Background Thyroid gland dysfunction and echocardiographic cardiac abnormalities are well-documented in patients with transfusion dependent beta-thalassemia major (β-TM). Aim This cross-sectional analytic study was conducted to investigate left ventricle (LV) diastolic and systolic function using pulsed Doppler (PD) and tissue Doppler (TD) echocardiography and correlate that with serum level thyroid stimulating hormone in patients with β-TM. Methods The study was conducted on patients with β-TM (n = 110, age 15.9 ± 8.9 years) and compared with a control group (n = 109, age 15.8 ± 8.9 years). In all participants, echocardiographic indices of PD and TD were performed and blood samples were withdrawn for measuring the serum level of TSH, free T4, and ferritin. A linear regression analysis was performed on TSH level as the dependent variable and serum ferritin as independent. Stepwise multiple regression analysis was used to determine the odds ratio of different biochemical and echo variables on the risk of developing hypothyroidism. Results Patients with β-TM compared with controls had thicker LV septal wall index (0.65 ± 0.26 vs. 0.44 ± 0.21 cm/M2, P < 0.001), posterior wall index (0.65 ± 0.23 vs. 0.43 ± 0.21 cm/m2, P < 0.01) and larger LVEDD index (4.35 ± 0.69 vs.3.88 ± 0.153 mm/m2, P < 0.001). In addition, β-TM patients had higher transmitral E wave velocity (E) (70.81 ± 10.13 vs. 57.53 ± 10.13 cm/s, P = 0.02) and E/A ratio (1.54 ± 0.18 vs. 1.23 ± 0.17, P < 0.01) and shorter deceleration time (DT) (170.53 ± 13.3 vs. 210.50 ± 19.20 m sec, P < 0.01). Furthermore, the ratio of transmitral E wave velocity to the tissue Doppler E wave at the basal septal mitral annulus (E/Em) was significantly higher in the β-TM group (19.68 ± 2.81 vs. 13.86 ± 1.41, P < 0.05). The tissue Doppler systolic wave (Sm) velocity and the early diastolic wave (Em) were significantly lower in the β-TM group compared with controls with Sm, 4.82 ± 1.2 vs. 6.22 ± 2.1 mm/sec, P < 0.05 and (Em), 3.51 ± 2.7 vs. 4.12 ± 2.5 mm/sec. P < 0.05, respectively). The tricuspid valve velocity was significantly higher in β-TM patients compared with controls 2.85 ± 0.56 vs. 1.743 ± 0.47 m sec, respectively, P < 0.01). The prevalence of subclinical hypothyroidism in patients with β-TM was 15.4%, with significantly higher mean serum TSH compared with controls (6.78 ± 1.5 vs. 3.10 ± 1.02 μIU/mL, P < 0.01) and positively correlated with the serum ferritin level ( r = 0.34, P = 0.014). On multiple regression analysis, the LV mass, LVEF%, and E/A ratio were not positive predictors of hypothyroidism in patients with β-TM. Conclusion We conclude that patients with β-TM had a high prevalence of subclinical hypothyroidism of 15.4%. Thyroid stimulating hormone was significantly high and positively correlated with the serum ferritin level. Echo cardiographic pulsed Doppler showed a restrictive LV diastolic pattern suggestive of severe diastolic dysfunction with preserved left ventricle systolic function.

Background Thalassemia is a major public health problem inIndonesia. Cardiac diseases remain as the main cause of death inthese patients due to iron overload. Although the T2* magneticresonance imaging has been considered as the gold standard forassessing cardiac iron overload but it has limited availability.The tissue doppler imaging (TDI) echocardiography, a fairly newand easy method that is suggested, can detect early abnormalmyocardial iron overload.Objective To assess myocardial systolic and diastolic functionof thalassemic patients using TDI and examine their correlationwith serum ferritin level.Methods A cross􀁌sectional study was conducted from January toMarch 2011 at the Harapan Kita Women and Children Hospital.We performed clinical examination, serum ferritin level, as wellas conventional and tissue doppler echocardiography on allsubjects.Results We included 34 regularly􀁌tranfused patients, of which17 were boys. The mean age of the subjects was 11.6 (SD 4.7years, range 2.6 􀁌 20 years). Mean pulse rate and blood pressurewere within normal range. Hemoglobin level at inclusion rangedfrom 5.8 to 6 g/dL. Almost all patients did not receive regularchelation therapy. Median serum ferritin level was 6275 ng/mL(range 2151 - 17,646 ng/mL). Conventional echocardiographyshowed normal systolic function, but some diastolic dysfunctionswere found including E wave abnormalites in 4 patients, A waveabnormalites in 3, and E/A ratio abnormalites found in 3. TheTDI showed decreased systolic function (Sa wave abnormality) in9 patients and diastolic dysfunctions (Ea wave abnormality in 11patients and Aa wave abnormaly in 2). No abnormality was foundin Ea/Aa and ElEa ratios. There was a weak negative correlationbetween ferritin level and Sa wave and Ea wave respectively anda moderately negative correlation between ferritin level and Ea/Aa ratio. There was no correlation between serum ferritin andAa wave or ElEa ratio.Conclusion TDI identifies a greater number of patients Mthsystolic and diastolic myocardial dysfunction than was revealedby conventional echocardiography. There was a weak negativecorrelation between serum ferritin to Sa wave and Ea wave, and amoderately negative correlation between ferritin and Ea/Aa ratio.There was no correlation between serum ferritin and Aa wave orElEa ratio.

