Nutritional intervention with TGF-beta enriched food for special medical purposes (TGF-FSMP) is associated with a reduction of malnutrition, acute GVHD, pneumonia and may improve overall survival in patients undergoing allogeneic hematopoietic stem transplantation
: Malnutrition in allogeneic stem cell transplant (allo-SCT) is associated with poor outcomes. Supplementation with Foods for Special Medical Purposes may be a valid alternative to enteral nutrition or total parental nutrition to reduce malnutrition in allo-SCT. In this study, 133 patients consecutively allo-transplanted were assessed for nutritional status by Patient- Generated Subjective Global Assessment (PG-SGA) and supplemented with TGF-beta enriched Food for Special Medical Purposes (TGF-FSMP). PG-SGA, gold standard for nutritional assessment in oncologic patients, was assessed at admission and on day 0, +7, +14, +21, and + 28 from transplant and categorized as follows: A = good nutritional status; B = moderate malnutrition; C = severe malnutrition. TGF-FSMP (Modulen-IBD) is currently used in Inflammatory Bowel Diseases (IBD) as primary nutritional support and in this study the dose was calculated according to BMI and total daily energy expenditure (TDEE). The patients assuming ≥50% of the prescribed TGF-FSMP dose were classified in Group A; the patients who received < 50% were included in Group B per protocol. The primary endpoint of the study was the assessment of the malnourished patients in Group A and B at day+28 after transplantation, according to the criteria of PG-SGA C categorization. At day +28 after transplant: i) patients in Group A were significantly less severely malnourished than patients in the Group B (21/76,28% vs 42/53, 79% respectively, OR 2.86 - CI 1.94-4.23 -, p = 0.000); ii) the incidence of severe (MAGIC II-IV) aGVHD and of any grade gastrointestinal (GI) aGVHD was higher in Group B than in Group A, (43% vs 21% p = 0.003) and (34.5% vs 9.2% p = 0.001); iii) Pneumonia was more frequent in the malnourished patients of Group B than in well/moderate nourished patients of Group A (52.7% vs 27.6% p = 0.002). In group A parenteral nutrition was avoided more frequently than in group B (67.5% vs 33.3% p = 0.000) and a median hospital stay of 27 days in comparison to 32 was reported (p = 0.006). The estimated median overall survival (OS) of the population was 33 months in Group A and 25.1 months in group B (p = 0.03). By multivariate and ANN analysis, TGF-FSMP TR < 50% assumption was significantly correlated with malnutrition, severe and GI aGVHD, pneumonia and reduced OS
Sequential monitoring of lymphocyte subsets and of T-and-B cell neogenesis indexes to identify time-varying immunologic profiles in relation to graft-versus-host disease and relapse after allogeneic stem cell transplantation
T and B lymphocyte subsets have been not univocally associated to Graft-versus-host disease (GVHD) and relapse of hematological alignancies after stem cell transplantation (SCT). Their sequential assessment together with B and T cell neogenesis indexes has been not thoroughly analysed in relation to these changing and interrelated immunologic/clinic events yet.
Lymphocyte subsets in peripheral blood (PB) and B and T cell neogenesis indexes were analysed together at different time points in a prospective study of 50 patients. Principal component analysis (PCA) was used as first step of multivariate analysis to address issues related to a high number of variables versus a relatively low number of patients. Multivariate analysis was completed by Fine-Gray proportional hazard regression model. PCA identified 3 clusters of variables (PC1-3), which correlated with acute GVHD: PC1 (pre-SCT: KRECs 656608/ml, unswitched memory B 44%, CD8+TCM cells>4%; HR 1.9, p = 0.01), and PC3 (at aGVHD onset: CD4+TEMRA69%, switched memory CD19+ = 0 cells and KRECs<6614/ml at +90; HR 0.1, p = 0.008). All these immunologic parameters were independent indicators of chronic GVHD and relapse, also considering the possible effect of previous steroid-therapy for acute GVHD. Specific time-varying immunologic profiles were associated to GVHD and relapse. Pre-SCT host immune-microenvironment and changes of B cell homeostasis could influence GVH- and Graft-versus-Tumor reactions. The paradoxical increase of EM Treg in PB of patients with GVHD could be explained by their compartmentalization outside lymphoid tissues, which are of critical relevance for regulation of GVH reactions
Digital PCR improves the quantitation of DMR and the selection of CML candidates to TKIs discontinuation
