Abstract
Hemochromatosis (HC) is characterized by the progressive accumulation of iron in the body, resulting in organ damage. Endocrine complications are particularly common, especially when the condition manifests in childhood or adolescence, when HC can adversely affect linear growth or pubertal development, with significant repercussions on quality of life even into adulthood. Therefore, a timely and accurate diagnosis of these disorders is mandatory, but sometimes complex for hematologists without endocrinological support. This is a narrative review focused on puberty and growth disorders during infancy and adolescence aiming to offer guidance for diagnosis, treatment, and proper follow-up. Additionally, it aims to highlight gaps in the existing literature and emphasizes the importance of collaboration among specialists, which is essential in the era of precision medicine.

Abstract
INTRODUCTION Around 5% of the world's population is expected to have some degree and type of thalassaemia. Beta thalassaemia (BT) occurs due to a deficient production of the beta-globin chain of haemoglobin. Extramedullary haematopoiesis (EMH) is one of the complications of BT, mainly observed in minor/intermedia subtypes. EMH is the production of blood cells outside the marrow as a compensatory response to longstanding hypoxia. Due to chronic transfusions, it is not expected in patients with beta-thalassaemia major (BTM). However, there are increasingly reported cases of EMH in BTM. The incidence of EMH in BTM is thought to be <1%. We aim to pool the available data and provide cumulative evidence on the occurrence of EMH in BTM patients. METHODS This is a systematic review of case reports, series, and retrospective studies that presented data on the occurrence of EMH in BTM patients. Data were recorded and analyzed in Microsoft Excel 2016 and SPSS 26. The protocol has been registered in PROSPERO: CRD42021242943. RESULTS Data from 253 cases of EMH in BTM patients were extracted with a mean age of 35.3 years. Mean haemoglobin at presentation with EMH was 8.2 mg/dL. Lower limb weakness was the most common presenting feature (N = 23) (paraspinal EMH). Magnetic resonance imaging (MRI) was the most widely used diagnostic modality (226). Overall, blood transfusion was the commonest reported treatment (30), followed by radiotherapy (20), surgery (15), hydroxyurea (12), steroids (6), and exchange transfusion (2). An outcome was reported in 20% of patients, all recovered, except one who died as a result of nosocomial infection. CONCLUSION EMH is rare in BTM and can occur in any organ system with varied clinical features. MRI can effectively diagnose EMH, and conservative management has similar results compared to invasive treatments. Larger studies, focussing on outcomes may enhance guidelines on preventive and therapeutic strategies for managing EMH in BTM.KEY MESSAGESExtramedullary haematopoiesis is a rare complication in beta thalassaemia. Although it is more common in non-transfusion dependent thalassaemia, increasingly reported cases suggest a higher prevalence of EMH in TDT than what is known before.There are no clear guidelines on the management of EMH in TDT, with reported patients showing similar outcomes with conservative invasive treatment modalities.More extensive and preferably prospectively designed studies are required focussing on the management of EMH and its outcomes in patients with TDT to formulate evidence-based guidelines.

Abstract
The conventional treatment of β-thalassemia (β-TM) patients is based on the correction of anemia through regular blood transfusions and iron chelation therapy. However, allogeneic hematopoietic stem cell transplantation (HSCT) remains the only currently available technique that has curative potential. Variable frequency and severity of long-term growth and endocrine changes after conventional treatment as well as after HSCT have been reported by different centers. The goal of this mini-review is to summarize and update knowledge about long-term growth and endocrine changes after HSCT in patients with β-TM in comparison to those occurring in β-TM patients on conventional treatment. Regular surveillance, early diagnosis, treatment, and follow-up in a multi-disciplinary specialized setting are suggested to optimize the patient's quality of life (www.actabiomedica.it).

Abstract
Extramedullary hematopoiesis (EMH) is a well-known complication of beta thalassemia major and frequently occurs in typical sites such as liver or spleen. However, when presenting in unusual sites as sacrum, other diagnosis should be excluded by histopathology prior to deciding on treatment plan.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease, with multisystemic involvement. Hemoglobin E/beta-thalassemia (HbE/beta-thalassemia) is the genotype responsible for approximately one-half of all severe beta-thalassemia worldwide. When beta-thalassemia and SLE coexist, SLE seems to have a more severe course. Here we report a 32-year-old female who presented with dizziness and fatigue was found to have severe hemolytic anemia with thrombocytopenia. Upon further evaluation, she was diagnosed with HbE/beta-thalassemia and SLE, which is a very rare association. In SLE patients, anemia usually results from the disease itself, but it is important to think of other coexisting conditions like thalassemia.

