Background and Objectives: Rheumatoid arthritis (RA) is a chronic disease characterized by severe bone destruction which has been associated with altered lipid metabolism. Apolipoprotein E (Apo E) is a lipoprotein mainly produced by macrophages. ApoE has been described as crucial in lipid metabolism but also as an important anti-inflammatory mediator regulating innate immunity and bone turnover. In the present study we investigated the role of Apo E in bone destruction during ...

Osteoporosis is the commonest worldwide age-related bone disease. It is clinically symptomless until the first fracture happens. Circulating microRNAs can be used as novel biomarkers to assess health status and progression of complex diseases. A recent review highlighted the involvement of microRNAs in the control of bone formation and remodeling. Most of these studies have been done on animal models, but few on human blood samples.This research aims to ...

Background: Recently, we showed that treatment with COBRA-light therapy including prednisone with initially 30 mg/day was as effective as the original COBRA scheme, with initially 60 mg/day (Ter Wee, ARD 2015), in the treatment of rheumatoid arthritis (RA). Since high-dose glucocorticoids are associated with bone loss, we investigated the differences in bone mineral density (BMD) after 1 year of treatment in both arms.Objective: To determine whether ther...

Introduction: Cranialfacial fibrous dysplasia (CFD) presents with pain, facial asymmetry and/or neurological complications. It has been suggested that patients with CFD respond favourably to treatment with bisphosphonates, by a decrease in pain and arrest of progression. Therefore, we performed a retrospective study of 56 patients with CFD in our center.Methods: We assessed clinical characteristics and disease course. Furthermore, clinical and biochemica...

Background: The Ketogenic Diet Treatment (KDT) is a well-established intervention for intractable childhood epilepsy and the first choice treatment for Gluccose-1-transporter-deficiency-syndrome and Pyruvate-dehydrogenase-complex deficiency. During long-term follow up of children treated with KDT an increased incidence of bone fractures has been found. However, the exact contribution of KDT to a decreased BMD remains unclear. Prophylactic supplementation with calcium and vitam...

Objectives: We recently demonstrated that cow’s milk allergic infants who received an amino acid-based formula (AAF) for 16 weeks as oral feeding had adequate mineral status (1). One factor that may negatively affect mineral solubility and bioavailability and hence mineral status, is high gastric pH (2), but data on this in infants are lacking. Therefore, the present study evaluates serum concentrations of phosphorus, calcium and magnesium in a subgroup of infants on AAF ...

Objectives: Osteopenia is a complication of childhood cancer treatment but it is unknown to which extend this occurs in adult survivors, and which subgroups are at risk. We examined bone mineral density (BMD) and assed the relative importance of potential determinants of low BMD in very long-term adult survivors of childhood cancer.Methods: The single-center cohort study included 410 adult CCSs (median age at diagnosis: 6.6 years (range: 0–17 years)...

Objectives: Osteonecrosis (ON) and decline of bone mineral density (BMD) are serious side effects during and after treatment of childhood acute lymphoblastic leukemia (ALL). It is unknown whether ON and low BMD co-occur in the same patients, and whether these two osteogenic side-effects can mutually influence each other’s development.Methods: BMD and the incidence of symptomatic ON were prospectively assessed in a national cohort of 466 patients wit...

Prostate cancer is the most prevalent cancer in men and metastatic spread to bone is detected in up to 80% of patients with advanced disease at autopsy. PCa can progress from treatable androgen-dependent stage to castration-resistant stage with distant metastases for which novel therapeutic targets and strategies are urgently needed. Here we identify the cell surface/secreted oncoprotein Cripto as a potential target for the diagnosis and treatment of metastatic prostate cancer...

Objective: Increase the percentage of elderly fracture patients undergoing a dual energy X-ray absorptiometry (DXA) measurement, and investigate why some patients did not respond to invitation to our fracture liaison service (FLS).Materials and methods: In four Dutch hospitals, fracture patients ≥50 years were invited for a DXA measurement and visit to our FLS. Patients who did not respond, were contacted by telephone. In patients diagnosed with os...
