Abstract
OBJECTIVE To explore the effects of a multidisciplinary team (MDT) continuous care model on psychological behavior and quality of life in children with β-thalassemia major (β-TM). METHODS A retrospective study was conducted on 90 children with β-TM who were hospitalized in the Department of Pediatrics, Affiliated Hospital of Youjiang Medical University for Nationalities from October 2021 to May 2022. According to nursing methods, the children were divided into a routine group and an experimental group, with 45 cases in each group. The routine group was intervened with routine nursing approaches, and the experimental group was intervened with the MDT continuous nursing mode on the basis of the control group. The psychological behavior [Positive and Negative Affect Scale for Children (PANAS-C)], quality of life (QoL) [Pediatric Quality of Life Inventory TM (PedsQLTM)] and satisfaction were compared between the two groups before and 6 months after intervention. The hemoglobin level and ferritin level of children after 3 months and 6 months of intervention were measured. The occurrence of complications and nursing satisfaction were recorded. The prognostic factors were further analyzed. RESULTS After the intervention, the positive emotion score, QoL score, hemoglobin level, satisfaction score in the experimental group were all higher than those in the conventional group, and the negative emotion score and ferritin level in the experimental group were all lower than those in the conventional group (all P < 0.05). The results of Cox analysis showed that the use of iron-removing drugs and arrhythmia/heart rate failure were risk factors affecting the prognosis of children with β-TM, while the MDT continuous nursing mode was a protective factor (all P < 0.05). CONCLUSION The MDT continuous care model can effectively promote mental health in children with β-TM, improve their quality of life, medical satisfaction, ameliorate the degree of anemia in children, reduce the incidence of complications and improve the prognosis; thus, it is worthy of wide clinical application.

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
INTRODUCTION Hypogonadism is one of the most frequent complications in transfusion-dependent thalassemia patients and early recognition and treatment is the core element in restoring impaired gonadal function. Despite the high burden of disease, relevant studies are scarcely addressing the gonadal function of such patients in Bangladesh. The pattern of gonadal function in transfusion-dependent thalassemia patients must be characterized before planning a generalized management plan. Moreover, since iron overload is a key reason behind hypogonadism in thalassemia patients, investigating the role of serum ferritin level as a diagnostic tool for hypongadism was also an aim of this study. METHODS This cross-sectional study was conducted at the Department of Transfusion Medicine of the Bangabandhu Sheikh Mujib Medical University. According to the inclusion and exclusion criteria, a total of 94 patients were enrolled in this study. A detailed history and thorough clinical examination were carried out in each patient and recorded using a pretested structured questionnaire. In addition, the laboratory assessment of serum ferritin, luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone and estradiol in serum were also performed. The data were analyzed using the STATA (v.16). RESULTS The mean age of the patients with transfusion-dependent thalassemia was 18.81 ± 4.65 (SD), with 53.3% of the patients being male. The overall prevalence of hypogonadism was 35.11%, 18.1% being normogonadotropic, 11.7% being hypogonadotropic and 5.3% being hypergonadotropic. The serum ferritin level was significantly higher (p < 0.001) in patients with hypogonadism (Eugonadal: 2,174.79 (± 749.12) ng/ml; Hypogonadal: 3,572.59 (± 1,199.49) ng/ml). The area under the receiver operating characteristic (ROC) curve of serum ferritin was high (0.83) and the p-value was highly significant (< 0.001). CONCLUSION Therefore, the serum ferritin level and gonadal hormone analysis of transfusion-dependent thalassemia patients can be considered a screening tool for assessing gonadal function and early detection and prevention of hypogonadism.

Abstract
Introduction Cardiomyopathy due to myocardial iron deposition is the leading cause of death in transfusion- dependent beta-thalassemia major (β-TM) patients. Although cardiac T2* magnetic resonance imaging (MRI) can be used for the early detection of cardiac iron level before the onset of symptoms associated with iron overload, this expensive method is not widely available in many hospitals. Frontal QRS-T angle is a novel marker of myocardial repolarization and is associated with adverse cardiac outcomes. We aimed to investigate the relationship between cardiac iron load and f(QRS-T) angle in patients with β-TM. Methods The study included 95 β-TM patients. Cardiac T2* values under 20 were considered to indicate cardiac iron overload. The patients were divided into two groups according to the presence or absence of cardiac involvement. Laboratory and electrocardiography parameters, including frontal plane QRS-T angle, were compared between the two groups. Results Cardiac involvement was detected in 33 (34%) patients. Multivariate analysis showed that frontal QRS-T angle independently predicted cardiac involvement (p < 0.001). An f(QRS-T) angle of ≥ 24.5° had a sensitivity of 78.8% and a specificity of 79% in detecting the presence of cardiac involvement. In addition, a negative correlation was found between cardiac T2* MRI value and f(QRS-T) angle. Conclusions A widening f(QRS-T) angle could be considered a surrogate marker of MRI T2* to detect cardiac iron overload. Therefore, calculating the f(QRS-T) angle in thalassemia patients is an inexpensive and simple method for detecting the presence of cardiac involvement, especially when cardiac T2* values cannot be determined or monitored.

