RESUMO
OBJECTIVE: To describe the trends in remission rates among RA patients in the OPAL dataset, spanning from 2009 to 2022, and provide insights into the effectiveness of evolving RA management approaches in real-world clinical settings. METHODS: Patients with a physician diagnosis of RA and at least 3 visits between 1 January 2009 and December 2022 were identified in the OPAL dataset, an aggregated collection of data extracted from the electronic medical records of patients managed by 117 Australian rheumatologists. Demographics, disease history, prescribed medications and proportions of patients in Disease Activity Score 28-joint count C-reactive protein (DAS28CRP)) categories (remission, low disease activity (LDA), moderate disease activity (MDA) and high disease activity (HDA)) were described. RESULTS: A large population (n = 48,388) of eligible patients with RA were identified in the OPAL dataset. A consistent and substantial improvement in DAS28CRP remission rates were found in (i) all patients, (ii) patients managed on conventional synthetic disease-modifying antirheumatic drugs (csDMARD) and (iii) patients treated with biological or targeted synthetic (b/ts)DMARD therapy, increasing from approximately 50% in 2009 to over 70% by 2022. The increase in DAS28CRP remission was accompanied by reduced proportions of patients in MDA and HDA states. CONCLUSION: This study highlights a consistent improvement in disease activity and rising remission rates among Australian RA patients within the OPAL dataset, offering the potential for enhanced patient outcomes and reduced disease burden.

BACKGROUND AND AIMS: This study aimed to assess the comparative effectiveness of the etanercept (ETN) originator (Enbrel) and ETN biosimilar SB4 (Brenzys) as first-line treatment in patients with rheumatoid arthritis (RA), while also exploring the potential cost-savings associated with this approach in Australia. METHODS: Clinical data were obtained from the Optimising Patient outcomes in rheumatoLogy Australian real-world data set. Adult patients with RA who had initiated treatment with the ETN originator or biosimilar as their first-recorded biologic or targeted synthetic disease-modifying antirheumatic drug between 1 April 2017 and 31 December 2020 were included. Treatment persistence was analysed using survival analysis. Cost-savings were estimated based on data reported by the Australian National Prescribing Service MedicineWise. RESULTS: Propensity score matching followed by inverse probability of treatment weighting selected patients taking originator (n = 209) or biosimilar (n = 141) with similar baseline characteristics and eliminated small differences in baseline disease activity. The median time for 50% of the patients to stop treatment was 19.4 months (95% confidence interval [CI], 14.7-36.4 months) for the originator and 22.4 months (95% CI, 15.0-33.1 months) for the biosimilar (P = 0.95). As a result of pricing policies established by the Australian Government, introduction of the ETN biosimilar would have resulted in a cost-savings of over AU$9.5 million for 1 year of treatment for the patients reported in this study. CONCLUSION: Treatment persistence using either ETN originator or biosimilar was similar. The cost of all brands of ETN markedly reduced upon listing of the ETN biosimilar, resulting in significant savings for the Australian Government.
RESUMO
Importance: There is a need for observational studies to supplement evidence from clinical trials, and the target trial emulation (TTE) framework can help avoid biases that can be introduced when treatments are compared crudely using observational data by applying design principles for randomized clinical trials. Adalimumab (ADA) and tofacitinib (TOF) were shown to be equivalent in patients with rheumatoid arthritis (RA) in a randomized clinical trial, but to our knowledge, these drugs have not been compared head-to-head using routinely collected clinical data and the TTE framework. Objective: To emulate a randomized clinical trial comparing ADA vs TOF in patients with RA who were new users of a biologic or targeted synthetic disease-modifying antirheumatic drug (b/tsDMARD). Design, Setting, and Participants: This comparative effectiveness study emulating a randomized clinical trial of ADA vs TOF included Australian adults aged 18 years or older with RA in the Optimising Patient Outcomes in Australian Rheumatology (OPAL) data set. Patients were included if they initiated ADA or TOF between October 1, 2015, and April 1, 2021; were new b/tsDMARD users; and had at least 1 component of the disease activity score in 28 joints using C-reactive protein (DAS28-CRP) recorded at baseline or during follow-up. Intervention: Treatment with either ADA (40 mg every 14 days) or TOF (10 mg daily). Main Outcomes and Measures: The main outcome was the estimated average treatment effect, defined as the difference in mean DAS28-CRP among patients receiving TOF compared with those receiving ADA at 3 and 9 months after initiating treatment. Missing DAS28-CRP data were multiply imputed. Stable balancing weights were used to account for nonrandomized treatment assignment. Results: A total of 842 patients were identified, including 569 treated with ADA (387 [68.0%] female; median age, 56 years [IQR, 47-66 years]) and 273 treated with TOF (201 [73.6%] female; median age, 59 years [IQR, 51-68 years]). After applying stable balancing weights, mean DAS28-CRP in the ADA group was 5.3 (95% CI, 5.2-5.4) at baseline, 2.6 (95% CI, 2.5-2.7) at 3 months, and 2.3 (95% CI, 2.2-2.4) at 9 months; in the TOF group, it was 5.3 (95% CI, 5.2-5.4) at baseline, 2.4 (95% CI, 2.2-2.5) at 3 months, and 2.3 (95% CI, 2.1-2.4) at 9 months. The estimated average treatment effect was -0.2 (95% CI, -0.4 to -0.03; P = .02) at 3 months and -0.03 (95% CI, -0.2 to 0.1; P = .60) at 9 months. Conclusions and Relevance: In this study, there was a modest but statistically significant reduction in DAS28-CRP at 3 months for patients receiving TOF compared with those receiving ADA and no difference between treatment groups at 9 months. Three months of treatment with either drug led to clinically relevant average reductions in mean DAS28-CRP, consistent with remission.

