RESUMEN
Relapsed or refractory (r/r) Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) still represent an unmet clinical need despite the new immune therapies available for these patients. We report the case of a Ph + ALL relapsed one year after allogeneic stem cell transplant. After one DLI was started CAR-T program with brexucabtageneautoleucel, using as bridging treatment ponatinib, vincristine and prednisone. Brexu-cel infusion was performed in 2023, without CRS or ICANS onset. One month after Brexu-cel infusion BM aspirate and CT-PET showed recovery of full donor chimerism, MRD negativity and complete metabolic remission. Subsequently was started maintenance with ponatinib: at last follow-up, the patient persisted in leukemia-free status. CAR-T cells represent the most powerful treatment for r/r Ph + ALL but there is no consensus about the optimal bridging strategy and also regarding the management algorithm during "post CAR-T phase". Here, we report the efficacy of ponatinib as a bridge to anti-CD19 CAR-T cell therapy and as post CAR-T maintenance. Our experience suggests that a preserving approach with TKI associated to low-dose chemotherapy can be the optimal bridging therapy prior to CAR-T and that an "MRD-guided" and "TKI-based" maintenance strategy can represent the best choice for Ph + ALL which satisfactorily responds to CAR-T.

Multiple myeloma (MM) is the main indication for autologous stem cell transplantation (ASCT). Novel supportive therapies (e.g., granulocyte colony-stimulating factor) have significantly improved post-ASCT-related mortality; however, data on biosimilar pegfilgrastim-bmez (BIO/PEG) in this setting is lacking. This prospective cohort study compared Italian patients with MM who received BIO/PEG post-ASCT with data collected retrospectively from historical control groups from the same center who received either filgrastim-sndz (BIO/G-CSF) or pegfilgrastim (PEG; originator). The primary endpoint was time to neutrophil engraftment (three consecutive days with an absolute neutrophil count ≥ 0.5 × 109/L). Secondary endpoints included incidence and duration of febrile neutropenia (FN). Of the 231 patients included, 73 were treated with PEG, 102 with BIO/G-CSF, and 56 with BIO/PEG. Median age was 60 years and 57.1% were male. Neutrophil engraftment was reached after a median of 10 days in the BIO/PEG and PEG groups and 11 days in the BIO/G-CSF group. Among patients who achieved neutrophil engraftment earlier than this (i.e., day 9), 58% (29/50) were on PEG; of those who achieved it later (i.e., day 11), 80.8% (59/73) were on BIO/G-CSF. FN incidence was higher with BIO/G-CSF (61.4%) versus PEG (52.1%) or BIO/PEG (37.5%) (p = 0.02 among groups). Patients on BIO/PEG had less frequent grade 2-3 diarrhea (5.5%) compared with BIO/G-CSF (22.5%) or PEG (21.9%); grade 2-3 mucositis was most frequent in the BIO/G-CSF group. In conclusion, pegfilgrastim and its biosimilar displayed an advantageous efficacy and safety profile compared with biosimilar filgrastim in patients with MM post-ASCT.

PURPOSE: CAR-T programs will burden increasingly on healthcare systems, since the implementation of these therapies involves: multidisciplinary team collaboration, post-infusion hospitalization with risk of life-threatening toxicities, frequent in hospital visits and prolonged follow-up which heavily influence patients' quality of life. In this review we propose an innovative, telehealth-based, model for monitoring CAR-T patients: this method was used for managing a case of COVID-19 infection occurred two weeks after CAR-T cell infusion. METHODS: Several benefits for management of all these aspects of CAR-T programs could be made using telemedicine: for example, telemedicine real-time clinical monitoring could reduce the COVID-19 contagion risks for CAR-T patients. RESULTS: Our experience confirmed feasibility and utility of this approach in a real-life case. We believe that use of telemedicine for CAR-T patients could improve: the logistics of toxicity monitoring (frequent vital sign checks and neurologic assessments), the multidisciplinary team communication (patient selection, specialists consulting, coordination with pharmacists, etc.), the decrease in hospitalization time and the reduction of ambulatory visits. CONCLUSIONS: This approach will be fundamental for future CAR-T cell program development, enhancing patients' quality of life and cost-effectiveness for healthcare systems.

Apremilast is an oral selective phosphodiesterase-4 inhibitor developed recently for psoriasis treatment. The aim of this study is to assess the real-life outcomes of use of apremilast in patients with psoriasis in everyday clinical practice. A total of 159 adult patients (90 males) with plaque psoriasis were included in the study. Fifty of the patients (31%) had psoriatic arthritis. All patients started apremilast at the time of enrolment. There was a marked improvement in Psoriasis Area and Severity Index, body surface area and Dermatology Life Quality Index scores across the follow-up period (12 months). The improvements in these scores were also consistent when the patients were stratified according to increasing body mass index. Only 10.6% of the patients discontinued apremilast, because of no response. In conclusion, apremilast is an effective and safe treatment in patients with psoriasis, and its effect is not influenced by body mass index.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a clinically challenging modality for the treatment of many hematologic diseases such as leukemia, lymphoma, and myeloma. Graft-versus-host disease (GVHD) is a common complication after allo-HSCT and remains a major cause of morbidity and mortality, limiting the success of a potentially curative transplant. Several microRNAs (miRNAs) have recently been shown to impact the biology of GVHD. They are molecular regulators involved in numerous processes during T-cell development, homeostasis, and activation, and contribute to the pathological function of T-cells during GvHD. Here, we review the key role of miRNAs contributing to the GvHD; their detection might be an interesting possibility in the early diagnosis and monitoring of disease.

INTRODUCTION: Chimeric Antigen Receptor ;(CAR) T cells therapies have become part of the standard of care for patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). The weakness of CAR-T therapies is that there are no comparative clinical trials, although many publications based on real-life data have confirmed the results obtained in pivotal studies. After several years of the commercialization of CAR-T, some points still need to be fully clarified. Healthcare professionals have questions about identifying patients who may benefit from therapy. There are aspects inherent in the accessibility of care related to improved relationships between CAR-T-delivering and referral centers. AREAS COVERED: Open questions are inherent in the salvage and bridge therapy, predictive criteria for response and persistence of CAR-T after infusion. Managing toxicities remain a top priority and one of the points on which further knowledge is needed. EXPERT OPINION: This review aims to describe the current landscape of CAR-T cells in DLBCL, outline their outcomes and toxicities, and explain the outstanding questions that remain to be addressed.

Background: The anti-inflammatory drug, thalidomide, is often administered off-label especially in dermatology patients with diseases refractory to different medications. The drug's mechanism of action is not well understood but clinical evidence suggests an immunomodulatory function. Although this drug is a useful tool for several dermatoses, there are associations between its use and neurotoxic and teratogenic side effects. Consequently, it is reserved only for severe and refractory cases. Methods: Herein, we present a review about thalidomide focusing on its application in dermatology, particularly on discoid lupus erythematosus (DLE) treatment. We analyzed four cases of people who had a regression of DLE with a dosage of 50 mg thalidomide. Patients were followed to determine the conditions treated with thalidomide, dosage, efficacy, duration of treatment, side effects, adverse events and follow-up. A low dose of 50 mg/day induced a notable and rapid improvement within 1-2 months of treatment and no side effects have been reported so far. Results: We report four cases of DLE treated previously with the most common immunomodulatory agents with no results and finally successfully treated with thalidomide. In all four patients, despite a low dose of 50 mg/day, a notable and rapid improvement was obtained within a few months of treatment with no side effects. Conclusions: Notwithstanding the small cohort size, our experience confirms the efficacy of thalidomide for the treatment of DLE.
