Abstract Background Subgingival microbiome in disease-associated subgingival sites is known to be dysbiotic and significantly altered. In patients with rheumatoid arthritis (RA), the extent of dysbiosis in disease- and health-associated subgingival sites is not clear. Methods 8 RA and 10 non-RA subjects were recruited for this pilot study. All subjects received full oral examination and underwent collection of subgingival plaque samples from both shallow (periodontal health-associated, probing depth ≤ 3mm) and deep subgingival sites (periodontal disease-associated, probing depth ≥ 4 mm). RA subjects also had rheumatological evaluation. Plaque community profiles were analyzed using 16 S rRNA sequencing. Results The phylogenetic diversity of microbial communities in both RA and non-RA controls was significantly higher in deep subgingival sites compared to shallow sites (p = 0.022), and the overall subgingival microbiome clustered primarily according to probing depth (i.e. shallow versus deep sites), and not separated by RA status. While a large number of differentially abundant taxa and gene functions was observed between deep and shallow sites as expected in non-RA controls, we found very few differentially abundant taxa and gene functions between deep and shallow sites in RA subjects. In addition, compared to non-RA controls, the UniFrac distances between deep and shallow sites in RA subjects were smaller, suggesting increased similarity between deep and shallow subgingival microbiome in RA. Streptococcus parasanguinis and Actinomyces meyeri were overabundant in RA subjects, while Gemella morbillorum, Kingella denitrificans, Prevotella melaninogenica and Leptotrichia spp. were more abundant in non-RA subjects. Conclusions The aggregate subgingival microbiome was not significantly different between individuals with and without rheumatoid arthritis. Although the differences in the overall subgingival microbiome was driven primarily by probing depth, in contrast to the substantial microbiome differences typically seen between deep and shallow sites in non-RA patients, the microbiome of deep and shallow sites in RA patients were more similar to each other. These results suggest that factors associated with RA may modulate the ecology of subgingival microbiome and its relationship to periodontal disease, the basis of which remains unknown but warrants further investigation.

Abstract The aim of this study was to assess the prevalence of periodontal disease and the effect of periodontal treatment in patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA). Forty-four RA patients, thirty SpA patients and thirty-nine healthy volunteers were recruited to the study. Periodontal examination included the approximal plaque index (API), bleeding on probing (BoP), probing depth (PD) and number of teeth. Samples from the deepest periodontal pockets were taken for the detection of Porphyromonas gingivalis DNA with the use of the polymerase chain reaction. All subjects with periodontitis, who completed the study, received periodontal treatment consisting of scaling/root planing and oral hygiene instructions. Disease activity scores, clinical and laboratory parameters were assessed before and 4–6 weeks after periodontal treatment. No significant difference in the prevalence of periodontal disease and the presence of P. gingivalis DNA were found in RA and SpA patients compared to healthy controls. Significantly higher API (80% vs 63%; p = 0.01) and a lower number of teeth (20 vs 25, p = 0.001) were found in RA patients. BoP was significantly elevated in SpA patients (51% vs 33%, p = 0.02). Disease activity measured by the DAS28(CRP) was significantly reduced in RA patients after periodontal treatment (p = 0.002). Clinical and biochemical parameters were not improved in SpA patients. Nonsurgical periodontal treatment had an impact on the decrease in RA activity. Periodontal examination is necessary in patients with RA to detect and treat periodontitis at an early stage.

Introduction: Rates of periodontal disease and tooth loss are increased in individuals with rheumatoid arthritis (RA). Understanding factors that contribute to the increased burden of periodontal disease in RA is critical to improving oral health and arthritis outcomes. Objectives: To determine the perceptions held by people with RA relating to their oral health, to identify patient-centered priorities for oral health research, and to inform optimal strategies for delivering oral health knowledge. Methods: Semistructured interviews were conducted with patients with RA. Recorded interview transcripts were iteratively reviewed to reveal surface and latent meaning and to code for themes. Constructs were considered saturated when no new themes were identified in subsequent interviews. We report themes with representative quotes. Results: Interviews were conducted with 11 individuals with RA (10 women [91%]; mean age, 68 y), all of whom were taking RA medication. Interviews averaged 19 min (range, 8 to 31 min) and were mostly conducted face-to-face. Three overall themes were identified: 1) knowledge about arthritis and oral health links; 2) oral health care in RA is complicated, both in personal hygiene practices and in professional oral care; and 3) poor oral health is a source of shame. Participants preferred to receive oral health education from their rheumatologists or dentists. Conclusions: People with RA have unique oral health perceptions and experience significant challenges with oral health care due to their arthritis. Adapting oral hygiene recommendations and professional oral care delivery to the needs of those with arthritis are patient priorities and are required to improve satisfaction regarding their oral health. Knowledge Translation Statement: Patients living with long-standing rheumatoid arthritis described poor oral health–related quality of life and multiple challenges with maintaining optimal oral health. Study findings indicate a need for educational materials addressing oral health maintenance for patients with rheumatic diseases and their providers.

