Abstract Introduction: It has been shown that dyslipidemia is related to bone mineral density and fragility. Hypolipemiant drugs as statins or fibrates seem to increase the bone mineral density and probably to protect against fractures. The question that arises in this context is whether statins or fibrates have a positive effect on bone fracture repair process and which is their behaviour in an osteoporotic context. Our objective was to study the incidence of osteoporosis, dyslipidemia and of the association of these diseases, and to compare the effect of statins and fibrates on fracture repair in experimental conditions. Material and method: We studied the incidence of dyslipidemia and osteoporosis in the activity of a private family medicine cabinet. In the experimental part we observed from a radiographic point of view the fracture repair process of rats’ femurs. We analyzed 6 subgroups of 12 rats each: (1) ovariectomized control, (2) ovariectomized treated with statins, (3) ovariectomized treated with fibrates, (4) nonovariectomized control, (5) ) nonovariectomized treated with statins, (6) ) nonovariectomized treated with fibrates. The radiographic aspect has been objectified with a score at 2, 4, 6 and 8 weeks. Results: From the total of 646 patients included in the study, 193 (29.87%) had dyslipidemia while osteoporosis was diagnosed at 152 (23.53%) patients. 301 (46.6%) patients presented the association of these diseases. Comparing the subgroups of the OVX group, we had the following results: subgroup 1 - 5.5 points, group 2 - 11 points and group 3 - 4.5 points. In the case of the NOVX subgroups, the scores were: subgroup 4 - 7.5 points, subgroup 5 - 10 points and subgroup 6 - 6.5 points. Conclusions: The fact that the incidence of dyslipidemia is higher than that of osteoporosis is an argument for the necessity of choosing a hypolipemiant treatment that has, at the same time, a protective effect on bone. Hypolipemiant treatment influences the fracture repair process. The positive effect of statins on this process is more important on the ovariectomized group, in contrast with fibrates which have an accentuated effect on the nonovariectomized group and this suggests an interference between hypolipemiant treatment and estrogens level. However, the treatment with fibrates delays the fracture repair, groups (3) and (6) scores being inferior to those of the control group. We sustain the helping effect of statins treatment on fracture repair process.

Background/Aim. It is well known that physical activity has an anabolic effect on bone tissue. But there is a lack of information about the effect of intensive physical activity in childhood, particularly at the prepubertal stage. To examine the influence of training on body composition and bone mineral density we have studied a group of prepubertal soccer players as well as a group of inactive prepubertal boys at the starting phase of their peak bone mass acquisition. Methods. A total of 62 healthy prepubertal boys took part in this study. They were divided into two groups. The first one consisted of 32 soccer players (aged 10.7 ? 0.5 years), who had been playing football for at least 1 year (10-15 h per week). The second group a control group 30 boys (aged 11.2 ? 0.7 years) doing 1.5 h per week physical activity at school. Body composition was assessed by a Body Fat Analyzer 'BES 200 Z'. Bone mineral density measurements of the left and the right calcaneus were done by using ultrasound densitometer 'Sahara' (Hologic, Inc., MA, USA). Results. There were significant differences between soccer players and the control group in fat mass (p = 0.01). Besides, a significant difference was determined between the group of athletes and the control group in bone mineral density of both calcaneal bones (p = 0.01). Conclusion. The results of this study confirm the significant effects of physical activity on reducing body mass and increasing bone density. Considering that football training can be very easily implemented in the broader population of children and young people, which does not apply to many other sports, it should be used more in the prevention of obesity and osteoporosis.

The aim of this study was to evaluate the effect of denosumab (Dmab) on bone mineral density (BMD) and bone turnover markers after 1 year of treatment. Additionally, the effect of Dmab in bisphosphonate-naïve patients (BP-naïve) compared to patients previously treated with bisphosphonates (BP-prior) was analyzed. This retrospective study included 425 postmenopausal women treated with Dmab for 1 year in clinical practice conditions in specialized centers from Argentina. Participants were also divided according to previous bisphosphonate treatment into BP-naïve and BP-prior. A control group of patients treated with BP not switched to Dmab matched by sex, age, and body mass index was used. Data are expressed as mean ± SEM. After 1 year of treatment with Dmab the bone formation markers total alkaline phosphatase and osteocalcin were significantly decreased (23.36% and 43.97%, resp.), as was the bone resorption marker s-CTX (69.61%). Significant increases in BMD were observed at the lumbar spine, femoral neck, and total hip without differences between BP-naïve and BP-prior. A better BMD response was found in BP-prior group compared with BP treated patients not switched to Dmab.Conclusion. Dmab treatment increased BMD and decreased bone turnover markers in the whole group, with similar response in BP-naïve and BP-prior patients. A better BMD response in BP-prior patients versus BP treated patients not switched to Dmab was observed.

