HLA-B27 and Ankylosing Spondylitis
Ankylosing spondylitis (AS) is a chronic inflammatory disease with potential disabling outcomes. Clinically, patients presented with inflammatory lower back pain, enthesis and alternated buttock pain (van der Linden & van der Heijde, 1998). Bernard Corner (16661698) was the first physician who published the clinical features of AS in his medical thesis (Baker & Weisman, 2006). In the late 19th ...
متن کاملASSOCIATION OF HLA-B27 WITH ANKYLOSING SPONDYLITIS IN ISFAHAN, IRAN
Using a standard microcytotoxicity (NIH) technique of tissue typing, the HLA-B27 antigen was identified in 30 out of 34 patients (HH.2%) with classical ankylosing spondylitis (AS), compared to 6 out of 70 controls (H.6%) (P < 0.005). We also found this antigen in 8 out of 76 (10.5%) patients with non-AS arthritis.

متن کاملAutoantibodies to HLA B27 in the sera of HLA B27 patients with ankylosing spondylitis and Reiter's syndrome. Molecular mimicry with Klebsiella pneumoniae as potential mechanism of autoimmune disease
Ankylosing spondylitis (AS) and Reiter's syndrome (RS) both show a strong correlation with the HLA B27 haplotype. We studied whether sharing of homologous amino acid sequences in the HLA B27 antigen with an invading microbe might occur, and if so, what is the biological significance of such homology. In a computer search of the Dayhoff data bank, we found a homology of six consecutive amino aci...
متن کاملHLA B27 and the genetics of ankylosing spondylitis.
One hundred and twenty-eight of 145 patients with ankylosing spondylitis (AS) were found to be HLA B27 positive. Five patients had evidence of a sero-negative peripheral arthritis resembling peripheral psoriatic arthritis and 3 of these were B27 negative. One further B27 negative patients had a sister with ankylosing spondylitis and ulcerative colitis and a mother with ulcerative colitis. There...
