Increased HLA A1 and diminished HLA A3 in lymphocytic colitis compared to controls and patients with collagenous colitis 总被引:3,自引:0,他引:3
Dr. Francis M. Giardiello MD Audrey J. Lazenby MD John H. Yardley MD Wilma B. Bias PhD James Johnson MD Robert G. Alianiello BS Marshall S. Bedine MD Theodore M. Bayless MD 《Digestive diseases and sciences》1992,37(4):496-499
Lymphocytic colitis is a newly described chronic diarrheal disorder. Although its etiology is unknown, the possibility has been raised that autoimmunity may play a role in both lymphocytic and collagenous colitis, a similar clinicopathologic illness. The frequencies of HLA class I and class II antigens were examined in 24 white patients with lymphocytic colitis and in 47 white patients with collagenous colitis. Frequencies in these two disorders were compared to control white populations and to each other. An increased frequency of HLA-A1 was noted in 16 of 24 lymphocytic colitis patients (66.6%) compared with 1089 of 3942 controls (27.6%) (P<0.005; relative risk 5.2). Furthermore, HLA-A3 was found in decreased frequency in lymphocytic colitis patients: 0 of 24 (0%) compared with 1017 of 3942 controls (25.8%) (P<0.05; relative risk 0.0). Collagenous colitis patients had no significant deviation from control frequencies of HLA antigens. In lymphocytic colitis, there was no significant increase in B8 or DR3 antigens, which are found in linkage disequilibrium with A1 and associated with many autoimmune diseases. Moreover, the frequency of autoimmune-associated class I HLA antigens was not increased in lymphocytic colitis. Statistically significant differences existed between lymphocytic and collagenous colitis in HLA-A1, A3, Bw6, and B7 antigen frequencies. The HLA patterns noted previously in other gastrointestinal disorders, including ulcerative colitis and Crohn's disease, were not apparent in lymphocytic or collagenous colitis. HLA typing provides further evidence that lymphocytic colitis is a distinct form of chronic intestinal inflammatory disease associated with HLA class I phenotypes.Presented in part at the American Gastroenterological Association in May 1988 and published with preliminary data in a previous article (reference 1).Supported in part by The National Foundation for Ileitis and Colitis, by an institutional grant from The Johns Hopkins School of Medicine, and by outpatient GCRC grant RR00722. 相似文献
