Abstract Type I diabetes mellitus (T1DM) patients are at risk of osteoporosis and fracture due to the osteoblast and osteoclast malfunction. Osteopontin (OPN) as the major non-collagenous bone matrix protein is produced by osteoblasts and osteoclasts and involve in bone resorption, formation and remodeling. To evaluate the serum levels of OPN, bone mineral density (BMD) and correlation in patients with T1DM this study was designed. In this case-control study, 87 children with T1DM and 87 age/sex-matched healthy subjects were enrolled. Blood samples were tested for OPN levels by ELISA. Dual energy X-ray absorptiometry was used to measure BMD. The mean levels of BMD in patients was significantly lower than control group (p<0.0001). There was no significant difference between patients and healthy subjects regarding the levels of OPN. However, in patients with high levels of OPN (mean+1.5 standard deviation) the BMD was significantly lower than other patients (p<0.0001). Totally there was a negative correlation between serum levels of OPN and BMD in patients with T1DM (p<0.016). These results indicated that the BMD in T1DM is less than healthy children and elevated level of OPN in patients could be associated with low BMD. A linear negative correlation between serum OPN and total BMD of T1DM patients compared to control group was noticed in this study indicating that the amount of serum OPN could be effective on BMD and a good predicting factor for osteoporosis in patients.

Objective.To evaluate the effect of anti-tumor necrosis factor (TNF) therapy on bone mineral density (BMD) in patients with active ankylosing spondylitis (AS) with low BMD.Methods.Eighty-nine patients with active AS with low BMD were randomly divided into either a study group or a control group. The study group received etanercept (50 mg/week) or adalimumab (40 mg/2 week) subcutaneously for 1 year. BMD of lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry, and bone turnover markers serum C telopeptide of type-I collagen (sCTX) and serum procollagen type-I N propeptide (PINP) were detected by ELISA at baseline and at end of study.Results.After 1 year, compared with baseline, there was a significant increase in spine and femoral neck BMD by a mean ± SD of 14.9% ± 15.6% (p < 0.0001) and 4.7% ± 7.9% (p < 0.0001) in the study group. In the control group, there was a significant decrease in spine and femoral neck BMD by a mean ± SD of −8.6% ± 9.7% (p < 0.0001) and −9.8% ± 11.5% (p < 0.0001). Compared with baseline, sCTX was significantly decreased in the study group (−40% at 1 yr, p < 0.0001), but bone-specific alkaline phosphatase and PINP increased (45.6%, p < 0.0001 and 30.8%, p < 0.0001, respectively).Conclusion.In patients with active AS with low BMD, the spine and femoral neck BMD increased after anti-TNF therapy for 1 year, and it was accompanied by a significant decrease in bone resorption markers and an increase in bone formation markers.

Background: The present study examined the effect of intermittent fasting (IF) on bone mineral content (BMC) and bone mineral density (BMD) and the markers of bone remodeling in a glucocorticoid-induced osteoporosis (GIO) rat model.Methods: Forty male rats were allocated to 4 groups (N=10 per group): control group of normal rats; control+IF group (normal rats subjected to IF for 16-18 hr daily for 90 days); dexamethasone (DEX) group: (DEX [0.5 mg i.p.] for 90 days); and DEX+IF group (DEX and IF for 90 days). By the end of the experiment, BMD and BMC in the right tibia were measured. Serum levels of the following were measured: glucose; insulin; triglycerides (TGs); total cholesterol; parathyroid hormone (PTH); osteoprotegerin (OPG); receptor activator of nuclear factor-κB (RANK); bone-resorbing cytokines, including bone deoxypyridinoline (DPD), N-terminal telopeptide of collagen type I (NTX-1), and tartrate-resistant acid phosphatase 5b (TRAP-5b); and bone-forming cytokines, including alkaline phosphatase (ALP) and osteocalcin (OC).Results: DEX administration for 90 days resulted in significantly increased serum levels of glucose, insulin, TGs, cholesterol, PTH, OPG, DPD, NTX-1, and TRAP-5b and significantly decreased BMD, BMC, and serum levels of RANK, OC, and ALP (all P<0.05). IF for 90 days significantly improved all these parameters (all P<0.05).Conclusions: IF corrected GIO in rats by inhibiting osteoclastogenesis and PTH secretion and stimulating osteoblast activity.

