RESUMEN

Objectives: To determine possible differences in serious adverse effects among the 10 currently approved biological and targeted synthetic DMARDs (b/ts-DMARDs) for RA. Methods: Systematic review in bibliographic databases, trial registries and websites of regulatory agencies identified randomized trials of approved b/ts-DMARDs for RA. Network meta-analyses using mixed-effects Poisson regression models were conducted to calculate rate ratios for serious adverse events (SAEs) and deaths between each of the 10 drugs and control (i.e. no b/ts-DMARD treatment), based on subjects experiencing an event in relation to person-years. Confidence in the estimates was assessed by applying the Grading of Recommendations Assessment, Development and Evaluation approach (GRADE). Results: A total of 117 trials (47 615 patients) were included. SAEs were more common with certolizumab compared with abatacept (rate ratio = 1.58, 95% CI: 1.18, 2.14), adalimumab (1.36, 95% CI: 1.02, 1.81), etanercept (1.60, 95% CI: 1.18, 2.17), golimumab (1.45, 95% CI: 1.00, 2.08), rituximab (1.63, 95% CI: 1.16, 2.30), tofacitinib (1.44, 95% CI: 1.03, 2.02) and control (1.45, 95% CI: 1.13, 1.87); and tocilizumab compared with abatacept (1.30, 95% CI: 1.03, 1.65), etanercept (1.31, 95% CI: 1.04, 1.67) and rituximab (1.34, 95% CI: 1.01, 1.78). No other comparisons were statistically significant. Accounting for study duration confirmed our findings for up to 6 months' treatment but not for longer-term treatment (6-24 months). No differences in mortality between b/ts-DMARDs and control were found. Based on the GRADE approach, confidence in the estimates was low due to lack of head-to-head comparison trials and imprecision in indirect estimates. Conclusion: Despite low confidence in the estimates, our analysis found potential differences in rates of SAEs. Our data suggest caution should be taken when deciding among available drugs. Systematic review registration number: PROSPERO CRD42014014842.

RESUMEN

OBJECTIVES: To investigate the association between tobacco smoking and disease activity, treatment adherence and treatment responses among patients with psoriatic arthritis (PsA) initiating the first tumour necrosis factor α inhibitor therapy (TNFi) in routine care. METHODS: Observational cohort study based on the Danish nationwide DANBIO registry. Kaplan-Meier plots, logistic and Cox regression analyses by smoking status (current/previous/never smoker) were calculated for treatment adherence, ACR20/50/70-responses and EULAR-good-response. Additional stratified analyses were performed according to gender and TNFi-subtype (adalimumab/etanercept/infliximab). RESULTS: Among 1388 PsA patients included in the study, 1148 (83%) had known smoking status (33% current, 41% never and 26% previous smokers). Median follow-up time was 1.22 years (IQR 0.44-2.96). At baseline, current smokers had lower Body Mass Index (27 kg/m(2) (23-30)/28 kg/m(2) (24-31)) (median (IQR)), shorter disease duration (3 years (1-8)/5 years (2-10)), lower swollen joint count (2 (0-5)/3 (1-6)), higher visual-analogue-scale (VAS) patient global (72 mm (54-87)/68 mm (50-80)), VAS fatigue (72 mm (51-86)/63 mm (40-77)) and Health Assessment Questionnaire (HAQ) score (1.1 (0.7 to 1.5)/1.0 (0.5 to 1.5)) than never smokers (all p<0.05). Current smokers had shorter treatment adherence than never smokers (1.56 years (0.97 to 2.15)/2.43 years (1.88 to 2.97), (median (95% CI)), log rank p=0.02) and poorer 6 months' EULAR-good-response rates (23%/34%), ACR20 (24%/33%) and ACR50 response rates (17%/24%) (all p<0.05), most pronounced in men. In current smokers, the treatment adherence was poorer for infliximab (HR) 1.62, 95% CI 1.06 to 2.48) and etanercept (HR 1.74, 1.14 to 2.66) compared to never smokers, but not for adalimumab (HR 0.80, 0.52 to 1.23). CONCLUSION: In PsA, smokers had worse baseline patient-reported outcomes, shorter treatment adherence and poorer response to TNFi's compared to non-smokers. This was most pronounced in men and in patients treated with infliximab or etanercept.

