The chronic inflammatory state in sickle cell anemia (SCA) is associated with several factors such as the following: endothelial damage; increased production of reactive oxygen species; hemolysis; increased expression of adhesion molecules by leukocytes, erythrocytes, and platelets; and increased production of proinflammatory cytokines. Genetic(More)
BACKGROUND Sickle cell disease is a hemoglobinopathy characterized by hemolytic anemia, increased susceptibility to infections and recurrent vaso-occlusive crises that reduces the quality of life of sufferers. OBJECTIVE To evaluate the correlation of the levels of lactate dehydrogenase, malonaldehyde and nitrite to fetal hemoglobin in patients with sickle(More)
BACKGROUND Sickle cell anemia is a hemoglobinopathy caused by a mutation that results in the production of an abnormal hemoglobin molecule, hemoglobin S (Hb S). This is responsible for profound physiological changes, such as the sickling of red blood cells. Several studies have shown that hydroxyurea protects against vaso-occlusive crises. OBJECTIVE The(More)
Hydroxyurea (HU) is the only drug approved for the induction of fetal hemoglobin. Besides this benefit, there are others such as the reduction of leukocyte and generation of nitric oxide (NO). Sickle cell anemia (SCA) is characterized by chronic hemolytic anemia and vaso-occlusive phenomena. The aim of this study was to evaluate the correlation of(More)
OBJECTIVE To determine the serum levels of malondialdehyde and nitrite in patients with sickle cell anemia treated or not with hydroxyurea in outpatient's setting. METHODS Of the 65 patients with sickle cell anemia selected for the study, 51 were not treated with hydroxyurea (Group 1), 14 made chronic use of hydroxyurea (Group 2) and 20 individuals had no(More)
OBJECTIVE To investigate the association between kidney dysfunction and haplotypes in sickle cell disease. METHODS A cohort of 84 sickle cell disease patients, treated in a public health service in Fortaleza, Brazil, was studied. Hemoglobin S haplotypes were obtained from 57 patients as they had recently received blood transfusions with 18 of them(More)
INTRODUCTION The Brazilian HIV/AIDS management and treatment guideline (PCDT), published in 2013, recommends and standardizes the use of highly active antiretroviral therapy (HAART) in all adult patients, in spite of LTCD4 count. This study aimed to analyze the first year of HAART use in patients from a reference center on HIV/AIDS management in Fortaleza,(More)
The aim of the study was to investigate the possible anti-inflammatory and antioxidant effects of BAY 73-6691 on neutrophils from SCA patients. This study included 35 patients with a molecular diagnosis of SCA, whose neutrophils were isolated and treated with BAY 73-6691 at the concentrations 100, 10, 1.0 and 0.1 μg/mL. LDH release and MTT assays were(More)
