Spinal cord injury (SCI) has been associated with a marked increase in bone loss. This study analysed the effect of Wnt signalling antagonists (sclerostin and DKK-1) and their relationship with bone turnover markers and BMD evolution in patients with a recent SCI.Methods: Patients with a recent complete motor SCI (AIS A or B); (<6 months) were prospectively included. Bone turnover markers (bone formation: P1NP, bone AP; bone resorption: sCTx), Wnt an...

Spinal cord injury (SCI) has been associated with marked bone loss and an increased risk of fractures under the SCI level. The aim of the study was to analyze the effect of recent complete SCI on bone turnover and bone mineral density (BMD) evolution and factors related to bone loss.Methods: Prospective study including patients with complete motor SCI (ASIA A or B) (<6 months). Bone turnover markers (bone formation: P1NP, bone ALP and resorption: sCT...

The aims of this study were to analyze the role of the regulators of bone remodeling, OPG and RANKL, in the bone loss associated with recent spinal cord injury (SCI) as well as the effect of antiosteoporotic therapy with denosumab in these bone regulators in a prospective study.Patients and methods: Twenty-three male patients (aged 18–67 years (mean 36±16 years)) with recent (<6 months) complete SCI were prospectively included (43.5% parapl...

Dietary Ca insufficiency is a common finding, independently of socio-economic status. A low Ca intake (CaI) increases bone turnover leading to bone loss. This effect becomes more important during estrogen withdrawing. We previously found that a mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS) enhances Ca and P absorption (Abs), being a suitable tool to optimize its bioavailability and consequently bone health. The present study evaluated the effect of ...

It has suggested that BGP is inversely related to body fat. BGP appears to regulate energetic metabolism through the insulin receptor signaling pathway in the osteoblast, which affects bone resorption and BGP activity. Fat tissue is an endocrine organ that secretes different hormones and growth factors; several of them affect bone remodeling and insulin secretion. The present report comparatively studied total BGP levels, glucose homeostasis and body fat mass in spontaneous ob...

A mixture of Galacto-oligosaccharides (GOS) and Fructooligosaccharides (FOS) are added to commercial infant formula to promote an intestinal microbiota similar to that prevalent in breast-fed infants to improve Ca bioavailability and general health, but their mechanisms are under debate.Our objective was to evaluate the beneficial effects of the mixture of GOS/FOS added to infant formulae, on the absorption of Ca, Mg and P of a low Ca diet. Changes in in...

During early life undernutrition impairs normal weight and height gain that affects bone health. During recovering it is required an extra-amount of Ca to ensure the high demands of bone mineralization. A mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS) would be a useful tool to increase mineral intestinal absorption to enhancing the amount of Ca to be retained into bone. Our objective was to evaluate, in an experimental model of protein restriction (P...
