Although X-linked hypophosphatemic rickets (XLH) is characterized by hypophosphatemia leading to a generalized mineralization defect with rickets (and/or osteomalacia), densitometric studies point towards a tendency towards an elevated bone mineral density (BMD). The aim of this cross-sectional in vivo study was to assess bone geometry, volumetric BMD (vBMD), microarchitecture and estimated bone strength using high-resolution peripheral quantitative computed tomograph...

Osteogenesis imperfecta (OI) is a systemic connective tissue caused by mutations in collagen type 1 related genes. Patients with OI suffer from multiple fractures and various degrees of growth deficiency and bone deformity. Other symptoms are early hearing loss, abnormal dental tissue and hypermobility. It is not known whether the systemic effect of a defect collagen type 1 influences the quality of life in people with OI. We aimed to investigate health related quality of life...

Osteogenesis imperfecta (OI) is a hereditary disease with a generalized involvement of the connective tissue caused by collagen type 1 mutations. The clinical appearance is broad with fractures as the key symptom. Only few genotype–phenotype correlations have been established. We aim to characterize the Danish OI population thoroughly including DXA and HRpQCT, anthropometry, patient history, and genetic background.This cross-sectional study includes...

Recent studies have revealed hypoparathyroidism to be a disease associated with an increased risk of a number of co-morbidities including seizures, renal diseases, and infections as well as an impaired quality of life. In the summer of 2015, the first international guideline on treatment of hypoparathyroidism in the adults was published by the European Society of Endocrinology. The guideline is based on a systematic literature search for which available evidence was synthesize...

Conventional treatment of hypoparathyroidism with calcium and active vitamin D analogues causes a high renal calcium excretion and over-mineralized bone.We studied 62 patients with hypoPT randomized to 6 months of treatment with either parathyroid hormone (PTH(1-84)) 100 μg/d s.c. or similar placebo, administered as an add-on therapy. Forty-two of the patients had follow-up test performed after 2.5 years; 9 patients had continued daily PTH treatment...

PTH replacement therapy in hypoparathyroidism (hypoPT) has become more accepted after proving successful in several clinical studies. Intact PTH (PTH1–84) was in 2012 withdrawn, leaving teriparatide (PTH1–34) the only therapeutic option available.All patients with postoperative HypoPT who changed medication from PTH1–84 (100 μg) to PTH1–34 (20 μg), after at least 12 months of conve...

Background: Non-surgical hypoparathyroidism (NS-HypoPT) and pseudohypoparathyroidism (Ps-HypoPT) are both rare diseases, with a prevalence of 2/100.000 and 1/100.000, respectively.Studies on Quality of Life, QoL, are sparse, but studies have shown an increased risk of fatigue and depression.Methods: Using the Danish version of SF36v2 and WHO-5 Well Being Index, we investigated the physical and mental QoL among patients with NS-Hypo...

Context: Impairment of muscle function and strength in patients with primary hyperparathyroidism (PHPT) is rarely addressed although decreased muscle function may contribute to increased fracture risk in PHPT.Objective: We aimed to assess changes in muscle strength, muscle function, postural balance, quality of life (QoL), and well-being during treatment with vitamin D or placebo before and after parathyroidectomy (PTX) in PHPT patients.<p class="abs...

Total thyroidectomy causes postsurgical hypothyroidism (HypoT). Besides HypoT, patients may also develop hypoparathyroidism (HypoPT).The aim of the study was to assess Quality of Life (QoL), muscle function, and bone indices in patients with postsurgical hypothyroidism and hypoparathyroidism (HypoT+PT) as compared to patients with postsurgical HypoT and healthy controls.Age and gender matched patients on treatment for HypoT+PT and ...
