Abstract Background: The negative impact of anorexia nervosa (AN) on bone health is well defined. However, there are very few studies evaluating the effect of constitutional thinness on bone health, especially in the adolescent period and in the male gender. The aim of this study is to compare the bone mineral density (BMD) measurements of adolescents with AN and with constitutional thinness. Methods: Between April 2013 and March 2014, 40 adolescents with AN and 36 adolescents with constitutional thinness participated in the study. The femoral neck and lumbar spine BMD were measured by dual energy X-ray absorptiometry (DXA). Results: Mean lumbar z and BMD scores of adolescents with constitutional thinness were significantly lower than in adolescents with AN, whereas the mean femoral z and BMD scores were not significantly different. When males were compared separately, lumbar z and BMD values of the constitutionally thin group were found to be significantly lower than in the AN group. This difference was not significant for females. Conclusions: The difference between the male and female results of our study suggested two hypotheses. The significantly lower BMD values in constitutionally thin boys are attributed to their longer duration of low body mass index (BMI). Although the duration of low BMI is also longer for constitutionally thin girls, similar BMD values of AN and constitutionally thin female groups are attributed to the additional negative impact of estrogen deficiency on the bone health of girls with AN.

Background: Mainstay of therapy in the idiopathic nephrotic syndrome is glucocorticoids. Glucocorticoid induced osteoporosis is considered as most prevalent type of secondary osteoporosis. Only limited studies are conducted in tropical nations. Therefore our study is undertaken with objectives to evaluate Glucocorticoid therapy impact on bone health in Nephrotic Syndrome (NS) children by 2 different tools, namely urinary calcium and bone mineral density (BMD) by Quantitative ultrasound (QUS) and compare both the tools.Methods: Total 42 children with NS who completed minimum 12 weeks of Glucocorticoid therapy (6 weeks of daily regimen and minimum 6 weeks of alternate day regimen) were subjected to 24 hour Urinary calcium and Bone Mineral density by QUS at Tertiary health centre, Kalaburagi.Results: Out of 42 cases, 45.2 % had Osteopenia and 2.4% had osteoporosis, so 47.6% of them had BMD measured by QUS. Hypercalciurea was seen in 10 out of 42 cases (23.8%). In normal BMD group only 0.5% had hypercalciurea, Osteopenia group had 47.4% of cases and all osteoporosis group had hypercalciurea.Conclusions: Present study data concludes that children with NS treated with Glucocorticoids are at risk of Negative impact on bone health. Though both the tools detect impact of Glucocorticoids on bone health, BMD by QUS has better rate then urinary calcium in detecting negative effect of Glucocorticoid on bone health. As BMD by QUS decreases, Urinary calcium increases reflecting inverse relation between them.

Background: Ethnicity differentially modulate fracture risk prediction using FRAX™-bone mineral density (BMD). Objective: To compare FRAX™-BMD and trabecular bone score (TBS)-adjusted FRAX™ in the 10-year probability of fracture among Thai postmenopausal woman (PMW) with vertebral fracture (VF). Materials and Methods: The present study was a cross-sectional study conducted by retrospective review of medical records of PMW with VF older than 45 years undergoing lumbar and hip DXA scan. The authors excluded the PMW having been treated with metal implant at the spine, 3 or more lumbar VF, or cancer spreading to vertebral spine. The authors assessed the difference in means of normally distributed data by dependent sample t-test, the correlation between TBS and LS BMD by Pearson correlation, and the difference in proportions of PMW who met intervention threshold (IT) before and after TBS-adjusted FRAX™ by McNemar’s test. A p<0.05 was considered statistically significant. Results: Of the 119 patients, the mean age was 70.8±8.1 years. The mean 10-year probability of a hip fracture by TBS-adjusted FRAX™ was significantly higher than that by FRAX™-BMD with the mean difference of 0.44% (95% CI 0.13 to 0.76). The higher difference in means, using TBSadjusted FRAX™, was even significantly greater in the 10-year probability of major osteoporotic fractures. For either the IT of major osteoporotic fracture or hip fracture, TBS-adjusted FRAX™ resulted in four added PMWs who needed treatment, but without statistical significance. Conclusion: TBS-adjusted FRAX™ had a higher 10-year probability of fracture than FRAX™-BMD. Keywords: Trabecular bone score; FRAX™; Bone mineral density; Postmenopausal women; Osteoporosis

