27846761 Prognostic factors of methotrexate-associated lymphoproliferative disorders associated wit 2017 Sep OBJECTIVES: To determine prognostic factors of methotrexate-associated lymphoproliferative disorder (MTX-LPD) and evaluate the efficacy and safety of biological therapy in rheumatoid arthritis (RA) complicated with MTX-LPD. METHODS: Thirty RA patients who developed MTX-LPD were investigated in this study. We compared the clinical and laboratory parameters of patients who achieved regression of LPD by MTX withdrawal with those who required chemotherapy and evaluated the clinical course of RA after LPD development. RESULTS: Twenty-three patients (76.7%) achieved regression of LPD by MTX withdrawal. Chemotherapy-free patients had a tendency of shorter RA duration (13.1 vs. 22.0 years, p = 0.108) and higher doses of MTX at LPD diagnosis (8.0 vs. 5.3 mg/w, p = 0.067) than patients who required chemotherapy. A significantly higher positive rate of peripheral blood Epstein-Barr virus (EBV)-DNA was observed in the chemotherapy-free group (9/9 vs. 0/3, p = 0.0002). Of 15 patients that received biological agents after LPD development, 14 patients (93.3%) demonstrated an improved disease activity of RA and persistent remission of LPD, whereas only one patient experienced relapse of LPD during tocilizumab therapy. CONCLUSIONS: Peripheral blood EBV-DNA positivity is a potential prognostic marker of better outcome in MTX-LPD. Biological agents could be an option for the treatment of RA patients with MTX-LPD.
28484154 [Spontaneous regression of methotrexate-related diffuse large B-cell lymphoma following bl 2017 A 71-year-old woman who had been treated with methotrexate (MTX) and prednisolone for rheumatoid arthritis since 2010 presented with hematuria. Cystitis was diagnosed. Chest and abdominal CT images revealed a bladder tumor, with lung and bilateral adrenal metastases. Transurethral resection of the bladder tumor (TUR-BT) confirmed these findings in September 2014. Histological findings of the bladder included large atypical lymphoid cells indicating diffuse large B-cell lymphoma. After TUR-BT, CT imaging showed that the tumor had shrunk. Still, MTX was continued. She was diagnosed with MTX-related lymphoproliferative disorders in November 2014 and MTX was discontinued. Fluorodeoxyglucose-positron emission tomography on March 2015 showed a complete response.
29051108 A Bayesian model that jointly considers comparative effectiveness research and patients' p 2018 Jan OBJECTIVES: The objective of the study was to estimate the preferred treatment for early rheumatoid arthritis using a novel Bayesian approach that jointly considers patients' preferences and comparative effectiveness research. STUDY DESIGN AND SETTING: We estimated the preferred treatment using patients' preferences measured in a discrete-choice experiment to apply weights to benefit and harm outcomes from a network meta-analysis and other considerations (dosing, rare adverse events). Using Bayesian analyses, we considered the variability in patients' preferences and the imprecision in both patients' preferences and the treatment effects; all key considerations in the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS: We estimated that most patients in our population would prefer triple therapy as initial treatment (78%) or after an inadequate response to methotrexate (62%). The probability of choosing triple therapy as initial treatment was further from 50% (the point of indifference) for more patients, making our prediction more confident, and suggesting a stronger recommendation could be made. After an inadequate response to methotrexate, the choice was more split, suggesting a decision aid may be helpful. CONCLUSION: Using a novel approach, we estimated that many patients with early rheumatoid arthritis may prefer triple therapy to other treatment options, in contrast to existing guidelines. This offers an approach that may help inform Grading of Recommendations Assessment, Development, and Evaluation treatment recommendations.
