Oral manifestations associated with inflammatory bowel disease and early endoscopic findings in patients with spondyloarthritis.

BACKGROUND AND AIMS: Spondyloarthritis (SpA) is a group of autoinflammatory disorders, of which the primary extra-articular manifestation is inflammatory bowel disease (IBD). The oral cavity being a part of gastrointestinal tract, is significantly compromised in IBD, and in many cases, it is the first site of clinical manifestations of IBD. This study aimed to identify changes in the oral mucosa associated with the onset of IBD and their association with endoscopic/histological findings. MATERIALS AND METHODS: The study assessed 80 patients with SpA and 52 healthy controls. Oral, rheumatological, and gastroenterological assessments were performed. The ileocolonoscopy was performed via digital magnification chromoendoscopy. The statistical analysis consisted of Chi-square, Fisher's exact, and multiple correspondence discriminant analysis tests. RESULTS: From the disease cohort, 63.0% patients showed oral lesions (p = 0.050). These manifestations ranged from gingivitis (55.0%, p = 0.001), aphthous stomatitis (3.8%, p = 0.091), angular cheilitis (2.6%, p = 0.200), and perioral erythema with scaling (1.3%, p = 0.300). All patients who presented with alterations in colonic mucosa also had oral lesions associated with IBD (p = 0.039), specifically gingivitis/aphthous stomatitis (p = 0.029). CONCLUSION: The patients with SpA without IBD present significant oral signs and symptoms. Gingivitis seems to be the most relevant because of its associations with early endoscopic and histological findings. CLINICAL RELEVANCE: An integral approach to the diagnostic tests that includes evaluations of oral, rheumatological and gastroenterological tissues may favor timely attention and improve patients' quality of life.

Association of Dickkopf-1 Polymorphisms With Radiological Damage and Periodontal Disease in Patients With Early Rheumatoid Arthritis: A Cross-Sectional Study.

BACKGROUND: Rheumatoid arthritis (RA) is a systemic autoimmune disease that increased bone resorption. Periodontal disease (PD) is an associated risk factor of RA. Studies suggest an association between bone markers such as the dickkopf-related protein 1 (DKK-1) and progression of radiological damage. We aimed to evaluate the marker DKK-1, its polymorphisms in patients with early rheumatoid arthritis (eRA), and its association with rheumatic, radiological, and periodontal variables. METHODS: This is a cross-sectional study. Samples were obtained from 63 patients with eRA. Radiographs of hands and feet were evaluated by Sharp-van der Heijde score (SHS) and Simple Erosion Narrowing Score (SENS). Serum DKK-1 levels and high-resolution fusion analysis was used for polymorphisms (rs1896368, rs1896367, rs1528873). Bivariate analyses were performed. RESULTS: Individuals heterozygous for rs1896367 had more frequent erosions (p = 0.026) and joint space narrowing (p = 0.005) in the feet, higher SHS (p = 0.016), and higher SENS (p ≤ 0.001). Patients homozygous for rs1896368 had less frequent joint space narrowing in hands and feet as assessed by SHS and less presence of erosions by SENS (odds ratio, 0.04; 95% confidence interval, 0.00-0.93; p < 0.05). The presence of PD was associated with the homozygous of rs1896367 (p = 0.009) and the heterozygous of rs1896368 (p = 0.033). CONCLUSIONS: Polymorphism rs1896367 seems to be associated with greater radiological compromise; rs1896368 confers protection against bone damage in Colombian eRA patients.

Predictive factors related to the progression of periodontal disease in patients with early rheumatoid arthritis: a cohort study.

BACKGROUND: Rheumatoid arthritis (RA) and periodontal disease are inter-related conditions. However, factors predictive of periodontal disease progression in patients with early rheumatoid arthritis (eRA) are lacking. The aim of this study was to identify factors associated with the progression of clinical attachment loss (CAL) in interproximal dental sites of eRA patients. METHODS: Twenty-eight eRA patients were evaluated for the progression of CAL at 280 interproximal dental sites at 1 year of follow-up. Markers of RA activity (rheumatoid factor, erythrocyte sedimentation rate, and C-reactive protein), a marker of bone resorption (Dickkopf-related protein 1), Disease Activity Score 28 and Simple Disease Activity Index were included as potential systemic predictive factors. Plaque index, gingival index, pocket depth, clinical attachment level and Dickkopf-related protein 1 in crevicular fluid at baseline were included as potential local predictive factors. Data were analysed in a hierarchical structure using generalised linear mixed models for progression at each site (> 2 mm) during follow-up. RESULTS: C-reactive protein level was the most important predictive systemic factor for the progression of CAL. The mean CAL and a high degree of gingival inflammation in interproximal sites at baseline were important predictive local factors (p <  0.0001). Patients who received combined treatment with disease-modifying antirheumatic drugs and corticosteroids exhibited less CAL (p <  0.0001). The predictive value of the generalised linear mixed model for progression was 85%. CONCLUSIONS: Systemic factors, including RA disease activity and baseline periodontal condition, were associated with periodontal progression. Pharmacological treatment may affect periodontal progression in patients with early RA.

The Interaction Effect of Anti-RgpA and Anti-PPAD Antibody Titers: An Indicator for Rheumatoid Arthritis Diagnosis.

