INTRODUCTION Major thalassemia patients need lifelong transfusions. The consequence of these repeated transfusions is iron accumulation in different organs. The main aim of the present study was to investigate the correlation between heart, liver and pancreas hemosiderosis in thalassemic patients from Iran. METHODS This cross-sectional study was conducted on 164 major thalassemia patients at ...

CONTEXT T2* magnetic resonance imaging (MRI) is being increasingly used for the assessment of organ iron content in thalassemics, but cost is a major prohibitive factor for repeated measurements. If serum ferritin correlates well with the T2* MRI liver and heart, it will be economical and more simple tool to assess organ iron deposition. AIMS The aim of this study was to find out the relation...

BACKGROUND Frequent blood transfusion is often associated with iron overload. Proper use of iron chelators to treat iron overload requires an accurate measurement of iron levels. Magnetic resonance T2-star (T2* MRI) can measure iron level in the heart and liver. Our goal was to see whether an association exists between serum ferritin level and T2* MRI in patients with major beta thalassemia. ...

background: iron-mediated cardiomyopathy is the main complication of thalassemia major (tm) patients. therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. the aim of this study was to evaluate the efficacy of tissue doppler imaging (tdi) to study cardiac iron overload in patients with tm using t2* magnetic resonance (mr) as the gold-standard...

Introduction: Noninvasive magnetic resonance imaging (MRI) and targeted drug delivery systems, usually referred to as theranostic agents, are being developed to enable detection, site-specific treatment, and long-term monitoring.   Materials and Methods: To elucidate the effects of coating on cellular uptake and biodistribution of n...

There are few papers on the combination therapy of deferiprone (DFP) and deferasirox (DFX) in iron-overloaded patients with transfusion-dependent β-thalassemia major (β-TM). A total of 6 patients with β-TM (5 males and 1 female) with a mean age of 23.8±5.8 years (ranging from 17 to 31) used this treatment regimen. The mean doses of DFP and DFX were 53.9±22.2 and 29.3±6.8 mg/kg/day, respectively...

بیماران تالاسمی ماژور به علت تزریقات مکرر خون در معرض اضافه بار آهن در بافت های مختلف بدن به ویژه قلب و کبد هستند و 70 % علت مرگ و میر بیماران تالاسمی ، نارسایی قلبی ناشی از سیدروز میوکارد است . با توجه به شیوع بالای تالاسمی در کشور ، بر آن شدیم تا ارتباط میزان فریتین سرم و t2*mri قلب و کبد را بررسی نماییم تا با داشتن اطلاعات جامع تری از میزان بار آهن بدن بتوانیم به درمان موثرتر و بهبود کیفیت ز...

BACKGROUND Iron-loaded cardiac complication is the essential cause of mortality in patients with thalassemia. Early detection and treatment of cardiac over-load can reduce mortality. OBJECTIVES The current study aimed to evaluate the relationship between serum ferritin levels and T2* magnetic resonance imaging (MRI) of heart and liver and liver iron concentration (LIC) to diagnose iron over l...

BACKGROUND Transfusional therapy for thalassemia major and sickle cell disease can lead to iron deposition and damage to the heart, liver, and endocrine organs. Iron causes the MRI parameters T1, T2, and T2* to shorten in these organs, which creates a potential mechanism for iron quantification. However, because of the danger and variability of cardiac biopsy, tissue validation of cardiac iron ...

BACKGROUND Cardiac complications due to iron overload are the most common cause of death in patients with thalassemia major. The aim of this study was to compare iron chelation effects of deferoxamine, deferasirox, and combination of deferoxamine and deferiprone on cardiac and liver iron load measured by T2* MRI. METHODS In this study, 108 patients with thalassemia major aged over 10 years wh...