RESUMEN

Tocilizumab (TCZ), a monoclonal antibody targeting the human interleukin-6-receptor (IL-6R), is indicated for the treatment of rheumatoid arthritis (RA). We examined whether three IL6R single-nucleotide polymorphisms rs12083537, rs2228145 (formerly rs8192284), and rs4329505 with previously reported functional effects were associated with clinical response to TCZ in a retrospective study cohort consisting of 79 RA patients. Three months after initiation of TCZ therapy, changes in swollen joint count (SJC) and, subordinately, tender joint count (TJC), serum-CRP, DAS28-CRP, and EULAR-response were tested for association with the IL6R-haplotype or genotype. The major allele (A) of rs12083537 and the minor allele (C) of rs4329505 were associated with a poor SJC response (P=0.02 and 0.02, respectively). Moreover, the AAC-haplotype (for rs12083537, rs2228145, and rs4329505, respectively) was associated with a poor SJC response (P=0.00004) and, with borderline significance, EULAR-response (P=0.05). These data suggest that genetic variation in IL6R may aid in predicting TCZ therapy outcome in RA patients.

RESUMEN

OBJECTIVE: To describe the frequency of treatment switching and outcomes among patients with psoriatic arthritis (PsA) who switched tumor necrosis factor α inhibitor (TNFi) agents in routine care. METHODS: We conducted an observational cohort study based on the Danish nationwide DANBIO registry. Treatment outcomes were evaluated using the American College of Rheumatology criteria for 20% improvement (ACR20)/ACR50/ACR70, European League Against Rheumatism (EULAR) response criteria for good response, and the 28-joint count Disease Activity Score (DAS28) (remission). Kaplan-Meier and regression analyses were used for drug survival analyses and to identify predictors of outcome after treatment switching. RESULTS: Of 1,422 patients starting TNFi agents, 548 patients (39%) switched to a second biologic drug during up to 10 years of followup. Median followup was 2.3 years (interquartile range [IQR] 1.0-4.3 years). Switchers were more frequently women (56% versus 45%), had a shorter disease duration (3 versus 4 years), a higher median Health Assessment Questionnaire (HAQ) score (1.1 [IQR 0.6-1.6] versus 0.9 [IQR 0.5-1.4]), DAS28 (4.8 [4.0-5.7] versus 4.4 [3.6-5.2]), pain score on a visual analog scale (VAS) (65 mm [46-77] versus 62 mm [40-75]), and fatigue score on a VAS (69 mm [50-83] versus 64 mm [42-80] mm) (all P < 0.05 at start of first TNFi). During the first and second treatment, HAQ, DAS28, and VAS scores and C-reactive protein levels had decreased after 6 months (all P < 0.05), and median drug survival was 2.2 versus 1.3 years (P < 0.001). Lower fatigue score increased survival of the second TNFi. After switching, the proportions of patients achieving a sustained ACR20, ACR50, ACR70, EULAR good response, and DAS28 remission after 3-6 months were 22% (number needed to treat [NNT] 4.5), 13% (NNT 7.9), 5% (NNT 20), 19% (NNT 5.3), and 34% (NNT 2.9), respectively. Response rates were lower during the second treatment (all P < 0.01 versus first TNFi). At the 2-year visit, 47% of switchers had achieved an ACR20 response. No differences between drug-drug combinations were found. CONCLUSION: Thirty-nine percent of the patients with PsA switched TNFi agents. Response rates and drug survival were lower after switching; however, half of the switchers had an ACR20 response 2 years after starting the first TNFi.

RESUMEN

OBJECTIVES: To investigate the incidence of cancer in arthritis patients treated with or without TNFα inhibitors (TNF-I). METHODS: Arthritis patients from the DANBIO database were followed-up for cancer in the Danish Cancer Registry during 2000-2008. RESULTS: Hazard ratio for cancer overall was 1.02 (95% confidence interval (CI) 0.80-1.30) in 3347 TNF-I-treated RA patients compared to non-treated. Excess among TNF-I-treated was found for colon cancer (HR 3.52 (95%CI 1.11-11.15), whereas 6 and 0 ovarian cancer cases were observed in treated and non-treated patients, respectively. Compared to the general population, TNF-I-treated RA patients had increased risk for cancer overall, cancer in lymphatic-haematopoietic tissue and non-melanoma skin cancer, while non-RA patients had no increase in overall cancer risk. CONCLUSIONS: Our results suggest that TNF-I therapy in routine care is not associated with an overall excess of cancer in arthritis patients, but observed increased risks of colon and ovarian cancer need further investigation.

