Denosumab Treatment

Background: Denosumab is a highly effective and safe first-line treatment for osteoporosis. Primary hyperparathyroidism is a prevalent condition found in patients with osteoporosis. However, data regarding effectiveness of denosumab treatment in patients with PHPT are scarce. Aims: To estimate the comparative effects of denosumab to treat postmenopausal osteoporosis (PMO) and osteoporosis caused by primary hyperparathyroidism (PHPT) or glucocorticoid-induced osteoporosis (GIOP) in postmenopausal women in routine clinical practice. Materials and methods: Retrospective study based on the medical card records. Patients over 50 years of age with verified osteoporosis (based on bone mineral density (BMD) T-score ≤ -2.5 SD and/or low-trauma fracture), who had at least 3 denosumab injections were included in the study. Results: 162 patients were included and divided into three groups according to the etiology of osteoporosis. The first group consisted of postmenopausal women with osteoporosis (PMO) [(n=85); median age 70 [64;78]]. Patients with glucocorticoid-induced osteoporosis (GIOP) were enrolled in the second group [(n=16); male to female ratio =1:15; median age 60 [57,8; 66,3]]. The third group consisted of patients with PHPT and osteoporosis [(n=61); male to female=2:59; median age 68 [63; 75]]. Among all patients, denosumab treatment significantly increased BMD and decreased serum levels of calcium and CTx compared with baseline. PMO: the median increase in BMD according to the T-score was L1-L4 0,6 (p<0,001), femoral neck 0,2 (p<0,001); serum calcium -0,04 (p=0,004). PHPT: the median increase in BMD according to the T-score was L1-L4 0,6 (p<0,001), femoral neck 0,2 (p<0,001); radius 33% 0,25 (p=0,002), serum calcium -0,04 (p<0,001). In patients with GIOP, denosumab increased BMD in the lumbar spine L1-L4 0,5 (p=0,004). There was no difference in BMD increase or in levels of bone turnover suppression between the groups. A marked decline in levels of serum calcium was noted among patients with GFR less than 60 ml / min / 1.73 m2 (median Δ Са serum=0,24 p<0,001), compared to patients without CKD (median Δ Са serum=0,08 p<0,001).Conclusion: Denosumab treatment is similarly effective for increasing BMD and decreasing bone turnover markers in patients with PMO and PHPT among postmenopausal women. The hypocalciemic effect of denosumab is most significant in subjects with PHPT.

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

The Relationship

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.

Bone Condition

<p><strong><em>Objective:</em></strong><strong> </strong>Bone loss is a major complication of primary hyperparathyroidism (PHPT), and the extent of bone loss is an important factor for parathyroidectomy. Studies focused on this issue of bone loss in subjects with PHPT are quite rare in our country. This study will help the physicians to take proper action by giving an exact reflection of bone condition in subjects with PHPT. The purpose of this study was to evaluate the bone condition by measuring Bone Mineral Density (BMD), in subjects with PHPT using Dual Energy X-ray Absorptiometry (DEXA) and compare these findings with individuals without PHPT.</p><p><strong><em>Patients and Methods:</em></strong><strong> </strong>It was an analytic cross sectional study (group comparison) carried out at National Institute of Nuclear Medicine and Allied Sciences (NINMAS) BSMMU campus, Dhaka from July 2015-December 2016. Subjects of PHPT diagnosed by biochemical evaluation (increased serum calcium and parathyroid hormone concentrations), between age ranges 15-45 years were selected as group-A. Individuals without biochemical evidence of PHPT or other major illness causing bone loss were selected as comparison group or as group-B. The subjects underwent BMD test by DEXA at lumbar spines from L1-L4 vertebra and the left femoral neck using Norland XR-46 densitometer. BMD was classified according to WHO criteria. Data presented on categorical form were analyzed using chi-squared test. While the data presented on continuous scale were analyzed using student’s t-test. In each analysis, level of significance was 5% and P value &lt;0.05 was considered significant. Data were processed and analyzed with the help of computer software SPSS, version 20.</p><p><strong><em>Results:</em></strong><strong> </strong>Total number of 90 subjects were selected for this study, 45 subjects with PHPT were in group-A and equal number of subjects without PHPT were in group-B. The findings derived from data analysis showed, a significantly more male participants in group-A. The mean age of group-A and group-B was 37.24 ± 8.03 years and 38.20 ± 5.74 years respectively. Mean BMI of group-A was 25.10 ± 4.35 kg/m<sup>2  </sup>in compare to 29.43 ± 5.17 kg/m<sup>2</sup> in group-B. Higher BMI was noted in both groups. PHPT subjects with high BMI had low BMD. BMD expressed in absolute value (gm/cm<sup>2</sup>) and T score. BMD was significantly low in group-A (with PHPT) than in group-B (without PHPT), (p&lt;0.0001). In group-A, prevalence of low BMD was 62.2% (osteopenia 37.8%  and osteoporosis 24.4%)  at lumbar spine and 84.5% (osteopenia 35.6% and osteoporosis 48.9%) at femoral neck. PHPT subjects had significant difference in both T score and BMD between lumbar spine and femoral neck.</p><p><strong><em>Conclusion:</em></strong><strong> </strong>Primary hyperparathyroidism (PHPT) is shown to be associated with significantly reduced BMD especially at femoral neck. Thus, an increased fracture risk should consider if it is left untreated.</p><p>Bangladesh J. Nuclear Med. 20(2): 129-135, July 2017</p>

Significant Change

Introduction The least significant change (LSC) is a term used in individuals in order to evaluate whether one measurement has changed significantly from the previous one. It is widely used when assessing bone mineral density (BMD) scans. To the best of our knowledge, there no such estimate available in the literature for patients with disorders of calcium metabolism. Our aim was to provide an estimate of the least significant change for albumin-adjusted calcium in patients with normocalcaemic hyperparathyroidism (NPHPT) and primary hyperparathyroidism (PHPT). Methods We used the within-subject standard deviatio calculated in a population of NPHPT and PHPT patients and multiplied it by 2.77. Results The LSC for NPHPT and PHPT were found to be 0.25 and 0.24 mmol/L, respectively (1.00 and 0.96 mg/dL). In clinical practice, the value of 0.25 mmol/L could be used. Discussion The least significant change given, could be used in two ways in these patients. First, it gives a range to which values are expected. This can provide some reassurance for the patient and the physician in cases of intermittent hypercalcaemia. Moreover, it can be a marker of whether an individual has an actual significant change of his calcium after parathyroid surgery.
