ABSTRACT
Investigar a associação dos alelos HLA-A, -B e -DRB1 com a ocorrência de Aborto Espontâneo Recorrente. Estudo caso-controle com 200 mulheres com idade entre 18 e 35 anos, sendo a amostra de conveniência com 100 mulheres que tiveram aborto espontâneo recorrente idiopático e 100 mulheres sem aborto e com dois ou mais filhos. A obtenção do DNA Genômico foi de sangue periférico, sendo a extração realizada a partir de 500l do Buffy-Coat conservado a -20°C. A Tipificação HLA foi feita pelo método PCR-SSOP ( O alelo A*34 apresentou frequência significativamente maior no grupo caso em relação ao controle (4,0 Foi demonstrado que o alelo HLA-A*34 é fator de risco para o abortamento ...
To investigate the association of the HLA-A, -B and -DRB1 alleles with the occurrence of Recurrent Spontaneous Abortion. A case-control study of 200 women aged 18 to 35 years, consisting of a convenience sample of 100 women who had idiopathic recurrent spontaneous abortion and 100 women without abortion and with two or more children. Peripheral blood genomic DNA was extracted from 500l of Buffy Coat stored at -20°C. HLA typing was performed by the PCR-SSOP method (Polymerase Chain Reaction - Specific Sequence of Oligonucleotides Probes, One Lambda(r), CA, USA). The regions of the amplified DNA were exon 2 and 3 for the A and B The frequency of the A*34 allele was significantly higher in the case group compared to control (4.0 It was shown that the HLA-A*34 allele is a risk factor for recurrent spontaneous abortion, while the HLA-A*24 and HLA-B*35 alleles are associated with ...Subject(s)
