Correlations between rheumatoid arthritis severity and thyroid dysfunction: insights from a cohort study on treatment patterns and hypothyroidism prevalence

Thyroid dysfunction may exacerbate the systemic inflammatory condition known as rheumatoid arthritis (RA). In this cross-sectional study, 53 patients' thyroid function tests (Thyroid-Stimulating Hormone (TSH), Free T4, Free T3) and RA activity scores (including the Health Assessment Questionnaire (HAQ) and Disease Activity Score-28 (DAS28)) were correlated with lifestyle variables including smoking, alcohol consumption, and physical activity. Results indicate that TSH levels and RA severity are strongly positively correlated (correlation coefficients: 0.85 for HAQ and 0.89 for DAS28); on the other hand, levels of Free T4 and Free T3 were negatively correlated with RA severity. With just one case of overt hypothyroidism, the bulk of the sample (87%) received a diagnosis of hypothyroidism, most of it subclinical. These results emphasize the need of include thyroid function monitoring into RA treatment plans and imply that lifestyle variables as well as thyroid hormone levels should be taken into account in the all-encompassing care of RA patients.

Associations between Rheumatoid Arthritis and Various Comorbid Conditions in Germany—A Retrospective Cohort Study

Aims: The aim of the present study was to estimate the prevalence of physical and mental health comorbidities in patients with rheumatoid arthritis (RA) in Germany, in order to better understand the complex clinical picture and its consequences. Methods: This retrospective cohort study was based on data from the IQVIA Disease Analyzer database and included individuals aged ≥ 16 years with an initial documented diagnosis of RA between 2015 and 2021 (index date). RA patients were matched 1:1 with non-RA individuals using nearest neighbor propensity score matching. The study investigated associations between RA and various disorders documented within 365 days after the index date. The cumulative incidence of defined disorders was calculated for individuals with and without RA. Multivariable logistic regression models were used to study these associations. Results: Data were available for a total of 49,713 patients with and 49,713 patients without RA (mean age: 60.4 (SD: 15.5) years; 66.7% female). A significant and clinically relevant positive association was observed between RA and seven disorders: soft tissue disorders (Odds Ratio (OR): 1.47; 95% Confidence Interval (CI): 1.42–1.52), renal failure (OR: 1.36; 95% CI: 1.26–1.47), anemia (OR: 1.32; 95% CI: 1.24–1.40), liver diseases (OR: 1.32, 95% CI: 1.23–1.41), osteopathies and chondropathies (OR: 1.28; 95% CI: 1.22–1.3), diseases of the esophagus, stomach and duodenum (OR: 1.18; 95% CI: 1.14–1.22), and nutritional deficiencies (OR: 1.17; 95% CI: 1.10–1.24). Conclusions: We observed significant associations between RA and several comorbidities, which have clinical relevance for the care of RA patients not only in general practices but also in specialist settings.

Nurse-supported care versus rheumatologist-led care in patients with rheumatoid arthritis at high disease activity: A retrospective study of two Chinese centers.

The European League Against Rheumatism recommendations for the management of rheumatoid arthritis advised the involvement of clinical nurses for the management of rheumatoid arthritis. However, The European League Against Rheumatism recommendations are difficult to apply to Chinese institutes. In China, the rheumatology nursing service is not widely adopted because the feasibility and quality of rheumatology nursing service have not been confirmed in the Chinese population by the Chinese authorities. The objectives of the study were to compare 2.5 years clinical outcomes of patients of rheumatoid arthritis (6 months history) with disease activity score 28-joint count with C-reactive protein (DAS28-CRP) > 5.1 who received nurse-supported care against those of patients who received rheumatologist-led care. Patients received 30 minutes/day and 6 times/week nurse-supported care (NC cohort, n = 127) or Patients had received 20 minutes session at every 3 months of conventional outpatient-based rheumatologist-led care (n = 131). Both types of care have involved the history of patients, care regarding effects and adverse effects of pharmacological treatments, patients education, overall well-being, everyday life, counseling, clarifications, and rehabilitation. Additionally, there were a cohort in which patients did not receive any nontreatment care (NN cohort, n = 141). All patients have definite depression and anxiety (hospital anxiety and depression scale Chinese version score ≥ 11) before nontreatment interventions. At 2.5 years of treatments with or without nontreatment interventions (EL) DAS28-CRP, depression, and anxiety scores of patients of the NC cohort were decreased as compared to their before any type of nontreatment interventions conditions and those of patients of the RC and NN cohorts at EL (P < .001 for all). At EL numbers of patients with moderate disease activity, (DAS28-CRP score: 3.2-5.1) and borderline depression and anxiety (hospital anxiety and depression scales Chinese version score: 8-10) were greater in the NC cohort than those of the RC and NN cohorts (P < .001 for all). Outpatient care satisfaction scores of patients of the NC cohort were higher than those of the RC [23 (27-17) vs 17 (21-14)] and NN [23 (7-17) vs 15 [18-12]) cohorts (P < .001 for both). Physiological and psychological conditions of patients with rheumatoid arthritis with DAS28-CRP > 5.1 are required to improve. Nurse-supported care is superior nontreatment compared to rheumatologist-led care in rheumatoid arthritis patients with high disease activity (Level of Evidence: IV; Technical Efficacy: Stage 5).

