Abstract

Objective To identify a potential diagnostic endometriosis marker using matrix-enhanced laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS)-based urinary proteomics.Design Prospective randomized pilot study.Setting University hospital, tertiary referral center for endometriosis.Patient(s) 53 women undergoing laparoscopic surgery for pain and/or infertility comprising 30 women without endometriosis and 23 with endometriosis.Intervention(s) Laparoscopy and urine specimens.Main outcome measure(s) Urinary peptide profiles.Result(s) We observed distinct patterns of peptide profiles in the urine samples of women presenting with typical clinical symptoms of endometriosis. Six statistically significant putative peptide markers were identified (four during the periovulatory phase and two during the luteal phase) by comparing controls with moderate/severe endometriosis patients. The periovulatory peptide mass of 1,767.1 Da and the luteal peptide mass of 1,824.3 Da both showed a sensitivity of 75% and a specificity of 85% and 71%, respectively. Also detected were seven peptide markers (two during the periovulatory phase and five during the luteal phase) by comparing the urinary peptide profiles of patients with minimal/mild to moderate/severe endometriosis. The periovulatory peptide mass of 3,280.9 Da and the luteal peptide mass of 1,933.8 Da showed a sensitivity of 82% and 75% and a specificity of 88% and 75%, respectively.Conclusion(s) Urinary proteomic analysis may provide a novel method of diagnosing and staging endometriosis.

  • Several groups have reported differential peptide profiles in the urine of women with endometriosis relative to women without endometriosis at surgery using MALDI-TOF MS.

    “Using matrix assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS), several groups have reported differential peptide profiles in the urine of women with endometriosis relative to that of women without endometriosis at surgery [102, 106].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
