Cladribine tablets, a purine analogue antimetabolite, offer a unique treatment regimen, involving short courses at the start of the first and second year, with no further treatment needed in years 3 and 4. However, comprehensive evidence regarding patient outcomes beyond the initial 24 months of cladribine treatment is limited. This retrospective, multicenter study enrolled 204 patients with multiple sclerosis who had completed the 2-year course of cladribine treatment. The primary outcomes were therapeutic choices and clinical disease activity assessed by annualized relapse rate after the 2-year treatment course. A total of 204 patients were enrolled; most patients (75.4%) did not initiate new treatments in the 12 months postcladribine. The study found a significant reduction in annualized relapse rate at the 12-month follow-up after cladribine completion compared to the year prior to starting therapy (0.07 ± 0.25 vs. 0.82 ± 0.80, p < 0.001). Furthermore, patients with relapses during cladribine treatment were more likely to start new therapies, whereas older patients were less likely. The safety profile of cladribine was favorable, with lymphopenia being the primary registered adverse event. This study provides insights into therapeutic choices and disease activity following cladribine treatment. It highlights cladribine's effectiveness in reducing relapse rates and disability progression, reaffirming its favorable safety profile. Real-world data, aligned with previous reports, draw attention to ocrelizumab and natalizumab as common choices after cladribine. However, larger, prospective studies for validation and a more comprehensive understanding of cladribine's long-term impact are necessary.

Familial hypercholesterolemia is a genetically determined disease characterized by elevated plasma total and LDL cholesterol levels from the very first years of life, leading to early atherosclerosis. Nutritional intervention is the first-line treatment, complemented with nutraceuticals and drug therapy when necessary. Nutraceuticals with a lipid-lowering effect have been extensively studied in the past few decades, and have been recently included in international guidelines as a complement to nutritional and pharmacological treatment in subjects with dyslipidemia. In this review, we explore current nutritional interventions for dyslipidemia in childhood, with a specific focus on the main nutraceuticals studied for treating severe dyslipidemia in pediatric patients. Additionally, we briefly describe their primary mechanisms of action and highlight the advantages and risks associated with the use of lipid-lowering nutraceuticals in childhood.

Implantable hearing devices represent a modern and innovative solution for hearing restoration. Over the years, these high-tech devices have increasingly evolved but their use in clinical practice is not universally agreed in the scientific literature. Congresses, meetings, conferences, and consensus statements to achieve international agreement have been made. This work follows this line and aims to answer unsolved questions regarding examinations, selection criteria and surgery for implantable hearing devices. A Consensus Working Group was established by the Italian Society of Otorhinolaryngology. A method group performed a systematic review for each single question to identify the current best evidence on the topic and to guide a multidisciplinary panel in developing the statements. Twenty-nine consensus statements were approved by the Italian Society of Otorhinolaryngology. These were associated with 4 key area subtopics regarding pre-operative tests, otological, audiological and surgical indications. This consensus can be considered a further step forward to establish realistic guidelines on the debated topic of implantable hearing devices.

Introduction |Shellfish allergy is an important cause of food allergies worldwide. Both in vivo and in vitro diagnostics failure nowadays is caused by the poor quality of the extracts associated with the scarce availability of allergenic molecules in the market. It is known that not all patients with shellfish allergies experience adverse reactions to mollusks. It is still unclear how to detect and diagnose correctly these patients. Aim |To investigate the features of shrimp-allergic patients either reactive or tolerant to mollusks, with the currently available diagnostic methods. Methods| Nineteen centers, scattered throughout Italy, participated in the study, enrolling patients allergic to shrimp with or without associated reactions to mollusks. Patients underwent skin tests using commercial extracts or fresh raw and cooked foods, and IgE reactivity to currently available allergenic extracts and molecules was measured in vitro. Results| Two hundred and forty-seven individuals with a history of adverse reaction to crustaceans participated in the study. Only 47.8% of them reacted after cephalopod or bivalve ingestion. None of the tests used, either in vivo or in vitro, was able to detect all selected patients. Accordingly, a great heterogeneity of results was observed with an agreement between in vivo and in vitro tests ranging between 52% and 62% of cases. Skin tests were able to identify the cephalopod and bivalve reactors (p &lt;0.001), also using fresh cooked or raw food (p &lt;0.001). The reactivity profile of mollusk reactors was dominated by Pen m 1, over Pen m 2 and Pen m 4 compared to the tolerant subjects, but 33% of patients allergic to shellfish were not detected by any of the available molecules. A higher frequency of shrimp hypersensitivity was recorded in northern Italy, while mollusk reactivity was more frequent in the center-south. Conclusion |The current diagnostic methods are inadequate to predict the cross-reactivity between crustaceans and mollusks. The detection of mollusks hypersensitivity must still rely on skin tests with fresh material. There is no need to exclude mollusks from shrimp allergic patients’ diet unless clinical history, the available diagnostic instruments, and/or tolerance tests support such a decision. Primary sensitization to mollusks seems possible.

