Background: Steroid profiling by LC-MS/MS is increasingly used in endocrine research, and is being introduced in the clinical practice. Due to the large disagreement with previous immunoassays, and to the enlarged panel of measurable steroids, novel and robust reference intervals (RIs) need to be established. Steroid circulating levels are known to be influenced by several physio-pathological factors, such as age, gender, stress and metabolic status. Therefore, generating unbi...

Endocrine clinical practice strongly relies on normative data for the assessment of hormonal imbalance. However, the generation of robust steroids reference intervals (RIs) remains a challenge. As the steroids circulating levels are influenced by many procedural aspects related to blood collection (time, fasting state) and physio-pathological factors, such as age, sex, stress and metabolic status, the need for partitioning RIs is mandatory. Furthermore, unbiased healthy, drug-...

The comprehension of the network of metabolic processes may help the understanding of the molecular pathways driving obesity and related complications. However this is a hard task due to the large number of actors and their complex interplay. We aimed at exploring by targeted metabolomic the circulating metabolite profile in lean (NW, n=42; BMI: 18.5–24.9 kg/m2) and age-matched overweight/obese (OB, n=37, BMI≥25.0 kg/m2), drug...
