    • Provided herein is a method of diagnosing a clinical subtype of Crohn's disease (CD) by determining whether perinuclear anti-neutrophil antibody (pANCA) is present in a patient with CD, where the presence of pANCA indicates a clinical subtype of CD with features of ulcerative colitis (UC). The present also provides a method of diagnosing clinical subtypes of Crohn's disease in a patient with CD by determing whether pANCA or speckling anti-pan polymorphonuclear antibody (SAPPA) is present in the patient with CD, where the presence of pANCA indicates a clinical subtype of CD with features of ulcerative colitis and where the presence of SAPPA indicates a clinical subtype of CD having perforating, fistulizing or small bowel obstructive disease. The invention further provides a method of diagnosing clinical subtypes of Crohn's disease in a patient with CD by determining the presence or absence of ANCA, pANCA and SAPPA in the patient with CD and determining the presence or absence of anti-Saccharomyces cerevisiae antibodies (ASCA) in the patient with CD, where the presnece of pANCA combined with the absence of ASCA indicate a clinical subtype of CD with features of UC, the presence of SAPPA indicates a clinical subtype of CD having perforating or fistulizing disease or small bowel obstructive disease, and the presence of ASCA combined with the absence of ANCA indicates a clincial subtype of CD lacking features of ulcerative colitis and having perforating or fistulizing disease or small bowel obstructive disease. Kits for diagnosing clinical subtypes of Crohn's disease, which contain neutrophil and antigen specific for ASCA, also are provided.
    • 本文提供了通过确定是否存在CD患者中存在核周抗中性粒细胞抗体(pANCA)来诊断克罗恩病(CD)的临床亚型的方法,其中pANCA的存在表示具有溃疡特征的CD的临床亚型 结肠炎(UC)。 本发明还提供了一种诊断患有CD的克罗恩病的临床亚型的方法,其通过确定患有CD的患者是否存在pANCA或斑点性抗泛多形核抗体(SAPPA),其中pANCA的存在表示临床亚型 CD具有溃疡性结肠炎的特征,并且其中SAPPA的存在表示具有穿孔,瘘管或小肠阻塞性疾病的CD的临床亚型。 本发明还提供了一种通过在CD患者中确定ANCA,pANCA和SAPPA的存在或不存在来确定患有CD的患者中克罗恩病的临床亚型的方法,并确定抗酿酒酵母抗体(ASCA)的存在或不存在, 在患有CD的患者中,其中pANCA的预后与不存在ASCA指示具有UC特征的CD的临床亚型,SAPPA的存在表示CD具有穿孔或瘘症或小肠阻塞性疾病的临床亚型,以及 ASCA的存在与无ANCA的存在表明CD的临床亚型缺乏溃疡性结肠炎的特征,并且具有穿孔或瘘管疾病或小肠阻塞性疾病。 还提供了用于诊断包含嗜中性粒细胞和ASCA特异性抗原的克罗恩病的临床亚型的试剂盒。
