BACKGROUND Pregnancy causes a physiological increase in renal blood flow and glomerular filtration rate, which leads to a transient increase in urinary protein excretion. Up to 300 mg/d proteinuria is known to occur in pregnancy due to physiological changes. Proteinuria of greater than 3 g/d is categorized as being within the nephrotic range, and the most common cause of nephrotic range proteinuria in the later stages of pregnancy is preeclampsia. Minimal change disease (MCD) as a cause of nephrotic syndrome is rare in pregnancy and is rarer still after abortion. Here, we report a patient who presented with nephrotic syndrome due to MCD after elective surgical abortion. CASE REPORT A 21-year-old woman presented with shortness of breath, worsening anasarca, abdominal distension, and weight gain 3 weeks after undergoing elective surgical abortion at 7 weeks of gestation. There was no hematuria and no past medical history or family history of kidney disease. Investigations revealed normal serum creatinine with hypoalbuminemia, dyslipidemia, nephrotic range proteinuria, and negative serology for autoimmune diseases. Renal biopsy showed podocyte effacement with normal glomeruli and intact tubulointerstitium, confirming the diagnosis of MCD. The patient was treated with steroids, antidiuretics, statins, and angiotensin receptor blockers. She responded well, showing symptomatic improvement and resolution of proteinuria, hypoalbuminemia, and dyslipidemia. She was gradually tapered off steroids during subsequent follow-up visits. CONCLUSIONS Only a single case of a patient presenting with acute renal failure and MCD after a missed abortion has been reported. To the best of our knowledge, this is the second case report of MCD after abortion and the first report of a patient with MCD without acute renal failure after elective termination of pregnancy.
妊娠会导致肾血流量和肾小球滤过率生理性增加,从而使尿蛋白排泄出现短暂增加。已知由于生理变化,妊娠期间可出现高达300mg/d的蛋白尿。蛋白尿大于3g/d被归类为肾病范围,妊娠后期肾病范围蛋白尿最常见的原因是子痫前期。微小病变病(MCD)作为肾病综合征的病因在妊娠中罕见,流产后更为罕见。在此,我们报告一名患者,在选择性手术流产后因MCD出现肾病综合征。
一名21岁女性,在妊娠7周时接受选择性手术流产3周后,出现呼吸急促、全身性水肿加重、腹胀和体重增加。无血尿,既往无肾脏疾病病史或家族史。检查发现血清肌酐正常,但有低白蛋白血症、血脂异常、肾病范围蛋白尿,自身免疫性疾病血清学检查阴性。肾活检显示足细胞消失,肾小球正常,肾小管间质完整,确诊为MCD。患者接受了类固醇、利尿剂、他汀类药物和血管紧张素受体阻滞剂治疗。她反应良好,症状改善,蛋白尿、低白蛋白血症和血脂异常均得到缓解。在随后的随访中,她逐渐减少了类固醇用量。
仅有一例漏诊流产后出现急性肾衰竭和MCD的病例报告。据我们所知,这是流产后MCD的第二例病例报告,也是选择性终止妊娠后无急性肾衰竭的MCD患者的首例报告。
