Abstract
Abstract Objective To describe a patient with primary infertility and recurrent implantation failure (RIF) and coexistence of peripheral blood immunophenotypic dysregulation of lymphocytes and alloimmune and autoimmune abnormalities. The hypothesis is that functionally distinct immunological abnormalities might better explain the immunological etiology of RIF than individual abnormalities in some patients. Subjects and methods We present clinical and immunological data. Results A patient with primary infertility and RIF had peripheral blood immunophenotypic abnormalities of T, B and NK-cells, unusually high shared HLA antigens with her partner, and antiphospholipid antibodies. Conclusion Functionally distinct immunological abnormalities may coexist in some women with RIF after in vitro fertilization.
