Patients suffering from iron overload can experience serious complications. In such patients, various organs, such as endocrine glands and liver, can be damaged. Although iron is a crucial element for life, iron overload can be potentially toxic for human cells due to its role in generating free radicals. In the past few decades, there has been a major improvement in the survival of patients who suffer from iron overload due to the application of iron chelation therapy in clinical practice. In clinical use, deferoxamine, deferiprone, and deferasirox are the three United States Food and Drug Administration-approved iron chelators. Each of these iron chelators is well known for the treatment of iron overload in various clinical conditions. Based on several up-to-date studies, this study explained iron overload and its clinical symptoms, introduced each of the above-mentioned iron chelators, and evaluated their advantages and disadvantages with an emphasis on combination therapy, which in recent studies seems a promising approach. In numerous clinical conditions, due to the lack of accurate indicators, choosing a standard approach for iron chelation therapy can be difficult; therefore, further studies on the issue are still required. This study aimed to introduce each of these iron chelators, combination therapy, usage doses, specific clinical applications, and their advantages, toxicity, and side effects.

BackgroundInflammatory Bowel Disease (IBD) affects the quality of life. Patient education and support needs are crucial components of comprehensive chronic illness care. The main purposes of this review were to (i) explore the informational and supportive needs of these patients to improve the quality of life in the existing literature and (ii) identify the gaps related to the needs of the patients in articles.MethodsThe scoping review is based on the Daudt methodological framework, a modified version of Arksey and O'Malley. Electronic databases were extensively searched from January 01, 2000 to April 30, 2022. Four electronic databases (PubMed/Medline, CINAHL, APA PsycInfo, Psychology and Behavioral Sciences Collection, APA PsycArticles, and ProQuest) were searched using controlled vocabulary, and specific keywords. The searched terms were matched to each database. We manually searched two key journals, namely the Journal of Inflammatory Bowel Disease and the Journal of Crohn's and Colitis.ResultsIn the review, 75 studies on the assessment of the information and support needs of patients with IBD were reviewed. In this regard, 62 and 53 studies were regarding information needs and support needs, respectively. Most of the information needs of patients with IBD reported in the studies were related to diet needs, and educational needs were the most essential support needs.ConclusionsHealth policymakers and managers can develop care and educational programs related to this disease in health centers according to the needs of the patients. Health professionals, especially gastroenterologists, are the primary referral sources for information on patients. Therefore, gastroenterologists can take the lead in planning and educating the patients and sharing their decisions.Systematic review registrationOSF, https://doi.org/10.17605/OSF.IO/3MWGJ.
