Beta Thalassemia

BACKGROUND: Iron deficiency anemia (IDA) and b-thalassemia minor (BTM) are the two most common causes of microcytic anemia, and although these conditions do not share many symptoms, differential diagnosis by blood tests is a time-consuming and expensive process. CBC can be used to diagnose anemia, but without advanced techniques, it cannot differentiate between iron deficiency anemia and BTM. This makes the differential diagnosis of IDA and BTM costly, as it requires advanced techniques to differentiate between the two conditions...

BACKGROUND: Sickle cell disease (SCD) comprises a heterogeneous group of inherited hemolytic disorders that increases the risk of maternal and perinatal complications due to chronic systemic inflammatory response, endothelial damage and vaso-occlusion. The contribution of genotypes to the severity of outcomes during pregnancy is not completely established. METHODS: A retrospective study of medical charts was performed to compare maternal and perinatal outcomes in Hb SS, Hb SC disease and sickle-beta thalassemia (Hb Sβ) pregnancies followed at a high-risk antenatal care unit over a 6-year period...

INTRODUCTION:  The prevalence of COVID-19 is slightly lower, and its mortality is higher in beta-thalassemia patients than in the general population. We evaluated the impact of COVID-19 in terms of incidence, clinical course, management, and specific antibody response to vaccination in a cohort of patients with beta-thalassemia major. METHODS:  We retrospectively enrolled all transfusion-dependent beta-thalassemia major patients attending the Thalassemia Day Care Center of the University Hospital of Sassari, Italy, from March 1, 2020, to May 31, 2021...

BACKGROUND: Cardiac injury caused by iron overload is the leading cause of mortality and morbidity in patients with beta-thalassemia, owing to frequent blood transfusion, increased iron overload, and blood hemolysis. OBJECTIVE: This research aimed to assess several novel cardiac biomarkers in the blood samples of children and adult patients with beta-thalassemia major (βTM), along with their respective control groups. These biomarkers included endothelin 1 (ET-1), N-terminal pro-brain natriuretic peptide (NT-proBNP), atrial natriuretic peptide (ANP), growth differentiation factor-15 (GDF-15), and renalase (RNLS)...

BACKGROUND: Congenital diseases are still an important medical, social, and economic problem all over the world. In North Cyprus, in addition to other reasons, early prenatal diagnostic measures are undertaken to prevent births with thalassemia major, a locally widespread genetic disease. AIM: This study aims to evaluate the results of prenatal invasive diagnostic tests performed in a private obstetrics clinic in Northern Cyprus and show the diagnosis process of thalassemia and chromosomal anomalies...

The +33 C>G variant [NM_000518.5(HBB):c.-18C>G] in the 5' untranslated region (UTR) of the β-globin gene is described in the literature as both mild and silent, while it causes a phenotype of thalassemia intermedia in the presence of a severe β-thalassemia allele. Despite its potential clinical significance, the determination of its pathogenicity according to established standards requires a greater number of published cases and co-segregation evidence than what is currently available. The present study provides an extensive phenotypic characterization of +33 C>G using 26 heterozygous and 11 compound heterozygous novel cases detected in Cyprus and employs computational predictors (CADD, RegulomeDB) to better understand its impact on clinical severity...

Hemoglobin (Hb) disorders are among the most common monogenic diseases affecting nearly 7% of the world population. Among various Hb disorders, approximately 1.5% of the world population carries β -thalassemia ( β -Thal), affecting 40,000 newborns every year. Early screening and a timely diagnosis are essential for β -thalassemia patients for the prevention and management of later clinical complications. However, in Africa, Southern Europe, the Middle East, and Southeast Asia, where β -thalassemia is most prevalent, the diagnosis and screening for β -thalassemia are still challenging due to the cost and logistical burden of laboratory diagnostic tests...

BACKGROUND: In pediatric transfusion-dependent thalassemia (TDT) patients, we evaluated the prevalence, pattern, and clinical associations of pancreatic siderosis and the changes in pancreatic iron levels and their association with baseline and changes in total body iron balance. PROCEDURE: We considered 86 pediatric TDT patients consecutively enrolled in the Extension-Myocardial Iron Overload in Thalassemia Network. Iron overload (IO) was quantified by R2* magnetic resonance imaging (MRI)...