28554192 Triple Therapy Versus Biologic Therapy for Active Rheumatoid Arthritis: A Cost-Effectivene 2017 Jul 4 BACKGROUND: The RACAT (Rheumatoid Arthritis Comparison of Active Therapies) trial found triple therapy to be noninferior to etanercept-methotrexate in patients with active rheumatoid arthritis (RA). OBJECTIVE: To determine the cost-effectiveness of etanercept-methotrexate versus triple therapy as a first-line strategy. DESIGN: A within-trial analysis based on the 353 participants in the RACAT trial and a lifetime analysis that extrapolated costs and outcomes by using a decision analytic cohort model. DATA SOURCES: The RACAT trial and sources from the literature. TARGET POPULATION: Patients with active RA despite at least 12 weeks of methotrexate therapy. TIME HORIZON: 24 weeks and lifetime. PERSPECTIVE: Societal and Medicare. INTERVENTION: Etanercept-methotrexate first versus triple therapy first. OUTCOME MEASURES: Incremental costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). RESULTS OF BASE-CASE ANALYSIS: The within-trial analysis found that etanercept-methotrexate as first-line therapy provided marginally more QALYs but accumulated substantially higher drug costs. Differences in other costs between strategies were negligible. The ICERs for first-line etanercept-methotrexate and triple therapy were $2.7 million per QALY and $0.98 million per QALY over 24 and 48 weeks, respectively. The lifetime analysis suggested that first-line etanercept-methotrexate would result in 0.15 additional lifetime QALY, but this gain would cost an incremental $77 290, leading to an ICER of $521 520 per QALY per patient. RESULTS OF SENSITIVITY ANALYSIS: Considering a long-term perspective, an initial strategy of etanercept-methotrexate and biologics with similar cost and efficacy is unlikely to be cost-effective compared with using triple therapy first, even under optimistic assumptions. LIMITATION: Data on the long-term benefit of triple therapy are uncertain. CONCLUSION: Initiating biologic therapy without trying triple therapy first increases costs while providing minimal incremental benefit. PRIMARY FUNDING SOURCE: The Cooperative Studies Program, Department of Veterans Affairs Office of Research and Development, Canadian Institutes for Health Research, and an interagency agreement with the National Institutes of Health-American Recovery and Reinvestment Act.
28407841 Cardiovascular Comorbidity in Inflammatory Rheumatological Conditions. 2017 Mar 24 BACKGROUND: Approximately 1.5 million adults in Germany suffer from an inflammatory rheumatological condition. The most common among these are rheumatoid arthritis and spondyloarthritis-above all axial spondyloarthritis, including ankylosing spondylitis (Bekhterev's disease) and psoriatic arthritis. These systemic inflammatory diseases often affect the heart as well. METHODS: This review is based on pertinent articles retrieved by a selective literature search, on current European guidelines, and on the authors' clinical experience. RESULTS: Rheumatic inflammation of cardiac structures can manifest itself as pericarditis, myocarditis, or endocarditis. The heart valves and the intracardiac conduction system can be affected as well, leading to AV block. Functional sequelae, e.g., congestive heart failure, can arise as a consequence of any inflammatory rheumatic disease. The long-term mortality of rheumatic diseases is elevated predominantly because of the increased risk for cardiovascular comorbidities. The cardiovascular risk profile should therefore be re-evaluated regularly (e.g., at 5-year intervals) in cooperation with the patient's primary care physician. The cardiovascular manifestations of rheumatic disease, such as pericarditis, myocarditis, and vasculitis, are treated initially with high-dose glucocorticoids and then over the long term with maintenance drugs such as methotrexate and azathioprine. Biological agents are sometimes used as well. CONCLUSION: In patients with inflammatory rheumatic diseases, the elevated cardiovascular risk should be kept in mind and preventive measures should be initiated early. This subject should be further studied in controlled trials so that the treatment options for patients with cardiac involvement can be evaluated.
28380678 Clinicopathological analysis of methotrexate-associated lymphoproliferative disorders: Com 2017 Jun Patients with rheumatoid arthritis often develop methotrexate-associated lymphoproliferative disorders (MTX-LPD) during MTX treatment. MTX-LPD occasionally regresses spontaneously after simply discontinuing MTX treatment. In patients without spontaneous regression, additional chemotherapy is required to avoid disease progression. However, the differences between spontaneous and non-spontaneous regression have yet to be elucidated. To clarify the factors important for spontaneous regression, we analyzed the clinicopathological features of 51 patients with rheumatoid arthritis who developed MTX-LPD (diffuse large B-cell lymphoma [DLBCL]-type [n = 34] and classical Hodgkin lymphoma [CHL]-type [n = 17]). We examined the interval from MTX discontinuation to the administration of additional chemotherapy. The majority of DLBCL-type MTX-LPD patients (81%) exhibited remission with MTX discontinuation alone. In contrast, the majority of CHL-type MTX-LPD patients (76%) required additional chemotherapy. This difference was statistically significant (P = 0.001). However, overall survival was not significantly different between DLBCL-type and CHL-type (91% vs 94%, respectively; P > 0.05). Thus, the morphological differences in the pathological findings of MTX-LPD may be a factor for spontaneous or non-spontaneous regression after discontinuation of MTX.
