Current Rheumatology Reviews - Volume 11, Issue 1, 2015

Objectives: Patient experience is not routinely measured in rheumatoid arthritis (RA) and no accepted standardised Patient Reported Experience Measures (PREM) tools currently exist. Commissioning for Quality in Rheumatoid Arthritis (CQRA) has developed, piloted and validated PREMs for RA and other rheumatic conditions. Methods: Focus groups were held with RA patients to identify key elements of the patient experience. These were mapped against the UK Department of Health Patient Experience Framework and a PREM questionnaire developed with questions specifically relating to RA and rheumatology services. The RA PREM was piloted and Cronbach’s alpha used to assess internal consistency. The PREM was modified to capture experience of patients with other rheumatic conditions and further validated. Results: Ten UK sites and 524 patients were included in the RA PREM pilot and validation analysis. The RA PREM reliably captured RA patient experience and had good construct validity. Cronbach’s alpha within the multiquestion domains ranged from 0.61 to 0.90 and the percentage agreement ranged from 22.5% to 70.4% with overall care. The modified PREM was evaluated in 11 UK sites and 110 patients with a range of rheumatic conditions. Cronbach’s alpha ranged from 0.76 to 0.91 and the percentage agreement similarly ranged from 70% to 90% with the question on overall care. Conclusions: The RA PREM and the modified PREM provide new valuable validated tools for capturing the patient experience in a range of rheumatic conditions. The RA PREM is currently being used in a UK National Clinical Audit of Rheumatoid and Early Inflammatory Arthritis.

Background: Current studies and research support the role of metabolic syndrome (MetS) in knee osteoarthritis (OA). However, few studies have focused on its impact on knee OA parameters. The aim of this study was to investigate if metabolic syndrome or its individual components affect the intensity of pain, functional disability, and radiographic severity in knee osteoarthritis women. Materials and Methods: We conducted a cross sectional study including confirmed radiographic knee osteoarthritis according to Kellgren and Lawrence scale, with and without metabolic syndrome according to the National Cholesterol Education Program Adult Treatment Panel III criteria. The two groups were compared for pain Visual Analogue Scale (VAS), Lequesne index, Womac function, and radiological grade after adjusting for significant covariates. Multiple regression analysis was used to identify the independent effects of each specific component for metabolic syndrome on knee osteoarthritis parameters. Results: One hundred thirty women were included. The mean age was 56.68 ±8.07 [34-75] years, and the mean BMI was 32.54±2.92 [23-37] kg/m2. The prevalence of metabolic syndrome was 48.5%. Women with and without metabolic syndrome had similar knee osteoarthritis parameters. However, accumulation of MetS components was associated with higher level of pain (OR = 3.7, CI = [1.5-5.9], p=0.001), independently of age and BMI. Multiple regression analyses showed, after adjusting for all covariates, that hyperglycemia had a positive impact on pain (p=0.009), waist circumference was positively associated with Lequesne index (p=0.04), high triglycerides level was significantly associated with increased pain (p=0.04) and higher Lequesne score (p=0.05), and Systolic blood pressure was positively correlated with Lequesne index (p=0.01). Conclusion: In addition to weight reduction, appropriate treatment of metabolic syndrome needs to become an important management strategy for knee pain and functional impairment.

Fibromyalgia (FM) is a characterized by generalized pain with widespread tender points in specific areas and is frequently accompanied by fatigue, stiffness, and a non-restorative sleep pattern. In the current retrospective study, we identified a subgroup of FM patients who had clinically important markers of inflammation. The study also explored the use of the original American College of Rheumatology (ACR) criteria in the diagnosis of FM. Our data suggested there was a distinct subset of patients with FM who had positive ESR, CRP, ANA and RF; a group that we considered representative of inflammatory FM. None of the FM patients in this study developed a documented coexisting autoimmune illness during the retrospective review period. The existence of FM subgroups further puts into question the already controversial use of either the new or old ACR classification criteria in the diagnosis of FM, as they do not address the issue of systemic inflammation which appears to be significant.

Objective: To assess the relationship between disease activity, measured by DAS28, and radiographic progression, using X-Ray and US as tools to evaluate structural joint damage and residual inflammation, in early RA patients. Methods: Changes from baseline to week 52 in clinical variables and measures of radiographic progression were compared between early RA patients who received anti-TNF biologic therapy (192 patients), and those who received synthetic DMARD therapy (288 patients). Patients were stratified into: in remission, low (LDA), moderate (MDA) and high (HDA) disease activity at 52-weeks of treatment according to DAS-28 score. Radiographic progression was assessed both at baseline and at 52-weeks using modified Total Sharp Score (mTSS). In addition, US scores for number of erosions, synovial hypertrophy and vascularity were recorded. Results: Whilst there was no significant radiologic progression in the patients who achieved remission, whether treated with synthetic DMARD or biologic therapy; on the other hand, there was a steady increase of joint damage in those who did not achieve remission, mainly in those treated with synthetic DMARD and in favor of the biologic therapy. On comparing the MSS scores at 52-weeks, the biologic therapy cohort who showed LDA (DAS-28: 2.6-3.1), MDA (DAS-28 score > 3.2-5.1) and HDA (>5.1) had significantly (p< 0.001) less number of erosions and joint space narrowing (P< 0.001) as well as US-GS and US-PD scores in comparison to the synthetic DMARD therapy cohort. X-Ray and US parameters showed a discriminating value regarding joint damage particularly in the patients who did not achieve remission, with US parameter showing accurate 95% CI estimate. Conclusion: Using US as a sensitive tool for joint affection assessment, the combination of biologic and DMARDs therapies retards joint damage, independently of its effects on disease activity, contrasting synthetic DMARDs monotherapy.

