Abstract

Objective To test whether hemoglobin may accumulate in the peritoneal cavity in case of endometriosis and to assess whether heme oxygenases (HO), detoxifying heme, are expressed in ectopic endometrium and peritoneal cells.Design Prospective study involving patients with and without endometriosis.Setting Department of gynecology in a university hospital.Patient(s) Seventy-six patients undergoing laparoscopy for tubal sterilization or infertility and/or pelvic pain.Intervention(s) Collection of peritoneal fluid (PF), blood samples, and biopsies from endometrium and peritoneum.Main outcome measure(s) Measurement of free hemoglobin and its byproduct, total and direct bilirubin, in serum and PF and analysis of HO-1 and HO-2 expression in biopsies by reverse transcription polymerase chain reaction and semiquantitative immunohistochemistry.Result(s) Higher levels of hemoglobin were found in the PF of patients with endometriosis. There was no concomitant increase in bilirubin concentrations in the PF, and HO-1 was poorly expressed in peritoneal mesothelium and macrophages. Heme oxygenase-1 and HO-2 were strongly expressed in ectopic endometrium, especially in red lesions.Conclusion(s) Our results suggest that heme may be involved in the pathogenesis and/or development of endometriosis and that the HO system, although expressed, might be insufficient to detoxify heme in women with endometriosis.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Retrograde menstruation and bleeding of endometriotic lesions are responsible for erythrocytes in the pelvic cavity, which release pro-oxidant and proinflammatory factors like hemoglobin and its byproducts heme and iron.

    “Retrograde menstruation and bleeding of endometriotic lesions are responsible for the presence of erythrocytes in the pelvic cavity, which are likely to release pro-oxidant and proinflammatory factors like hemoglobin and its highly toxic byproducts heme and iron [27,28,29,30].”

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.
