BackgroundA high prevalence of periodontitis has been reported in rheumatoid arthritis (RA) patients, although the strength of this association, its temporal link and the possible relationship between the severity of periodontitis and RA disease activity remain unclear. The objective of this work was to investigate whether periodontitis is associated with RA and whether periodontitis severity is linked to RA disease activity.MethodsThis case–control study included 187 patients diagnosed with RA and 157 control patients without inflammatory joint disease. RA disease activity and severity were evaluated by the Disease Activity Score 28, the Simplified Disease Activity Index, the Clinical Disease Activity Index, rheumatoid factor, anti-citrullinated protein antibody titers, the erythrocyte sedimentation rate, C-reactive protein, presence of extra-articular manifestations and type of RA therapy. Exposure severity was assessed by the following periodontal parameters: plaque index, bleeding on probing, probing pocket depth and clinical attachment levels. Sociodemographic variables and comorbidities were evaluated as confounding variables. Outcome and exposure variables were compared by both parametric and nonparametric tests, and possible associations were assessed through regression analysis with a calculation for the adjusted odds ratio (OR).ResultsA significant association was demonstrated between periodontitis and RA with an adjusted OR of 20.57 (95% CI 6.02–70.27, p < 0.001). Compared with controls, all parameters related to periodontal status (plaque index, bleeding on probing, probing pocket depth and clinical attachment levels) were significantly worse in RA patients (p < 0.001). Periodontitis severity was significantly associated with RA disease activity (p < 0.001), showing in an ordinal logistic regression model an association between periodontal severity and disease activity with an adjusted OR of 2.66 (95% CI 1.24–5.74, p = 0.012).ConclusionA significant association was demonstrated between periodontitis and RA, independent of other confounders. This association was more evident in patients with pronounced periodontal disease and higher RA disease activity.Electronic supplementary materialThe online version of this article (10.1186/s13075-019-1808-z) contains supplementary material, which is available to authorized users.

Background: Given the importance of primary care to healthcare systems and population health, it seems crucial to identify factors that contribute to the quality of primary care. Professional satisfaction has been linked with quality of primary care. Physician dissatisfaction is considered a risk factor for burnout and leaving medicine.Objectives: This study explored factors associated with professional satisfaction in seven European countries.Methods: A survey was conducted among primary care physicians. Estonia, Finland, Germany and Hungary used a web-based survey, Italy and Lithuania a telephone survey, and Spain face to face interviews. Sociodemographic information (age, sex), professional experience and qualifications (years since graduation, years of experience in general practice), organizational variables related to primary care systems and satisfaction were included in the final version of the questionnaire. A logistic regression analysis was performed to assess the factors associated with satisfaction among physicians.Results: A total of 1331 primary care physicians working in primary care services responded to the survey. More than half of the participants were satisfied with their work in primary care services (68.6%). We found significant associations between satisfaction and years of experience (OR = 1.01), integrated network of primary care centres (OR = 2.8), patients having direct access to specialists (OR = 1.3) and professionals having access to data on patient satisfaction (OR = 1.3). Public practice, rather than private practice, was associated with lower primary care professional satisfaction (OR = 0.8).Conclusion: Elements related to the structure of primary care are associated with professional satisfaction. At the individual level, years of experience seems to be associated with higher professional satisfaction.

BackgroundThe purpose of this study was to assess the prevalence, associated factors, and impact on mortality of primary respiratory disease in a large systemic lupus erythematosus (SLE) retrospective cohort.MethodsAll adult patients in the RELESSER-TRANS (Registry of Systemic Lupus Erythematosus Patients of the Spanish Society of Rheumatology [SER], cross-sectional phase) registry were retrospectively investigated for the presence of primary pleuropulmonary manifestations.ResultsIn total 3215 patients were included. At least one pleuropulmonary manifestation was present in 31% of patients. The most common manifestation was pleural disease (21%), followed by lupus pneumonitis (3.6%), pulmonary thromboembolism (2.9%), primary pulmonary hypertension (2.4%), diffuse interstitial lung disease (2%), alveolar hemorrhage (0.8%), and shrinking lung syndrome (0.8%).In the multivariable analysis, the variables associated with the development of pleuropulmonary manifestation were older age at disease onset (odds ratio (OR) 1.03, 95% confidence interval (CI) 1.02–1.04), higher SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) scores (OR 1.03, 95% CI 1.00–1.07), the presence of Raynaud’s phenomenon (OR 1.41, 95% CI 1.09–1.84), secondary antiphospholipid syndrome (OR 2.20, 95% CI 1.63–2.97), and the previous or concomitant occurrence of severe lupus nephritis, (OR 1.48, 95% CI 1.12–1.95) neuropsychiatric manifestations (OR 1.49, 95% CI 1.11–2.02), non-ischemic cardiac disease (OR 2.91, 95% CI 1.90–4.15), vasculitis (OR 1.81, 95% CI 1.25–2.62), hematological manifestations (OR 1.31, 95% CI 1.00–1.71), and gastrointestinal manifestations, excluding hepatitis (OR 2.05, 95% CI 1.14–3.66). Anti-RNP positivity had a clear tendency to significance (OR 1.32, 95% CI 1.00–1.75; P = 0.054).The development of pleuropulmonary manifestations independently contributes to a diminished survival (hazard ratio of 3.13). However, not all complications will influence the prognosis in the same way. Whereas the occurrence of pleural disease or pulmonary thromboembolism has a minimal impact on the survival of these patients, the remaining manifestations have a major impact on mortality.ConclusionExcept for pleural disease, the remaining respiratory manifestations are very uncommon in SLE (<4%). Pleuropulmonary manifestations independently contributed to a decreased survival in these patients.Electronic supplementary materialThe online version of this article (10.1186/s13075-018-1776-8) contains supplementary material, which is available to authorized users.

The retention rate of a biological drug (percentage of patients remaining on treatment over time) provides an index of a drug's overall effectiveness. The golimumab retention rate as first-line biological therapy was high in clinical trial extensions lasting 5 years. Real-world studies also indicate good retention rates but have been of shorter duration. The probability of retention with golimumab treatment was assessed, as any line of anti-tumor necrosis factor-alpha therapy, for up to 5 years in patients with rheumatoid arthritis (RA), axial spondyloarthritis (SpA) or psoriatic arthritis (PsA), associated factors were analyzed. A retrospective database analysis of the Spanish registry of patients with rheumatic disorders receiving biological drugs (BIOBADASER) was performed. Among 353 patients, 29.8% had RA, 41.6% SpA and 28.6% PsA. Golimumab was the first biological drug in 40.1% of patients, second in 30.1% and third/later in 29.8%. The overall probability of retention of golimumab at years 1, 2, 3, 4 and 5 was 85.9% (95% confidence interval 81.4-89.5%), 73.7% (67.1-79.1%), 68.5% (60.5-75.1%), 60.6% (50.2-69.5%) and 57.1% (44.9-67.5%), respectively. Retention was similar across indications (p = 0.070) but was greater when golimumab was used as the first biological agent compared with later therapy lines (p < 0.001). Factors associated with higher retention of golimumab treatment (Cox regression) were use as a first-line biological and concomitant methotrexate treatment; corticosteroid need was associated with lower retention. The long-term probability of golimumab retention was high in this real-world study of patients with rheumatic diseases, especially when used as the first biological drug.
