摘要

感染性心内膜炎可引起肾脏并发症,其中之一就是肾小球肾炎。肾活检通常会发现免疫复合物或补体介导的肾小球肾炎。在一小部分病例中,可能会出现弱免疫性肾小球肾炎。大多数情况下,这类患者会在血清学检测中发现抗中性粒细胞胞浆抗体(ANCA)。越来越多关于巴顿氏菌心内膜炎导致 ANCA 相关性肾小球肾炎病例的报道。这种类型的心内膜炎会给诊断带来困难,因为这些患者通常培养阴性。在此,我们报告了一例ANCA阴性的贫免疫性肾小球肾炎病例,该病例的活检结果显示与巴顿氏菌心内膜炎相关的花斑新月体。

ANCA-Negative Pauci-Immune Glomerulonephritis Associated with Bartonella Endocarditis.

Kidney complications can occur due to infective endocarditis, one of which is glomerulonephritis. Most often, an immune complex or complement-mediated glomerulonephritis is seen on kidney biopsy. In a minor subset of cases, pauci-immune glomerulonephritis may be present. Most often, such patients will demonstrate the presence of antineutrophil cytoplasmic antibodies (ANCA) on serologic testing. A growing number of cases of ANCA-associated glomerulonephritis due to Bartonella endocarditis have been reported. This type of endocarditis can present diagnostic difficulties given that these patients are often culture negative. Herein, we report a challenging case of ANCA-negative pauci-immune glomerulonephritis showing florid crescents on biopsy that was associated with Bartonella endocarditis.