A 57-year-old male had abdominal pain and distension for 6-7 months with a palpable swelling in the right lumbar region. Contrast-enhanced computed tomography abdomen showed a large heterogeneous lesion with fat density measuring 22 cm ´ 16.5 cm in the right suprarenal region. Laparotomy was done which showed an encapsulated mass measuring 21 cm ´ 14 cm ´ 5 cm. Cut section revealed yellowish areas admixed with hemorrhage and large areas of necrosis. Microscopy revealed adrenal myelolipoma. The patient was found to have sickling positive...

STUDY QUESTION: Does a matrix-free culture system supplemented with neurotrophic factor 4 (NT4) improve human in vitro follicular development and meiotic maturation, ultimately resulting in fertilizable oocytes? SUMMARY ANSWER: NT4 supplementation of in vitro culture significantly enhances the growth, steroid hormone production, and maturity potential of human secondary follicles derived from fresh ovarian medulla (from post- and pre-pubertal patients), thereby yielding fertilizable oocytes...

INTRODUCTION: Beta thalassemia and hemoglobin (HbE)-related hemoglobinopathies are common public health problems in developing countries. High-performance liquid chromatography (HPLC) is currently the diagnostic test of choice for carrier detection, but it is costly. Hence, some initial screening and complementary tests are required, which can be affordable. AIMS: To find out the distribution of different red blood cell (RBC) indices in beta thalassemia trait (BTT) and HbE-related hemoglobinopathies and to determine their significance as screening tests to distinguish between these hemoglobinopathies...

OBJECTIVE: We aimed to determine the effects of fetal hemoglobin induction therapy in restricting or even reversing the cephalometric changes associated with beta thalassemia. MATERIALS AND METHODS: In this comparative observational study, 90 participants were equally divided into three groups: a control group; patients with thalassemia major receiving blood transfusion (BT group); and patients receiving induction therapy (i.e., hydroxyl urea (5-10 mg/kg/day) or as much as 20 mg/kg/day) and thalidomide (2-10 mg/kg/day) along with blood transfusion (IT group)...

Thalassemia is a hereditary autosomal recessive disorder that is distinguished by a diminished rate of hemoglobin (Hb) synthesis arising from an anomaly in the synthesis of α or β globin chains. Classical symptoms of β-thalassemia are frequently observed in patients who present late for blood transfusion (BT), which is typical among South Asian countries in light of their limited resources. This case report is an uncommon instance of a typical occurrence that has been infrequently reported in the South Asian region...

OBJECTIVES: Hepatic Veno occlusive disease (VOD), also known as sinusoidal obstruction syndrome (VOD/SOS), is a post-transplant life threatening complication. In this study, we aimed to discuss the incidence, management and outcome of VOD in post allogenic transplant patients of beta thalassemia major (BTM). METHODS: A prospective study was conducted in Armed Forces Bone Marrow Transplant Center, between 2001-2022. A total of 385 fully Human Leucocyte Antigen (HLA) matched BTM patients, with Ursodeoxycholic acid for prophylaxis, were included in the study...

OBJECTIVES: Newborn screening (NBS) for sickle cell disease (SCD) requires a robust, high-throughput method to detect hemoglobin S (HbS). Screening for SCD is performed by qualitative methods, such as isoelectric focusing (IEF), and both qualitative and quantitative methods such as high performance liquid chromatography (HPLC), capillary electrophoresis (CE), and tandem mass spectrometry (MS/MS). All these methods detect HbS, as well as low-level or absent HbA, and also other variants of hemoglobin...

BACKGROUND: Fetal hemoglobin (HbF) has been reported to be associated with disease severity and treatment response to HbF-inducing therapies like Hydroxyurea and thalidomide in patients suffering from transfusion-dependent beta-thalassemia (TDT). However, the role of hemoglobin A2 (HbA2) remains less clear in TDT, therefore this study aims to determine the impact of both HbF and HbA2 levels on disease severity and treatment response. METHODOLOGY: A prospective observational study was conducted at the Peshawar Institute of Medical Sciences and Fatimid Foundation Peshawar from May 2023 to October 2023...
