Study on Vaginal Microecology and Cervical Local Immune Function in Patients With Uterine Fibroids of Childbearing Age

September 23, 2023 updated by: Lin Yuan
The study participants are patients with uterine fibroids and healthy physical examination subjects from the First Affiliated Hospital of Shandong First Medical University (Shandong Qianfoshan Hospital). The main purpose of this study is to analyze the correlation between uterine fibroids and vaginal microecology and cervical local immune function in patients of childbearing age.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

(1) In this study, 150 women of childbearing age who are diagnosed with uterine fibroids in the First Affiliated Hospital of Shandong First Medical University (Shandong Qianfoshan Hospital) are selected as the study group; The differences of vaginal microenvironment and cervical local immune function are compared between 150 healthy women of childbearing age in the same period. (2) After the patients are enrolled, the general information (age, height, weight), menstrual status (age of menarche, menstrual period, cycle, bleeding pattern), clinical manifestations (abnormal uterine bleeding, infertility, abdominal pain), and previous medical history (hypertension, thyroid disease, etc.) of 150 patients with uterine fibroids will be collected. After the end of the first part of the experiment, 150 patients with uterine fibroids will be grouped according to vaginal microecological diagnosis, and the clinical characteristics of patients with uterine fibroids will be analyzed and compared.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

study group
Age 20-49 years old; Premenopausal; Clinical diagnosis of uterine myoma; Cervical liquid-based cytology and human papillomavirus typing test are negative.
Diagnostic test: Microscopic examination of vaginal discharge
Using gram-stained smears to detect vaginal secretions, and then the concentration and diversity of bacterial flora are observed using a microscope.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Bacterial vaginitis (BV) of vaginal microecosystem-150 people in each group
Time Frame: through study completion, an average of 2.5 year
Nugent score is currently an internationally accepted diagnostic method for BV. Lactobacillus, Gardnerella vaginalis, bacterioid bacteria and campylobacter with variable staining are evaluated by Gram staining and semi-quantitative evaluation method. The total score is the sum of the scores of the above 4 bacteria. 0 to 3 points: normal; 4 ~ 6 points: intermediate BV; ≥7 points: BV
through study completion, an average of 2.5 year