Abstract
Background Iron overload and cardiac dysfunctions are common complications in patients with thalassemia major (TM). Different imaging methods can be used to detect ventricular dysfunction in these patients. In this study, we aim to understand the value of tissue Doppler imaging (TDI) in the detection of myocardial dysfunction in patients with TM who have been diagnosed with iron overload using cardiovascular magnetic resonance CMRT2*. Methods In this cross-sectional study, fifty patients with TM diagnosed with iron overload who had no clinical signs and symptoms of cardiac dysfunction were chosen as a case group. The control group included fifty sex- and age-matched healthy participants without a history of cardiac and hematological diseases. TDI, pulsed wave Doppler (PWD), and standard echocardiography were performed to study the left ventricular function, and cardiac iron overload assessed by CMRT2*. Then, the patients with TM were divided into two subgroups and compared with each other. Group 1a includes individuals with T2* value <20 ms and group 1b T2* value >20 ms. Results There was no significant difference between the standard echocardiography results and PWD parameters of the case and control groups; however, CMRT2* findings and TDI parameters were different between the case and control groups. CMRT2* findings also were not correlated with PWD parameters. In group 1a, CMRT2* findings were negatively correlated with age, E', A', early deceleration time, and isovolumetric relaxation time and positively correlated with E/E' ratio. Finally, PWD and TDI parameters were significantly different between the two subgroups. Conclusion TDI can detect ventricular systolic and diastolic dysfunctions in earlier stages among patients with iron overload. It seems that TDI could detect abnormalities more accurately, and it is better to consider subclinical cardiac dysfunction in patients with even CMRT2* value of more than 20 ms and reevaluate them in future.

Abstract
Beta-thalassemia major is characterized by a genetic deficiency in synthesis of beta-globin chains, resulting in reduced levels of functional hemoglobin. It is characterized by anemia, hepatosplenomegaly, and iron overload due to repeated blood transfusion. Hematopoietic stem cell transplantation is currently the only known curative treatment. We present a case of a 10-year-old girl with beta-thalassemia major who was successfully cured with allogeneic booster umbilical cord blood (UCB) transplantation with outcome data after 3 years of transplantation, in India. Postdiagnosis, she was on regular once-a-month blood transfusion until the age of 10 years, with no improvement. No serious adverse events occurred in the patient post-UCB transplantation. Chronic graft versus host disease was limited and was managed by medicines. Signs of primary graft rejection were also not seen.

Abstract
BACKGROUND Ineffective erythropoiesis (IE) is the most prominent feature of transfusion-dependent beta-thalassemia (TDT), which leads to extramedullary hemopoiesis. The rejection rate in allogeneic hematopoietic stem cell transplantation (HSCT) is high in heavily transfused patients with TDT accompanied by prominent IE. Therefore, a pretransplantation treatment bridging to HSCT is often used to reduce allosensitization and IE. Ruxolitinib is a JAK-1/JAK-2 inhibitor and has showed its efficacy in suppressing IE and the immune system. A previously published study on RUX in adult patients with TDT has revealed that this treatment significantly reduces spleen size and is well tolerated. PROCEDURE Ten patients (5-14 years old) with TDT and an enlarged spleen were enrolled. The dose of ruxolitinib was adjusted for age: for patients <11 years: 40-100 mg/m2 total daily dose and for patients >11 years: 20-30 mg/m2 total daily dose. HSCT was performed in 8 of 10 patients. RESULTS After the first 3 months of ruxolitinib therapy, spleen volume decreased in 9 of 10 cases by 9.1%-67.5% (M = 35.4%) compared with the initial size (P = 0.003). The adverse events of ruxolitinib (infectious complications, moderate thrombocytopenia, and headache) were successfully managed by reducing the dose. The outcomes of HSCT were favorable in seven of eight cases. CONCLUSION Ruxolitinib is promising as a short-term pre-HSCT treatment for pediatric patients with TDT and pronounced IE.

