“…8 Several authors have studied how H63D mutations affect iron load in β-thalassemia carriers. In their study, Wilson et al 9 found that Egyptian β-thalassemia patients and carriers, who had homozygous H63D mutation, had significantly higher serum ferritin levels than those who did not. In another study, Melis et al 10 found that β-thalassemia carriers, who were homozygous for H63D mutations, had higher ferritin levels than those who were heterozygous for this HFE allele, or those who did not have it.…”

“…Sugere-se que o traço β-talassêmico se associe com razão hepcidina/ferritina reduzida (SULOVSKA et al, 2016;JONES et al, 2015;GUIMARÃES et al, 2015) e valores de absorção de ferro maiores que os esperados para a magnitude das suas reservas corporais (ZIMMERMAN et al, 2008). Além disso, observações clínicas de uma grande heterogeneidade do status de ferro, mesmo entre carreadores de uma mesma mutação HBB, motivou a investigação de possíveis efeitos sinérgicos entre a β-talassemia menor e genótipos associados com a hemocromatose hereditária (WILSON et al, 2015;ESTEVÃO et al, 2011;MADANI et al, 2011;YAMSRI et al, 2007;GARWAL et al, 2005;MARTINS et al, 2004;MELIS et al, 2002).…”

“…Na literatura, ainda é controversa a associação da heterozigose do alelo HFE 63D com a sobrecarga de ferro de indivíduos β-talassêmicos. Nesse modo de coherança, o alelo foi associado com variações nos biomarcadores do mineral em pacientes de Portugal (MARTINS et al, 2004) e do Egito (WILSON et al, 2015;MADANI et al, 2015), mas não da Itália (MELIS et al, 2002), Índia (GARWAL et al, 2005) ou Tailândia (YAMSRI et al, 2007). Entre casos brasileiros, Estevão e colaboradores (2011) não identificaram sua associação com valores de ferritina ou 132 saturação da transferrina, mesmo em análises estratificadas pelo gênero, faixa etária ou tipo de mutação HBB carreada pelos indivíduos (ESTEVÃO et al, 2011).…”
