Abstract
OBJECTIVES Tumour necrosis factor inhibitors (TNFi) are effective in psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA), but are associated with a small (0.6%) increase in serious infection risk, patient burden due to need for self-injection and high costs. Treat-to-target (T2T) tapering might ameliorate these drawbacks, but high-quality evidence on T2T tapering strategies is lacking in PsA and axSpA. METHODS We performed a pragmatic open-label, monocentre, randomised controlled non-inferiority (NI) trial on T2T tapering of TNFi. Patients with PsA and axSpA using a TNFi with ≥6 months stable low disease activity (LDA) were included. Patients were randomised 2:1 to disease activity-guided T2T with or without tapering until withdrawal and followed-up to 12 months. Primary endpoint was the difference in proportion of patients having LDA at 12 months between groups, compared with a prespecified NI margin of 20%, estimated using a Bayesian prior. RESULTS 122 patients (64 PsA and 58 axSpA) were randomised to a T2T strategy with (N=81) or without tapering (N=41). The proportion of patients in LDA at 12 months was 69% for the tapering and 73% for the no-tapering group: adjusted difference 5% (Bayesian 95% credible interval: -10% to 19%) which confirms NI considering the NI margin of 20%. The mean percentage of daily defined dose was 53% for the tapering and 91% for the no-tapering group at month 12. CONCLUSIONS A T2T TNFi strategy with tapering attempt is non-inferior to a T2T strategy without tapering with regard to the proportion of patients still in LDA at 12 months, and results in a substantial reduction of TNFi use.

PolyMyalgia Rheumatica treatment with Methotrexate in Optimal Dose in an Early disease phase (PMR MODE): study protocol for a multicenter double-blind placebo controlled trial. Trials 2022; 23:318. [PMID: 35428320 PMCID: PMC9012047 DOI: 10.1186/s13063-022-06263-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 03/31/2022] [Indexed: 11/21/2022] Open
Abstract
Background Polymyalgia rheumatica (PMR) is an inflammatory rheumatic disease affecting people older than 50, resulting in pain and stiffness of the neck, shoulder, and pelvic girdle. To date, glucocorticoids (GC) remain the cornerstone of treatment, but these have several drawbacks. Firstly, a large proportion of patients do not achieve GC-free remission within either the first (over 70%) or second year of treatment (over 50%). Secondly, GC-related adverse events (AE) occur in up to 65% of patients and can be severe. The current EULAR/ACR guidelines for PMR recommend early introduction of methotrexate (MTX) as a GC sparing agent in patients at risk for worse prognosis. However, earlier trials of low to medium quality only studied MTX dosages of 7.5–10 mg/week with no to modest effect. These doses may be suboptimal as MTX is recommended in higher doses (25 mg/week) for other inflammatory rheumatic diseases. The exact role, timing, and dose of MTX in PMR remain unclear, and therefore, our objective is to study the efficacy of MTX 25 mg/week in recently diagnosed PMR patients. Methods We set up a double-blind, randomized, placebo-controlled superiority trial (PMR MODE) to assess the efficacy of MTX 25 mg/week versus placebo in a 1:1 ratio in 100 recently diagnosed PMR patients according to the 2012 EULAR/ACR criteria. All patients will receive prednisolone 15 mg/day, tapered to 0 mg over the course of 24 weeks. In case of primary non-response or disease relapse, prednisolone dose will be temporarily increased. Assessments will take place at baseline, 4, 12, 24, 32, and 52 weeks. The primary outcome is the difference in proportion of patients in GC-free remission at week 52. Discussion No relapsing PMR patients were chosen, since the possible benefits of MTX may not outweigh the risks at low doses and effect modification may occur. Accelerated tapering was chosen in order to more easily identify a GC-sparing effect if one exists. A composite endpoint of GC-free remission was chosen as a clinically relevant endpoint for both patients and rheumatologist and may reduce second order (treatment) effects.

