Effects of vibration therapy on bone mineral density in postmenopausal women with osteoporosis

Background Jaw osteonecrosis possibly associated with the administration of bisphosphonates is expected to be treated with a non-pharmacologic approach. This study aimed to determine whether noninvasive, mechanically mediated vibration would inhibit the decline in bone mineral density （BMD） that follows menopause, enhance the BMD of the lumbar and femoral neck, and reduce chronic back pain in postmenopausal women with osteoporosis.
Methods A total of 116 postmenopausal women with osteoporosis participated in this study, and they were divided into groups A （66 patients） and B （50）. Group A received vibration treatment （Subjects vertically stand on the vibration platform, with a vibration frequency of 30 Hz, amplitude of 5 mm; they received the treatment five times per week, ten minutes each time and totally for six months）, whereas women of group B served as controls without any treatment. L2-4 BMD, bilateral femoral neck BMD, and body mass index （BMI） were recorded before the treatment or at the third and sixth months of the treatment respectively. After the ending of the treatment, the change of BMD in each group was compared and analyzed. Chronic back pain was evaluated by visual analogue scale （VAS） at baseline and the third and sixth months of the treatment.
Results Of the 116 women, 94 including 51 women from group A （（61.23±8.20） years） and 43 women from group B （（63.73±5.45） years）, completed the study. There were no significant differences in baseline characteristics including age, BMI, menopausal years, lumbar BMD, femoral neck BMD, and VAS between the two groups. The lumbar BMD of the 51 women in group A increased by 1.3% （P=0.034） after vibration treatment for 3 months and by 4.3% at the sixth month （P=0.000）. The lumbar BMD in group B was decreased at the third month, but there was not statistical significance （P〉0.05） At the sixth month, it was decreased by 1.9% （P 〈0.05）. The femoral neck BMD of the 51 women in group A was slightly in     

Salmon calcitonin in prevention of osteoporosis in maintenance dialysis patients

Background Renal osteodystrophy is one of the commonest complications of chronic renal failure. It may have a severe impact on the quality of life of patients on maintenance dialysis therapy. Besides post-menopausal women and elderly people, the dialysis patients are another high risk group. But at present, there is no research on how to prevent osteoporosis in maintenance dialysis patients. This study was conducted to observe the bone density of maintenance dialysis patients and to evaluate the clinical outcomes and safety of different administration dosage of salmon calcitonin to prevent osteoporosis in maintenance dialysis patients.
Methods One hundred and forty-eight patients on maintenance dialysis were involved in the 12-month, randomized, controlled trial. Fifty patients （experiment I group） received subcutaneous injection of salmon calcitonin （50 U） three times a week for 12 months. Fifty patients （experiment II group） received subcutaneous injection of salmon calcitonin （100 U） three times a week for 12 months. At the same time, both of them received oral calcium carbonate 1500 mg tid and rocaltrol 0.25 pg qn for 12 months. The control group only received oral calcium carbonate 1500 mg tid and rocaltrol 0.25 μg qn for 12 months. The levels of bone mass density （BMD） of the lumbar spine and femoral neck, serum intact parathyroid hormone （iPTH）, osteocalcin （OC）, calcium, phosphorus, alkaline phosphatase （ALP） were assessed at baseline and then again after 3, 6 and 12 months of treatment.
Results The values of BMD at the lumbar spine and femoral neck before the treatment were not significantly different from those 3, 6, and 12 months after the treatment in trial groups I and II （all P 〉0.05） and there were no significant differences in the BMD values at different time points between trial groups I and II. In the control group, the BMD values at the lumbar spine and femoral neck 3, 6, and 12 months after the beginning of trial were significantly lower than those be

Symptomatic osteonecrosis of the femoral head after adult orthotopic liver transplantation

Background  With the increase of survival in liver transplantation recipients, more patients are at a high risk of developing osteonecrosis, especially in the femoral head, due to immunosuppressive treatment. The purpose of this study was to report the incidence, possible risk factors, and outcome of symptomatic osteonecrosis of the femoral head (ONFH) in adult patients with current immunosuppressive agents and individual protocol after liver transplantation in China.

