Aim: The aim of this study was to evaluate common human leucocyte antigen (HLA) associations in patients with juvenile idiopathic arthritis ( N =110), in patients with generalized aggressive periodontitis ( N =50) and in patients with chronic periodontitis ( N =102) in comparison to healthy controls (no periodontitis, no arthritis N =102). Material and methods: HLA‐class I and II markers were determined using microlymphocytotoxicity test and polymerase chain reaction with sequence specific primers. Statistical analyses were carried out by χ 2 ‐test and Yates' correction. If n <5 Fisher's exact test was performed. In the arthritis group the influence of HLA on attachment loss was determined by using backwards logistic regression considering age, gender, smoking, plaque level, and the duration of the disease. Results: In comparison with the controls HLA‐DRB3 * occurred more frequently in both females suffering from juvenile idiopathic arthritis (74.58% versus 54.54%, p =0.024) and females suffering from chronic periodontitis (73.02% versus 54.54%, p =0.035). Furthermore, among patients with juvenile idiopathic arthritis an increased odds ratio (OR) for attachment loss was found in subjects who expressed HLA‐A * 01 (OR=4.6, p =0.014) or HLA‐A * 01:DRB3 * (OR=4.3, p =0.031). Conclusion: HLA‐DRB3 * could be a common putative risk indicator for juvenile idiopathic arthritis and chronic periodontitis among females.
