Infective endocarditis (IE) and small-vessel vasculitis may have similar clinical features, including glomerulonephritis. Furthermore the association between IE and ANCA positivity is well documented, making differential diagnosis between IE- and ANCA-associated vasculitis particularly difficult, especially in case of culture-negative IE. We report on one patient with glomerulonephritis secondary to culture-negative IE caused by Bartonella henselae which illustrates this diagnostic difficulty.
感染性心内膜炎（IE）和小血管血管炎可能具有相似的临床特征，包括肾小球肾炎。此外，IE与抗中性粒细胞胞浆抗体（ANCA）阳性之间的关联已有充分记录，这使得IE相关性血管炎和ANCA相关性血管炎的鉴别诊断尤为困难，尤其是在血培养阴性的IE病例中。我们报告了1例由汉赛巴尔通体引起的血培养阴性IE继发肾小球肾炎的患者，该病例说明了这种诊断困难。
