Trial summary
Chronic inflammation in polycystic ovary syndrome (PCOS) may be the result of dysregulation of cytokine production (due to insulin resistance, excess visceral fat and hyperandrogenemia), i.e., overproduction of pro-inflammatory factors (e.g. TNF, IL-1, IL-6) in relation to anti-inflammatory ones (IL-10).

About this study
Official title: The Influence of Subclinical Hypothyroidism on Chronic Inflammation Activity in Women With Different PCOS Phenotypes
Chronic inflammation in polycystic ovary syndrome (PCOS) may be the result of dysregulation of cytokine production (due to insulin resistance, excess visceral fat and hyperandrogenemia), i.e., overproduction of pro-inflammatory factors (e.g. TNF, IL-1, IL-6) in relation to anti-inflammatory ones (IL-10). This condition may be an important link between obesity and insulin resistance, which is crucial in the etiopathogenesis of the syndrome. However, it is not known whether it results from the tendency to accumulate adipose tissue or is a feature of the syndrome itself. Concomitant endocrinopathies, i.e. obesity, dyslipidemia, insulin resistance, diabetes and thyroid diseases, may additionally influence the activity of chronic inflammation. There is no data indicating the relationship between chronic inflammation and PCOS phenotypes, the severity of metabolic disorders, ovarian reserve and the influence of thyroid function on its activity in PCOS.
Read the detailed description
The aim of the study is:
- to assess and compare serum concentrations of selected inflammatory markers (leucocytosis, CRP, procalcitonin, fibrinogen, ferritin, IL-1, IL-6, IL-10, TNF-alpha) in women with different phenotypes PCOS and hypothalamic-pituitary-ovarian axis dysfunction (HPOD) (control), ii) to evaluate the impact of subclinical hypothyroidism (defined as TSH>2.5 uIU/ml, fT3 3,1-6,80 pmol/l, fT4 12,0-22,0 pmol/l), with the presence and absence of circulating antithyroid antibodies (a-TPO and a-TG), on the balance between anti- and pro-inflammatory factors in women with different PCOS and HPOD phenotypes, iii) to assess the impact of imbalance between anti- and pro-inflammatory factors in women with different PCOS and HPOD phenotypes on ovarian reserve indices, expressed as FSH and AMH concentrations.
The study population will be characterized in terms of demographic (age, BMI), gynecological (age of first and last menstrual period, cycle length, history of reproductive organ surgeries, ultrasound measurements of endometrial width, ovarian volume) and obstetrics (pregnancies, childbirth, miscarriages) data. PCOS syndrome (and its phenotypes) will be recognized by the Rotterdam criteria. HPOD will be diagnosed according to WHO criteria. During hospitalization, blood samples will be collected for scheduled analyzes (30 ml of blood in total).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Chronic inflammation in polycystic ovary syndrome (PCOS) may be the result of dysregulation of cytokine production (due to insulin resistance, excess visceral fat and hyperandrogenemia), i.e., overproduction of pro-inflammatory factors (e.g. TNF, IL-1, IL-6) in relation to anti-inflammatory ones (IL-10). This condition may be an important link between obesity and insulin resistance, which is crucial in the etiopathogenesis of the syndrome. However, it is not known whether it results from the tendency to accumulate adipose tissue or is a feature of the syndrome itself. Concomitant endocrinopathies, i.e. obesity, dyslipidemia, insulin resistance, diabetes and thyroid diseases, may additionally influence the activity of chronic inflammation. There is no data indicating the relationship between chronic inflammation and PCOS phenotypes, the severity of metabolic disorders, ovarian reserve and the influence of thyroid function on its activity in PCOS.

Questions about this trial
What is this clinical trial studying?
A study testing Measurement and comparison of leucocytosis and concentrations of CRP, procalcitonin, fibrinogen, ferritin, IL-1, IL-6, IL-10, TNF-alpha in both study arms, Evaluation of the impact of subclinical hypothyroidism, with present/ absent antithyroid antibodies, on the balance between anti- and pro-inflammatory factors in women in both study arms and Assessment of the impact of imbalance between anti- and pro-inflammatory factors in women with different PCOS and HPOD phenotypes on ovarian reserve indices in people with PCOS (Polycystic Ovary Syndrome) of Bilateral Ovaries and Subclinical hypothyroïdism, run by Jagiellonian University at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Values of inflammation parameters - leukocytosis in peripheral blood in both study arms (time frame: up to 6 months). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2025.