Humoral response to Coronavirus Disease-19 vaccines is dependent on dosage and timing of rituximab in patients with rheumatoid arthritis. Rheumatology (Oxford) 2022; 61:SI175-SI179. [PMID: 35377422 PMCID: PMC8992349 DOI: 10.1093/rheumatology/keac206] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Revised: 03/28/2022] [Indexed: 11/12/2022] Open
Abstract
Objectives Humoral response to vaccines in RA patients treated with rituximab (RTX) in standard dosages (≥1000 mg) is decreased. Ultra-low dosages (500 or 200 mg) may have better response. Also, timing after latest RTX infusion may be an important variable. We aimed to investigate the influence of RTX dosage and timing on response to COVID-19 vaccination in RA patients. Methods A single-centre observational study (n = 196) investigated the humoral response, measured by total Ig anti-COVID-19 assay (positive response ≥1.1), 2–6 weeks after complete COVID-19 vaccination. A multivariable logistic regression model was built to study the effect of RTX dosage and time between latest rituximab and vaccination on response, adjusting for age and methotrexate use. Results After two-dose vaccination, the response rate was significantly better for patients receiving 200 mg (n = 31, 45%) rituximab compared with 1000 mg (n = 98, 26%; odds ratio 3.07, 95% CI 1.14–8.27) and for each additional month between latest rituximab and vaccination (OR 1.67, 1.39–2.01). Conclusion Both increased time between latest rituximab infusion and complete vaccination, and 200 mg as latest dose were associated with a better response to COVID-19 vaccination and should be considered when trying to increase vaccine response after rituximab in RA patients.

Using real-world data to dynamically predict flares during tapering of biological DMARDs in rheumatoid arthritis: development, validation, and potential impact of prediction-aided decisions. Arthritis Res Ther 2022; 24:74. [PMID: 35321739 PMCID: PMC8941811 DOI: 10.1186/s13075-022-02751-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 02/27/2022] [Indexed: 11/22/2022] Open
Abstract
Background Biological disease-modifying antirheumatic drugs (bDMARDs) are effective in the treatment of rheumatoid arthritis. However, as bDMARDs may also lead to adverse events and are expensive, tapering them is of great clinical interest. Tapering according to disease activity-guided dose optimization (DGDO) does not seem to affect long term remission rates, but flares are frequent during this process. Our objective was to develop a model for the prediction of flares during bDMARD tapering using data from routine care and to evaluate its potential clinical impact. Methods We used a joint latent class model to repeatedly predict the probability of a flare occurring within the next 3 months. The model was developed using longitudinal data on disease activity (DAS28) and other routine care data from two clinics. Predictive accuracy was assessed in cross-validation and external validation was performed with data from the DRESS (Dose REduction Strategy of Subcutaneous tumor necrosis factor inhibitors) trial. Additionally, we simulated the reduction in number of flares and bDMARD dose when implementing the model as a decision aid during bDMARD tapering in the DRESS trial. Results Data from 279 bDMARD courses were used for model development. The final model included two latent DAS28-trajectories, bDMARD type and dose, disease duration, and seropositivity. The area under the curve of the final model was 0.76 (0.69–0.83) in cross-validation and 0.68 (0.62–0.73) in external validation. In simulation of prediction-aided decisions, the mean number of flares over 18 months decreased from 1.21 (0.99–1.43) to 0.75 (0.54–0.96). The reduction in he bDMARD dose was mostly maintained, increasing from 54 to 64% of full dose. Conclusions We developed a dynamic flare prediction model, exclusively based on data typically available in routine care. Our results show that using this model to aid decisions during bDMARD tapering may significantly reduce the number of flares while maintaining most of the bDMARD dose reduction. Trial registration The clinical impact of the prediction model is currently under investigation in the PATIO randomized controlled trial (Dutch Trial Register number NL9798).