Abstract
This study was conducted to evaluate the cardiac perfusion and function of patients with beta-thalassemia major (TM) using99mTc-MIBI cardiac gated single-photon-emission computed tomography (SPECT) and to compare the obtained indices with echocardiographic and hematological parameters. Patients with TM who were referred for regular blood transfusion and periodic checkup were included in this study. A questionnaire containing demographic and medical data was provided for all patients by an expert pediatrician. All of the patients were on Desferal chelation therapy and none of them had clinical signs of heart failure. Myocardial gated perfusion SPECT, echocardiography, and complete blood tests were performed for each patient. In total, 24 patients including 14 men (58.3%) and 10 women (41.7%) aged 15-36 years with a mean age of 24.3 ± 6.5 years' old were enrolled in this study. Myocardial perfusion scan (MPS) was normal in all patients. The mean value of the measured left ventricular ejection fraction (LVEF) was 58.88 ± 13.45%. There was no significant association between measured LVEF on scan and echocardiography (P > 0.05). In terms of hematological results, there was a significant association between the hemoglobin and ferritin level and the amount of blood transfusion (P = 0.02 and P= 0.00, respectively). According to the results of myocardial perfusion imaging (MPI), cardiac perfusion and LVEF were within normal limits in all asymptomatic patients. In the absence of any perfusion abnormality, the use of MPI in patients with asymptomatic beta-TM is not recommended for diagnosing myocardial ischemia.

Abstract
Beta-thalassemia major is a chronic disorder characterised by severe anemia. This patient with beta-thalassemia major is the first magnetic resonance (MR) angiographic case for symmetric mirror aneurysms of the extracranial internal carotid arteries. For diagnosis of vascular complications requires angiographic procedures such as catheter angiography, computed tomography angiography, MR angiography, or Doppler ultrasonography. Time-of-flight MR angiography is a non-invasive useful technique in diagnosis of the aneurysmatic patients.

Abstract
OBJECTIVE/BACKGROUND The purpose of this study was to evaluate serum cardiac troponin I and serum N-terminal (NT) pro-brain natriuretic peptide (pro-BNP) levels and the utility of tissue Doppler imaging in assessing cardiovascular changes following left ventricular (LV) dysfunction in children with beta-thalassemia major (β-TM). In children with β-TM who depend on regular blood transfusion, cardiac iron toxicity is a common serious complication. The most common cause of death among these patients is congestive heart failure. METHODS This is a cross-sectional study which included 50 patients with β-TM and 50 healthy controls. Tissue Doppler imaging was performed and levels of serum ferritin, cardiac troponin I, and NT pro-BNP were estimated for all included patients. RESULTS Serum NT pro-BNP and cardiac troponin (cTnI) showed a significant increase in patients with β-TM (p < .001). In patients with β-TM, LV dimensions (LV end systolic diameter) and (LV end diastolic diameter) were large (p < .01); LV mass (p < .01), E wave, and E/A ratio (p < .01) were high (p < .05); and deceleration time was short (p < .05). Besides, transmitral ratio (E/Em) (p < .05) and tricuspid valve velocity were higher (p < .05), and early diastolic velocity (Em) (p < .05) and systolic wave velocity (Sm) were lower in patients with β-TM (p < .05). A significant positive correlation was detected between the pro-BNP and E wave (r = 0.558, p < .001), E/A ratio (r = 0.403, p < .001), E/Em ratio (r = 0.576, p < .001), and ferritin (r = 0.545, p < .001). CONCLUSION Pulsed wave tissue Doppler imaging and NT pro-BNP had a significant role in the estimation of ventricular dysfunction in children with β-TM.

Abstract
In Tunisia, beta-thalassemia major is a real public health problem. A study carried out of patients affected shows that for them, this chronic haemoglobinopathy is a disability hampering their physical activities, their social integration, their academic results and their emotional life.

Abstract
This study aimed to assess left (LA) and right atrial (RA) function in patients with beta-thalassaemia major. Thirty-eight patients (19 males) aged 34.5 ± 10.7 years and 43 (18 males) controls aged 30.3 ± 12.6 years (p = 0.12) were studied. The maximum RA and LA areas were measured using two-dimensional planimetry, while atrial and ventricular strain and strain rates were quantified using speckle-tracking echocardiography. Compared with controls, patients had significantly reduced LA and RA peak positive strain and total strain, and LA strain rate during ventricular systole and at atrial contraction (all p < 0.05). The LA and RA strain parameters were significantly associated (all p < 0.05). The maximum LA (10.2 ± 1.6 cm2/m2 vs. 8.6 ± 1.3 cm2/m2, p < 0.001) and RA (9.2 ± 1.2 cm2/m2 vs. 7.5 ± 1.3 cm2/m2, p < 0.001) areas were significantly greater in patients than controls. The LV and RV strain and early strain rates were similar between patients and controls (all p > 0.05). Four patients with significant myocardial iron overload had larger LA area (p < 0.001) than those without. Functional and structural remodeling of both the right and left atria occurs in patients with beta-thalassaemia major, even in the absence of ventricular diastolic dysfunction.

