Abstract
Autoimmune diseases are characterized by the body's own immune system attack to the self-tissues, a condition enabled, in predisposed subjects, by the reduction of self-tolerance. A central role has been recently recognized to post-translational modifications, since they can promote generation of neo-(auto)antigens and in turn an autoimmune response. During the last years great attention has been paid to citrullination, because of its role in inducing anti-citrullinated proteins/peptide antibodies (ACPA), a class of autoantibodies with diagnostic, predictive and prognostic value for Rheumatoid Arthritis (RA). Nonetheless, citrullination has been reported to be a process present in a wide range of inflammatory tissues. Indeed, citrullinated proteins have been detected also in other inflammatory arthritides and in inflammatory conditions other than arthritides (polymyositis, inflammatory bowel disease and chronic tonsillitis). Moreover, environmental exposure to cigarette smoke and nanomaterials of air pollution may be able to induce citrullination in lung cells prior to any detectable onset of inflammatory responses, suggesting that protein citrullination could be considered as a sign of early cellular damage. Accordingly, citrullination seems to be implicated in all those para-physiological processes, such as cells death pathways, in which intracellular calcium concentration raises to higher levels than in physiologic conditions: hence, peptidylarginine deiminases enzymes are activated during apoptosis, autophagy and NETosis, processes which are well-known to be implicated in autoimmunity. Taken together, these data support the hypothesis that rather than being a disease-dependent process, citrullination is an inflammatory-dependent condition that plays a central role in autoimmune diseases.

Abstract
Undifferentiated arthritis (UA) is a frequently occurring clinical presentation with a variable outcome. While some forms of UA will spontaneously remit, other forms will progress to chronic arthritis; an outcome that would preferably be prevented. Which immunological factors are normally at the basis of resolution of inflammation, and what, on the other hand, causes inflammation to persist? This review provides an overview of the immunological mechanisms involved in these two scenarios, including specific examples of how these mechanisms apply, or can be influenced in rheumatic diseases. Furthermore, what do we know about risk factors for chronic arthritis, such as the development of autoantibodies? The recent years have provided many insights concerning risk factors for autoantibody-positive versus autoantibody-negative rheumatoid arthritis, which are discussed along with a possible pathophysiological model incorporating autoantibodies into the larger process of disease development. Finally, the evolution of the autoantibody response over time is described.

Abstract
Periodontitis or Periodontal disease (PD) and Rheumatoid arthritis (RA) are two the most common chronic inflammatory diseases. Periodontitis is a biofilm associated destructive inflammatory disease of the periodontium caused by specific microorganisms. Rheumatoid arthritis is an autoimmune condition and is identified by elevated serum autoantibody titre directed against citrullinated peptides or rheumatoid factor. Periodontitis may involve some elements of autoimmunity. Recent studies have established that PD and RA show a common pathway and could be closely associated through a common dysregulation and dysfunction in inflammatory mechanism. The enzyme peptidyl arginine deiminase (PAD), expressed by Porphyromonas gingivalis (P. gingivalis) is responsible for the enzymatic deimination of arginine residuals to citrulline resulting in protein citrullination and its increased accumulation in RA. Citrullination by PAD may act as a putative biologic link between PD and RA. Association of Human leukocytic antigen-DR4 antigen has been established both with RA and PD. Several interleukins and inflammatory mediators (ILs) and Nuclear factor kappa beta ligand are linked to these common chronic inflammatory diseases. Antibodies directed against heat shock protein (hsp 70 ab) of P. gingivalis, P. melanogenicus and P. intermedia are raised in PD as well as RA. Both the conditions share many pathological and immunological similarities. Bacterial infection, genetic susceptibility, altered immune reaction and inflammatory mediators considered responsible for RA are also associated with PD. So it is plausible that a biological link may exist between PD and RA. Therapies aimed at modifying the expression and effect of inflammatory mediators and effector molecules such as matrix metalloproteinases, proinflammatory cytokines and autoantibodies of structural proteins may probably reduce the severity of both RA and PD.

Abstract
OBJECTIVE The objective of this study was to investigate the association between periodontitis (PD) and etanercept (ETN) discontinuation in anti-tumor necrosis factor (anti-TNF)-naive patients with rheumatoid arthritis (RA). METHODS This retrospective nationwide population-based cohort study identified 3359 anti-TNF-naive patients with RA (age at diagnosis ≥16 years) in whom ETN treatment was initiated using administrative data. We identified PD exposure within 5 years before ETN initiation and during ETN treatment. Cox proportional hazard models were used to assess ETN discontinuation risk associated with PD within 5 years before ETN initiation, shown as hazard ratios with 95% confidence intervals (CIs). Stratified analyses were performed on the basis of PD during ETN treatment to avoid violating the Cox regression assumptions. RESULTS Patients with PD history during the 5 years before ENT initiation had a higher risk of ETN discontinuation compared with those without such history; the hazard ratios of ETN discontinuation were 1.27 (95% CI, 1.01-1.60) and 1.17 (95% CI, 1.06-1.30) among patients with and without PD during ETN treatment, respectively. Other risk factors included age older than 65 years and daily prednisolone dose greater than 10 mg/d within 1 year before ETN initiation. Concomitant methotrexate, leflunomide, salazopyrin, or hydroxychloroquine administration had a protective effect on ETN discontinuation in patients without PD during ETN treatment, but the protective effect by leflunomide, salazopyrin, and hydroxychloroquine was attenuated in patients with PD during ETN treatment (P for interaction <0.05). CONCLUSIONS A PD history within 5 years before ETN administration was associated with increased ETN discontinuation risk in anti-TNF-naive patients with RA.

Abstract
OBJECTIVE The aim of this study was to examine the link between AS and periodontitis. METHODS Medline, Embase, AMED, CINAHL, Web of Science and Google Scholar were searched to identify eligible studies that were selected and reviewed independently by at least two authors. RESULTS Six case-control studies were included in the review. Study size ranged from 90 to 40 926 participants. The prevalence of periodontitis ranged from 38% to 88% in AS patients and from 26% to 71% in controls. As there was low-level heterogeneity (I(2) = 13%), using fixed effects analysis the overall pooled estimate of the odds ratios for periodontitis was 1.85 (95% CI 1.72, 1.98). There was no evidence of publication bias. CONCLUSION The results led to the need for a further large study with sufficient statistical power to detect the desired effect size, taking into account potential confounding factors and using validated measures of AS and periodontitis.

