病例三,是妊娠早期患者,该患者有妊娠剧吐,TRAb结果正常,因此考虑患者亚临床甲亢与妊娠早期HCG升高相关,因此未选择药物治疗,而是随访观察,该患者随着妊娠周数的增加,到妊娠中期,TSH逐渐升高至正常范围。
总 结
SHyper病例在临床中并不少见,但经常因为患者无明显症状而被忽略。已有报道[7],SHyper患者易患骨质疏松和房性心律失常 ,尤其绝经后妇女患病率更高。限制碘摄入可使SHyper转化为持续甲亢发生率降低,同时骨质疏松和房性心律失常会减轻。
SHyper进展为甲亢所需的时间及在此期间主要影响因素的作用方式和作用强度,还需要大量临床数据研究证实。有些SHyper患者由于未及时复诊最终演变为显性甲亢或由于诱发心血管疾病后被诊断和治疗,有些SHyper疾病转归也可能正常呈自限性,早期治疗风险可能弊大于利。因此SHyper的诊治需要结合患者年龄,临床症状,合并疾病风险因素,相关辅助检查结果,综合分析药物治疗的利弊决定用药时机。