Abstract
BACKGROUND Regular blood transfusion therapy still remains the cornerstone in the management of β-thalassemia. Although recommendations are clear for patients with β-thalassemia major, uniform transfusion guidelines are lacking for patients with hemoglobin E β-thalassemia. In this study, we aim to describe the adequacy, trends, and determinants of blood transfusion therapy in a large cohort of pediatric patients with β-thalassemia major and hemoglobin E β-thalassemia. METHODS/PROCEDURE This cross-sectional study was performed among all regularly transfused patents with β-thalassemia aged 2 to 18 years attending three large thalassemia centers in Sri Lanka. Data were collected using an interviewer-administered questionnaire, perusal of clinical records, and physical examination of patients by trained doctors. RESULTS A total of 328 patients (male 47%) were recruited; 83% had β-thalassemia major, whereas 16% had hemoglobin E β-thalassemia. Sixty-one percent of patients had low pretransfusion hemoglobin levels (< 9.0 g/dL) despite receiving high transfusion volumes (> 200 mL/kg/year) by a majority (56%). Median pretransfusion hemoglobin was significantly lower in patients with hemoglobin E β-thalassemia compared with β-thalassemia major (P < 0.001); however, there was no difference in requirement for high transfusion volumes over 200 mL/kg/year in both groups (P = 0.14). Hepatomegaly and splenomegaly were more common in hemoglobin E β-thalassemia and were associated with lower pretransfusion hemoglobin. Transfusion requirements were higher among patients with hepatitis C and in those who are underweight. CONCLUSIONS Over 60% of regularly transfused patients with β-thalassemia have low pretransfusion hemoglobin levels despite receiving large transfusion volumes. Patients with hemoglobin E β-thalassemia are undertransfused and specific recommendations should be developed to guide transfusions in these patients.

Abstract
PURPOSE The main purpose of this meta-analysis was to evaluate the impact of beta-thalassemia major (BTM) on the health-related quality of life as assessed by the medical outcomes short-form-36 questionnaire (SF-36). METHODS A systematic literature search was performed on Cochrane library, Web of Science, Scopus, Science Direct, ProQues, Medline/PubMed, Scholar Google until March 17, 2017 to obtain eligible studies. A fixed effect model was applied to summarize the scores of each domain. The radar chart was used to compare the scores of BTM patients with other health conditions. Spearman's correlation analysis and meta-regression were used to explore the related factors. RESULTS 26 studies were included in this study, which were all reliable to summarize the scores of the SF36. Pooled mean scores of the physical health domains ranged from 52.74 to 74.5, with the GH and PF domains being the lowest and the highest, respectively. Further, the pooled mean scores of the mental health domains varied between 59.6 and 71.11, with the (MH-VT) and SF domains being the maximum and the minimum, respectively. Patients with BTM had a substantially compromised HRQoL in comparison with the general population. CONCLUSION BTM could adversely affect the HRQoL of patients. Measuring HRQoL should be considered as an essential part of the overall assessment of health status of BTM patients, which would provide valuable clues for improving the management of disease and making decisions on the treatment.

Abstract
BACKGROUND Hematopoietic stem cell transplantation (HSCT) is currently the only curative treatment for thalassemia majorTM. Graft rejection (GR) and graft-versus-host disease (GVHD) are the primary obstacles to a successful outcome. METHODS We conducted a retrospective study of HSCT in 29 children (median age at transplantation: 6 years) with Beta-thalassemia (β-TM) after the combined infusion of granulocyte colony-stimulating factor-primed bone marrow (G-BM) and cord blood (CB) from the human leukocyte antigen (HLA)-identical sibling donors. We also compared the outcomes of the co-transplanted children with those of children with β-TM who received G-BM alone from an HLA-identical sibling donor (n = 26). RESULTS Compared to the G-BM transplant (G-BMT) recipients, those who received a co-transplant had a lower incidence of grade ≥II acute (17.24 vs. 30.7%, p = 0.047) and limited chronic (0 vs.15.4%, p = 0.022) GVHD as well as a lower incidence of GR (0 vs. 7.7%, p = 0.132). Neutrophil recovery time was faster in the co-transplant group (18.5 vs. 21 days, p = 0.04). All the patients were monitored until December 31, 2016; the median follow-up time was 74 months<unterline>,</unterline> and the 5-year thalassemia-free survival rate was 89.7% in the co-transplant group and 84.6% in the G-BMT-alone group (p = 0.590). CONCLUSIONS A combined CB and G-BM graft from an HLA-identical sibling donor is an effective treatment option for TM in children, with less acute and chronic GVHD.

