While effective, it carries significant bleeding risks, with annual rates ranging from 10-17% for all events and 2-5% for major bleeding. Anemia is an independent risk factor for anticoagulation-associated bleeding; however, guidelines lack recommendations for anemia screening and management before initiation. In a retrospective analysis of 170 anticoagulated patients (mean age 63.7; 96 males, 74 females), 51.2% had baseline anemia. Anemia severity was significantly associated with bleeding events (χ²=15.7, p=0.003). Multivariate analysis confirmed that moderate (aOR=0.26, 95% CI:0.08-0.82, p=0.021) and no anemia (aOR=0.42, 95% CI:0.22-0.82, p=0.011) were associated with lower bleeding risk than mild anemia, while severe anemia remained uninterpretable due to small sample size. Patients aged ≥65 had higher bleeding risk (OR=2.8, 95% CI:1.5-5.1, p<0.01), though this did not reach significance in multivariate analysis (aOR=1.80, 95% CI:0.95-3.41, p=0.073). Multivariate analysis confirmed higher bleeding risks for warfarin (aOR=4.13, 95% CI:1.91-8.96, p<0.001) and rivaroxaban (aOR=3.67, 95% CI:1.69-7.97, p=0.001) compared to apixaban. Our study found an association between anemia and bleeding events, though severe anemia did not correlate with bleeding, possibly due to small sample size. Direct oral anticoagulants like apixaban and rivaroxaban present lower bleeding risks than warfarin. Given anemia's role in bleeding risk, we recommend routine screening before initiating anticoagulation to improve patient safety. Early assessment may help reduce bleeding complications, particularly in high-risk populations. Future studies should focus on multi-center trials to validate these findings and explore anemia subtypes.</p>","PeriodicalId":93942,"journal":{"name":"Clinical hematology international","volume":"7 2","pages":"34-45"},"PeriodicalIF":0.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12121077/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The availability of several new treatment classes has brought about improvements in outcomes, but with median survival in the RRMM setting at only ~32 months, a review of current standard of care treatments and considerations for optimizing care in this setting is warranted. Here, we discuss our preferred approach to treating patients with RRMM, based on our collective experience across the Gulf region. We present position statements for the treatment of lenalidomide-sensitive and -refractory patients, as well as for those patients experiencing late relapse. We discuss the major impact that anti-CD38 agents daratumumab and isatuximab have had on the management of RRMM, which is reflected in our preferred use of daratumumab-based regimens across the lenalidomide-sensitive and -refractory settings.

From a safety perspective, the addition of anti-CD38 monoclonal antibodies into the triplet therapies did not raise additional safety concerns. Based on the promising results, the National Comprehensive Cancer Network (NCCN) Guidelines Version 1.2025 had updated the quadruplet therapy incorporating anti-CD38 monoclonal antibodies with VRd-based therapies as the primary therapy for both transplantation-eligible and transplantation-ineligible NDMM patients. Thus, a panel of experts in hematology and oncology with extensive experience in the treatment of NDMM was convened in 2024 to develop consensus recommendations based on recent evidence from pivotal clinical trials and real-world practices, providing clear guidance for optimizing treatment strategies in both transplantation-eligible and transplantation-ineligible patients. The main topics identified for discussion and recommendation were: (i) the benefits and indications for quadruplet therapy for NDMM; (ii) the optimization of quadruplet therapy strategies; (iii) the management and monitoring of potential adverse events for quadruplet therapy, and (iv) the impact of quadruplet regimens on tandem stem cell transplantation and maintenance treatment. Recommendations were then presented to the entire panel for further discussion and amendment before voting.
