Changes in serum inflammatory factors in group B streptococcal infection and their predictive value for premature rupture of membranes complicated by chorioamnionitis

Abstract

Objective: The aim of this study as to unveil changes in serum inflammatory factors in pregnant women with genital tract group B Streptococcus (GBS) infection and their predictive value for premature rupture of membranes (PROM) complicated by chorioamnionitis (CS) and adverse pregnancy outcomes. Methods: The value of serum inflammatory factor levels in predicting PROM complicating CS and adverse pregnancy outcomes in GBS-infected pregnant women was evaluated by ELISA. Results: Serum IL-6, TNF-α, PCT and hs-CRP levels were higher in pregnant women with GBS infection. The combined diagnosis of these factors had excellent diagnostic value in PROM complicating CS and adverse pregnancy outcomes. Conclusion: Joint prediction of IL-6, TNF-α, PCT and hs-CRP has the best predictive value for PROM complicating CS and adverse pregnancy outcomes.

Summary points

• Our study aimed to unveil changes in serum inflammatory factors in pregnant women with group B Streptococcus (GBS) infection and their predictive value for premature rupture of membranes (PROM) complicated by chorioamnionitis (CS) and adverse pregnancy outcomes.

• The incidence of PROM was higher in the GBS infection group than in the non-GBS infection group.

• High serum IL-6, TNF-α, procalcitonin (PCT) and high-sensitivity CRP (hs-CRP) levels were seen in pregnant women with GBS infection and adverse pregnancy outcomes, as well as GBS-infected pregnant women with PROM complicated by CS.

• Serum IL-6, TNF-α, PCT and hs-CRP levels have a certain diagnostic value for PROM complicated by CS and adverse pregnancy outcomes in GBS-infected pregnant women.

• The diagnostic value of the joint prediction of each indicator was greater than the individual prediction of each indicator.

• This paper may provide a quantitative reference for clinical prediction of the occurrence of PROM complicating CS in GBS-infected pregnant women.