Background:Periodontal disease (PD) has been widely studied in the pathogenesis of rheumatoid arthritis (RA). As well, its relationship with severity and disease activity, has also been investigated with ambiguous results. It has been suggested that the improvement of oral health could enhance disease activity scores.1 PD prevalence worldwide stands around 60% in older adults (>65 years) and its frequency increases with aging.2Objectives:To asses oral health in RA patients and to identify predictors of PD in this population.Methods:Patients diagnosed of RA at treatment with biological, classical or targeted synthetic disease modifying anti-rheumatic drugs (b/cs/tsDMARDs) in the aforementioned hospital during 2020 performed a dental review with a specialized periodontal odontologist. Oral health patterns were given for all patients, following criteria of American Academy of Periodontology, and reevaluation of disease activity was made 2 months later.Clinical, demographic and treatment data were collected from participants.Univariable logistic regression was performed to identify predictors of PD. Variables with p<0.20 were selected for multivariable analysis.Stata 15.1 was used to perform statistical analysis.Results:81 patients were recruited. 82.72% were female. Mean age was 56.17 years (SD 14.15) and mean time since diagnosis was 15.58 years (SD 8.17). 25% were current or past smokers. 21 patients had comorbidities (arterial hypertension the most frequent). 66.67% were rheumatoid factor (RF) positive and 72.73% anti-citrullinated peptide autoantibody (ACPA) positive. Median erythrocyte sedimentation rate (ESR) was 12 mm (IQR 6;23) and mean C-reactive protein (CRP) was 0.48 mg/dl (SD 1.18). Mean disease activity score (DAS28-VSG) at the testing time was 2.62 (SD 1.21) and after 2 months was 2.39 (SD 0.97). 96.30% of patients were at treatment with csDMARDs, 64.20% with glucocorticoids, 96.30% with bDMARDs and 6 patients with tsDMARDs.Univariable analysis identified higher age, at least one autoantibody positive and ESR/CRP as potential predictors of medium/severe PD (p<0.20). Multivariable testing including these variables pointed out higher age, lower ESR and at least one autoantibody positive (OR 1.09 [CI95% 1.04-1.14] p=0.001, OR 0.18 [CI95% 0.04-0.95] p=0.044 and OR 0.94 [CI95% 0.88-1.00] p=0.042, respectively) as predictors of medium or severe PD (≥3 mm interdental clinical attachment loss).Univariable analysis identified higher age, the presence of any comorbidity and anti tumour-necrosis factor alpha treatment (anti-TNF) as potential predictors of severe PD (p<0.20). Multivariable testing including these variables pointed out higher age (OR 1.15 [CI95%1.02-1.30] p=0.026) as predictor of severe PD (≥5 mm interdental clinical attachment loss).Conclusion:Periodontal disease is still an extended health problem among the entire population. Its prevalence in RA is increased, therefore higher age and RF or ACPA positive are risk factors for developing severe PD. This analysis might suggest that an aggressive management of PD could implement better responses in DAS28. Also anti-TNF treatment could delimit a “penumbra” group of patients at risk of developing severe PD, where intensive manage could modify the final outcome.References:[1]C O Bingham, M Moni.

