NCT03042923

Brief Summary

The objective of this project will be to determine whether patients with a surgical diagnosis of endometriosis have impaired intestinal permeability as compared with healthy controls. This would suggest the presence of an environmentally triggered and intestinally mediated association in the etiology of endometriosis. This would be a proof of concept trial to establish whether there is in fact a relationship worthy of future research.

Outcome Measures

Primary Outcomes (1)

  • lactulose:mannitol (L:M) oral challenge

    Urine is collected over six hours and is then measured for ratio of L:M. An L:M ratio \>0.10 is consistent with increased intestinal permeability. Normally the gut does not absorb lactulose unless permeability is present.

    6 hrs

Secondary Outcomes (1)

  • Surgical Findings

    24 hrs

Study Arms (2)

Treatment

Twenty patients, known to us through care at Women's Surgery Center and the private practice of Dr. R. Scott Furr, will be invited to enroll based on a history of pelvic pain and a plan for surgical evaluation and intervention

Drug: lactulose:mannitol (L:M) oral challenge

Control

Ten healthy female patients, without pelvic pain or history of autoimmune disease, will be asked to participate as controls.

Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Participants will be recruited through care at Women's Surgery Center and the private practice of Dr. R. Scott Furr and through Erlanger Women's Specialty Services and the practice of Dr. Shanti Mohling. Participants will be invited to enroll based on a history of pelvic pain and a plan for surgical evaluation and intervention. Ten healthy female women, without pelvic pain or history of autoimmune disease, will be asked to participate as controls.

You may qualify if:

  • Female patients with documented history of pelvic pain for the study arm.
  • Healthy female controls without history consistent with autoimmune disease or pelvic pain

You may not qualify if:

  • Co-morbid autoimmune disease such as Celiac disease, lupus, ankylosing spondylitis, alcoholism and diabetes which have been shown to exhibit elevated levels of Zonulin and therefore impaired intestinal permeability. Drinking alcohol and taking NSAIDS elevate intestinal permeability and would affect data.
