Anemia falciforme: una revisión sobre el genotipo de la enfermedad, haplotipos, diagnóstico y estudios asociados

Rev. méd. Chile; 149 (9), 2021
Sickle cell anemia is a type of hemoglobinopathy characterized by a specific mutation in the beta globin gene with the consequent generation of an unstable hemoglobin that crystallizes in a state of hypoxia. This causes a change in the structure of the red blood cell, which ends up producing vaso-occlusi...

Occurrence of unusual haemoglobinopathies in balochistan: hb sd and hb se - presentation with osteomyelitis

ABSTRACT Objective: To describe two cases of unusual variants of sickle cell disease. Case description: We present two cases of sickle cell disease variants (haemoglobinopathies), from unrelated families, in the state of Balochistan (Pakistan). One was diagnosed with sickle cell disease in the haemog...

Evaluation of hydroxyurea genotoxicity in patients with sickle cell disease

Einstein (Säo Paulo); 17 (4), 2019
ABSTRACT Objective To evaluate the induction of DNA damage in peripheral blood mononuclear cells of patients with sickle cell disease, SS and SC genotypes, treated with hydroxyurea. Methods The study subjects were divided into two groups: one group of 22 patients with sickle cell disease, SS and SC g...

Prevalência de hemoglobinas variantes em comunidades quilombolas no estado do Piauí, Brasil

Resumo As hemoglobinas variantes (Hb) decorrem de mutações nos genes da globina. As variantes estruturais mais frequentes são HbS, HbC, HbD e HbE. O gene da hemoglobina S tem frequência elevada na América, enquanto que no Brasil é maior no Sudeste e Nordeste. O presente artigo tem por objetivo inve...

Profile of Reproductive Issues Associated with Different Sickle Cell Disease Genotypes

Abstract Purpose To describe the reproductive variables associated with different sickle cell disease (SCD) genotypes and the influence of contraceptive methods on acute painful episodes among the women with the homozygous hemoglobin S (HbSS) genotype. Methods A cross-sectional study was conducted be...

Genetic determinants and stroke in children with sickle cell disease

J. pediatr. (Rio J.); 92 (6), 2016
Abstract Objective: To verify genetic determinants associated with stroke in children with sickle cell disease (SCD). Methods: Prospective cohort with 110 children submitted to neonatal screening by the Neonatal Screening Program, between 1998 and 2007, with SCD diagnosis, followed at a regional refere...

Síndrome drepanocítico: Asociación de hemoglobina S Y &β talasemia
Sickle cell syndrome. Association between hemoglobin S and β thalassemia

Medicina (B.Aires); 76 (6), 2016
El síndrome drepanocítico HbS/β talasemia responde a la herencia de tipo mendeliana en simultáneo de un alelo βs de la hemoglobina S (HbS) y un alelo de β talasemia. Vinculado fundamentalmente a individuos que comparten ascendencia africana y de países del Mediterráneo. La mutación r...

Genetic variants associated with fetal hemoglobin levels show the diverse ethnic origin in Colombian patients with sickle cell anemia

Biomédica (Bogotá); 35 (3), 2015
Introduction: Fetal hemoglobin is an important factor in modulating the severity of sickle cell anemia. Its level in peripheral blood underlies strong genetic determination. Associated loci with increased levels of fetal hemoglobin display population-specific allele frequencies. Objective: We investigate...

Manifestações retinianas em pacientes portadores de anemia de células falciformes

Rev. bras. oftalmol; 70 (5), 2011
A Organização Mundial de Saúde estima que mais de 5 por cento da população mundial seja portadora de algum tipo de hemoglobinopatia. Dentre essas encontramos a anemia de células falciformes, que tem seu principal efeito lesivo sobre a vasculatura periférica. Na retina, as lesões falciformes possu...

Colelitíase associada à anemia falciforme na infância
Cholelithiasis related to sickle cell disease in childhood

A colelitíase na infância é considerada uma situação rara. É mais comun em crianças do sexo feminino, entre 8 e 12 anos de idade. As causas mais comuns de coleitíase na crinça são as anemias hemolíticas, por causa das altas taxas de excreção da bilirrubina, devido à hemólise. No mundo, 40 ...