Male rheumatoid arthritis patients at substantially higher risk for cardiovascular mortality in comparison to women

BackgroundPatients with rheumatoid arthritis (RA) are at an increased risk for developing cardiovascular diseases. While advice regarding cardiovascular risk screening and management in RA patients has been incorporated in several guidelines in recent years, its implementation and adherence is still poor. ObjectivesTo assess the cardiovascular disease risk in new diagnosed RA patients and evaluate whether advice to initiate preventive medical treatment of high risk patients was followed. MethodsAll patients with a recent diagnosis of RA, aged 40–70 years, were screened between May 2019 and December 2022 for cardiovascular diseases and risk factors within the first year after diagnosis at the outpatient rheumatology clinic, as part of standard care. Screening included a physical examination with blood pressure measurement, and laboratory tests with lipid profile tests. All patients and their general practitioner (GP) received an overview with their cardiovascular risk profile and a calculated 10-year cardiovascular mortality risk. Cardiovascular risk was defined as low (<1%), intermediate (1–5%), high (5–10%) and very high (>10%). The national pharmacy network was consulted to check whether or not patients started preventive medication after screening. ResultsA total of 125 RA patients was included in this study. The mean age was 56 years and 78% was female. Median RA disease duration at screening was 6 months. Six patients (5%) indicated to have been screened before, and used antihypertensive medication. During screening, hypertension was found in 57% of male patients and 43% of female patients and dyslipidemia was found in 36% in male and 32% in female patients. 46% of male patients and 21% of female patients currently smoked. A high or very high 10-year cardiovascular mortality risk was found in 50% of male patients, but in only 4% of female patients. Only 26% of (very) high risk patients started antihypertensive or statin medication after screening. ConclusionsAn increased cardiovascular disease risk is often present in newly diagnosed RA patients, especially male patients, with a large proportion having undiagnosed and untreated hypertension and hypercholesterolemia. Even with structural screening and informing of the patients and GPs, treatment of cardiovascular risk factors in high risk patients remains insufficient. CV risk screening needs to be part of standard care for RA patients, with clear agreement on the responsibilities between primary and secondary care. Awareness of the importance of CVD risk screening needs to improve among both RA patients themselves and the GPs to ultimately reduce the cardiovascular burden of our patients. Obviously, a better collaboration between GPs and rheumatologists is urgently needed to lower the cardiovascular burden of our patients.

The Effectiveness of Psychological Interventions for Rheumatoid Arthritis (RA): A Systematic Review and Meta-Analysis.