28282491 Biologics or tofacitinib for people with rheumatoid arthritis unsuccessfully treated with 2017 Mar 10 BACKGROUND: Biologic disease-modifying anti-rheumatic drugs (DMARDs: referred to as biologics) are effective in treating rheumatoid arthritis (RA), however there are few head-to-head comparison studies. Our systematic review, standard meta-analysis and network meta-analysis (NMA) updates the 2009 Cochrane overview, 'Biologics for rheumatoid arthritis (RA)' and adds new data. This review is focused on biologic or tofacitinib therapy in people with RA who had previously been treated unsuccessfully with biologics. OBJECTIVES: To compare the benefits and harms of biologics (abatacept, adalimumab, anakinra, certolizumab pegol, etanercept, golimumab, infliximab, rituximab, tocilizumab) and small molecule tofacitinib versus comparator (placebo or methotrexate (MTX)/other DMARDs) in people with RA, previously unsuccessfully treated with biologics. METHODS: On 22 June 2015 we searched for randomized controlled trials (RCTs) in CENTRAL, MEDLINE, and Embase; and trials registries (WHO trials register, Clinicaltrials.gov). We carried out article selection, data extraction, and risk of bias and GRADE assessments in duplicate. We calculated direct estimates with 95% confidence intervals (CI) using standard meta-analysis. We used a Bayesian mixed treatment comparison (MTC) approach for NMA estimates with 95% credible intervals (CrI). We converted odds ratios (OR) to risk ratios (RR) for ease of understanding. We have also presented results in absolute measures as risk difference (RD) and number needed to treat for an additional beneficial outcome (NNTB). Outcomes measured included four benefits (ACR50, function measured by Health Assessment Questionnaire (HAQ) score, remission defined as DAS < 1.6 or DAS28 < 2.6, slowing of radiographic progression) and three harms (withdrawals due to adverse events, serious adverse events, and cancer). MAIN RESULTS: This update includes nine new RCTs for a total of 12 RCTs that included 3364 participants. The comparator was placebo only in three RCTs (548 participants), MTX or other traditional DMARD in six RCTs (2468 participants), and another biologic in three RCTs (348 participants). Data were available for four tumor necrosis factor (TNF)-biologics: (certolizumab pegol (1 study; 37 participants), etanercept (3 studies; 348 participants), golimumab (1 study; 461 participants), infliximab (1 study; 27 participants)), three non-TNF biologics (abatacept (3 studies; 632 participants), rituximab (2 studies; 1019 participants), and tocilizumab (2 studies; 589 participants)); there was only one study for tofacitinib (399 participants). The majority of the trials (10/12) lasted less than 12 months.We judged 33% of the studies at low risk of bias for allocation sequence generation, allocation concealment and blinding, 25% had low risk of bias for attrition, 92% were at unclear risk for selective reporting; and 92% had low risk of bias for major baseline imbalance. We downgraded the quality of the evidence for most outcomes to moderate or low due to study limitations, heterogeneity, or rarity of direct comparator trials. Biologic monotherapy versus placeboCompared to placebo, biologics were associated with clinically meaningful and statistically significant improvement in RA as demonstrated by higher ACR50 and RA remission rates. RR was 4.10 for ACR50 (95% CI 1.97 to 8.55; moderate-quality evidence); absolute benefit RD 14% (95% CI 6% to 21%); and NNTB = 8 (95% CI 4 to 23). RR for RA remission was 13.51 (95% CI 1.85 to 98.45, one study available; moderate-quality evidence); absolute benefit RD 9% (95% CI 5% to 13%); and NNTB = 11 (95% CI 3 to 136). Results for withdrawals due to adverse events and serious adverse events did not show any statistically significant or clinically meaningful differences. There were no studies available for analysis for function measured by HAQ, radiographic progression, or cancer outcomes. There were not enough data for any of the outcomes to look at subgroups. Biologic + MTX versus active comparator (MTX/other traditional DMARDs)Compared to MTX/other traditional DMARDs, biologic + MTX was associated with a clinically meaningful and statistically significant improvement in ACR50, function measured by HAQ, and RA remission rates in direct comparisons. RR for ACR50 was 4.07 (95% CI 2.76 to 5.99; high-quality evidence); absolute benefit RD 16% (10% to 21%); NNTB = 7 (95% CI 5 to 11). HAQ scores showed an improvement with a mean difference (MD) of 0.29 (95% CI 0.21 to 0.36; high-quality evidence); absolute benefit RD 9.7% improvement (95% CI 7% to 12%); and NNTB = 5 (95% CI 4 to 7). Remission rates showed an improved RR of 20.73 (95% CI 4.13 to 104.16; moderate-quality evidence); absolute benefit RD 10% (95% CI 8% to 13%); and NNTB = 17 (95% CI 