Background: Rheumatoid arthritis (RA) is an autoimmune disease that tends to be progressive and chronic. Previous studies showed that oxidative stress has a main role in pathology of RA. The aim of this study was the easy elucidation of oxidative stress through pro-oxidant-antioxidant balance (PAB) in these patients. Method: The sera of 130 RA patients and 130 age-matched healthy subjects (HS) were collected and the PAB was measured. According to the normal value of PAB in HS, the patients were divided into two groups; patients with increased serum PAB and those with normal serum PAB values. In patients with increased PAB value, the correlation of PAB value with RA disease activity [(DAS28ESR)], biochemical parameters, and BMI were determined. Results: Significantly higher serum PAB values were found in the whole RA group of patients (88.69±39.42 HK) in comparison to HS (53.57±25.10 HK), p ≤ 0.05. There was no significant correlation between PAB values and RA disease activity. In patients with elevated serum PAB value; serum cholesterol, triglycerides and BMI were significantly higher in comparison to patients with normal values. Conclusion: The PAB test can show the oxidative stress in RA patients. Further research should be done to determine the potency of the PAB assay as a tool for monitoring adverse effect of oxidative stress in RA, as well as the effect of antioxidant therapies in the outcomes.

Rheumatoid arthritis is the commonest inflammatory arthropathy, and affects synovium, cartilage and bone. Despite recent improvements with disease modifying biological agents, progressive joint destruction may continue eventually leading to the need for joint arthroplasty. The knee joint is involved in 90% of patients with rheumatoid arthritis, and total knee arthroplasty is being performed in many patients to alleviate pain and recover function. However, complications are not uncommon. In this review of the literature we look at pre-operative, intra-operative and post-operative factor that need to be taken into account to reduce the risk of complications in these patients. Due to the systemic nature of rheumatoid arthritis, a multi-disciplinary approach is crucial. This includes addressing medical and pharmacological issues, and anesthetic concerns pre-operatively, and anticipating and preventing relevant complications postoperatively.

Thumb carpometacarpal joint osteoarthritis is the most common site of non-rheumatic degenerative lesion in the hand, and there are special features in rheumatic patients. None of various surgical treatment options can be declared as "gold standard" recently. The surgical treatment depends on patient's age, patient's claims in work and leisure, local bone stock, possible allergies, local comorbities, and local deformities.

The role of oral bacteria in the etiology of ankylosing spondylitis (AS) is examined in this review. Periodontitis is related to AS to a significant degree, and periodontitis is significantly more prevalent in patients with AS. Anti-Pophyromonas gingivalis and anti-Prevotella intermedia antibodies titers are higher in AS patients than in healthy subjects. Eight randomized controlled trials that used sulfasalazine were reviewed. Moxifloxacin and rifamycin are significantly effective in the treatment of AS. Periodontal pathogens are likely to be responsible for the development of AS in genetically susceptible individuals. These results will guide more comprehensive and efficacious treatment strategies for AS.

Osteoarthritis (OA) of the knee is a wide-spread, debilitating disease that is prominent in Western countries. It is associated with old age, obesity, and mechanical stress on the knee joint. By examining the recent literature on the effect of the anti-inflammatory prostaglandins 15d-PGJ2 and Δ12-PGJ2, we propose that new therapeutic agents for this disease could facilitate the transition from the COX-2-dependent pro-inflammatory synthesis of the prostaglandin PGE2 (catalyzed by mPGES-1), to the equally COX-2-dependent synthesis of the aforementioned anti-inflammatory prostaglandins. This transition could be instrumental in halting the breakdown of cartilage via matrix metalloproteinases (MMPs) and aggrecanases, as well as promoting the matrix regeneration and synthesis of cartilage by chondrocytes. Another desirable property of new OA therapeutics could involve the recruitment of mesenchymal stem cells to the damaged cartilage and bone, possibly resulting in the generation of chondrocytes, synoviocytes, and, in the case of bone, osteoblasts. Moreover, we propose that research promoting this transition from pro-inflammatory to anti-inflammatory prostaglandins could aid in the identification of new OA therapeutics.

Rheumatoid arthritis affects around 1% of the global population with a predilection for Western societies. The treatment of the rheumatoid hip has gone through significant changes in recent years. Although osteotomies and synovectomies were previously commonplace, advances in arthroplasty technique and technology has seen these former procedures being performed less commonly. This article tackles some of the key issues with regard to the rheumatoid hip, namely the increased risk and methods of dealing with protrusio acetabuli, the risk of dislocation, infection and rates of aseptic loosening.

Rheumatoid arthritis (RA) is an autoimmune connective tissue disease of unknown etiology with development of persistent and erosive arthritis ultimately resulting in disability. The prevalence of RA is about 0.5-1% in adults worldwide. Radiographic changes in the joints at early stages of the disease are often absent. Accordingly, there is a need for instrumental methods of diagnosis with greater sensitivity. These include magnetic resonance imaging and ultrasound of joints. The paper reviews the instrumental methods of diagnosis of joint damage in early RA according to the existing literature of PubMed database. Selection criteria were original articles in the English language reporting «X-ray», «MRI» and «ultrasound» in patients with early RA.