Abstract
OBJECTIVE To examine the degree to which shared risk factors explain the relationship of periodontitis (PD) to rheumatoid arthritis (RA) and to determine the associations of PD and Porphyromonas gingivalis with pathologic and clinical features of RA. METHODS Patients with RA (n = 287) and patients with osteoarthritis as disease controls (n = 330) underwent a standardized periodontal examination. The HLA-DRB1 status of all participants was imputed using single-nucleotide polymorphisms from the extended major histocompatibility complex. Circulating anti-P gingivalis antibodies were measured using an enzyme-linked immunosorbent assay, and subgingival plaque was assessed for the presence of P gingivalis using polymerase chain reaction (PCR). Associations of PD with RA were examined using multivariable regression. RESULTS Presence of PD was more common in patients with RA and patients with anti-citrullinated protein antibody (ACPA)-positive RA (n = 240; determined using the anti-cyclic citrullinated peptide 2 [anti-CCP-2] test) than in controls (35% and 37%, respectively, versus 26%; P = 0.022 and P = 0.006, respectively). There were no differences between RA patients and controls in the levels of anti-P gingivalis or the frequency of P gingivalis positivity by PCR. The anti-P gingivalis findings showed a weak, but statistically significant, association with the findings for both anti-CCP-2 (r = 0.14, P = 0.022) and rheumatoid factor (RF) (r = 0.19, P = 0.001). Presence of PD was associated with increased swollen joint counts (P = 0.004), greater disease activity according to the 28-joint Disease Activity Score using C-reactive protein level (P = 0.045), and higher total Sharp scores of radiographic damage (P = 0.015), as well as with the presence and levels of anti-CCP-2 (P = 0.011) and RF (P < 0.001). The expression levels of select ACPAs (including antibodies to citrullinated filaggrin) were higher in patients with subgingival P gingivalis and in those with higher levels of anti-P gingivalis antibodies, irrespective of smoking status. Associations of PD with established seropositive RA were independent of all covariates examined, including evidence of P gingivalis infection. CONCLUSION Both PD and P gingivalis appear to shape the autoreactivity of RA. In addition, these results demonstrate an independent relationship between PD and established seropositive RA.

Abstract
INTRODUCTION Prior studies have demonstrated an increased frequency of antibodies to Porphyromonas gingivalis (Pg), a leading agent of periodontal disease, in rheumatoid arthritis (RA) patients. However, these patients generally had long-standing disease, and clinical associations with these antibodies were inconsistent. Our goal was to examine Pg antibody responses and their clinical associations in patients with early RA prior to and after disease-modifying antirheumatic drug (DMARD) therapy. METHODS Serum samples from 50 DMARD-naïve RA patients were tested using an enzyme-linked immunosorbent assay with whole-Pg sonicate. For comparison, serum samples were tested from patients with late RA, patients with other connective tissue diseases (CTDs), age-similar healthy hospital personnel and blood bank donors. Pg antibody responses in early RA patients were correlated with standard RA biomarkers, measures of disease activity and function. RESULTS At the time of enrollment, 17 (34%) of the 50 patients with early RA had positive immunoglobulin G (IgG) antibody responses to Pg, as did 13 (30%) of the 43 patients with late RA. RA patients had significantly higher Pg antibody responses than healthy hospital personnel and blood bank donors (P < 0.0001). Additionally, RA patients tended to have higher Pg antibody reactivity than patients with other CTDs (P = 0.1), and CTD patients tended to have higher Pg responses than healthy participants (P = 0.07). Compared with Pg antibody-negative patients, early RA patients with positive Pg responses more often had anti-cyclic citrullinated peptide (anti-CCP) antibody reactivity, their anti-CCP levels were significantly higher (P = 0.03) and the levels of anti-Pg antibodies correlated directly with anti-CCP levels (P < 0.01). Furthermore, at the time of study entry, the Pg-positive antibody group had greater rheumatoid factor values (P = 0.04) and higher inflammatory markers (erythrocyte sedimentation rate, or ESR) (P = 0.05), and they tended to have higher disease activity scores (Disease Activity Score based on 28-joint count (DAS28)-ESR and Clinical Disease Activity Index) and more functional impairment (Health Assessment Questionnaire). In Pg-positive patients, greater disease activity was still apparent after 12 months of DMARD therapy. CONCLUSIONS A subset of early RA patients had positive Pg antibody responses. The responses correlated with anti-CCP antibody reactivity and to a lesser degree with ESR values. There was a trend toward greater disease activity in Pg-positive patients, and this trend remained after 12 months of DMARD therapy. These findings are consistent with a role for Pg in disease pathogenesis in a subset of RA patients.

Abstract
Rheumatoid arthritis, currently regarded as a complex multifactorial disease, was initially characterized as such at the turn of the 19th century. Ever since, multiple lines of investigation have attempted to elucidate the etiological factor(s) involved in disease incidence. Genes--including those risk alleles within HLA-DR4--have been implicated but are insufficient to explain the vast majority of cases. Several environmental factors, therefore, are being studied. Among them, the role of periodontal disease and Porphyromonas gingivalis in the pathogenesis of rheumatoid arthritis has attracted both clinical and bench interest given supportive epidemiologic and mechanistic data.

Abstract
PURPOSE OF REVIEW Despite the progress toward understanding the molecular pathogenesis of rheumatoid arthritis (RA), its cause remains elusive. Genes are important but rather insufficient to explain the majority of RA cases. This review describes the novel data supporting the microbiome and its interactions with the human host as potential en('in')vironmental factors in RA pathogenesis. RECENT FINDINGS Animal models of inflammatory arthritis have shown that the presence of bacteria in mucosal surfaces is sufficient to alter local and systemic host immune responses and elicit joint inflammation. Human RA studies have focused on three mucosal sites: the gut, the gingiva, and the respiratory tree. The oral microbiome, and specifically Porphyromonas gingivalis, has long been implicated. Novel sequencing technologies have allowed investigations into the role of the gut microbiome in the development of autoimmune arthritis. Most recently, the pulmonary parenchyma has also been described as yet another possible mucosal site of initiation of autoimmunity in RA. SUMMARY Emerging data implicate the microbiome in RA pathogenesis. Mucosal sites exposed to a high load of bacterial antigens--such as the periodontium, lung, and gut--may represent the initial site of autoimmune generation. If validated, these findings could lead to the discovery of potential biomarkers and therapeutic approaches in the preclinical and clinical phases of RA.