We evaluated 58 patients with relapsed or refractory (r/r) acute B-lymphoblastic leukemia (B-ALL; median age 42.5 years; range, 16-69 years), treated with inotuzumab ozogamicin (INO) between 2016-2022 and who received an allogeneic hematopoietic stem cell transplantation (allo-HCT) consecutively. Forty-seven (81%) of the 58 patients were heavily pretreated receiving intensive chemotherapy +/- tyrosine kinase inhibitor, blinatumomab in 24 (41%) and allo-HCT at first-line in 11 (19%) patients. Complete remission rate prior to allo-HCT was 84%. Median follow-up was 30.5 months and median overall survival (OS) measured from start of INO was 11.2 months. One- and 2-year OS rates were 50% (95% confidence interval [CI]: 38.4-56.1) and 36.7% (95% CI: 25.5-52.9), respectively. Sinusoidal obstruction syndrome/venous occlusive disease (SOS/ VOD) after allo-HCT occurred in 17 (29%) patients. Of those, nine (53%) patients died due to SOS/VOD and multi-organ failure. Two had received >2 INO cycles (3 cycles, 5 cycles, N=1, each), all others ≤2 INO cycles prior to allo-HCT. Logistic regression analysis revealed conditioning with double alkylators (P=0.038) and allo-HCT during first-line therapy (P=0.050) as significant risk factors for SOS/VOD and in trend allo-HCT ≤60 days from last INO application (P=0.07), whereas number of INO cycles before allo-HCT and time between last INO application and allo-HCT were not significant. Relapse/progressive disease occurred in 20 (34%) patients. Of those, five (25%) patients are still alive, whereas 15 succumbed of their disease. Treatment with INO seems to be an effective approach with successful bridge-to-transplant. However, risk of SOS/VOD is high, necessitating continuous monitoring and recognition of SOS/VOD risk factors.

A 90-year-old woman presented at our emergency department complaining of dyspnea (sO2 88% on room air, respiratory rate 24/min) and severe (NRS 8/10) burning chest pain. Ten years earlier, she had undergone a bilateral radical mastectomy and radio-chemotherapy for breast cancer. In September 2023, she developed some nodules on her chest skin treated with electrochemotherapy, multiple liver lesions, and a bilateral paraneoplastic pleural effusion.

Introduction: Based on the efficacy of the fixed-duration venetoclax and rituximab combination (VenR) in the setting of relapsed/refractory (R/R) patients with chronic lymphocytic leukemia (CLL), we investigated the efficacy and safety of the front-line VenR regimen in young (≤65 years) and fit patients with CLL and an unfavorable biologic profile in the GIMEMA LLC1518 VERITAS trial. Here, we report the 36-month updated results of this phase II, single-arm, multicenter, front-line study for young patients with CLL carrying an unmutated IGHV profile and/or a TP53 disruption. Methods: Seventy-five CLL patients requiring treatment, according to the International Workshop on CLL (iwCLL) criteria, were enrolled between October 2018 and May 2020. Treatment consisted of the five-week Ven ramp-up, six-monthly courses of the VenR combination, followed by six monthly courses of Ven single agent. Patients received tumor lysis syndrome (TLS) prophylaxis with urate-reducing agents and oral or iv hydration. The primary endpoint of this study was the complete remission (CR) rate assessed at the end of treatment (EOT, month 15) according to the iwCLL criteria. Measurable/minimal residual disease (MRD) was assessed on the peripheral blood (PB) and bone marrow (BM) by ASO-PCR at baseline, EOT and during the follow-up. MRD was categorized as undetectable (uMRD) with a cut-off of &amp;lt;1 cell in 10,000 leukocytes. Results: The median age of patients was 54 years (range 38-65); 96% had unmutated IGHV, 9 (12%) had TP53 disruption, and 4% showed mutated IGHV with TP53 disruption. At the EOT, the overall response rate (ORR) was 94.7%, with a CR rate of 76%. On an intention-to-treat basis, 52 (69.3%) patients showed a response with uMRD in the PB and 44 (58.7%) in the BM. At 33 months from the EOT, uMRD was maintained by 50% of patients who had achieved an uMRD in the PB and by 57% of those with a prior uMRD in the BM. The 33-month PB MRD-free survival was 50% (Figure 1). In multivariate analysis, factors associated with a significantly shorter MRD-free survival were the presence of an unmutated IGHV associated with a TP53 disruption (HR: 3.43 [95%CI: 1.13-10.4]; p=0.029), Binet B stage (HR: 0.16 [95%CI: 0.06-0.43]; &amp;lt;0.001) or, Binet C stage (HR: 0.19 [95%CI: 0.07-0.52]; p=0.001), while the clinical response, CR, or PR, did not show a significant impact. Three patients have died due to COVID-19. Despite iv hydratation, the administration of anti-uric acids, fatal TLS occurred in a patient who used self-administered fentanyl patches for analgesis purposes during the ramp-up phase. The 36-month OS was 96%. A further lymphoproliferative disorder was diagnosed in 2 patients (follicular lymphoma, 1; large granular cell leukemia, 1) and a second malignancy in 1 (prostate cancer), while no cases of Richter transformation were recorded. No unexpected adverse events were observed during the follow-up. Conclusions: The updated data from the VERITAS trial show that in young and fit patients with adverse genetic characteristics the front-line VenR combination was an effective regimen with high rates of deep responses with uMRD. Furthermore, at 33 months from the EOT, uMRD was maintained in the PB and BM in about half of the patients.

