UNLABELLED In a randomized controlled study, we investigated the effect of treatment with intravenous neridronate in prepubertal children with OI. Our study suggests that quarterly intravenous infusions of the bisphosphonate significantly raise the rate of increase in BMD at both the spine and hip, the projected area of the lumbar vertebrae, and height.(More)
Bone involvement is frequent in patients with systemic mastocytosis. Osteoporosis is the most prevalent bone manifestation, but diffuse osteosclerosis or focal osteolytic or osteosclerotic lesions are not infrequent. The risk of osteoporotic fractures is high, especially at the spine and in men. Routine measurements of bone mineral density and vertebral(More)
Bone involvement, mainly osteoporosis but also osteosclerosis, is frequent in patients with indolent systemic mastocytosis (ISM). The recent characterization of the canonical Wnt/β-catenin pathway in the regulation of bone remodeling provided important insights for our understanding of the pathophysiology of a number of conditions. The regulation of Wnt(More)
CONTEXT The effect of teriparatide (TPD) on bone turnover is initially exuberant but then diminishes. TPD is thought to stimulate bone formation by down-regulating the expression of specific Wnt antagonists, such as of sclerostin and Dickkopf-1 (DKK1). OBJECTIVE Our objective was to determine whether long-term treatment with TPD is associated with(More)
The bone mass benefits of antiresorbers in postmenopausal osteoporosis are limited by the rapid coupling of decreasing bone resorption with bone formation. Wnt signaling is involved in this coupling process during treatment with bisphosphonates, whereas its role during treatment with the anti-receptor activator of NF-κB ligand (RANKL) antibody denosumab is(More)
OBJECTIVE We systematically assessed bone mineral density (BMD), bone turnover markers (BTM), and fractures in a large cohort of patients with Indolent Systemic Mastocytosis (ISM). METHODS Eighty-two patients (mean age 48 years, 37 women) with ISM were studied. BMD was measured by dual X-ray absorptiometry at the lumbar spine and proximal hip. The serum(More)
BACKGROUND Osteoporosis is the prevalent manifestation of bone involvement in patients with systemic mastocytosis. Mastocytosis-related osteoporosis is characterized by both absolute and relative prevalence of osteoclastic activity, consistent with the positive results reported in small series of patients with antiresorptive drugs, such as bisphosphonates.(More)
Mastocytosis is a rare condition characterized by abnormal mast cell proliferation and a broad spectrum of manifestations, including various organs and tissues. Osteoporosis is one of the most frequent manifestations of systemic mastocytosis, particularly in adults. Osteoporosis secondary to systemic mastocytosis is a cause of unexplained low bone mineral(More)
Vitamin D deficiency is extremely common among elderly subjects and it has been associated with poor bone health, and to a number of other conditions. The ideal 25-hydroxy-vitamin D [25(OH)D] concentration, reflecting the size of vitamin D deposits, are generally retained those not associated with any marginal increase in serum parathyroid hormone (PTH).(More)
Neridronate is an aminobisphosphonate, licensed in Italy for the treatment of osteogenesis imperfecta (OI) and Paget's disease of bone (PDB). A characteristic property of neridronate is that it can be administered both intravenously and intramuscularly, providing a useful system for administration in homecare. In this review, we discuss the latest clinical(More)
