Long-term hair cortisone and perceived stress are associated with long-term hedonic eating tendencies in patients with obesity.

Introduction: Long-term biological stress, reflected in hair cortisol and cortisone levels, predicts future weight gain and metabolic deterioration. This is likely at least partially mediated by glucocorticoid-induced increases in hedonic overeating. Yet, the relationship between long-term biological stress and long-term hedonic eating tendencies remains to be elucidated.

Reversal of insulin resistance in people with obesity by lifestyle-induced weight loss does not impact the proportion of circulating 12α-hydroxylated bile acids.

Aim: Bile acids (BAs) are implicated in the pathogenesis of several metabolic syndrome-related diseases, including insulin resistance (IR) and type 2 diabetes (T2D). It has been reported that IR and T2D are associated with an increased ratio of 12α/non-12α-hydroxylated BAs in the circulating BA pool. It is, however, unknown whether the improvement of insulin sensitivity inversely affects BA composition in humans.

Chronic Stress Related to Cancer Incidence, including the Role of Metabolic Syndrome Components.

Epidemiological results on the link between chronic stress and cancer initiation have been inconsistent. This study examined the relation between chronic biological stress, indicated as hair cortisol (HairF) and hair cortisone (HairE), and cancer incidence, adjusting for metabolic syndrome (MetS) components. We analyzed HairF and HairE samples from 6341 participants from the population-based cohort Lifelines in 2014.

GNB1 and obesity: Evidence for a correlation between haploinsufficiency and syndromic obesity.

Most patients with GNB1 encephalopathy have developmental delay and/or intellectual disability, brain anomalies and seizures. Recently, two cases with GNB1 encephalopathy caused by haploinsufficiency have been reported that also show a Prader-Willi-like phenotype of childhood hypotonia and severe obesity. Here we present three new cases from our expert centre for genetic obesity in which GNB1 truncating and splice variants, probably leading to haploinsufficiency, were identified.

Improved Physical and Mental Health After a Combined Lifestyle Intervention with Cognitive Behavioural Therapy for Obesity.

Background: Obesity is a multifactorial, chronic, progressive disease associated with decreased health-related quality of life, comorbidities, and increased mortality risk. Lifestyle interventions, focusing on dietetics, physical exercise, and behavioral therapy, are a cornerstone of therapy. Despite this very multidisciplinary treatment approach, the definition of treatment success is often based only on a weight loss of ≥ 5%.

Levels of hormones regulating appetite and energy homeostasis in response to a 1.5-Year combined lifestyle intervention for obesity.

Weight loss can induce changes in appetite-regulating hormone levels, possibly linked to increases in appetite and weight regain. However, hormonal changes vary across interventions. Here, we studied levels of appetite-regulating hormones during a combined lifestyle intervention (CLI: healthy diet, exercise and cognitive behavioral therapy).

Successful naltrexone-bupropion treatment after several treatment failures in a patient with severe monogenic obesity.

We describe the therapeutic journey of a 33-year-old patient with early-onset obesity (BMI 56.7 kg/m) and hyperphagia due to a likely pathogenic heterozygous () gene variant. She was unsuccessfully treated with several intensive lifestyle interventions, gastric bypass surgery (-40 kg weight loss, followed by +39.

Glucocorticoids, stress and eating: The mediating role of appetite-regulating hormones.

Disrupted hormonal appetite signaling plays a crucial role in obesity as it may lead to uncontrolled reward-related eating. Such disturbances can be induced not only by weight gain itself but also by glucocorticoid overexposure, for example, due to chronic stress, disease, or medication use. However, the exact pathways are just starting to be understood.

Monocyte adaptations in patients with obesity during a 1.5 year lifestyle intervention.

Background: Obesity is associated with chronic, low-grade inflammation, which is reflected in altered peripheral blood monocyte characteristics. The aim of this study was to analyze the monocyte subset composition (classical (CM), intermediate (IM) and non-classical monocytes (NCM)), and their inflammatory marker profile (CD14, CD16, CD36, CD45, CD64, CD300e, HLA-DR) in individuals with obesity during a 1.5 year combined lifestyle intervention (CLI), comprising healthy nutrition, increased exercise and behavioral changes.

