Fisiopatologia das doenças falciformes: da mutação genética à insuficiência de múltiplos órgãos

Abstract: endothelial cells, leukocytes and platelets, and their role in the pathophysiology of vaso-occlusion. The clinical manifestations, like anemia, pain crises and multiorgan dysfunction are covered. Factors that modulate disease severity, like the co-inheritance of αthalassemia, gene mutations related to thrombophilia and the elevation of fetal hemoglobin are discussed. Rev. bras. hematol.

“…With this change, the hemoglobin molecule spatial structure is modified, forming aggregates of filaments that polymerize and precipitate, leaving the cell with sickle appearance. This phenomenon is largely responsible for the clinical features presented of patients with SCA (24) .…”

“…Anemia falciforme (AF) foi a primeira doença de base molecular que demonstrou que a hemoglobina destes pacientes tinha excesso de carga positiva em comparação com hemoglobinas de adultos saudáveis (Galkin et al, 2007;Zago & Pinto, 2007).…”

“…Consideramos que os fatores socioeconômicos também contribuem significativamente para a variabilidade clínica e de prognóstico de pessoas com doença falciforme. As condições de moradia, a qualidade e quantidade insuficiente da alimentação ingerida e a carência de assistência à saúde, muitas vezes, estão associadas à discriminação racial, baixa renda e baixa escolaridade (Zago;Pinto, 2007).…”
