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 to therapy without hypervitaminosis D or hypercalcemia...

RATIONALE: Primary hyperparathyroidism (PHPT) during pregnancy is rare. Nevertheless, hypercalcemia secondary to gestational PHPT may be masked by physiological changes in calcium homeostasis during pregnancy. Gestational PHPT constitutes a serious danger to mother and fetus. Surgery is the only curative treatment when conservative treatment could not control the condition. Due to the lack of guidelines concerning PHPT during pregnancy, the optimal anesthetic management of PHPT during pregnancy needs to be individualized...

Myeloma bone disease (MBD) is the most common complication of multiple myeloma (MM), resulting in skeleton-related events (SREs) such as severe bone pain, pathologic fractures, vertebral collapse, hypercalcemia, and spinal cord compression that cause significant morbidity and mortality. It is due to an increased activity of osteoclasts coupled to the suppressed bone formation by osteoblasts. Novel molecules and pathways that are implicated in osteoclast activation and osteoblast inhibition have recently been described, including the receptor activator of nuclear factor-kB ligand/osteoprotegerin pathway, activin-A and the wingless-type signaling inhibitors, dickkopf-1 (DKK-1) and sclerostin...

Primary hyperparathyroidism (PHPT) has been increasingly diagnosed incidentally in its asymptomatic form owing to calcium screening tests. This form of PHPT represents 80% in developed countries. Although PHPT patients are asym-ptomatic, target organ (bone and kidney) involvement is frequently observed. Mild PHPT is associated with a reduction of bone mineral densityand, moreover, with increased risk of vertebral fractures. The extent of a patient evaluation and indications for parathyroidectomy are based on expert guidelines from 2014...

Bone metastases are common in patients with advanced solid tumors, and many individuals experience debilitating skeletal-related events (SREs; e.g. pathologic fracture, hypercalcemia, radiotherapy or surgery to bone, and spinal cord compression). These events substantially affect disease outcomes, including survival and quality of life, and healthcare systems. Plain radiography is the most widely used imaging modality for the detection of bone metastases; skeletal scintigraphy, computed tomography, positron emission tomography and magnetic resonance imaging offer greater sensitivity but their use in routine practice is restricted by high costs and limited availability...

Multiple myeloma (MM) is a malignancy of terminally differentiated B cells/plasma cells and is primarily located in the bone marrow. Symptomatic multiple myeloma typically presents with osteolyses, anemia, reduced renal function, and/or hypercalcemia. In the case of such MM-related end organ damage, urgent systemic treatment is indicated. In order to prevent end organ damage, current guidelines now recommend treatment initiation already when certain biomarkers are met. Current first-line treatment is based on proteasome inhibition and immunomodulation...

Introduction Due to the lack of formal guideline recommendations, available primary literature was used to develop a proposed protocol for management of hypercalcemia of malignancy at the University of Chicago Medical Center. Methods A retrospective, single center, observational study was performed including adult patients hospitalized with a diagnosis of hypercalcemia and active malignancy. Patients were retrospectively identified as treated in a manner aligned with the proposed protocol ("per protocol") or not treated according to the proposed protocol ("off protocol"), and the outcomes were compared...

Chronic kidney disease-mineral and bone disorder (CKD-MBD) encompasses laboratory and bone abnormalities and vascular calcification and has deleterious effects on clinical outcomes. KDOQI (Kidney Disease Outcomes Quality Initiative), an initiative of the National Kidney Foundation, addressed this issue with the publication of a clinical practice guideline for bone metabolism and disease in CKD in 2003, and 2 years later, a new definition and classification scheme for CKD-MBD was developed following a KDIGO (Kidney Disease: Improving Global Outcomes) Controversies Conference...

INTRODUCTION: Preterm neonates are particularly at risk of vitamin D (25-D) deficiency. To prevent rickets and osteopenia in this population, international guidelines vary between 800 and 1000IU per day of vitamin D in Europe and recommend 400IU per day in the USA. Target levels of circulating 25-D are not well identified, with the lower target level 50-75nmol/L and the upper target level probably 120nmol/L. METHODS: Between 2013 and 2015, 16 premature infants (born<35WG) were referred to pediatric nephrology clinics because of symptoms secondary to 25-D overdose during the neonatal period...

Extracellular calcium ([Ca2+ ]E ) concentration has been suggested to stimulate osteoblastic activity; thus, calcium can be used to enhance fracture healing. However, systemic administration of calcium at high dose levels may cause physiological problems such as hypercalcaemia. Short-span application of single or repetitive [Ca2+ ]E stimulus may be suggested as a novel regimen to reduce such side effects. However, osteopromotive effect of such short-term [Ca2+ ]E stimulus on osteoprogenitor cells has not yet been evaluated yet...

Maintenance of physiological levels of intracellular and extracellular calcium is essential for life. Increased intracellular calcium levels are involved in cell death (apoptosis and necrosis) and are associated with positive responses in the Comet assay in vitro. In addition, high calcium and vitamin D intakes were reported to induce apoptosis in adipose tissue in obese mice and to increase DNA-migration in the Comet assay. To investigate increased serum concentration of calcium as a potential confounding factor in the regulatory Comet assay in vivo, we induced mild hypercalcemia in male Wistar rats by 3-day continuous intravenous infusion of calcium gluconate and performed the Comet assay in the liver in line with regulatory guidelines...

BACKGROUND: Acute kidney injury (AKI) after liver transplantation (LT) is a frequent and serious complication. The incidence of AKI requiring continuous renal replacement therapy (CRRT) ranges from 10% to 30%. Kidney Disease: Improving Global Outcomes guidelines indicate the use of citrate as a locoregional anticoagulant drug for CRRT regardless of the patient's hemorrhagic risk. Despite this indication, however, the use of citrate is still under debate in patients with liver failure and/or LT owing to the potential risk of plasmatic citrate accumulation due to reduced liver clearance...

Research carried out during the past two-decades extended the understanding of actions of vitamin D, from regulating calcium and phosphate absorption and bone metabolism to many pleiotropic actions in organs and tissues in the body. Most observational and ecological studies report association of higher serum 25-hydroxyvitamin D [25(OH)D] concentrations with improved outcomes for several chronic, communicable and non-communicable diseases. Consequently, numerous agencies and scientific organizations have developed recommendations for vitamin D supplementation and guidance on optimal serum 25(OH)D concentrations...

Multiple myeloma (MM) is caused by the neoplastic proliferation of plasma cells. These neoplastic plasma cells proliferate and produce monoclonal immunoglobulin in the bone marrow causing skeletal damage, a hallmark of multiple myeloma. Other MM-related complications include hypercalcemia, renal insufficiency, anemia, and infections. The NCCN Multiple Myeloma Panel members have developed guidelines for the management of patients with various plasma cell dyscrasias, including solitary plasmacytoma, smoldering myeloma, multiple myeloma, systemic light chain amyloidosis, and Waldenström's macroglobulinemia...

Osteonecrosis of the jaw (ONJ) is a well known complication in patients treated with bisphosphonates (BPs) for skeletal metastasis and multiple myeloma (MM). Few oncologic patients under treatment with BPs and with ONJ and metastasis or MM at the same site of the jaw have been described. We report here on a 54-year old white female who was treated with intra-venous zoledronic acid for skeletal metastasis of breast cancer who developed ONJ. Because of a fracture at the site of ONJ, resection of the affected segment was performed...
