Spectacular improvement in vitamin D status in elderly osteoporotic women: 8-year analysis of an osteoporotic population treated in a dedicated fracture liaison service.

UNLABELLED: In a population of postmenopausal women with a fragility fracture, we found a drastic reduction in the proportion of women with severe (<25 nmol/L) and moderate (25 to 75 nmol/L) hypovitaminosis D, especially from 2009 onwards. These results show that supplementation has been very widely integrated into current practice. INTRODUCTION: Vitamin D (25(OH)D) is essential for bone health. In institutionalised osteoporotic women, it reduces the risk of fragility fractures. Numerous articles suggesting the possibility of extraosseous effects have generated a growing number of publications and recommendations on more widespread administration, to limit the risks of moderate or severe hypovitaminosis D. We assessed the impact on clinical practice of these recommendations concerning 25(OH)D supplementation in elderly at-risk populations. METHODS: A total of 1486 postmenopausal osteoporotic women were seen in the context of a fracture liaison service (i.e. a rheumatology consultation following a peripheral fragility fracture), between May 2005 and December 2012. Of these, 1107 had a 25(OH)D assay (femur, n = 520; humerus, n = 207; wrist, n = 380). RESULTS: The average age of the total population was 76.7 ± 9.9 years, while for women with an available 25(OH)D assay, the average age was 75.1 ± 11.8 years. The average 25(OH)D (nmol/L) level was similar for the three fracture sites: femur, 30 ± 36.2; humerus, 27.5 ± 24; and wrist, 31 ± 26. A drastic reduction in the proportion of women with severe (<25 nmol/L) and moderate (25 to 75 nmol/L) hypovitaminosis D was observed, especially from 2009 onwards, with a mean prevalence of 69 and 30 % respectively before that year and 35 and 52 % thereafter. Conversely, the proportion of women with 25(OH)D at the threshold value of 75 nmol/L increased from 1.2 to 24 %. Overall, mean serum 25(OH)D levels were significantly higher when comparing the two periods 2005-2008 and 2009-1012 (17.6 ± 14.6 and 48.4 ± 39.2 nmol/L, respectively; p < 0.0001). CONCLUSION: These results show that supplementation has been very widely integrated into current practice. We can expect it to yield beneficial effects in osseous and extraosseous terms in osteoporotic women, particularly the very elderly.

[Analysis of the effects of different medicines on hypercoagulability state variations of femoral shaft fracture and after its operation].

OBJECTIVE: To explore the role of Tong Mai Tang & Lornoxicam on the serum concentrations of tumor necrosis factor alpha (TNF-alpha), interleukin (IL-6) , D-dipolymer( D-Di), Platelet count (PLC) in treatment of femoral shaft fracture among period surgery time. METHODS: We selected 120 cases of traumatic femoral shaft fracture patients according to the inclusion criteria and exclusion criteria, which were randomized dividend into four groups (I, II, III, IV respectively) of the same size based on the random number table method of 30 patients each. Therapeutic methods of four groups following as: Group I, Tpanax Notoginseng Pills PO; Group II, Tpanax Notoginseng Pills PO, Lornoxicam For Injection, 8 mg IM; Group III, Tpanax Notoginseng Pills PO, Tong Mai Decoctions 200 mL PO; Group IV, Tpanax Notoginseng Pills PO, Lornoxicam For Injection 8 mg IM, Tong Mai Decoctions 200 mL PO. The above medications were administered to the four groups after admission to hospital the next day. Peripheral blood samples were taken for immune determination of pro-inflammatory cytokines of TNF-alpha, IL-6, D-Di, PLC in blood serum on the 2nd and 6th day before operation and on the 8th and 13th day after operation in the morning. And all patients received liver and kidney function examination 2nd and 13th day after admission. Analysis of variance and least significant difference-test were done with the help of SPSS 17.0 statistic software. RESULTS: The difference among four groups in TNF-alpha and IL-6 were significant (P < 0.05). And there were also significant statistic difference between group II/III/IV and group I group (P < 0.05). But the difference between group II and group III was insignificant (P > 0.05). However, the group contrast result between group IV and group II/III had statistics difference (P < 0.05). The difference in D-Di PLC at 6th day and 8th day were significant (P < 0.05). The group comparisons in group I/II/IV were also significant. There were non-statistics significance in group II compared 6th day/8th day with 2nd day (P > 0.05). The comparison between the 13th day with the first three time sections had statistics significance. And there were statistics significance at the 13th day between group IV and group II (P < 0.05). CONCLUSION: The serum concentrations of TNF-alpha, IL-6, D-Di and PLC level were significantly increased in peroperative period, These results seem to indicate that the Tong Mai Decoctions & Lornoxicam may play an important role in inhibiting the release of TNF-alpha, IL-6, D-Di and PLC into the blood stream and decreasing the incunabula complication at early traumatic stage. The Tong Mai Decoctions & Lornoxicam was the worth promoting screened China and the West union medication combination.