Abstract
AIM It is hypothesized that self-perceived oral health and periodontal status are worse in chronic periodontitis (CP) patients with rheumatoid arthritis (RA) compared to CP patients without RA. The aim of the present study was to assess self-perceived oral health and periodontal parameters in CP patients with and without RA. METHODS Fifty CP patients with RA and 50 CP patients without RA were included. Information regarding sociodemographic characteristics and self-perceived oral symptoms were collected using a questionnaire. Periodontal parameters (plaque index, bleeding on probing, probing depth, clinical attachment loss, number of missing teeth, and marginal bone loss) were recorded. RESULTS There was no significant difference in socioeconomic status, education status, self-perceived oral symptoms, and periodontal parameters among CP patients with and without RA. CONCLUSIONS Self-perceived oral health and periodontal parameters are mainly governed by the intensity of CP, and the role of RA in this context seems to be rather secondary.

Abstract
AIM The aim of the current research was to investigate whether possible associations exist between indices of clinically-defined periodontitis and several systemic medical conditions in outpatients referred to a special hospital clinic. METHODS The study sample consisted of 3360 outpatients aged 45-65 years. Data were collected by means of an oral clinical examination and a self-administered questionnaire. Statistical analysis of the questionnaire items was done with Fisher's exact test and the logistic regression model to assess possible associations between systemic medical conditions as independent variables, and the relative frequency of periodontal pockets ≥5 mm and clinical attachment loss (CAL) of ≥6 mm as dependent variables. RESULTS The depth of periodontal pockets was significantly associated with male sex, the presence of vascular disease, hypertension, stroke, heart attack, diabetes mellitus, other endocrine diseases, thyroid disease, respiratory allergies, and rheumatoid arthritis. CAL was significantly associated with the mentioned conditions, and also infective endocarditis and chronic obstructive pulmonary disease, but not other endocrine and thyroid disease. CONCLUSIONS The findings confirm the results from previous investigations in which a number of systemic medical conditions were significantly associated with probing pocket depth and/or CAL.

Abstract
BACKGROUND Antibodies to citrullinated proteins are a hallmark of rheumatoid arthritis (RA). Porphyromonas gingivalis peptidylarginine deiminase (PPAD) has been implicated in the initiation of RA by generating citrullinated neoantigens and due to its ability to autocitrullinate. OBJECTIVES To define the citrullination status and biology of PPAD in P gingivalis and to characterise the anti-PPAD antibody response in RA and associated periodontal disease (PD). METHODS PPAD in P gingivalis cells and culture supernatant were analysed by immunoblotting and mass spectrometry to detect citrullination. Recombinant PPAD (rPPAD), inactive mutant PPAD (rPPAD(C351S)), and N-terminal truncated PPAD (rPPAD(Ntx)) were cloned and expressed in Escherichia coli. Patients with RA and healthy controls were assayed for IgG antibodies to citrullinated rPPAD and unmodified rPPAD(C351S) by ELISA. Anti-PPAD antibodies were correlated with anti-cyclic citrullinated peptide (third-generation) antibody levels, RA disease activity and PD status. RESULTS PPAD from P gingivalis is truncated at the N-terminal and C-terminal domains and not citrullinated. Only when artificially expressed in E coli, full-length rPPAD, but not truncated (fully active) rPPAD(Ntx), is autocitrullinated. Anti-PPAD antibodies show no heightened reactivity to citrullinated rPPAD, but are exclusively directed against the unmodified enzyme. Antibodies against PPAD do not correlate with anti-cyclic citrullinated peptide levels and disease activity in RA. By contrast, anti-PPAD antibody levels are significantly decreased in RA patients with PD. CONCLUSIONS PPAD autocitrullination is not the underlying mechanism linking PD and RA. N-terminal processing protects PPAD from autocitrullination and enhances enzyme activity. Anti-PPAD antibodies may have a protective role for the development of PD in patients with RA.

Abstract
Periodontitis has been implicated as a risk factor for metabolic disorders such as type 2 diabetes, atherosclerotic vascular diseases, and non-alcoholic fatty liver disease. Although bacteremias from dental plaque and/or elevated circulating inflammatory cytokines emanating from the inflamed gingiva are suspected mechanisms linking periodontitis and these diseases, direct evidence is lacking. We hypothesize that disturbances of the gut microbiota by swallowed bacteria induce a metabolic endotoxemia leading metabolic disorders. To investigate this hypothesis, changes in the gut microbiota, insulin and glucose intolerance, and levels of tissue inflammation were analysed in mice after oral administration of Porphyromonas gingivalis, a representative periodontopathogens. Pyrosequencing revealed that the population belonging to Bacteroidales was significantly elevated in P. gingivalis-administered mice which coincided with increases in insulin resistance and systemic inflammation. In P. gingivalis-administered mice blood endotoxin levels tended to be higher, whereas gene expression of tight junction proteins in the ileum was significantly decreased. These results provide a new paradigm for the interrelationship between periodontitis and systemic diseases.

Abstract
AIM To evaluate and compare the clinical effects of ibuprofen and diclofenac sodium on bleeding during periodontal surgery. MATERIALS AND METHODS Thirteen medically healthy men and women of mean age 37.5±17.67 (mean age± standard deviation) were selected for the study. All the subjects were divided into three groups: control (C) and test groups (T1) and (T2). Each subject of T1 group and T2 group was given ibuprofen and diclofenac sodium respectively, prior to surgery. Bleeding times of patients were recorded prior to performance of periodontal flap surgical procedures. RESULTS It was found that there was increased bleeding time and increased peri-operative bleeding when ibuprofen and diclofenac sodium were taken prior to surgery and this was statistically significant. (2.5538 (T1), 1.8385 (T2) versus 1.2385 (C) minute, p= .001) (mean blood loss) and (62.0325 ± 9.0594 (T1), 51.082 ± 9.792 (T2) versus 37.4992 ± 5.99 (C) millilitre, p = .000). CONCLUSION The findings of this study suggested that pre-operative administration of ibuprofen and diclofenac sodium could increase bleeding time and peri - operative blood loss.