Background:Idiopathic juvenile arthritis (JIA) is a heterogeneous group of pathologies whose origin remains unknown at present (1). They are characterised by a systemic inflammatory and joint disease affecting children under 16 years of age. The current classification groups the different forms of JIA into 7 distinct entities (systemic forms, polyarticular forms with or without rheumatoid factors, oligoarticular forms, inflammatory arthritis associated with enthesopathies (ERA), arthritis associated with psoriasis and unclassifiable arthritis). Exact etiology of JIA is still unknown. To date, the various hypotheses put forward on the occurrence of JIAs integrate the genetic and environmental framework.The link between periodontal disease and rheumatoid arthritis (RA) is largely reported. Recently, Porphyromonas gingivalis (P. gingivalis) infection explained the occurrence of arthritis in rodent and in RA (2). Several studies mention the beneficial effect of P. gingivalis treatment on disease activity.Currently, there are very few studies on the prevalence of P. gingivalis in patients with JIA and the possible involvement of the germ in the development of inflammatory joint diseases in the pediatric population(3)(4).Objectives:The objective of our study is to determine presence of high IgG antibodies against P. gingivalis and Prevotella Intermedia in a cohort of patients with JIA compared to a control population and to determine variation of level according to sub-classes of JIA.Methods:Sera were obtained from 101 patients satisfying the ILAR classification criteria for JIA and in 25 patients with two other dysimmune disorders (type 1 diabetes and juvenile inflammatory bowel disease). Level of IgG antibodies against P. gingivalis and Prevotella Intermedia were obtained by homemade ELISA already used previously (5).Results:In the JIA group, major children were oligarthritis (47.5%), polyarthritis represents 31.7% of JIAs, ERA and systemic forms of JIA are respectively 9 and 11%. For the control group, 10 (40%) children had diabetes and 15 (60%) had IBD.Levels of anti-P. gingivalis anti-Prevotella Intermedia antibodies were higher in AJI group compared at control groups (P<0.01, P<0.05). Theses difference are mainly related to oligoarthritis and ERA subsets for both P. gingivalis and Prevotella Intermedia.Figure 1.Relative titer of antibodies to P. gingivalis and anti Prevotella intermedia. *: P<0.05; **: P<0.01; ***: P<0.001. P. gingivalis (control vs oligoarthritis p= 0.0032. control vs ERA p= 0.0092). Prevotella intermedia (control vs oligoarthritis p= 0.0194. control vs ERA p= 0.0039).Conclusion:We confirmed high level of anti-P. gingivalis and anti-Prevotella intermedia antibodies in JIA compared to other inflammatory disorders. For the first time, we observed that this high level was mainly in oligoarthritis and ERA. Further investigations are required to investigate involvement of oral dysbiosis in AJI pathogenesis. As observed in RA, it could be a new way to integrate in JIA therapy management.References:[1]Thatayatikom A, De Leucio A. Juvenile Idiopathic Arthritis (JIA).

Background:Rates of periodontal disease and tooth loss are increased in rheumatoid arthritis (RA). Periodontal disease may exacerbate RA inflammation and complicate RA care. Understanding factors that contribute to the increased burden of periodontal disease in RA is critical to improving oral health and possibly arthritis outcomes. People with RA may have unique needs and/or barriers to maintain oral health.Objectives:To determine from people with RA what are their experiences and perceptions about their oral health, their most important questions relating to oral health, and how they wish to receive oral health information.Methods:Semi-structured interviews were conducted with RA patients. Recorded interview transcripts underwent iterative content analysis. Transcripts were initially reviewed to develop a coding guide. Latent content, or larger themes, were then applied to the transcripts. Constructs were considered saturated when no new themes were identified with subsequent interviews. We report identified themes with representative quotes.Results:Interviews with 11 RA (10[91%] female; all on RA medication) averaged 19 minutes (range 8-31 minutes) and were mostly conducted face-to-face. Many believed RA medication contributed to dry mouth. Most participants had not previously considered other links between oral health and RA. Themes identified included the need for complicated oral health routines, barriers of cost and access to dental care, and shame relating to oral health (Table 1). Participants preferred to receive oral health education from their rheumatologists or dentists over printed or online resources.Conclusion:RA patients have unique needs relating to oral health and report poor oral quality of life. Strategies to optimize oral health in RA may include educational tools for optimizing oral self-care appropriate for RA, and improved access to oral care professionals who are aware of the needs of arthritis patients.Disclosure of Interests:Jennifer Protudjer: None declared, Corrie Billedeau: None declared, Chrysi Stavropoulou: None declared, Anastasia Cholakis: None declared, Robert Schroth: None declared, Carol Hitchon Grant/research support from: UCB Canada; Pfizer Canada