RESUMEN

OBJECTIVES: To compare radiographic progression during treatment with disease-modifying antirheumatic drugs (DMARD) and subsequent treatment with tumour necrosis factor α inhibitors (TNF-I) in rheumatoid arthritis (RA) patients in clinical practice. METHODS: Conventional radiographs (x-rays) of hands and wrists were obtained ∼2 years before start (prebaseline), at baseline and ∼2 years after start (follow-up) of TNF-I. Clinical data were obtained from the DANBIO registry and the patient files. x-Rays were scored blinded to chronology according to the Sharp/van der Heijde method. Annual radiographic progression rates during the DMARD (prebaseline to baseline x-ray) and TNF-I (baseline to follow-up x-ray) periods were calculated. RESULTS: 517 RA patients (76% women, 80% IgM rheumatoid factor positive, 65% anticyclic citrullinated peptide positive, 40% current smokers, age 54 years (range 21-86), median disease duration 5 years (range 0-57)) were included. Patients were treated with infliximab (61%), etanercept (15%) or adalimumab (24%). During the DMARD period 85% of patients received methotrexate, 51% sulphasalazine and 78% prednisolone. The median DMARD period was 733 days (IQR 484-1002) and the median TNF-I period was 562 days (IQR 405-766). The median radiographic progression rate decreased from 0.7 (IQR 0-2.9) total Sharp score units/year (dTSS) in the DMARD period to 0 (0-0.9) units/year in the TNF-I period (p<0.0001, Wilcoxon). Corresponding mean dTSS values were 2.1 (SD 3.7) versus 0.7 (SD 2.3) units/year (p<0.0001, paired t test). 305 patients progressed (dTSS >0) in the DMARD period compared with 158 patients in the TNF-I period (p<0.0001, χ(2)). CONCLUSION: This nationwide observational study of RA patients documented significantly reduced radiographic progression during TNF-I treatment compared with the previous period of DMARD treatment.

RESUMEN

OBJECTIVE: To investigate frequencies and reasons for switching, treatment responses and drug survival in patients with ankylosing spondylitis (AS) switching tumour-necrosis-factor-α inhibitor (TNFi) treatment in routine clinical care. METHODS: AS patients were identified in the Danish nationwide DANBIO registry. Disease activity, treatment responses (50% or 20 mm reduction in Bath AS Disease Activity Index (BASDAI)), duration and rates of drug survival and predictors thereof were studied in patients receiving ≥2 different biological drugs. RESULTS: Of 1436 AS patients starting TNFi treatment, 432 patients (30%) switched to a second and 137 (10%) to a third biological drug. Compared with non-switchers, switchers were more frequently women (33%/22%), had shorter disease duration (3 years/5 years) and higher BASDAI (62(52-76) mm/56(43-69) mm (median(interquartile-range))), Bath AS Functional Index (BASFI) (54(39-71) mm/47(31-65) mm) and visual-analogue-scale (VAS) global, pain and fatigue scores when they started the first TNFi (all p<0.01). Main reason for switching was lack of response (56%). During the first, second and third treatment BAS- and VAS scores had decreased after 6 months' treatment (all p<0.05). Median drug survivals were 3.1, 1.6 and 1.8 years respectively (p<0.001). After 2 years of treatment 52% of switchers and 63% of non-switchers had achieved response (number needed to treat 1.9 and 1.6, respectively, p=0.01). Drug survivals were similar regardless of the reason for switching. Male gender and low BASFI predicted drug survival of the second TNFi. CONCLUSIONS: Nearly one-third of AS patients in clinical practice switched biological treatment. Response rates and drug survivals were lower among switchers, however, half of switchers achieved treatment response.