4 to 96), among the biologic + MTX group compared to MTX/other DMARDs. There were no studies for radiographic progression. Results were not clinically meaningful or statistically significantly different for withdrawals due to adverse events or serious adverse events, and were inconclusive for cancer. Tofacitinib monotherapy versus placeboThere were no published data. Tofacitinib + MTX versus active comparator (MTX)In one study, compared to MTX, tofacitinib + MTX was associated with a clinically meaningful and statistically significant improvement in ACR50 (RR 3.24; 95% CI 1.78 to 5.89; absolute benefit RD 19% (95% CI 12% to 26%); NNTB = 6 (95% CI 3 to 14); moderate-quality evidence), and function measured by HAQ, MD 0.27 improvement (95% CI 0.14 to 0.39); absolute benefit RD 9% (95% CI 4.7% to 13%), NNTB = 5 (95% CI 4 to 10); high-quality evidence). RA remission rates were not statistically significantly different but the observed difference may be clinically meaningful (RR 15.44 (95% CI 0.93 to 256.1; high-quality evidence); absolute benefit RD 6% (95% CI 3% to 9%); NNTB could not be calculated. There were no studies for radiographic progression. There were no statistically significant or clinically meaningful differences for withdrawals due to adverse events and serious adverse events, and results were inconclusive for cancer. AUTHORS' CONCLUSIONS: Biologic (with or without MTX) or tofacitinib (with MTX) use was associated with clinically meaningful and statistically significant benefits (ACR50, HAQ, remission) compared to placebo or an active comparator (MTX/other traditional DMARDs) among people with RA previously unsuccessfully treated with biologics.No studies examined radiographic progression. Results were not clinically meaningful or statistically significant for withdrawals due to adverse events and serious adverse events, and were inconclusive for cancer.
27748083 Peficitinib, a JAK Inhibitor, in the Treatment of Moderate-to-Severe Rheumatoid Arthritis 2017 Apr OBJECTIVE: To evaluate the efficacy and safety of orally administered once-daily peficitinib in combination with methotrexate (MTX) in patients with moderate-to-severe rheumatoid arthritis (RA) who had an inadequate response to MTX. METHODS: In this multinational, phase IIb, randomized, double-blind, placebo-controlled, dose-ranging trial, patients with RA (n = 378) were treated with peficitinib 25 mg, 50 mg, 100 mg, or 150 mg plus MTX, or matching placebo plus MTX once daily for 12 weeks. The primary end point was the percentage of patients who met the American College of Rheumatology 20% improvement criteria (achieved an ACR20 response) at week 12. RESULTS: ACR20 response rates at week 12 were 43.9%, 61.5% (P < 0.05 versus placebo), 46.4%, 57.7%, and 44.4% in the peficitinib 25 mg, 50 mg, 100 mg, 150 mg, and placebo groups, respectively. Significant decreases from baseline in the Disease Activity Score in 28 joints using the C-reactive protein level were seen in the peficitinib 50 mg (P < 0.05) and 150 mg (P < 0.01) groups compared with placebo at week 12. Overall, the incidence of adverse events (AEs) was similar between peficitinib and placebo. The most common AEs were urinary tract infection (n = 22 [6%]), upper respiratory tract infection (n = 16 [4%]), and diarrhea (n = 16 [4%]). There were 3 cases of herpes zoster infection (2 in the peficitinib 100 mg group and 1 in the 150 mg group) and 2 cases of serious infection (viral infection in the peficitinib 100 mg group and erysipelas in the 150 mg group). CONCLUSION: The ACR20 response rate in the group receiving peficitinib 50 mg plus MTX was significantly different compared with the rate in patients receiving placebo, but there were no apparent dose-dependent responses, and the placebo response rate was high. Peficitinib plus MTX in patients with moderate-to-severe RA was well tolerated, with limited safety signals emerging.
29255968 A surgical case of methotrexate-associated lymphomatoid granuloma. 2018 Jul We reported a surgical case of methotrexate-associated lymphomatoid granuloma. A 69-year-old female had been treated with methotrexate for rheumatoid arthritis for 35 months. The patient underwent partial resection of the right upper pulmonary lobe for lung cancer when she was 67 years old. A nodule was detected in the left lung field on a chest radiograph performed during the postoperative follow-up period. Computed tomography revealed a 28-mm nodule in the lower left pulmonary lobe. A transbronchial biopsy examination did not lead to a diagnosis. The pulmonary nodule subsequently increased in size. We suspected a malignant tumor and performed lower left lobectomy. A pathological examination revealed lymphomatoid granuloma. Finally, the patient was diagnosed with methotrexate-associated lymphomatoid granuloma based on her history of oral methotrexate treatment.
