Chronic Endometritis and IVF
NCT02646930 · View on ClinicalTrials.gov ↗
Study Summary
Background: Embryo quality is known to be a very important determinant to predict the implantation and pregnancy rate in IVF patients, however, the role of uterine integrity or endometrial receptivity cannot be overlooked. Chronic endometritis (CE) is an inflammation of the endometrium diagnosed by the presence of plasma cells in the endometrial stroma. There is not only no census on the definition of CE, the current literature on the impact of CE on reproductive outcome is controversial and consists only of retrospective studies with small sample sizes. Although there is a presumption that CE is related to poor IVF outcome, this belief has not been proven. Design: Prospective cohort study Setting: Infertility clinics of 2 academic medical centers Patients: Patients between the ages of ≥ 21 and ≤ 35 years old undergoing their first IVF cycle will be invited to participate. Main Outcome Measures: The primary outcome will be ongoing pregnancy after 12 weeks estimated gestational age (EGA) with previously documented fetal cardiac motion. Secondary outcomes will include pregnancy loss rate as defined by chemical pregnancy, blighted ovum or loss of fetal cardiac motion before 12 weeks EGA. Materials and Methods: The cycle prior to IVF, patients will undergo an in-office endometrial biopsy on cycle days 19-24. Samples will be stained for CD138 and the number of plasma cells will be quantified. The number of plasma cells in a sample that yields the best sensitivity and specificity for pregnancy will be determined by a Receiver-Operator-Curve. This number will then be used as a dichotomous variable to assign categories of "positive for CE" and "negative for CE." Pregnancy and miscarriage rates will then be determined in the positive and negative CE sample with Chi Square Analysis. A secondary sub analysis will be performed to determine pregnancy and miscarriage rates in patients who declined to participate in the study. Expected Results: The investigators hypothesize

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02646930
The ClinicalTrials.gov registry entry for NCT02646930 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 57 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Duke University, which has 1,129 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with in Vitro Fertilization appearing as the primary indexed condition, and to 1 intervention — of which Endometrial biopsy is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02646930 reports 2 study locations spanning 2 distinct geographic areas — top geographies include Illinois, North Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
