BACKGROUND: Type 2 diabetes and osteoporosis are widespread diseases in the middle-aged and elderly people. Most studies of osteoporosis in patients with type 2 diabetes have been performed in women; meantime risk factors for lowering bone mineral density (BMD) in men have been little studied.AIMS: to identify risk factors for decreased BMD at the lumbar spine, femoral neck and forearm in men with type 2 diabetes.METHODS: Eighty two men from 50 to 75 years old, with duration of diabetes for at least one year, were included in the study. Individuals with known risk factors for secondary osteoporosis were not included. Twenty-three men with normal BMD having no diabetes or obesity were acted as control. The T-score at the lumbar spine, femoral neck and forearm of a non-dominant arm, as well as body composition parameters, were evaluated by dual-energy X-ray absorptiometry. The levels of hormones that affect bone metabolism (parathyroid hormone, free testosterone, 25-OH vitamin D) were measured in blood serum by ELISA. Risk factors for reducing BMD were identified using multivariate regression analysis and receiver operating characteristic (ROC) curves.RESULTS: Among patients with diabetes, 49 individuals had normal BMD and 33 showed decreased T-score values (<-1 SD). Free testosterone <5.92 pg/ml was predictor for decreased BMD at the lumbar spine (OR=4.4, p=0.04). For femoral neck, the risk factors were body weight <95.5 kg (OR=2.8, p=0.04), total fat mass <27 kg (OR=3.3, p=0.03), truncal fat mass<17.5 kg(OR=4.5, p=0.006), android (central abdominal) fat mass <3.2 kg(OR=4.0, p=0.01), gynoid (hip) fat mass <3.5 kg(OR=3.3, p=0.02), and lean mass <59 kg(OR=3.0, p=0.04). Risk factors for reduced BMD at the forearm were diabetes duration>15.5 years (OR=3.7, p=0.03) and HbA1c <8.15% (OR=3.8, p=0.03). Parathyroid hormone and 25-OH-vitamin D did not predict BMD independently.CONCLUSIONS: In men with type 2 diabetes, low free testosterone is a risk factor for decreased BMD in the lumbar spine, and diabetes duration is a risk factor for decreased BMD in the forearm. The presence of obesity is associated with an increase in BMD in the femoral neck; a high HbA1c is associated with an increase in BMD in the forearm.

Background:Radiofrequency echographic multi spectrometry (REMS) is an innovative radiation-free approach for the assessment of bone mineral density (BMD) at axial sites. The principle of this technology is based on the analysis of native raw unfiltered ultrasound signals, the so called radiofrequency ultrasound signals, acquired during an echographic scan of the lumbar spine and/or femoral neck. [1]. A previous published study showed a high degree of correlation between the T-score values provided by the two techniques-REMS and dual energy X-ray absorptiometry for both lumbar spine and femoral neck [2]. REMS software outputs information about BMD (g/cm2), T-scores, Z-scores [standard deviations (SD)], percentage of body fat and basal metabolic rate [BMR (kcal/daily)] [3].Objectives:The aim of the current study is to investigate the multivariate significant risk factors for reduced BMD through REMS technology.Methods:In this study, a total of 273 women with mean age 62 years (yrs.) ± 12 yrs. (range 25-88 yrs.) underwent REMS assessments. Subjects were divided into two groups after acquiring information about the spinal T-scores: 1st group with T-scores ≥-1 SD and 2nd group with T-scores <-1 SD. Age, weight, height, body mass index (BMI), basal metabolic rate (BMR), body fat and menopausal status were the risk factors included in the multivariate statistical analyses. Binary logistic regression was used to assess which are the significant risk factors for T-score <-1 SD. Youden’s indices were calculated for selecting the cut-off points for each risk factor.Results:273 women had mean weight of 70.5 kg. ± 15.7 kg. (range 39.4-127 kg.), mean height 157.1 cm. ± 8.8 cm. (range 100-182 cm.) and mean body mass index (BMI) 28.6 kg/cm2 ± 6.1 kg/cm2 (range 14.9-47.5 kg/cm2). The mean body fat of the subjects was 37.8% ± 8.8% (range 9-52%) and the mean BMR was 1274.01 kcal/daily ± 163.17 kcal/daily (range 929.7-1908.4 kcal/daily). 260 women (95.2%) were attributed to postmenopausal. Age (p=0.000), BMI (p=0.015), menopause (p=0.006) and BMR (p=0.000) were the multivariate significant risk factors for T-score <-1 SD. Odds ratio for the risk factor age was 1.16, so each added year of the women’s age increased the risk for T-score <-1 SD by 1.16%. Women over the age of 65 yrs. showed the highest risk for spinal T-score <-1 SD. The odds ratio of the menopause as a risk factor for spinal T-score <-1 SD was 9.54, so postmenopausal women showed about 9.5 times higher risk of T-score <-1 SD of the lumbar spine than women who still have their period. The increase of BMI by one kg/cm2 decreased the probability of spinal T-score <-1 SD by 0.15% and the increase of BMR by one kcal/daily decreased this probability by 0.02%. Women with BMI above 28.63 kg/cm2 and those with BMR >1331.75 kcal/daily were unlikely to develop spinal T-score <-1 SD.Conclusion:In the current study, multivariate regression analysis was used to develop a specific REMS-based risk prediction model for spinal BMD, corresponding to T-score <-1 SD. Postmenopausal women over age of 65 yrs. with BMI lower than 28.63 kg/cm2 and BMR <1331.75 kcal/daily were at the highest risk for T-score <-1 SD of the lumbar spine.References:[1]Pisani P, Renna MD, Conversano F, Casciaro E, Muratore M, et al.