Abstract
AIM To evaluate the prevalence and severity of periodontal disease in patients with rheumatoid arthritis (RA) who attended a rheumatology clinic in a university hospital. METHODS All consecutive patients with RA who attended the rheumatology clinic between June 2009 and January 2010 were asked to enroll in this study. All participants answered questionnaires, which included demographic data, medical history, medications used and smoking habits. A full mouth periodontal examination, including gingival index, plaque index, probing pocket depth and clinical attachment level was performed. Only cases that had at least 20 teeth were included in this study. Rheumatoid arthritis parameters, including number of tender and swollen joints, erythrocyte sedimentation rate, the presence of rheumatoid factor (RF), hand radiographs, Disease Activity Index (DAS) and health status using the Thai Health Assessment Questionnaire (HAQ), were determined. The association between RA parameters and periodontal condition was examined. RESULTS There were 196 participants (87.2% female) with a mean age of 51.7 ± 9.70 years, mean disease duration of 9.62 ± 7.0 years and mean DAS score of 4.64 ± 1.25. Eighty-two per cent were RF-positive. Moderate and severe periodontitis were found in 42% and 57%, respectively. Higher age, male gender, previous or current smoking and high level of plaque score were associated with severe periodontal disease. No differences in RA parameters were found between groups of patients who had moderate and severe periodontitis. CONCLUSIONS We found a high prevalence of periodontitis in Thai patients with RA. However, there was no association between RA parameters and periodontal conditions.

Abstract
Rheumatological diseases and periodontal disease are both characterized by dysregulation of the host inflammatory response. The aim of this study was to determine the possible relationship between periodontitis and psoriatic arthritis (PsA). Fifty-one adults with PsA (27 men and 24 women; mean age 41.73 ± 11.27 years) and 50 age- and gender-balanced systemically healthy control subjects participated in the study. Participants' periodontal status as determined by probing pocket depth, clinical attachment loss (CAL), plaque index, and gingival index was evaluated. The CAL levels of the PsA group were significantly higher than those of the control group (p < 0.05) There were no statistically significant differences in the frequency of periodontitis, probing pocket depth, plaque index, or gingival index between the two groups. The results of the present study show that periodontitis severity as determined by CAL was higher in the PsA group; therefore, periodontal evaluation must be considered when PsA is diagnosed.

Abstract
Background Immunoglobulin (Ig)A nephropathy (IgAN) is the most common form of primary glomerulonephritis in the world. Some bacteria were reported to be the candidate of the antigen or the pathogenesis of IgAN, but systematic analysis of bacterial flora in tonsil with IgAN has not been reported. Moreover, these bacteria specific to IgAN might be candidate for the indicator which can predict the remission of IgAN treated by the combination of tonsillectomy and steroid pulse. Methods and Findings We made a comprehensive analysis of tonsil flora in 68 IgAN patients and 28 control patients using Denaturing gradient gel electrophoresis methods. We also analyzed the relationship between several bacteria specific to the IgAN and the prognosis of the IgAN. Treponema sp. were identified in 24% IgAN patients, while in 7% control patients (P = 0.062). Haemophilus segnis were detected in 53% IgAN patients, while in 25% control patients (P = 0.012). Campylobacter rectus were identified in 49% IgAN patients, while in 14% control patients (P = 0.002). Multiple Cox proportional-hazards model revealed that Treponema sp. or Campylobactor rectus are significant for the remission of proteinuria (Hazard ratio 2.35, p = 0.019). There was significant difference in remission rates between IgAN patients with Treponema sp. and those without the bacterium (p = 0.046), and in remission rates between IgAN patients with Campylobacter rectus and those without the bacterium (p = 0.037) by Kaplan-Meier analysis. Those bacteria are well known to be related with the periodontal disease. Periodontal bacteria has known to cause immune reaction and many diseases, and also might cause IgA nephropathy. Conclusion This insight into IgAN might be useful for diagnosis of the IgAN patients and the decision of treatment of IgAN.

Abstract
Periodontal disease (POD) may affect rheumatic diseases severity, but there are no data regarding the effect of its treatment on disease activity in SLE patients under immunosuppressive therapy. Forty-nine consecutive SLE patients (SLEDAI ≥ 2) with POD and under corticosteroid and cyclophosphamide pulse therapy (IVCYC) were selected. Periodontal assessment included bleeding gingival index (BGI), probing depth (PD), and probing attachment level (PAL). At entry, POD was defined as BGI > 1 and patients were assigned to groups according to the availability of odontological intervention in TREATED (n = 32) and NOT TREATED (n = 17). SLEDAI and POD parameters were determined at entry and after 3 months. Age, female gender, and race were alike among TREATED and NOT TREATED (p > 0.05). Both groups had also comparable disease duration (10.7 ± 6.8 vs. 11.0 ± 6.6, p = 0.83), IVCYC number (5.8 ± 4.8 vs. 4.5 ± 4.8, p = 0.17), and SLEDAI (5.9 ± 4.2 vs. 6.3 ± 4.3, p = 0.73) as well as POD parameters [BGI (40.8 ± 31.0 vs. 40.7 ± 36.2 %, p = 0.89), PD (1.7 ± 1.8 vs. 1.5 ± 0.60 mm, p = 0.80), and PAL (2.5 ± 1.9 vs. 1.9 ± 1.1 mm, p = 0.18)]. At the end of the study, TREATED group had a significant improvement in SLEDAI (5.9 ± 4.2 vs. 3.4 ± 3.3, p = 0.04) with a paralleled reduction in BGI (40.8 ± 31.0 vs. 15.2 ± 17.2 %, p < 0.01), PD (1.7 ± 1.8 vs. 1.1 ± 0.3 mm, p < 0.01), and PAL (2.5 ± 1.9 vs. 1.7 ± 0.9 mm, p < 0.01). In contrast, SLEDAI (6.3 ± 4.3 vs. 6.0 ± 5.5, p = 0.40) and POD parameters [BGI (p = 0.33), PD (p = 0.91), and PAL (p = 0.39)] remained largely unchanged in NOT TREATED group. Periodontal disease treatment seems to have a beneficial effect in controlling disease activity in SLE patients under immunosuppressive therapy. Therefore, management of this modifiable risk factor is recommended.

Abstract
Periodontal disease (PD) is an inflammatory disease affecting tooth-supporting tissues in which interaction of specific bacteria and the host’s immune responses play a pivotal role. The pathogenic bacteria associated with PD are a source of systemic inflammation as they have the ability to enter systemic circulation during everyday tasks such as brushing teeth and chewing food. Alzheimer’s disease (AD) is a form of dementia whereby inflammation is thought to play a key role in its pathogenesis and the risk of developing the disease increasing with age. The exact aetiology of the late-onset AD is unknown but peripheral infections are being considered as a potential risk factor.

