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.

[PMID: 37568184 PMCID: PMC10422764 DOI: 10.1186/s40359-023-01268-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 07/28/2023] [Indexed: 08/13/2023] Open
Abstract
BACKGROUND Resilience is the ability to overcome adversity in response to a potentially traumatic event. It can relieve people's discomfort and build personal capacity when facing a stressful situation such as beta thalassemia major. Resilience is a complex and multidimensional concept and is influenced by protective and risk factors. Therefore, the aims of the present study were to (1) investigate the relationship between protective (social support and hope) and risk (uncertainty and defensive coping) factors with resilience and (2) examine the mediating role of courageous coping between these protective and risk factors in resilience. METHODS This descriptive-analytical study was performed on 312 adolescents and young adults with beta-thalassemia major aged 12-24 years; they were selected using purposeful sampling from two different outpatient thalassemia clinics in the south of Iran. Data were collected in a face-to-face survey using Zimmet Multidimensional Scale of Perceived Social Support, Herth Hope, Stewart Uncertainty in Illness scale, Jalowiec Coping, and Connor-Davidson resilience Scale from April 2022 to November 2022. The collected data were analyzed using descriptive tests, Pearson correlation, and a structural equation model. RESULTS According to the main findings of mediation analysis, courageous coping partially mediated the relationship between social support and resilience [(β = 0.042; 95% BC CI (0.003, 0.131)] and fully mediated the relationship between hope and resilience [(β = 0.166; 95% BC CI (0.031, 0.348)]. In other cases, uncertainty and defensive coping had a direct and indirect effect on resilience, respectively. CONCLUSION Based on these results, health professionals and healthcare policymakers should consider this mediator in developing programs to improve resilience. Also, the use of courageous coping could modulate the effect of defensive coping on resilience. Therefore, teaching the use of courageous coping can play an important role in improving resilience.

Abstract
Background Although beta thalassemia major (BTM) patients are properly treated with blood transfusions in accompany with iron chelation therapy, they suffer from complications, such as diabetes mellitus (DM). Purpose The purpose was to detect the critical serum ferritin level and other parameters correlated with DM among adult BTM patients. Also, it was to study whether each of these parameters is associated with a certain period of age. Patients and Methods This study included 200 adult BTM patients. A cross-sectional study was carried out. Patients clinical and laboratory variables, such as ferritin levels, and fasting blood glucose (FBS) were extracted from medical records at Zagazig University Hospital, Egypt. Liver and cardiac iron contents were assessed using MRI T2* methods. Statistical analysis was performed using IBM SPSS V26.0 software package. Results The overall frequency of DM over the total sample equals 6.5%. There were no impaired fasting glucose (IFG) in the medical records. Statistical significance between serum ferritin and DM was (P = 0.014). The serum ferritin 2500 ng/mL with age group (27-<32) years-old were risk factors. The distributions of DM according to BMI were (3.5%) of class overweight. Significant association between DM and BMI was (r = 0.357, P < 0.001). Liver MRI T2* has significant correlation with serum ferritin, but cardiac MRI T2* was poorly correlated. Association between liver and cardiac MRI T2* was not found. Conclusion Age group (27-<32) years-old and ferritin >2500 ng/mL should be properly treated immediately. The serum ferritin and BMI of class "overweight" were risk factors for DM. Factors such as diet should be followed. Serum ferritin can be used for estimating liver iron content for economic factors. But cardiac MRI T2* must be performed for evaluating cardiac iron accurately.

