“…Adipose tissue distribution is heavily influenced by sex, with sex-related patterns becoming apparent during puberty. However, in obese female children, a BMI-related increase in androgens [24,25] may favour central adiposity. In addition, obese female children have a greater degree of obesity-induced insulin resistance [26], and the compensatory hyperinsulinaemia may further facilitate accumulation of visceral fat [27].…”

Obese asthma is characterised by infiltration of adipose tissue by activated macrophages and mast cells. The aim of this study was to examine the age and sex effects of immunometabolism in obese asthma.Obese and non-obese asthmatic children and adults underwent spirometry, body composition assessment by dual energy X-ray absorptiometry and measurement of serum soluble CD163 (sCD163), tryptase, C-reactive protein (CRP) and other adipocytokines.Plasma CRP ( p<0.01) and leptin ( p<0.01) were elevated in obese asthmatic adults, and sCD163 ( p=0.003) was elevated in obese asthmatic children. We observed significantly higher sCD163 in obese female children compared to obese female adults and male children, and higher CRP in obese female adults compared to obese male children and adults. Serum tryptase concentrations were not significantly different across age groups. sCD163 positively correlated with the proportion of android fat in obese female children (r=0.70, p=0.003) and obese female adults (r=0.65, p=0.003). In obese female children, sCD163 was inversely associated with forced expiratory volume in 1 s % predicted (r=−0.55, p=0.02) and was positively associated with the Asthma Control Questionnaire (r=0.57, p=0.02).Obese children with asthma have sex-specific macrophage activation, which may contribute to worse asthma control and lung function. The heterogeneous systemic inflammatory profile across age and sex suggests the existence of sub-phenotypes in obese asthma at the molecular level. @ERSpublications Macrophage activation is a determinant of pro-inflammatory effects of immunometabolism in childhood obese asthma

The aim of this pilot study is to evaluate the stress among underweight, overweight and obese undergraduate medical students using BMI as a primary indicator. A total of 234 students were selected for the Study comprising of 143 females and 91 males, after obtaining the written informed consent. Participants were classified into overweight, obesity and underweight according to WHO guidelines. DASS-42 was used to assess depression, anxiety and stress. We have not observed significant difference in depression, anxiety and stress among normal, obese, over weight and underweight females and males. We recommend further detailed, multi center studies in this area.

“…Usually, for the hormonal assessment of CAH, several steroids have to be considered as a pattern in parallel, e.g., 17-hydroxyprogesterone, androstenedione, cortisol in 21OHD [28]. We here established MoM cutoffs for “diagnostic single-steroid MoMs” predicting 21OHD (17-hydroxyprogesterone > 3.78; 21-deoxycortisol > 12.28) and 11OHD (11-deoxycortisol > 13.18).…”

Background/Aims: The high complexity of pediatric reference ranges across age, sex, and units impairs clinical application and comparability of steroid hormone data, e.g., in congenital adrenal hyperplasia (CAH). We developed a multiples-of-median (MoM) normalization tool to overcome this major drawback in pediatric endocrinology. Methods: Liquid chromatography tandem mass spectrometry data comprising 10 steroid hormones representing 905 controls (555 males, 350 females, 0 to > 16 years) from 2 previous datasets were MoM transformed across age and sex. Twenty-three genetically proven CAH patients were included (21-hydroxylase deficiency [21OHD], n = 19; 11β-hydroxylase deficiency [11OHD], n = 4). MoM cutoffs for single steroids predicting 21OHD and 11OHD were computed and validated through new, independent patients (21OHD, n = 8; adrenal cortical carcinoma, n = 6; obesity, n = 40). Results: 21OHD and 11OHD patients showed disease-typical, easily recognizable MoM patterns independent of age, sex, and concentration units. Two single-steroid cutoffs indicated 21OHD: 3.87 MoM for 17-hydroxyprogesterone (100% sensitivity and 98.83% specificity) and 12.28 MoM for 21-deoxycortisol (94.74% sensitivity and 100% specificity). A cutoff of 13.18 MoM for 11-deoxycortisol indicated 11OHD (100% sensitivity and 100% specificity). Conclusions: Age- and sex-independent MoMs are straightforward for a clinically relevant display of multi-steroid patterns. In addition, defined single-steroid MoMs can serve alone as predictors of 21OHD and 11OHD. Finally, MoM transformation offers substantial enhancement of routine and scientific steroid hormone data exchange due to improved comparability.

Steroid Hormone Profiles in Prepubertal Obese Children Before and After Weight Loss

Abstract: In obese prepubertal children, the increased androgens, mineralocorticoid precursors, and glucocorticoids were responsive to weight loss in contrast to DHEAS, suggesting that DHEAS does not seem to be regulated by changes in body mass index.
