Abstract Background Beta-thalassemia patients still suffer from many complications. Transfused patients may develop complications related to iron overload including growth retardation and failure or delay of sexual maturation, cardiac involvement (dilated cardiomyopathy or rarely arrhythmia), liver (fibrosis and cirrhosis), endocrine glands (diabetes mellitus, hypogonadism, insufficiency of parathyroid, thyroid, pituitary and less commonly, adrenal glands). Purpose The present study was undertaken to evaluate the role of Carotid artery intima media thickness (CIMT) measurement as an early detector of premature atherosclerosis in beta-thalassemia children and early adolescents and its relation to biochemical risk factors as iron overload and lipid profile. Patients and Method Twenty-two β-thalassemia major (TM), 8 β-thalassemia intermedia (TI) with confirmed diagnosis of beta-thalassemia (major and intermedia) proved by clinical and laboratory investigations, frequent blood transfusion, chelation therapy with their age ranging from 10 to18 years old and 30 age-and sex matched healthy controls were included. Lipid profile (by colorimetric assay), serum ferritin, and CIMT measurements using high-resolution B-mode ultrasonography were estimated. Results CIMT of thalassemic patients (major and intermedia) was highly significantly increased compared to controls with no significant difference between β-thalassemia major and β thalassemia intermedia groups could be detected. CIMT was positively correlated with serum ferritin, TG, Total cholesterol level in both diseased groups and LDL level in B-TM group only. This provides a good evidence of the presence of premature atherosclerosis in vascular-free TM and TI patients and its relation to increased body iron and dyslipidemia. Conclusion Carotid artery intima media thickness represented a simple, accurate and non-invasive method for early detection of premature atherosclerosis which started early in β- thalassemia patients This study identified a relationship between body iron status, dyslipidemia and increased carotid IMT..

The Relationship

Background: Iron overload is caused early progression of atherosclerosis in beta thalassemia patients due to regular repeated blood transfusion. MRI T2* is a gold standard non-invasive method for detecting hepatic and cardiac iron overload. The aim of this study was the comparison of carotid intima media thickness (CIMT) in the patients and healthy control groups with Doppler ultrasound for early diagnosis of atherogenesis. Another purpose was to assess the relationship between CIMT and iron overload among patients. Materials and methods: This cross-sectional study was performed on twenty patients referred to the Sarvar clinic and twenty age- and sex-matched control group. The CIMT was measured with Color Doppler ultrasound in both groups. Then, MRI T2* results, demographic, and therapeutic information were extracted from their documents. Results: CIMT was insignificantly higher in the patients compared to the control group. For example, it was 0.49 ± 0.05 vs. 0.45 ± 0.03 (p = 0.009) for the right common carotid artery (RCCA) and 0.48 ± 0.06 vs. 0.46 ± 0.04 (p = 0.17) for the left common carotid artery (LCCA). There was no strong relationship between CIMT and age (p = 0.09 for RCCA, p = 0.00 for LCCA), sex, chelation type (for example, p = 0.51 for RCCA with Desferal and p = 0.91 for LCCA with Desferal), age at diagnosis, age at the beginning on transfusion (p = 0.49 for RCCA, p = 0.20 for LCCA), age at the start of chelator (p = 0.74 for RCCA, p = 0.78 for LCCA), and hepatic and cardiac iron overload. Conclusion: Preventive and curative methods should be planned to cease its progression. Furthermore, early initiation of chelator drugs with better efficacy and compliance may reverse the hepatotoxic and adverse myocardial effects of excessive iron.

Introduction: Intima-media thickness (IMT) measurement of the common carotid artery (CCA) is considered as useful indicator of carotid atherosclerosis. Early detection of atherosclerosis and its associated risk factors is important to prevent stroke and heart diseases. The aim of the present study was to investigate which risk factors are better determinants of subclinical atherosclerosis, measured by common carotidartery intima media thickness (CCA-IMT).Methods: A total of 74 subjects were randomly selected in this cross – sectional study. Information on the patient’s medical history and laboratory fi ndings were obtained from their clinical records. Risk factors relevant to this study were age, gender, cigarette smoking status, diabetes, hypertension and dyslipidemia. Ultrasound scanning of carotid arteries was performed with a 7,5 MHz linear array transducer (GE Voluson730 pro). The highest value of six common carotid artery measurements was taken as the fi nal IMT. Increased CCA-IMT was defi ned when it was > 1 mm.Results: Our data demonstrated higher CCA-IMT values in male patients compared with female patients. Increased CCA-IMT was the most closely related to age (P<0.001), followed by systolic blood pressure (P=0.001), diastolic blood pressure (P=0.003) and glucose blood level (P=0.048).Conclusion: Age, gender and hypertension are the most important risk factors in development of carotid atherosclerosis. Early detection of atherosclerosis among high-risk populations is important in order to prevent stroke and heart diseases, which are leading causes of death worldwide.

Introduction and Aim: Increased carotid artery intima media thickness (CIMT) has been linked to the development of cardiovascular disease (CVD). CVD is a major cause of mortality and morbidity in India. Increased CIMT has been documented in Hypertension (HT), thus putting them at a higher risk of CVD. Early identification and awareness of risk factors leading to increased morbidity and mortality could help in reducing its incidence. The aim of the study was to measure CIMTin prehypertensive Indian population.   Materials and Methods:In this analytical observational study, common carotid artery IMT was measured using B mode ultrasonography in 46 individuals having blood pressure in the prehypertensive range and 46 individuals with normal blood pressure. Cardiovascular risk factors like body mass index(BMI),fasting blood glucose (FBS), and lipid profile, which are known to influence CIMT,were also assessed and compared between the two groups.   Results:CIMT was significantly higher in prehypertensives as compared to subjects having normal blood pressure. BMI, FBS, and lipid profile was found to be comparable between the two groups.   Conclusions:The presence of increased CIMT in prehypertensives as compared to controls indicates an increased risk of adverse cardiovascular events.

Background: It is well-known that cigarette smoke contains chemical substances, including nicotine and carbon monoxide, which can have harmful effects on cardiovascular function. Objectives: This study aimed to investigate and compare lipid levels and carotid artery intima-media thickness (CAIMT) among neonates born to smoking and nonsmoking mothers. Methods: This study was conducted on 40 term neonates (over 37 weeks of gestation) within the age range of 0 - 30 days born to smoking mothers (study group) and 34 term neonates born to nonsmoking mothers (control group). Both groups were assessed prospectively for triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and CAIMT. Results: There was no difference in the mean age of mothers between control and study groups (29.0 ± 4.5 vs. 29.3 ± 5.7 years; P = 0.31). The CAIMT was observed as similar between the groups (0.35 ± 0.05 vs. 0.36 ± 0.05 mm in control and study groups, respectively; P = 0.665). Although HDL-C levels were significantly lower in the study group (48.5 ± 16.2 vs. 39.1 ± 17.8 mg/dL; P = 0.021), no difference was observed in LDL-C, TC, and TG levels between the two groups. Conclusions: Based on the results, there were no differences in CAIMT and lipid profile other than low HDL levels between term neonates born to smoking mothers and neonates born to nonsmoking mothers. Atherosclerosis is a disease in which numerous factors play a role in the formation beginning in the fetal period and emerging with clinical findings in advanced age; therefore, it is required to perform further studies with longer follow-up and larger sample size to confirm the present study findings.