28932117 Multifunctional folate receptor-targeting and pH-responsive nanocarriers loaded with metho 2017 Rheumatoid arthritis (RA) is an autoimmune disease characterized by progressive cartilage and bone destruction. Activated macrophages that overexpress folic acid (FA) receptors play an important role in RA, due to their abundance in inflamed synovial membrane and joints. In an effort to deliver drugs to the inflamed tissues, multifunctional FA receptor-targeting and pH-responsive nanocarriers were developed. They were composed of lipids, polyethylene glycol (PEG)-poly(lactic-co-glycolic acid) (PLGA) forming a hydrophilic shell, FA around the hydrophilic shell as a targeting ligand, and poly(cyclohexane-1,4-diylacetone dimethylene ketal) (PCADK) and PLGA as a hydrophobic core. PCADK also acts as a pH-responsive material. Methotrexate (Mtx) was encapsulated in the nanoparticles, which exhibited pH-responsive release in vitro. Cellular uptake and cytotoxicity experiments revealed that FA-PEG-PLGA/PCADK-lipid nanoparticles loaded with Mtx (FA-PPLNPs) exhibited superior cellular uptake and higher cytotoxicity to activated macrophages than PPLNPs/Mtx. The therapeutic effect of FA-PPLNPs/Mtx in RA was confirmed in an adjuvant-induced arthritis rat model. These results suggest that the multifunctional folate receptor-targeting and pH-responsive nanocarriers are promising for the treatment of RA.
29441860 Suppression of infliximab antibody levels by azathioprine in patients with rheumatoid arth 2017 Feb 1 In rheumatoid arthritis (RA) treatment, the concomitant use of methotrexate has been shown to reduce the incidence of antibodies to infliximab (ATI), on the other hand, it is unclear whether azathioprine can reduce ATI production. We enrolled a total of 10 Japanese adult patients with RA who were treated with infliximab concomitantly with methotrexate or azathioprine. Serum concentrations of infliximab and ATI of these patients were measured. The mean serum infliximab concentrations was 1.6±1.3 μg/ml in patients with methotrexate and 1.0±0.5 μg/ml in patients with azathioprine. Serum ATI concentrations were below the limit of quantitation in 4 of 5 patients in each group. The results from the present study suggest that azathioprine suppresses ATI production.
27913894 Use and effectiveness of tocilizumab among patients with rheumatoid arthritis: an observat 2017 Feb The aims of the present study are to describe the characteristics of rheumatoid arthritis (RA) patients selected for tocilizumab (TCZ), compare the "real-world" effectiveness of TCZ and tumour necrosis factor inhibitors (TNFi) when used as a first biologic and assess the influence of past biologic exposure/concurrent methotrexate (MTX) therapy on post-TCZ treatment outcomes. The British Society for Rheumatology Biologics Register (BSRBR-RA) is a prospective cohort study following RA patients starting biologics in the UK. This includes patients starting TCZ as first or subsequent biologic, alongside biologic-naïve patients starting TNFi. Six-month disease activity and 1-year drug survival were compared between biologic-naïve patients starting TCZ versus TNFi and first-line versus subsequent TCZ users and TCZ users with MTX versus without using regression models adjusted by propensity score. Two hundred seventeen patients started TCZ, and 2419 started TNFi as first biologic. Seven hundred seventy-seven started TCZ after other biologics. First-line TCZ users had a higher prevalence of pulmonary fibrosis and cancer history than TNFi users. The first-line TCZ users were more likely to achieve DAS28 remission at 6 months than first-line TNFi, but other improvement markers were similar. The treatment response at 6 months was similar between subsequent-line TCZ users and first-line users after adjusting for baseline patient differences. Concurrent MTX use was not associated with treatment response in either first- or subsequent-line TCZ users. TCZ has been primarily used as subsequent-line biologic in the UK. When used as first line, the response appears similar to that observed in patients starting TNFi, suggesting that clinical response alone should not decide between initial biologic therapies.
28058538 Factors influencing the choice of first- and second-line biologic therapy for the treatmen 2017 Apr According to international recommendations, the selection of the biologic disease modifying anti-rheumatic drug (bDMARD) for rheumatoid arthritis (RA) is mainly left to the clinician's preference. We analyzed the real-life factors influencing the first-line choice or the switching strategy, focusing on the prescription of abatacept (ABA) or tocilizumab (TCZ) compared to TNFα inhibitors (TNFi). Patients enrolled in the Lombardy Rheumatology Network (LORHEN) Registry after January 1, 2010, when all considered bDMARD agents were available, were included. The population was divided into "first-" and "second-line" bDMARD. We included 1910 patients (first line n = 1264, second line n = 646). Age was higher in ABA or TCZ vs TNFi treated patients (p < 0.0001). Positive latent tuberculosis screening was associated with first-line ABA (p = 0.002). Methotrexate (MTX) combination therapy was lower in the TCZ group (p = 0.02). The type (dyslipidemia, hypertension, pulmonary disease) and the number of comorbidities influenced the choice towards ABA (p = 0.01). Multinomial logistic regression demonstrated that a second-line treatment, higher age, dyslipidemia, pulmonary disease, other comorbidities, and extra-articular RA manifestations were associated with ABA compared to TNFi. TCZ was associated with a second-line treatment, higher age, and more severe disease activity. Stopping the first bDMARD due to adverse events (AE) influenced the choice towards ABA. In real life, higher age and comorbidities influence the choice towards ABA and TCZ compared to TNFi. ABA was preferred in case of suspension of previous treatments due to AE. After failing a first-line TNFi, swapping to a different mechanism of action is more common.
