HLA-A26 is a risk factor for Behçet's disease ocular lesions.

Background: How HLA-A26 modulates Behçet's disease (BD) ocular lesions such as iridocyclitis and retinochorioiditis has not been scrutinized.

Methods: Ministry of Health, Labour and Welfare of Japan provided us a database of BD patients who were registered from 2003 to 2014. We selected patients who satisfied International Criteria for BD and whose data for HLA-A26 was available.

The influence of HLA-B51 on clinical manifestations among Japanese patients with Behçet's disease: A nationwide survey.

To scrutinize the influence of HLA-B51 to each clinical manifestation of patients with Behçet's disease (BD) using a database of the Ministry of Health, Labour and Welfare of Japan. The database of newly registered patients with BD was obtained from the Japanese Ministry of Health, Labour and Welfare. Patients who met International Criteria for Behçet's Disease (ICBD) and had data for HLA-B51 were selected and analyzed.

Clinical features of early-stage possible Behçet's disease patients with a variant-type major organ involvement in Japan.

Clinical data of patients with entro-, vasculo-, and neuro-variant possible Behçet's disease (BD) based on Japanese criteria has not yet comprehensively reported. This ongoing nation-wide registration has been carried out by the Japanese Ministry of Health, Labour and Welfare. The Ministry asked physicians who diagnosed a patient with confirmed or possible BD to register the patient data by filling out a registration form.
