Acute anterior uveitis and HLA-B27 subtypes.
The tissue antigen HLA-B27 is found in 50% of Dutch acute anterior uveitis (AAU) patients. The prevalence of HLA-B27 in the normal population is only 8%. However, only approximately 1% of HLA-B27+ individuals will develop AAU. Therefore, it is possible that the disease is associated with a particular B27 subtype. We typed lymphocytes of 36 B27+ AAU patients, of which 20 also had ankylosing spon...
متن کاملPrevalence of HLA-B27 and subtypes of HLA-B27 associated with ankylosing spondylitis in Galicia, Spain.
OBJECTIVE To assess the prevalence of HLA-B27 and its subtypes in both the normal population and in patients with Ankylosing Spondylitis (AS) in Galicia, Northwest Spain. METHODS The prevalence of HLA-B27 in the normal population was determined by checking the number of HLA-B27 positive samples in 308 subjects from different areas of Galicia who had donated organs over a period of 4 years. A ...
متن کاملPolymorphism of HLA-B27: 105 subtypes currently known.
HLA-B27 has a high degree of genetic polymorphism, with 105 known subtypes, named HLA-B*27:01 to HLA-B*27:106, encoded by 132 alleles. The most common subtypes associated with ankylosing spondylitis are HLA-B*27:05 (Caucasians), HLA-B*27:04 (Chinese), and HLA-B*27:02 (Mediterranean populations). For Chinese populations, HLA-B*27:04 is associated with a greater ankylosing spondylitis risk than H...
متن کاملHLA-B27 typing in the categorisation of uveitis in a HLA-B27 rich population.
AIMS To determine whether HLA-B27 typing helps the clinician in the diagnostic examination of uveitis in a HLA-B27 rich population and also whether the clinical picture of HLA-B27 positive unilateral acute or recurrent anterior uveitis (AAU) is distinguishable from the idiopathic negative form. METHODS During a 3 year period 220 consecutive patients with undetermined uveitis at onset were exa...
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...
