JCEM:帕瑞肽或成为生长抑素和培维索孟治疗肢端肥大的替代选择

2017-11-16 MedSci MedSci原创

大家都知道生长抑素和生长激素受体拮抗剂培维索孟是目前肢端肥大主要的药物治疗方式。2017年11月15日在JCEM上发表了一篇文章,旨在评估帕瑞肽长效缓释(PAS-LAR)单独或联合培维索孟的安全性和有效性,从而使通过生长抑素类似物(LA-SSAs)和培维索孟控制良好的肢端肥大患者转向PAS-LAR单独或联合培维索孟的治疗

大家都知道生长抑素和生长激素受体拮抗剂培维索孟是目前肢端肥大主要的药物治疗方式。2017年11月15日在JCEM上发表了一篇文章,旨在评估帕瑞肽长效缓释(PAS-LAR)单独或联合培维索孟的安全性和有效性,从而使通过生长抑素类似物(LA-SSAs)和培维索孟控制良好的肢端肥大患者转向PAS-LAR单独或联合培维索孟的治疗。

该前瞻性开放性研究共纳入61例肢端肥大患者,纳入要求为在LA-SSAs和培维索孟治疗期间,IGF-I≤1.2x正常值上限(ULN)。在基线水平,培维索孟的剂量直至12周时减少50%。当12周后IGF-I≤1.2xULN,患者改成PAS-LAR60mg单药治疗。当IGF-I>1.2xULN时,患者改成PAS-LAR60mg联合已减少一半的培维索孟剂量。

研究结果显示在基线水平,平均IGF-I为0.97xULN,而培维索孟的中位剂量为80mg/周。在12周时,IGF-I平均上升至1.59xULN,而IGF-I水平≤1.2ULN仅有24.6%的患者。在24周时,73.8%的患者IGF-I水平降至参考值。在基线和24周时,培维索孟的剂量减少了66.1%。PAS-LAR耐受性良好,但高血糖是最常见的不良反应。在24周时,糖尿病的发病率从基线32.8%上升至68.9%。

又上述研究可见改成PAS-LAR治疗,无论是单药还是联合培维索孟,可以控制大多数患者的IGF-I水平。PAS-LAR与LA-SSAs相比,显示出培维索孟节约效应66%。然而,高血糖却成为了最重要的安全问题,也为进一步研究指明了方向。

New Engl J Med:患巨人症和肢端肥大是因为基因突变?

生长是由一系列激素经过复杂的调控程序而导致的,这些激素来源于下丘脑,垂体和外周组织。遗传性疾病会引起生长激素分泌增加,导致肢端肥大。如果在骨骺闭合之前生长激素过度分泌,就会引起儿童型巨人症。非综合征型巨人症是由腺垂体的分泌紊乱所导致的,通常表现为家族性孤立垂体腺瘤或偶发垂体腺瘤。目前生长激素所导致的儿童巨人症和成人指端肥大的发病率正在上升,但是对于巨人症和肢端肥大症遗传学基础的认识还不够充分。为了
