<p>The present study evaluates carotid intimamedia thickness (CIMT) in children with β thalassemia major to assess atherosclerosis and its relation to the underlying proposed causative mechanisms <em>via</em> lipid peroxidation product malondialdehyde (MDA), oxidized lowdensity lipoproteins (LDL), total antioxidant level, and lipid profile. A cross sectional study was conducted on 62 children (31 cases and 31 controls). CIMT by high resolution ultrasound and biochemical parameters <em>i.e.</em>, total cholesterol, triglycerides, high-density lipoproteins, LDL, Oxidized LDL, lipoprotein (a), lipid peroxidation product MDA and total antioxidant were measured in enrolled subjects and compared. In our study, CIMT was significantly increased in β thalassemia major patients’ as compared to healthy controls. Mean CIMT in cases was 0.69±0.11 mm and in controls 0.51±0.07 mm. Mean oxidized LDL (EU/mL) in cases 39.3±34.4 (range 14.4 to 160) was significantly raised (P=0.02, t test) as compared to controls 23.9±13.4 (range 12 to 70). In our study we found MDA levels (nmol/mL) to be increased in β thalassemia patients as compared to controls. Mean MDA was 10.0±3.27 (4.41 to 17.48) in cases while in controls was 6.87±4.55 (1.5 to 17.9). Our study results show CIMT as an early marker of atherogenesis in β thalassemia major. Oxidative stress markers are also increased in β thalassemia major patients and lipoprotein (a) shows a positive correlation with CIMT. The present study points towards various atherogenetic mechanisms in β thalassemia major.</p><p> </p><p>本研究评价β重型地中海贫血患儿颈动脉内膜中层厚度（CIMT），以评估动脉粥样硬化，以及与潜在通过血脂过氧化反应产物丙二醛（MDA）、氧化低密度脂蛋白（LDL）、总抗氧化水平和血脂谱所提出致病机制之间的关系。 在62名儿童（31例病例和31例对照）中进行了一项横断面研究。 在入组受试者中通过高分辨率超声和生化指标（即总胆固醇、甘油三酯、高密度脂蛋白、LDL、氧化LDL，脂蛋白（a）、血脂过氧化产物MDA和总抗氧化剂）测量CIMT并进行比较。 在我们的研究中，CIMT在β重型地中海贫血患者中比健康对照组显著增加。 病例组中的平均CIMT为0.69±0.11 mm，对照组0.51±0.07 mm。病例组中平均氧化LDL（EU/mL）为39.3±34.4（从14.4到160的范围）与对照组的23.9±13.4（12至70的范围）相比显著升高（P = 0.02，t检验）。 在我们的研究中，我们发现β地中海贫血患者中的MDA水平（nmol/mL）比对照组更高。 病例组中的平均MDA为10.0±3.27（4.41至17.48），而对照组为6.87±4.55（1.5到17.9）。 我们的研究结果表明，CIMT是β重型地中海贫血动脉粥样硬化的早期标记物。 氧化应激标记物在β重型地中海贫血患者中也有增加，脂蛋白（a）显示出与CIMT呈正相关。 本研究针对β重型地中海贫血中的各种动脉粥样硬化机制。</p>

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.

Abstract Background Hypertriglyceridemia thalassemia syndrome is a rare entity with an unknown pathogenetic link. Case presentation We report a case of an 8-month-old female with thalassemia major and increased triglyceride (TG) levels. The clinical features were as in classical thalassemia except for a white discoloration of the plasma. After exclusion of familial triglyceridemia and secondary causes (hypothyroidism, nephrotic syndrome, drugs etc.), a diagnosis of hypertriglyceridemia thalassemia syndrome was made. Conclusions The high levels of TG in these patients are associated with oxidative stress and higher risk of acute pancreatitis and coronary diseases. An early recognition is thus essential. In our patient, the levels reduced after a transfusion therapy similar to previous reports.

Objective: We aimed to investigate the oxidative stress status in children with β-thalassemia major (β-TM) by measuring native thiol (SH), disulfide (SS) and total thiol (SH + SS) plasma levels. Methods: This study was carried out from November 2017 to March 2018 at the Pediatric Hematology Clinic of the Harran University Medical Faculty Hospital. Blood specimens were collected from 100 participants, including 50 β-TM patients and 50 controls, and SH, SS and SH+SS levels were detected through a newly developed method. Results: SH, SS, SH+SS levels and SS/SH ratio were markedly higher in β-TM patients than in controls. In β-TM group, SH and SH+SS levels were positively correlated with age, albumin and total bilirubin. Serum ferritin level was positively correlated with SH, SH+SS, aspartate transaminase and alanine transaminase. Conclusions: We found that the SS/SH ratio was high in patients with β-TM, which shows increased oxidative stress. This ratio may be considered as a tool for the determination of oxidative status in such patients due to easily calculate, suitable for routine use and economical.
