Abstract

Objective

Anorexia nervosa (AN) is a severe mental disorder that is characterized by restriction of energy intake, low weight, and endocrine abnormalities. One of the known endocrine changes in relation to underweight is in the GH/IGF-I axis. The aim of the study was (a) to investigate longitudinal characteristics of the IGF-I-change during therapy and weight gain in adult AN, (b) to determine relationships between IGF-I and leptin, (c) to characterize patients with weak and pronounced hormonal reactions to underweight.

Design

Data was assessed from 19 AN patients. Over the first two months, serum IGF-I concentrations were assessed on a weekly basis; thereafter on a monthly basis. The trend of IGF-I values over time was analyzed using individual growth models.

Results

In total, n = 177 IGF-I measurements were analyzed. IGF-I increased significantly dependent on BMI (slope = 20.81, p < 0.001), not modulated by duration of disease. The increase in IGF-I was significantly related to the increase in leptin concentrations over time (slope = 15.57, p < 0.001). Patients with a weaker hormonal reaction to underweight were significantly older compared to patients with a pronounced hormonal reaction (t(17) = 3.07, p = 0.007).

Conclusions

During treatment, IGF-I change is clearly related to BMI as well as to leptin. Age appears to be associated with the IGF-I response to underweight.

神经性厌食症住院患者血清IGF-1反应类型及与BMI、瘦素的关系

目的神经性厌食症(anorexia neurosa, AN)是一种以能量摄入受限、体重低、内分泌异常为特征的严重精神障碍。已知的与体重不足有关的内分泌变化之一是GH/IGF-I轴。该研究的目的是(a)调查成人AN治疗期间IGF-I变化和体重增加的纵向特征，(b)确定IGF-I和瘦素之间的关系，(c)表征对体重不足的弱而明显的激素反应的患者。DesignData从19例AN患者中进行评估。在前两个月，每周评估血清igf - 1浓度;此后按月收费。使用个体生长模型分析了IGF-I值随时间的变化趋势。结果共分析n = 177例IGF-I检测结果。IGF-I随BMI显著升高(斜率= 20.81,p <0.001)，不受疾病持续时间的影响。随着时间的推移，IGF-I的增加与瘦素浓度的增加显著相关(斜率= 15.57,p <0.001)。与激素反应明显的患者相比，激素反应较弱的患者年龄明显偏大(t(17) = 3.07, p = 0.007)。结论在治疗过程中，igf - 1的变化与BMI和瘦素有明显的相关性。年龄似乎与igf - 1对体重过轻的反应有关。

期刊介绍： Growth Hormone & IGF Research is a forum for research on the regulation of growth and metabolism in humans, animals, tissues and cells. It publishes articles on all aspects of growth-promoting and growth-inhibiting hormones and factors, with particular emphasis on insulin-like growth factors (IGFs) and growth hormone. This reflects the increasing importance of growth hormone and IGFs in clinical medicine and in the treatment of diseases.