Introduction: The R-BAC regimen is considered among standard first-line treatments for elderly fit patients with mantle cell lymphoma (MCL). We previously reported (RBAC500 trial) a significantly inferior progression-free survival (PFS) for patients with high risk (HR) features, namely blastoid morphology and/or elevated Ki67 proliferative index, as compared to other patients, that were defined as low risk (LR). Indeed, when treated with R-BAC, LR patients had excellent outcome, albeit no maintenance therapy was delivered. Methods: We designed a phase 2 prospective multicenter study, which enrolled patients aged ≥65 years and fit according to the geriatric CGA assessment, or age ≤64 years if not eligible to high-dose chemotherapy plus transplantation. Asymptomatic patients with non-nodal disease were excluded. At presentation patients were allocated by central review as LR or HR, depending on tumor morphology (blastoid versus others), Ki67 expression (≥30% versus others), or presence of TP53 mutation and/or deletion. Patients with any of the three risk factors were classified as HR. Patients with LR disease were treated with 6 cycles of R-BAC (rituximab 375 mg/m2 d 1; bendamustine 70 mg/m2 d 1,2; cytarabine 500 mg/m2 d 1,2,3), while HR patients received abbreviated induction with 4 R-BAC followed by consolidation (4 months, 800 mg/d), and maintenance (20 months, 400 mg/d) with venetoclax. The primary endpoint was 2-years PFS for the HR patients. The sample size was calculated with the one arm non parametric survival analysis (alpha-error 0.05, power 90%), assuming that the addition of venetoclax would improve 2-years PFS from 40% (null hypothesis) to 60%. Tumor response was assessed with Lugano criteria. All patients were analyzed by real-time quantitative PCR at baseline on peripheral blood and bone marrow samples for minimal residual disease (MRD) evaluation, and HR patients were followed up at different time points. Results of this specific analysis will be subject of future reports. This trial was registered at ClinicalTrials.gov Identifier: NCT03567876. Results: Overall, 140 patients from 35 centers of the Fondazione Italiana Linfomi (FIL) were prospectively enrolled between 2018 and 2021. Of them, 54 were HR (39%). Median age was 72 (range 57-79), and 44% had elevated MIPI. LR and HR patients had similar clinical characteristics, but differed for LDH, and MIPI, both being significantly higher in the HR group. Overall, 28 (20%) patients had TP53 mutations, 19 (14%) had TP53 deletions, Ki67 was ≥30% in 34 (24%), and blastoid variant was diagnosed in 13 patients (9%, Figure 1A). Toxicity during R-BAC was in line with previous reports, while most frequent grade &amp;gt;=3 adverse events during venetoclax treatment consisted of neutropenia (21%), followed by skin reactions (10%). Of note, there were 5 deaths due to COVID-19 infection in patients in CR (4 LR, 1 HR). Overall response at the end of R-BAC differed between HR and LR patients (85% vs 99%, p=0.001), as was for complete response (61% vs 91%, p=0.0001). Of the 54 HR patients, 43 (80%) started venetoclax consolidation, 37 (69%) started the maintenance phase, with 26 patients (48%) completing the whole treatment per protocol. Of 10 patients that started Venetoclax in partial remission (PR) or stable disease after R-BAC, 3 converted to CR, 1 maintained PR, while 6 patients progressed during maintenance. After a median follow-up of 34 months, the 2-years PFS for the whole population was 74.9% (95% CI 66-82), and OS was 80% (95% CI 72-85). Patients with HR MCL had 2-years PFS and OS of 58% (95% CI 43-70) and 66% (95% CI 50-77), respectively, which were significantly lower than LR patients (85% and 88%, respectively, p=0.0001 for both, see Figure 1B). Predictors of PFS using Cox regression models adjusted for MIPI were blastoid morphology (Hazard Ratio 3.51), and TP53 mutation (Hazard Ratio 4.17), with Ki67, and TP53 deletions that lost their power in multivariate analysis. Conclusions: The VR-BAC trial represents the first prospective study that stratified upfront patients with MCL to different treatments according to the risk profile. In this trial the null hypothesis (2-years PFS 40%) was rejected in HR patients, suggesting that the addition of venetoclax to R-BAC improves the performance of the induction strategy. These results point to the importance of identifying HR patients since initial diagnosis.