Abstract
Objective To perform a COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) based Systematic Literature Review of measurement properties of the Polymyalgia Rheumatica Activity Score (PMR-AS). Methods Pubmed, EMBASE, and CINAHL were broadly searched. English full text articles, with (quantitative) data on at least 5 PMR patients using the PMR-AS were selected. Seven hypotheses for construct validity and three for responsiveness, concerning associations with erythrocyte sedimentation rate, physical function, quality of life, clinical disease states, ultrasound, and treatment response, were formulated. Articles usable to assess - COSMIN based - structural validity, internal consistency, reliability, measurement error, or hypotheses on construct validity or responsiveness were selected and assessed based on COSMIN criteria. Results From the 26 articles using the PMR-AS we were able to use 12 articles. Structural validity, internal consistency, construct validity, and responsiveness were assessed in one, two, eight, and three articles respectively. Insufficient evidence was found to confirm structural validity and internal consistency. No data was found on reliability or measurement error. Although 60% and 67% of hypotheses tested for construct validity and responsiveness were confirmed respectively, there was insufficient evidence to meet criteria for good measurement properties. Conclusion Whilst there is some promising evidence for construct validity and responsiveness of the PMR-AS, it is lacking for other properties and overall falls short of criteria for good measurement properties. Therefore, further research is needed to assess its role in clinical research and care.

Abstract
BACKGROUND Biologics for psoriasis are registered in standard dosages. In patients with low disease activity, reduction of the dose by interval prolongation can prevent overtreatment, and lower risks and costs. However, fear for increased anti-drug antibody (ADA) formation due to interval prolongation of biologics is an important barrier. OBJECTIVE To investigate the course of serum drug concentrations, ADA levels, and predictors for successful dose reduction of adalimumab, ustekinumab, and etanercept for psoriasis. METHODS Patients were randomized to dose reduction (DR) or usual care (UC) and followed for one year. The course and extent of detectable ADA levels were expressed as proportions/relative risks for DR vs. UC. Association of baseline characteristics with successful tapering was investigated with log-binomial regression analysis. RESULTS In total, 118 patients were included. In adalimumab-treated patients, no significant difference in the proportion of patients with relevant ADA levels in DR vs. UC was seen. For ustekinumab, relevant ADA development was absent in both groups. Baseline trough levels were not predictive for successful DR. CONCLUSIONS Immunogenicity may not increase by interval prolongation in psoriasis patients with low disease activity. This pilot provides important and reassuring insight into the pharmacological changes after dose tapering of adalimumab, etanercept, and ustekinumab.

Abstract
ABSTRACT
Objective
Whole-body Positron Emission Tomography with CT-scanning using fluorine-18 fluorodeoxyglucose (18F-FDG) is occasionally used in rheumatoid arthritis (RA) patients to detect arthritis. FDG-PET/CT might also detect malignancies, but the amount of incidental findings and the number of relevant malignant disease that could be missed are currently unknown. We aimed to study the malignancy screening performance of whole-body FDG-PET/CT in longstanding RA patients with low disease activity.
Methods
FDG-PET/CT-scanning was done in the intervention arm of the Dose REduction Strategy of Subcutaneous TNF-inhibitors (DRESS) study, a randomized controlled trial on dose-tapering of biological Disease Modifying Anti-Rheumatic Drugs (bDMARDs). The reference standard was clinical diagnosis of malignancy during the 3 year follow-up of the study. Prevalence of extra-articular abnormalities, follow-up, and treatments were summarized post-hoc.
Results
121 scans were made in 79 patients. Extra-articular abnormalities were found in 59/121 (49%) scans, resulting in additional diagnostic procedures in 21/79 (26.6%) patients. Nine patients (7.4%) were suspected of malignancy, none turned out to be malignant. Six clinical malignancies that developed during follow-up were all negative on baseline FDG-PET/CT.
Conclusion
Whole-body FDG-PET/CT-scanning used in RA patients for imaging of arthritis results in frequent incidental extra-articular findings, while some who apparently had normal scans also developed malignancies.