Porphyromonas gingivalis secretes virulence factors like Arg-gingipains and peptidyl arginine deiminase (PPAD), that are associated with rheumatoid arthritis (RA) pathogenesis. However, there is no information regarding the antibody titers for these bacterial enzymes as systemic indicators or biomarkers in RA. In this cross-sectional study, 255 individuals were evaluated: 143 were diagnosed with RA, and 112 were without RA. Logistic regression models adjusted for age, sex, basal metabolic index, smoking, and periodontitis severity were used to evaluate the association of RA with rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPAs), erythrocyte sedimentation rate, high sensitivity C-reactive protein, anti-RgpA, anti-PPAD, and double positive anti-RgpA/anti-PPAD. It was found that RF (odds ratio [OR] 10.6; 95% confidence interval [CI] 4.4-25), ACPAs (OR 13.7; 95% CI 5.1-35), and anti-RgpA/anti-PPAD double positivity (OR 6.63; 95% CI 1.61-27) were associated with RA diagnoses. Anti-RgpA was also associated with RA (OR 4.09; 95% CI 1.2-13.9). The combination of anti-RgpA/anti-PPAD showed a high specificity of 93.7% and 82.5% PPV in identifying individuals with RA. RgpA antibodies were associated with the periodontal inflammatory index in RA individuals (p < 0.05). The double positivity of the anti-RgpA/anti-PPAD antibodies enhanced the diagnosis of RA. Therefore, RgpA antibodies and anti-RgpA/anti-PPAD may be biomarkers for RA.

High Levels of Leptin and Adipsin Are Associated with Clinical Activity in Early Rheumatoid Arthritis Patients with Overweight and Periodontal Infection.

Adipokines are associated with the pathogenesis of rheumatoid arthritis (RA) and are potential biomarkers of disease activity, periodontitis, and obesity. The aim of this was to establish the association between adipokine profile, RA disease activity, body mass index, and periodontal infection. This study evaluated 51 patients with early-RA and 51 controls including serum rheumatological markers, adipokine levels, detection of Porphyromonas gingivalis and serum anti-Porphyromonas gingivalis antibodies, clinical and periodontal measurements. Statistical analyses were run with SPSS® V26, with a logistic regression model to confirm associations. The results show high levels of leptin were more frequent in patients (p = 0.001) who simultaneously showed a higher frequency of Porphyromonas gingivalis (p = 0.004). Patients with concomitant presence of Porphyromonas gingivalis, high clinical activity score, and overweight were correlated with high levels of leptin (OR, 7.20; 95% CI, 2.68-19.33; p = 0.0001) and adipsin (OR, 2.69; 95% CI, 1.00-7.28; p = 0.005). The conclusion is that high levels of leptin and adipsin are associated with greater clinical activity in early-RA patients with overweight and periodontal infection, whereby overweight and Porphyromonas gingivalis may enhance RA activity. This may represent a pathological mechanism between these conditions, where adipokines seem to have a key role.

Implementation of screening criteria for inflammatory bowel disease in patients with spondyloarthritis and its association with disease and endoscopic activity.

There is little literature on the implementation of screening criteria for inflammatory bowel disease (IBD) in patients with spondyloarthritis (SpA). This study aimed to apply IBD screening criteria in a group of patients with SpA without IBD diagnosis and correlate them to endoscopic findings and disease activity. A total of 82 patients with SpA were included. The IBD screening test and ileocolonoscopy with digital chromoendoscopy with magnification and histological analysis were performed. The data were analysed with Chi-square test/Fisher's exact test and multiple correspondence analysis. The major screening criteria found in 48.7% of the patients were associated with a history of infection (p = 0.037). Rectal bleeding was associated with the diagnosis of ankylosing spondylitis, acute inflammation, enthesitis and tissue architecture alteration in the ileum (p < 0.050). Diarrhoea was associated with a higher disease activity score (p = 0.02). Minor screening criteria were associated with painful inflammatory joint (p = 0.05), high disease activity score (p = 0.001) and high calprotectin levels (p = 0.050). Abdominal pain (36.9%) was associated with axial/peripheral compromise (p = 0.017), inflammatory back pain (p = 0.01), enthesitis (p = 0.021), higher disease activity score (p = 0.023) and acute ileum inflammation (p = 0.046). Diarrhoea of 4 weeks and abdominal pain were the most prevalent major and minor screening criteria, respectively, being related to early manifestations of inflammatory bowel compromise and higher disease activity score. This screening test grants a chance of opportune referral of SpA patients from rheumatology to gastroenterology.

Lower Levels of Vitamin D Associated with Disease Activity in Colombian Patients with Systemic Lupus Erythematosus.

BACKGROUND: Systemic Lupus Erythematosus (SLE) involves genetic, environmental, and hormonal alterations, including Vitamin D deficiency. OBJECTIVE: To evaluate the association between vitamin D levels with anti-dsDNA, complement proteins, immunoglobulins levels and disease activity scores. METHODS: A cross-sectional study was performed. The levels of 25-OH vitamin D were measured in patients older than 18 years with SLE according to ACR/97 [American College of Rheumatology 1997] from 2013 to 2015. The association was assessed by Mann-Whitney U and Kruskal Wallis tests for continuous variables, and by the Chi or Fisher exact test for the nominal variables. RESULTS: Sixty-nine patients were included; 82% were women; the mean age was 38.5 years; 36.2% had low levels of vitamin D with higher consumption [p=0.006] of C4 and C3 complement proteins, plus higher levels of anti-dsDNA. Lower values of vitamin D were observed in patients with moderate to severe activity [p=0.0001] by SLEDAI [Systemic Lupus Erythematosus Activity Index] and general domain [p=0.039] and renal domain [p=0.009] by BILAG [British Isles Lupus Assessment Group] 2004. The mean vitamin D levels were higher in the group not receiving steroids when compared to those groups with dosages of 0.5-1mg/kg/d [p=0.048]. CONCLUSION: Lower levels of vitamin D are associated with greater complement protein consumption and higher disease activity rates. Therefore, it is important to evaluate vitamin D supplementation in patients with SLE as part of the treatment, especially when it includes the use of steroids.