Background:Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), is considered as a risk factor of low bone mineral density (BMD). In fact, the prevalence of osteoporosis ranges from 17% to 41% in IBD patients. The possible contributing factors may include malabsorption, glucocorticoid treatment and coexisting comorbiditiesObjectives:The purpose of our work was to determine the frequency and the determinants of osteoporosis in patients with IBD and to assess whether there is a difference in BMD status between UC and CD.Methods:This is a retrospective study, over a period of 5 years (from January 2014 to December 2018) and including patients followed for IBD who had a measurement of BMD by DEXA. Clinical, anthropometric and densitometric data (BMD at the femoral and vertebral site) were recorded. The WHO criteria for the definition of osteoporosis and osteopenia were applied.Results:One hundred and five patients were collected; among them 45 were men and 60 were women. The average age was 45.89 years old. The average body mass index (BMI) was 25.81 kg/m2 [16.44-44.15]. CD and UC were diagnosed in respectively 57.1% and 42.9%. A personal history of fragility fracture was noted in 4.8%. Hypothyroidism was associated in one case. Early menopause was recorded in 7.6%. 46.8% patients were treated with corticosteroids. The mean BMD at the vertebral site was 1.023 g/cm3 [0.569-1.489 g/cm3]. Mean BMD at the femoral site was 0.920g/cm3 [0.553-1.286g / cm3]. The mean T-score at the femoral site and the vertebral site were -1.04 SD and -1.27 SD, respectively. Osteoporosis was found in 25.7% and osteopenia in 37.1%. Osteoporosis among CD and UC patients was found in respectively 63% and 37%. The age of the osteoporotic patients was significantly higher compared to those who were not osteoporotic (52.23 vs 43.67 years, p = 0.01). We found a significantly higher percentage of osteoporosis among men compared to women (35.6% vs 18.3%, p=0.046). The BMI was significantly lower in the osteoporotic patients (23.87 vs 26.48 kg/m2, p=0.035) and we found a significant correlation between BMI and BMD at the femoral site (p=0.01). No increase in the frequency of osteoporosis was noted in patients treated with corticosteroids (27.9% vs 21.6%, p=0.479). Comparing the UC and CD patients, no difference was found in baseline characteristics, use of steroids or history of fracture. No statistically significant difference was found between UC and CD patients for osteoporosis(p=0.478), BMD at the femoral site (p=0.529) and at the vertebral site (p=0.568).Conclusion:Osteoporosis was found in 25.7% of IBD patients without any difference between CD and UC. This decline does not seem to be related to the treatment with corticosteroids but rather to the disease itself. Hence the interest of an early screening of this silent disease.Disclosure of Interests:None declared

Objective: the clinical value of spinal quantitative CT (sQCT) and the structural patterns of the vertebral bone were studied Material and Methods: sQCT was performed on 246 patients with a mean age of 57 years for whom conventional lateral radiographies of the thoracic and lumbar spine were available. All patients were suffering from back pain of unknown etiology. the bone mineral density (BMD) of the midvertebral section of 3 lumbar vertebral bodies was determined by means of single-energy-(SE)-weighted QCT (85 kV). Spongiosa architecture and density profile analyses were made in the axial images. This was contrasted to BMD values ascertained in SE QCT. the mean BMD was compared to the number of fractures and the patients were divided into three groups: group I — no fracture; group II — one fracture; and group III 1 fracture Results: the mean BMD was: 134.3 (74.1–187.5) mg hydroxyapatite (HA)/ml in group I; 79.6 (58.6–114.3) mg HA/ml in group II; and 52.4 (13.1–79.1)mg HA/ml in group III. A significant deterioration in spongiosa structure was found with increasing demineralization: strongly rarefied patterns predominated in the fracture groups II and III Conclusion: sQCT provides a good risk assessment of the occurrence of vertebral body insufficiency fractures

Osteoporosis develops in women with chronic anorexia nervosa. To determine whether bone mass is reduced in younger patients as well, bone density was studied in a group of adolescent patients with anorexia nervosa. With single- and dual-photon absorptiometry, a comparison was made of bone mineral density of midradius, lumbar spine, and whole body in 18 girls (12 to 20 years of age) with anorexia nervosa and 25 healthy control subjects of comparable age. Patients had significantly lower lumbar vertebral bone density than did control subjects (0.830 ± 0.140 vs 1.054 ± 0.139 g/cm2) and significantly lower whole body bone mass (0.700 ± 0.130 vs 0.955 ± 0.130 g/cm2). Midradius bone density was not significantly reduced. Of 18 patients, 12 had bone density greater than 2 standard deviations less than normal values for age. The diagnosis of anorexia nervosa had been made less than 1 year earlier for half of these girls. Body mass index correlated significantly with bone mass in girls who were not anorexic (P &lt; .05, .005, and .0001 for lumbar, radius, and whole body, respectively). Bone mineral correlated significantly with body mass index in patients with anorexia nervosa as well. In addition, age at onset and duration of anorexia nervosa, but not calcium intake, activity level, or duration of amenorrhea correlated significantly with bone mineral density. It was concluded that important deficits of bone mass occur as a frequent and often early complication of anorexia nervosa in adolescence. Whole body is considerably more sensitive than midradius bone density as a measure of cortical bone loss in this illness. Low body mass index is an important predictor of this reduction in bone mass.
