NCT06890754

Brief Summary

This study investigates the role of hysteroscopy in diagnosing chronic endometritis (CE), a condition linked to female infertility but difficult to diagnose due to nonspecific symptoms. While histological examination with CD138 ( Cluster of Differentiation 138 )immunohistochemistry is the gold standard, hysteroscopy remains widely used. This prospective, multicenter study included infertile women with no uterine abnormalities on ultrasound. Hysteroscopy was performed using standardized criteria, and its diagnostic performance was compared to histopathology. Intra- and inter-observer variability were also assessed through blinded video evaluations by two specialists. The study aimed to determine the reliability of hysteroscopy in diagnosing CE and its agreement among different observers.

Outcome Measures

Primary Outcomes (2)

  • Proportion of Participants Undergoing Diagnostic Hysteroscopy

    Examination of the uterine cavity and the cervico-isthmic canal.

    peroperatively

  • Expression of CD138 Marker in Endometrial Biopsy

    An immunohistochemical study of plasma cell marker CD138 expression was systematically performed on all analyzed samples. The anti-CD138 monoclonal antibody (Clone Ml15, Leica Biosystems, Reference: PA0088), ready to use on the BOND immunohistochemistry automated system, was used.

    First 24 hours

Interventions

Diagnostic hysteroscopy. An IHC study of the expression of the plasma cell marker CD138 was systematically performed for all samples studied

Sampling MethodProbability Sample
Study Population

The study population consisted of infertile women aged 18 to 42 years with no uterine abnormalities on pelvic ultrasound. Exclusion criteria included biological inflammatory syndrome, recent acute genital infections (within three months), antibiotic therapy, autolysed biopsies, unusable hysteroscopy videos, atypical hyperplasia, and endometrial cancer. The sample size was determined based on the reported prevalence of chronic endometritis (CE) in infertile women, ranging from 2.8% to 30%, with a calculated target of 68 participants to ensure statistical significance at a 95% confidence level.

You may qualify if:

  • included women aged 18 to 42 years, consulting for infertility, with a pelvic ultrasound showing no uterine abnormalities

You may not qualify if:

  • Excluded from the study were patients with biological inflammatory syndrome, those on antibiotic therapy or with a recent acute genital infection (less than three months), autolysed biopsies, unusable hysteroscopy videos, atypical hyperplasia, or endometrial cancer.

Data Sharing

IPD Sharing
Will not share

This study's individual participant data (IPD) will be made available to researchers upon reasonable request. The shared data will include de-identified participant-level datasets containing: Demographic characteristics (age, Body Mass Index, smoking status, infertility duration, primary versus secondary infertility) Hysteroscopic findings (micro polyps, focal hyperaemia, diffuse hyperaemia, stromal oedema, strawberry aspect, haemorrhagic spots) Histopathological results (CD138, immunohistochemistry findings, plasma cell count per high-power field) Observer assessments (initial and repeat evaluations for intra- and inter-observer variability) All data will be de-identified to ensure confidentiality. Access will be granted to qualified researchers for meta-analyses, systematic reviews, or investigations related to chronic endometritis and infertility, following approval of a research proposal and data-sharing agreement.
