PG - 525-9 AB - We have endeavored to ascertain the possible existence of deviant recognition of antigens controlled by the major histocompatibility complex by lymphocytes originating in couples with a history of multiple spontaneous abortions of unknown cause. Human leukocyte antigen (HLA) typing, as well as one-way mixed lymphocyte culture (MLC) tests, were performed on 33 couples with multiple spontaneous abortions and subsequently compared to 30 fertile couples with no abortion history. No significant differences in the frequency of HLA were detected between the fertile and infertile groups. The frequencies of shared HLA-A and -B antigens among members of the couples were similar in both groups. In 70% of the cases studied, the husbands revealed a depressed cellular response to their respective wives; whereas reactivity to cells from other women proved normal. However, the response of allogeneic controls to these infertile women was normal. This implies that women with multiple abortions are not poor stimulators. The specific one-way decrease in the MLC reactivity appeared to be mediated by female-derived suppressor mechanisms and may be considered as one of the causes of the interrupted development of pregnancy in vivo.