Abstract
Secondary iron overload is a common complication in the context of hematological diseases, as iron accumulates due to different mechanisms including chronic transfusion, increased gastrointestinal absorption, chronic hemolysis and underlying genetic defects leading to an increase in gastrointestinal absorption of iron. Since the body does not have a mechanism to excrete excess iron, it gets deposited in the heart, endocrine organs, and the liver with the latest being affected less commonly than in primary iron overload disorders like hemochromatosis. Patients with hemoglobin H disease, which is a type of α-thalassemia, are usually transfusion independent, except in occasions where an external stressful factor leads to a drop in hemoglobin and necessitates blood transfusion. Despite this, secondary iron overload is commonly encountered in these patients due to increased gastrointestinal absorption of iron. To avoid the complications associated with iron overload, these patients are usually monitored with serum ferritin, which is an inexpensive widely available method to monitor iron overload. MRI of the liver (Ferriscan) is a more sensitive and specific method to monitor these patients and avoid the long-lasting and sometimes irreversible effect of secondary iron overload. Here we present an interesting case of a patient with hemoglobin H disease, who was monitored with serum ferritin. She had a serum ferritin level considered as a borderline risk for morbidities secondary to iron overload, and an MRI of her liver (Ferriscan) showed significant iron deposition in the liver associated with increased risk of complications secondary to iron overload.

Abstract
Primary hemochromatosis is an inherited disorder, and the homeostatic iron regulator (HFE) gene C282Y mutation is a common cause of hemochromatosis in Europe. We are reporting a case of a 56-year-old female known to have hemochromatosis with the HFE gene C282Y mutation with a serum ferritin level of 482 μg/L who underwent heart and liver T2* MRI which showed no evidence of iron overload – neither in the heart nor in the liver. This indicates that there is a discrepancy between serum ferritin and liver iron concentration by MRI and the superiority of T2* MRI in diagnosis and follow-up of iron overload in patients with hereditary hemochromatosis.

Abstract
Iron overload is a common complication in patients with chronic renal failure treated with dialysis prior to the availability of recombinant human erythropoietin therapy. Iron overload was the result of hypoproliferative erythroid marrow function coupled with the need for frequent red blood cell transfusions to manage symptomatic anemia. The repetitive use of intravenous iron with or without the use of red blood cell transfusions also contributed to iron loading and was associated with iron deposition in liver parenchymal and reticuloendothelial cells. Here we report a 56-year-old female with end-stage renal failure who underwent kidney transplant twice and found to have iatrogenic iron overload with excess intravenous iron treated conservatively.

Abstract
BACKGROUND The clinical application of cardiovascular magnetic resonance (CMR) T2 and T2* mapping is currently limited as ranges for healthy and cardiac diseases are poorly defined. In this meta-analysis we aimed to determine the weighted mean of T2 and T2* mapping values in patients with myocardial infarction (MI), heart transplantation, non-ischemic cardiomyopathies (NICM) and hypertension, and the standardized mean difference (SMD) of each population with healthy controls. Additionally, the variation of mapping outcomes between studies was investigated. METHODS The PRISMA guidelines were followed after literature searches on PubMed and Embase. Studies reporting CMR T2 or T2* values measured in patients were included. The SMD was calculated using a random effects model and a meta-regression analysis was performed for populations with sufficient published data. RESULTS One hundred fifty-four studies, including 13,804 patient and 4392 control measurements, were included. T2 values were higher in patients with MI, heart transplantation, sarcoidosis, systemic lupus erythematosus, amyloidosis, hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM) and myocarditis (SMD of 2.17, 1.05, 0.87, 1.39, 1.62, 1.95, 1.90 and 1.33, respectively, P < 0.01) compared with controls. T2 values in iron overload patients (SMD = - 0.54, P = 0.30) and Anderson-Fabry disease patients (SMD = 0.52, P = 0.17) did both not differ from controls. T2* values were lower in patients with MI and iron overload (SMD of - 1.99 and - 2.39, respectively, P < 0.01) compared with controls. T2* values in HCM patients (SMD = - 0.61, P = 0.22), DCM patients (SMD = - 0.54, P = 0.06) and hypertension patients (SMD = - 1.46, P = 0.10) did not differ from controls. Multiple CMR acquisition and patient demographic factors were assessed as significant covariates, thereby influencing the mapping outcomes and causing variation between studies. CONCLUSIONS The clinical utility of T2 and T2* mapping to distinguish affected myocardium in patients with cardiomyopathies or heart transplantation from healthy myocardium seemed to be confirmed based on this meta-analysis. Nevertheless, variation of mapping values between studies complicates comparison with external values and therefore require local healthy reference values to clinically interpret quantitative values. Furthermore, disease differentiation seems limited, since changes in T2 and T2* values of most cardiomyopathies are similar.

