ABSTRACT

Objective: To determine the prevalence of chronic endometritis in infertile patients by evaluating hysteroscopy and endometrial biopsy with endometrial histologic analysis and identification of plasma cells by CD138-positive immunohistochemistry.
Materials and Methods: Observational, retrospective study performed from March 2016 to November 2021 at the Center for Assisted Reproduction of Saltillo (CREAS), Coahuila, Mexico, in patients who consulted for infertility. Chronic endometritis was diagnosed by hysteroscopy and endometrial biopsy with CD138 immunohistochemistry. The prevalence and diagnostic accuracy of hysteroscopy and endometrial biopsy were analysed. The association between specific hysteroscopic features and chronic endometritis confirmed by CD138-positive endometrial biopsy was also investigated.
Results: The prevalence of chronic endometritis by CD138-positive endometrial biopsy in the 170 patients studied was 36% (n = 62) and by hysteroscopy 48.8% (n = 83), the latter with a sensitivity of 48.3%, specificity of 50.9%, positive and negative predictive values of 36.1 and 63.2%, respectively. In relation to hysteroscopic features, endometrial hyperemia had a statistically significant relationship with the prevalence of chronic endometritis (p-value = 0.008; RM = 0.357; 95%CI: 0.14- 0.81) and with ≥ 2 features suggestive of chronic endometritis (p-value = 0.015; RM = 3.63; 95%CI: 1.15-12.69).
Conclusions: In the diagnostic process of infertile patients, it is important to exclude chronic endometritis. It is crucial to use diagnostic tools such as hysteroscopy and to confirm the diagnosis by endometrial biopsy with positive CD138 immunohistochemistry in order to guide treatment.