Background and Objective. Variation of osteoporosis in the population is the result of an interaction between the genotype and the environment, and the genetic causes of osteoporosis are being widely investigated. The aim of this study was to analyze the association between the polymorphisms of the vitamin D receptor (VDR), type I collagen (COL1A1), and lactase (LCT) genes and severe postmenopausal osteoporosis as well as bone mineral density (BMD). Material and Methods. A total of 54 women with severe postmenopausal osteoporosis and 77 controls (mean age, 58.3 years [SD, 6.2] and 56.7 years [SD, 7.42], respectively) were included into the study. The subjects were recruited at the City Center for Osteoporosis Prevention (Minsk, Belarus). Dual-energy x-ray absorptiometry was used to measure bone mineral density at the lumbar spine and the femoral neck. Severe osteoporosis was diagnosed in the women with the clinical diagnosis of postmenopausal osteoporosis and at least 1 fragility fracture. The control group included women without osteoporosis. Polymorphic sites in osteoporosis predisposition genes (ApaI, BsmI, TaqI, and Cdx2 of the VDR gene, G2046T of the COL1A1 gene, and T-13910C of the LCT gene) were determined using the polymerase chain reaction on the deoxyribonucleic acid isolated from dried bloodspots. Results. The data showed that the ApaI and BsmI polymorphisms of the VDR gene and T- 13910C of the LCT gene were associated with severe postmenopausal osteoporosis in the analyzed Belarusian women (P<0.01). A statistically significant positive correlation between the VDR risk genotypes ApaI and TaqI and bone mineral density was found (P<0.05). Conclusions. The findings of this study suggest that at least the ApaI and BsmI polymorphisms of the VDR gene and T-13910C of the LCT gene are associated with the risk of postmenopausal osteoporosis in our sample of the Belarusian women.

Background: This prospective study was performed to compare calcaneal and lumbar bone mineral density (BMD) in individuals with and without diabetes mellitus. We compared bone density with the time from onset of Charcot’s neuroarthropathy (CN) in patients with unilateral, nonoperative, reconstructive-stage CN. The final purpose was to investigate the role that sex, age, and serum vitamin D level may have in osseous recovery. Methods: Thirty-three individuals were divided into three groups: controls and patients with diabetes mellitus with and without CN. Peripheral instantaneous x-ray imaging and dual-energy x-ray absorptiometry were performed. Results: The calcaneal BMD of patients with diabetes mellitus and CN was lower than that of the control group (P &lt; .01) but was not significantly lower than that of patients with diabetes mellitus alone. There was no statistically significant difference in lumbar T-scores between groups. Women demonstrated lower BMD than did men (P = .02), but patients 60 years and older did not demonstrate significantly lower BMD than did patients younger than 60 years (P = .135). A negative linear relationship was demonstrated between time and BMD in patients with CN. Conclusions: The results of this study suggest that lumbar BMD does not reflect peripheral BMD in patients with diabetes mellitus and reconstructive-stage CN. This study has clinical implications when reconstructive osseous surgery is planned in patients with CN. (J Am Podiatr Med Assoc 102(3): 213–222, 2012)

AbstractObjectivesReduced levels of α-Klotho is associated with the pathogenesis of various diseases including diabetes. In type I diabetes, decrease in Klotho leads to apoptosis of β-cells of pancreases. The aim of this study was to evaluate the levels of α-Klotho in type I diabetic pediatric patients.MethodsIn this cross-sectional single centered study, 46 patients presenting type I diabetes mellitus (case group) and 78 control group under the age of 12, referred to our clinic were included in our study. Serum levels of soluble Klotho were measured by sandwich ELISA in case and control groups. Statistical analysis was conducted for the data recorded via questionnaire.ResultsMean age of the patients in the case and control group was 7.65 ± 3.09 and 7 ± 2.37, respectively. Type I diabetes patients had a significant reduction in the levels of serum Klotho, as compared to controls (p<0.001). However, gender and age-based comparison between patient and control group was not significant.ConclusionsThis study reports a significant decrease in the serum levels of α-Klotho in type 1 diabetic patients. Low levels of Klotho can be associated with diabetic nephropathy and other comorbidities in these patients.

The aim of the study was to evaluate foot bone mineral density (BMD) in diabetes mellitus (DM) complicated with distal neuropathy (DN). Materials and methods. 61 patients with DM (DM1-27, DM2-34) were included. 37patients had Charcot osteoarthropathy (the 1st group), the 2nd group (13 patients) with severe DN, the 3rd group (11 patients) with mild DN, and control group consisted of 15 healthy people. All patients underwent dual energy X-ray absorptiometry (DXA) Lunar Prodigy scan. BMD was measured in lumbar spine, hip and radius. Foot BMD was measured using the «Total Body» region’s analysis. Results. There was a significant difference in foot BMD between controls and the 1st (р=0,031) and the 3rd (р=0,027) groups with no significant difference between the groups of patients. Foot BMD significantly correlated with spine, hip and radiusBMD (г=0,5-0,63, р<0,00001), BMI (r=0,4, р=0,000). Negative correlation was found between foot BMD and diabetes duration (r=-0,3, p<0,005) and HbA1c (r=-0,2, р=0,045). No correlation was found between DN and foot BMD. Conclusion. No association between severity of DN and foot BMD was found.