Rheumatoid arthritis (RA) is a long-term disorder that significantly impairs somatic, emotional, and psychological functioning. The objective of this review is to identify, appraise, and synthesize the effects of psychological interventions (e.g., cognitive behavioral therapy (CBT), emotional disclosure (ED), group therapy (GT), mindfulness (M), patient education (PE), and relaxation (R)) on biopsychosocial outcomes in the treatment of rheumatoid arthritis (RA). A systematic search of all relevant existing randomized clinical trials (RCTs) was conducted using the following online bibliographic databases: JSTOR, PubMed, PsycNET, and The Cochrane Library. Reference lists were searched for additional reports. The Cochrane Risk of Bias tool (RoB 2.0) was used to assess the risk of bias in the included studies. After the selection process, 57 articles were included and 392 were excluded. Three separate meta-analyses were conducted involving psychological interventions as the main variables, showing: (1) significant positive medium effect sizes for average values (Hedges-g = 0.399, Z = 0.399, p = 0.009); (2) significant positive large effect sizes for maximum values (Hedges-g = 0.856, Z = 4.223, p < 0.001); and (3) non-significant results for minimum values (Hedges-g = -0.047, Z = -0.335, p = 0.738). These results demonstrate that, when grouped, psychological interventions are, on average, moderately effective in treating RA. Overall, this review shows consistent, supportive evidence that psychological interventions can significantly contribute to the standard medical care of RA patients. However, more high-quality, large-sample RCTs still need to confirm these findings.

Evaluation of a non-face to face multidisciplinary health care model in a population with rheumatoid arthritis vulnerable to covid-19 in a health emergency situation

Objectives: The COVID-19 pandemic has impacted everyday practice pattern of health care in rheumatoid arthritis (RA) patients. The objective was to evaluate the implementation of a tele-consultation program in an adult population with RA Methods: Analytical observational study longitudinal cohort (Clinical trials NCT04768413) that evaluated the effectiveness of a tele consultation model compared with a face-to-face consultation model in adult RA patients. Patients were followed 12 weeks (Jul-Oct 2020) at an RA center of excellence in Colombia. Simple random sampling was done. Two groups were included: Group A, patients who were cared for by tele-consultation care and Group B, thosewho wished to continue with the usual face-to-face consultation. Data regarding activity of disease (Week 0,6,12) [Patient Activity Scale (PAS) in both groups and DAS28 in group B], and Quality of life [EQ-5D-3L], disability [Health Assessment Questionnaire (HAQ)], therapeutic adherence [Morisky-Green Adherence Scale (MGLS)] and self-care capacity [Appraisal of Self-care Agency Scale -Revised (ASA-R)] were evaluated (weeks 0-12). Outcomes regarding COVID-19 were evaluated. Bivariate analysis was done (StataV-13;P-value remote>presential (p = 0,0001);the same result was documented in the group presential>remote>presential, with an increase in adherence (p = 0,033). 7 patients developed COVID-19 (one patient hospitalized/group A and one patient died/mixed model) Conclusion: In the tele consultation model patients remained adherent to their RA treatment, without major differences compared to the face-to-face model. It is important to know these results due to the impact they have, given the changes that will follow in the care of RA patients due the current pandemic. Studies with a longer follow-up period are required to corroborate these results.

Effect of Dietary Education on Cardiovascular Risk Factors in Rheumatoid Arthritis Patients.

The aim of this study was to investigate the effect of dietary education on cardiovascular risk factors in patients with rheumatoid arthritis. In this randomized clinical trial, 112 patients with rheumatoid arthritis were randomly assigned into two groups, intervention and control. Dietary education was provided for the intervention group in 4 sessions; anthropometric measurements, serum levels of RF, triglycerides, cholesterol, HDL, LDL, and fasting blood sugar were measured before and three months after the intervention. Data were analyzed using SPSS software and appropriate statistical tests. The mean of total cholesterol (p <0.001), triglycerides (p = 0.004), LDL (p <0.001), systolic blood pressure (p = 0.001), diastolic blood pressure (p = 0.003), FBS and BMI (p <0.001) were decreased significantly in the intervention group after education compared the control group. Traditional care for rheumatoid arthritis patients is not enough. Patients need more education in order to improve their situation.

Clinical Utility and Cost Savings in Predicting Inadequate Response to Anti-TNF Therapies in Rheumatoid Arthritis.

