Abstract: We have previously suggested that in a Japanese population the susceptible locus for Behcet's disease (BD) is HLA-B51 itself. To confirm this finding in another population, we performed HLA class I typing using the PCR-SSP method and analyzed eight polymorphic markers distributed within 1100 kb around the HLA-B gene using automated sequencer and subsequent automated fragment detection by fluorescent-based technology with the DNA samples of 84 Iranian patients with BD ...
Abstract: PT was performed by 2 methodes: 1- Needle prick. 2-- Intra dermal injection of normal salin. 83 % of BD patients presented a positive PT. Control subjects were composed of 101 healthy person, 46 Rheumatoid Arthritis, 5 Ankylosing Spondylitis, 18 Systemic Lupus Erythematosus (SLE). 3 Sclerodermia, and 1 permatomyositis. Among them 16% presented a positive PT. Only 3% had a positive PT with both needle prick and normal salin method. ...
Abstract: In a separate report we demonstrated that B5 cluster antigens acts as a leading factor for ocular injuries. The question is why in some patients, these antigens does not produce the same lesions. This may be due to a genetic factor(s) which determine resistance to ocular lesions. Two HLA antigens attracted our attention as possible factors. One from the class I (CW4), and the other from the class II (DQW1). DQW1 ...
Abstract: We have reported a 100% association of ocular type of BD with B5 cluster antigens. The HLA results of non ocular type shows respectively 30% and 40% of association with B5 and B5 cluster antigens. These results indicate that B5 cluster antigens are decreased in non ocular patients compared to 62% of normal population. Considering the etiologic fraction for B5 cluster in ocular type patients which was at its maximum ...
Abstract: Behcet's Disease (BD) has been found to be related to the first class HLA antigens, the B5. In Iran, B5 is present in 64% of BD patients versus 34% in normal population. The relative risk is 3.33. Uveitis has been demonstrated to be related to the presence of B5. in our study the posterior uveitis was present in 59% of patients with B5 versus 48% without it (p
Abstract: The association of B5 and uveitis has been previously demonstrated. 37 patients with ocular form were studied for HLA, ABC and DR antigens, with a large panel of antisera (A.O.H.W.C panel sera). Results are: Antigen Control Patient Relative R. ...
Abstract: One hundred and sixty-six patients with different forms of rheumatic diseases were tissue typed for 26 antigens of the A and B locus of the HLA system, using a modified KN cytotoxicity test. Among 25 patients with confirmed ankylosing spondylitis, 23 had HLA B27 (92 per cent), compared to 2.5 per cent in the normal controls. This confirms the strong association of HLA B27 with ankylosing spondylitis. Eight patients had ...
