Background: Pathogenic mutations in thyroid hormone receptor interactor 11 (TRIP11) have previously been associated with achondrogenesis1A, a lethal autosomal recessive skeletal dysplasia. Recent findings have suggested that hypomorphic mutations of TRIP11 result in odontochondrodysplasia (ODCD), a rare syndrome associated with spondylometaphyseal dysplasia and dentinogenesis imperfecta.Presenting problem: This is the case of a term female born to non-co...

Background: Pediatric hypoparathyroidism is an orphan disease. Conventional management combines native and active vitamin D, calcium supplementation and sometimes phosphate binders. The use of teriparatide has been reported both in adults (daily or bi-daily subcutaneous infusions) and in children (rather continuous subcutaneous infusion) as second-line therapy.Methods: We present as median (min-max) the results of a retrospective single-centre review of ...

Aim: The aim of the study was to evaluate the usefulness of the fracture risk evaluated through the FRAX® model based only on the clinical risk factors as a screening tool for identify the target population for treatment in osteoporosis.Materials and methods: Two hundred and seventy-six postmenopausal women treatment naive referred to two different endocrinology departments for osteoporosis between 2009 and 2011 were evaluated. The FRAX® model ...

Quantitative Computed Tomography (QCT) can be performed with different protocols. We investigated whether selection of spatial resolution, reconstruction method, and scanner type have an impact on measured treatment effects for different bone compartments.Methods: In a multi-center study, a group of 50 men, age 55.1 (range 25–78) undergoing 18 months of either osteoanabolic (n=25) or antiresorptive treatment (n=25) were scanned wit...

Background: Advancing maternal age at childbirth has been associated with a higher risk of pregnancy complications and with adverse short-term and long-term offspring health outcomes, but little is known about the effects of increasing maternal age on offspring bone acquisition.Objective: To investigate associations of maternal age at childbirth with offspring bone parameters in healthy men at the age of peak bone mass.Methods: We ...

Although it is well established, that quality of life improves in patients after lung transplantation (LTx), severe musculoskeletal complications may develop. The aim of this study was to evaluate differences in the muscle markers Myostatin and Follistatin and the bone markers Dickkopf-1 (DKK1), Sclerostin (SOST) and Periostin between LuTx recipients and healthy controls. From 38 LTx patients blood samples were taken when discharged from hospital (LTx1) and 6-9 months after di...

Hypogonadism is common in cardiac transplant (CTX) patients and exerts negative effects on bone but also on libido and quality of life.We investigated whether testosterone replacement therapy (TRT) has any positive effects on bone mass, fracture incidence, and quality of sex life when administered in addition to ibandronate (IBN) in hypogonadal CTX recipients. 52 male patients entered the study and received IBN (quarterly 2 μg i.v.). 60% of the pati...

Bone marrow is the main hematopoietic organ of adults. There, hematopoietic stem cells from which all hematopoietic lineages can be generated are preferentially homing. Importantly, bone provides niches for early B cell differentiation and survival of long-lived plasma cells that produced antibodies. Thus, that perturbing bone homeostasis might impact B cell function and antibody production is a highly relevant hypothesis for patients receiving antiresorptive drugs.<p clas...

Objectives: This study aims to evaluate and compare the preferences of patients and health care professionals for osteoporotic drug treatment.Materials and methods: A discrete choice experiment was conducted among patients and health care professionals (general physicians, rheumatologists, and geriatricians) in Belgium. Participants were asked to choose between two hypothetical unlabelled drug treatments (and an opt-out option) that vary in several attri...