IntroductionThe PrismRA® test identifies rheumatoid arthritis (RA) patients who are unlikely to respond to anti-tumor necrosis factor (anti-TNF) therapies. This study evaluated the clinical and financial outcomes of incorporating PrismRA into routine clinical care of RA patients.MethodsA decision-analytic model was created to evaluate clinical and economic outcomes in the 12-month period following first biologic treatment. Two treatment strategies were compared: (1) observed clinical decision-making based on a 175-patient cohort receiving an anti-TNF therapy as their first biologic after failure of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and (2) modeled clinical decision-making of the same population using PrismRA results to inform first-line biologic treatment choice. Modeled costs include biologic drug pharmacy, non-biologic pharmacy, and total medical costs. The odds of inadequate response to anti-TNF therapies and various components of patient care were calculated based on PrismRA results.ResultsIdentifying predicted inadequate responders to anti-TNF therapies resulted in a modeled 38% increase in ACR50 response to first-line biologic therapies. The fraction of patients who achieved an ACR50 response to any therapy (TNFi and others) within the 12-month period was 33% higher in the PrismRA-stratified population than in the unstratified population (59 vs. 44%, respectively). When therapy prescriptions were modeled according to PrismRA results, cost savings were modeled for all financial variables: overall costs (4% decreased total, 19% decreased on ineffective treatments), total biologic drug pharmacy (4% total, 23% ineffective), non-biologic pharmacy (2% total, 19% ineffective), and medical costs (6% total, 19% ineffective). Female sex was the clinical metric that showed the greatest association with inadequate response to anti-TNF therapies (odds ratio 2.42, 95% confidence interval 1.20, 4.88).ConclusionsIf PrismRA is implemented into routine clinical care as modeled, predicting which RA patients will have an inadequate response to anti-TNF therapies could save > $7 million in overall ineffective healthcare costs per 1000 patients tested and increase targeted DMARD response rates in RA.Electronic Supplementary MaterialThe online version of this article (10.1007/s40744-020-00226-3) contains supplementary material, which is available to authorized users.

Interleukin 6, interleukin 17, disease-related and contextual factor association with depression, and its severity in patients with rheumatoid arthritis.

Depression is very prevalent in rheumatoid arthritis (RA) compared with the general population and may be associated with poor clinical outcomes. Identifying factors associated with depression could improve outcomes for this at risk group. However, few studies have comprehensively examined the association of contextual and disease-related factors as well as pro inflammatory cytokines interleukin 6 (IL-6) and interleukin 17 (IL-17) with depression in RA. Therefore, we aimed to identify the factors significantly associated with depression and severe depression in RA, thus providing a reference for applying clinical care interventions for patients with RA. An observational cross-sectional study was conducted on 120 RA patients. Potential determinants included contextual and disease-related factors and laboratory variables. Enzyme-linked immunosorbent assay was used to measure serum IL-6 and IL-17 levels. Depression was assessed using the Arabic version of the Beck Depression Inventory-II questionnaire. A total of 120 patients were included, and up to 67.5% had some degree of depression with 60% having moderate to severe depression. The severity of disease activity of RA (DAS28-ESR (OR, 1.63; 95% CI, 0.899-3.755), HAQ scores (OR, 1.27; 95% CI, 0.702-2.933), and VAS scores for pain (OR, 2.2; 95% CI, 1.251-5.223)), besides elevated serum IL-6 (OR, 1.51; 95% CI, 0.832-3.475), IL-17 (OR, 1.28; 95% CI, 0.706-2.947), and CRP levels (OR, 1.20; 95% CI, 0.923-2.882) were significantly associated with depression and its severity in the multivariate analysis. Depression is frequent in RA and is strongly associated to elevated serum IL-6, IL-17, CRP levels, and disease activity-related factors. Key Points • RA patients are at increased risk of developing depression, particularly if their level of disease activity scores, serum IL-6, and IL-17 levels increases. • Patient characteristics associated with depression in RA include living without family, without employments, and with co-morbid hypertension, while RA disease factors are pain, functional disability, and high disease activity. • A multidisciplinary cooperative approach to RA patient care with regular assessments of these factors associated with depression should be incorporated into routine care programs to improve patients' self care capabilities and mitigate or prevent depression in these patients.