Patients with transfusion dependent thalassemia major is often associated with iron overload. Proper use of iron chelators to treat iron overload requires an accurate measurement of iron levels. Magnetic resonance T2-star (T2* MRI) is the preferred method to measure iron level in the liver andthe heart. The goal of our study was to see if there is an association exists between serum ferritin level and T2* MRI results in patients with beta thalassemia major.This study was done in Al-Diwaniya Thalassemia center,Maternity and children teaching hospital,Iraq. During the period from 1st of January to 31st of October. Fifty eight patients with a diagnosis of beta thalassemia major were enrolled in the study. They were older than five years old,transfusion dependent and on chelation therapy. Hepatic and Myocardial T2*MRI and the mean serum ferritin levels were measured during the study period for all patients.There is a significant correlation was observed between serum ferritin level and cardiac T2*MRI (p=0.018 ). also a significant correlation was observed between serum ferritin and hepatic T2*MRI (p=0.02). Neither cardiac T2* MRI nor hepatic T2* MRI show any correlation with the mean age.our study also showa positive correlation between the patients withcardiac T2* MRI and the development of diabetes mellitus in contrast to hepatic T2* MRI in which there is no any correlation. Hypothyroidism was observedno correlation with either cardiac or hepatic T2* MRI.Our results showed a positiveassociation between hepatic, cardiac T2*MRI and serum ferritin levels.

Background: Thalassemia major is an inherited haemoglobin disorder resulting in chronic haemolytic anaemia. Patients with beta thalassemia major are maintained on continuous blood transfusion regimens resulting in iron overload that adversely affects both the structure and function of the heart and other vital organs which can be easily prevented with iron chelating therapy. The aim of the study was to detect left ventricular dysfunction at an early stage so that early effective intervention can be done.Methods: A total of 50 patients with beta thalassemia were included in the study by non randomized qualitative purposive sampling from July 2013 to June 2014. Their total body iron status was be assessed by doing serum ferritin level. Left ventricular systolic and diastolic function was assessed by echocardiographyResults: Cardiac dysfunction was present in 11 patients with high incidence in patients with low pre-transfusional haemoglobin group (p=0.4) and in patients having high serum ferritin level (p=0.02). Systolic cardiac dysfunction was present in 7(14%) of patients and diastolic dysfunction was present in 4(8%) of patients. There was a weak but significant correlation between left ventricular ejection fraction and serum ferritin concentration (r=-0.22; p=0.03). Only few (8%) patients had diastolic dysfunction.Conclusion: Patients with beta thalassaemia on an adequate transfusion showed an abnormal left ventricular systolic function. In early stage of disease diastolic function was normal but after repeated transfusion there were impaired relaxation indicating diastolic dysfunction. These findings seem mainly to be related to chronic anaemia and serum ferritin levelCardiovasc. j. 2016; 9(1): 31-35

Background: Beta-Thalassemia is a genetic disorder which is associated with a lot of complications. Frequent blood transfusions result in increased iron deposition in various tissues leading to dysfunction of many vital organs. Endocrine disorders constitute a major part of such complications increasing the morbidity of thalassemia manifold in the affected patients. Methods:  This is a descriptive cross sectional study carried out in 100 diagnosed patients of beta- thalassemia major who had visited the OPD/IPD of Subharti Medical College & affiliated Hospitals, Meerut for routine blood transfusion or for any other complication. Patients were clinically examined and investigated for presence of one or more endocrine disorders on their routine appointments. Results: Endocrine disorders were detected in a total of 82 patients. Diabetes mellitus was detected in 12% patients, hypothyroidism in 36% patients and delayed puberty was found in 72% patients. Mean serum ferritin level was found to be 5831.0±2860.5 ng/ml in beta-thalassemia Major patients, while it was in normal range in control subjects. Conclusion: Research concluded with finding of Delayed puberty (72%), Hypothyroidism (36%) and diabetes mellitus as (12%) in beta thalassemia patients who were on regular blood transfusion therapy.  Iron overload as serum ferritin level was found to be highly raised in all study case. On the basis of our study we recommend that early detection and management protocols for these endocrinopathies may improve the life prospects of beta-thalassemia Major patients.

