Summary: Although iron overload is a clinical challenge, little is known about the clinical impact of HFE-variants in myelodysplastic syndromes. The study found that HFE-variants H63D and C282Y are frequently detected in Austrian MDS patients, who have higher ferritin levels at diagnosis, accumulate iron slightly faster, and have a better progression-free survival than non-mutated patients.

Summary: In this study, iron was found to be a promoter of leukemogenesis in mice up to a peak iron dose, but further iron loading decreased the risk of AML. Iron chelation therapy showed partial effectiveness in reducing the incidence of AML, but intervention should be done before extreme iron overload to maximize its benefits.

Summary: Iron plays an important role in the survival and reproduction of fungal pathogens, and there is evidence linking invasive fungal infections to iron or iron overload. Understanding the association between iron and iron overload with susceptibility to invasive fungal infections is crucial, especially for patients with hematological malignancies.

Summary: Myelodysplastic syndromes and myeloproliferative neoplasms are hematologic diseases associated with bone marrow failure, and transfusion of red blood cells is necessary but leads to iron overload. Therefore, iron chelation therapy plays a crucial role in anemic patients.

Summary: Iron overload is harmful to elderly patients with low-risk myelodysplastic syndromes (MDS), especially those with cardiovascular disease. A randomized study has shown improved event-free survival with Iron Chelation Therapy (ICT) in these patients. Further research is needed to better understand the benefits of ICT.

Summary: Thalassaemia is a genetic disorder causing anaemia and dependence on transfusions, with recent clinical advancements leading to reduced mortality and potential future gene therapies. Research revealed older patients with more iron-related comorbidities and complications, while younger patients had excess liver and heart iron and were on combination chelation therapy.

Summary: This study analyzed the benefits of the revolution in the management of beta-thalassemia major. The results showed that chelation therapy significantly optimized the indices and increased the proportion of patients with chelation success. Continuous magnetic resonance imaging and prolonged intensified chelation therapy can help patients achieve clearance of cardiac and liver iron load and reduce mortality.

Summary: Thalassemia is a monogenic autosomal recessive disorder caused by mutations, which affect hemoglobin production. Conventional therapeutic methods such as transfusion and iron chelation therapy have limitations, leading to the demand for advanced therapies. Nanotechnology-based applications have emerged as simple, convenient, and cost-effective methods for theragnostics. This review summarizes the potential of nanotechnology in developing theragnostic approaches for diagnosing thalassemia-causing gene mutations and employing nano-based therapeutic procedures.

Summary: The study found that the degree of iron accumulation in the bone marrow detected by Perls staining is associated with the overall survival of MDS patients. A higher grade of iron storage is correlated with lower survival rates. Additionally, bone marrow iron overload and transfusion dependency negatively impact on patient survival.

Summary: Combination chelation therapy is a viable option for transfusion-dependent thalassemia patients who have not achieved iron balance with monotherapy or need intensified treatment for rapid iron reduction. It allows for a more personalized approach, improving tolerability, adherence, and quality of life. Real-life data highlights the importance of compliance in achieving meaningful reduction in iron overload compared to monotherapy.

Summary: Iron plays essential roles in cardiovascular diseases, with iron deficiency having detrimental effects in heart failure and pulmonary arterial hypertension patients. Ferroptosis, an iron-dependent cell death, has been reported in cardiomyopathy, atherosclerotic cardiovascular disease, and myocardial ischemia/reperfusion injury. Iron chelation therapy may be a potential strategy to address iron overload-related disorders in CVD.
