Résumé
Objective To investigate clinical significance of diagnosis of the anti saccharomyces cerevisiae antibody (ASCA), pancreatic acini antibody (PAB)resistance,resistance to small goblet cell antibody (GAB),anti neutrophil cytoplasm anti-bodies (ANCA)for inflammatory bowel disease (IBD)and the differential diagnosis of ulcerative colitis (UC)and crohn's disease (CD).Methods Collected 200 cases of test group sets of inflammatory bowel disease,serum by indirect immunofluo-rescence (IF).Results In the serum of 200 patients,106 cases with positive or weakly positive.Among them,the positive ASCA/weak positive 24 cases,14 cases of PAB,GAB 63 cases,28 cases ANCA,and included in ASCA group respectively and PAB group,GAB group,ANCA group.Positive rate of ANCA and GAB in the diagnosis of UC were 34% and 58%. Positive rate of ASCA and PAB in the diagnosis of CD were 28.6% and 38.1%.ANCA associated with GAB detection in the diagnosis of UC specific degree was 60%,ASCA associated with PAB detection in the diagnosis of CD specific degree was 75%.Conclusion Serum inflammatory bowel disease antibody spectrum in ASCA,ANCA,GBA and PAB four antibod-ies of joint detection has important guiding value to the diagnosis of IBD,also can be used as one of UC and CD in the differ-ential diagnosis methods.