Abstract
We herein present the case of a 47-year-old woman with rheumatoid arthritis (RA) complicated by Kartagener's syndrome (KS). Although her RA disease activity score (DAS28-CRP) decreased following the administration of periodontitis treatment and etanercept, she did not achieve symptom relief or DAS28-CRP remission. After undergoing surgery for chronic sinusitis, her articular symptoms improved and the DAS28-CRP declined to the level of remission. Patients with KS may develop respiratory infections due to an impaired defense mechanism against microbes in the airway. Therefore, in patients with RA complicated by KS, comprehensive management of infection, including surgical therapy for sinusitis, is needed to reduce the RA disease activity.

Abstract
PURPOSE OF REVIEW This article reviews the link between periodontitis and rheumatoid arthritis (RA) with regard to similarities in genetic risk factors and immunopathogenesis. Emphasis is paid to the potential role of the periodontal pathogen Porphyromonas gingivalis in the etiopathogenesis of both periodontitis and RA, in particular by post-translational modification of arginine into citrulline. RECENT FINDINGS P. gingivalis, a major periodontal pathogen, is presently known as the only bacterium in the oral flora which contains a peptidyl arginine deiminase enzyme (PAD). This enzyme is necessary for citrullination. As a result, citrullinated proteins and P. gingivalis PAD, PAD2 and PAD4 (expressed by infiltrating neutrophils) are found in periodontal tissues. Autoantibodies directed to citrullinated proteins, so-called anticitrullinated protein antibodies (ACPAs), are found to be present in gingival crevicular fluid originating from inflamed gingival tissue. Furthermore, treatment studies have revealed that nonsurgical periodontal treatment, that is removal of sub-gingival calculus and biofilm deposits, is accompanied by a reduction in the severity of RA. SUMMARY In this study the similarities in immune response and tissue degradation between RA and periodontitis are reviewed. It is shown that the two diseases share the same environmental and genetic risk factors, apart from the fact that there is a link between both diseases via citrullination of proteins by human PAD and P. gingivalis PAD.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic inflammatory disorder that leads to joint damage, deformity, and pain. It affects approximately 1% of adults in developed countries. Periodontitis is a chronic oral infection, caused by inflammatory reactions to gram-negative anaerobic bacteria, and affecting about 35 to 50% of adults. If left untreated, periodontitis can lead to tooth loss. A significant association has been shown to exist between periodontitis and RA in observational studies. Some intervention studies have suggested that periodontal treatment can reduce serum inflammatory biomarkers such as C-reactive protein, or erythrocyte sedimentation rate. We hypothesize that periodontitis could be an aggravating factor in patients with RA, and that its treatment would improve RA outcomes. The aim of this clinical trial is to assess the effect of periodontal treatment on the biological and clinical parameters of patients with RA. METHODS/DESIGN The ESPERA (Experimental Study of Periodontitis and Rheumatoid Arthritis) study is an open-label, randomized, controlled trial. Subjects with both RA and periodontitis will be recruited at two university hospitals in southwestern France. In total, 40 subjects will be randomized into two arms (intervention and control groups), and will be followed up for 3 months. Intervention will consist of full-mouth supra-gingival and sub-gingival non-surgical scaling and root planing, followed by systemic antibiotic therapy, local antiseptics, and oral hygiene instructions. After the 3-month follow-up period, the same intervention will be applied to the subjects randomized to the control group.The primary outcome will be change of in Disease Activity Score in 28 Joints (DAS28) at the end of the follow-up period. Secondary outcomes will be the percentages of subjects with 20%, 50%, and 70% improvement in disease according to the American College of Rheumatology criteria. Health-related quality of life assessments (the Health Assessment Questionnaire and the Geriatric Oral Health Assessment Index) will also be compared between the two groups. DISCUSSION Evidence-based management of potential aggravating factors in subjects with active RA could be of clinical importance, yet there are few randomized controlled trials on the effect of periodontal treatment on the clinical parameters of RA. The ESPERA trial is designed to determine if non-surgical periodontal treatment could improve clinical outcomes in patients with active RA, and the quality of life of these patients. TRIAL REGISTRATION The ESPERA Trial was registered in Current Controlled Trials [ISRCTN79186420] on 2012/03/20. The trial started recruiting on 2012/03/06.

Preventive and therapeutic anti-TNF-α therapy with pentoxifylline decreases arthritis and the associated periodontal co-morbidity in mice. Life Sci 2013; 93:423-8. [PMID: 23911669 DOI: 10.1016/j.lfs.2013.07.022] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2013] [Revised: 07/02/2013] [Accepted: 07/19/2013] [Indexed: 01/29/2023]
Abstract
AIMS The association between rheumatoid arthritis (RA) and periodontal disease (PD) has long been studied and some reports suggest that treating RA may improve the associated PD, and vice versa. This study aimed to evaluate the effects of an anti-tumor necrosis factor (TNF)-α therapy with pentoxifylline (PTX) in an experimental model of RA-associated PD. MAIN METHODS Male C57BL/6 mice were subjected to chronic antigen-induced arthritis (AIA) and daily treated with PTX (50mg/kg, i.p.) using preventive (Pre-PTX) or therapeutic (The-PTX) strategies. Fourteen days after the antigen challenge, mice were euthanized and knee joints, maxillae and serum were collected for microscopic and/or immunoenzymatic analysis. KEY FINDINGS AIA triggered significant leukocyte recruitment to the synovial cavity, tissue damage and proteoglycan loss in the knee joint. Pre-PTX and The-PTX regimens decreased these signs of joint inflammation. The increased levels of TNF-α and IL-17 in periarticular tissues of AIA mice were also reduced by both PTX treatments. Serum levels of C-reactive protein, which were augmented after AIA, were reduced by the PTX regimens. Concomitantly to AIA, mice presented alveolar bone loss, and recruitment of osteoclasts and neutrophils to periodontal tissues. Pre-PTX and The-PTX prevented and treated these signs of PD. PTX treatment also decreased TNF-α and increased IL-10 expression in the maxillae of AIA mice, although it did not affect the expression of IFN-γ and IL-17. SIGNIFICANCE The current study shows the anti-inflammatory and bone protective effects of preventive and therapeutic PTX treatments, which decreased the joint damage triggered by AIA and the associated periodontal co-morbidity.

