An Epidemiological Study to Assess Iron Overload Using MRI in Patients With Transfusional Siderosis (TIMES Study)

Australia243 participantsStarted 2013-02

Plain-language summary

Iron, one of the most common elements in nature and the most abundant transition metal in the body, is readily capable of accepting and donating electrons. This capability makes iron a useful component of various, essential biochemical processes. Despite the essential role of iron, the excess of iron is toxic to the human body. It is critical for the human body to maintain iron balance, since humans have no physiologic mechanism for actively removing iron from the body. The development of iron overload occurs when iron intake exceeds the body's capacity to safely store the iron in the liver, which is the primary store for iron. Long-term transfusion therapy, a life-giving treatment for patients with intractable chronic anemia is currently the most frequent cause of secondary iron overload. The mounting evidence regarding the mortality and morbidity due to chronic iron overload in transfusion dependent anaemias has led to the establishment of guidelines that aim the improvement of patient outcomes. Further prospective studies are warranted in order to assess the impact of iron overload in patients with acquired anaemias. In this study, non-invasive R2- and T2\*-MRI techniques were applied to the liver and the heart, respectively, to complement the primary variable (serum ferritin) assessed in patients with various transfusion-dependent anaemias. The main objective of this study was to assess the prevalence and severity of cardiac and liver siderosis in patients with transfusional siderosis. This study was also aim to establish possible correlations between cardiac and liver iron levels with clinical effects in patients with different transfusion-dependent anaemias. Patients were eligible for enrollment irrespective of receiving chelation therapy or not (and irrespective of the chelating agent used).

Inclusion Criteria: * Age ≥18 years * Confirmed clinical diagnosis of one of the following disease states: 1. Myelodysplastic syndromes, 2. Thalassaemia major, 3.Other anaemias (e.g. NTDT, SCD, Diamond-Blackfan anaemia, aplastic anaemia, myeloproliferative disease) * Lifetime history of at least 20 units of red blood cell transfusions AND serum ferritin level \> 500 ng/ml; patients with NTDT are not required to have a minimum of 20 units of red blood cell transfusions, but must have serum ferritin level \> 300 ng/ml (serum ferritin for all patients must be measured up to 1 month prior to enrollment) * Written informed consent obtained prior to any procedure required by this protocol Exclusion Criteria: Any condition that does not allow the MRI test to be performed: 1. Cardiac pacemaker, 2. Ferromagnetic metal implants other than those approved as safe for use in MR scanners (Example: some types of aneurysm clips, shrapnel), 3.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