[Effects of Tongmai decoction on the perioperative changes of plasma TNF-alpha and IL-6 in patients with femoral fractures].

OBJECTIVE: To explore the effects of Tongmai decoction on the perioperative changes of serum concentrations of tumor necrosis factor alpha (TNF-alpha) and interleukin (IL)-6 in patients with femoral fractures, and conform the effectiveness of Tongmai decoction on inflammatory factors in patients with femoral fractures, providing the theoretical evidence for the clinical use of Tongmai decoction. METHODS: From October 2007 to May 2009, 60 patients with closed traumatic femoral fractures were selected according to the inclusion criterias and exclusion criterias. All the patients were randomly divided into three groups (group A, group B and group C). Twenty patients in group A (Tpanax Notoginseng pill group), 13 patients were male and 7 patients were female; ranging in age from 20 to 45 years, averaged 32.0 years; the disease course ranged from 2.0 to 26.0 h, with an average of 9.5 h. Twenty patients in group B (Tpanax Notoginseng pills and Lornoxicam injection group),12 patients were male and 8 patients were female; ranging in age from 23 to 42 years, averaged 31.0 years; the disease course ranged from 3.5 to 25.0 h, with an average of 13.6 h. Twenty patients in group C (Tpanax Notoginseng pill, Lornoxicam injection and Tongmai decoction group), 14 patients were male and 6 patients were female; ranging in age from 21 to 44 years, averaged 31.5 years; the disease course ranged from 4.6 to 29.0 h, with an average of 13.3 h. Among all the patients, 42 patients with fractures were fixed with femoral intramedullary nailing, and other 18 patients with femoral locking plate fixation. The patients in group A took Tpanax Notoginseng pills orally, 4 g each time and twice daily; the patients in group B took Tpanax Notoginseng pills orally as group A, and at the same time received intramuscular injection of Lornoxicam, 8 mg each time and once daily; the patients in group C took Tpanax Notoginseng pills orally and received intramuscular injection of Lornoxicam as group B, and at the same time took Tongmai decoction (R ) orally, 200 ml each time and twice daily. The above medications were administered to the three groups on the second day after admission to hospital. Peripheral blood samples were taken for determination of pro-inflammatory cytokines of TNF-alpha and IL-6 in blood serum on the 2nd and 6th days before operation and on the 8th and 13th days after operation. And all the patients were evaluated liver and kidney function at the 2nd and 7th days after admission. Analysis of variance and least significant difference-test were done with the help of SPSS 17.0 statistic software. RESULTS: The differences among three groups of TNF-alpha and IL-6 in blood serum at the 2nd day after admission and 2 days after operation had no statistical significance (P > 0.05). The TNF-alpha and IL-6 levels among 3 groups had statistical differences at the 7th day after admission and at the 7th day after operation (P < 0.05, P < 0.01). There were significant differences of TNF-alpha and IL-6 levels between the 7th day after admission and the 2nd day after admission, the 7th day after operation and the 2nd day after admission (P < 0.01). There were also significant differences of TNF-alpha and IL-6 levels between group C compared with group A and B at the 7th day after admission and the 7th day after operation(P < 0.05, P < 0.01). CONCLUSION: The serum concentrations of TNF-alpha and IL-6 level significantly increased in perioperative period. The results indicate that the Tongmai decoction may play an important role in inhibiting the release of TNF-alpha and IL-6 into the blood stream and decreasing the incunabula complication at early traumatic stage.

Importance of vitamin D in hospital-based fracture care pathways.