RESUMEN

OBJECTIVE: To investigate the short-term and long-term efficacy of intra-articular betamethasone injections, and the impact of joint area, repeated injections, MRI pathology, anticyclic citrullinated peptide (CCP) and immunoglobulin M rheumatoid factor (IgM-RF) status in patients with early rheumatoid arthritis (RA). METHODS: During 2 years of follow-up in the CIMESTRA trial, 160 patients received intra-articular betamethasone in up to four swollen joints/visit in combination with disease-modifying antirheumatic drugs. Short-term efficacy was assessed by EULAR good response. Long-term efficacy by Kaplan-Meier plots of the joint injection survival (ie, the time between injection and renewed flare). Potential predictors of joint injection survival were tested. RESULTS: 1373 Unique joints (ankles, elbows, knees, metacarpophalangeal (MCP), metatarsophalangeal, proximal interphalangeal (PIP), shoulders, wrists) were injected during 2 years. 531 Joints received a second injection, and 262 a third. At baseline, the median numbers of injections (dose of betamethasone) was 4 (28 mg), declining to 0 (0 mg) at subsequent visits. At weeks 2, 4 and 6, 50.0%, 58.1% and 61.7% had achieved a EULAR good response. After 1 and 2 years, respectively, 62.3% (95% CI 58.1% to 66.9%) and 55.5% (51.1% to 60.3%) of the joints injected at baseline had not relapsed. All joint areas had good 2-year joint injection survival, longest for the PIP joints: 73.7% (79.4% to 95.3%). 2-Year joint injection survival was higher for first injections: 56.6% (53.7% to 59.8%) than for the second: 43.4% (38.4% to 49.0%) and the third: 31.3% (25.0% to 39.3%). Adverse events were mild and transient. A high MRI synovitis score of MCP joints and anti-CCP-negativity were associated with poorer joint injection survival, whereas IgM-RF and C-reactive protein were not. CONCLUSION: In early RA, intra-articular injections of betamethasone in small and large peripheral joints resulted in rapid, effective and longlasting inflammatory control. The cumulative dose of betamethasone was low, and the injections were well tolerated.

RESUMEN

OBJECTIVES: To compare the effectiveness and safety of rituximab alone or in combination with either methotrexate or leflunomide. METHODS: 10 European registries submitted anonymised datasets with baseline, 3, 6, 9 and 12-month clinical data from patients who started rituximab. RESULTS: 1195 patients were treated with rituximab plus methotrexate, 177 with rituximab plus leflunomide and 505 with rituximab alone. Significantly more patients achieved a European League Against Rheumatism good response at 6 months when treated with rituximab plus leflunomide (29.1%) compared with rituximab plus methotrexate (21.1%) and rituximab alone (19.3%; p=0.02 and p=0.01, respectively). Similar results were observed at 12 months. Adverse events occurred in 10.2%, 13.2% and 13.9% of patients on rituximab plus leflunomide, rituximab plus methotrexate and rituximab alone, respectively. CONCLUSIONS: Leflunomide is an effective and safe alternative to methotrexate as concomitant treatment with rituximab. Slightly better results were obtained by the combination of rituximab and leflunomide than rituximab and methotrexate, raising the possibility of a synergistic effect of leflunomide and rituximab.

RESUMEN

OBJECTIVE: To investigate disease activity, treatment response, and drug survival, and predictors thereof, among Danish patients with psoriatic arthritis (PsA) receiving their first treatment series with a tumor necrosis factor α (TNFα) inhibitor. METHODS: Patients with PsA were identified from a prospective nationwide rheumatologic database, the Danish biologics registry DANBIO, using data registered from 2000-2009. Information was obtained on the patients' clinical response to anti-TNFα treatment (defined as achievement of the American College of Rheumatology 20% [ACR20], ACR50, and ACR70 improvement criteria or a European League Against Rheumatism [EULAR] good response at least once during the first 6 months of treatment) and duration and rate of drug adherence (referred to as drug survival), as well as predictors thereof. RESULTS: Of 764 patients with PsA, 320 received adalimumab, 260 infliximab, and 184 etanercept. Median drug survival was 2.9 years, and 1-year and 2-year drug survival rates were 70% and 57%, respectively. Clinical parameters that showed improvement over 6 months were the C-reactive protein (CRP) level, Health Assessment Questionnaire score, and 28-joint Disease Activity Score. Male sex, CRP level >10 mg/liter, concomitant methotrexate use, and low patient health visual analog scale score at baseline were associated with longer drug survival. Improvement was achieved by 59%, 45%, 24%, and 54% of patients according to the ACR20, ACR50, ACR70 response criteria and EULAR good response, respectively. A CRP level >10 mg/liter was predictive of the improvement responses (odds ratio [OR] 2.6 for ACR20, OR 3.0 for ACR50, OR 3.6 for ACR70, and OR 2.2 for EULAR good response). CONCLUSION: In these patients with PsA treated with their first TNFα inhibitor in clinical practice, high drug adherence and responder rates were observed. Moreover, increased levels of CRP at baseline were associated with both good treatment responses and continued treatment, which may be of clinical value in selecting the patients most likely to benefit from treatment with TNFα inhibitors.