Abstract
Iron overload is commonly seen in the context of hematological diseases in patients who require frequent transfusions. On the other hand, an association between autoimmune hemolytic anemia complicating chronic lymphocytic leukemia and iron overload is unusual. Here, we report 2 cases of iron overload in patients with a background of chronic lymphocytic leukemia complicated by autoimmune hemolytic anemia. Both patients were found to have a high liver iron concentration on liver MRI (FerriScan). This observation raises the important question about the value of screening for iron overload in this group of patients.

Abstract
Due to the recent alarming increase in the incidence of hepatocellular carcinoma (HCC) in thalassemias, the present report reviews briefly the frequency, the major risk factors, and the surveillance of HCC in β-thalassemias. Over the past 33 years, 153 cases of HCC were reported in patients with thalassemia, mainly in Italy and Greece. Among HCV-infected patients, additional factors promoting the development of HCC included: advanced age, male sex, chronic hepatitis B (CHB) co-infection, and iron overload. For early diagnosis of HCC, sequential ultrasound screening is recommended especially for thalassemia patients with chronic hepatitis C (CHC), which coincides with (one or more) additional risk factors for HCC. Here we report also the preliminary data from thalassemic patients, above the age of 30 years, followed in 13 ICET-A centers. The total number of enrolled patients was 1,327 (males: 624 and 703 females). The prevalence of HCC in thalassemia major patients [characterized by transfusion-dependency (TDT)] and thalassemia intermedia [characterized by nontransfusion dependency (NTDT)] was 1.66 % and 1.96 %, respectively. The lowest age at diagnosis of HCC was 36 years for TDT and 47 years for NTDT patients. We hope that this review can be used to develop more refined and prospective analyses of HCC magnitude and risk in patients with thalassemia and to define specific international guidelines to support clinicians for early diagnosis and treatment of HCC in thalassemic patients.

Clin Ther 2019; 42:322-337.e2. [PMID: 31882227 DOI: 10.1016/j.clinthera.2019.12.003] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 11/25/2019] [Accepted: 12/04/2019] [Indexed: 01/27/2023]
Abstract
PURPOSE β-Thalassemia is an inherited blood disorder characterized by reduced or no production of adult hemoglobin. Systematic identification of the burden of β-thalassemia with contemporary treatments is lacking in published literature. Thus, a gap exists in understanding the baseline burden on which to assess future treatments. Therefore, a systematic literature review (SLR) was performed to assess management and outcomes in patients with transfusion-dependent β-thalassemia (TDT) who received long-term transfusion regimens. METHODS Searches of MEDLINE, EMBASE, and 5 conference websites were conducted to identify clinical-practice studies in Italy, France, Germany, Greece, the United States, and the United Kingdom, published since January 2007. The review found 135 articles meeting the SLR criteria. FINDINGS Among patients carrying 2 β-thalassemia mutations, 64%-89% underwent regular transfusions at intervals of between 2 and 4 weeks. Transfusion-associated complications that were reported included iron overload, transfusion reactions, alloimmunization, and infections. Analyses of 42, 25, and 73 studies reporting liver iron concentration (median, 8.5 mg/g of dry weight [dw]; interquartile range [IQR], 4.5-11.0 mg/g dw), cardiac T2* magnetic resonance imaging (median, 27.4 ms; IQR, 26.0-30.2 ms), and serum ferritin (median, 1465.0 ng/mL; IQR, 1238.2-1797.0 ng/mL), respectively, showed wide ranges in iron levels and a general trend toward improved iron control in recent years. Adverse transfusion reactions and alloimmunization were reported in ~50% and 10%-20% in patients, respectively. Rates of transfusion-transmitted infections were highly variable by study but were lower in more recent cohorts. Complications stemming from iron overload and underlying disease captured in this SLR included cardiac disease, liver disease, and endocrine and musculoskeletal disorders. Approximately 10% of patients were diagnosed with heart failure, with rates ranging from 2.9% to 20.9% across 6 studies. Other significant complications reported with β-thalassemia included pain (25%-69%), psychiatric disorders (25%-30%), and reduced health-related quality of life. Despite substantial improvements in survival, patients with TDT remained at an increased risk for early mortality. IMPLICATIONS Consistent with improvements in transfusion practices and iron monitoring and management, outcomes in patients with TDT have improved. However, iron overload and disease-associated complications remain a challenge in this population. This review supports the burden of disease affecting patients with β-thalassemia and provides a baseline health status against which to assess future improvements in care.