Abstract
OBJECTIVE To determine the prevalence of short stature, delayed puberty, hypothyroidism, and diabetes mellitus in multiply transfused patients of beta thalassemia major and their correlation with serum ferritin. METHODS A descriptive observational study was conducted in a tertiary care center in Indore, Madhya Pradesh from 2014 to 2016. All children with thalassemia major of the age group 8 to 18 y attending outpatient department or admitted in ward were included in the study. Detailed clinical history, demographic data, compliance to transfusion and chelation therapy, and growth parameters were recorded. Blood samples to look for endocrinopathies and serum ferritin were assessed. Tanner staging was done to assess for delayed puberty. RESULTS Mean age of study participants (n = 50) was 15.98 ± 3.4 y. Short stature (n = 44; 88%), delayed puberty (n = 33; 71.7%), hypothyroidism (n = 6; 16%), and diabetes mellitus (n = 5; 10%) were the endocrinal abnormalities found. Mean serum ferritin level was 3122 ± 2117 ng/mL. Serum ferritin had significant positive correlation with serum TSH (thyroid stimulating hormone), fasting blood sugars, postprandial blood sugar, and delayed puberty. CONCLUSION Evaluation of endocrinopatines must be carried out in thalassemia major patients regularly by pediatricians to detect and treat endocrinal complications. Importance of chelation therapy must be emphasized frequently to parents and patients.

Abstract
Thalassemia is an inherited disease that causes the production of damaged hemoglobin chains. Patients are diagnosed with thalassemia major due to major clinical signs and deep anemia. This study aimed to examine the major thalassemia and psychosocial aspect of it, which is such an important issue, to serve as a roadmap for better handling these patients and to contribute to the literature. The method used in this study was narrative review. A literature review was conducted by searching the materials published in databases including Web of Science, PubMed, Scopus, and Google Scholar search engine from 2001 to 2020. Besides WHO website was searched. Thalassemia major damages the heart, liver, lungs and endocrine organs due to anemia and iron accumulation. In addition, the patient may experience mental and social problems due to the congenital nature of the disease and its lifelong duration. The psychosocial problems and treatment burdens of thalassemia patients are very high. There are many studies about the prevalence and physical consequences of thalassemia. However, there are not enough articles and researches describing the psychosocial effects of thalassemia on patients and what can be done about these effects. For this reason, this paper focuses on the process of thalassemia and the psychosocial problems it creates to contribute to the literature and to be a roadmap for better handling these patients.

Abstract
Background Blood transfusion is a traditional treatment for β-thalassemia (β-thal) that improves the patients' anemia and lifespan, but it may lead to iron overload in parenchymal tissue organs and endocrine glands that cause their dysfunctions as the iron regulatory system can't excrete excess iron from the bloodstream. Objective To evaluate the prevalence of iron-related complications (short stature, growth retardation, and growth hormone deficiency) in β-thalassemia major (βTM) patients. Methods We performed an electronic search in PubMed, Scopus, and Web of Sciences to evaluate the prevalence of growth hormone impairment in β-thalassemia major (βTM) patients worldwide. Qualities of eligible studies were assessed by the Joanna Briggs Institute checklist for the prevalence study. We used Comprehensive Meta-Analysis (Version 2) to calculate the event rate with 95% CIs, using a random-effects model for all analyses. Findings Seventy-four studies were included from five continents between 1978 and 2019; 70.27% (Asia), 16.21% (Europe), 6.75% (Africa), 2.70% (America), 1.35% (Oceania), and 2.70% (Multicenter). The overall mean age of the participants was about 14 years. The pooled prevalence of short stature (ST) was 48.9% (95% CI 35.3-62.6) and in male was higher than female (61.9%, 95% CI 53.4-69.7 vs. 50.9%, CI 41.8-59.9). The pooled prevalence of growth retardation (GR) was 41.1% and in male was higher than in female (51.6%, 95% CI 17.8-84 vs. 33.1%, CI 9.4-70.2). The pooled prevalence of growth hormone deficiency (GHD) was 26.6% (95% CI 16-40.8). Conclusion Our study revealed that near half of thalassemia patients suffer from growth impairments. However, regular evaluation of serum ferritin levels, close monitoring in a proper institute, suitable and acceptable treatment methods besides regular chelation therapy could significantly reduce the patients' complications.