Introduction: β-Thalassemia major (β-TM) is a genetic haemoglobin disorderwhich is relatively common in some geographical areas. β-TM is characterized by severe anaemia,which needs a continuous blood transfusion regimen starting from the first months of life toprolong survival. Objectives: To compare mean reduction in serum ferritin level with deferasiroxand desferrioxamine when used as an iron chelator in multi-transfused beta thalassemia major.Study design: Randomized controlled trial. Setting: Thalassemia clinic, The Children’s Hospitaland The Institute of Child Health, Lahore. Duration of Study with Dates: Study was carried outover a period of nine months from 28-06-2015 to 27-03-2016. Subjects and Methods: A totalof 100 patients (50 patients in each group). The patients were randomly allocated into twogroups using random numbers stable. Group-A received Deferasirox and group-B receivedDesferrioxamine. Results: Mean age of the patients was 7.42±4.13 and 7.87±4.13 in group-Aand B, respectively. Regarding sex distribution, 26 patients (52.0%) in group-A and 28 patients(56.0%) in group-B were male while 24 patients (48.0%) in group-A and 22 patients (44.0%) ingroup-B were female. Reduction from baseline in group-A was 783.60±413.66 ng/ml and ingroup-B 552.80±155.45 ng/ml (P<0.001) There was more reduction in group-A. In group-Abaseline serum ferritin level was 2495.00±1259.10 ng/ml and at 9 month 1712.00±1019.36 ng/ml (P<0.001). Similarly in group-B baseline serum ferritin level was 2422.80±910.43 ng/ml andat 9 month 1883±862.72 ng/ml (P<0.001). Conclusion: In conclusion, deferasirox was moreeffective in terms of reduction in serum ferritin level when compared with desferrioxamine inmulti-transfused beta thalassemia major patients.

Background: Beta-thalassemia major is a type of inherited blood disease that results in variable outcomes such as severe anemia due to haemoglobin chains. Recurrent and lifelong blood transfusions as a treatment in beta-thalassemia major disease lead to iron deposition in various organs and cause the failure of multiple organs. Failure of affected organs leads to Body mass index (BMI) abnormality. This study aimed to evaluate the association between BMI and serum ferritin level as a marker for iron overload. Materials and Methods: A cross-sectional study designed and conducted with total number of 740 paediatrics, with mean age about 14.2±8.7 years old and with beta-thalassemia major requiring recurrent blood transfusion. Patient information, including demographics, serum ferritin level and percentage of BMI, was recorded and analysed by SPSS 25.0 and the statistical significant level, considered as 0.05.    Results: A total number of 740 paediatrics with beta-thalassemia major disease (mean age about 14.2±8.7 years) were included to study to examine the association between serum ferritin level and their BMI.  The total mean serum level of ferritin calculated about 3326 ± 3859 Nanogram/mililitter (ng/ml). Totally, 447 (60.4%) case of them had BMI percentile less than 5%, 274 (37.02%), 16 (2.16%) and 3 (0.4%) had BMI percentile 5%-85%, 85%-95% and more than 95%. There was no relation between gender and serum ferritin levels. The relationship between age and BMI has been positive (P=0.002). Finally, it resulted that there was a negative relationship between the BMI percentile and mean serum ferritin levels in paediatrics with beta-thalassemia major (P=0.031). Conclusion: Frequent Blood transfusion is associated with elevated serum ferritin level in paediatrics with beta-thalassemia major disease and experiencing lower percentiles of BMI in these patients.

BACKGROUND: Zinc is one of the most important minerals incorporated in the enzymes of the human body. Zinc may be deficient in patients with the β-thalassemia major with possible adverse outcomes. AIM: The purpose of this study was to assess the serum zinc status in β-thalassemia major patients in Duhok city. PATIENTS, MATERIAL, AND METHODS: In this case–control study, 70 children with β-thalassemia major (2–12 years) of both genders were enrolled and were matched with 70 apparently healthy children for age and sex. A venous blood sample was obtained from each child for the measurement of serum zinc and serum ferritin levels at Jin Center in Duhok City between January 1 and June 30, 2017. RESULTS: The mean serum zinc in the thalassemia patients (74.79 [±25.14] μg/dl) was significantly lower compared to the control group (93.61 [±15.12] μg/dl), (p = 0.0001). The serum zinc was not significantly different in thalassemia patients in terms of age, disease onset, gender, height, weight, body mass index, amount of blood transfusion, and type of chelation. There was a statistically significant correlation between serum zinc levels with a serum ferritin level of patients. CONCLUSION: The study showed that thalassemia patients have significantly lower serum levels of zinc with no relation to medical factors.