Abstract
To evaluate clinical outcomes and effects of non-surgical periodontal therapy on serum, gingival crevicular fluid (GCF) interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) levels in chronic periodontitis patients with/without rheumatoid arthritis (RA), fifteen RA patients with chronic periodontitis (RA-P) and 15 systemically healthy non-RA chronic periodontitis patients (H-P) were recruited. Clinical periodontal recordings, GCF, and blood samples were obtained at baseline, 1, 3, and 6 months after periodontal treatment. GCF, serum IL-1β, TNF-α levels were analyzed by ELISA. Disease activity score 28 (DAS28) was used to assess RA clinical morbidity. Study groups were compared by Mann-Whitney U test. Wilcoxon test was used to compare the data at baseline, 1, 3, and 6 months after periodontal therapy within the same group. DAS28 decreased significantly after periodontal therapy in RA-P group (p < 0.01). Serum TNF-α concentrations of H-P group were significantly higher than those of RA-P group (p < 0.01), whereas IL-1β levels were similar. No significant change was observed in serum levels of these cytokines after periodontal therapy. GCF IL-1β amounts decreased significantly in both groups following treatment (p < 0.01). At 6-months, H-P GCF IL-1β concentrations were significantly lower than baseline. DAS28 and GCF IL-1β correlated with clinical periodontal indices (p < 0.01). Significant decreases in DAS28 and GCF IL-1β amounts after periodontal treatment suggest that periodontal therapy synergizes with systemic RA therapy to improve RA status.

Abstract
During the last two to three decades our understanding of the immunobiology of periodontal disease has increased exponentially, both with respect to the microbial agents triggering the disease process and the molecular mechanisms of the host engagement maintaining homeostasis or leading to collateral tissue damage. These foundational scientific findings have laid the groundwork for translating cell phenotype, receptor engagement, intracellular signaling pathways and effector functions into a 'picture' of the periodontium as the host responds to the 'danger signals' of the microbial ecology to maintain homeostasis or succumb to a disease process. These findings implicate the chronicity of the local response in attempting to manage the microbial challenge, creating a 'Double Indemnity' in some patients that does not 'insure' health for the periodontium. As importantly, in reflecting the title of this volume of Periodontology 2000, this review attempts to inform the community of how the science of periodontal immunology gestated, how continual probing of the biology of the disease has led to an evolution in our knowledge base and how more recent studies in the postgenomic era are revolutionizing our understanding of disease initiation, progression and resolution. Thus, there has been substantial progress in our understanding of the molecular mechanisms of host-bacteria interactions that result in the clinical presentation and outcomes of destructive periodontitis. The science has embarked from observations of variations in responses related to disease expression with a focus for utilization of the responses in diagnosis and therapeutic outcomes, to current investigations using cutting-edge fundamental biological processes to attempt to model the initiation and progression of soft- and hard-tissue destruction of the periodontium. As importantly, the next era in the immunobiology of periodontal disease will need to engage more sophisticated experimental designs for clinical studies to enable robust translation of basic biologic processes that are in action early in the transition from health to disease, those which stimulate microenvironmental changes that select for a more pathogenic microbial ecology and those that represent a rebalancing of the complex host responses and a resolution of inflammatory tissue destruction.

Abstract
BACKGROUND Porphyromonas gingivalis has been implicated as an etiologic agent of rheumatoid arthritis (RA) because of the expression of peptidylarginine deiminase. The present study evaluates whether periodontal treatment may affect serum antibodies to P. gingivalis and citrulline levels in relation to disease activity of RA. METHODS Fifty-five patients with RA were randomly assigned to receive oral hygiene instruction and supragingival scaling (treatment group, n = 26) or no periodontal treatment (control group, n = 29). Periodontal and rheumatologic parameters and serum levels of cytokine and inflammatory markers citrulline and immunoglobulin (Ig)G to P. gingivalis were examined at baseline and 8 weeks later. RESULTS Both groups did not differ statistically in any parameters except percentage of sites with probing depth and clinical attachment level ≥ 4 mm at baseline. The treatment group exhibited a significantly greater decrease in disease activity score including 28 joints using C-reactive protein (DAS28-CRP) (P = 0.02), serum levels of IgG to P. gingivalis hemin binding protein (HBP)35 (P = 0.04), and citrulline (P = 0.02) than the control group. Serum levels of IgG to P. gingivalis HBP35 were significantly correlated positively with those of anti-cyclic citrullinated peptide antibodies (P = 0.0002). The same correlation was obtained between serum levels of IgG to P. gingivalis-sonicated extracts and those of rheumatoid factor (P = 0.02). CONCLUSIONS These results suggest that supragingival scaling decreases DAS28-CRP and serum levels of IgG to P. gingivalis HBP35 and citrulline in patients with RA. These observations may reflect a role of P. gingivalis in the protein citrullination, which is related to the pathogenesis of RA.

Abstract
CONTEXT Systemic autoimmune and inflammatory diseases often manifest oral lesions in their earliest stages, and early diagnosis, which may be spurred by a dental examination, is key for improved outcomes. After systemic diagnosis, oral lesions benefit from specialized care by dentists in collaboration with the medical team. This review aims to educate dental clinicians about the most relevant systemic autoimmune and inflammatory conditions with accompanying oral lesions, their implications for health, and management strategies supported by the biomedical literature and clinical experience. Ulcerative conditions including Behcet and Crohn diseases are discussed, along with rheumatic conditions including Sjögren syndrome, lupus erythematosus, and rheumatoid arthritis. EVIDENCE ACQUISITION Evidence was accumulated through PubMed searches using pertinent keywords for each subsection. References were reviewed and original publications examined to verify the accuracy of the information. We focused on evidence included in current reviews and randomized trials. Recommendations were supported by multiple studies and consensus expert opinion. EVIDENCE SYNTHESIS Disease phenotypes described and clinical recommendations were synthesized from best-quality evidence available for each disease. Efforts were made to describe evidence selection within each disease section. CONCLUSIONS Dentists play an important role in the early detection and multidisciplinary medical management of complex autoimmune diseases. It is important to recognize prevalent medical and dental issues and special needs of patients with autoimmune conditions. The management of many inflammatory conditions is similar, and often begins with the use of topical steroids, analgesics, and antimicrobial treatments, in addition to careful attention to oral hygiene and appropriate fluoride usage. In this brief review, we aim to discuss the presentation/prevalence, diagnosis, and treatment of oral manifestations encountered in autoimmune, autoinflammatory and systemic chronic inflammatory diseases. Systemic autoimmune conditions are estimated to affect 5% to 8% of Americans.(1) Oral manifestations are encountered with high frequency, and are often the first clinical signs or symptoms of the general disease. Optimal management of complex autoimmune diseases requires a multidisciplinary medical team including dentists to care for lesions of the oral cavity. The dental practitioner may be asked to play a primary role in the diagnosis of such conditions and to participate with other health professionals working together to achieve effective clinical management. To aid in this process, we discuss in this article the current general knowledge of systemic autoimmune conditions that present with prevalent oral manifestations. The focus is on the diagnosis and management of the oral component of each disease. Importantly, whereas the etiology and pathogenesis and systemic clinical presentation may vary, presentation in the oral cavity is often similar and many conditions involve oral ulcerations. For this reason, we discuss the differential diagnosis and management of the most common oral ulcerations in a general section and subsequently address individual conditions that present with oral ulcerations. Similarly, treatment of various autoimmune/inflammatory oral conditions is often common and involves modulation or suppression of the immune response locally and/or systemically and will be therefore addressed in a common section as well as individually for each disease when unique treatment regimens are recommended. We present here our general treatment recommendations based on clinical experience and literature review; however, it is critical that good clinical judgment and specifics of an individual case should determine the appropriate dental/oral medicine intervention for a specific patient.