Abstract
A retrospective evaluation of growth in 112 patients (68 males, 44 females) with Hb E (HBB: c.79G>A)/β-thalassemia (β-thal), classified as 88 transfusion-dependent thalassemia (TDT) and 24 non transfusion-dependent thalassemia (NTDT), is reported. Patients with TDT have received regular transfusions of red blood cells (RBCs) 15 mL/kg every 4 weeks to maintain pre transfusion hemoglobin (Hb) levels of at least 9.0 g/dL and were categorized according to age at initiation of regular RBC transfusion as subgroup 1, <4 years; subgroup 2, 4-10 years, and subgroup 3, >10 years. Iron chelation was initiated at the mean age of 7 years. The results revealed that patients in subgroups 1 and 2, receiving RBC transfusions at a young age (2.9 and 6.9 years, respectively), had normal prepubertal growth at enrollment and last follow-up. Patients in subgroup 3, with the lowest initial height Z-score of -2.10, were able to achieve comparable final adult height as those in subgroups 1 and 2. The mean final height of 21 males and 13 females with TDT at the ages of 18.9 and 18.7 years was 168.1 and 157.7 cm, respectively, which did not significantly differ from their midparental height and those with NTDT. Early initiation of optimal transfusion and iron chelation promoted normal prepubertal growth. However, delayed initiation of transfusion at age 12 years impaired prepubertal growth but they could achieve normal final adult height.

Abstract
To test the postulated hypothesis that splenectomy may influence the development of Hypothyroisdism (HT) in Transfused Dependent Thalassemia (TDT) young patients, basic factors known to influence the development of hypothyroidism were evaluated in 52 TDT adult patients (25 splenectomized) with HT. Precise analysis of data not only failed to disclose any statistical differences but revealed similarities, between splenectomized and non- splenectomized patients in respect to: i) the age at diagnosis of HT and ii)the ferritin levels on diagnosis and at the year of study. Interestingly a statistically higher age at diagnosis was recorded in central HT irrespective of splenectomy.

Abstract
Background Endocrinopathies are common in patients with β-thalassemia major despite parenteral iron chelation therapy with deferoxamine. Prevalence of abnormal glucose metabolism in previous studies was controversial. The aim of this study was to discuss the prevalence of abnormal glucose metabolism in β-thalassemia major based on a meta-analysis. Methods PubMed, ScienceDirect, Springerlink, Ovid, Web of Science, MEDLINE, Wanfang database, and Chinese National Knowledge Internet were searched for relevant articles. Two authors selected the articles according to the inclusion criteria and then extracted the data. The prevalence of diabetes mellitus (DM) in β-thalassemia major was defined as the primary outcome. The prevalence with the 95% confidence interval (95%CI) was used to evaluate the proportion of abnormal glucose metabolism and other endocrine disorders in patients with β-thalassemia major. Subgroup analyses were applied to explore the prevalence in different regions. Sensitivity analysis and publication bias assessment were also conducted. Results A total of 44 studies with 16605 cases were included in this analysis. Diabetes mellitus was present in 6.54% (95% CI: 5.30%-7.78%). The fixed subgroup study revealed that the region with the highest prevalence was the Middle East (prevalence= 7.90%, 95% CI: 5.75%-10.05%). The accumulated meta-analysis revealed that the prevalence of DM in β-thalassemia major was relatively steady in each year. The prevalence of impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and other endocrine disorders in β-thalassemia major was 17.21% (95% CI: 8.43%-26.00%), 12.46% (95% CI: 5.98%-18.94%), and 43.92% (95% CI: 37.94%-49.89%), respectively. Sensitivity analysis showed that the pooled results were robust; publication bias assessment revealed that there was no significant evidence that the pooled results were influenced by publication bias. Conclusion High prevalence of endocrine disorders involving abnormal glucose metabolism was detected in β-thalassemia major. Treatment and prevention measurements may be necessary to prevent growth and endocrine problems.

