【摘要】 目的 探讨Gitelman综合征的临床特点，评价血镁在鉴别Gitelman综合征和Bartter综合征中的价值。方法 回顾性分析河北医科大学第二医院内分泌科收治的1例正常血镁的Gitelman综合征患者的临床表现、诊疗过程及结局，并进行相关文献复习。结果 患者临床表现为低钾血症、代谢性碱中毒、正常血镁、低血压及肾素-血管紧张素-醛固酮系统活化，经基因检测明确Gitelman综合征的诊断。结论 Gitelman综合征表型存在异质性，基因型-表型研究尚不完善。以低镁血症区分Gitelman综合征和Bartter综合征是不严谨的，应进一步行基因检测明确诊断。更多还原

【Abstract】 Objective To investigate the clinical characteristics of Gitelman syndrome and evaluate the differential value of blood magnesium in Gitelman syndrome and Bartter syndrome. Methods A case of Gitelman syndrome with normomagnesemia admitted to the Department of Endocrinology of the Second Hospital of Hebei Medical University was retrospectively analyzed for its clinical manifestations, diagnosis and treatment process and treatment outcome, and the relevant literature was reviewed. Results The patient presented with hypokalemia, metabolic alkalosis, normomagnesemia, hypotension and the activation of the renin-angiotensin-aldosterone system. The diagnosis of Gitelman syndrome was confirmed by genetic testing.Conclusion The phenotype of Gitelman syndrome is heterogeneous, and the genotype-phenotype studies are not perfect. Therefore, it is not rigorous to use hypomagnemia as the criterion to distinguish Gitelman syndrome from Bartter syndrome in the suspected clinical diagnosis. Further genetic testing should be performed to confirm the diagnosis.更多还原
