- Background: Chronic pain, regional or widespread, is a frequent and multidimensional symptom in arthritis. There is still limited information on chronic pain in spondyloarthritis, which is important to recognize for adequate diagnosis and treatment. Our objective was to study differences in prevalence of chronic widespread pain in two spondyloarthritis subgroups: ankylosing spondylitis (AS) and undifferentiated spondyloarthritis (USpA).Methods: A population-based postal survey involving questions on the duration, distribution, and intensity of pain was answered by 940 patients with AS (ICD-10 M45.9) or USpA (ICD-10 M46.1-0, M46.8-9). The patients were categorized as having chronic widespread pain, chronic regional pain, or no chronic pain, and prevalence estimates for the pain groups were calculated, including age- and sex-adjusted prevalence.Results: The prevalence of chronic widespread pain was 45.3% in AS vs. 49.3% in USpA, and that of chronic regional pain was 17.7% vs. 21.9% (p = 0.033). More women than men reported having chronic widespread pain (54.1% vs. 41.2%, p ≤ 0.001), while the sex distribution for chronic regional pain was equal. Reports of pain intensity were equal in AS and USpA, with no significant difference in pain intensity between women and men who had chronic regional pain or chronic widespread pain. In the multiple logistic regression analysis, chronic widespread pain was associated to female sex, being an ever-smoker, and having a higher body mass index, controlled for SpA subgroup and disease duration. Conclusions: The prevalence of chronic widespread pain in patients with AS and USpA is high, and with a female predominance, but with no difference in pain intensity between women and men. Chronic pain can complicate the clinical evaluation in patients with SpA, and highlights the need for a thorough clinical examination, including evaluation of inflammation and an accurate pain analysis, to individualize non-pharmacological and pharmacological treatment decisions © 2018 The Author(s).

- Background: Pneumococcal vaccination is recommended to patients with rheumatoid arthritis (RA) and primary Sjögren’s syndrome (pSS). However, little is known whether the diseases influence pneumococcal vaccine response. This study aimed to investigate antibody response and functionality of antibodies following immunization with 13-valent pneumococcal conjugate vaccine (PCV13) in RA patients or pSS patients without disease modifying anti-rheumatic drugs (DMARD), compared to patients with RA treated with DMARD or to healthy controls. Methods: Sixty RA patients (50 without DMARD and 10 with MTX), 15 patients with pSS and 49 controls received one dose of PCV13. Serotype-specific antibody concentrations for pneumococcal polysaccharides 6B and 23F and functionality of antibodies (23F) were determined in serum taken before and 4–6 weeks after vaccination using ELISA and opsonophagocytic activity assay (OPA), respectively. Proportions of individuals with positive antibody response (i.e. ≥ 2-fold increase from prevaccination concentrations; antibody response ratio; ARR ≥ 2), percentage of individuals reaching putative protective antibody level (i.e. ≥1.3 μg/mL) for both serotypes, and difference in OPA were calculated. Results: After vaccination, antibody concentrations for both serotypes increased in RA without DMARD (p < 0.001), pSS (p ≤ 0.05 and < 0.01) and controls (p < 0.001). Antibody responses to 6B and 23F were comparable in RA without DMARD (64% and 74%), pSS (67% and 53%) and controls (65% and 67%), but lower in the small group RA with MTX (both 20%, p < 0.01). Similarly, significant increases of patients reaching protective antibody levels were seen in RA without DMARD (p ≤ 0.001) and controls (p < 0.001). After vaccination, OPA increased significantly in controls, RA and pSS without DMARD (p < 0.001 to 0.03), but not in RA with MTX. Conclusions: Pneumococcal conjugate vaccine is immunogenic in RA and pSS patients without DMARD and in line with previous studies we support the recommendation that vaccination of RA patients should be performed before the initiation of MTX.

- BackgroundThere is increasing interest in the identification of people at risk of rheumatoid arthritis (RA) to monitor the emergence of early symptoms (and thus allow early therapy), offer lifestyle advice to reduce the impact of environmental risk factors and potentially offer preventive pharmacological treatment for those at high risk. Close biological relatives of people with RA are at an increased risk of developing RA and are therefore potential candidates for research studies, screening initiatives and preventive interventions. To ensure the success of approaches of this kind, a greater understanding of the perceptions of this group relating to preventive measures is needed.MethodsTwenty-four first-degree relatives of patients with an existing diagnosis of RA from the UK, three from Germany and seven from Austria (age: 21-67 years) took part in semi-structured interviews exploring their perceptions of RA risk, preventive medicine and lifestyle changes to reduce RA risk. Interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis.ResultsMany first-degree relatives indicated that they anticipated being happy to make lifestyle changes such as losing weight or changing their diet to modify their risk of developing RA. Participants further indicated that in order to make any lifestyle changes it would be useful to know their personal risk of developing RA. Others implied they would not contemplate making lifestyle changes, including stopping smoking, unless this would significantly reduce or eliminate their risk of developing RA. Many first-degree relatives had more negative perceptions about taking preventive medication to reduce their risk of RA, and listed concerns about potential side effects as one of the reasons for not wanting to take preventive medicines. Others would be more willing to consider drug interventions although some indicated that they would wish to wait until symptoms developed.ConclusionsInformation targeted at those considered to be at risk of RA should contain information about RA, the extent to which risk can be quantified at an individual level and how risk levels may differ depending on whether early symptoms are present. The benefits (and risks) of lifestyle changes and pharmacological interventions as potential preventive measures should be clearly described.