Abstract
β-thalassemia major (β–TM) is among the most common hereditary disorders imposing high expenses on health-care system worldwide. The patient’s survival is dependent on lifetime blood transfusion which leads to iron overload and its toxicity in various organs including endocrine glands. This article provides an overview of endocrine disorders in beta-TM patients. This single center investigation enrolled 28 β-TM patients (16 males, 12 females) regularly transfused with packed red cell since early years of life. For each patient were determined: age, sex, number of transfusions received, history of splenectomy and anthropometric parameters. All patients underwent an evaluation of hormonal status including growth, gonadal, thyroid, adrenal cortex, and parathyroid glands. Dual-energy X-ray absorptiometry was used to diagnose low bone mass. Assessment of iron overload status was performed by measuring the serum ferritin concentration and the results of magnetic resonance imaging T2*. Growth retardation was found in 16 of the 28 studied patients (57 %). Thirteen among them had delayed puberty. Spontaneous puberty was achieved in 16 cases. Growth hormone (GH) deficiency was found in 10 cases (35 %). Seventeen among the studied patients (60 %) developed disorders of glucose homeostasis. Subclinical hypothyroidism was found in six patients (21 %). Intensive chelation therapy had allowed the reversibility of this complication in five cases. Adrenal Insufficiency was observed in 9 cases (32%). Hypoparathyroidism has occurred in one case. Ten of the 28 studied patients had low bone mass (35%). Twenty-three of the 28 studied patients (82%) had at least one endocrine complication.

Abstract
AIM to evaluate the relationship between uric acid (UA), hepatic and cardiac iron overload (T2*-MRI), ferritin, endocrinological diseases and cardiac complications in a large thalassemia major (TM) cohort. METHODS A total of 369 TM patients (187 men; 33 ± 6 years) were retrospectively studied, from the myocardial iron overload in thalassemia (MIOT) electronic databank. RESULTS Multiple regression model identified male sex (p < 0.001), BMI (p < 0.001) and T2* (p ≤ 0.001) as UA independent correlates. Moreover, UA and derivatives of reactive oxygen species (an oxidative index; r = -0.3; p ≤ 0.05) are inversely correlated. Conversely, the multivariate logistic analysis identified low UA (NANHES-III criteria) as one independent predictor for low global heart T2* (p < 0.5) together with liver iron concentrations (>3 mg/g/dw), heart failure, endocrinopathies, ferritin (>2000 ng/l), alanine transaminase (>40 UI/l) and/or aspartate transaminase (>35 UI/l) and/or glutamyl transferase (>64 UI/l). DISCUSSION UA appears directly associated to T2* and inversely with derivatives of reactive oxygen species, and as such reduced according to increased oxidative stress and cardiac iron overload in TM patients.

Abstract
Failure of pubertal growth, delay or absence of sexual development, infertility and sexual dysfunction due to hypogonadism and defective spermatogenesis are frequent and well recognized disturbances among male patients with transfusion dependent (TD) thalassaemia major (β-thal). These problems are attributed mainly to the damage caused by chronic anaemia and the deposition of excess iron in the pituitary gland and testicles. This is a short review of male pubertal disorders in patients with β-thal written by pediatric endocrinologists and haematologists with an interest and active involvement, in the diagnosis and management of these complications in this group of patients. A vigilant clinical evaluation of growth and puberty, as well as an appropriate hormonal evaluation in poly-transfused (TD β-thal) patients is strongly recommended for early detection and treatment of endocrine dysfunction. Of crucial importance also, is the implementation of an efficient chelation regime from early life, to prevent severe iron load and permanent damage to the endocrine glands, particularly those responsible for gonadal function.

