降钙素基因多肽对骨代谢的影响

根据骨质疏松的发病机制不同,可分为原发性骨质疏松和继发性骨质疏松,原发性骨质疏松又可分为绝经性骨质疏松和老年性骨质疏松。骨质疏松是由多种发病因素共同作用的结果,在各型骨质疏松中,降钙素均发挥重要的调节作用。近年研究发现某些神经、血管活性肽,如降钙素基因多肽(Calcitonin gene-related peptide,CGRP）,在结构和功能上与降钙素具有一定的相似性。本文将降钙素基因多肽对骨代谢影响的相关研究进展作以下综述。

Effects of salmon calcitonin suppositories on bone mass and turnover in established osteoporosis

The objective of this study was to test the efficacy and safety of salmon calcitonin (sCT) suppository in postmenopausal women with previous hip fractures as an inhibitory agent of bone loss. The study was a single blind, randomized, and placebo-controlled trial comparing three parallel groups of patients. Fifty-four healthy women were randomly allocated to 1 year's treatment with either sCT 100 IU/6 times a week, 200 IU/3 times a week, or placebo/6 times a week. All groups received a calcium supplement of 500 mg daily. Fifteen patients left the study before its end, six of those due to adverse events, such as abdominal and rectal pain, nausea, headache, and diarrhea. Bone mineral density of the spine and the femoral neck was measured every 26 weeks, and biochemical markers of bone turnover were measured at baseline and week 12, 26, and 52. There were no significant changes in bone mineral density in the spine and in the hip in any of the treatment groups. No significant changes were observed in serum alkaline phosphatase, serum osteocalcin, urine hydroxyproline, and urine pyridinoline or deoxypyridinoline. Conclusively, we did not observe any significant effect on bone metabolism in women with postmenopausal osteoporosis after 1 year of treatment with sCT suppositories at the doses used.     

Effects of salmon calcitonin on the bone loss induced by ovariectomy

Summary We present the results of a 12-month clinical study assessing the effects of synthetic salmon calcitonin (sCT) on a group of fertile white women who had undergone ovariectomy for uterine fibromatosis. The study was performed to verify whether CT can prevent the loss of bone mass and the changes in calcium-phosphorus metabolism associated with acute estrogen deficiency. The study consisted of an initial double-blind phase of 6 months, followed by a 6-month open period. Treated patients were given 100 MRC U of synthetic salmon CT injected i.m. in the morning, every other day, starting on the 7th day after the operation and continued for 12 months. Control patients received a placebo injection for the first 6 months; subsequently, they too were treated with sCT i.m. every other day for 6 months at the same dose as the 12 month-treated group. All patients received 500 mg of elementary calcium p.o., b.i.d. Bone mineral content (BMC) was measured at the extreme distal radius of the nondominant arm by a dual photon bone densitometer which utilizes two radio nuclides, 241 Am and 125 I, with energies of about 60 and 30 KeV. Biochemical parameters of the calcium-phosphorus metabolism were also measured. After 12 months of study, no significant changes of BMC were observed in the 12 months sCT treated group, while control patients, treated 6 months after the ovariectomy, showed a significant decrease in BMC values. Total hydroxyproline/ creatinine (OHPr/Cr) ratio, which increased after ovariectomy, returned to normal after the first month of sCT administration in the continuously treated group whereas it remained high in the control group up to the 6th month of observation, declining thereafter in coincidence with sCT treatment. The behavior of Bone GLA-protein (BGP), like that of the nondializable OHPr/Cr ratio, was substantially similar in both treated and control groups for the entire period of observation. These results show that prophylactic administration of salmon CT in ovariectomized women prevent estrogen deficiency-induced bone loss, inhibiting skeletal resorption and allowing osteogenesis to occur normally.     

强筋健骨胶囊联合鲑鱼降钙素治疗绝经后骨质疏松症短期疗效临床研究

目的探索强筋健骨胶囊联合鲑鱼降钙素治疗绝经后骨质疏松症短期疗效。方法 150例绝经后骨质疏松症患者随机分为治疗组(n=75)和对照组(n=75)。对照组给予鲑鱼降钙素治疗,治疗组给予强筋健骨胶囊联合鲑鱼降钙素治疗,为期3个月。检测治疗后两组患者数字疼痛评分(numerical rating scale,NRS)、视觉模拟疼痛评分(visual analogue scale,VAS)、Oswestry功能障碍指数(oswestry disability index,ODI)和JOA下腰功能评分(Japanese Orthopaedic Association Scores, JOA)改变,血清I型前胶原N端前肽(PINP)和血清I型胶原羧基末端肽(β-CTX)的水平改变;同时记录治疗有效率和药物不良反应。结果治疗前,两组骨代谢指标和NRS、VAS、ODI、JOA评分比较不具有统计学意义(P0.05)。治疗3个月后,两组NRS、VAS、ODI、JOA评分都有不同程度的改善,其中治疗组的上述评分改善更明显,和对照组比较有明显的统计学意义(P0.05);同时各组血清PINP和β-CTX水平均降低,而治疗组改变更明显,两组比较有明显的统计学意义(P0.05)。治疗组治疗有效率显著高于对照组,而药物不良反应比较无统计学意义(P0.05)。结论强筋健骨胶囊联合鲑鱼降钙素治疗绝经后骨质疏松症短期疗效显著。     

Acute effects of nasal salmon calcitonin on calcium and bone metabolism

Summary Effects of a single dose of 200 IU of nasal salmon calcitonin (SCT) on calcium metabolism and biochemical markers of bone turnover were investigated in 12 healthy male volunteers in a randomized, placebo-controlled, crossover design. The nasal spray was given in the morning, and subsequently blood and urine samples were collected for 26 hours. There was a significant decrease in serum ionized calcium with a nadir 4 hours after administration of nasal SCT accompanied by a significant increase in serum parathyroid hormone (P = 0.01) and serum calcitriol (P = 0.04). Nasal SCT did not reduce urinary hydroxyproline/creatinine. Urinary deoxypyridinoline/creatinine was lowered significantly 2 hours after administration of nasal SCT and throughout the first 24 hours, but remained unchanged for the last 2 hours. On a 24-hour basis, urinary deoxypyridinoline/creatinine decreased from 14.1 (3.5) nmol/mmol to 11.7 (3.2) nmol/mmol after nasal SCT (P = 0.04). Nasal SCT did not change the serum levels of alkaline phosphatase, osteocalcin, and the carboxyterminal propeptide of type 1 procollagen. The results indicate that nasal SCT given as a single dose provokes a modest decrease in bone resorption lasting several hours, but leaves bone formation unaffected.
