Brief Summary

Chronic endometritis (CE) is characterized by the presence of atypical plasma cell infiltrates (CD138 positive) in the endometrial stroma. Recent analyzes suggest that CE adversely affects fertility by reducing endometrial receptivity, impairing decidualization and uterine contractility, thus increasing the risk of recurrent pregnancy loss and implantation failure. It is likely that a significant proportion of idiopathic infertility cases are due to CE. The diagnosis of CE is a challenge because the clinical examination and transvaginal ultrasonography are considered non-specific. The recent scientific research has been aimed at identifying hysteroscopic CE diagnostic criteria and establishing the compatibility of ultrasonographic, hysteroscopic, histopathological (including the use of immunohistochemical testing with antibodies against human CD138) and microbiological diagnoses. Preliminary literature results suggested that successful treatment of CE with antibiotics could improve live birth rates.

Outcome Measures

Primary Outcomes (1)

  • Determination of the cut-off point of the number of plasma cells/1 HPF corresponding to histological CE

    Diagnostic compatibility assessment of immunohistochemistry and histopathology will be performed to estimate the cut-off point for the number of plasma cells defining CE using the ROC (Receiver Operating Characteristic) curve

    3 months

Secondary Outcomes (10)

  • Assessment of the reliability of polyp visualization in diagnosing CE

    3 months

  • Assessment of the reliability of the visualization of focal endometrial hyperemia in the diagnosis of CE

    3 months

  • Assesment of the reliability of the visualization of diffuse endometrial hyperemia in the diagnosis of CE

    3 months

  • Assessment of the reliability of the visualization of endometrial micropolyps in the diagnosis of CE

    3 months

  • Assessment of the reliability of the visualization of endometrial edema in the diagnosis of CE

    3 months

  • +5 more secondary outcomes

Other Outcomes (1)

  • Evaluation of the frequency of isolation of a specific pathogen in the course of CE

    3 months
