Plain English summary of protocol

Background and study aims
Asherman's syndrome is a condition that occurs when scar tissue forms inside the uterus and/or the cervix (the opening to the uterus) following surgery to the uterus. This scar tissue (adhesions) can cause the walls of the uterus to stick together and can reduce the size of the uterus. Asherman's syndrome can affect patterns of menstruation and fertility.

The aim of this study is to compare the cells of the lining of the uterus between patients with Asherman's syndrome and patients who have undergone surgery to the uterus and have not developed Asherman's syndrome.

Who can participate?
Patients with Asherman's syndrome and an equal number of patients a history of intrauterine surgery but without the formation of intrauterine adhesions.

What does the study involve?
Participants will undergo a standard hysteroscopy examination (an investigation using a camera on a thin tube that is inserted into the vagina to examine the cervix and inside of the uterus) during which an endometrial biopsy will be collected for analysis. Participants will be contacted for information about their reproductive outcomes for the following two years.

What are the possible benefits and risks of participating?
There are no special benefits or risks for patients in the study.

Where is the study run from?
The Department of Obstetrics and Gynecology of General Faculty Hospital (Czech Republic) and 1st Medical Faculty of Charles University in Prague (Czech Republic)

When is the study starting and how long is it expected to run for?
From January 2021 to December 2023

Who is funding the study?
Ministry of Health (Czech Republic)

Study objectivesPatients undergoing surgical intrauterine procedures differ according to their inflammatory reactivity, cellular response, and clinical or anamnestic parameters in the incidence of intrauterine adhesion formation.
Ethics approval(s)Approved 22/08/2019, Ethics Committee of General Faculty Hospital in Prague (Na Bojišti 1, Prague 2, 12808, Czech Republic; +420 224964131; eticka.komise@vfn.cz), ref: 1443/19 S-IV Grant
Health condition(s) or problem(s) studiedAsherman's syndrome
InterventionAfter enrolment, a detailed medical history will be taken and during the indicated hysteroscopy, an endometrial biopsy will be collected for single-cell analysis. Standard medical care follows. Every 6 months patients will receive a questionnaire about reproduction for another 3 years. There is no special observation (only one endometrial biopsy), and then there is 3 years follow-up.
Intervention typeOther
Primary outcome measure(s)

Characteristics of endometrial reactivity to insult measured using single-cell analysis during the indicated hysteroscopy at baseline

Key secondary outcome measure(s)

Reproductive outcomes of patients with Asherman's syndrome measured using questionnaires at baseline, 6, 12, 18, 24, 30, and 36 months

Completion date30/06/2025
