Is inflammation the major driver of polycystic ovary syndrome (PCOS)? A proteomic approach to understanding PCOS in adolescents and the search for novel non-invasive biomarkers

Harriet Gunn/ , Hällqvist Jenny , Doykov Ivan , Steinbeck Katharine , Mills Kevin

Background and Methods: PCOS is common and associated with significant comorbidity. However, its pathogenesis is complex and poorly understood. We have developed new methods for deep phenotyping discovery proteomic profiling of urine, aiming to identify disease mechanisms, drug targets and novel non-invasive biomarkers for PCOS in adolescents. Here, we present the baseline proteomic data from our prospective, longitudinal study (n=40). We undertook proteomic analysis ...

Inflammation and polycystic ovary syndrome (PCOS). Utilising proteomic analysis to unravel the link between inflammatory proteins and PCOS in adolescents

Gunn Harriet , Oberg Emma , Hällqvist Jenny , Lindén Hirschberg Angelica , Steinbeck Katharine , Mills Kevin

Background and Methods: PCOS is common in adolescents and imparts a significant health and economic burden. Yet, our understanding of its complex pathogenesis is lacking. Proteomic analyses would be a valuable tool to deepen our knowledge of the biological pathways which underpin PCOS, and to identify novel biomarkers to diagnose and monitor this common condition. Therefore, we undertook a deep phenotyping discovery proteomic profiling (nano-2D-LC-QTOF MSe) on...

Polycystic Ovarian Syndrome in Adolescents: Utilising Discovery Proteomics and the Search for to Identify Novel Non-Invasive Biomarkers

Gunn Harriet , Forysth Vhari , Hällqvist Jenny , Viner Russell , Mills Kevin , Steinbeck Katharine

Background: Polycystic ovarian syndrome (PCOS) is common, affecting up to one-fifth of females. PCOS is associated with significant comorbidity including metabolic dysfunction, pro-inflammation and mood disorders. Despite this, it is poorly understood, and diagnosis and management remain challenging in adolescents. Proteomics enables the better understanding of disease mechanisms and facilitates the identification of novel biomarkers.<st...

Polycystic Ovarian Syndrome in Adolescents: Characterising the Clinical Phenotype and the Role of Precision Medicine

Gunn Harriet , Agarwalla Vathsala , Skinner Rachel , Milne Bronwyn , Mills Kevin , Steinbeck Katharine

Background: Polycystic ovarian syndrome (PCOS) is the most common hormone disorder in adolescent and young adult females, affecting 4–20% of the population. PCOS is associated with metabolic dysfunction, pro-inflammatory processes and mood disorders. Despite this, it is poorly understood in younger adolescents, and diagnosis and management remain challenging.Objectives: To better understand the clinical phenotype of PCOS in adolescents. Subsequently...

Can we Standardize Sex Assignment in 45,X/46,XY Mixed Gonadal Dysgenesis?

Colindres Johanna Viau , Eugster Erica , Smith O'Brian , Gunn Sheila , Mendiratta Meenal , Karaviti Lefkothea

Background: Patients with 45,X/46,XY mixed gonadal dysgenesis (MGD) have variable phenotypes leading to both male and female sex assignments. A multidisciplinary team should guide the process of sex assignment, however a standardized approach may provide objective guidance for the team as well as a tool for settings without such resources. One of the most important considerations for sex assignment is the hormonal production, which often determines the degree of virilization. ...

Salt Sensitivity of Blood Pressure at Age 7–8 Years in Preterm Born Children

Ruys Charlotte A , Lafeber Harrie N , Rotteveel Joost , Finken Martijn J J

Background: Preterm birth is associated with hypertension and increased fat contents in later life. Salt sensitivity (SS) could be a mechanism underlying this relationship. In adults SS has been recognised as a cause of hypertension that is related to low birth weight and obesity.Objective and hypotheses: We studied the prevalence of SS in 7–8-year old children born <32 weeks of gestation and/or with a birth weight <1500 g as well as its rel...

Sex-Specific Differences in Hypothalamus-Pituitary-Adrenal Axis Activity in Newborns with Very Low Birth Weight

van der Voorn Bibian , de Waard Marita , Rotteveel Joost , Hartmann Michaela , van Goudoever Johannes , Lafeber Harrie , Wudy Stefan , Finken Martijn

Background: Male preterm infants are at increased risk of neonatal mortality when compared to their female counterparts. The mechanisms explaining this male disadvantage are not fully elucidated yet.Objective and hypotheses: To compare glucocorticoid metabolite excretion in urine obtained at day 10 between male and female infants born with a very low birth weight (VLBW; i.e. <1500 g). We hypothesized that male preterm infants have impaired adrenocort...
