ABSTRACT Background and Aims Thalassemia is an inherited hemoglobin disorder characterized by ineffective erythropoiesis, chronic anemia, and progressive multisystem complications that require lifelong management. Current treatment relies on regular red blood cell transfusions, iron chelation therapy, and supportive multidisciplinary care, while hematopoietic stem cell transplantation offers a curative option for selected patients. Although gene‐based therapies and novel pharmacological agents have expanded therapeutic options, their widespread implementation is limited by cost, accessibility, and long‐term safety considerations. This article summarizes contemporary management strategies for α and β thalassemia, with particular emphasis on the recent emergence of the FDA‐approved oral pyruvate kinase activator, mitapivat. Methods A structured literature review was conducted using PubMed and PubMed Central. Searches included the terms “thalassemia,” “mitapivat,” “pyruvate kinase activator,” “gene therapy,” “hydroxyurea,” and “luspatercept.” Priority was given to recent systematic reviews, clinical practice guidelines, pivotal phase II and III clinical trials, regulatory publications, and peer‐reviewed studies relevant to current therapeutic practice. Results Conventional therapies remain essential but are associated with significant limitations, including transfusion dependence, iron overload, and treatment‐related complications. Curative strategies such as hematopoietic stem cell transplantation and gene therapy are effective in selected patients but remain constrained by donor availability, toxicity, cost, and limited accessibility. Emerging pharmacological therapies target ineffective erythropoiesis and iron dysregulation. Phase III ENERGIZE and ENERGIZE‐T trials demonstrated that mitapivat significantly improved hemoglobin response in non‐transfusion‐dependent disease and reduced transfusion burden in transfusion‐dependent disease, with an acceptable safety profile, leading to FDA approval as the first oral therapy for adults with α or β thalassemia. Conclusion Mitapivat represents a significant advance in thalassemia management by targeting erythrocyte metabolism and providing the first FDA‐approved oral treatment for anemia in adults with α or β thalassemia. Multi‐year follow‐up and real‐world studies are needed to further define its durability, safety, and role within evolving treatment strategies.

OBJECTIVES
Peripheral artery disease (PAD) is a common atherosclerotic disorder characterized by progressive arterial narrowing in the limbs. This study aims to determine the efficacy and safety of rivaroxaban, focusing on major cardiovascular events, limb outcomes, and bleeding risks.
METHODS
PubMed, Cochrane, and EMBASE were searched for RCTs and non-randomized comparative studies that compared rivaroxaban, either alone or in combination with aspirin, to placebo or standard care such as antiplatelet therapy. Risk ratios and hazard ratios with 95% confidence intervals were pooled using R v4.5.1 with an appropriate random-effects model applied. Subgroup analyses were performed according to rivaroxaban plus aspirin versus rivaroxaban alone.
RESULTS
39,991 participants across six studies were included. Compared with control, use of rivaroxaban was linked to a significant reduction in composite efficacy outcomes (RR= 0.84, 95%CI 0.78-0.91, p<0.001), risk of acute limb ischemia (RR= 0.65, 95% CI 0.55-0.78, p<0.001), and thromboembolism (RR= 0.60, 95% CI 0.38-0.97, p=0.037). Although rivaroxaban plus aspirin failed to show a significant reduction in the risk of amputation, rivaroxaban alone reported a significant risk reduction (RR=0.50, 95% CI 0.30-0.85, p=0.003). However, its use was associated with a significantly higher risk of major bleeding (HR=1.54, 95% CI 1.38-1.72, p<0.001) and International Society of Thrombosis and Hemostasis-defined bleeding (RR= 1.45, 95% CI 1.19-1.76, p<0.001). No significant differences were observed for stroke, myocardial infarction, major adverse limb events, fatal bleeding, mortality, or cardiovascular mortality.
CONCLUSION
Rivaroxaban-based therapy reduced the trial-defined composite efficacy outcome, acute limb ischemia, and thromboembolism in patients with PAD, but increased the risk of major bleeding. These findings support individualized use of rivaroxaban-based therapy in carefully selected patients, balancing ischemic and limb-protective benefits against bleeding risk.