RESUMEN

The IGF-IR density on CD4+T-lymphocytes was studied using flow cytometry in 40 early steroid- and DMARD-naïve rheumatoid arthritis (RA) patients before and after 52 weeks of treatment with methotrexate+placebo or methotrexate+cyclosporine A and in 15 controls. RA patients had increased IGF-IR density on CD4+T-lymphocytes at week 0 and week 52, irrespective of treatment. IGF-IR-positive CD4+T-lymphocytes fraction decreased during treatment, but neither at week 0 nor at week 52 did it differ from healthy controls. No correlations were found to disease activity parameters.

RESUMEN

OBJECTIVES: To describe drug survival, disease activity and clinical response in patients with rheumatoid arthritis (RA) treated with abatacept or tocilizumab in routine care, based on prospectively registered observational data from the nationwide Danish DANBIO registry. METHODS: 150 Patients with RA treated with abatacept and 178 treated with tocilizumab were identified. Drug survival was investigated. Response data were available in 104 and 97 patients, respectively. Changes in 28-joint Disease Activity Score (DAS28) based on C-reactive protein (CRP) and European League Against Rheumatism (EULAR) response after 24 and 48 weeks were investigated. No direct comparison of drugs was made. RESULTS: Median (IQR) disease duration was 8.5 (3-14)/9 (3-12) years (abatacept/tocilizumab). 95%/93% of patients had previously received one or more tumour necrosis factor inhibitor (TNFi). After 48 weeks, 54%/64% of patients (abatacept/tocilizumab) maintained treatment. Among patients with available response data, DAS28 was 5.3 (4.7-6.1), 3.4 (2.7-4.9) and 3.3 (2.5-4.3) at baseline, weeks 24 and 48, respectively, in the abatacept group and 5.4 (4.7-6.2), 2.9 (2.3-4.0) and 2.5 (1.9-4.5) in the tocilizumab group. At weeks 24 and 48, the remission rates for abatacept/tocilizumab were 19%/39% and 26%/58%, respectively. EULAR good-or-moderate response rates were 70%/88% and 77%/84%, respectively. The decline in DAS28 variables over time appeared similar between drugs, except for CRP, which seemed to decline more rapidly among tocilizumab-treated patients. CONCLUSIONS: In patients with RA (≥90% TNFi failures), a good-or-moderate EULAR response was achieved in ≥70% of patients treated with abatacept or tocilizumab for 24 weeks in routine care. Apparent declines in DAS28 variables over time were similar between drugs, except for the more rapid CRP decline among tocilizumab-treated patients, directly caused by interleukin 6 inhibition.

RESUMEN

OBJECTIVE: To assess the 6-month effectiveness of the first rituximab (RTX) course in rheumatoid arthritis (RA) and to identify possible predictors of response. METHOD: 10 European registries submitted anonymised datasets (baseline, 3- and 6-month follow-up) from patients with RA who had started RTX, and datasets were pooled and analysed. Heterogeneity between countries was analysed by analysis of variance. Predictors of response were identified by logistic regression. RESULTS: 2019 patients were included (mean age/disease duration 53.8/12.1 years, 80.3% female, 85.6% rheumatoid factor (RF) positive and 76.8% (456/594 patients) anti-cyclic citrullinated peptide antibodies (anti-CCP) positive). For these patients an average of 2.7 disease-modifying antirheumatic drugs (DMARDs) (range 0-10) had failed, and RTX was given as the first biological agent in 36.6% of patients. There was significant heterogeneity between countries for several baseline characteristics, including the number of previous biological agents. Disease Activity Score based on 28 joint counts (DAS28) decreased from 5.8±1.4 at baseline to 4.2±1.4 at 6 months (p<0.0001) and 22.2%/42.5% achieved European League Against Rheumatism (EULAR) good/moderate response. Larger 6-month improvement in DAS28 was observed in RF-positive and anti-CCP-positive versus seronegative patients. The following predictors of EULAR good response at 6 months were identified in a multivariate analysis: anti-CCP positivity (OR=2.86, p=0.003), number of previous DMARDs (OR=0.84, p=0.06), ≤1 previous biological agents (OR=1.89, p=0.04), baseline DAS28 level (OR=0.74, p=0.003). CONCLUSION: In this large observational cohort of patients with RA treated with RTX, seropositive patients achieved significantly greater reductions in DAS28 at 6 months than seronegative patients. Effectiveness was best when RTX was used as the first biological agent or after failure of no more than one anti-tumour necrosis factor agent.

