% CI, 23.2 to NE), respectively. Median DOR and OS were not reached in responders without prior or subsequent alloSCT (n=22). Conclusions In ZUMA-3, adults with R/R B-ALL benefited from brexu-cel, regardless of prior therapies and subsequent alloSCT status, though survival appeared better in patients without certain prior therapies and in earlier lines of therapy. Additional studies are needed to determine the impact prior therapies and subsequent alloSCT have on outcomes of patients who receive brexu-cel.
