Peripheral blood T- and B-cell immunophenotypic abnormalities in selected women with unexplained recurrent miscarriage

摘要

We aimed to investigate if women with recurrent miscarriage disclosed abnormalities in the maturation and activation status of peripheral blood lymphocyte subsets. In a case control study, 24 women with recurrent miscarriage, 37 women with children but no history of miscarriage and 39 women without previous pregnancies were evaluated. Lymphocyte subsets were evaluated using three-colour flow-cytometry. Selected women with recurrent miscarriage had significantly higher absolute counts of central memory CD4+ T-cells, CDS+ DR+ T-cells and memory non-switched B-cells than the control groups. Recurrent miscarriage may be associated with abnormalities of the maturation and activation status of peripheral blood T and B lymphocytes. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