Abstract
INTRODUCTION Hypogonadism is the most frequently reported endocrine complication, affecting 40%-80% of thalassemia major (TM) patients. The prevalence and severity of hypogonadism in TM varies among studies, depending on patients' age, genotype, transfusion frequency and starting age and efficiency of iron chelation. Areas covered: The diagnosis requires careful clinical assessment and appropriate laboratory testing. Its management is more complex compared to other 'classical' causes of hypogonadism because of multiple associated disorders (cardiac, hepatic and endocrine) and other contributing factors basically iron overload and iron toxicity. Expert commentary: Early recognition and treatment of hypogonadism in TM patients is most important to prevent late complications and to enhance the chances of parenthood. The goal of management is to restore deficient glandular function. If fertility is the issue and the testis is under-stimulated because of gonadotropin deficiency, it is possible to induce or restore spermatogenesis with exogenous gonadotropins in some patients. Assisted reproductive techniques may supplementary help to overcome previously untreatable causes of male infertility. These positive achievements should encourage health care providers to pay closer attention to the reproductive health of TM patients. This would involve the collaboration of clinicians caring for thalassemia with endocrinologists and specialists in assisted reproductive technologies.

Abstract
Male infertility in β-thalassemia patients is typically considered to be the consequence of iron deposition in the endocrine glands. Adult male patients with β-thalassemia, on regular blood transfusions, are prone to developing acquired hypogonadism. The aim of this study was to evaluate the fertility indicators in male patients with β-thalassemia major and intermedia. In this study we evaluated testicular volume, semen parameters and serum FSH, LH, and Testosterone concentrations in 62 male patients in reproductive age, with major and intermedia thalassemia, at a tertiary care hospital in Tehran, Iran. The range of serum ferritin level in our patients was from 182 to 11053 ng/mL (mean 2067 ng/mL). The mean concentration of sperm was 61.04 million per milliliter. The mean volume of right and left testes was 11.4 cc and 11.7 cc, respectively. Those patients who had lower testicular volumes significantly had lower sperm concentration, lower percents of motile and also lower percents of normal morphologic sperms (p = 0.04). The frequency of hypogonadism was significantly higher in patients whose testicular volume was lower (p = 0.02). Hypogonadism and hypothyroidism were seen in 22.6% and 17.7% of patients, respectively. Patients with hypogonadism had significantly lower ejaculate volume, lower sperm concentration, lower percents of motile and progressively motile sperms and also lower percents of normal morphologic sperms (p = 0.001). This study suggests that in thalassemic men, concentrations of serum testosterone, LH, FSH has significant correlation with sperm parameters and testicular volume.

Abstract
Alpha-thalassemia occurs with high frenquency in China. Four common α-globin gene deletion mutations (-SEA, -α3.7, and -α4.2, Haemoglobin Constant Spring (CS) mutation) were identified in Chinese patients. Individuals with alpha-thalassemia syndrome are more often of children. However report on endocrinal complications in children with alpha thalassemia in China are still absent. The present study aimed to investigate the impact of genotype on endocrinal complications in Chinese children. Association analysis between genotype and endocrinal compliaction development was conducted on 200 patients with 200 healthy controls. Hypogonadism was found to be the most prominent endocrinal complications (84.0%) leading to the growth retardation, hypogonadism, diabetes mellitus, hypothyroidism and hypoparathyroidism whose incidence were significantly higher in pateints. (αCSα/-SEA) was the main genotype of Alpha thalassemia identified in the patients (37.5%), and patients with the (-α4.2/-SEA) genotype had a higher prevalence of hypogonadism, diabetes mellitus and hypoparathyroidism (P = 0.001, P = 0.001, P < 0.001, respectively).

Abstract
Advances in treatment of thalassemia have led to the aging of thalassemic patients, and consequently concern about successful reproductive outcome is augmented. Although women with thalassemia intermedia only were considered competent of achieving pregnancy, case series reveal the willingness of both thalassemia major and thalassemia intermedia women to have a family. Pregnancy in general is characterized by dynamic multiple-system changes and increased susceptibility to oxidative stress, while homozygous, transfusion-dependent, β-thalassemia patients manifest cardiac, hepatic, endocrine, and metabolic disorders attributable to chronic anoxia and iron overload and thalassemia intermedia, usually nontransfused, is associated with augmented risk of thromboembolic events. Pregnancy in thalassemia should be considered a high risk for both mother and fetus, and favorable outcomes are the result of continuous preconception, antenatal, and postpartum assessment and management by a team of thalassemia experts.

