PURPOSE: Fat mass (FM) is a source of adipocytokines, with both positive and negative bone consequences. We aimed to investigate the role of body composition and adipokines as predictive factors for bone mass in women. METHODOLOGY: This cross-sectional study included 93 women (38 premenopausal and 55 postmenopausal). Bone mineral density (BMD) and body composition were assessed by dual-energy X-ray absorptiometry. Serum levels of leptin, adiponectin, resistin, and also of the phosphocalcic markers parathormone and vitamin D were measured...

The literature on thyroid autoimmunity has identified many potential factors at play for the initiation and progression of autoimmune thyroid diseases. These factors include genetic susceptibility, environmental factors, some drugs, iodine and selenium, infection, molecular mimics, and immune system defects. The sheer number of feasible factors makes sorting out the necessary agents from the fellow travelers difficult. In addition, many of these factors have the capability to interact-further confusing the picture...

PURPOSE: Current fracture risk assessment options in men call for improved evaluation strategies. Recent research directed towards non-classic bone mass determinants have often yielded scarce and conflicting results. We aimed at investigating the impact of novel potential bone mass regulators together with classic determinants of bone status in healthy young and middle-aged men. METHODS: Anthropometric measurements, all-site bone mineral density (BMD) and body composition parameters assessed by dual-energy X-ray absorptiometry and also serum concentrations of (1) the adipokines leptin and resistin, (2) vitamin D and parathormone (PTH), (3) sex hormone binding globulin (SHBG), total testosterone and estradiol (free testosterone was also calculated) and (4) C-terminal telopeptide of type I collagen (CTx) were obtained from 30 apparently healthy male volunteers aged 20-65 years enrolled in this cross-sectional study...

A growing interest in the role of vitamin D in metabolic diseases led us to study the relationships between 25-hydroxyvitamin D₃ (25(OH)D₃) and the profiles of selected adipokines in type 2 diabetic (T2DM) patients. The study comprised 92 type 2 diabetics divided into quartiles regarding 25(OH)D₃ concentration. Each group was divided into male and female subgroups. All the studied patients had their anthropometric and biochemical parameters determined. Plasma 25-hydroxyvitamin D₃ concentration was determined by HPLC, while the selected adipokines (leptin, adiponectin, resistin and visfatin) by ELISA methods...

Adipose tissue is involved in the etiology of postmenopausal breast cancer, possibly through increased sex steroid hormone production, inflammation, and altered adipokines. Vitamin D may affect these pathways but its effect on gene expression in different tissues has not been examined. Within a double-blind, 12-month placebo-controlled randomized trial, we compared 2000 IU/day oral vitamin D3 supplementation ( N  = 39) vs. placebo ( N  = 40) on the expression of 5 genes in breast and adipose tissue in overweight/obese postmenopausal women (50-75 years)...

Androgens and estrogens play a key role regarding sexual life and reproduction. Along with hypotestosteronemia, obese men exhibit a 2-fold increase in estradiol concentration, adversely infl uencing these parameters. Estrogens and adipokines also infl uence bone metabolism, exerting a direct effect on vitamin D, calcium homeostasis and bone health. Bariatric procedures normalize some sex hormones, and may reverse several obesity-related conditions. Estrogens levels may remain elevated postoperatively, and despite its protective effect on the skeleton, bariatric patients are more prone to fractures when compared to the general population...

Obesity is recognized as a state of chronic low-grade systemic inflammation due to adipose tissue macrophage infiltration and production of proinflammatory adipokines. Decreased vitamin D status is associated with obesity. The specific aim of the present study is to investigate the effects of vitamin D on obesity-induced adipose tissue inflammation. Male Sprague-Dawley rats were randomized and fed a normal diet (NOR, 1000 IU vitamin D/kg diet), a 45% high-fat diet (HF, 1000 IU vitamin D/kg diet), or a 45% high-fat diet containing 25 IU vitamin D/kg diet (HF+LVD) for 12 weeks...

Adipose tissue has been long recognized as secreting various endocrine factors. Emerging evidence demonstrates that adipokines play a role in modulating systemic mineral homeostasis through endocrine loops involving interleukin-6, leptin, and now also adiponectin, which all interact with FGF23 and vitamin D and thereby change the renal control of calcium and phosphate metabolism. Understanding these regulatory loops may shed light on a complex interorgan crosstalk controlling mineral homeostasis and its dysregulation in diseases associated with obesity...

Vitamin D is an important steroid hormone, which has a wide biological effect and is the protective factor against cardiovascular disease and other diseases. At present, the etiology and pathogenesis of Kawasaki disease (KD) remain unknown, but recent studies have shown that vitamin D insufficiency or deficiency is associated with KD. Vitamin D insufficiency or deficiency may affect KD via its influence on inflammatory response, adipokine, endothelial function, platelet function, and DNA methylation and increase the risk of coronary artery lesions...

Fatigue impacts 80-90% of patients with systemic lupus erythematosus (SLE), and an incomplete understanding of fatigue mechanisms limits effective treatment. Disease activity indices and laboratory markers inconsistently correlate with fatigue severity in SLE populations. Identification of fatigue biomarkers has important implications for understanding pathogenesis and defining novel therapeutic targets, but a paucity of evidence exists for fatigue biomarkers in SLE. The evidence for adipokines, reduced glutathione, iron deficiency, and vitamin D as potential biomarkers for SLE-related fatigue are reviewed...