Methods  A retrospective analysis was performed on 226 adult patients who underwent orthotopic liver transplantation (OLT) at a single liver transplantation institution between January 2004 and December 2008. The posttransplant survival time (or pre-retransplantation survival time) of all the patients were more than 24 months. The possible pre- and post-transplantation risk factors of symptomatic ONFH were investigated and the curative effects of the treatment were also reported.

Results  The incidence of ONFH was 1.33% in patients after OLT. ONFH occurred at a mean of (14±6) months (range, 10–21 months) after transplantation. Male patients more often presented with osteonecrosis as a complication than female patients. The patients with lower pre-transplantation total bilirubin and direct bilirubin levels (P <0.05). There was no difference in the cumulative dose of corticosteroids or tacrolimus between the patients with or without symptomatic ONFH. Patients were treated either pharmacologically or surgically. All patients showed a nice curative effect without major complications during the 18–63 months post-treatment follow up.

Conclusions  The symptomatic ONFH does not occur commonly after adult OLT in the current individual immunosuppressive protocol in China.

A randomized,multicenter controlled trial to compare the efficacy of recombinant human parathyroid hormone （1-34） with elcatonin in postmenopausal women with osteoporosis in China

Background Recombinant human parathyroid hormone （1-34） （rhPTH （1-34）） given by injection is a new seventh class drug of biological products, which is prepared by adopting gene recombination technique, rhPTH （1-34） is mainly used to treat osteoporosis, especially for postmenopausal women. This study compared the clinical efficacy and safety of rhPTH （1-34） with elcatonin for treating postmenopausal women with osteoporosis in 11 urban areas of China. Methods Two hundred and five women with osteoporosis were enrolled in a 6-month, multicenter, randomized, controlled study. They were randomized to receive either rhPTH （1-34） 20 ug （200 U） daily or elcatonin 20 U weekly. Lumbar spine （L1-4） and femoral neck bone mineral density （BMD）, as well as biochemical markers of bone turnover were measured. Adverse events were recorded. Results rhPTH （1-34） increased lumbar BMD significantly more than did elcatonin at 3 months and 6 months （2.38% vs 0.59%, P 〈0.05; 5.51% vs 1.55%, P 〈0.01）, but there were no significant increases of BMD in these two groups at femoral neck. There were larger mean increases in bone markers in the rhPTH （1-34） group than in the elcatonin group at 3 months and 6 months （serum bone-specific alkaline phosphatase （BSAP） 36.79% vs 0.31%; 92.42% vs -0.17%; urinary N-telopeptide/creatinine （NTX/Cr） 48.91% vs -5.32%; 68.82% vs -10.86%）. Both treatments were well tolerated and there were no significant differences detected between the two groups in the proportion of any adverse events and any serious adverse events （67.0% vs 59.0%; 0 vs 0）. Conclusions rhPTH （1-34） has more positive effects on bone formation, as shown by the larger increments of lumbar BMD and bone formation markers, than elcatonin, with only mild adverse events and no significant change in the liver, kidney or hematological indices.     

糖皮质激素应用患者血清骨钙素与骨密度的相关性

目的探讨糖皮质激素（GCs）应用患者血清骨钙素与腰椎、股骨骨密度的相关性。方法选取长期应用GCs治疗的22例患者（其中侣例骨密度异常）,采用ELISA法测定其治疗前及治疗后3、6个月的血清骨钙素水平,同时采用双能X线吸收法测定其治疗前及治疗后3、6个月的腰椎、股骨骨密度,比较治疗前后血清骨钙素及腰椎、股骨骨密度的变化,并对血清骨钙素和腰椎、股骨骨密度作相关性分析。结果骨密度异常的18例患者,治疗3个月后9例来院复查骨密度。其中8例复查血清骨钙素;治疗6个月后14例来院复查骨密度,其中9例复查血清骨钙素。与治疗前比较,治疗3个月后腰椎及股骨骨密度均未发生明显变化（均P〉0,05）,但血清骨钙素明显降低（P〈0.05）;治疗6个月后腰椎骨密度明显升高（P〈0.05）、血清骨钙素明显降低（P〈0,05）,但股骨骨密度并无明显变化（P〉0.05）。GCs应用患者血清骨钙素水平与腰椎及股骨骨密度显著负相关（r=-0．41、-0．38,P〈0.05或0．01）。结论GCs应用患者经二膦酸盐联合钙尔奇D治疗后,其骨转换变化的敏感性高于骨密度。
