However, new drugs that do not rely on the replacement of the deficient factor require new approaches to laboratory monitoring, as factor VIII (FVIII) or factor IX (FIX) assays are no longer adequate. Non-factor therapies come in many different forms, that have one thing in common: they all increase thrombin generation. Their main adverse effect is thrombosis which may occur when too much thrombin is formed. This is the perfect mirror image of anticoagulant treatment, which always diminishes the amount of thrombin formed and has bleeding as its main adverse effect. Thrombin-forming capacity is decreased in congenital bleeding disorders and increased in prothrombotic conditions, indicating it governs bleeding and thrombosis. Therefore, the thrombin generation assay (TGA) is a logical tool for monitoring non-factor therapies, offering a comprehensive assessment of hemostatic balance. TGA identifies patients with severe bleeding, helps to optimize bypassing therapy, and detects hypercoagulability, making it ideal for guiding and monitoring hemophilia treatment with non-factor therapies. It also assesses the efficacy and safety of combined therapies, including non-factor therapies with bypassing agents or FVIII/FIX concentrates. The purpose of this paper is to review the current state of knowledge regarding the use of TGA to monitor novel hemophilia therapies. It will address controversies, limitations, and knowledge gaps related to the integration of TGA into personalized medicine in routine clinical practice.</p>","PeriodicalId":14120,"journal":{"name":"International Journal of Laboratory Hematology","volume":"47 2","pages":"212-220"},"PeriodicalIF":2.2,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijlh.14406","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, we investigated the impact of base excision repair (BER) gene polymorphisms on acute myeloid leukemia (AML) risk and pathogenesis.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>In total, 106 patients with AML and 191 healthy controls were included in the study, wherein polymorphisms in four BER genes (<i>APEX1</i>, <i>MUTYH</i>, <i>OGG1</i>, and <i>XRCC1</i>) were examined.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Notably, the <i>APEX1</i>-656 T&gt;G polymorphism exhibited a significant association with AML risk in the recessive (TT vs. TG + GG) (<i>p</i> = 0.046) and co-dominant models (TT vs. GG) (<i>p</i> = 0.02). Assessing <i>APEX1</i> expression levels, <i>APEX1</i> expression was elevated in the bone marrow of patients with AML compared with that in controls (<i>p</i> = 0.02). Subsequently, we compared the percentages of CD34+ cells between the <i>APEX1</i> high or low expression groups, revealing a significant difference (high vs. low = 29.9% vs. 11.5%, <i>p</i> = 0.01). Additionally, we observed reduced <i>APEX1</i> expression in HL60 cells differentiated with all-trans retinoic acid (<i>p</i> &lt; 0.001). We hypothesized that <i>APEX1</i> expression could correlate with stemness and analyzed its expression in stem and differentiated cells.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>In the GSE48558 dataset, AML cells and normal CD34+ cells expressed <i>APEX1</i> at higher levels than did granulocytes (<i>p</i> &lt; 0.01). Functional experiments revealed that <i>APEX1</i> knockdown led to a reduction in AML cell proliferation. These findings indicated that <i>APEX1</i> polymorphisms were a potential risk factor for AML and highlighted the important role of <i>APEX1</i> in regulating AML cell differentiation and proliferation.</p>\u0000 </section>\u0000 </div>","PeriodicalId":14120,"journal":{"name":"International Journal of Laboratory Hematology","volume":"47 2","pages":"276-287"},"PeriodicalIF":2.2,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ijlh.14401","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142634990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
