title: Human leukocyte antigen (HLA) DR4. Positive association with rapidly progressing periodontitis.
abstract: The relationship between human leukocyte antigens (HLA) determinants and periodontitis has been examined by several authors without showing any particular pattern. However, no study has investigated the HLA-D determinants, which are generally associated with immune disorders, and rapidly progressive periodontitis (RPP). The HLA profile of 10 RPP patients was compared with that of a healthy control population (n = 120). Although no significant difference was found for HLA-A, HLA-B, and HLA-C, HLA-DR4 of the HLA-D group was found in 80% of patients but only in 38.3% of controls. A high frequency of HLA-DR4 has been reported in rheumatoid arthritis (RA) patients. This finding may be significant in light of previous reports highlighting similarities between RA and periodontal disease.
