摘要:
A novel association between IBD and a polymorphism at amino acid residue 241 of ICAM-1 has been discovered. In accordance with the present invention there is provided methods of screening for IBD, methods for treating IBD, antibodies specifically reactive with ICAM-1 encoded by, R241 allele and kits which exploit the inventive methods.
摘要:
The invention provides a method of diagnosing or predicting susceptibility to a clinical subtype of Crohn's disease in a subject having Crohn's disease by determining the presence or absence of IgA anti-I2 antibodies in the subject, where the presence of the IgA anti-I2 antibodies indicates that the subject has a clinical subtype of Crohn's disease. In one embodiment, a method of the invention is practiced by further determining the presence or absence in the subject of a NOD2 variant, anti-Saccharomyces cerevisiae antibodies (ASCA), IgA anti-OmpC antibodies, or perinuclear anti-neutrophil cytoplasmic antibodies (pANCA). The methods of the invention can be used to diagnose or predict susceptibility to a clinical subtype of Crohn's disease, for example, a fibrostenotic subtype, a subtype characterized by the need for small bowel surgery, or a subtype characterized by the absence of features of ulcerative colitis.

摘要:
A novel association between certain tumor necrosis factor microsatellite alleles and Crohn's disease has been discovered. In accordance with the present invention, there is provided methods for screening for Crohn's disease comprising detecting the presence or absence of nucleic acid of a subject encoding TNF microsatellite alleles associated with Crohn's disease, wherein the presence of nucleic acid encoding three or more of the alleles is indicative of Crohn's disease. Kits useful for screening for Crohn's disease are also provided which comprise nucleic acid encoding TNF microsatellite alleles associated with Crohn's disease.
摘要:
The present invention provides a method of diagnosing a clinical subtype of Crohn's disease (CD) by determining whether perinuclear anti-neutrophil antibodies (pANCA) are present in a patient with CD, where the presence of pANCA indicates the clinical subtype of CD with features of ulcerative colitis (UC). The invention also provides a method of diagnosing a clinical subtype of CD by detecting an Arg.sup.241 allele at an ICAM-1 locus in a patient with CD, where the Arg.sup.241 allele indicates a clinical subtype of CD with features of ulcerative colitis. In addition, the invention provides a method of diagnosing a pANCA-positive subtype of CD by detecting an Arg.sup.241 allele at an ICAM-1 locus in a patient with CD, where the Arg.sup.241 allele indicates the pANCA-positive subtype of CD.
摘要:
The present invention relates to methods of prognosing inflammatory bowel disease (IBD) in an individual by determining the presence of at least one risk genetic variant and/or at least one risk serological marker. In one embodiment, the presence of risk serological marker ANCA is indicative of an aggressive form of ulcerative colitis. In another embodiment, the present invention relates to methods of diagnosing a Crohn's disease subtype in an individual, where the presence of risk variants and serological markers I2, OmpC and/or Cbir1 are indicative of the Crohn's disease subtype.
摘要:
The present invention relates to prognosing, diagnosing and treating of Crohn's disease. The invention also provides prognosis, diagnosis, and treatment that are based upon the presence of one or more genetic risk factors at the FUT2 genetic locus.
摘要:
This invention provides methods of diagnosing or predicting susceptibility to Crohn's Disease by determining the presence or absence of genetic variants. In one embodiment, the present invention provides methods to diagnose and/or predict susceptibility to Crohn's Disease in an individual by determining the presence or absence of anti-Cbir1 reactivity and the presence or absence of TLR5 risk variants. In another embodiment, the present invention provides methods to diagnose Crohn's Disease by determining the presence or absence of NFKB1 haplotype H3 and/or ASCA expression. In another embodiment, the present invention provides methods of diagnosing Crohn's Disease by determining the presence or absence of Cbir1 specific peripheral blood T cell proliferation.
摘要:
The present invention relates to prognosing, diagnosing and treating an aggressive form of Crohn's disease characterized by rapid progression to complication and/or surgery from the time of diagnosis. In one embodiment, the prognosis, diagnosis and treatment is based upon the presence of one or more genetic risk factors.
摘要:
This invention provides methods of diagnosis and treatment of inflammatory bowel disease. In one embodiment, the invention provides methods of diagnosing and/or predicting susceptibility for inflammatory bowel disease in the Puerto Rican population by determining the presence or absence of a risk variant at the HPS1 locus. In another embodiment, the invention further provides methods of diagnosing and/or predicting protection against inflammatory bowel disease by determining the presence or absence of a protective variant at the IRF1 locus. In another embodiment, the presence in an individual of a risk variant at the CARD8 locus is diagnostic of susceptibility to Crohn's Disease in a Puerto Rican individual. In another embodiment, the presence of a risk variant at the TLR-9 locus in an individual is diagnostic of susceptibility to Crohn's Disease.