28281458 Biologic treatment for rheumatic disease: real-world big data analysis from the Greek coun 2017 Jul OBJECTIVES: To directly assess the prevalence of inflammatory rheumatic disease under treatment with biologic disease modifying anti-rheumatic drugs (b-DMARDs) and compare treatment patterns between rheumatoid arthritis (RA) and spondyloarthropathy (SpA), including psoriatic arthritis. METHODS: The obligatory country-wide prescription electronic database covering 10.223.000 Greek citizens (95.1% of the population, 99.5% Caucasian), all of whom with fully reinbursed access to b-DMARDs, was used to retrospectively capture all patients under b-DMARDs for RA/SpA between June 2014-May 2015. Age, gender and medications for RA/SpA and co-morbid classical cardiovascular risk factors (hypertension, dyslipidaemia, diabetes) were retrieved and analysed. RESULTS: A total of 9.824 RA (61.2±14.0 years, 79% women) and 9.279 SpA patients (51.4±13.1 years, 41% women) using pharmacy-dispensed prescriptions for b-DMARDs were identified (overall prevalence 0.19%). Tumour necrosis factor inhibitors were used in 73% and 99% of RA and SpA patients, respectively. B-DMARD monotherapy (RA: 18.71%, SpA: 52.11%), b-DMARD switching during 12 months (RA: 7.73%, SpA: 6.26%), and use of methotrexate (RA: 50.25%, SpA: 27.35%) and corticosteroids (RA: 55.8%, SpA: 23.63%) differed between the two patient subgroups. In both subgroups, women received more often than men methotrexate, leflunomide, hydroxychloroquine and corticosteroids, and less often b-DMARD monotherapy. After adjustments for age, gender and concomitant drugs, the probability for anti-hypertensive and lipid-lowering drug prescription was higher in SpA than RA [OR=1.41 (95%CI: 1.29-1.54) and 1.24 (1.14-1.36), respectively, p<0.001], whereas for anti-diabetics it was similar. CONCLUSIONS: In the first country-wide study that examines the characteristics of rheumatic disease patients under b-DMARD we show that their exact prevalence is 0.19%, with RA patients being older by 10 years, only slightly more numerous, and less likely to receive treatment for hypertension and dyslipidaemia than their demographically matched SpA counterparts. Longitudinal studies should assess the implications of these novel findings on the differential financial burden of rheumatic diseases, as well as on cardiovascular morbidity and mortality of these patients.
28655345 Methotrexate-induced Hypersensitivity Pneumonitis appearing after 30 years of use: a case 2017 Jun 28 BACKGROUND: Methotrexate has been implicated in a variety of lung complications, one of which is hypersensitivity pneumonitis. Hypersensitivity pneumonitis most often occurs within the first year of starting low-dose orally administered methotrexate. We present a case of methotrexate-induced hypersensitivity pneumonitis after 30 years of methotrexate use, which is the first case to be reported so far. CASE PRESENTATION: A 77-year-old African American woman with a history of rheumatoid arthritis presented with progressively worsening shortness of breath and nonproductive cough. She was on a daily dose of 2.5 mg of methotrexate that had been orally administered for the last 30 years. A physical examination was significant for fever of 38.2 °C (100.8 °F), tachycardia, bilateral basal crackles, and oxygen saturation of 88% on room air. A laboratory work up was significant for normal white blood cell count, increased eosinophil count of 18.3%, and erythrocyte sedimentation rate of 111 mm/hour. Sputum cultures were negative for any bacterial pathogens including acid-fast bacilli. Influenza and respiratory syncytial viral infection were ruled out. A (1-3)-B-D-glucan assay (Fungitell®) was within normal limits. Pulmonary embolism was ruled out and echocardiography was normal. A chest X-ray showed hazy opacity with prominent reticulation within the upper lung fields bilaterally, right greater than the left with no pleural effusion. Lung computed tomography revealed nonspecific bilateral upper lung opacification. A pulmonary function test was significant for no obstruction, normal maximum voluntary ventilation, and no restriction, with mildly decreased diffusion. Methotrexate was stopped, and our patient was started on prednisone 60 mg orally administered daily with dramatic clinical and radiologic improvement. CONCLUSIONS: Methotrexate-induced hypersensitivity pneumonitis usually occurs in the initial few weeks to months of starting treatment with methotrexate; however, it can occur late during therapy too, and prompt diagnosis is crucial as it is a reversible condition when diagnosed early.