Obesity and Hyperphagia With Increased Defective ACTH: A Novel POMC Variant.

Objective: Patients with pro-opiomelanocortin (POMC) defects generally present with early-onset obesity, hyperphagia, hypopigmentation and adrenocorticotropin (ACTH) deficiency. Rodent models suggest that adequate cleavage of ACTH to α-melanocortin-stimulating hormone (α-MSH) and desacetyl-α-melanocortin-stimulating hormone (d-α-MSH) by prohormone convertase 2 at the KKRR region is required for regulating food intake and energy balance.

Methods: We present 2 sisters with a novel POMC gene variant, leading to an ACTH defect at the prohormone convertase 2 cleavage site, and performed functional studies of this variant.

Variation in glucocorticoid sensitivity and the relation with obesity.

Increasing evidence points to a relation between increased glucocorticoid (GC) exposure and weight gain. In support, long-term cortisol measurements using hair analysis revealed that many individuals with obesity appear to have cortisol values in the high physiological range. The mechanisms behind this relationship need to be determined in order to develop targeted therapy to reach sustainable weight loss in these subgroups.

Hair cortisol, obesity and the immune system: Results from a 3 year longitudinal study.

Objectives: Higher long-term glucocorticoid levels, measured in scalp hair (HairGC), are associated with obesity. This may represent the state of obesity (perhaps interrelated with chronic immune activation), but could also promote further weight gain. We studied whether hair cortisol (HairF) and hair cortisone (HairE) predict changes in body mass index (BMI) and waist circumference (WC) over time, and assessed the association between HairGC and common immune parameters.

Effects of glucagon-like peptide-1 analogue treatment in genetic obesity: A case series.

Obesity is highly prevalent and comes with serious health burden. In a minority, a genetic cause is present which often results in therapy-resistant obesity. Liraglutide is a glucagon-like peptide-1 (GLP-1) analogue, which has beneficial effects on satiety and weight in common obesity.

In adults with obesity, copeptin is linked with BMI but is not associated with long-term exposure to cortisol and cortisone.

Context: Obesity and cardiometabolic diseases are associated with higher long-term glucocorticoid levels, measured as scalp hair cortisol (HairF) and cortisone (HairE). Cardiometabolic diseases have also been associated with copeptin, a stable surrogate marker for the arginine-vasopressin (AVP) system. Since AVP is, together with corticotropin-releasing hormone (CRH) an important regulator of the hypothalamic-pituitary adrenal axis (HPA axis), we hypothesize that AVP contributes to chronic hypercortisolism in obesity.

A comprehensive diagnostic approach to detect underlying causes of obesity in adults.

Obesity is a worldwide growing problem. When confronted with obesity, many health care providers focus on direct treatment of the consequences of adiposity. We plead for adequate diagnostics first, followed by an individualized treatment.

Stress and Obesity: Are There More Susceptible Individuals?

Purpose Of Review: Stress has long been suspected to be interrelated to (abdominal) obesity. However, interindividual differences in this complex relationship exist. We suggest that the extent of glucocorticoid action partly explains these interindividual differences.

Decreased physical activity, reduced QoL and presence of debilitating fatigue in patients with Addison's disease.

Background: Health-related quality of life in patients with Addison's disease has been assessed in various European countries, indicating a reduced quality of life. However, no studies have addressed the impact of Addison's disease on physical activity.

Objective: The aim of this study was to investigate the quality of life in Dutch patients with Addison's disease particularly regarding the presence of fatigue and the ability to be physically active.

Incidence of adrenal crisis in patients with adrenal insufficiency.

Background: An adrenal crisis (AC) is a potential life-threatening event in patients with adrenal insufficiency (AI). This study aims to determine the incidence, causes, and risk factors of AC in AI.

Methods: Patients with AI diagnosed and treated at the University Medical Center Utrecht for the past 30 years were identified, and all medical records were assessed by two independent investigators.