RESUMEN

OBJECTIVES: The introduction of biological therapies for the treatment of rheumatic diseases has drawn attention to the limitations of traditional means of assessing drug safety. Consequently, a series of European academic biologics registers dedicated to this task have been established. Increasing reliance upon safety data generated from observational drug registers makes it important to convert the lessons learned from such registers into recommendations for rheumatologists embarking upon the establishment of future registers, or analysing and reporting from new and existing registers. METHODS: The Task Force encompassed 11 scientists from European Rheumatology drug registers. Through an informal inventory of critical elements in the establishment of existing rheumatoid arthritis drug registers, of analytical strategies used and of limitations of their results, several 'points to consider'--beyond established generic guidelines for observational registers/studies but with particular relevance to biologics registers on safety in rheumatology--were assembled. For each 'point to consider', contextual and methodological background and examples were compiled. RESULTS: A set of seven points to consider was assembled for the establishment of new drug registers with a focus on purpose, population to be targeted, data collection, handling and storage as well as ethical and legal considerations. For analysis and reporting, nine points to consider were assembled (setting, participant, variable, statistical method, descriptive data, outcome data, main results, other analyses and limitations). CONCLUSIONS: Thoughtful design and planning before the establishment of biologics registers will increase their sustainability, versatility and raw data quality. Harmonisation of analyses and reporting from such registers will improve interpretation of drug safety studies.

RESUMEN

OBJECTIVE: At 5 years' follow-up of early (<6 months) rheumatoid arthritis patients to (1) investigate whether initial combination therapy with methotrexate (MTX) and ciclosporin (CSA) (n=80) is superior to initial monotherapy with MTX (n=80) with respect to prevention of radiographic progression, (2) investigate whether the favourable clinical and radiographic response reported at 2 years in the CIMESTRA trial can be maintained and (3) identify predictors of radiographic outcome. METHODS: 139 patients completed 5 years' follow-up with maintained double-blinding and a strict synovitis suppressive treatment strategy with intra-articular betamethasone injections (intra-articular glucocorticosteroid (GC)) and escalation of disease-modifying anti-rheumatic drug treatment. Disease activity, total Sharp-van der Heijde Score (TSS) of hands, wrists and forefeet were assessed at baseline and after 3, 4 and 5 years. MRI of the wrist and anti-cyclic citrullinated peptide (anti-CCP) were assessed at baseline. RESULTS: At 5 years, TSS progression rate was <1 unit/year and 47% had not progressed radiographically since baseline. 78% were in Disease Activity Score remission, 56% in American College of Rheumatology remission and 17% withdrawn from treatment due to remission. There were no differences between initial treatment groups. MRI-bone marrow oedema, TSS and anti-CCP predicted radiographic progression at 5 years. CONCLUSION: Early and strict synovitis suppressive treatment with MTX and intra-articular GC lead to high remission rates and halting of erosive progression at 5 years. No additional effect of initial combination therapy with CSA was found. The results parallel those reported for tumour necrosis factor α antagonists. Baseline MRI-bone oedema, TSS and anti-CCP predicted radiographic progression.

