摘要 目的观察甲状腺功能低下患者不同病程血清Ghrelin的变化,探讨影响其变化的因素。方法对未经治疗的甲状腺功能减低患儿(甲低组23例)及非肥胖非甲状腺疾病的健康体检儿童(正常组30例)分别采血测定FT3、FT4、TSH及甲状腺抗体,并采用ELSIA方法测定血清Ghrelin水平。甲低组给予左甲状腺素钠治疗,治疗1个月和甲状腺功能正常后分别抽血测定FT3、FT4、TSH、Ghrelin水平,比较患儿治疗前后血FT3、FT4、TSH、Ghrelin水平的变化。结果甲低组患儿血清Ghrelin水平明显高于正常对照组(P〈0.01)。与治疗前比较,甲低组患儿血清Ghrelin水平较治疗前降低;治疗缓解后,甲低组血清Ghrelin水平与正常对照组比较差异无统计学意义(P〉0.05)。甲低患儿血清Ghrelin水平与FT4呈负相关(r=-0.23,P〈0.05),与性别、年龄、BMI、FT3及TSH无相关(P〉0.05)。结论Ghrelin水平可作为反映甲状腺功能低下的敏感指标,对患儿的甲状腺功能变化和病情转归具有指导意义。
