Is current smoking status and its relationship to anti-cyclic citrullinated peptide antibodies a predictor of worse response to biological therapies in rheumatoid arthritis patients?

OBJECTIVE: To assess the association between smoking, anti-cyclic citrullinated peptide (anti-CCP) antibody status, and clinical efficacy of biological therapies in rheumatoid arthritis (RA) patients. METHOD: This retrospective clinical practice setting study included 1349 RA patients from the METEOR database (aged >18 years). We collected data on sociodemographics, smoking status (smoker, <10, 10-19, and >20 cigarettes/day; ex-smoker; non-smoker), baseline disease activity parameters and anti-CCP, previous disease-modifying anti-rheumatic drugs (DMARDs), biological therapy, combined therapy (steroids and DMARDs), and follow-up disease activity. Clinical efficacy was assessed by European League Against Rheumatism (EULAR) good/moderate response rates for all aggregated biological therapies, based on both smoking and anti-CCP status. RESULTS: The non-smoking RA patients were more often female at biological therapy initiation than the ex-smokers and smokers (91.1% vs 60.4% and 67.9%, respectively, p < 0.001), and ex-smokers were older than non-smokers and smokers (mean ± sd 56.5 ± 11.1, 53.5 ± 13.3 and 51.3 ± 11.0 years old, respectively; p < 0.001). In total, 845 (62.6%) were non-smokers, 214 (15.9%) ex-smokers, and 290 (21.5%) smokers [daily cigarettes smoked: 148 (11%) <11; 61 (4.5%) 11-20; and 81 (6%) >20]. Anti CCP-antibody status was similar in both groups. Non-smokers showed higher baseline DAS28 than ex-smokers and smokers (5.0 ± 1.5 vs 4.7 ± 1.4 and 4.7 ± 1.4, respectively; p < 0.001) and used more baseline steroids and DMARDs. A higher EULAR response rate was observed in non-smokers than in ex-smokers and smokers (73% vs 65% and 64.1%, respectively; p = 0.004). Drug survival was higher in non-smokers compared to ex-smokers and smokers [57.7 months (46.4-53.8), 38.6 (30.3-46.8), and 50.1 (41.8-58.4); p < 0.001, respectively]. CONCLUSION: In daily clinical practice, non-smokers respond better than smokers to biological therapy, but this does not result in better drug survival.

EULAR/EFORT recommendations for management of patients older than 50†years with a fragility fracture and prevention of subsequent fractures.

The European League Against Rheumatism (EULAR) and the European Federation of National Associations of Orthopaedics and Traumatology (EFORT) have recognised the importance of optimal acute care for the patients aged 50 years and over with a recent fragility fracture and the prevention of subsequent fractures in high-risk patients, which can be facilitated by close collaboration between orthopaedic surgeons and rheumatologists or other metabolic bone experts. Therefore, the aim was to establish for the first time collaborative recommendations for these patients. According to the EULAR standard operating procedures for the elaboration and implementation of evidence-based recommendations, 7 rheumatologists, a geriatrician and 10 orthopaedic surgeons met twice under the leadership of 2 convenors, a senior advisor, a clinical epidemiologist and 3 research fellows. After defining the content and procedures of the task force, 10 research questions were formulated, a comprehensive and systematic literature search was performed and the results were presented to the entire committee. 10 recommendations were formulated based on evidence from the literature and after discussion and consensus building in the group. The recommendations included appropriate medical and surgical perioperative care, which requires, especially in the elderly, a multidisciplinary approach including orthogeriatric care. A coordinator should setup a process for the systematic investigations for future fracture risk in all elderly patients with a recent fracture. High-risk patients should have appropriate non-pharmacological and pharmacological treatment to decrease the risk of subsequent fracture.

Cost-effectiveness and cost-utility of add-on, low-dose prednisolone in patients with rheumatoid arthritis aged 65+: The pragmatic, multicenter, placebo-controlled GLORIA trial.

