ABSTRACT
Objective:To evaluate curative impact of booster immunization with paternal lymphocytes on recurrent spontaneous abortors(RSA)with less reaction of primary patermal lymphocyte immunization.Methods:RSA patients with insufficient materno-fetal immuno-recognition were selected by flow cytometry of blocking antibody analysis and immunized with either induced paternal lymphocytes pretreated by IFN-? in vitro to those of anti-CD3-BE and anti-CD4-BE Ab lower than 0% or direct intradermal vaccination with their paternal lymphocytes without IFN-? pretreatment to those of anti-CD3-BE Ab beyond 0%.Reassessment of blocking antibodies was performed at the end of the second immnunization course.Results:Levels of blocking antibodies were significantly raised after the secondary booster immunization in RSA with insufficient materno-fetal immnuno-recognition whose blocking antibodies continuously decreased after being treated by the primary paternal lymphocyte immunization.No improvement of parameters was observed except the blocking effect in patients receiving secondary direct intradermal vaccination treatment.Conclusion:It is necessary for the RSA with insufficient materno-fetal immuno-recognition to experience secondary booster immunization preferably with paternal lymphocytes pretreated by IFN-? in vitro.