Alternative care providers in rheumatoid arthritis patient care: a queueing and simulation analysis

ABSTRACT Patients diagnosed with rheumatoid arthritis require lifelong monitoring by a rheumatologist. Initiation of the disease-modifying anti-rheumatic drug therapy within twelve weeks of the onset of symptoms is crucial to prevent joint damage and functional disability. We examine the impact of the engagement of alternate care providers (ACP) in alleviating delay due to limited rheumatologist capacity. Using queueing theory and discrete-event simulation, we model rheumatologist-only and rheumatologist-with-ACP system configurations as closed, multi-class queueing networks with class switching.Using summary data from an actual rheumatology clinic for illustration, we analyze various parameter conditions to aid clinic managers and policymakers in decisions concerning capacity allocations and feasible patient panel size that impact timeliness of care and resource utilization.Results not only confirm that a substantial increase in RA patient panel size with an ACP involved in the care of follow-up patients but also demonstrates the boundaries for feasible panel sizes and workload allocation

The value, impact and role of nurses in rheumatology outpatient care: Critical review of the literature.

As rheumatology nurses make substantial contributions to intensive management programmes following 'treat to target' principles of people with rheumatoid arthritis (RA), there is a need to understand the impacts of their involvement. A structured literature review was undertaken of qualitative studies, clinical trials and observational studies to assess the impacts of rheumatology nurses on clinical outcomes and the experiences of patients with RA and to examine the skills and training of the nurses involved. A structured literature review was conducted to examine the value, impact and professional role of nurses in RA management. The literature search identified 657 publications, and 20 of them were included comprising: seven qualitative studies (242 patients), nine trials (a total of 2,440 patients) and four observational studies (1,234 patients). In clinical trials, nurses achieved similar patient clinical outcomes to doctors, and nurses also enhanced patients' satisfaction of received care and self-efficacy. In the qualitative studies reviewed, the nurses increased patients' knowledge and promoted their self-management. The observational studies studied examined found that nursing care led to improved patients' global functioning. The nurses in the various studies had a wide range of titles, experiences and training. Our structured literature review provides strong evidence that rheumatology nurses are effective in delivering care for RA patients. However, their titles, experience and training were highly variable. There is a convincing case to maintain and extend the role of nurses in managing RA, but further work is needed on standardisation of their titles and training.

Disease activity, morning stiffness and missing teeth are associated with oral health-related quality of life in individuals with rheumatoid arthritis

ObjectivesThe aim of this cross-sectional study was to assess oral health-related quality of life (OHRQoL) in patients with rheumatoid arthritis (RA) and its relation to specific RA characteristics.Material and methodsWithin the oral examination, the need for dental (carious teeth showing cavitation) and periodontal treatment (presence of a probing depth ≥ 3.5 mm) and the number of missing teeth (M-T) were recorded. OHRQoL was assessed with the German short version of the Oral Health Impact Profile (OHIP G14). The disease activity score (DAS28-ESR), disease duration, number of swollen/painful joints and duration of morning stiffness were retrieved from the patient records.ResultsA total of 176 patients with a mean age of 62.5 ± 10.2 years were included. The overall OHIP G14 sum score was 5.4 ± 7.1. The M-T showed a significant correlation with the dimensions of oral function (r = 0.25, p = 0.001) and psychosocial impact (r = 0.20, p = 0.009) and the sum score (r = 0.26, p = 0.001). The DAS28-ESR showed a significant correlation with psychosocial impact (r = 0.19, p = 0.012) and the sum score (r = 0.16, p = 0.041). The duration of morning stiffness was correlated with oral function (r = 0.19, p = 0.019), psychosocial impact (r = 0.18, p = 0.024) and the sum score (r = 0.22, p = 0.006). The effect size of these correlations was interpreted as small.ConclusionDisease activity, morning stiffness and missing teeth are associated to OHRQoL of patients with RA. Accordingly, multidisciplinary dental care appears necessary for these patients.Clinical relevanceThe prevention of tooth loss as well as the consideration of psychosocial and disease-specific parameters in the multidisciplinary dental care of RA patients is necessary.

Infections in Patients with Rheumatoid Arthritis in the Era of Targeted Synthetic Therapies.

The third decade of the 21st century marks the beginning of a new era in the treatment of rheumatoid arthritis (RA). Recently, after the introduction in clinical practice of different biologics in the first decade, three different oral synthetic targeted agents (JAK inhibitors) have been licensed for the treatment of RA, in patients who had failed or are intolerant to disease modifying anti-rheumatic drugs (DMARDs). Despite the significant progress that these agents bring to the care of RA patients, the risk of infections is still present and clear, given that their risk for serious infections is at least comparable with that of biologic DMARDs, whereas the incidence of herpes zoster is higher than that of bDMARDs. Here, we review the most recent data regarding the risk for serious and opportunistic infections in RA patients treated with biologics or JAK inhibitors, as well the up-to-date approach for managing and preventing such infections in RA patients.