BACKGROUND: The GLORIA placebo-controlled trial found a favorable balance of benefit and harm for two years of prednisolone (5 mg/day) as add-on treatment for rheumatoid arthritis (RA) patients aged 65+. This study evaluated the cost-effectiveness of low-dose prednisolone in the treatment of RA. METHODS: The economic evaluation had a societal perspective with a time horizon of two years. Cost data were collected with questionnaires and from recorded events, and valued with standard Dutch unit prices of 2017. The primary effectiveness outcome was the disease activity score in 28 joints (DAS28). For cost-utility, quality-adjusted life years (QALYs) were estimated from the EuroQol-5 Dimension (EQ-5D) questionnaire. Bootstrapping assessed the uncertainty around the average differences in costs and health outcomes. RESULTS: In total, 444 of 451 randomized patients were included in the modified intention-to-treat analysis. Patients had median four active comorbidities at baseline. Mean total costs over two years were k€10.8 in the prednisolone group, k€0.5 (95% CI -4.0; 1.8) lower than in the placebo group. Total direct medical costs were k€0.5 (95% CI -4.0; 1.5) lower in the prednisolone group. The mean number of QALYs was similar in both groups (difference 0.02 [-0.03; 0.06] in favor of prednisolone). The DAS28 was 0.38 lower in the prednisolone group than in the placebo group (0.19; 0.56). CONCLUSION: With greater effectiveness (DAS28) at non-significantly lower costs, low-dose, add-on prednisolone is cost-effective for RA compared to placebo over two years. QALYs were equal in both groups, most likely due to the impact of multiple comorbidities.

Ultrasound and elastography in the assessment of skin involvement in systemic sclerosis: A systematic literature review focusing on validation and standardization - WSF Skin Ultrasound Group.

OBJECTIVE: To summarize the published evidence in the literature on the role of ultrasound and elastography to assess skin involvement in systemic sclerosis (SSc). METHODS: A systematic literature review (SLR) was performed within the "Skin Ultrasound Working Group" of the World Scleroderma Foundation, according to the Cochrane Handbook. A search was conducted in Pubmed, Cochrane Library and Embase databases from 1/1/1979 to 31/5/2021, using the participants, intervention, comparator and outcomes (PICO) framework. Only full-text articles involving adults, reported in any language, assessing ultrasound to quantify skin pathology in SSc patients. Two reviewers performed the assessment of risk of bias, data extraction and synthesis, independently. RESULTS: Forty-six studies out of 3248 references evaluating skin ultrasound and elastography domains were included. B-mode ultrasound was used in 30 studies (65.2%), elastography in nine (19.6%), and both methods in seven (15.2%). The ultrasound outcome measure domains reported were thickness (57.8%) and echogenicity (17.2%); the elastography domain was stiffness (25%). Methods used for image acquisition and analysis were remarkably heterogeneous and frequently under-reported, precluding data synthesis across studies. The same applies to contextual factors and feasibility. Our data syntheses indicated evidence of good reliability and convergent validity for ultrasound thickness evaluation against mRSS and skin histological findings. Stiffness and echogenicity have limited evidence for validity against histological findings. Evidence for sensitivity to change, test-retest reliability, clinical trial discrimination or thresholds of meaning is limited or absent for reported ultrasound domains. CONCLUSION: Ultrasound is a valid and reliable tool for skin thickness measurement in SSc but there are significant knowledge gaps regarding skin echogenicity assessment by ultrasound and skin stiffness evaluation by elastography in terms of feasibility, validity and discrimination. Standardization of image acquisition and analysis is needed to foster progress.

Primary Breast Lymphoma with cutaneous involvement in a patient with Rheumatoid Arthritis - a complication of infliximab therapy?

It is well established that rheumatoid arthritis is associated with an increased risk of lymphoma. The use of tumor-necrosis factor-α inhibitors as a therapy in rheumatoid arthritis has been related to higher incidence of lymphoma arising at atypical and/or unusual locations; however, recent data shows their safety. We report the case of a 79 year-old woman with rheumatoid arthritis treated with infliximab, who presented a primary breast lymphoma with cutaneous involvement.
