Introduction: The interaction between RANK/RANKL is critical for the regulation of osteoclastogenesis and bone resorption. Inhibition of this interaction helps restore the balance between bone resorption and formation. ALX-0141, a novel biological agent (Nanobody) that specifically targets RANKL, was studied in a Phase I trial to assess the safety, tolerability, immunogenicity and PK after single injection.Methods: Forty-two healthy postmenopausal women ...

Fibrodysplasia ossificans progressiva (FOP) is a rare, autosomal dominant disorder characterized by heterotopic ossification (HO) in muscles, ligaments and tendons. Flare-ups often precede formation of HO, resulting in immobilized joints. Recently, it has been shown that [18F]NaF PET/CT could identify early ossifying disease activity during flare-ups. HO may progress without signs of flare-up, but its underlying physiology is not understood. We wondered whether [18F]NaF PET/CT...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic cause of renal failure. Data from adult ADPKD population show increased fibroblast growth factor 23 (FGF23) levels while circulating Klotho levels decrease, with a low TmP/GFR even in patients with normal renal function. Moreover, in ADPKD animal models, cyst lining renal cells were demonstrated to produce FGF23, although the animals displayed FGF23 resistance. No data are available in a paediatr...

Objective: To study the trends in prescription of different anti-osteoporotic drugs (AOD) in the UK population aged 50 years or above from 1990 till 2012.Methods: Retrospective observational study using the CPRD data link representative for the total UK population. The incidence of prescription of a specific AOD was calculated by dividing the number of prescriptions by the total person-years (py) of follow-up.Results: AOD prescript...

Objectives: impairment of bone mineral density (BMD) is a complication of childhood cancer treatment. A comprehensive review on the occurrence of impaired BMD in childhood cancer survivors (CCS), and which disease subgroups are at risk has never been pursued so far. The aim of this study was to summarize all knowledge on BMD status and associated determinants in long-term adult childhood cancer survivors (CCS) based on available literature.Methods: an el...

Introduction: Despite similarities in upfront treatment, impairment of bone mineral density(BMD) varies in long-term adult survivors of childhood cancer (CCS). We studied for the first time whether genetic variation is involved in impairment of BMD in adult long-term CCS.Method: This cross-sectional single-center cohort study included 334 adult CCS (median follow-up time: 15.2 years (range 5.1–39.8); median age at follow-up: 26.1 years (range 18.1&#...

Introduction: Osteocalcin (OC) is a marker of bone formation but also seems to play a hormonal role in the regulation of glucose and energy metabolism. Recently, an association of BMI with a haplotype composed of three single nucleotide polymorphisms (SNPs) in the gene for OC, located on chromosome 1q22, was observed in ethnically homogeneous European pedigrees.Aim: The aim of the study was to test the association of these three polymorphisms in the gene...

After trauma or carious lesion dental pulp healing is difficult to predict. In addition systemic diseases like diabetes mellitus can impair the regenerative capacity. New regenerative strategies target prolyl hydroxylase (PHD) by pharmacological inhibitors to stimulate hard and soft tissue healing. PHD inhibitors such as L-mimosine (L-MIM) induce vascular endothelial growth factor (VEGF) production by promoting angiogenesis. However, it is unclear if L-MIM is a feasible tool t...