Abstract
AIM Chronic iron overload resulting from frequent transfusions, poor compliance to efficient chelation therapy and chronic liver disease is basically responsible for the most severe complications of thalassemia major (TM). Before conventional treatment, TM was entirely childhood disease with a very short survival. Today, survival improved to 40-50 years and becomes a prevalent disease of adulthood and in the near future it will be one of senility. Furthermore, clinical phenotype of TM is changing with age and appearance of severe complications from the heart and endocrine glands that require special health care from well-informed specialists. OBJECTIVES The aims of our study were to: (1) Imprint the clinical profile of long-lived TM patients; (2) evaluate retrospectively the cumulative incidence of endocrine diseases; (3) identify potential risk factors; and (4) orient the physicians in the modified clinical phenotype and the relative patients' health needs. DESIGN A retrospective cross-sectional study followed from childhood to adulthood by the same physician in a tertiary thalassemia clinic. PARTICIPANTS Forty-three long-lived TM patients (mean age: 50.3 ± 10.8 years; range: 45.8-59.5 years; 23 females) were studied. PATIENTS AND METHODS An extensive medical history, with detailed clinical and laboratory data, endocrine complications, and current treatments, was obtained. RESULTS The data indicate that 88.4% of adult TM patients suffered from at least one endocrine complication. The majority of patients developed endocrine complications in the second decade of life when serum ferritin level was very high (12/23 TM female and 8/20 TM male patients, the serum ferritin levels at the diagnosis were above 5.000 ng/ml). CONCLUSIONS These data underline that endocrine and bone complications in adult TM patients are highly prevalent and necessitate close monitoring, treatment, and follow-up. Physicians' strategies to optimize chelation therapy include identifying patients who are at risk for developing organ damage, developing chelation plans, promoting compliance, and educating patients. Several clinical aspects remain to be elucidated such as growth and impairment of glucose tolerance in relation to hepatitis C virus infection. Furthermore, affordable worldwide-established long-term treatment protocols for hypogonadism and osteoporosis are needed.

Abstract
INTRODUCTION It is well known that the older generation of adult TM patients has a higher incidence of morbidities and co-morbidities. At present, little information is available on adult TM patients with multiple endocrine complications (MEC). The main objectives of this longitudinal retrospective survey were: 1) to establish the incidence and progression of MEC (3 or more) in TM patients; 2) to compare the clinical, laboratory and imaging data to a sex and age-matched group of TM patients without MEC; 3) to assess the influence of iron overload represented by serum ferritin (peak and mean annual value at the last endocrine observation). PATIENTS AND METHODS The study was started in January 1974 and was completed by the same physician at the end of December 2015. The registry database of the regularly followed TM patients from diagnosis included 145 adults (> 18 years). All TM patients were of Italian ethnic origin. Eleven out of 145 patients (7.5 %) developed MEC. Twenty-four other patients (12 females and 12 males) had a normal endocrine function (16.5 %) and served as controls. RESULTS In our survey, four important, relevant aspects emerged in the MEC group. These included the late age at the start of chelation therapy with desferrioxamine mesylate (DFO); the higher serum ferritin peak (8521.8 ± 5958.9 vs 3575.2 ± 1801.4 ng/ml); the upper proportion of splenectomized (81.8 % vs. 28.5%) patients and poor compliance registered mainly during the peripubertal and pubertal age (72.7 % vs.16.6 %) in TM patients developing MEC versus those without endocrine complications. Furthermore, a negative correlation was observed in all TM patients between LIC and final height (r: -0.424; p = 0.031). CONCLUSIONS Our study supports the view that simultaneous involvement of more than one endocrine gland is not uncommon (7.5 %). It mainly occurred in TM patients who started chelation therapy with DFO late in life and who had irregular/poor compliance to treatment. Therefore, prevention of the endocrine complications through adopting early and regular chelation therapy appears mandatory for improving the quality of life and psychological outcome of these patients. When diagnosing and managing patients with MEC, it is of paramount importance that the multidisciplinary team have excellent knowledge relating to these complications. In ideal circumstances an endocrinologist with experience of TM will form part of the regular multidisciplinary team caring for such patients.
