Dickkopf 1

ObjectiveDickkopf-1 (DKK-1) is an inhibitor of osteoblastogenesis, and its lower levels are linked to new bone formation. The aim of this study was therefore to explore serum levels of DKK-1 and to evaluate DKK-1's association with the severity of spinal involvement in diffuse idiopathic skeletal hyperostosis (DISH).MethodsSerum levels of total and functional DKK-1 and C-reactive protein (CRP) were measured in 37 patients with DISH and 22 healthy age and sex-matched controls. Plain radiographs of the cervical and thoracic spine were performed, and the diagnosis of DISH was defined using the Resnick criteria. Patients were divided into three groups based on spinal involvement. Bone mineral density (BMD) and bone turnover markers were evaluated in patients with DISH.ResultsThe levels of total serum DKK-1 were significantly lower in patients with DISH than in healthy controls (p<0.0001). Importantly, low serum levels of DKK-1 were associated with more severe spinal involvement in DISH, independent of age, sex, disease duration, CRP, bone turnover markers or BMD. However, these findings were less significant for functional DKK-1.ConclusionThese observations indicate that DKK-1 may play a significant role in bone formation during DISH.

Abstract Purpose/introduction To compare serum levels of bone turnover markers in athletes and non-athletes, and to evaluate the relationship between serum levels of vitamin D metabolites and exercise-induced changes in biomarker levels. Methods Sixteen elite male artistic gymnasts (EG; 21.4 ± 0.8 years-old) and 16 physically active men (the control group, PAM; 20.9 ± 1.2 years-old) performed lower and upper body 30-s Wingate anaerobic tests (LBWT and UBWT, respectively). For biomarker analysis, blood samples were collected before, and 5 and 30 min after exercise. Samples for vitamin D levels were collected before exercise. N-terminal propeptide of type I collagen (PINP) was analysed as a marker of bone formation. C-terminal telopeptide of type I collagen (CTX) was analysed as a marker of bone resorption. Results UBWT fitness readings were better in the EG group than in the PAM group, with no difference in LBWT readings between the groups. UBWT mean power was 8.8% higher in subjects with 25(OH)D3 levels over 22.50 ng/ml and in those with 24,25(OH)2D3 levels over 1.27 ng/ml. Serum CTX levels increased after both tests in the PAM group, with no change in the EG group. PINP levels did not change in either group; however, in PAM subjects with 25(OH)D3 levels above the median, they were higher than those in EG subjects. Conclusion Vitamin D metabolites affect the anaerobic performance and bone turnover markers at rest and after exercise. Further, adaptation to physical activity modulates the effect of anaerobic exercise on bone metabolism markers.

Abstract Objective The threefold aim was to (1) compare areal bone mineral density (aBMD), bone turnover markers, and periostin levels in young women with either anorexia nervosa (AN) or obesity (OB) and controls (CON); (2) model the profiles according to age; and (3) determine the parameters associated with aBMD. Subjects and Methods One hundred and fifty-two young women with ages ranging from 16.0 to 27.0 years were subdivided into 3 groups (AN, OB, CON). The CON group was age-matched by ±6 months. aBMD, bone turnover markers, and periostin levels were evaluated. Results aBMD modeling showed that hip aBMD was higher in OB than in the other 2 groups from 19 years, and AN presented lower values than CON from 21 years. aBMD at the lumbar spine was higher in older OB and CON women, starting from 20 to 22 years, but in AN the difference with the other 2 groups increased with age. Periostin levels were lower in OB than in AN or CON, but no variation with age was observed. Compared with controls, OB and AN presented similarly lower markers of bone formation, although markers of bone resorption were lower in OB and higher in AN. A modeling approach showed that markers of bone formation and resorption were lower in older than in younger CON, whereas the values of these bone markers remained relatively constant in AN and OB. In all groups, lean body mass (LBM) was the parameter most positively correlated with aBMD. Conclusion This study demonstrated that weight extremes (AN or OB) influence aBMD, bone remodeling and periostin profiles. Moreover, factors related to aBMD were specific to each condition, but LBM was the parameter most consistently associated with aBMD.

Markers Of Bone Formation

Bone is a living tissue, metabolically very active, with the level of turnover of about 10% per year. Bone remodeling is a well-balanced process of bone resorption, induced by osteoclasts and bone formation maintained osteoblasts. Loss of bone remodeling balance, with increased bone resorption, leads to osteoporosis. Bone turnover markers are classified as markers of bone formation and of bone resorption. During the growth and development of skeleton, bone turnover markers show higher levels of activity than in the adult period. The increase in biochemical markers peaks again in the postmenopausal period, indicating accelerated bone remodeling. Bone mineral density is an important predictor of an osteoporotic fracture. Timely assessment of risk factors of osteoporosis and bone markers can detect subjects with accelerated bone remodeling and osteoporosis. This may introduce adequate therapy and prevent fracture.

