ABSTRACT

Preformed donor-specific human leukocyte antigen (HLA) antibodies have been associated with allograft dysfunction and failure. However, recipients of HLA-identical kidneys can develop acute humoral rejection, implicating putative pathogenic antibodies that are directed against non-HLA antigens. We investigated the presence of endothelial cell-reactive antibodies in 11 patients who experienced early loss of their transplanted kidneys owing to humoral rejection and 1 loss from renal venal thrombosis. We examined the potential efficacy of intravenous immunoglobulin to block the binding of these antibodies, as previously suggested for anti-HLA antibodies.

ABSTRACT

Uma análise do perfil dos antígenos HLA de classe II numa amostra da populaçäo de Säo Paulo é descrita neste trabalho. Os dados foram obtidos através de técnicas de amplificaçäo gênica utilizando-se iniciadores seqüências-específicos para HLA-DRB (PCR-SSP) ou amplificaçäo gênica seguida de hibridaçäo com oligonucleotídeos específicos (PCR-SSOP) para HLA-DQA e DQB. Foram calculadas as freqüências gênicas e as freqüências haplotípicas DRB-DQB e DQA-DQB e a populaçäo mostrou estar em equilíbrio genético de acordo com a lei de Hardy-Weinberg. Finalmente, comparamos também os dados obtidos com os da populaçäo de Porto Velho, Rondônia, salientando a importância da obtençäo de dados regionais para os controles quando se estuda este complexo sistema genético.