RESUMEN

OBJECTIVE: Little is known about the prognosis of infections in patients with ankylosing spondylitis (AS) compared with patients without AS. The purpose of this study was to examine whether AS is associated with poorer outcomes in patients who are hospitalised with pneumonia. METHODS: In a population-based cohort study including patients with hospitalised pneumonia with and without AS, we compared 90-day rates of mortality, all-cause readmission (90 days post-discharge) and pulmonary complications including pulmonary embolism, empyema and pulmonary abscess. We used Cox regression analyses to compute crude and adjusted HRs while adjusting for sex, age and level of comorbidity. RESULTS: A total of 387 796 patients (median age 71 years) were hospitalised for pneumonia in Denmark between 1997 and 2017. Among these, 842 (0.2%) had AS (median age 65 years). The 90-day mortality was 12.5% in patients with AS and 15.5% in patients with non-AS pneumonia, with crude and adjusted 90-day HRs of 0.79 (95% CI 0.66 to 0.96) and 0.95 (95% CI 0.79 to 1.16), respectively. The 90-day post-discharge readmission rate was 27.3% in patients with AS and 25.4% in patients without AS, with a corresponding adjusted readmission HR of 1.12 (95% CI 0.98 to 1.27). Relative risk of pulmonary complications among patients with AS compared with patients without AS decreased over the study period, with adjusted HRs of 1.63 (95% CI 0.82 to 3.27) in 1997-2006 falling to 0.62 (95% CI 0.31 to 1.23) in 2007-2017. CONCLUSIONS: AS is not associated with increased mortality following hospitalisation for pneumonia. Furthermore, no increased risk of readmission or pulmonary complications in patients with AS was detected in recent study years.

RESUMEN

OBJECTIVE: Patients with rheumatoid arthritis (RA) experience an increased risk of infections, but the prognosis of infections is unclear. We examined if patients with RA have worse outcomes from pneumonia than non-RA individuals. METHODS: In a population-based cohort study, we computed 90-day mortality rates and crude and adjusted HRs comparing pneumonia patients with and without RA. Among patients with RA, we evaluated prognostic effects of RA medications including prednisolone and disease activity as assessed by C reactive protein (CRP) or platelet levels measured 30-180 days before admission to avoid any influence from the subsequent infection. RESULTS: Among 52 577 patients hospitalised for the first time with pneumonia, 1220 (2.3%) had RA. The 90-day mortality was 19.9% for patients with RA and 18.9% for non-RA patients (adjusted 90-day HR of 1.05 (95% CI 0.92 to 1.19)). Compared with CRP levels <8 mg/L, CRP levels ≥20 mg/L predicted increased mortality in patients with RA with adjusted 90-day HRs of 4.98 (95% CI 2.19 to 11.36). Compared with methotrexate monotherapy, both prednisolone (HR 1.43 (95% CI 0.91 to 2.22)) and no RA therapy (HR 1.35 (95% CI 0.85 to 2.14)) tended to increase 90-day mortality. Compared with patients who used prednisolone and had low CRP levels, high CRP predicted increased mortality both in patients who used prednisolone (HR 3.09, 95% CI 1.25 to 7.65) and those who did not (HR 2.35, 95% CI 0.94 to 5.87). CONCLUSIONS: Overall, RA does not increase mortality following hospitalisation for pneumonia. However, high RA disease activity prior to admission predicts increased pneumonia mortality in patients regardless of prednisolone use.

RESUMEN

OBJECTIVE: To test the effect of patient-reported outcome (PRO)-based tele-health followup for tight control of disease activity in patients with rheumatoid arthritis (RA), and the differences between tele-health followup performed by rheumatologists or rheumatology nurses. METHODS: A total of 294 patients were randomized (1:1:1) to either PRO-based tele-health followup carried out by a nurse (PRO-TN) or a rheumatologist (PRO-TR), or conventional outpatient followup by physicians. The primary outcome was a change in the Disease Activity Score in 28 joints (DAS28) after week 52. Secondary outcomes were physical function, quality of life, and self-efficacy. The noninferiority margin was a DAS28 score change of 0.6. Mean differences were estimated following per protocol, intent-to-treat (ITT), and multivariate imputation analysis. RESULTS: Overall, patients had low disease activity at baseline and end followup. Demographics and baseline characteristics were similar between groups. Noninferiority was established for the DAS28. In the ITT analysis, mean differences in the DAS28 score between PRO-TR versus control were -0.10 (90% confidence interval [90% CI] -0.30, 0.13) and -0.19 (90% CI -0.41, 0.02) between PRO-TN versus control. When including 1 yearly visit to the outpatient clinic, patients in PRO-TN had mean ± SD 1.72 ± 1.03 visits/year, PRO-TR had 1.75 ± 1.03 visits/year, and controls had 4.15 ± 1.0 visits/year. This included extra visits due to inflammatory flare. CONCLUSION: Among RA patients with low disease activity or remission, a PRO-based tele-health followup for tight control of disease activity in RA can achieve similar disease control as conventional outpatient followup. The degree of disease control did not differ between patients seen by rheumatologists or rheumatology nurses.