Abstract
Patients with beta-thalassemia major (BTM) suffer from fatigue, poor physical fitness, muscle weakness, lethargy, and cardiac complications which are related to an energy crisis. Carnitine and acylcarnitine derivatives play important roles in fatty acid oxidation, and deregulation of carnitine and acylcarnitine metabolism may lead to an energy crisis. The present study aimed to investigate carnitine and acylcarnitine metabolites to gain an insight into the pathophysiology of BTM. Dried blood spots of 45 patients with BTM and 96 age-matched healthy controls were analyzed for free carnitine and 24 acylcarnitines by using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Although medium chain acylcarnitine levels were similar in the patients with BTM and healthy controls, free carnitine, short chain acylcarnitines, long chain acylcarnitines, and total acylcarnitine levels were significantly lower in patients with BTM than in the healthy controls (P < 0.05). Moreover, an impaired fatty acid oxidation rate was observed in the patients with BTM, as manifested by decreased fatty acid oxidation indicator ratios, namely C2/C0 and (C2 + C3)/C0. Furthermore, an increase in the C0/(C16 + C18) ratio indicated reduced carnitine palmitoyltransferase-1 (CPT-1) activity in the patients with BTM compared with that in the healthy controls. Thus, a low level of free carnitine and acylcarnitines together with impaired CPT-1 activity contribute to energy crisis-related complications in the patients with BTM.

Abstract
Traditional echocardiography is unable to detect neither the early stages of iron overload cardiomyopathy nor myocardial iron deposition. The aim of the study is to determine myocardial systolic strain indices in thalassemia major (TM), and assess their relationship with T2*, a cardiac magnetic resonance index of the severity of cardiac iron overload. 55 TM cases with recent cardiac magnetic resonance (CMR-T2*) underwent speckle tracking analysis to assess regional myocardial strains and rotation. The results were compared with a normal control group (n = 20), and were subsequently analyzed on the basis of the CMR-T2* values. Two TM groups were studied: TM with significant cardiac iron overload ("low" T2*, ≤20 ms; n = 21), and TM with normal T2* values ("normal" T2*, >20 ms; n = 34). TM patients show significant, uniform decrease in circumferential and radial strain (P < 0.05), and a remarkable reduction in end-systolic rotation, both global, and for all segments (P < 0.001). No significant differences were found between the low- and the normal T2* group either in regional strains and rotation or in standard echocardiographic and CMR parameters. Spearman's correlation coefficient shows no significant correlation between myocardial strains, rotation and cardiac T2* values. In conclusion, our results are in accordance with recent evidence that myocardial iron overload is not the only mechanism underlying iron cardiomyopathy in TM. Strain imaging can predict subclinical myocardial dysfunction irrespective of CMR-T2* values, although it cannot replace CMR-T2* in assessing cardiac iron overload. Finally, it might be useful to appropriately time cardioactive treatment.

Abstract
OBJECTIVE The aim of the study was to investigate the role of osteoprotegerin (OPG)/RANK/RANKL variants in left ventricular hypertrophy (LVH) and diastolic dysfunction in thalassemia major patients MATERIALS AND METHOD: One hundred and five beta-thalassemia patients who were older than 10 years of age were enrolled for the study. Two-dimensional and M-mode echocardiography analysis was done in all patients. Genotyping for OPG [rs2073617 (950 T>C), rs2073618 (1181G>C)], RANK [(rs1805034(+34694 C>T), rs12458117 (+34901 G>A) and rs75404003 (+35966insdelC)], and RANKL (rs2277438, rs9594782) variants was done using the PCR-RFLP method. Serum OPG levels were estimated by ELISA. RESULTS Mean age of patients was 16.36 ± 5.08 years. LVH and diastolic dysfunction was present in 33 (31.4%) and 24 (22.8%) patients, respectively. Thalassemia patients having minor allele of OPG rs2073618, RANK rs75404003 and RANKL rs9594782 SNPs were at high risk for LVH as suggested by high odds ratio of 2.470, 3.783, and 2.148, respectively; however, none of the SNPs tested were statistically significantly associated after applying Bonferroni corrections for multiple testing adjustment. No significant association of any SNP with diastolic dysfunction was observed. Serum OPG levels were found significantly higher in thalassemia patients with diastolic dysfunction (P = 0.006). CONCLUSION OPG rs2073618, RANK rs75404003, and RANKL rs9594782 SNPs may predispose LVH in thalassemia patients. Patients with diastolic dysfunction showed increased levels of serum OPG.