Abstract Background Despite the increased fracture risk, bone mineral density (BMD) is variable in type 1 (T1D) and type 2 (T2D) diabetes mellitus. We aimed at comparing independent BMD predictors in T1D, T2D and control subjects, respectively. Methods Cross-sectional case-control study enrolling 30 T1D, 39 T2D and 69 age, sex and body mass index (BMI) – matched controls that underwent clinical examination, dual-energy X-ray absorptiometry (BMD at the lumbar spine and femoral neck) and serum determination of HbA1c and parameters of calcium and phosphate metabolism. Results T2D patients had similar BMD compared to T1D individuals (after adjusting for age, BMI and disease duration) and to matched controls, respectively. In multiple regression analysis, diabetes duration – but not HbA1c- negatively predicted femoral neck BMD in T1D (β= -0.39, p = 0.014), while BMI was a positive predictor for lumbar spine (β = 0.46, p = 0.006) and femoral neck BMD (β = 0.44, p = 0.007) in T2D, besides gender influence. Age negatively predicted BMD in controls, but not in patients with diabetes. Conclusions Long-standing diabetes and female gender particularly increase the risk for low bone mass in T1D. An increased body weight partially hinders BMD loss in T2D. The impact of age appears to be surpassed by that of other bone regulating factors in both T1D and T2D patients.

Objectives: Low bone mass is a common disorder in elderly population which predisposes to fracture with minimal trauma. This study was performed to find out the association between the Body Mass Index (BMI) and Bone Mineral Density (BMD) in postmenopausal women.Materials and Methods: This cross sectional study was carried out at Institute of Nuclear Medicine and Allied Sciences Comilla and Mitford, Dhaka over a period of 12 months from January 2013 to December 2013. A total 93 postmenopausal women were enrolled for this study. All postmenopausal women underwent a BMD scan of femoral neck and lumbar vertebrae using a Dual Energy X-ray Absorptiometry (DEXA). Participants were categorized into three groups according to their age and BMI. BMD were expressed base on T-score according to WHO criteria. The relation among BMI, age and BMD were assessed.Results: The results of this study showed that the mean age of the study group was 57.13±7.49 years with range of 46 to 75 years. The most postmenopausal women were in age group 55-65years. The mean BMI of the study subjects were 24.18±5.08 kg/m2 with a range of 15.62 to 36.20 kg/m2. Among 93 subjects osteopenia was greater at lumbar spine (45.2%) with T-score mean±SD-1.83±0.33 and osteoporosis at femoral neck (51.6%) with T-score mean ±SD-3.36±-0.67. Pearson’s correlation coefficient test showed inverse relationship between age and BMD both lumbar spine (r = -0.301, p = 0.003) and femoral neck (r = -0.303, p=0.003) whereas the positive relation between BMI and BMD both at lumbar spine (r=0.338, p=0.001) and femoral neck (r =0.343, p=0.001). These showed that with advancing age, BMD decreases and the risk of osteoporosis increases and with increasing BMI, BMD increases and risk of osteoporosis decreases.Conclusion: The findings of this study portrait that aging and low BMI are risk factors associated with bone loss. So preventive measure should be taken for high risk post menopausal women.Bangladesh J. Nuclear Med. 17(2): 138-141, July 2014