Abstract
Patients with inflammatory rheumatic diseases (IRDs) do not have an increased risk for coronavirus disease 2019 (COVID‐19) compared with the general population. However, it remains uncertain whether subgroups of patients with IRD using different immunosuppressive antirheumatic drugs carry a higher risk for severe COVID‐19 compared with other patients with IRD. The aim of this study is to identify risk factors for severe COVID‐19, requiring hospitalization in patients with IRD. This is a multicenter nested case control study conducted in the Netherlands. Cases are hospital known patients with IRD requiring hospitalization for COVID‐19 between March 1, 2020, and May 31, 2020. Controls are hospital known patients with IRD not requiring hospitalization for COVID‐19 in this period, included at a 4:1 ratio. Patient, disease, and treatment characteristics were extracted from electronic medical records and a questionnaire. Potential risk factors were analyzed using unconditional logistic regression, corrected for confounders and multiple testing. Eighty‐one cases and 396 controls were included. General risk factors of older age and obesity apply to patients with IRD as well (odds ratio (OR) for age ≥ 75 3.5, 95% confidence interval (CI) 1.9–6.3, OR for body mass index ≥ 40 4.5, 95% CI 1.5–14). No significantly increased ORs for COVID‐19 hospitalization were found for any antirheumatic agent or IRD. A protective effect was found for use of methotrexate (OR 0.53, 95% CI 0.31–0.92). In conclusion, similar to the general population, elderly and obese patients with IRD have a higher risk for hospitalization for COVID‐19. We did not identify a specific antirheumatic agent or IRD to increase the risk of COVID‐19 hospitalization in patients with IRD, except for a possible protective effect of methotrexate.

Abstract
OBJECTIVES The REDO trial showed that ultra-low dose rituximab (500 mg or 200 mg) was similarly effective in the majority of rheumatoid arthritis (RA) patients. This pre-planned secondary analysis investigates 1) associations between rituximab dosage, drug levels, anti-drug antibodies (ADA) and B cell counts and 2) the predictive value of pharmacokinetic and -dynamic parameters, patient, disease and treatment characteristics in relation to response to ultra-low dose rituximab. METHODS For 140 RA patients from the REDO trial, differences in drug levels, ADA and B cell counts were examined at baseline, three and six months after dosing. Treatment response was defined as absence of flare and no extra rituximab or > 1 glucocorticoid injection received during follow-up. The association between potential predictors and response was investigated using logistic regression analyses. RESULTS Lower doses of rituximab resulted in lower drug levels but did not significantly affect ADA levels and B cell counts. 3 (10.7%), 12 (20.7%) and 7 (13.0%) patients failed to meet response-criteria in respectively the 1000 mg, 500 mg and 200 mg group. Drug levels, ADA and B cell counts as well as patient, disease and treatment characteristics were not predictive for response to ultra-low dose rituximab. CONCLUSION Results of this study further support that continued treatment with 500 or 200 mg rituximab is similarly effective as 1000 mg in RA patients doing well on rituximab. These results, combined with absence of clinical dose response relation in the original REDO study, suggest that 200 mg rituximab is not yet the lowest effective rituximab retreatment dose in RA.

