Magnetic resonance imaging based assessment of bone microstructure as a non-invasive alternative to histomorphometry in patients with chronic kidney disease.

Chronic kidney disease (CKD) adversely affects bone microarchitecture and increases fracture risk. Historically, bone biopsy has been the 'gold standard' for evaluating renal bone disease but is invasive and infrequently performed. High-resolution magnetic resonance imaging (MRI) quantifies bone microarchitecture noninvasively. In patients with CKD, it has not been compared with results derived from bone biopsy or with imaging using dual energy X-ray absorptiometry (DXA).

A quest for clarity in bone erosion: The role of sequestosome 1 in Paget's disease of bone.

Alterations in the gene are a putative cause of Paget's disease of bone, yet results are conflicting about how these mutations impact osteoclasts, the cell type believed to be the main pathological contributor. In this issue of JBC, Zach provide important new evidence that the protein encoded by , p62, negatively regulates osteoclastogenesis and demonstrate that aged p62-deficient mice develop bone phenotypes similar to those of Paget's disease. These findings help to clarify the role of this important pr...

A novel anti-osteoporotic agent that protects against postmenopausal bone loss by regulating bone formation and bone resorption.

Postmenopausal osteoporosis is a bone metabolism disease that is caused by an imbalance between bone-resorbing osteoclast and bone-forming osteoblast actions. Herein, we describe the role of troxerutin (TRX), a trihydroxyethylated derivative of rutin, in ovariectomy (OVX)-induced osteoporosis and its effects on the regulation of osteoclasts and osteoblasts.

Feasibility of quantitative ultrasonography for the detection of metabolic bone disease in preterm infants - systematic review.

Metabolic bone disease of prematurity is characterised by disordered bone mineralisation and is therefore an increased fracture risk. Preterm infants are especially at risk due to incomplete in utero bone accretion during the last trimester. Currently, diagnosing metabolic bone disease mainly relies on biochemistry and radiographs. Dual-energy x-ray absorptiometry and quantitative ultrasound (US) are used less frequently. However, biochemical measurements correlate poorly with bone mineralisation and althou...

Paget's disease of bone: diagnosis and treatment..

Paget's disease of bone is a common bone disorder characterized by disorganized bone remodeling. The most likely etiology is a slow paramyxoviral viral infection in genetically susceptible individuals, however the exact cause is unknown. Enhanced bone resorption due to and increased activity of osteoclasts recruits numerous osteoblasts to resorption sites with large quantities of new bone matrix produced as a result. The accelerated bone resorption and formation are not as closely coupled as in a healthy bo...

Preventing and repairing myeloma bone disease by combining conventional antiresorptive treatment with a bone anabolic agent in murine models.

Multiple myeloma is a plasma cell malignancy, which develops in the bone marrow and frequently leads to severe bone destruction. Current antiresorptive therapies to treat the bone disease do little to repair damaged bone; therefore, new treatment strategies incorporating bone anabolic therapies are urgently required. We hypothesized that combination therapy using the standard of care antiresorptive zoledronic acid (Zol) with a bone anabolic (anti-TGFβ/1D11) would be more effective at treating myeloma-induc...

Regulation of Skeletal Homeostasis.

Landmark advances in skeletal biology have arisen mainly from the identification of disease-causing mutations and the advent of rapid and selective gene targeting technologies to phenocopy human disease in mice. Here, we discuss work on newly identified mechanisms controlling the remodeling of bone, communication of bone cells with cells of other lineages, and crosstalk between bone and vital organs, as these relate to the therapeutic targeting of the skeleton.

Deterioration of Cortical Bone Microarchitecture: Critical Component of Renal Osteodystrophy Evaluation.

Cortical bone is a significant determinant of bone strength and its deterioration contributes to bone fragility. Thin cortices and increased cortical porosity have been noted in patients with chronic kidney disease (CKD), but the "Turnover Mineralization Volume" classification of renal osteodystrophy does not emphasize cortical bone as a key parameter. We aimed to assess trabecular and cortical bone microarchitecture by histomorphometry and micro-CT in patients with CKD G5 and 5D (dialysis).

Bone Biopsy Results in Chronic Kidney Disease: a Single-Center Experience.

Although bone histology remains the diagnostic standard in renal osteodystrophy (ROD), biomarkers are used more commonly. Data comparing bone biopsy results and biomarkers of bone metabolism remain sparse.

Response to Long-term Vitamin D Therapy for Bone Disease in Children With Sickle Cell Disease.

Patients with sickle cell disease (SCD) are at risk for bone fragility from multiple factors including vitamin D deficiency. To date, no studies have evaluated the efficacy and safety of long-term vitamin D therapy for bone disease in children with SCD. We report a cohort of 4 children with SCD found to have severe vitamin D deficiency, secondary hyperparathyroidism, and abnormal bone mineral density treated with monthly high-dose oral cholecalciferol over 2 years. All patients exhibited a positive response...

Clinical utility of bone markers in various diseases.

Measurements of bone markers (BMs) in peripheral blood or urine are a pivotal part of bone research within modern clinical medicine. In recent years the use of BMs increased substantially as they can be useful either to diagnose bone (related) disease and to follow its natural history, but also to monitor the effects of interventions. However, the use of BMs is still complicated mainly due to (pre)analytical variability of these substances, limited accessibility of assays, variable cut-off values in differe...

