In this study, DNA was extracted then PCR was performed. Twelve overlapping fragments covering β-globin gene, have been generated by PCR.A total of 47 alterations have been recognized in β-globin gene. These alterations composed of: deletions, insertion or substitutions as follows:- one mutation identified on the 1st segment; three alterations on 2nd fragment; two alterations on 3rd segment; seven alterations on 4th segment; three substitution on 5th fragment; two changes on 6th fragment; five alterations on 7th fragment; seven substitution changes on 8th fragment; two heterozygous substitution changes on 9th fra...

CONCLUSIONS: Currently, there is no high-quality evidence to support or challenge the continued use of hydroxyurea for managing people with transfusion-dependent β-thalassaemia. Multicentre, randomised controlled trials (compared to placebo or other available treatment, i.e. blood transfusion and iron chelation) are needed in order to assess the efficacy and safety of hydroxyurea for reducing the need for blood transfusion, for maintaining or improving mean haemoglobin levels, as well as for determining its cost-effectiveness.

Authors: Eleutério RMN, Nascimento FO, Araújo TG, Castro MF, Filho TPA, Filho PAM, Eleutério J, Elias DBD, Lemes RPG Abstract Background: Sickle cell anaemia (SCA) is the most prevalent monogenic disease in Brazil. In SCA, haemoglobin S (HbS) is formed, which modifies red blood cell morphology. Intravascular haemolysis occurs, in which free Hb and free radicals degrade nitric oxide (NO) and release arginase, which reduces arginine levels. Because arginine is a substrate for NO formation, this decrease leads to reduced NO (vasodilator) synthesis. SCA treatment uses hydroxyurea (HU) to maintain h...

AbstractAsymmetric dimethylarginine (ADMA) level may play a role in the pathogenesis of cerebrovascular stroke in Children with Sickle Cell Anemia (SCA). To assess the plasma level of ADMA in children with SCA and its correlation to cerebral blood flow. This is a cross sectional study was carried out on 30 children with homozygous SCA under follow up in the Out Patients Clinic, Pediatric Department at Tanta University Hospital and 30 healthy children as a control group. Both groups had undergone the following investigations: Complete blood count, lactate dehydrogenase enzyme, and plasma level of ADMA by a commercial ADMA E...

A cutting-edge clinical trial made a breakthrough in its effort to cure sickle cell anemia. The painful genetic disease affects about 100,000 Americans every year, mostly African Americans. On "60 Minutes," Dr. Jon LaPook followed Jenelle Stephenson for more than a year as she underwent an innovative kind of gene therapy at the National Institutes of Health. The therapy uses HIV to treat patients, but the virus is weakened, so it cannot cause AIDS. LaPook, who watched his report Sunday night with four sickle cell anemia patients, and Stephenson join "CBS This Morning" to discuss the remarkable trial results.

Funding Opportunity RFA-HL-20-009 from the NIH Guide for Grants and Contracts. This funding opportunity announcement will supportprojectsto enhance the availability and delivery of safe blood to be used for transfusion in patients from low or lower-middle income countries (LLMICs) in Sub-Saharan Africa (SSA). For example, ensuring that children with malaria or sickle cell disease and pregnant women who suffer from obstetric hemorrhage have access to safe transfusion therapies is of high programmatic interest. BLOODSAFE will support projects that develop and test feasible, effective and sustainable strategies to increase t...

Authors: Niccoli Asabella A, Altini C, Nappi AG, Lavelli V, Ferrari C, Marzullo A, Loiodice A, Rubini G Abstract Sickle cell disease (SCD) is the best known haemoglobinopathy, caused by a mutation substituting valina for glutamic acid at position 6 of the beta-globin chain of adult hemoglobin A, resulting in hemoglobin S (HbS). The homozygous HbS disease (HbSS), an autosomal recessive disorder, is the most common form and the Mediterranean area, along with sub-Saharian African and India, have the highest prevalence (1%-15%). In particular, Sicily with a prevalence of 2%-5%, is among the most interested regions. How...

AbstractPurpose of ReviewSickle cell anemia is a multiorgan disease with acute and chronic complications. Involvement of the central nervous system (CNS) is associated with increased mortality and morbidity. This review highlights the broad spectrum of neurological complications seen in patients with sickle cell disease.Recent FindingsIncreasing recognition of neurological complications has led to improved diagnostic and treatment options throughout the years. Neurologic complications in sickle cell disease include silent cerebral ischemia, ischemic/hemorrhagic stroke, moyamoya syndrome, posterior reversible encephalopathy...