Treatment-free remission (TFR) by tyrosine kinase inhibitors (TKI) discontinuation in patients with deep molecular response (DMR) is a paramount goal in the current chronic myeloid leukemia (CML) therapeutic strategy. The best DMR level by real-time quantitative PCR (RT-qPCR) for TKI discontinuation is still a matter of debate. To compare the accuracy of digital PCR (dPCR) and RT-qPCR for BCR-ABL1 transcript levels detection, 142 CML patients were monitored for a median time of 24\ua0months. Digital PCR detected BCR-ABL1 transcripts in the RT-qPCR undetectable cases. The dPCR analysis of the samples, grouped by the MR classes, revealed a significant difference between MR4.0 and MR4.5 (P\ua0=\ua00.0104) or MR5.0 (P\ua0=\ua00.0032). The clinical and hematological characteristics of the patients grouped according to DMR classes (MR4.0 vs MR4.5-5.0 ) were superimposable. Conversely, patients with dPCR values <0.468 BCR-ABL1 copies/\ub5L (as we previously described) showed a longer DMR duration (P\ua0=\ua00.0220) and mainly belonged to MR4.5-5.0 (P\ua0=\ua00.0442) classes compared to patients with higher dPCR values. Among the 142 patients, 111 (78%) discontinued the TKI treatment; among the 111 patients, 24 (22%) lost the MR3.0 or MR4.0 . RT-qPCR was not able to discriminate patients with higher risk of MR loss after discontinuation (P\ua0=\ua00.8100). On the contrary, according to dPCR, 12/25 (48%) patients with BCR-ABL1 values 650.468 and 12/86 (14%) patients with BCR-ABL1 values <0.468 lost DMR in this cohort, respectively (P\ua0=\ua00.0003). Treatment-free remission of patients who discontinued TKI with a dPCR <0.468 was significantly higher compared to patients with dPCR\ua0 65\ua00.468 (TFR at 2\ua0years 83% vs 52% P\ua0=\ua00.0017, respectively). In conclusion, dPCR resulted in an improved recognition of stable DMR and of candidates to TKI discontinuation

Prednisone vs high-dose dexamethasone in newly diagnosed adult primary immune thrombocytopenia: a randomized trial
A debate exists regarding which type of corticosteroids (standard-dose prednisone [PDN] or high-dose dexamethasone [HD-DXM]) is the best first-line treatment for adult patients with newly diagnosed untreated primary immune thrombocytopenia (pITP). An ad hoc study compared PDN with HD-DXM in newly diagnosed untreated patients with pITP (aged >= 18 but <= 80 years, platelet count of <= 20 or >20 but <50 x 10(9)/L, and bleeding score of >= 8). Patients were randomised to receive PDN 1 mg/kg per day from days 0 to 28 (Arm A) or HD-DXM 40 mg per day for 4 days, every 14 days, for 3 consecutive courses (Arm B). Fifty-nine of 113 patients (52.2%) were randomized to Arm A and 54 of 113 (47.8%) to Arm B. In evaluable patients, total initial responses (complete response [CR], partial response [PR], minimal response [MR]) were 44 of 56 (78.57%) in Arm A and 46 of 49 (93.88%) in Arm B at days 42 and 46, respectively (P = 0.0284). Total final responses (at day 180 from initial response) were 26 of 43 (60.47%) in Arm A and 23 of 39 (58.97%) in Arm B (P = 0.8907). Total persistent responses (at 12 months from initial response) were 25 of 31 (80.65%) in Arm A and 20 of 36 (55.56%) in Arm B (P = 0.0292). Seven relapses occurred. Median follow-up was 44.4 months. Overall survival was 100% at 48 months, overall disease-free survival was 81.11% at 48 months from day 180. PDN and pulsed HD-DXM were well tolerated; HD-DXM allows effective initial responses but less long lasting than PDN. This trial was registered at www.clinicaltrials.gov as #NCT00657410
Successful CAR-T cell therapy in a refractory MCL patient with bacterial, fungal and COVID-19 infection: a case report
BackgroundThe COVID-19 pandemic has had a significant impact on the management and care of onco-hematological patients, particularly those with lymphoproliferative disorders who are at higher risk for COVID-19 associated bacterial and fungal superinfections.Case presentationWe present the successful treatment of a 44-year-old male patient with refractory mantle cell lymphoma treated with chimeric antigen receptor T (CAR-T) cell therapy, despite concurrent COVID-19 infection. The patient developed grade II cytokine release syndrome, requiring admission to the intensive care unit. The CAR-T cells expanded effectively, and the patient achieved complete metabolic remission. During the treatment course, the patient experienced complications including COVID-19-associated pulmonary aspergillosis and a co-infection with Stenotrophomonas maltophilia and the SARS-CoV-2 omicron variant. Prompt antifungal and antibacterial therapy, along with appropriate COVID-19 treatment, led to the resolution of these infections. Dexamethasone was also administered to reduce inflammation and aid hematologic recovery. Despite the presence of multiple infections, the patient achieved complete remission of lymphoma, highlighting the effectiveness of CAR-T cell therapy in this high-risk patient.ConclusionDespite the challenges posed by concurrent infections, the decision to proceed with CAR-T cell therapy in this patient proved to be successful, resulting in complete remission of lymphoma. Early initiation of supportive therapies and the use of dexamethasone contributed to the resolution of complications. This case underscores the importance of individualized decision-making and the potential benefits of CAR-T cell therapy in similar high-risk patients
Triceps Surae Muscle Characteristics in Spastic Hemiparetic Stroke Survivors Treated with Botulinum Toxin Type A: Clinical Implications from Ultrasonographic Evaluation