Association between overweight/obesity and clinical activity in rheumatoid arthritis

IntroductionThe effect of overweight/obesity on clinical status in rheumatoid arthritis (RA) is still a controversial topic. AimTo assess the association between body composition and clinical status in RA patients. MethodsA prospective, comparative, cross-sectional study was performed on 123 (98.4% women, 86.3% FR+, 9.3±8.7 duration years) RA patients diagnosed according to ACR/EULAR 2010 criteria who were assessed for inflammatory activity (DAS 28), functional status (HAQ-Di), and type of treatment. Body composition was evaluated by BMI, waist, hip, and middle arm girths, waist/hip ratio, skin fold measurements, and bioelectrical impedance analysis. ResultsThe prevalence of overweight and obesity (BMI-WHO cut-off points) was 30.9% and 45.5% respectively. Using Stavropoulos-Kalinoglou cut-off points, each corresponding prevalence increased to 31.7% and 58.5%, respectively. Pooled patients in the overweight/obesity classification (Stavropoulos-Kalinoglou classification) exhibited a significantly higher number of swollen joints as compared to subnormal/normal body composition subjects (3.8±3.3 vs 1.9±2.5; P=.02). Swollen joint count showed significant positive correlation with 6 out of 11 body composition parameters: BMI; arm and hip girths, triceps skin fold, body fat average determined by bioelectrical impedance analysis, and skin fold measurements. ConclusionsPrevalence of obesity in RA varies according to BMI cut-off points. Overweight and obesity were associated with higher inflammatory activity characterised by a higher count of tender and swollen joints. A positive correlation was found between swollen joint amount and the majority of the body fat mass indicators assessed. Body composition assessment/improvement should be an important part of the routine care of RA patients.

Effectiveness and safety of physician–pharmacist collaborative care for rheumatoid arthritis patients: The Changi General Hospital’s experience

Background: Increasing demand for follow-up of rheumatoid arthritis has encouraged pharmacists to collaborate with physicians to assist with patient care. Objective: The aim of this study was to assess the effectiveness and safety of the collaborative care model in a rheumatoid arthritis clinic. Methods: We performed a retrospective review of patient case notes and medication records from March 2013 to February 2016. The effectiveness and safety of collaborative care was examined in pre-implementation (standard care) versus post-implementation (collaborative care) cohorts. All patients were assessed for 12 months. Effectiveness of clinic was measured using the percentage of patients that achieved optimal doses of non-biologic disease-modifying anti-rheumatic drugs (nb-DMARDs). Clinic safety performance was evaluated based on the percentage of patients in each cohort that achieved compliance to in-house hospital guidelines on nb-DMARD monitoring. Other clinic safety factors monitored included the incidence and characteristics of nb-DMARD-associated adverse drug events. Results: Thirty-eight patients who had received standard care and collaborative care were reviewed. More patients receiving collaborative care achieved nb-DMARD dose optimization within a year of initiation of therapy (68.4% vs 39.5%; p-value &lt; 0.05). Compliance to safety recommendations from hospital guidelines on nb-DMARD monitoring was significantly higher in the collaborative care group (70.6% vs 44.1%; p-value &lt; 0.05). Collaborative care resulted in a higher incidence of nb-DMARD-associated adverse drug events being detected (26.3% vs 18.4%; p-value &lt; 0.05). The most common adverse drug events were gastrointestinal (29.4%), dermatological (17.6%), and hematologic (17.6%), the majority being mild in severity. Conclusion: Collaborative rheumatoid arthritis care contributed to improvements in nb-DMARD dose optimization, compliance to hospital guidelines on monitoring, and the detection of nb-DMARD-related adverse drug events.