Abstract
BACKGROUND Thalassemia major (TM) patients eventually face many new health conditions, including endocrinopathies and low bone mineral density, usually observed in the aging general population. OBJECTIVE The aim of the current study was to evaluate the biomarkers of bone remodeling in TM patients and to compare them with both osteoporotic and healthy population, in order to investigate the new therapeutic paths. METHODS Sixty-four patients with TM (32 men and 32 women) participated in the study. The patients were evaluated with dual-energy X-ray absorptiometry (DXA) of the lumbar spine and femoral neck and with markers of bone remodeling including receptor activator of nuclear factor kappa-Β ligand (RANKL), osteoprotegerin (OPG), C-terminal telopeptide (CTX), and sclerostin. Results were compared with those from 12 postmenopausal women with osteoporosis and 12 women with normal bone mineral density. RESULTS The statistical analysis of the biochemical markers of bone metabolism revealed overall significant differences between the three groups only for RANKL and OPG/RANKL (p=0.049 and p=0.009). RANKL was higher and OPG/RANKL was lower in TM patients compared to osteoporosis group. CONCLUSION Patients with TM do not have a higher probability of suffering from osteoporosis from the general population. However, some markers of osteoclast activity differ between patients with TM and osteoporosis, indicating the possible differences in terms of anti-osteoporotic treatment. The lack of significant differences among the three groups in regards to the levels of CTX and sclerostin may indicate the potential efficacy of the current osteoporotic treatment also for TM patients.

Abstract
Diabetes of the exocrine pancreas (DEP) is a form of diabetes that occurs due to pancreatic disease. It is far more common than has been previously considered, with a recent study showing 1.8% of adults with new-onset diabetes should have been classified as DEP. The majority is misdiagnosed as type 2 diabetes mellitus (T2DM). Patients with DEP exhibit varying degrees of exocrine and endocrine dysfunction. Damage to the islet of Langerhans effects the secretion of hormones from the β, α, and pancreatic polypeptide cells; the combination of low insulin, glucagon, and pancreatic polypeptide contributes to rapid fluctuations in glucose levels. This form of "brittle diabetes" may result in the poorer glycemic control observed in patients with DEP, when compared with those with T2DM. Diabetes of the exocrine pancreas has a different natural history to other forms of diabetes; patients are more likely to require early insulin initiation compared with those with T2DM. Therefore, individuals with DEP should be advised about the symptoms of decompensated hyperglycemia, although they are less likely to develop ketoacidosis. Clinicians should screen for DEP in patients with acute or chronic pancreatitis, following pancreatic resection, or with co-existing cystic fibrosis or hemochromatosis. Incident diabetes may herald the onset of pancreatic ductal carcinoma in a small subset of patients. Once identified, patients with DEP can benefit from specific lifestyle advice, pancreatic enzyme replacement therapy, metformin treatment, appropriate insulin dosing, and monitoring. Further research is needed to establish the ideal treatment regimens to provide optimal clinical outcomes for this unique form of diabetes.

Abstract
INTRODUCTION Endocrine dysfunction due to iron overload secondary to frequent blood transfusions is a common complication in children with transfusion-dependent thalassaemia (TDT). We ascertained the prevalence of endocrine dysfunction in children with TDT seen in a hospital setting in Malaysia. METHODS We reviewed all patients with TDT who had ≥ 8 blood transfusions per year. Patients who had a history of stem cell transplantation, concurrent autoimmune diseases or were newly diagnosed to have TDT were excluded. Standard diagnostic criteria were used in the diagnosis of various endocrine dysfunctions. RESULTS Of the 82 patients with TDT, 65% had at least one endocrine dysfunction. Short stature was the commonest (40.2%), followed by pubertal disorders (14.6%), hypoparathyroidism (12.3%), vitamin D deficiency (10.1%), hypocortisolism (7.3%), diabetes mellitus (5.2%) and overt hypothyroidism (4.9%). Subclinical hypothyroidism and pre-diabetes mellitus were seen in 13.4% and 8.6% of the patients, respectively. For children aged < 10 years, the prevalence of both thyroid dysfunction and hypoparathyroidism was 9.1%. CONCLUSION Two-thirds of children with TDT experienced at least one endocrine dysfunction. Thyroid dysfunction and hypoparathyroidism may be missed if endocrine screening is only performed in children with TDT > 10 years of age. Close monitoring for endocrine dysfunction and hormonal therapy is essential to prevent long-term adverse outcomes.