Introduction: Reduction in bone mineral density (BMD) is a common side effect of androgen deprivation therapy (ADT). We aimed to examine the cross-sectional and longitudinal variation in BMD and associated bone markers in patients with nonmetastatic prostate cancer (PCa) managed with and without ADT. Methods: Bone mineral density of the total body, lumbar spine, femoral neck, ultradistal forearm, and one-third distal radius was measured in 88 patients with PCa without bone metastases at baseline and at 6 months. Patients were categorized into 4 groups: (1) acute ADT (≤6 months), (2) chronic ADT (>6 months), (3) former ADT, and (4) no ADT (controls). Serum levels of bone metabolism markers, procollagen type I N-terminal propeptide (PINP) and C-terminal cross-linking telopeptide of type I collagen (CTX), were also measured. Results: In the cross-sectional analysis, men receiving chronic ADT had significantly lower total body BMD as compared with former ADT users and men with no ADT. In longitudinal analysis, a significant reduction in ultradistal forearm BMD was observed in both acute and chronic ADT users after 6 months (4.08% and 2.7%, P = .012 and .026, respectively). A significant reduction in total body BMD was observed in acute ADT users (2.99%, P = .032). Former ADT users had a significant increase in both lumbar spine and femoral neck BMD (2.84% and 1.59%, P = .008 and .002, respectively). The changes in BMD were not significantly different between acute and chronic ADT users. In the cross-sectional analysis, higher levels of PINP and CTX were observed in acute and chronic ADT users than former ADT users or PCa controls. In longitudinal analysis, the level of serum PINP and CTX did not change significantly from baseline to 6 months in acute, chronic, and former ADT users, or PCa controls, and the percentage change did not differ among the 4 groups. Conclusions: Men on acute ADT had a similar rate of bone loss to men on chronic ADT. Reversibility in ADT-induced bone loss was observed in those who discontinued ADT. Serum levels of PINP and CTX were higher in acute and chronic ADT users and levels returned to the range of PCa controls when treatment was withdrawn.

The effect of chronic intermittent hypobaric hypoxia (CIHH) on bone fracture healing is not elucidated. The present study aimed to investigate the role of CIHH on bone fracture healing and the mechanism. The Sprague-Dawley rats were randomly divided into the CIHH group and control group and monitored for 2, 4, or 8 weeks after femoral fracture surgery. Bone healing efficiency was significantly increased in the CIHH group as evidenced by higher high-density bone volume fractions, higher bone mineral density, higher maximum force, and higher stiffness. Histologically, the CIHH group exhibited superior bone formation, endochondral ossification, and angiogenic ability compared with the control group. The expression of HIF-1α and its downstream signaling proteins VEGF, SDF-1/CXCR4 axis were increased by the CIHH treatment. Moreover, the expression of RUNX2, osterix, and type I collagen in the callus tissues were also up-regulated in the CIHH group. In conclusion, our study demonstrated that CIHH treatment improves fracture healing, increases bone mineral density, and increases bone strength via the activation of HIF-1α and bone production-related genes.

Objectives: The present study examined the effect DHEA (dehydroepiandrosterone) on bone mineral content (BMC) and bone mineral density (BMD) and biomarkers of bone remodeling in orchidectomized male rats. Material and Methods: A total of 32 male rats were divided equally into four groups (n = 8): (i) control group (C), (ii) control treated with DHEA (Control + DHEA), (iii) orchidectomized (ORCH) group that underwent bilateral orchidectomy and (iv) orchidectomized (ORCH) rats treated with DHEA (ORCH+DHEA). DHEA treatment started 4 weeks after orchidectomy and continued for 12 weeks. After 12 weeks the bone mineral density (BMD) and bone mineral content (BMC) were assayed in the tibia and femur of the right hind limb of each rat. We also measured the serum levels of the bone turnover markers deoxypyridinoline (Dpd), N-telopeptide of type I collagen (NTx), alkaline phosphatase (ALP), tartrate-resistant acid phosphatase 5b (TRAP-5b) and osteocalcin (OC) as well as receptor activator of nuclear factor kappa B (RANK) and osteoprotegerin (OPG). Results: Orchidectomy in rats caused significant reduction in BMD, BMC, serum levels of testosterone, PTH (parathyroid hormone), OPG, OC and ALP with significant rise in serum levels of TRAP-5B, RANK, Dpd and NTx1 (p < 0.05). On the other hand, DHEA therapy for 12 weeks caused significant improvement in all studied parameters except NTx1 (p < 0.05). Conclusions: DHEA corrected hypogonadism-induced osteoporosis in male rats probably via inhibiting osteoclastogenesis, stimulating the activity of osteoblasts and stimulating the secretion of PTH and testosterone.
