Complement activation and HLA-B27.
The efficiency of complement activation was studied in sera from HLA-B27 positive and negative subjects (27 with previous yersinia arthritis and 35 controls). Activation of complement with zymosan induced higher mean levels of the anaphylatoxin C3a in HLA-B27 positive sera (mean (SD) 7.40 (1.66) mg/l) than in HLA-B27 negative sera (6.41 (1.79) mg/l). Similarly, higher levels of C3d,g, another C...
متن کاملHLA-B27: what's new?
The HLA-B27 molecule is one of the most fascinating in medicine. Its contribution to the aetiopathogenesis of SpA and other diseases, and its protective action in certain infections, continue to challenge our understanding of its immunobiology and physiological roles. Animal studies have helped to cast light on ways in which HLA-B27 exerts its effects. Subtle variations in structure and behavio...
متن کاملHLA-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 کاملSeasonal variation of acute anterior uveitis: differences between HLA-B27 positive and HLA-B27 negative disease.
One hundred and seventy-five consecutive patients with acute anterior uveitis (AAU) were examined over a 24-month period. There was a significantly increased incidence of AAU during the months August to December (p less than 0.05). This increase was confined predominantly to the HLA-B27 negative group of patients (p less than 0.01). There was no significant monthly difference in incidence betwe...
متن کاملHLA-B27 associated spondyloarthropathy, an autoimmune disease based on crossreactivity between bacteria and HLA-B27?
Most autoimmune diseases are associated with certain HLA types. Therefore, spondyloarthropathies (SpA) strongly associated with HLA-B27, are also often classified as autoimmune diseases. This study questions whether SpA indeed fulfils the criteria of an autoimmune disease. The Medline database was searched for all reports between 1966 and April 1998 on the presence of autoimmune reactivity in S...
