摘 要:目的:重组人甲状旁腺激素(rhPTH)(1-34)是目前唯一促进骨形成的药物,中国绝经后骨质疏松症(PMOP)妇女长期应用 rhPTH(1-34)的有效性和安全性尚未见报道,本研究首次为期18个月,全国11个城市探讨比较 rhPTH(1-34)与依降钙素(益盖宁,CT)治疗 PMOP 的有效性和安全性。方法选择453例 PMOP 患者随机分至每日1次 rhPTH(1-34)20μg(200 U),治疗18个月组(n =341)或每周一次 CT 20U,治疗12个月组(n=112)。治疗前、后6、12、18个月检测腰椎(L1-4)和股骨颈骨密度及骨转换生化指标:分别用放免法测定血清骨特异碱性磷酸酶(BSAP)定量夹心酶联免疫法测尿 C 端肽(CTX)/肌酐,评估统计骨痛及骨折发生率和药物不良反应。结果治疗后6、12、18个月 rhPTH(1-34)组较 CT 组腰椎骨密度显著增加(4.3%对1.94%,6.8%对2.72%,9.51%对2.86%,P<0.01)。股骨颈骨密度,rhPTH(1-34)组较CT 组在治疗12个月有上升趋势,18个月增长具有统计学意义(2.64%,P<0.01)。骨形成指标在6、12、18个月,rhPTH(1-34)组均较 CT 组有明显增长:血清 BSAP 93.67%对-3.56%,117.78%对-4.12%,49.24%对-5.81%,P<0.01;骨吸收指标尿 C 端肽/肌酐250%对-29.5%,330%对-41.4%,273%对-10.6%,P<0.01。rhPTH(1-34)与 CT 组在止痛作用相似。 rhPTH(1-34)组临床骨折率为3.23%(11/341),CT 组骨折率为5.36%(6/112,P=0.303)。两种治疗均耐受良好。 rhPTH(1-34)组高钙尿症(9.38%)和高钙血症(7.04%)均为一过性,没有导致临床症状发生。 rhPTH(1-34)组注射部位皮肤瘙痒(8.21%对2.68,P =0.044)和发红(4.40%对 0,P=0.024)发生率高。 CT 组恶心/呕吐(16.07%对 6.16%,P=0.001)和颜面潮红(7.14%对 0.59%,P<0.001)更为常见。结论 rhPTH(1-34)可更明显增加腰椎骨密度和骨形成指标。经过18个月治疗,也能增加股骨颈骨密度,降低各部位的骨折发生率,可以有效地改善骨�Objective Recombinant human parathyroid hormone(1-34) [ rhPTH(1-34)] is the unique anabolic substance acting on the skeleton. The efficacy and safety of long-term administration of rhPTH(1-34) in Chinese postmenopausal women have not been evaluated. 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 A total of453 postmenopausal women with osteoporosis were enrolled in an 18-month, multi-center, randomized, controlled study. They were randomized to receive either rhPTH(1-34) 20 μg(200 U) daily for 18 months, or elcatonin 20 U weekly for 12 months. Lumbar spine ( L1-4) and femoral neck bone mineral density (BMD), fracture rate, back pain as well as biochemical markers of bone turnover ( serum bone-specific alkaline phosphatase was measured by radioimmunoassay; C-telopeptide/ creatinine ( CTX/ Cr) measured by quantitative sandwich enzyme-linked immunosorbent assay) at 6, 12, and 18 months. Adverse events were recorded. Results rhPTH(1-34) increased lumbar BMD more significantly than that did by elcatonin at 6 months( M6), 12 months (M12), and 18 months(M18; 4. 3% vs 1. 94% , 6. 8% vs 2. 72% , 9. 51% vs 2. 86% , P〈0. 01). There was only a small but significant increase of femoral neck BMD at M18(2. 64% , P〈0. 01) in rhPTH(1-34) groups. There were greater increases in bone turnover markers in the rhPTH(1-34) group than in the elcatonin group at M6, M12, and M18[serum bone-specific alkaline phosphatase(BSAP) 93. 67% vs -3. 56% , 117. 78% vs -4. 12% , 49. 24% vs-5. 81% , P〈0. 01; urinary CTX/ Cr 250% vs -29. 5% , 330% vs -41. 4% , 273 % vs -10. 6% , P〈0. 01]. rhPTH (1-34) showed similar effect of pain relief as elcatonin. The incidence of clinical fractures was 5. 36% (6 / 112) in elcatonin group and 3. 23% ( 11 / 341 ) in rhPTH ( 1-34 ) group ( P = 0. 303 ). Both treatments were well tolerat