Thyroid Function in Chronically Transfused Children with Beta Thalassemia Major: A Cross-Sectional Hospital Based Study. Int J Pediatr 2018; 2018:9071213. [PMID: 30305822 PMCID: PMC6165584 DOI: 10.1155/2018/9071213] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2018] [Revised: 06/22/2018] [Accepted: 08/30/2018] [Indexed: 12/04/2022] Open
Abstract
Background Thalassemia is the most common genetic disorder worldwide. Use of iron chelators has improved survival but endocrine complications have become more frequent. The frequency of hypothyroidism in Beta Thalassemia Major (BTM) children ranges from 6 to 30 %. Thyroid dysfunction mainly occurs by gland infiltration, chronic tissue hypoxia, free radical injury, and organ siderosis. Objectives (a) To evaluate the thyroid function status in chronically transfused children with BTM, in the first and second decade of life and (b) to study the influence of factors like duration and amount of blood transfusions, serum ferritin level, and iron chelation therapy on thyroid function. Methodology BTM children, 3 years old and above, on regular blood transfusions with serum ferritin > 1500 mcg/l were included in the study. Thyroid function and ferritin assessment was done using ELISA kits. Autoimmune thyroiditis was ruled out by antithyroid peroxidase and antithyroglobulin antibody testing. Results A study population of 83 children consisted of 49 boys (59%) and 34 girls (41%). 4.8% of the children had evidence of subclinical hypothyroidism. Among them two belonged to the first decade and the other two to the second decade of life. Mean TSH, FT4, and ferritin values among children with thyroid dysfunction were 6.38 ± 0.83 mIU/ml, 1.08 ± 0.45 ng/dl, and 3983.0±1698.30 ng/ml, respectively. The severity of thyroid dysfunction was statistically significantly associated with higher serum TSH values in children in the second decade of life with a p value = 0.001. No other significant correlation was found between oral chelation, amount and duration of blood transfusion, or serum ferritin levels. Conclusion Subclinical hypothyroidism was the thyroid dysfunction observed in our study. Regular blood transfusions with adequate chelation may decrease incidence of thyroid dysfunction.

Abstract
BACKGROUND Transfusion dependency determines iron overload in thalassaemia major, with devastating complications. Significant liver iron overload has been observed from early childhood and we aimed to evaluate factors that could predict liver iron overload at the first magnetic resonance imaging (MRI). MATERIALS AND METHODS All transfusion-dependent children who underwent MRI to assess iron overload were retrospectively studied. Age, weight, height, blood requirement, chelation drug and dosage, serum ferritin and liver enzymes were evaluated at three specific steps: start of transfusion regimen, start of chelation therapy, and first MRI. RESULTS Among 198 patients, 25 children met inclusion criteria. No differences were detected in all the assessed parameters at start of transfusion regimen and chelation therapy (p>0.05) between patients with good iron balance (liver iron concentration [LIC] <7 mg Fe/g dry weight [dw]) and liver iron overload (LIC >7). At the first MRI, patients with iron overload had significantly higher serum ferritin (3,080.3±1,078.5 vs 1,672.0±705.3 ng/mL; p<0.01) while patients with good iron control maintained a stable ferritin value from the start of chelation therapy but showed significantly lower height Z-score (-1.48±1.02 vs -0.36±1.55; p=0.04). Serum ferritin >1,770 ng/mL was detected as the best threshold for predicting liver iron overload at the first MRI (p=0.0003). CONCLUSION In order to prevent liver iron overload at the first MRI, children should maintain a stable level of serum ferritin below 1,770 from the start of chelation therapy. However, strict monitoring of growth is mandatory.

