Biomarker Panel for PCOS-Associated Liver Steatosis in Adolescent Girls (COMPASS-pedPCOS)

Starting soon

Conditions studied: Polycystic Ovary Syndrome (PCOS), Metabolic Dysfunction-Associated Steatotic Liver Disease, Pediatric Obesity, Hyperandrogenism, Insulin Resistance Syndrome

In brief

This single-center, prospective, observational, cross-sectional mechanistic pilot study will evaluate whether polycystic ovary syndrome (PCOS) contributes to hepatic steatosis in adolescent girls independently of adiposity. A total of 150 girls aged 10-18 years will be enrolled into three groups of 50: girls with PCOS and obesity, age- and body mass index-matched girls with obesity but without PCOS, and healthy normal-weight girls. Each participant will undergo a single evaluation comprising anthropometry, clinical and biochemical phenotyping, transient elastography with controlled attenuation parameter and two-dimensional shear wave elastography, and a single venous blood sample. An extended biomarker panel will be measured by enzyme-linked immunosorbent assay (Fetuin-A, fibroblast growth factor 21, adiponectin, visfatin, cytokeratin-18 M30 and M65, soluble CD163, growth differentiation factor 15, 11-ketotestosterone, and 11beta-hydroxyandrostenedione), together with liquid chromatography-tandem mass spectrometry measurement of testosterone and sex hormone-binding globulin, and genotyping of PNPLA3 rs738409 and HSD17B13 rs72613567. The primary objective is to compare hepatic steatosis and the hepatokine/adipokine profile between the PCOS with obesity group and the adiposity-matched obesity control group, adjusting for body mass index z-score, insulin resistance, and free androgen index. No therapeutic intervention is assigned by the study protocol.

Who can join

Age: 10 and older, up to 18. Sex: female. Healthy volunteers: accepted.

You may qualify if…

Female, aged 10 to 18 years, with written informed consent from a parent or legal guardian and written assent from the child.
Group 1 (PCOS with obesity): both hyperandrogenism and oligo-anovulation required, based on adolescent-adapted Rotterdam criteria; body mass index at or above the 95th percentile.
Group 2 (Obesity control): body mass index at or above the 95th percentile, without features of PCOS, matched to Group 1 for age and body mass index.
Group 3 (Healthy control): healthy normal-weight girls (body mass index between the 5th and 84th percentile) without chronic disease, hyperandrogenism, or menstrual irregularity.

You may not qualify if…

Known acute or chronic liver disease (including viral, autoimmune, or Wilson disease) or use of hepatotoxic medication.
Endocrine disorders or secondary hyperandrogenism, including Cushing syndrome, hypothyroidism, uncontrolled diabetes mellitus, congenital adrenal hyperplasia, androgen-secreting tumour, or hyperprolactinaemia.
Syndromic or monogenic obesity (including Prader-Willi syndrome, Bardet-Biedl syndrome, Alström syndrome, MC4R or LEP variants) or a known genetic disorder.