Abstract
OBJECTIVES The aims of the Oral Status And Rheumatoid Arthritis (OSARA) cross-sectional study were to study the oral health-related quality of life and to assess the associated factors in a population of outpatients with rheumatoid arthritis in France. METHODS The data were collected by five trained and standardised dentists who asked each subject the questions of a socio-demographic, behavioural and medical questionnaire, which was completed with the medical records, and performed the dental examination. Each subject filled out two self-assessment questionnaires: the Health Assessment Questionnaire and the General Oral Health Assessment Index. RESULTS Seventy-three subjects were included. The mean age of the participants was 60.2 ± 11.9 years and 75.3% were women. For 58.3% of the subjects, their self-perceived oral health-related quality of life was described as poor. The logistic regression analysis found that a small number of teeth and marked difficulties in dressing and grooming were associated with bad oral health-related quality of life [ORa = 10.5 (1.96-56.19) and ORa = 4.3 (1.15-15.77), respectively]. CONCLUSIONS More care should be given to the prevention of dental diseases in order to improve the oral health-related quality of life of patients with rheumatoid arthritis and their self-esteem, which will already be heavily affected.

Abstract
Periodontitis and rheumatoid arthritis are chronic inflammatory diseases commonly seen in the elderly. It has been proposed that the two conditions are interrelated and influence the severity of each other. Recently, the role of Porphyromonas gingivalis, a periodontopathogen, has been explained in the pathogenesis and progression of rheumatoid arthritis. It can be inferred from the present review that the two conditions share a common pathobiology, genetics and environmental risk factors. Furthermore, a thorough understanding of the aforementioned mechanisms might enable the development of conjoint treatment modalities beneficial in treating the geriatric population afflicted by both the disorders.

Abstract
This systematic review considers the evidence available for a relationship between periodontal disease and rheumatoid arthritis. MEDLINE/PubMed, CINAHL, DOSS, Embase, Scopus, Web of Knowledge, MedNar, and ProQuest Theses and Dissertations were searched from the inception of the database until June 2012 for any quantitative studies that examined the association between periodontal disease and rheumatoid arthritis. Nineteen studies met our inclusion criteria. Good evidence was found to support an association between these conditions with regard to tooth loss, clinical attachment levels, and erythrocyte sedimentation rates. Moderate evidence was noted for C-reactive protein and interleukin-1β. Some evidence for a positive outcome of periodontal treatment on the clinical features of rheumatoid arthritis was noted. These results provide moderate evidence based on biochemical markers and stronger evidence with regard to clinical parameters that common risk factors or common pathologic processes may be responsible for an association between rheumatoid arthritis and periodontal disease. Further studies are required to fully explore both the biochemical processes and clinical relationships between these 2 chronic inflammatory conditions. There is a need to move from case-control studies to more rigorous studies using well-defined populations and well-defined biochemical and clinical outcomes as the primary outcome measures with consideration of potential confounding factors.

Abstract
OBJECTIVE To profile the abundance and diversity of subgingival oral microbiota in patients with never-treated, new-onset rheumatoid arthritis (RA). METHODS Periodontal disease (PD) status, clinical activity, and sociodemographic factors were determined in patients with new-onset RA, patients with chronic RA, and healthy subjects. Multiplexed-454 pyrosequencing was used to compare the composition of subgingival microbiota and establish correlations between the presence/abundance of bacteria and disease phenotypes. Anti-Porphyromonas gingivalis antibody testing was performed to assess prior exposure to the bacterial pathogen P gingivalis. RESULTS The more advanced forms of periodontitis were already present at disease onset in patients with new-onset RA. The subgingival microbiota observed in patients with new-onset RA was distinct from that found in healthy controls. In most cases, however, these microbial differences could be attributed to the severity of PD and were not inherent to RA. The presence and abundance of P gingivalis were also directly associated with the severity of PD and were not unique to RA. The presence of P gingivalis was not correlated with anti-citrullinated protein antibody (ACPA) titers. Overall exposure to P gingivalis was similar between patients with new-onset RA and controls, observed in 78% of patients and 83% of controls. The presence and abundance of Anaeroglobus geminatus correlated with the presence of ACPAs/rheumatoid factor. Prevotella and Leptotrichia species were the only characteristic taxa observed in patients with new-onset RA irrespective of PD status. CONCLUSION Patients with new-onset RA exhibited a high prevalence of PD at disease onset, despite their young age and paucity of smoking history. The subgingival microbiota profile in patients with new-onset RA was similar to that in patients with chronic RA and healthy subjects whose PD was of comparable severity. Although colonization with P gingivalis correlated with the severity of PD, overall exposure to P gingivalis was similar among the groups. The role of A geminatus and Prevotella/Leptotrichia species in this process merits further study.

Abstract
OBJECTIVES Our aim was to establish whether alcohol protects against RA development and to determine whether this effect is influenced by alcohol dose, duration and serological status through systematically reviewing the literature and undertaking a meta-analysis. METHODS We searched Medline/EMBASE (1946 to July 2012) using the terms rheumatoid arthritis.mp or arthritis, rheumatoid/ and alcohol.mp or ethanol/. Manuscript bibliographies were reviewed. Observational studies were included that were case-control/cohort, examined the relationship between alcohol and RA risk and reported or allowed the calculation of effect size data [odds ratios (ORs)/relative risks (RRs) with 95% CIs] in drinkers vs non-drinkers. A random-effects model was used to estimate pooled ORs/RRs. Dose-risk relationships were evaluated by trend tests. RESULTS. Nine studies (from 893 articles) met our inclusion criteria, comprising six case-control (3564 cases; 8477 controls) and three cohort studies (444 RA cases; 84 421 individuals). A significant protective effect of alcohol on RA risk was observed-summary OR for RA in drinkers vs non-drinkers 0.78 (95% CI 0.63, 0.96). This effect was confined to ACPA-positive RA-summary OR 0.52 (95% CI 0.36, 0.76), with no significant risk reduction seen for ACPA-negative RA-summary OR 0.74 (95% CI 0.53, 1.05). Subgroup analysis by study design identified a significant relationship in case-control but not cohort studies. CONCLUSION Alcohol intake is inversely associated with ACPA-positive RA, suggesting a protective effect. As this finding is confined to case-control studies further research is required with prospective cohort studies incorporating ACPA status to confirm this relationship.