Abstract
Low quality of life (QOL) is a feature that has been overlooked in thalassemia major (TM) patients. Our aim was to assess QOL in school-aged TM patients in Zabol city and surrounding rural areas in southeast of Iran. The study was performed in 2014. QOL was evaluated using Pediatric Quality of Life Inventory 4 (PedsQL4) questionnaire addressing physical, emotional, social, and educational, along with psychological health in 80 TM patients. Also, 80 age-matched and sex-matched subjects without any chronic illness served as control group. Mean age of the patients was 11.7±4.1 years old. Total QOL scores was 51.4±13.3 in the patients. In comparison, mean value of total QOL score in controls was 91.1±3.3 (P<0.0001). Poor and moderate QOL were observed in 44.7% and 48.7% of the patients, respectively. Mean functioning scores for physical, emotional, social, educational, and psychological dimensions in the patients were 56.2±119, 69.6.4±23.3, 27.1±22.1, 52.3±18.1, and 48.9±11.8, respectively. The lowest level of QOL was related to the social field (81.3% with less than average score), while the highest QOL was related to the emotional aspect (58.8% with good QOL; >75 scores). Overall, female sex, poor compliance with chelation therapy, and residency in urban areas were significantly associated with poor QOL. In conclusion, providing a psychiatric health package seems to be essential for improving QOL in TM patients, especially in social field.

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
Sustained donor engraftment after allogeneic hematopoietic cell transplantation (HCT) converts to healthy donor hemoglobin synthesis and halts disease symptoms in patients with sickle cell disease and thalassemia major. A disease-free survival probability that exceeds 90% has been reported when HCT using an HLA-matched sibling donor is performed in young patients with low-risk disease or treatment-related risk factors. Alternate donor HCT and HCT in adults is performed infrequently because of a higher risk profile. Transplant-specific risks include conditioning regimen-related toxicity, graft-versus-host disease, graft rejection with marrow aplasia or disease recurrence, and infections associated with immunosuppression and delayed immune reconstitution. The magnitude of risk depends on patient age, clinical status of the underlying disease (eg, organ injury from vasculopathy and iron overload), donor source, and intensity of the conditioning regimen. These risks are commonly monitored and reported in the short term. Documenting very late outcomes is important, but these data are rarely reported because of challenges imposed by patient drop-out and insufficient resources. This report summarizes long-term follow-up results after HCT for hemoglobin disorders, identifies gaps in knowledge, and discusses opportunities for future investigations. This consensus summary will be followed by a second article detailing comprehensive long-term follow-up recommendations to aid in maintaining health in these individuals and identifying late complication risks that could facilitate interventions to improve outcomes.

Abstract
Short stature is one of the most common endocrinopathies in transfusion-dependent thalassemia (TDT). This study aimed to determine the longitudinal pattern of growth in pediatric patients with TDT and study the relationship between growth and hemoglobin level, serum ferritin level/iron overload parameters, and other clinical factors. The interval height-for-age Z-scores (HAZ) of 50 patients with TDT, of a mean age of 13.3±2.8 years, were analyzed using linear mixed model analysis. Nineteen patients (38%) had short stature with HAZ≤-2.0. The prevalence of short stature increased with age. The estimated mean HAZ decreased by 0.19 SD per year from the age of 5 years until approximately 14 years (95% confidence interval [CI], -0.22 to -0.16, P<0.001). Male sex (estimate, -0.28; 95% CI, -0.43 to -0.14; P<0.001), mean 3-year hemoglobin level ≤8 g/dL (estimate, -0.36; 95% CI, -0.53 to -0.19; P<0.001), mean 3-year ferritin level ≥1800 ng/mL (estimate, -0.44; 95% CI, -0.59 to -0.29; P<0.001), and cardiac T2* ≤20 ms (estimate, -1.05; 95% CI, -1.34 to -0.77; P<0.001) were significantly associated with short stature. In conclusion, short stature in patients with TDT is common and relates significantly with increasing age, male sex, hemoglobin level, and iron overload status.