Equinovarus foot is one of the most commonly spasticity related conditions in stroke survivors, leading to an impaired gait and poor functional performances. Notably, spastic muscles undergo a dynamic evolution following typical pathophysiological patterns. Botulinum Neurotoxin Type A (BoNT-A) is the gold standard for focal spasticity treatment, and ultrasound (US) imaging is widely recommended to guide injections and monitor muscle evolution. The role of BoNT-A in influencing muscle fibroadipose degeneration is still unclear. In this study, we analyzed medial gastrocnemius (MG) and soleus (SOL) US characteristics (cross-sectional area, muscle thickness, pennation angle, and mean echo intensity) in 53 patients. MG and SOL alterations, compared to the unaffected side, depend on the spasticity only and not on the BoNT-A treatment. In functionally preserved patients (functional ambulation classification, FAC > 3; modified Ashworth scale, MAS ≤ 2), the ultrasonographic changes of MG compared to ipsilateral SOL observed in the paretic limb alone seems to be due to histological, anatomical, pathophysiological, and biomechanical differences between the two muscles. In subjects with poor walking capability and more severe spasticity, such ipsilateral difference was found in both calves. In conclusion, BoNT-A does not seem to influence muscle degeneration. Similar muscles undergo different evolution depending on the grade of walking deficit and spasticity
Efficacy of rehabilitation interventions on functioning in patients with hemophilic arthropathy: A systematic review with meta-analysis
Background: Hemophilic arthropathy is a detrimental condition that crucially affects functional outcomes in hemophilic patients. In recent years, due to the advances in systemic therapies, growing attention has been raised in the rehabilitation field in order to improve functional outcomes of hemophilic patients. However, the optimal rehabilitation modalities in these patients are far from being fully characterized. Objective: The present study aimed to assess the effects of different rehabilitation interventions on physical functioning and health-related quality of life of hemophilic arthropathic patients. Methods: The review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Five databases were systematically searched for randomized controlled trials (RCTs) published until June 22nd, 2023. The selection criteria included adult patients with hemophilia A and B receiving rehabilitation interventions. The outcomes were muscle strength, physical function, pain intensity, physical performance, and health-related quality of life. Results: Out of 1,743 identified records, 17 studies were included in the qualitative synthesis. Rehabilitation interventions were categorized into exercise intervention, fascial therapy, and multimodal intervention. The findings suggested positive outcomes in terms of muscle modifications, range of motion improvements, joint health enhancements, pain intensity reduction, and quality of life improvements. More in detail, meta-analyses showed significant improvements in pain intensity [ES: -1.10 cm (-1.37, -0.82), p< 0.00001], joint health [ES: -1.10 (-1.38, -0.82), p< 0.00001], In accordance, exercise interventions showed significant benefits in terms of joint health [ES: -2.54 (-3.25, -1.83), p< 0.00001)] and quality of life [ES: 1.17 (0.48, 1.86), p< 0.0000)]. Conclusion: Rehabilitation interventions have a positive impact on functional outcomes and health-related quality of life of hemophilic arthropathic patients. Further studies are needed to better elucidate the role of a comprehensive intervention combining different rehabilitation approaches to treat hemophilic arthropathy
Effects of Ultrasound-Guided Injection Combined with a Targeted Therapeutic Exercise in Breast Cancer Women with Subacromial Pain Syndrome: A Randomized Clinical Study
In this randomized controlled study, we aimed to assess the effects of US-guided injections of the subacromial bursa followed by a personalized rehabilitation program for breast cancer (BC) survivors. We assessed patients with subacromial pain syndrome without tendon lesions and with a history of post-surgical non-metastatic BC. Thirty-seven patients were enrolled and randomly assigned 1:1 to receive US-guided corticosteroid injections combined with a personalized rehabilitation program (Group A; n: 19) or US-guided corticosteroid injections alone (Group B; n: 18). The primary outcome was pain relief, assessed using a numerical pain rating scale (NPRS). The secondary outcomes were muscle strength, shoulder function, and quality of life. No major or minor late effects were reported after the multidisciplinary intervention. Statistically significant within-group differences were found in terms of NPRS (p ≤ 0.05) in both groups. No significant between-group differences were reported after one week. However, the between-group analysis showed significant differences (p ≤ 0.05) after three months of follow-up in terms of pain intensity, muscle strength, shoulder function, and quality of life. Our findings suggested positive effects of a multidisciplinary approach including US-guided corticosteroid injections combined with a personalized rehabilitation program in improving pain intensity and quality of life of BC survivors with subacromial pain syndrome