Introduction: Osteoporosis and Diabetes Mellitus (DM) are common medical conditions in the society with an increasing prevalence in elderly people. Osteoporosis is more common in female than male and postmenopausal women are vulnerable to it.   Objective: The aim of this study was to verify the effect of type-2 diabetes mellitus on bone mineral density in postmenopausal women and, thereby, to evaluate the risk of osteoporosis in them.   Materials and Methods: This cross-sectional study was carried out at National institute of Nuclear Medicine and Allied Sciences (NINMAS), BSMMU campus, Shahbagh, Dhaka, over a period of one year. 175 postmenopausal women were enrolled as study subjects, among them 72 (41.10%) were diabetic and rest 103 (59.90%) were nondiabetic and they were assigned as Group-I and Group-II respectively. The bone mineral density (BMD) was measured by central DEXA device at lumbar spines and left femoral neck of each study subject.   Results: The mean (±SD) ages of group-I and group-II were 58.79 (±8.06) and 58.27 (±8.39) respectively with an age range of 45 to 75 years in both cases. A total of 30 (41.66%) patients in diabetic group (group-I) and 40 (38.83%) patients in non-diabetic (group-II) had osteoporosis at lumbar spines. On the other hand, 40 (56.94%) patients in group-I and 58 (56.31%) patients in group-II had osteoporosis at femoral neck. The Odds Ratios of osteoporosis for lumbar spines and femoral. neck were 1.125 and 1.026 respectively. The differences of frequencies of osteoporosis between group-I and group-II were not statistically significant at any anatomical site and the association between osteoporosis and type-2 diabetes mellitus was not significant. According to Odds Ratio type-2 diabetes mellitus was not a risk factor for developing osteoporosis in postmenopausal women.   Conclusion: Postmenopausal women are prone to develop osteoporosis and type-2 diabetes mellitus may have adverse influence on osteoporosis, which was supported by few previous studies. This study could not establish any significant effect of type-2 diabetes mellitus on osteoporosis in postmenopausal women.Bangladesh J. Nuclear Med. 18(1): 21-26, January 2015

CONTEXT AND OBJECTIVES: Controversy exists regarding the relationship between atherosclerosis and osteoporosis. The aim of this study was to determine the relationship between intima-media thickness (IMT) of the common carotid artery (CCA), presence of calcified atherosclerotic plaques and bone mineral density (BMD) evaluated by dual energy X-ray absorptiometry (DXA), in postmenopausal women. DESIGN AND SETTING: Cross-sectional study at Second Internal Medicine Clinic, Cluj-Napoca, Romania. METHODS: We studied the IMT (left and right CCA and mean IMT) and T-score (lumbar spine L2-L4, femoral neck and total hip) in 100 postmenopausal women (mean age 64.5 years). The presence of calcified atherosclerotic plaque and osteoporotic vertebral fractures was also noted. RESULTS: IMT in the left and right CCA and mean IMT were significantly associated with T-score measured for the lumbar spine L2-L4, femoral neck and total hip, with lower T-score, in the osteoporotic group than in the normal and osteopenic groups (P < 0.05). IMT had a significantly negative correlation with the lumbar spine T-score and femoral neck T-score; and mean IMT with lowest T-score. Mean IMT (P < 0.001), high blood pressure (P = 0.005) and osteoporotic vertebral fractures (P = 0.048) showed statistical significance regarding the likelihood of developing atherosclerotic plaque. CONCLUSIONS: In women referred for routine osteoporosis screening, the relationship between CCA, atherosclerosis and osteoporosis can be demonstrated using either cortical or trabecular BMD. Vertebral fractures may be considered to be a likelihood factor for atherosclerotic plaque development.

Abstract Introduction: Dual-energy X-ray Absorptiometry (DXA) is considered the gold standard examination for the evaluation of bone mineral density (BMD). However, it is known that some conditions, such as arthrosis, vertebral collapse, or vertebroplasty, result in an overestimation of the BMD measured by DXA. Conversely, Radiofrequency Echographic Multi-Spectrometry (REMS) technology is able to automatically discard signals related to bone artifacts, such as calcifications or osteophytes, thanks to the identification of unexpected spectral features (Diez-Perez et al. 2019). The aim of this work is to assess the performance of REMS technology in patients with bone alterations that could alter the densitometric examination. Materials: The bone densitometry exams, both REMS and DXA, of patients with evidences of bone alterations at lumbar vertebrae or femoral neck were analysed. Written patient informed consent was obtained before the scans. Results: Eighty-seven patients with spinal artifacts, including 22 patients with vertebroplasty, 26 patients with bone fracture and 38 patients with osteo-arthrosis were considered. At lumbar spine, the mean BMD and T-score values assessed by REMS was lower than the ones measured by DXA. Moreover, the results obtained by the two technologies were not correlated. On the contrary, the BMD and T-score values measured by REMS and DXA at the femoral site were highly correlated (p&lt;0.01), as well as BMD and the T-score values measured by DXA at the femoral neck and by REMS at the lumbar spine (p&lt;0.01). As concerning artifacts involving femoral site, a patient with an intramedullary gamma nail positioned following a displaced pertrochanteric fracture of the left femur underwent a DXA scan of the right femur and a REMS scan of both femurs. A diagnosis of osteoporosis at the right femur was posed by both technologies. At the left femur with intramedullary gamma nail, REMS only made a diagnosis of osteoporosis highly corresponding with the one performed at right femur. Conclusions: The results from the patient series with spinal artifacts and the clinical case with femoral intramedullary gamma nail show the ability of REMS to evaluate anatomical sites that would not be assessable by DXA, such as in case of implanted nails, or that would give unreliable higher BMD values, such as in case of vertebroplasty, osteo-arthrosis and bone fracture.