Abstract
BACKGROUND Paroxysmal atrial tachyarrhythmias frequently occur in beta-thalassemia major (β-TM) patients. The aim of the current study was to evaluate the atrial electromechanical delay (AEMD) in a large β-TM population with normal cardiac function and its relationship to atrial fibrillation (AF) onset. METHODS Eighty β-TM patients (44 men, 36 women), with a mean age of 36.2 ± 11.1 years, and 80 healthy subjects used as controls, matched for age and gender, were studied for the occurrence of AF during a 5-year follow-up, through 30-day external loop recorder (ELR) monitoring performed every 6 months. Intra-AEMD and inter-AEMD of both atria were measured through tissue Doppler echocardiography. P-wave dispersion (PD) was carefully measured using 12-lead electrocardiogram (ECG). RESULTS Compared to the healthy control group, the β-TM patients showed a statistically significant increase in inter-AEMD, intra-left AEMD, maximum P-wave duration, and PD. Dividing the β-TM group into two subgroups (patients with or without AF), the inter-AEMD, intra-left AEMD, maximum P-wave duration, and PD were significantly higher in the subgroup with AF compared to the subgroup without AF. There were significant good correlations of intra-left AEMD and inter-AEMD with PD. A cut-off value of 40.1 ms for intra-left AEMD had a sensitivity of 76.2% and a specificity of 97.5% in identifying β-TM patients with AF risk. A cut-off value of 44.8 ms for inter-AEMD had a sensitivity of 81.2% and a specificity of 98.7% in identifying this category of patients. CONCLUSIONS Our results showed that the echocardiographic atrial electromechanical delay indices (intra-left and inter-AEMD) and the PD were significantly increased in β-TM subjects with normal cardiac function. PD and AEMD represent non-invasive, inexpensive, useful, and simple parameters to assess the AF risk in β-TM patients.

Abstract
Deferasirox is a standard treatment for chronic transfusional iron overload. Adverse effects of deferasirox have been reported in large prospective studies. We report two cases of monozygotic twins manifesting with proximal muscular atrophy and weakness under deferasirox. Discontinuation of deferasirox resulted in symptom improvement and ultimately in complete remission five months after successful haematopoietic stem cell transplantation. Broad diagnostic work-up could not bring evidence of another aetiology of muscular weakness. Iron overload or beta thalassemia itself as a cause is considered unlikely in our patients because the chronological coincidence of muscular symptoms was contra-directional to serum ferritin levels and significant clinical improvement was observed promptly after cessation of deferasirox even before transplantation. These observations suggest that the development of muscular weakness in patients on deferasirox should be recognised as a possible adverse effect of the drug.

Abstract
BACKGROUND Thalassemia is one of the most common hereditary disorders and Beta-thalassemia major is its severe form. The present study is concerned with the analysis of liver function, thyroid function and estimation of critical serum ions as well as hematological characteristics in beta-thalassemia patients and controls. SUBJECTS AND METHODS The study included 54 patients with beta-thalassemia major and 54 healthy individuals matched by sex and age. The activity of Alanine transaminase (ALT), Alkaline phosphatase (ALP) and Aspartate transaminase (AST) were assessed in order to evaluate the liver function. Serum content of iron (Fe), calcium (Ca), magnesium (Mg), sodium (Na) and potassium (K) were also estimated. Tri iodothyronine (T3), Thyroxin (T4) and Thyroid-stimulating hormone (TSH) levels were assessed in order to evaluate the thyroid function. Hemoglobin (Hb), ferritin, hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration(MCHC), total iron binding capacity (TIBC) and creatinine level were also measured. RESULTS Significantly, higher ALT (P< 0.001), AST (P< 0.05), ALP (P< 0.001) activities and lower creatinine (P< 0.001) level in beta-thalassemia patients were found in comparison to healthy individuals. Lower serum level of calcium (P< 0.05), magnesium (P< 0.05) and higher level of iron (P> 0.05), sodium (P> 0.05) and potassium (P > 0.05) have been found in patients in comparison to healthy individuals. Hematological parameters like Hb (P< 0.001), ferritin (P< 0.05), HCT (P< 0.001), MCV (P< 0.05) and MCH (P< 0.05) have been significantly reduced in patients except MCHC (P> 0.05). No significant difference was observed in thyroid function between patients and control group. CONCLUSIONS Our study demonstrates that beta-thalassemia patients and controls have difference in liver function, thyroid function, serum contents of ions and hematological characteristics.

