To identify the clinical and histopathological characteristics of patients who develop acute interstitial nephritis (AIN) following snake envenomation.
A retrospective analysis of patients diagnosed with snake envenomation-induced AIN from October 2013 to November 2014.
After snake envenomation, 88 patients developed acute kidney injury (AKI). Biopsies were performed on 7 patients due to nonrecovery of kidney function. Among these, 5 patients had AIN. Thus, AIN accounted for 5.7% of snakebite-related acute kidney injury. All patients had severe envenomation at presentation and had prolonged renal failure. Kidney biopsy found a mixed infiltrate composed of predominantly lymphocytes, with variable proportions of other cells including eosinophils neutrophils and plasma cells. The response rate to corticosteroids was 80%.
AIN after snake bite is not uncommon. AIN needs to be considered in patients with persistent renal failure after snake envenomation. Identifying this complication is of utmost importance because of the potentially reversible nature.
确定蛇咬伤后发生急性间质性肾炎(AIN)患者的临床和组织病理学特征。
对2013年10月至2014年11月诊断为蛇咬伤所致AIN的患者进行回顾性分析。
蛇咬伤后,88例患者发生急性肾损伤(AKI)。因肾功能未恢复,对7例患者进行了活检。其中,5例患者患有AIN。因此,AIN占蛇咬伤相关急性肾损伤的5.7%。所有患者就诊时均有严重中毒,且肾衰竭持续时间长。肾活检发现以淋巴细胞为主的混合浸润,伴有不同比例的其他细胞,包括嗜酸性粒细胞、中性粒细胞和浆细胞。对皮质类固醇的反应率为80%。
蛇咬伤后发生AIN并不罕见。蛇咬伤后持续肾衰竭的患者需要考虑AIN。由于其潜在的可逆性,识别这种并发症至关重要。