Abstract
We aimed to validate the association of 28 GWAS-identified genetic variants for response to TNF inhibitors (TNFi) in a discovery cohort of 1361 rheumatoid arthritis (RA) patients monitored in routine care and ascertained through the REPAIR consortium and DANBIO registry. We genotyped selected markers and evaluated their association with response to TNFi after 6 months of treatment according to the change in disease activity score 28 (ΔDAS28). Next, we confirmed the most interesting results through meta-analysis of our data with those from the DREAM cohort that included 706 RA patients treated with TNFi. The meta-analysis of the discovery cohort and DREAM registry including 2067 RA patients revealed an overall association of the LINC02549rs7767069 SNP with a lower improvement in DAS28 that remained significant after correction for multiple testing (per-allele ORMeta=0.83, PMeta=0.000077; PHet=0.61). In addition, we found that each copy of the LRRC55rs717117G allele was significantly associated with lower improvement in DAS28 in rheumatoid factor (RF)-positive patients (per-allele ORMeta=0.67, P=0.00058; PHet=0.06) whereas an opposite but not significant effect was detected in RF-negative subjects (per-allele ORMeta=1.38, P=0.10; PHet=0.45; PInteraction=0.00028). Interestingly, although the identified associations did not survive multiple testing correction, the meta-analysis also showed overall and RF-specific associations for the MAFBrs6071980 and CNTN5rs1813443 SNPs with decreased changes in DAS28 (per-allele ORMeta_rs6071980 = 0.85, P=0.0059; PHet=0.63 and ORMeta_rs1813443_RF+=0.81, P=0.0059; PHet=0.69 and ORMeta_rs1813443_RF-=1.00, P=0.99; PHet=0.12; PInteraction=0.032). Mechanistically, we found that subjects carrying the LINC02549rs7767069T allele had significantly increased numbers of CD45RO+CD45RA+ T cells (P=0.000025) whereas carriers of the LINC02549rs7767069T/T genotype showed significantly increased levels of soluble scavengers CD5 and CD6 in serum (P=0.00037 and P=0.00041). In addition, carriers of the LRRC55rs717117G allele showed decreased production of IL6 after stimulation of PBMCs with B burgdorferi and E coli bacteria (P=0.00046 and P=0.00044), which suggested a reduced IL6-mediated anti-inflammatory effect of this marker to worsen the response to TNFi. In conclusion, this study confirmed the influence of the LINC02549 and LRRC55 loci to determine the response to TNFi in RA patients and suggested a weak effect of the MAFB and CNTN5 loci that need to be further investigated.

Abstract
Objectives Research on effectiveness and cost‐effectiveness of longstanding exercise therapy in patients with axial SpondyloArthritis (axSpA) or Rheumatoid Arthritis (RA) is scarce, and mainly concerned patients with a relatively favorable health status. We aim to evaluate the effectiveness and cost‐effectiveness of longstanding exercise therapy compared to usual care in the subgroup of patients with axSpA or RA and severe limitations in functioning. Methods In two separate, parallel randomized controlled trials the effectiveness and cost‐effectiveness of longstanding, active exercise therapy (52 weeks) compared with usual care (1:1) will be evaluated. The longstanding, active exercise therapy will focus on improving individual limitations in daily activities and participation and will be given by a trained physical therapist in the vicinity of the participant. For each diagnosis, 215 patients with severe limitations in activities and participation will be included. Assessments are performed at baseline, 12, 26, and 52 weeks. The primary outcome measure of effectiveness is the individual level of functioning (activities and participation), as measured with the Patient‐Specific Complaints instrument at 52 weeks. For cost‐effectiveness analyses, the EuroQol (EQ‐5D‐5L) and questionnaires on healthcare use and productivity will be administered. The economic evaluation will be a cost‐utility analysis from a societal perspective. After 52 weeks, the patients in the usual care group are offered longstanding, active exercise therapy as well. Follow‐up assessments are done at 104, 156, and 208 weeks. Conclusion The results of these studies will provide insights in the effectiveness and cost‐effectiveness of longstanding exercise therapy in the subgroup of axSpA and RA patients with severe functional limitations.

METHODS Patients in the tapering arm of the DRESS study, a randomized controlled trial on TNFi tapering in RA, underwent FDG-PET before tapering (baseline) and after maximal tapering. 48 joints per scan were scored: 1) visually (FDG-avid joint (FAJ) y/n), 2) quantitatively (maximal and mean standardized uptake values (SUVmax and SUVmean)). Interobserver agreement was calculated in 10 patients at baseline. Quantitative and visual FDG-PET scores were investigated for: 1) (multilevel) association with clinical parameters both on joint and patient level and 2) predictive value at baseline and change between baseline and maximal tapering (delta) for successful tapering and discontinuation at 18 months. RESULTS 79 patients underwent FDG-PET. For performance of identification of FAJs on PET, Cohen's kappa was 0.49 (0.35-0.63). For SUVmax and SUVmean, ICCs were 0.80 (0.77-0.83) and 0.96 (0.9-1.0), respectively. On joint level, swelling was significantly associated with SUVmax and SUVmean (B coefficients with 95%CI 1.0 (0.73-1.35) and 0.2 (0.08-0.32) respectively). On patient level only correlation with acute phase reactants was found. FDG-PET scores were not predictive for successful tapering or discontinuation. CONCLUSIONS Quantitative FDG-PET arthritis scoring in RA patients with low disease activity is reliable and has some construct validity. However, no predictive values were found for FDG-PET parameters for successful tapering and/or discontinuation of TNFi.