OBJECTIVES: This project was developed to identify ways to support hospital-based improvements for the identification and management of osteoporosis following treatment of a fragility fracture. DESIGN: This is a retrospective review of medical records of sets of consecutive patients who were admitted for surgical treatment of fragility fracture following introduction of several versions of admission and discharge care pathways. Effectiveness of the admission pathway was defined as % subjects with measurement of serum 25- hydroxyvitamin D (25(OH)D) during hospitalization; effectiveness of the discharge pathway was defined as % subjects with documentation of instructions for calcium and/or vitamin D supplementation. SETTING: This study reviewed medical records of patients admitted to hospital for surgical treatment of a fragility fracture. PARTICIPANTS: Medical records were evaluated for 98 patients older than 50-years who were admitted with a fragility fracture of the hip or femur. MEASUREMENTS: Medical records were reviewed for the % subjects with documentation of an in-hospital order for serum 25(OH)D and with documentation of instructions to patients upon discharge concerning calcium and vitamin D intake. Median value of serum 25(OH)D was calculated. RESULTS: In accordance with the admission pathway, serum 25(OH)D was measured in 37% (36/98). The median 25(OH)D level was 19.5 ng/mL; 78% were vitamin D insufficient [serum 25(OH)D < or = 32 ng/mL] and 58% were vitamin D deficient [serum 25(OH)D < or = 20 ng/mL]. In accordance with the discharge pathway, 74% (71/96) were discharged on calcium and/or vitamin D. CONCLUSION: The high prevalence of vitamin D insufficiency (78%) observed in this study affirms the importance of incorporating vitamin D supplementation in hospital-based fracture care pathways. The discharge pathway was more effective than the newer admission pathway, a finding attributable to effects of familiarity, retraining, and introduction of computer-prompts. These evolving pathways represent a much-needed paradigm shift in the care of fragility fracture patients.

The effect of chemotherapy on soft tissue and bone healing in the rabbit model.

UNLABELLED: The effect of chemotherapy on soft tissue and bone healing was studied in a rabbit femoral fracture model. Adriamycin was administered at various intervals preoperatively. Results were compared against a control group in which adriamycin was omitted. Post-chemotherapy blood count profiles were monitored. All animals were operated on with a standard skin incision, osteotomy of the femur and fixation with an intramedullary wire. Soft tissue was assessed with daily clinical scoring and tested for wound breaking strength at two weeks postoperatively. Bone healing was assessed at the time of sacrifice six weeks postoperatively by four-point bending to failure. Clinical scoring of wounds did not show significant differences between control and adriamycin-treated groups. Results of wound breaking strength and four-point bending to failure showed significant impairment for animals given adriamycin four and seven days preoperatively, and no significant impairment when given 14 days preoperatively. CLINICAL RELEVANCE: Contrary to previous studies, our results suggest that it is feasible to combine neoadjuvant chemotherapy and early surgery without compromise of soft tissue healing. Our results show that adriamycin impairs bone healing. We postulate that adriamycin has a temporary and reversible inhibitory effect on bone biology. The clinical implications of these findings are discussed.

Effects of 1,24 dihydroxyvitamin D3 and calcitonin on fracture healing in adult rats.

Calcitonin and 1.25(OH)2D3 have opposite effects on the serum concentrations of Ca and P, as well as on bone resorption, and can be observed in the process of healing of standardized fracture in adult rats. The rats given 1.25(OH)2D3 had a stronger fracture callus and slightly less pronounced postfracture osteopenia. Calcitonin did not significantly influence the fracture healing but had a pronounced effect in preventing the osteopenia. The effects of 1.25(OH)2D3 are believed to be indirect, i.e., through the changes in the serum Ca X P product, whereas the osteopenia preventing action of calcitonin may come from direct effect on bone.

25-Hydroxycholecaliferol and fractures of the proximal.

Plasma 25-hydroxycholecalciferol (25-H.C.C.) has been measured in 67 consective cases of fracture of the proximal femur. The values found in these patients were not different from values found in these patients were not different from those in control groups at the same time of the year. Plasma 25-H.C.C. was not correlated to plasma calcium or phosphorus, the Ca times P product, or the alkaline phosphatase. X-rays showed Looser zones in only 1 patient, in whom the lowest plasma 25-H.C.C. was found. Osteomalacia is not uncommon among elderly people in Denmark, but it is more likely to depend on a decline in the renal efficiency to convert 25-H.C.C. to 1,25-dihydroxycholecalciferol than a low dietary intake of vitamin D.
