Antiglomerular basement membrane (anti-GBM) antibodies are more often accompanied by myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) than by proteinase 3 antineutrophil cytoplasmic antibody (PR3-ANCA). Both disease processes can affect the kidneys and/or the lungs. Patients with dual positive disease may have an atypical presentation which may delay diagnosis and treatment. Here we report a case of crescentic glomerulonephritis associated with positive PR3-ANCA and anti-GBM antibodies who underwent both lung and kidney biopsies.
抗肾小球基底膜(anti-GBM)抗体更常伴有髓过氧化物酶抗中性粒细胞胞浆抗体(MPO-ANCA),而非蛋白酶3抗中性粒细胞胞浆抗体(PR3-ANCA)。这两种疾病过程均可影响肾脏和/或肺部。双阳性疾病患者可能有非典型表现,这可能会延迟诊断和治疗。在此,我们报告一例新月体性肾小球肾炎患者,其PR3-ANCA和抗GBM抗体均呈阳性,并接受了肺和肾活检。