Assessment of pain in rheumatoid arthritis. Practical significance

The chief complaint of patients with rheumatoid arthritis (RA) is pain. The latter is one of the main signs of chronic inflammation, which holds a central position in the clinical picture of the disease. Pain is not among the baseline parameters that are used to calculate total disease activity indices. Nevertheless, pain greatly influences the result of RA activity determination using the total indices. However, this assessment system can take into account only the intensity of pain, whereas the clinical significance of pain syndrome is largely determined by its nature. The causes of pain in RA can be different in different patients and even in one patient at early and late stages of the disease, during the periods of exacerbation and attenuation of the inflammatory activity. Pain in RA is not always associated with the active inflammatory process. At the same time, intense non-inflammatory pain can significantly affect the traditional indicators of inflammatory activity, by distorting the result of quantitative determination of disease activity. In turn, an erroneous activity assessment may cause an incorrect choice of treatment policy. Therefore, the clinical use of tools that reliably determine the nature of pain, can contribute to a significant improvement in the quality of care for RA patients. In most cases pain in RA is associated with inflammatory changes in joints or periarticular soft tissues. Therefore along with disease-modifying anti-rheumatic drugs, nonstreroidal anti-inflammatory drugs (NSAIDs) are widely used in the combination therapy of RA. However, their use is limited by a risk of adverse reactions. Etoricoxib is one of the highly effective drugs with a good safety profile. Currently, there are no recommendations for the treatment of neuropathic pain in patients with RA. Investigating the efficacy of tricyclic antidepressants and cannabinoids in RA has failed to prove their advantages over placebo.

The effect of periodontal treatment on patients with rheumatoid arthritis: The ESPERA randomised controlled trial.

To assess the effect of periodontal treatment on clinical and biochemical parameters of rheumatoid arthritis (RA) and quality of life (QoL) in patients with moderately active RA who were diagnosed with periodontitis. In this open-label randomised controlled trial, RA subjects (n = 22) were allocated to "immediate" or "delayed" periodontal treatment (full-mouth non-surgical scaling and root planing, systemic antibiotics, and oral hygiene instructions). The main outcome was the 3-month change on the Disease Activity Score 28 based on the Erythrocyte Sedimentation Rate (DAS28-ESR). The Health Assessment Questionnaire and the General Oral Health Assessment Index were used to assess general and oral health QoL, respectively. Periodontal health significantly improved after periodontal treatment (P = 0.03). Periodontal treatment appeared to be safe but led to no significant effects on the DAS28-ESR (adjusted mean difference with 95% confidence interval (aMD) of -0.03 [-0.98; 0.92]). There was no evidence of improvement in the general QoL after periodontal treatment and no significant effect was found for the oral health QoL, despite a positive trend in the "psychological impacts" domain (aMD of 0.13 [-0.07; 0.33], P = 0.20). Although no clinical effect of periodontal treatment on RA was identified, this trial provides important data to support periodontal care in RA patients. Periodontal treatment is safe and reduces oral inflammation with a possible effect on oral health QoL. Since both periodontitis and RA are complex and multifactorial chronic diseases, it is likely that patient-centred approaches involving both oral health professionals and rheumatologists will contribute to optimal patient care.

The Mediterranean diet, fish oil supplements and Rheumatoid arthritis outcomes: evidence from clinical trials.

The impact of dietary interventions such as specific types of diet or nutritional supplements in rheumatoid arthritis (RA) has been subject to increased attention in recent years. The recognition of the unmet need to better understand the effects of specific dietary interventions on disease outcomes in RA, along with the growing patient interest on lifestyle interventions beyond pharmacotherapy, have informed the undertaking of this narrative literature review. The benefits of the Mediterranean Diet (MD) have been shown in various studies, although only a limited number of trials focus specifically on RA. Based on the studies reviewed, the MD may provide benefits in reducing pain and swollen and tender joints in RA patients. There is more and better evidence that n-3 polyunsaturated fat (PUFA) supplementation has the potential to reduce inflammation and provide clinical benefit, possibly slowing progression to pharmacotherapy. Yet, many of these studies to date are limited in their methodology; this being partly a reflection of the complexity of the research questions being addressed. Consequently, the conclusions that can be robustly drawn from their results are restricted. With a focus on clinical trials on the MD and fish oil supplementation, this review critically appraises the evidence, discussing the findings of studies in the wider context of impact on RA outcomes, methodological challenges, and practical points to consider as part of the routine care of RA patients.
