Background To assess the association between HLA‐B57.01 (Human leukocyte antigen) and clinical parameters of chronic periodontitis in people living with HIV (PLWHIV). Methods All patients were recruited from the HIVCENTER at the University Hospital Frankfurt during April 2014 and July 2015. Periodontal examination included Periodontal Screening Index (PSI), Gingivalindex (GI), Bleeding on Probing Index (BOP), Periodontal Probing Depth (PD), Clinical Attachment Level (CAL) and DMF‐T Score (decayed, missing, filled teeth). Associations among periodontitis, HLA‐system and additional risk factors in PLWHIV were evaluated in multivariate analyses. Results One hundred PLWHIV were enrolled. Forty‐five patients were naive, meaning that these patients never took antiretroviral (ARV) drugs before, 55 patients treated with combined antiretroviral therapy (cART). Nineteen patients presented a positive HLA‐B 57.01 status. PLWHIV who were carriers of HLA‐B 57.01 had significantly lower PSI‐scores (Grade 3 or higher; 0/19 [0%] versus 16/41 [39%] versus 17/40 [42%]; p = < 0.001), GI‐scores (Grade 2 or higher; 0/19 [0%] versus 19/41 [46%] versus 28/40 [70%]; p = < 0.001) and BOP‐Scores (2/19 [1%] versus 38/41 [92%] versus 40/40 [100%]; p = < 0.001) in comparison to naive PLWHIV and PLWHIV receiving cART, who were both not carriers of HLA‐B 57.01. A lower value of PSI‐, GI‐ and BOP‐Score is associated with improved periodontal health. The adjusted odds ratio (OR) of periodontitis was decreased in patients who were carriers of HLA‐B 57.01 by measurement of PSI‐Score (OR = 0.006, 95% confidence interval (CI) = 0.001 to 0.026), GI‐Score (OR = 0.018, 95% confidence interval (CI) = 0.003 to 0.104) and BOP‐Score (OR = 0.003, 95% confidence interval (CI) = < 0.001 to 0.011). Conclusions HLA‐B 57.01 is an independent resistance indicator for generalized periodontitis in PLWHIV with respect to established cofactors.
