摘要:

目的 探讨IgG4相关性肾病的临床表现、实验室及影像学特点、肾脏病理特征和治疗方案。方法 回顾性分析2016年3月至 2021年3月于广东省中医院珠海医院肾病科住院经肾穿刺活检确诊为IgG4 相关性肾病的患者4例,比较其临床表现、实验室及影像学特点、肾脏病理特征及治疗效果。结果 共纳入患者4例,其中男性3例,女性1例,中位年龄71岁;急性起病2例,慢性病程2例;病变累及肾脏和胰腺1例,病变累及肾脏和腹膜后1例;主要临床表现多样,无特异性;4例均出现血清肌酐升高伴少量蛋白尿,血清IgG4显著升高3例;4例均经肾脏病理诊断符合IgG4 相关性肾小管-间质肾炎;4例均接受糖皮质激素治疗,疗效明显。结论 IgG4相关性肾病临床罕见,易造成漏诊误诊,血清IgG4筛查有助于提高诊断率,肾穿刺活检是诊断的金标准,糖皮质激素治疗有效,随访效果较好。

Abstract:

Objective To explore the clinical manifestations, laboratory and imaging characteristics, pathological features of the kidney and treatment regimen for immunoglobulin G4 (IgG4)-related kidney disease (IgG4-RKD). Methods Four cases of IgG4-RKD diagnosed by renal biopsy in Department of Nephrology, Guangdong Provincial Hospital of Chinese Medicine, Zhuhai from March 2016 to March 2021 were retrospectively analyzed. Their clinical manifestations, laboratory and imaging characteristics, pathological features of the kidney and therapeutic outcome were compared. Results A total of 4 cases of IgG-RKD were included, involving three males and one female with the median age of 71 years. Two cases presented acute onset and two cases were chronic course. The injured organs of one case were kidney and pancreas and the other case was affected by the kidney and retroperitoneum. The main clinical manifestations were varied and unspecific. Four cases developed elevated serum creatinine with mild proteinuria. Three cases presented significantly increased serum IgG4. All patients were diagnosed with IgG4-related tubulointerstitial nephritis. Patients received glucocorticoid therapy with a significant therapeutic efficacy. Conclusion IgG4-RKD is rare and prone to missed diagnosis and misdiagnosis. Serum IgG4 screening can help to elevate the diagnosis rate. Renal biopsy is the gold standard for diagnosing IgG4-RKD. Glucocorticoid therapy is effective and obtains a favorable follow-up outcome.
