PCOS Patients' Immune Alterations

July 10, 2025 updated by: Zhang Manna, Shanghai 10th People's Hospital

Evaluation of Immune Status in Patients With Polycystic Ovary Syndrome

In this study, the investigators will include PCOS patients and healthy women who meet the trial criteria from the clinical research centers of 3 hospitals, introduce the content of this study to participants, and invite participants to participate. Flow cytometry was used to detect the immune function of peripheral blood samples of PCOS patients, to clarify the immune function characteristics of PCOS patients, and to try to establish an evaluation method of the immune function of PCOS patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

PCOS patients and healthy women were recruited in outpatient clinics of three hospitals, and peripheral blood was retained for flow cytometry after completing relevant examinations. In this study, flow cytometry was used to detect the antigenic antibody reaction between the surface differentiation antigen of lymphocyte membrane and fluorescence-labeled antibody in human peripheral blood, and the unlabeled cells were dissolved. The number and percentage of cell groups expressing different markers were counted by the fluorescence detection system on flow cytometry.

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.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

  • Take letrozole, clomiphene, oral contraceptives, glucocorticoids, gonadotropins, gonadotropin-releasing hormone agonists, antiandrogens (spironolactone, cyproterone acetate, flutamide, etc.), and other medications for PCOS treatment within the last 3 months.
