Functional Proteins in Polycystic Ovary Syndrome

March 17, 2026 updated by: Iwona Magdalena Gawron, Jagiellonian University

Assessment of the Concentrations of Functional Proteins as Potential Early Markers of Insulin Resistance in Women With Polycystic Ovary Syndrome

The concentration of functional proteins: kisspeptin, ghrelin, zonulin will be measured and compared in women with polycystic ovary syndrome (PCOS) and insulin resistance (IR), in women with PCOS without IR, and in women without PCOS.

Detailed Description

Polycystic Ovary Syndrome (PCOS) is currently the most common endocrine disorder in women of reproductive age with an unknown etiology. A predominant metabolic feature of PCOS is insulin resistance (IR), which contributes to the pathogenesis and expression of other symptoms of the syndrome, such as hyperandrogenism. The metabolic disturbances in women with PCOS result in a higher incidence of cardiovascular diseases and endometrial cancer in the premenopausal age. The gold standard for assessing peripheral tissue sensitivity to insulin is the hyperinsulinemic-euglycemic clamp technique; however, this method is not commonly used in clinical practice due to its complexities. Instead, simpler tests, such as the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and fasting insulin measurements along with glucose tolerance tests, are employed. These methods are utilized for diagnosing insulin resistance rather than identifying predispositions. Therefore, there is an urgent need to identify more precise markers of IR that could be used in routine early-stage assessments. Given the long-term complications associated with PCOS, which can shorten life expectancy, early diagnosis and treatment of IR are crucial. Furthermore, such studies may contribute to exploring the etiopathogenesis of the syndrome. The discovery of "markers" that can predict or diagnose metabolic abnormalities at an early stage, prior to the onset of clinical symptoms, would facilitate early intervention and treatment, thus preventing a decline in quality of life associated with PCOS.

This study will measure and compare the concentrations of locally acting hormones: ghrelin, kisspeptin, and zonulin in three research groups: women with polycystic ovary syndrome (PCOS) and insulin resistance (IR), women with PCOS without IR, and women without PCOS. Measurements will be performed using immunoenzymatic methods (ELISA) and the Erba XL biochemical analyzer. Statistical calculations will be conducted using SPSS Statistics software.

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.