29139090 Tofacitinib: A Review in Rheumatoid Arthritis. 2017 Dec Tofacitinib (Xeljanz(®)) is a potent, selective JAK inhibitor that preferentially inhibits Janus kinase (JAK) 1 and JAK3. In the EU, oral tofacitinib 5 mg twice daily is indicated for the treatment of moderate to severe active rheumatoid arthritis (RA) in adult patients who have responded inadequately to, or who are intolerant of, one or more DMARDs. Several clinical studies of ≤ 24 months' duration showed that tofacitinib monotherapy (as first- or second-line treatment) and combination therapy with a conventional synthetic DMARD (csDMARD; as second- or third-line treatment) was effective in reducing signs and symptoms of disease and improving health-related quality of life (HR-QOL), with benefits sustained during long-term therapy (≤ 96 months). Tofacitinib monotherapy inhibited progression of structural damage in methotrexate-naïve patients during ≤ 24 months' treatment, with beneficial effects also seen in patients receiving tofacitinib plus methotrexate as second-line therapy for 12 months. Tofacitinib was generally well tolerated during ≤ 114 months' treatment, with most adverse events of mild or moderate severity. The tolerability profile of tofacitinib was generally similar to that of biological DMARDs (bDMARDs), with infections and infestations the most common adverse events (AEs) in tofacitinib recipients. However, the incidence of herpes zoster (HZ) was higher with tofacitinib than in the general RA population, although infections were clinically manageable. When added to background methotrexate, tofacitinib was noninferior to adalimumab in terms of efficacy, and both combination therapies had generally similar tolerability profiles. Although additional comparative studies are needed to more definitively position tofacitinib relative to bDMARDs and other targeted synthetic DMARDs, current evidence indicates that oral tofacitinib is a useful option for the treatment of patients with RA.
28153828 Clinical benefit of 1-year certolizumab pegol (CZP) add-on therapy to methotrexate treatme 2017 Aug OBJECTIVES: To investigate the clinical impact of 1-year certolizumab pegol (CZP) therapy added to the first year of 2-year methotrexate (MTX) therapy, compared with 2-year therapy with MTX alone. METHODS: MTX-naïve patients with early rheumatoid arthritis (RA) with poor prognostic factors were eligible to enter Certolizumab-Optimal Prevention of joint damage for Early RA (C-OPERA), a multicentre, randomised, controlled study, which consisted of a 52-week double-blind (DB) period and subsequent 52-week post treatment (PT) period. Patients were randomised to optimised MTX+CZP (n=159) or optimised MTX+placebo (PBO; n=157). Following the DB period, patients entered the PT period, receiving MTX alone (CZP+MTX→MTX; n=108, PBO+MTX→MTX; n=71). Patients who flared could receive rescue treatment with open-label CZP. RESULTS: 34 CZP+MTX→MTX patients and 14 PBO+MTX→MTX patients discontinued during the PT period. From week 52 through week 104, significant inhibition of total modified total Sharp score progression was observed for CZP+MTX versus PBO+MTX (week 104: 84.2% vs 67.5% (p<0.001)). Remission rates decreased after CZP discontinuation; however, higher rates were maintained through week 104 in CZP+MTX→MTX versus PBO+MTX→MTX (41.5% vs 29.3% (p=0.026), 34.6% vs 24.2% (p=0.049) and 41.5% vs 33.1% (p=0.132) at week 104 in SDAI, Boolean and DAS28(erythrocyte sedimentation rate) remission. CZP retreated patients due to flare (n=28) showed rapid clinical improvement. The incidence of overall adverse events was similar between groups. CONCLUSIONS: In MTX-naïve patients with early RA with poor prognostic factors, an initial 1 year of add-on CZP to 2-year optimised MTX therapy brings radiographic and clinical benefit through 2 years, even after stopping CZP. TRIAL REGISTRATION NUMBER: NCT01451203.
