To estimate the expression of plasma soluble E-cadherin and the gene polymorphism in patients with pelvic inflammatory disease (PID).


Hospital-based case-control study.


University hospital.


Sixty-four women with PID.


Blood specimen collection of patients before and after they received treatment.

Main Outcome Measure(s):

Enzyme-linked immunosorbent assay and polymerase chain reaction–restriction fragment length polymorphism were respectively used to measure the plasma soluble E-cadherin level and E-cadherin polymorphism.


The level of plasma E-cadherin was significantly elevated in PID patients as compared to that in normal controls; it decreased significantly after treatment when compared to levels noted in same patients after they received treatment. When the cutoff level of plasma E-cadherin level was set to be 20.22 ng/ml based on ROC, the sensitivity, specificity, and the area under the curve of plasma E-cadherin level for predicting PID were 0.81, 0.80, and 0.835 (95% confidence interval (CI), 0.76-0.90). The adjusted odds ratio (AOR) for age, WBC, and CRP levels is 19.66 (5.48-70.47).


Elevated plasma soluble E-cadherin expression was involved in the pathogenesis of PID and useful for the diagnosis of PID.