In recent years the management of patients (pts) with chronic lymphocytic leukemia (CLL) has benefited from a deeper knowledge of the mechanisms underlying the disease and from the development of novel therapeutic approaches. That notwithstanding, local and national accessibility to drugs and tests may lead to distinct “real-world” practices in terms of management of pts that are worth of being recorded and compared to understand the degree of reproducibility and applicability of international guidelines. This could also be relevant for the design of future clinical trials, more tailored to the true patient's needs. To this end, within the GIMEMA cooperative study group the observational retrospective and prospective CLL2121 study (NCT04867915) has been designed with the objective of evaluating the diagnosis and management of CLL in all hematological centers in Italy through the assessment of: 1) the methods and the actual diagnostic/prognostic work-up capacity; 2) the algorithms applied to define disease progression and treatment requirements with respect to national and international guidelines; 3) the clinical and biological variables not strictly associated with CLL, but capable of influencing the clinical course and overall survival; 4) the true incidence of some rarer complications associated with CLL. The study consists of a collection of clinico-biological data from all pts with newly diagnosed CLL, small lymphocytic lymphoma (SLL) or CLL-like monoclonal B-cell lymphocytosis (MBL), according to the iwCLL 2018 criteria in Italy. The retrospective part aims at including all cases followed at the participating centers with a diagnosis between January 2010 and September 2021, while the prospective part will include all pts with a documented diagnosis of CLL, SLL or MBL between September 2021 and September 2025. In this pilot analysis of the study, we examined pts' demographics, diagnosis, treatment line and type. Data were collected using the REDCap electronic data capture platform, analyzed using the SAS software v.9.4 and reported as numbers and frequencies. Between 2 November 2021 and 28 June 2023, 3294 eligible pts were enrolled in 75 hematology centers (out of the total of 110 centers who will be activated during the study) across the entire Italian territory. At the time of the present report, 3033 pts had clinical data available for our preliminary analysis. The vast majority of pts registered (N=2599, 85.7%) belonged to the retrospective cohort while only a minority (N=434, 14.3%) to the prospective cohort. Pts had a median age of 68 years ranging from 29 to 97; 60% of pts were males. 2630 pts (86.8%) had a diagnosis of CLL, 187 (6.2%) of SLL and 214 (7.0%) of MBL (2 missing information). Among those with available results 112 pts (12.6%) were TP53 mutated, 526 (45.6%) del(13q) positive, 174 (14.9%) del(11q) positive, 142 (11.9%) del(17p) positive and 226 (20.4%) presented a trisomy 12. The majority of pts (57.6%) were untreated, while 42.4% have been treated. Within the latter subset, 67.3% of pts have received one line of therapy, 21.4% 2 lines of therapy, 11.3% ≥3 lines of therapy. The most common therapeutic regimens were the combination of chemotherapy with an anti-CD20 antibody (39.3%), mainly rituximab, and those based on BTK inhibitors (33.3%), mainly ibrutinib. Chemotherapy alone was used in 12% of pts. Only 5% of pts was treated with the BCL2 inhibitor venetoclax. In the remaining 10% of pts, other approaches were used. This is the initial report of a nation-based real-world data collection aimed at describing the biological and clinical features of pts diagnosed with CLL in virtually all Italian hematology centers starting from 2010. The pattern of treatments highlighted in our preliminary analysis, with a wide use of the watch &amp; wait policy and of chemoimmunotherapy, will help understand how the introduction of novel therapies impacted treatment habits also in light of the timing of the local reimbursement policy. The different time of drug access in Italy, typically delayed after the EU approval, may also have affected the limited use of venetoclax-based treatment. The continuous accrual of pts in this study will allow to obtain a close-to-registry vision of CLL management in Italy over time, in terms of coverage of the entire country but enriched with the granularity of the data and flexibility of the collection typical of a real-world study.