Introduction. Vitamin D active metabolites deficit that is altered by negative calcium and phosphorus balance is a potential complication during long?term antiepileptic drug therapy. Objective. The aim of this study was to examine lumbar bone mineral density (BMD) in epileptic children receiving antiepileptic drug therapy longer than one year. methods. The examined sample consisted of 34 epileptic children, 18 male and 16 female, aged 6?12 (9.77?2.01) years, treated with carbamazepine, valproate, phenobarbital, lamotrigine or their combination without vitamin D supplementation. The lumbar spine BMD (L1?L4) was estimated by a Lunar densitometer and obtained results were compared with results of 35 matched population of healthy children from the control group. results. Lumbar BMD Z?score was significantly lower in female patients treated with antiepileptic therapy compared with those in the control group (?1.048?1.35 vs. ?0.399?0.518; p=0.03). Bone mineral density Z?score decrease of both gender groups receiving antiepileptic polytherapy was significantly lower compared to the control group (?1.153?0.938 vs. ?0.043?0.815; p=0.007). Therapy duration had no influence on the lumbar BMD level decrease either in boys (rxy=0.33; p=0.174) or in girls (rxy=0.02; p=0.935) treated with antiepileptic therapy. Conclusion. Our results have indicated that antiepileptic drug therapy usage longer than one year can have adverse affects on the lumbar spine BMD (L1?L4) in epileptic children, and that prophylactic vitamin D supplementation is also necessary in these patients.

Objective: To verify the effect of recreational soccer on bone mineral density and sarcopenia in the elderly. Methods: Fourteen elderly people aged 65.9 ± 3.4 years were selected. They were separated into two groups: the intervention group and the control group; the intervention group played recreational soccer for 12 weeks on two days of the week. Assessments were performed for bone mineral density and body muscle mass before and after the intervention. For statistical analysis, the repeated measures ANOVA with Bonferroni’s post hoc test was used. Results: After 12 weeks, there was a significant change in bone mineral density in the region of the total femur (p = 0.020). Analyzing the participants’ sarcopenia, no significant results were found after the intervention period. Conclusion: Playing recreational soccer causes a significant improvement in the total femur and maintains bone regions in the spine, whole body, and femoral neck. Also, it promotes a removal from the threshold for sarcopenia screening in the elderly.

Abstract Background: Bone mineral density (BMD) of the proximal femur around the stem decreases due to stress shielding after cementless total hip arthroplasty (THA). When severe stress shielding occurs, the risk of periprosthetic femoral fractures increases, and this bone loss can also increase the difficulty of future revision THA. Denosumab is known to improve the quality and strength of cortical bone in the proximal femurs of patients with osteoporosis. The purpose of this study was to investigate whether denosumab prevents loss of proximal femoral periprosthetic BMD in cementless THA using a tapered wedge stem in patients with osteoporosis.Methods: Sixty-three consecutive patients who had undergone unilateral primary THA using a tapered wedge stem were included in this retrospective study. Twenty-four patients who received denosumab for osteoporosis were the denosumab group, and the 39 without denosumab were the control group. At 2 weeks, 6 months, and 12 months after THA, bone turnover markers and femoral periprosthetic BMD were measured.Results: BMD in zone 1 was significantly increased from baseline at both 6 and 12 months after THA in the denosumab group and significantly decreased in the control group. BMD in zone 7 was significantly decreased compared to baseline at both 6 and 12 months after THA in the control group, but not in the denosumab group. The use of denosumab for THA patients with osteoporosis was independently related to preventing loss of periprosthetic BMD of the femur at 12 months after surgery in zones 1 and 7 on multivariate analysis.Conclusions: Denosumab significantly increased proximal femoral periprosthetic BMD in zone 1 and prevented loss of BMD in zone 7 in patients with osteoporosis after cementless THA using a tapered wedge stem at both 6 and 12 months after surgery.

