Abstract
Problem
Immune system dysregulation is a major cause of unexplained recurrent miscarriage (URM). Women with URM need screening for their pregnancy microenvironment and immune regulators, to prevent spontaneous abortion.
Method of study
In this study, we evaluated NKT-like cell subsets in the peripheral venous blood of women with URM using flow cytometry. The expression levels of specifically related Th1 cytokines (IFN-γ and IL-2), Th2 cytokine (IL-4), and Th17 cytokines (IL-17), were measured using enzyme-linked immunosorbent assay.
Results
The percentage of CD16+CD56+NKT-like (Double Positive NKT-like; DPNKT-like) cell subset and the levels of IL-2 and IFN-γ were significantly elevated in the blood of non-pregnant and pregnant patients with URM compared with the healthy control groups, and these parameters were significantly increased after pregnancy in the same patients with URM. Based on the prevalence of the candidate immunological factors in patients with URM, the prognostic significance of the NKT-like cell subsets, IFN-γ, and IL-2 profiles were evaluated as potential predictors of URM. A cut-off point of 2.55% for the DPNKT-like cell subset in the blood and cut-off values of 39.5 and 20.5 pg/ml for the levels of IFN-γ and IL-2, respectively could be used for the prediction of the risk of spontaneous abortion. To the best of our knowledge, this is the first study that described the prognostic significance of the aforementioned immunological parameters before and after pregnancy, and highlighted the correlation of NKT-like cells and the candidate Th1 cytokines with pregnancy loss in women with URM.
Conclusions
DPNKT-like cells, IFN-γ, and IL-2 patient profiles could be used as markers to predict the risk of miscarriage in patients with URM.
