ABSTRACT

A proposta deste estudo foi identificar os alelos que codificam o HLA-DQ1 envolvidos na ausência de resposta imune celular em 60 pacientes hansenianos (50LL e 10BL) Mitsuda negativos. Os resultados obtidos mostraram a presença do alelo HLA-DQB1*0501 em 48.30% dos pacientes, seguido do HLA-DQB1*0602 em 31.66%, ambos subtipos do fenótipo HLA-DQB1*01. Apesar do predomínio destes alelos, não se pode afirmar que eles sejam os responsáveis pela ausência de resposta ao teste de Mitsuda. Sugerimos mais estudos neste segmento para a confirmação dos resultados.


The purpose of this study was to identify the gene encoding HLA-DQ1 involved in the absence of cellular immune response in 60 Mitsuda negative leprosy patients (50LL and 10BL). The results showed the presence of HLA-DQB1*0501 in 48.30% of patients, followed by HLA-DQB1*0602 in 31.66%, both subtypes of the phenotype HLA-DQB1*01. Despite the prevalence of these alleles, we can not say that they are responsible for the lack of response to the Mitsuda antigen. We suggest further studies to confirm the results.
