In this follow-up study, we investigated the long-term effects of MBI on TFS after the intervention ceased.Methods: 60 participants from the initial study (34 who received intervention vs. 26 controls) were followed for an additional period of 20 months. TFS was assessed from the end of the intervention to the initiation of CLL therapy or death, using Kaplan-Meier analysis and the log-rank test.Results: By the end of the follow-up, 9 participants who previously received MBI and 6 controls initiated CLL treatment. No significant difference in TFS was found between the groups (log-rank test p = 0.65).Conclusion: While MBI provided a clear advantage as long as it continued, our follow-up analysis suggests this effect diminishes after the intervention ends. Continuous or repeated MBI may be necessary for sustained improvements in TFS.","PeriodicalId":6981,"journal":{"name":"Acta Haematologica","volume":" ","pages":"1-6"},"PeriodicalIF":1.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, bibliometric research in this area is still sparse. Through bibliometric analysis, we aimed to visualize the research hot spots and trends of immunotherapy in DLBCL disease to help understand the future development of basic and clinical research.Methods: The Web of Science Core Collection database was searched for articles and reviews related to the immunotherapy of DLBCL from 2004 to 2024. VOSviewers, CiteSpace, and the R package \"bibliometrix\" were used to conduct the bibliometric analysis.Results: A total of 662 articles were included. The number of immunotherapy treatments in DLBCL increased year by year. The publications came from 55 countries, led by the United States and the People's Republic of China, and 1,349 institutions, with the leading research institutions being The University of Texas MD Anderson Cancer Center and Memorial Sloan Kettering Cancer Center. Leukemia & lymphoma is the journal with the most research, and Blood is the journal with the most co-citations. We identified 4833 authors, among which Young and Ken H had the most significant articles, while Neelapu SS had the largest number of co-citations. After analysis, the most common keyword is CAR T.

The approved regimen requires an initial dose of 100 μg or 50 μg if transitioning from hydroxyurea (HU) and up-titrations of 50 μg every two weeks to 500 μg maximumly. The time to achieve the plateau dose takes approximately 20 weeks. This study compares the approved regimen with a higher initial dose and accelerated dose titration (HIDAT) regimen. Methods and Conclusion: ECLIPSE-PV is a randomized, open-label, multicenter trial in patients with PV in the US and Canada. Patients received ropeg either per the approved dosing schema, or HIDAT regimen, i.e., 250 μg on Day 0, 350 μg at Week 2, and 500 μg from Week 4 thereafter if tolerable. The primary endpoint is complete hematologic response (CHR) rate at Week 24. CHR is defined as hematocrit <45%, white blood cells <10×109/L, platelets ≤400×109/L without phlebotomy in the previous 12 weeks. Secondary endpoints include molecular response, safety and tolerability, and quality of life. A total of 111 patients were randomized and the last patient was enrolled on June 21, 2024. As of November 12, 2024, the discontinuation rate was 14.4% and 16 patients (14.4%) completed the study. The study is expected to be completed in the summer of 2025. This is the first prospective trial comparing two dosing regimens of ropeg.

The National Comprehensive Cancer Network (NCCN) recommends screening patients for distress by a self-reported scale (0-10) and to refer those with scores ≥ 4 to supportive services (SS). Little is known about the prevalence of distress and healthcare utilization in classical Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs): polycythemia vera (PV), essential thrombocythemia (ET), myelofibrosis (MF). METHODS We retrospectively identified MPN patients at our center to measure the proportions of patients with distress ≥ 4 evaluated by a SS [chaplaincy, integrative oncology, palliative medicine, psychiatry, psychology, and social work (SW)] or had acute care utilization (ACU; ≥ 1 ED visit or hospitalization) within six months of electronic distress screening (EDS). We also obtained sociodemographic, disease characteristics, and symptom score data to stratify variables associated with distress. RESULTS Among 141 patients (44 PV, 49 ET, 48 MF), the median age was 63 years (range, 25-89). Most patients identified as female (62%), White (77%), and completed EDS within three months of diagnosis (55%). Of 75/141 (53%) who reported distress ≥ 4, only 25/75 (33%) were evaluated by SS, and 23/75 (31%) had ACU within six months of EDS. Patients with distress ≥ 4 evaluated by SS had significantly higher ACU (48% vs. 14%; p=0.009). Distress was associated with higher symptom scores and more ED visits but not gender, race, ethnicity, diagnosis, relationship status, or insurance.

This study aimed to explore key ferroptosis-related genes (FRGs) in AA using bulk and single-cell RNA sequencing (scRNA-seq) data.Methods: scRNA-seq and bulk RNA-seq data, along with FRG lists, were obtained from public databases. Differentially expressed FRGs (DEFRGs) between AA and control samples were identified, followed by functional enrichment and protein-protein interaction analyses. Single-cell analyses were conducted to reveal main cell types in samples and DEFRGs activity in each cell was assessed. Moreover, DEGs between AA and control samples at the cellular level were explored, followed by integration with DEFRGs to determine common key genes. KEGG pathway analysis of these genes was performed at the cellular level. Immune infiltration analysis was used to evaluate the relationship between key genes and immune cells.Results: A total of 38 DEFRGs were identified, enriched in pathways such as the intrinsic apoptotic signalling pathway. scRNA-seq analysis identified seven cell types, with elevated DEFRGs activity in platelets and stromal cells. Key genes DDIT4 and NCF2, identified through integrated analysis, were involved in autophagy, mTOR signalling, and osteoclast differentiation pathways. Moreover, their expressions were positively correlated with activated dendritic cells in AA samples.Conclusion: Our findings highlight the roles of DDIT4 and NCF2, in AA progression, providing potential insights for further mechanistic exploration of AA.","PeriodicalId":6981,"journal":{"name":"Acta Haematologica","volume":" ","pages":"1-12"},"PeriodicalIF":1.7,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143405126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the survival rates have been gradually improving in recent years, the cure rate is still not optimistic enough. Therefore, it is necessary to continue exploring the causes of MM.Methods: This study utilizes Mendelian randomization (MR) analysis to establish the connection between inflammatory factors, immune cells, and the occurrence of MM.Results: In MR studies, a significant correlation was observed between interleukin-1 receptor antagonist (IL-1Ra), tumor necrosis factor receptor 1 (TNFR1), memory B-cell percentage of B cells (memory B-cell %B cells), and immunoglobulin D-positive, CD24-negative percentage B cells (IgD+ CD24- %B cells) with the onset of MM. In particular, IgD+ CD24- %B cells showed a statistically significant inverse relationship with the development of MM (p < 0.05, OR <1), whereas IL-1Ra, TNFR1, and memory B-cell %B cells displayed a positive association with the onset of MM (p < 0.05, OR >1). These findings contribute valuable insights to the understanding of the pathogenesis of MM.Conclusion: This study emphasizes the significant role of inflammatory factors and immune cells in multiple myeloma (MM) progression. IL-1Ra, TNFR1, and memory B-cell percentages are identified as risk factors, while IgD+ CD24- %B cells may protect against progression, suggesting new immunomodulatory treatment strategies. However, research on IgD+ CD24- %B cells and MM is limited, necessitating future studies to clarify their mechanisms and effects on the tumor microenvironment. There is also an urgent need for clinical trials to assess therapies targeting these cells, as well as long-term follow-ups to understand their dynamic changes in relation to disease progression.
