    • 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). Also provided is a method of diagnosing a clinical subtype of Crohn's disease in a patient with CD by determining 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 a clinical subtype of Crohn's disease in a patient with CD by determining the presence or absence of ANCA, pANCA, SAPPA and anti-Saccharomyces cerevisiae antibodies (ASCA) in the patient with CD, where the presence 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 clinical subtype of CD lacking features of ulcerative colitis and having perforating or fistulizing disease or small bowel obstructive disease. Kits for diagnosing a clinical subtype 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)。 还提供了通过确定患有CD的患者中是否存在pANCA或斑点抗泛多晶核抗体(SAPPA)来诊断患有CD的克罗恩病的临床亚型的方法,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,SAPPA和抗Saccharomyces cerevisiae抗体(ASCA)的存在或不存在来诊断患有CD的克罗恩病的临床亚型的方法,其中 与无ASCA相结合表明具有UC特征的CD的临床亚型,SAPPA的存在表明CD具有穿孔或瘘阻碍性疾病或小肠阻塞性疾病的临床亚型,并且ASCA的存在与不存在ANCA 表示缺乏溃疡性结肠炎特征的CD的临床亚型,具有穿孔或瘘管疾病或小肠阻塞性疾病。 还提供了用于诊断克罗恩病临床亚型的试剂盒,其中含有嗜中性粒细胞和ASCA特异性抗原。