Abstract
Objective: To assess and compare the oral hygiene and periodontal status among children with Poliomyelitis having upper limb disability, lower limb disability and both upper and lower disability at Udaipur city, Rajasthan, India.
Study design: Total sample comprised of 344 Poliomyelitis children (upper limb disability: 33.4%; lower limb disability: 33.7%; both upper and lower limb disability: 32.9%) in the age group of 12-15 years. Clinical examination included recording Simplified Oral Hygiene Index and Community Periodontal Index. Analysis of variance (ANOVA), multiple logistic and stepwise linear regression were used for statistical analysis.
Results: The mean OHI-S (2.52±1.05) score was found to be highest among children who had both upper and lower limb disability (p<0.05). The highest and lowest mean number of healthy sextants were found among those with only lower limb disability (4.53±2.05) and among those with both upper and lower limb disability (0.77±1.39), respectively (p<0.05). Stepwise multiple linear and multiple logistic regression analysis showed that the best predictor for oral hygiene and periodontal status was limb involved in the disability.
Conclusion: The results of the study depicted an overall poor oral hygiene and periodontal status of the group. It was recognized that limbs involved in the disability had an impact on the oral hygiene and periodontal condition. The situation in this specialized population draws immediate attention for an integrated approach in improving the oral health and focus towards extensive research.
Key words:Poliomyelitis, upper limb disability, lower limb disability, oral hygiene, periodontal status.

Abstract
BACKGROUND Patients with rheumatoid arthritis (RA) may have more prevalent and severe periodontitis than healthy controls. Periodontitis may increase the systemic inflammation in RA. The aim of this study is to assess periodontitis prevalence and severity and its potential association with systemic inflammation in Indonesian patients with RA. METHODS A full-mouth periodontal examination including probing depth, gingival recession, plaque index, and bleeding on probing was performed in 75 Indonesians with RA and 75 age-, sex-, and smoking-matched Indonesian controls. A validated questionnaire was used to assess smoking, body mass index, education, and medical conditions. In addition, in all participants, the use of drugs was noted, and erythrocyte sedimentation rates and serum levels of high-sensitivity C-reactive protein (hsCRP), rheumatoid factor, and anti-citrullinated protein antibodies were measured. Differences in periodontitis prevalence and 12 measures of periodontitis severity between patients with RA and controls were analyzed using univariate analyses. RESULTS No significant differences in periodontitis prevalence and 11 measures of periodontitis severity between patients with RA and controls were observed. Conversely, patients with RA had a significantly lower surface area of healthy pocket epithelium versus controls (P = 0.008), and a tendency toward higher hsCRP levels was observed in patients with RA with severe periodontitis compared with patients with RA with no mild or moderate periodontitis (P = 0.063). It has to be noted that all patients with RA were on anti-inflammatory drugs, whereas none of the controls used such drugs. CONCLUSION Prevalence and severity of periodontitis in Indonesian patients with RA is comparable to controls but with less healthy pocket epithelium than in controls and a tendency toward a higher inflammatory state in patients with RA and severe periodontitis.

Abstract
Introduction The association between rheumatoid arthritis (RA) and periodontitis is suggested to be linked to the periodontal pathogen Porphyromonas gingivalis. Colonization of P. gingivalis in the oral cavity of RA patients has been scarcely considered. To further explore whether the association between periodontitis and RA is dependent on P. gingivalis, we compared host immune responses in RA patients with and without periodontitis in relation to presence of cultivable P. gingivalis in subgingival plaque. Methods In 95 RA patients, the periodontal condition was examined using the Dutch Periodontal Screening Index for treatment needs. Subgingival plaque samples were tested for presence of P. gingivalis by anaerobic culture technique. IgA, IgG and IgM antibody titers to P. gingivalis were measured by ELISA. Serum and subgingival plaque measures were compared to a matched control group of non-RA subjects. Results A higher prevalence of severe periodontitis was observed in RA patients in comparison to matched non-RA controls (27% versus 12%, p < 0.001). RA patients with severe periodontitis had higher DAS28 scores than RA patients with no or moderate periodontitis (p < 0.001), while no differences were seen in IgM-RF or ACPA reactivity. Furthermore, RA patients with severe periodontitis had higher IgG- and IgM-anti P. gingivalis titers than non-RA controls with severe periodontitis (p < 0.01 resp. p < 0.05), although subgingival occurrence of P. gingivalis was not different. Conclusions Severity of periodontitis is related to severity of RA. RA patients with severe periodontitis have a more robust antibody response against P. gingivalis than non-RA controls, but not all RA patients have cultivable P. gingivalis.

Abstract
OBJECTIVE To investigate the association between the risk of rheumatoid arthritis (RA) and a history of periodontitis. METHODS This nationwide, population-based, case-control study used administrative data to identify 13 779 newly diagnosed patients with RA (age ≥16 years) as the study group and 137 790 non-patients with RA matched for age, sex, and initial diagnosis date (index date) as controls. Using conditional logistic regression analysis after adjustment for potential confounders, including geographical region and a history of diabetes and Sjögren's syndrome, ORs with 95% CI were calculated to quantify the association between RA and periodontitis. To evaluate the effects of periodontitis severity and the lag time since the last periodontitis visit on RA development, ORs were calculated for subgroups of patients with periodontitis according to the number of visits, cumulative cost, periodontal surgery and time interval between the last periodontitis-related visit and the index date. RESULTS An association was found between a history of periodontitis and newly diagnosed RA (OR=1.16; 95% CI 1.13 to 1.21). The strength of this association remained statistically significant after adjustment for potential confounders (OR=1.16; 95% CI 1.12 to 1.20), and after variation of periodontitis definitions. The association was dose- and time-dependent and was strongest when the interval between the last periodontitis-related visit and the index date was <3 months (OR=1.64; 95% CI 1.49 to 1.79). CONCLUSIONS This study demonstrates an association between periodontitis and incident RA. This association is weak and limited to lack of individual smoking status.