28240592 Analysis of non-melanoma skin cancer across the tofacitinib rheumatoid arthritis clinical 2017 Jul OBJECTIVES: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We evaluated the incidence of non-melanoma skin cancer (NMSC) across the tofacitinib RA development programme. METHODS: NMSC events (through August 2013) were identified in patients receiving tofacitinib in two Phase (P)1, eight P2, six P3 and two long-term extension (LTE) studies. In P123 studies, tofacitinib was administered at various doses (1-30 mg twice daily [BID], 20 mg once daily), as monotherapy or with conventional synthetic disease-modifying anti-rheumatic drugs, mainly methotrexate. In LTE studies, patients from qualifying P123 studies received tofacitinib 5 or 10 mg BID. Crude incidence rates (IRs; patients with events/100 patient-years) for first NMSC event were evaluated across doses and over time. RESULTS: In the overall population, comprising data from 18 studies (15,103 patient-years), 83 of 6092 tofacitinib-treated patients had NMSC events. The IR for NMSC (0.55 [95% confidence interval, 0.45-0.69] overall population) was stable up to 84 months of observation. IRs for tofacitinib 5 and 10 mg BID in combined P123 trials were 0.61 (0.34-1.10) and 0.47 (0.24-0.90), respectively. Corresponding IRs for LTE studies were 0.41 (0.26-0.66) and 0.79 (0.60-1.05). CONCLUSIONS: The IR for NMSC across the tofacitinib RA clinical development programme was low and remained stable over time. The IR for NMSC in LTE studies was numerically but not significantly higher with tofacitinib 10 versus 5 mg BID; an inverse dose relationship was observed in P123 trials. Longer follow-up is required to confirm these results.
28598786 Prevalence and risk factors for liver fibrosis detected by transient elastography or shear 2017 Nov OBJECTIVES: Emerging technologies for monitoring subclinical liver fibrosis include transient elastography (TE) and shear wave elastography (SWE). A systematic review was conducted to assess the prevalence and report on predictors of liver fibrosis as detected by these technologies in inflammatory arthritis (IA) patients, including rheumatoid arthritis, spondyloarthritis and juvenile idiopathic arthritis. METHODS: MEDLINE, EMBASE and Web of Science were searched from inception to 06/27/2016 using search terms for IA or DMARDs and TE/SWE. Studies reporting on prevalence and/or risk factors for liver fibrosis as detected by TE/SWE were included. A meta-analysis was not conducted due to study heterogeneity. RESULTS: Seven cross-sectional and three case-control studies were included. The cut-off values to define liver fibrosis ranged from 5.3-8.6 kPa. The prevalence of liver fibrosis in RA detected by TE/SWE ranged from 3-23%, with higher prevalence found in studies using a 5.3kPa cut-off. In two studies fibrosis was reported in 16-17% of PsA patients with no JIA studies identified. Obesity was the most consistently reported independent predictor of fibrosis in three studies. Liver function tests (LFTs) were found to independently predict increased liver stiffness in one study, while cumulative dose of either methotrexate or leflunomide were predictors in two studies. CONCLUSIONS: Methotrexate or leflunomide cumulative dose was not consistently reported as an independent predictor of liver fibrosis; whereas, obesity was more consistently identified. Of note, LFTs did not consistently predict elevated TE/SWE measures. Further studies are needed to evaluate the prevalence and predictors of liver fibrosis and to explore the utility of using TE/SWE in IA patients.
28341765 Quantifying the hepatotoxic risk of alcohol consumption in patients with rheumatoid arthri 2017 Sep BACKGROUND: Patients with rheumatoid arthritis (RA) who take methotrexate (MTX) are advised to limit their alcohol intake due to potential combined hepatotoxicity. However, data are limited to support this. The aim of this study was to quantify the risk of developing abnormal liver blood tests at different levels of alcohol consumption, using routinely collected data from primary care. METHODS: Patients with RA in the Clinical Practice Research Datalink starting MTX between 1987 and 2016 were included. Hepatotoxicity was defined as transaminitis: alanine transaminase or aspartate aminotransferase more than three times the upper limit of normal. Crude rates of transaminitis were calculated per 1000 person-years, categorised by weekly alcohol consumption in units. Cox proportional hazard models tested the association between alcohol consumption and transaminitis univariately, then age and gender adjusted. RESULTS: 11 839 patients were included, with 530 episodes of transaminitis occurring in 47 090 person-years follow-up. Increased weekly alcohol consumption as a continuous variable was associated with increased risk of transaminitis, adjusted HR (95% CI) per unit consumed 1.01 (1.00 to 1.02); consuming between 15 and 21 units was associated with a possible increased risk of hepatotoxicity, while drinking >21 units per week significantly increased rates of transaminitis, adjusted HR (95% CI) 1.85 (1.17 to 2.93). CONCLUSIONS: Weekly alcohol consumption of <14 units per week does not appear to be associated with an increased risk of transaminitis.