Adipokines and bone status in a cohort of anorexic patients.

Bone loss in anorexia nervosa (AN) is multifactorial; its mechanisms are not yet clearly understood and may vary depending on disease duration and severity. To determine to what extent adipokines may be involved in the bone alterations found in anorexic patients, we evaluated plasma levels for leptin, adiponectin and Pref-1 against other clinical and biological parameters in a population of anorexic patients split according to weight and bone status.

Comparison of bone turnover markers in peripheral blood and bone marrow aspirate.

Bone remodeling takes place in the bone marrow environment. We investigated if levels of bone turnover markers (BTMs) differ between bone marrow and peripheral blood, if the bone marrow is an independent compartment, and how well the measurements in bone marrow correlate with bone mineral density.

Alterations of Inflammatory and Matrix Production Indices in Celiac Disease With Low Bone Mass on Long-term Gluten-free Diet.

A clinically meaningful impairment of bone mass secondary to malabsorption is frequent in untreated celiac disease. In adult patients, a rigorous gluten-free diet (GFD) significantly improves, but does not always normalize, bone mineral density (BMD). The reason for this marginal response is unclear. Accordingly, we evaluated the role of both local and systemic factors for bone loss in celiac patients on long-term GFD.

First-in-Human Phase I Study of MBC-11, a Novel Bone-Targeted Cytarabine-Etidronate Conjugate in Patients with Cancer-Induced Bone Disease.

Results are consistent with MBC-11 targeting and treating cancer-induced bone lesions by concentrating cytarabine and etidronate at the site of disease.MBC-11 was well tolerated, with an maximum tolerated dose of 5 mg/kg per day and myelosuppression as the principal toxicity.Treatment significantly reduced cancer cell activity in over half of bone lesions detected at baseline.MBC-11 pharmacokinetic and pharmacodynamic parameters are consistent with the novel drug design goals, and encouraging results warran...

Vitamin K Supplementation Modulates Bone Metabolism and Ultra-Structure of Ovariectomized Mice.

Osteoporosis is a bone metabolic disease that affects mostly post-menopausal women. There has been shown that vitamin K (VK) supplementation during menopause may decrease bone loss as well as risk of bone breaking. Aiming to clarify the beneficial role of VK in bone metabolism during menopause, we investigated mineral metabolism and bone ultrastructure of ovariectomized (OVX) mice.

Effects of Recombinant Human Growth Hormone in Children with Crohn's Disease on the Muscle-Bone Unit: A Preliminary Study.

There is limited information on the impact of recombinant human growth hormone (rhGH) on the muscle-bone unit in children with Crohn's disease (CD). In this pilot study, we report on the effects of rhGH on bone formation, dual-energy X-ray absorptiometry (DXA) total body (TB) bone mineral density adjusted for height and lumbar spine (LS) bone mineral apparent density (BMAD), and body composition.

Glucocorticoids and bone: consequences of endogenous and exogenous excess and replacement therapy.

Osteoporosis associated with long-term glucocorticoid therapy remains a common and serious bone disease. In addition, in recent years it has become clear that more subtle states of endogenous glucocorticoid excess may have a major impact on bone health. Adverse effects can be seen with mild systemic glucocorticoid excess but there is also evidence of tissue-specific regulation of glucocorticoid action within bone as a mechanism of disease. This review article will examine a) the role of endogenous glucocort...

Acetylcholinesterase activity and bone biochemical markers in premature and full-term neonates.

Background Almost 30% of the premature infants have low body weight and bone mineral density due to prematurity. There is no consensus of screening premature neonates for metabolic bone disease; therefore, it is important to investigate the use of bone biochemical parameters. Latest studies involved the activity of acetylcholinesterase as a mediator in bone remodeling. It is hypothesized that there is a possible correlation of bone biochemical biomarkers and acetylcholinesterase (AChE) activity in premature...

Huge Abdominal Photopenic Area Due to Kidney Cyst Imaged by Bone Scintigraphy in a Prostate Cancer Patient.

Bone scintigraphy is a method of choice in evaluating metastatic disease in patients with prostatic cancer. We describe the case of a 77-year-old man who was subjected to bone scan for evaluation of secondary metastatic disease due to an elevated prostatic-specific antigen level (7.2). Bone scintigraphy demonstrated a huge photopenic area in the left upper abdominal area, as a result of a huge kidney cyst (15 × 13 cm).

Bone mineral density, lung function, vitamin D and body composition in children and adolescents with cystic fibrosis: a multicenter study.

cystic fibrosis (CF) is the most common inherited disease in Caucasian population. Nowadays, long survival has led to the emergence of new complications, such as CF bone disease (CFBD), which is characterized by increased fracture risk.

Bone Involvement in Hodgkin's Lymphoma: Clinical Features and Outcome.

Hodgkin's lymphoma (HL) is now a highly curable disease, with an improving 5-year survival rate that has now reached 86%. At the time of presentation, HL is usually almost entirely confined to the lymph nodes. We performed a retrospective single-institution study of 384 cases with a median follow-up of 44 months, with the aim of identifying clinical and radiological characteristics and outcomes of patients with bone HL; 32 patients (8%) had primary bone involvement, always with concurrent nodal disease. The...
