Abstract

The syndrome associated with lack of growth hormone (GH) in adults can be reversed by treatment with recombinant human GH (rhGH) with apparently beneficial clinical effects. This syndrome is strikingly similar to the characteristics of normal older adults which are known as the somatopause. GH secretion and insulin-like growth factor I levels are reduced in healthy older people and it has been suggested that the somatopause is an age-related GH deficiency state.

This review describes the physiological control of GH secretion in adults and seeks an explanation for the age-related decline, considering the impact of other factors such as nutrition and mobility, and particularly whether exercise offers a physiological approach to changing both the GH decline and the somatopause. The benefits and side-effects of treatment with rhGH for normal older people or older patients facing catabolic stresses are reviewed together with alternative approaches to stimulate GH such as GH-releasing hormone and the new pharmaceutical GH secretagogues.

老年人的生长激素分泌:衰老与躯体暂停
与成人生长激素(GH)缺乏相关的综合征可以通过重组人生长激素(rhGH)治疗逆转,具有明显的有益临床效果。这种综合症与正常老年人的特征惊人地相似,也就是所谓的躯体停经。健康老年人的生长激素分泌和胰岛素样生长因子I水平降低,有人认为,生长暂停是一种与年龄相关的生长激素缺乏状态。这篇综述描述了成人生长激素分泌的生理控制,并寻求年龄相关下降的解释,考虑到营养和活动等其他因素的影响,特别是运动是否提供了一种改变生长激素下降和身体暂停的生理途径。对正常老年人或面临分解代谢压力的老年患者使用rhGH治疗的益处和副作用进行了综述,并介绍了刺激GH的替代方法,如GH释放激素和新型药物GH分泌剂。
