9、献,总结该病特点。结果 该病主要表现为严重低钾血症、多处骨关节疼痛,易误诊。予积极补钾、抗醛固酮、抗骨质疏松治疗,有效缓解了病情。结论 GS虽然尿钙低,无低血镁,但也可以合并骨质疏松。因此,对存在多关节疼痛的GS病人,应及时进行双能X线骨密度检查早期筛查骨质疏松。对于此类病人,积极给予补钾、抗醛固酮及抗骨质疏松治疗可提高疗效。关键词:Gitelman综合征;低钾血症;骨质疏松;镁Gitelman syndrome with osteoporosis and normal blood magnesium:one case reportCHEN Zongcun,LAI Shuchang,WANG

15、1-2。既往文献很少报道该病合并骨质疏松症。海南医学院第二附属医院收治1例合并骨质疏松且血镁正常的GS病人,经补钾、抗骨质疏松等治疗,病情好转。本研究探讨了该例病人的临床特点和诊疗方法。1临床资料男性,26岁,因“反复四肢乏力14年,骨痛3年”于2017年2月在海南医学院第二附属医院内分泌科住院。病人14年前出现四肢酸痛、乏力,无怕热、多汗,在当地医院查血钾偏低,诊断“低钾血症”,经补钾治疗后症状缓解。出院后病人上述症状间断发作,约每 12年 1次,自行服用钾剂后症状可缓解。近3年上述症状较频繁,每 34 月 1 次,较前加重,渐有四肢、胸肋部、腰背部及髋关节疼痛,行走困难,伴排尿增多(约10
16、次/日)。先后多次在多家医院就诊,均诊断“低钾血症”,经补钾治疗症状缓解。1 d前病人上述症状再次出现,查血钾1.75 mmol/L,予补钾治疗但症状未缓解。有肾结石两年余,未手术治疗。家族中无类似病史者。入院查体:体温37.0,脉搏94次/分,呼吸20次/分,血压 109/70 mmHg,身高 160 cm,体质量 36 kg,身体质量指数14.1 kg/m2。发育正常,营养欠佳,体形消瘦。神志清。行走不便,步态呈外八字,下蹲后起身困难。甲状腺无肿大,质软,无压痛,未扪及结节,未闻及血管杂音。心肺腹查体无明显异常。双上肢肌力级,双下肢肌力级,四肢肌张力正常。双膝腱及跟腱反射存在。Babinski征阴性。辅助检查:血气分析:pH 7.4,实际碳酸氢盐22.1 mmol/L,二氧化碳分压 37.4 mmHg。生化:钾2.03 mmol/L,钠130.1 mmol/L,氯95.0 mmol/L,钙2.1 mmol/L,磷 0.5 mmol/L,镁 1.1 mmol/L,肌 酐 104 mol/L,ALP 237 U/L。尿沉渣:pH 8.0。24 h 尿钾125.5 mmol/L。24 h