Abstract
Objectives We investigated the effect of disease activity-guided dose optimization (DAGDO) of TNF inhibitor (TNFi) on disease activity and TNFi dose in PsA and axial spondyloarthritis (axSpA) patients with low disease activity (LDA). Methods A retrospective cohort study was conducted in PsA and axSpA patients doing well on TNFi and eligible for TNFi DAGDO. Three different treatment periods were defined: (i) full dose continuation period, (ii) TNFi DAGDO period, and (iii) period with stable TNFi dose after DAGDO. A mixed-model analysis was used to estimate mean Disease Activity Score 28-joint count CRP (DAS28-CRP) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) during these periods, and a mean percentage of the daily defined dose (%DDD) was calculated as secondary outcome. Results Three hundred and twenty-four patients (153 PsA and 171 axSpA) were included, with a mean of 6.5 DAS28-CRP and 6.4 BASDAI measurements and a median follow-up duration of 46 and 44 months, respectively. A corrected difference of 0.06 (95% CI: −0.09, 0.21) in mean DAS28-CRP was found for the TNFi DAGDO period and 0.03 (95% CI: −0.14, 0.20) for the period with stable TNFi dose, compared with full dose continuation period. Differences for BASDAI were 0.03 (95% CI: −0.21, 0.27) and 0.05 (95% CI: −0.24, 0.34), respectively. The mean %DDD for the three treatment periods was for PsA 108%, 62% and 78%, and for axSpA 108%, 62% and 72%, respectively. Conclusion DAGDO of TNFi reduces drug exposure and has no negative effects on disease activity in PsA and axSpA patients compared with full dose continuation.

Abstract
Effective patient-provider communication is crucial to promote shared decision-making. However, it is unclear how to explain treatment changes to ensure patient acceptance, such as when transitioning from a bio-originator to a biosimilar. This review investigates communication strategies used to educate patients on transitioning to biosimilars and explores whether the willingness to transition and treatment persistence differs for the delivery (verbal or written) and the amount of information provided. MEDLINE, Embase, Scopus, and relevant conference databases were systematically searched. Communication strategies from 33 studies (88% observational cohort studies) published from 2012 to 2020 were synthesized and willingness to transition, persistence, and subjective adverse events explored. Patients only received information verbally in 11 studies. The remaining 22 studies also provided written information. Cost-saving was the main reason provided for the transition. Patients were most willing to transition when receiving written and verbal information (χ2 = 5.83, p = .02) or written information that only addressed a few (3-5) concerns (χ2 = 16.08, p < .001). There was no significant difference for persistence or subjective adverse events (p's > .05). Few randomized controlled trials have been conducted. Available data shows more willingness to transition when patients received written and verbal information. Initial documents should contain basic information and consultations or telephone calls used to address concerns.

