Several gene therapies are now available for congenital blood disorders, notably for hemophilia and hemoglobinopathies. In this review, we discuss each of the six therapies that now have regulatory approval for treatment in the United States: Roctavian (valoctocogene roxaparvovec) for hemophilia A, Beqvez (fidanacogene elaparvovec) and Hemgenix (etranacogene dezaparvovec) for hemophilia B, Lyfgenia (lovotibeglogene autotemcel) for sickle cell disease, Zynteglo (betibeglogene autotemcel) for β-thalassemia, and Casgevy (exagamglogene autotemcel) for either sickle cell disease or β-thalassemia. The underlying principles for these treatments vary and include both in vivo and ex vivo methods, lentiviral and adeno-associated viral (AAV) vectors, and gene silencing by the CRISPR-Cas9 gene editing system. Consequently, they pose correspondingly disparate risks and benefits when compared to other treatment modalities and to each other. Although long-term effects are not yet entirely understood, given the novelty of these therapies, knowledge on patient outcomes is continuously increasing. Overall, results are very encouraging, often freeing patients from the need for coagulation factor or red blood cell (RBC) infusions, albeit that for some of these diseases there is room for further improvement in terms of safety and therapeutic durability, which may be achieved with next-generation gene therapy products.

The transition period from pediatric to adult medical system represents a critical stage for ensuring continuous and tailored care. This narrative review synthesizes current evidence on transitional care for hemophilia patients, focusing on nursing-led interventions. A structured search of literature from 2010 to 2024 was conducted, drawing from key databases including PubMed, Embase, and CINAHL, as well as major guideline repositories and professional society publications. The findings from this analysis systematically summarize the challenges and intervention strategies in the transitional period. At the patient level, there are problems such as lack of self-management ability, psychosocial adaptation disorder and treatment compliance decline, particularly among those with severe disease; this period also requires a deliberate shift in responsibility from parents to the young person, a process that requires careful support for both. At the level of medical system, the transition difficulty is exacerbated by the differences between pediatric and adult medical models, the lack of multidisciplinary cooperation and the uneven distribution of resources, all of which hinder seamless care continuity. At present, the effective intervention strategies include: the implementation of structured transition plan, the training of self injection and emergency treatment skills, the provision of psychosocial support, and the establishment of nurse led multidisciplinary cooperation mode. During the transition period, nurses play the core role of assessment planning, education empowerment, coordination advocacy and psychological support. In the future, it is necessary to strengthen the development of digital tools, research on long-term health outcomes and policy support, so as to optimize the transitional nursing system and ensure the continuity of life-long health management of patients across all severity levels. While this review synthesizes global evidence, it is pertinent to note that challenges of resource access, particularly the urban-rural divide in availability of factor concentrates, novel therapies, and home-treatment programs, are often more pronounced in many developing countries, including China. The insights gathered underscore the need for standardized, nurse-coordinated transitional care protocols to inform both clinical practice and healthcare policy, aiming to bridge current gaps in service delivery and improve long-term patient outcomes.</p>","PeriodicalId":15166,"journal":{"name":"Journal of Blood Medicine","volume":"17 ","pages":"558200"},"PeriodicalIF":2.1,"publicationDate":"2026-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12912012/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146219970","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}
