BACKGROUND Glutathione S-transferase gene deletions are known detoxification agents and cause oxidative damage. Due to the different pathophysiology of anemia in thalassemia and sickle cell disease, there are significant differences in the pathophysiology of iron overload and iron-related complications in these disorders. OBJECTIVE The aim of this study was to estimate the frequency of the GS...
Background: Patients with sickle cell disease suffer from various complications during their lifetime and have to adapt themselves to this chronic disease through promoting their self-management and preventing complications of the disease. Chronic disease self-management programs are a combination of strategies that increase self-efficacy and promote self-management behaviors. The present study...
Hemoglobinopathies, disorders of hemoglobin structure and production, are one of the most common monogenic disorders in humans. Glucose 6 phosphate dehydrogenase deficiency (G6PD) is an inherited enzymopathy resulting in increased oxygen stress susceptibility of red blood cells. The distributions of these genetic traits in populations living in tropical and subtropical regions where malaria has...
Background Sickle-thalassemia is an inherited hemoglobin disorder resulting from the combined heterozygosity for sicklecell and b-thalassemia genes. Myocardial iron overload in patients with sickle-thalassemia has been poorly studied; however, a report has shown no evidence of cardiac iron in a small group (n=10) of multitransfused Arab patients. The current study aims to further evaluate cardi...
results sickle cells were observed among 20% of subjects with the dilution of 1:50 and 70% of subjects with the dilution of 1:100. mean percentage of sickle red cells with dilutions of 1:50, 1:100 and 1:200 were 3.75%, 25.75% and 43.0%, respectively. conclusions it is suggested that c. fistula may protect rbc against sickling, in hypoxic conditions, in individuals with hbs gene defect. objectiv...
Red cell distribution width (RDW), an electronically determined index of anisocytosis, was examined in 60 patients with sickle cell anemia (Hb SS), 28 patients with hemoglobin sickle cell (SC) disease, and seven patients with sickle cell-beta(+) thalassemia (S-thal). All patients were adults and in the steady state of their disease. The RDW was greater in sickle cell patients than in 39 healthy...
Studies have questioned whether renal dysfunction in sickle cell disease is linked to hemolysis-associated vasculopathy. We have investigated renal function and markers of hemolysis in a cohort of 424 adult African-British patients with sickle cell disease. While significant associations were found in HbSS and HbSβ(0) (sickle cell anemia) patients with and without controlling for covariates bet...
This review addresses several areas of concern in the care of patients with sickle cell disease. In Sections I and II, the fundamental pathogenetic mechanisms of sickle cell disease and their clinical consequences are discussed. Dr. Narla presents the evidence for abnormal cell adhesiveness by SS cells and Dr. Rosse examines the role of the increased whole blood viscosity. In Section III, Dr. P...