Abstract
OBJECTIVES The occurrence of cardiac iron deposition is one of the late effect of iron over load which causes cardiovascular disease (CVD) in patients who are affected by beta-thalassemia major. Evaluation of some cardiovascular risk factors plays a crucial role in prediction and prevention of CVD. SUBJECTS AND METHODS This study consisted of 70 young adult subjects with beta-thalassemia major (beta-TM) (aged <30 years) and 71 age- and sex-matched healthy subjects as control group in the range of 20-30 years. Hematological and biochemical laboratory parameters including apolipoprotein (Apo)A1 and ApoB, oxidative stress biomarker pro-oxidant-antioxidant balance (PAB), homocysteine, serum high-sensitivity C-reactive protein (hs-CRP), and lipid profile were evaluated. RESULTS ApoA1, ApoB, lipid profiles, and homocysteine were significantly decreased in patients group (P < 0.001); however, very low-density lipoprotein and also mean corpuscular hemoglobin concentration (P > 0.05) were different. Some elements included ferritin (P < 0.001), PAB (P < 0.001), and ApoB/apoA1 ratio (P < 0.05) statistically increased in patients, whereas hs-CRP (P > 0.05) was not significantly different in study groups. Exception of high-density lipoprotein (P > 0.05), other lipid profiles, and apoB had a negative meaningful correlation with PAB (P < 0.05). Likewise, apoA1, apoB, apoB/A1 ratio with apoB and homocysteine showed a strong correlation (P < 0.05). We did not find a slight correlation between apoB/A1 ratio in the company of oxidative stress marker PAB (r = -0.366; P = 0.086). We found a statistical correlation between apoB/A1 and homocysteine (P < 0.05). DISCUSSION Higher level of some risk factors like PAB values, apoB/A1 ratio concentration, and lipid profiles is able to involve in the prognostic pathological consequences in patients with beta-thalassemia major. Even so, they contribute toward the gradual development of CVD.

Abstract
AIM This study reports evaluated prevalence of CD in patients with Beta-thalassemia major. BACKGROUND Celiac Disease (CD) is an autoimmune disorder triggered by ingestion of gluten in genetically predisposed individuals. PATIENTS AND METHODS In this case-control study in a period of 3 years, which was performed on 620 children in two groups of Beta-thalassemia major patients (n=200) and control (n=420), serum tissue transglutamianse (tTG) IgA levels were measured. The two groups were compared together in terms of tTG IgA levels, and p<0.05 was considered significant. RESULTS The means of serum tTG IgA levels in patients with Beta-thalassemia major and control groups were 28.81±68.44 and 6.94±6.68 U/mL, respectively. There was a significant difference in favor of the case group (p=0.000). Body mass index in the two case and control groups had a significant difference (t=3.859, p=0.001). Belonging to each group will change the probability of having less than 20 in tTG IgA (odds=0.285) and it means that belonging to the control group has a protective role. There is only a significant association in the case of all population (r=0.102, p=0.011). Body mass index in the two case and control groups had a significant difference (t=3.859, p=0.001). CONCLUSION Probability of CD should be considered since the prevalence of CD is high in patients with and Beta-thalassemia major. Patients with thalassemia major are recommended for screening for CD.

Abstract
Down syndrome is the most common chromosomal abnormality and is frequently associated with transient myeloproliferative disorder (TMD) and leukaemias. The coinheritance of this syndrome with beta-thalassemia major is uncommon. Only two cases of coinheritance of Down syndrome with beta-thalassemia major have been published in literature. We report an infant suffering from Down syndrome who presented with severe anemia which was later attributed to beta-thalassemia major and TMD. The infant improved after blood transfusion and other supportive management. The blasts disappeared from marrow during hospital stay. In areas of high prevalence of beta-thalassemia heterozygotes, the presence of coinheritance of the mentioned condition with another congenital disorder may be common.