RESUMEN

BACKGROUND: The approved dose of rituximab (RTX) in rheumatoid arthritis is 1000 mg × 2, but some data have suggested similar clinical efficacy with 500 mg × 2. The purpose of this study was to compare the effectiveness of the regular and low doses given as first treatment course. METHODS: Twelve European registries participating in the CERERRA collaboration (The European Collaborative Registries for the Evaluation of Rituximab in Rheumatoid Arthritis) submitted anonymized datasets with demographic, efficacy and treatment data for patients who had started RTX. Treatment effectiveness was assessed by DAS28 reductions and EULAR responses after 6 months. RESULTS: Data on RTX dose were available for 2,873 patients, of whom 2,625 (91.4 %) and 248 (8.6 %) received 1000 mg × 2 and 500 mg × 2, respectively. Patients treated with 500 mg × 2 were significantly older, had longer disease duration, higher number of prior DMARDs, but lower number of prior biologics and lower baseline DAS28 than those treated with 1000 mg × 2. Fewer patients in the low-dose group received concomitant DMARDs but more frequently received concomitant corticosteroids. Both doses led to significant clinical improvements at 6 months. DAS28 reductions at 6 months were comparable in the 2 dose regimens [mean DeltaDAS28 ± SD -2.0 ± 1.3 (high dose) vs. -1.7 ± 1.4 (low dose), p = 0.23 adjusted for baseline differences]. Similar percentages of patients achieved EULAR good response in the two dose groups, 18.4 % vs. 17.3 %, respectively (p = 0.36). CONCLUSIONS: In this large observational cohort initial treatment with RTX at 500 mg × 2 and 1000 mg × 2 led to comparable clinical outcomes at 6 months.

RESUMEN

BACKGROUND: Rheumatoid arthritis is characterised by progressive joint destruction and loss of periarticular bone mass. Hand bone loss (HBL) has therefore been proposed as an outcome measure for treatment efficacy. A definition of increased HBL adjusted for age- and sex-related bone loss is lacking. In this study, we aimed to: 1) establish reference values for normal hand bone mass (bone mineral density measured by digital x-ray radiogrammetry (DXR-BMD)); and 2) examine whether HBL is normalised in rheumatoid arthritis patients during treatment with tumour necrosis factor alpha inhibitors (TNFI). METHODS: DXR-BMD was measured from hand x-rays in a reference cohort (1485 men/2541 women) without arthritis randomly selected from an urban Danish population. Sex- and age-related HBL/year was estimated. DXR-BMD was measured in rheumatoid arthritis patients (n = 350: at start of TNFI, and ~2 years after TNFI start), of which 135 patients had three x-rays (~2 years prior to TNFI, at start of TNFI, and ~2 years after TNFI start). Individual HBL/year prior to and during TNFI was calculated and compared to reference values. RESULTS: Estimated HBL/year varied strongly with age and sex. Compared to the reference values, 75 % of 135 patients had increased HBL prior to TNFI treatment and 59 % had increased HBL during TNFI treatment (p = 0.17, Chi-squared). In 38 % (38/101) of patients with increased HBL, HBL was normalised during TNFI treatment, whereas 47 % (16/34) of patients with normal HBL prior to TNFI had increased HBL during TNFI treatment. In the 350 patients, increased HBL during TNFI was associated with time-averaged 28-joint disease activity score (odds ratio 1.69 (95 % Confidence Interval 1.34-2.15)/unit increase, p < 0.001), and patients in time-averaged remission had lower HBL than patients without remission (0.0032 vs. 0.0058 g/cm(2)/year; p < 0.001, Mann-Whitney). CONCLUSIONS: We established age- and sex-specific reference values for DXR-BMD in a large cohort without arthritis. HBL was increased in the majority of rheumatoid arthritis patients initiating TNFI in clinical practice, and only normalised in a minority during TNFI.