Abstract
OBJECTIVES The aim of this study was to compare the effectiveness and tolerability between oral methotrexate (MTX) and subcutaneous MTX in a large group of rheumatoid arthritis (RA) patients in a real-life setting. METHODS In this retrospective cohort study, adult patients with clinical diagnosis of RA who started MTX treatment (monotherapy or combined with hydroxychloroquine), either started with oral or subcutaneous MTX. The primary outcome was superiority testing of between group difference in change in DAS28CRP between baseline and 3-6 months, and subsequent non inferiority testing (NI margin 0.6) analyses in case of non-superiority. Secondary outcomes included MTX dose, side effects, laboratory abnormalities, and use of comedication. RESULTS 640 RA patients were included: 259 started with oral MTX and 381 with subcutaneous. There was no significant difference in ΔDAS28CRP, after adjusting for confounding, 0.13 (95%-CI: -0.14, 0.40), and oral MTX strategy was non inferior to subcutaneous. The mean MTX dose was slightly lower for the oral strategy (18.0 SD6.9 vs 19.9 SD8.2, p= 0.002), which was accompanied by a lower cumulative incidence of adverse events (41% vs 52%, p= 0.005). No differences were seen in use of other comedication. CONCLUSIONS Starting with oral MTX in RA in a real-life setting is non inferior to a subcutaneous MTX treatment with regard to disease activity control, at least when used in dosages up to 25 mg and on a background of HCQ cotreatment and a treat-to-target approach. In addition, tolerability was better. This supports the strategy of starting with oral MTX.

Abstract
Background Rheumatoid arthritis (RA) patients have an increased cardiovascular (CV) risk. Here, we aimed to investigate whether gender and age are contributing to the misclassification of CV risk in RA patients. Methods Prospectively collected data on cardiovascular risk factors and incident events from the Nijmegen inception cohort were analyzed, with up to 10 years follow-up. Original as well as the EULAR-modified (M)_SCORE algorithms were used to calculate CV risk. Patients were stratified in deciles according to predicted risk; the Hosmer-Lemeshow test was used to check concordance between observed and predicted risk, in subgroups of gender and age. Results There were 863 RA patients included with 128 incident CV events. When using SCORE in the whole group, there was evidence of a discrepancy between the predicted and observed CV risk (H-L test p < 0.003), mainly present in the female subgroup (H-L test p < 0.001). Interestingly, 36% of females who developed an event belonged to the low CV risk group, whereas this was just 10% in RA males. When analyzing the subgroups based on age, a discrepancy was present only in the youngest patients (H-L test p < 0.001 in patients < 55 years) consisting of an underestimation of CV risk (5.3% predicted vs. 8.0% observed). Similar results were obtained when the M_SCORE was applied. Conclusion CV risk is especially underestimated in female and younger RA patients. This suggests that modifying the weight for the female gender and/or younger age in currently used CV risk algorithms might improve their predictive value in RA, contributing to better CV risk management.

Abstract
Importance Biologics revolutionized the treatment of psoriasis. Biologics are given in a fixed dose, but lower doses might be possible. Objective To investigate whether dose reduction (DR) of biologics in patients with stable psoriasis is noninferior to usual care (UC). Design, Setting, and Participants This pragmatic, open-label, prospective, controlled, noninferiority randomized clinical trial was conducted from March 1, 2016, to July 22, 2018, at 6 dermatology departments in the Netherlands. A total of 120 patients with plaque psoriasis and stable low disease activity who were receiving treatment with adalimumab, etanercept, or ustekinumab were studied. Interventions Patients were randomized 1:1 to DR (n = 60) or UC (n = 60). In the DR group, injection intervals were prolonged stepwise, leading to 67% and 50% of the original dose. Main Outcomes and Measures The primary outcome was between-group difference in disease activity corrected for baseline at 12 months compared with the predefined noninferiority margin of 0.5. Secondary outcomes were Psoriasis Area and Severity Index (PASI) score and health-related quality of life (including Dermatology Life Quality Index [DLQI] and Medical Outcomes Study 36-Item Short Form Health Survey scores), proportion of patients with short and persistent flares (defined as PASI and/or DLQI scores >5 for ≥3 months), and proportion of patients with successful dose tapering. Results Of 120 patients (mean [SD] age, 54.0 [13.2] years; 82 [68%] male), 2 patients were lost to follow-up, 2 patients had a protocol violation, and 5 patients had a protocol deviation, leaving 111 patients for the per-protocol analysis (53 in the DR group and 58 in the UC group). The median PASI scores at month 12 were 3.4 (interquartile range [IQR], 2.2-4.5) in the DR group and 2.1 (IQR, 0.6-3.6) in the UC group (mean difference, 1.2; 95% CI, 0.7-1.8). This indicates that noninferiority was not demonstrated for DR compared to UC. The median DLQI score at month 12 was 1.0 (IQR, 0.0-2.0) in the DR group and 0.0 (IQR, 0.0-2.0) in the UC group (mean difference, 0.8; 95% CI, 0.3-1.3), indicating noninferiority for DR compared with UC. No significant difference was found regarding persistent flares between groups (n = 5 in both groups). Twenty-eight patients (53%; 95% CI, 39%-67%) in the DR group tapered their dose successfully at 12 months. No severe adverse events related to the intervention occurred. Conclusions and Relevance In this trial, noninferiority was not demonstrated for DR of adalimumab, etanercept, and ustekinumab based on the PASI in patients with psoriasis compared with UC with the chosen noninferiority margin. However, the strategy was noninferior based on the DLQI. Dose tapering did not lead to persistent flares or safety issues. Trial Registration ClinicalTrials.gov Identifier: NCT02602925.