Abstract
BACKGROUND Understanding the possible role of visfatin in the pathogenesis of beta-thalassemia major (BTM) and its relationship with markers of endothelial function could help us to provide more effective therapeutic approaches for treatment of patients with BTM and its related complications. The aim of current study was to compare serum level of visfatin between patients with BTM and control group and determine its correlation with markers of endothelial function, intracellular adhesion molecule (ICAM) and vascular adhesion molecule (VCAM). METHODS In this case-control study, patients with BTM receiving regular blood transfusion aged 10-20 years and a group of healthy subjects were enrolled. Selected subjects examined clinically and venous blood samples obtained for visfatin, ICAM, VCAM, cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol and ferritin measurements. Mean (standard deviation) of studied laboratory measurements compared in two studied groups and the relation between visfatin and ICAM, VCAM, ferrittin, body mass index determined. RESULTS In this study 31 patients with BTM and 30 healthy controls studied. Mean of visfatin was significantly higher in patients with BTM than control group (133.9 ± 60.1 vs. 43.3 ± 27.9, P < 0.001). CONCLUSIONS The higher level of visfatin among patients with BTM indicated the possible inflammatory role of this adipocytokine in BTM. It seems that for understanding the underlying mechanisms and its relation with vascular inflammatory markers and endothelial function further studies with larger sample size is needed.

Abstract
Background: The ideal management of thalassemia involves a multidisciplinary therapeutic team approach and should be preferably done at a comprehensive thalassemia care center with all sorts of specialists and the backup of a well-equipped blood bank. However, in developing country like ours, these facilities are not available in rural set up. So, a situation where conservative therapy with regular blood transfusion is the only choice left to innumerable thalassemic children. Objective: To evaluate the existing conservative management protocol of Beta-thalassemia major patients in the setup of a subdivision level Government Hospital of rural West Bengal, India. Materials and Methods: The study was performed between December 2009 and December 2011. Beta-thalassemia major patients, registered in blood bank for moderate transfusion regimen, were taken in study. All the patients were screened for Transfusion Transmittable Infections at the time of registration and thereafter periodically every six months. Iron chelation therapy was given simultaneously with transfusion at a dose of 20 to 40 mg/kg/day for six days. The patients were advised to follow up with chelation therapy at home by daily infusion with a goal of maintaining serum ferritin level below 1000 ng/ml. Over this long period of study, the patients were periodically evaluated for complications. Results: The average blood requirement (ml/kg/year) in 1-5 years, 6-10 years, and 11-15 years were 110, 150, and 180, respectively. Incidence of Hepatitis C Virus infection in 1-5 years and 6-10 years were 1.75% and 2.08%, respectively. It is well seen that serum ferritin level increase with ascending age as does the blood consumption. Conclusion: Conservative management may be the best alternative and at times the only hope for patients in developing country like ours. However, in order to decrease the disease load, steps need to be taken to introduce preventive measures.

Abstract
Background: Children suffering from beta-thalassemia major require repeated blood transfusions which may be associated with dangers like iron overload and contraction of infections such as HIV, HCV, and HBsAg which ultimately curtail their life span. On the other hand, inadequate transfusions lead to severe anemia and general fatigue and debility. Materials and Methods: Data were obtained from 142 beta-thalassemia major patients aged 3 years or more receiving regular blood transfusions at a transfusion centre in Western India from 1 April 2009 to 30 June 2009. The clinical data and laboratory results were subsequently analyzed. Results: Of the 142 patients, 76 (53.5%) were undertransfused (mean Hb <10 gm%). 96 (67%) of the patients were taking some form of chelation therapy but out of them only 2 (2%) were adequately chelated (S. ferritin <1000 ng/ml). 5 (3.5%) of the patients were known diabetics on insulin therapy. 103 (72%) of the patients were retarded in terms of growth. The prevalence of transfusion-transmitted infections (TTIs) such as HCV, HIV, and HBsAg was respectively 45%, 2%, and 2%, with the prevalence of HCV being significantly more than the general population. The HCV prevalence showed positive correlation with the age of the patients and with the total no of blood transfusions received. As many as 15% (6 out of 40) children who were born on or after 2002 were HCV positive despite the blood they received being subjected to screening for HCV. Conclusions: The study suggests the need to step up the transfusions to achieve hemoglobin goal of 10 gm% (as per the moderate transfusion regimen) and also to institute urgent and effective chelation measures with the aim of keeping serum ferritin levels below 1000 ng/ml to avoid the systemic effects of iron overload. In addition, strict monitoring of the children for endocrinopathy and other systemic effects of iron overload should be done. Rigid implementation of quality control measures for the ELISA kits used to detect HCV in donor blood needs to be done urgently. Alternately, more sensitive and specific measures (like NAT testing) should be employed for detection of HCV. In the absence of a definitive cure accessible and available to all patients, strict implementation of the above suggested measures will go a long way in improving the quality (and quantity) of life in patients of beta-thalassemia major.