OBJECTIVE: To review and summarize studies on the effects of romosozumab as sequential therapy for improvements in bone turnover markers, bone mineral density (BMD), and clinical fracture in postmenopausal (PMP) women.<br/> DATA SOURCES: A search of PubMed (1966-August 2019) and International Pharmaceutical Abstracts (1970-August 2019) was conducted using the MeSH and key word term romosozumab and limited to controlled clinical trials.<br/> STUDY SELECTION AND DATA EXTRACTION: An initial review yielded 12 articles. Articles that did not evaluate use of romosozumab before or after another osteoporosis treatment were excluded. Five articles that evaluated the effects of sequential treatment with romosozumab in PMP women on bone turnover markers, bone mineral density, and fracture were included in the final review.<br/> DATA SYNTHESIS: Romosozumab is a humanized, monoclonal antibody that increases bone formation and reduces bone resorption via inhibition of sclerostin. This inhibition stimulates signaling pathways resulting in increased bone formation, reduced bone resorption and increases in BMD. Romosozumab is indicated for the treatment of osteoporosis in PMP women who are at high risk for fracture and failed or cannot take other treatments. The current evidence describing the controlled clinical trials that evaluated use of romosozumab in sequence with other therapies for treatment of PMP osteoporosis is summarized.<br/> CONCLUSION: An evaluation of studies where romosozumab was used in sequence to other therapies in PMP women showed that it causes significant reductions in bone resorption markers, increases in bone-formation markers, improves BMD, and reduces the risk of clinical fracture. However, these efficacy improvements must be carefully weighed against the increased risk of cardiovascular adverse effects compared with other treatments.

AbstractBackgroundIn the aging individuals, osteoporosis is a major health problem. Due to the various limitations of dual X-ray absorptiometry (DEXA) for diagnosis osteoporosis, serum-based biochemical markers have been suggested for the discrimination between the patients and healthy subjects.ObjectiveTo investigate the serum levels of bone turnover markers in elderly osteoporosis patients.MethodsThe serum samples from elderly subjects (osteoporosis (n = 28), osteopenia (n = 28), and healthy ones (n = 28) were collected from Amirkola Health and Ageing Project study. Furthermore, serum levels of bone formation and bone resorption markers as well as estrogen and progesterone were measured by enzyme-linked immunosorbent assay. Kruskal–Wallis test and receiver operating characteristic curve analysis were used for statistical analysis using SPSS.ResultsLevels of bone alkaline phosphatase (B-ALP) and procollagen type I N-terminal propeptide (PINP) differed between groups (P = 0.003 and 0.009, respectively). Furthermore, PINP and B-ALP levels had the best area under the curve, sensitivity, and specificity for the discrimination between patients with osteoporosis and healthy individuals.ConclusionIn conditions in which we are not able to assess the bone mineral density by DEXA, analysis of the B-ALP and PINP levels may be a helpful tool.

Objective: To study the effects of square dance on bone mineral density (BMD) and bone turnover markers in patients with postmenopausal osteoporosis. Methods: Fifty postmenopausal women (aging 45–60) with osteoporosis were randomly assigned to a research group and a control group. The patients in the research group received 600[Formula: see text]mg of calcium combined with square dance (5 times a week, 30 to 60 minutes each time) for 6 months while those in the control group only received 600[Formula: see text]mg of calcium. BMD, changes in bone turnover markers and bone pain were assessed before and after the treatment. Results: (1) After the 6-month treatment, BMD of L[Formula: see text] and the femoral neck significantly increased in the research group ([Formula: see text]). No significant change was observed in BMD of the Ward’s region. BMD in the control group did not change significantly ([Formula: see text]). (2) No significant difference was found in serum levels of calcium, phosphorus and alkaline phosphatase between the two groups both before and after the treatment ([Formula: see text]). Serum levels of P1NP had a significant increase, while [Formula: see text]-CTX’s level did not change significantly. (3) The bone pain in both groups has been effectively relieved. The pain in the research group was relieved significantly compared to the control group. Conclusions: By improving the BMD and relieving the pain, square dancing can exert positive effects on women with postmenopausal osteoporosis. Square dancing may become a feasible strategy for osteoporosis prevention and treatment.

Turnover Markers

In men aged less than 60, the association of serum and urinary levels of biochemical bone turnover markers (BTMs) and bone mineral density (BMD) is weak or not significant. After this age, higher BTM levels are correlated weakly, but significantly, with lower BMD and faster bone loss. Limited data from the cohort studies suggest that BTM measurement does not improve the prediction of fragility fractures in older men in comparison with age, BMD, history of falls and fragility fractures. Testosterone replacement therapy (TRT) decreases bone resorption. During TRT, bone formation markers slightly increase (direct effect on osteoblasts), then decrease (slowdown of bone turnover). Bisphosphonates (alendronate, risedronate, ibandronate, zoledronate) induce a rapid decrease in bone resorption followed by a milder decrease in bone formation. In men receiving antiresorptive therapy for prostate cancer, zoledronate, denosumab and toremifene decrease significantly levels of bone resorption and bone formation markers. Teriparatide induced a rapid increase in serum concentrations of bone formation markers followed by an increase in bone resorption. We need more studies on the utility of BTM measurement for the improvement of the persistence and adherence to the anti-osteoporotic treatment in men.