Although it is well established that there is considerable inter-individual variation in the circulating levels of IGF-I in normal, healthy individuals and that a genetic component contributes substantially to this variation, the direct evidence that inter-individual variation in IGF-I contributes to differences in peak bone mineral density (BMD) is lacking. To examine if differences in IGF-I expression could contribute to peak BMD differences, we measured skeletal changes at days 23 (prepubertal), 31 (pubertal) and 56 (postpubertal) in mice with haploinsufficiency of IGF-I (+/−) and corresponding control mice (+/+). Mice (MF1/DBA) heterozygous for the IGF-I knockout allele were bred to generate +/+ and +/− mice (n=18–20 per group). Serum IGF-I was decreased by 23% (P<0.001) in mice with IGF-I haploinsufficiency (+/−) group at day 56 compared with the control (+/+) group. Femoral bone mineral content and BMD, as determined by dual energy X-ray absorptiometry, were reduced by 20% (P<0.001) and 12% respectively in the IGF-I (+/−) group at day 56 compared with the control group. The peripheral quantitative computed tomography measurements at the femoral mid-diaphysis revealed that periosteal circumference (7%, P<0.01) and total volumetric BMD (5%, P<0.05) were decreased significantly in the +/− group compared with the +/+ group. Furthermore, serum IGF-I showed significant positive correlations with both areal BMD (r=0.55) and periosteal circumference (r=0.66) in the pooled data from the +/+ and +/− groups. Our findings that haploinsufficiency of IGF-I caused significant reductions in serum IGF-I level, BMD and bone size, together with the previous findings, are consistent with the notion that genetic variations in IGF-I expression could, in part, contribute to inter-individual differences in peak BMD among a normal population.

Abstract Background: Osteoarthritis (OA) is the most common form of arthritis and characterized by degeneration of articular cartilage. Mitogen-inducible gene 6 (Mig-6) has been identified as a negative regulator of the Epidermal Growth Factor Receptor (EGFR). Cartilage-specific Mig-6 knockout (KO) mice display increased EGFR signaling, an anabolic buildup of articular cartilage and formation of chondro-osseous nodules. Since our understanding of the EGFR/Mig-6 network in cartilage remains incomplete, we characterized mice with cartilage-specific overexpression of Mig-6 in this study. Methods: Utilizing knee joints from cartilage-specific Mig-6 overexpressing (Mig-6over/over) mice (at multiple time points), we evaluated the articular cartilage using histology, immunohistochemical staining and semi-quantitative histopathological scoring (OARSI) at multiple ages. MicroCT analysis was employed to examine skeletal morphometry, body composition, and bone mineral density.Results: Our data show that cartilage-specific Mig-6 overexpression did not cause any major developmental abnormalities in articular cartilage, although Mig-6over/over mice have slightly shorter long bones compared to the control group. Moreover, there was no significant difference in bone mineral density and body composition in any of the groups. However, our results indicate that Mig-6over/over male mice show accelerated cartilage degeneration at 12 and 18 months of age. Immunohistochemistry for SOX9 demonstrated that the number of positively stained cells in Mig-6over/over mice was decreased relative to controls. Immunostaining for MMP13 appeared increased in areas of cartilage degeneration in Mig-6over/over mice. Moreover, staining for phospho-EGFR (Tyr-1173) and lubricin (PRG4) was decreased in the articular cartilage of Mig-6over/over mice. Conclusion: Overexpression of Mig-6 in articular cartilage causes no major developmental phenotype; however, these mice develop earlier OA during aging. These data demonstrate that Mig-6/EGFR pathways is critical for joint homeostasis and might present a promising therapeutic target for OA.

Abstract Background Anorexia nervosa (AN) is a serious eating disorder that is associated with decreased bone mineral density (BMD) and greater lifetime risk for fractures. The aim of this study was to determine the correlation between BMD and genetic polymorphisms in AN. Methods This case-control study analyzed vitamin D receptor (VDR) (VDRBsml, VDRFokl) and estrogen receptor (ESR) (ESR1Xbal, ESR1Pvull) polymorphisms in 45 adolescents diagnosed with AN and 46 age-matched healthy controls. BMD values of the AN group were classified as low or normal, and polymorphisms were compared between cases and controls. The effects of body mass index (BMI), duration of disease and amenorrhea on BMD were also evaluated. Results In girls with AN, a positive effect of the bb genotype of VDRBsmI polymorphism on femur Z-scores (p = 0.103) and of the Ff genotype of VDRFokI polymorphism on vertebra Z-scores (p = 0.097) was observed. In boys with AN, a positive effect of the Ff genotype of VDRFokI polymorphism on vertebra BMD (g/cm2) was detected (p = 0.061). No association was detected between ESR polymorphisms. An inverse relationship was observed between BMD and duration of illness and amenorrhea. A direct relationship was detected between BMD and BMI. Conclusions Specific VDR gene polymorphism genotypes may have positive effects on BMD in patients with AN. Additionally, the lack of association between ESR gene polymorphisms on BMD could be attributed to the low estrogen status of the patient.