Abstract
A dose reduction strategy for adalimumab, etanercept and ustekinumab in patients with psoriasis who have stable and low disease activity has recently been compared with usual care in the CONDOR study (CONtrolled DOse Reduction) of biologics in patients with psoriasis with low disease activity. The aim of the current study was to perform a cost-utility analysis with a 12-month time horizon alongside this trial, using prospectively measured healthcare costs and quality-adjusted life years, based on Short-Form Six-Dimension utilities. Bootstrap analyses were used to calculate the decremental cost-utility ratio and the incremental net monetary benefit. The dose reduction strategy resulted in a mean cost saving of €3,820 (95th percentile –€3,099 to –€4,509) per patient over a period of 12 months. There was an 83% chance that dose reduction would result in a reduction in quality adjusted life years (mean –0.02 (95th percentile –0.06 to 0.02). In conclusion, dose reduction of biologics resulted in substantial cost savings with an acceptable reduction in quality of life.

Abstract
Severe infectious diseases result in an increased volume of distribution. Renal function is usually impaired, but can in fact be increased early in the course of the disease. In renally cleared drugs with a small therapeutic index a dose reduction should take place or these medications should be temporarily discontinued. Renally cleared antibiotics may be subject to subtherapeutic levels of antibiotics, especially early in the course of the disease. Diuretics and RAAS inhibitors should usually be interrupted during acute illness; bèta-blockers should be continued. Statins can usually be continued. Paracetamol can usually be prescribed. NSAIDs, however, are almost always contra-indicated. Patients with chronic use of corticosteroids should receive a stress dose. There is no evidence to support discontinuing immunosuppressants. Platelet aggregation inhibitors and directly acting oral anticoagulants are continued, whereas coumarins should be monitored vigorously or substituted for low molecular weight heparins.

Abstract
Extra-intestinal manifestations (EIMs) of inflammatory bowel disease (IBD) occur
frequently and contribute to morbidity and reduced quality of life. The
musculoskeletal, ocular and cutaneous organ systems are frequently involved in
IBD-related EIMs. By focusing on manifestations involving the joints, skin and
eyes, this review will discuss the most common clinically relevant and
burdensome EIMs that affect IBD patients, and strives for early recognition,
adequate treatment and timely referral. For this purpose, we aimed to create a
comprehensive overview on this topic, with the main focus on the treatment of
reactive and associated EIMs, including spondyloarthropathies, pyoderma
gangrenosum, erythema nodosum, psoriasis and anterior uveitis. The recently
developed biologicals enable simultaneous treatment of inflammatory disorders.
This review can be used as a helpful guide in daily clinical practice for
physicians who are involved in the treatment of IBD patients.
