Problem Immunotherapies [leukocyte immunization, intravenous immunoglobulin (IVIG)] introduced to treat women with recurrent spontaneous abortions (RSA) have still controversial results in most clinical trials. A selection of these patients would be advantageous for higher efficacy. Method of study A complex immunological panel assay was offered to patients with reproductive failure without any other known cause. We focused here on the cellular immunological parameters.
Results High cytotoxic T lymphocyte precursor frequency and cell-mediated cytotoxic activity and a rather high natural killer cell activity were found in alloimmune RSA patients. Thirty-two patients were investigated by immunological assays and in 78% of the women an alloimmune background could be defined. The efficacy of IVIG treatment was 96% in this group. Conclusions The novel cellular immunological assays proved to be favourable for the indication of RSA patients and showed the usefulness of this selection process for effective immunotherapy.
