RESUMO
A sangria terapêutica é um procedimento hemoterápico de simples realização, eficaz quando indicada corretamente. Atualmente, as principais doenças que se beneficiam com este tratamento são as hiperferritinemias e as eritrocitoses. O presente estudo teve como objetivo principal conhecer o perfil dos pacientes submetidos à sangria terapêutica em um consultório privado de hematologia, localizado na região sul de Santa Catarina. Trata-se de estudo observacional e retrospectivo, com análise quantitativa de dados secundários. Todos os 113 pacientes identificados compuseram a amostra final. As indicações de sangria mais prevalentes foram hiperferritinemia secundária (46,9%) e hiperferritinemia com mutação do gene HFE (44,2%). A média de idade dos pacientes foi de 53,12 anos, sendo a maioria composta por homens (84,1%), todos da raça branca, e 31% procedentes de Criciúma. Destes pacientes, 77,9% realizaram estudo genético, o qual mostrou 56,8% positivos para hiperferritinemia com mutação do gene HFE, 6,8% para o gene da policitemia vera e 36,4% com resultado negativo. Ao comparar os índices laboratoriais antes e após a sangria terapêutica, observouse redução estatisticamente significativa nos valores de ferritina sérica e saturação de transferrina nos casos de hiperferritinemia com mutação do gene HFE e de ferritina sérica para hiperferritinemia secundária. Conclui-se que o perfil dos pacientes submetidos à sangria terapêutica na região sul de Santa Catarina, no período estudado, é composto principalmente por homens, acima de 50 anos de idade, e que a indicação mais prevalente para o tratamento são as sobrecargas de ferro.
ABSTRACT
Therapeutic bloodletting is a haemotherapic procedure of easy execution and effective when indicated correctly. Currently, the main diseases that benefit from this treatment are the iron overload syndromes and erythrocytosis. The main objective of this study was to know the profile of patients submitted to bloodletting therapy in a private hematology practice, located in the southern region of Santa Catarina. It is an observational and retrospective study with quantitative analysis of secondary data. All the 113 patients identified have composed the final sample. The most prevalent phlebotomy indications were secondary iron overload (46.9%) and iron overload with mutation of the HFE gene (44.2%). The average age of the patients was 53.12 years, most of which were men (84.1%), all of the white race and 31.0% of Criciúma. Of these patients, 77.9% performed genetic study, being 56.8% positive for iron overload with mutation of the HFE gene, 6.8% for the polycythemia vera gene and 36.4% showed negative result. By comparing the laboratory indices before and after the therapeutic bloodletting, significant reduction was observed in the values of serum ferritin and transferrin saturation in the iron overload with mutation of the HFE gene cases. About secondary iron overload, it was observed significant reduction only in serum ferritin. It's concluded that the profile of patients who are submitted to therapeutic bloodletting in the southern region of Santa Catarina, in the studied period, is composed mainly of men, above 50 years of age and the most prevalent indication for treatment are the iron overloads.