OBJECTIVES: To evaluate retention, efficacy, and safety of subcutaneous (SC) abatacept over 2 years in patients with moderate-to-severe RA in the Abatacept SubCutaneOus in Routine clinical practicE (ASCORE) study. METHODS: Patients with RA who initiated SC abatacept 125 mg once weekly were enrolled in the international, observational, prospective multicentre ASCORE study into biologic-naïve or ≥ 1 prior biologic failure cohorts. PRIMARY ENDPOINT: abatacept retention rate at 2 years. Secondary endpoints: proportion of patients with good/moderate EULAR response rates based on DAS28 (ESR), low disease activity and/or remission according to DAS28 (ESR; ≤ 3.2/ < 2.6), SDAI (≤ 11/ ≤ 3.3), CDAI (≤ 10/ ≤ 2.8), and Boolean criteria. Retention rate by baseline serostatus was evaluated post hoc. RESULTS: Overall, 47% of patients remained on abatacept for 2 years, irrespective of treatment line. Higher abatacept retention rates were associated with lower prior biologic exposure. Generally, clinical outcomes showed that the proportion of patients with low disease activity/remission was higher in biologic-naïve patients (vs biologic-failure) and similar in those with 1 and ≥ 2 prior biologic failures. In patients on treatment at 2 years, good/moderate EULAR response rates of ~ 80% were consistently noted irrespective of prior biologic exposure. Across treatment lines, retention was greater in patients with seropositive (vs seronegative) RA. Patients with rheumatoid factor/anti-citrullinated protein antibody single-positive RA who were bio-naïve had higher retention than patients who were bio-experienced. CONCLUSIONS: In the ASCORE study, SC abatacept retention was 47% at 2 years with good clinical outcomes and was well-tolerated in the real-world setting. Abatacept retention and clinical response rates were higher in patients who received abatacept as an earlier- versus later-line biologic drug treatment and in those with seropositive RA. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02090556.

Objective: To develop a simple and secure technological solution to incorporate electronic patient-reported outcomes (ePROs) into routine clinical care. Methods: A novel ePRO questionnaire delivery system was developed by Software for Specialists (S4S) in partnership with OPAL Rheumatology Australia. Validated questionnaires were sent from the electronic medical record (EMR) (Audit4) of patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), lupus or giant cell arteritis (GCA) and delivered to the patient's email address or completed in the clinic waiting room using a smart device (in-practice). Completed questionnaires were encrypted and returned to the patient's Audit4. Deidentified clinical data was extracted and aggregated across all sites. Data collected between April 2016-Dec 2020 were analysed descriptively. Results: Between April 2016 to Dec 2020, 221,352 Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F), Patient Health Questionnaire-2 (PHQ-2) and/or HealthCare Resource Utilization (HCRU) questionnaires were sent from 39 of 42 contributing clinics (93%). 85% of questionnaires were delivered via email and 15% in-practice. Overall, 85% of patients completed at least one questionnaire, and of all questionnaires sent, 73% were completed. Females were more likely to engage with the questionnaires than males (87% vs. 81%), and older patients were slightly more likely to complete all questionnaires delivered. Conclusions: The novel Audit4 ePRO delivery system is an effective tool for incorporating PROs into routine clinical care. The data generated provides a unique opportunity to understand the full burden of disease for patients in the real-world setting and the impact of interventions.
RESUMO
INTRODUCTION: Sleep disturbance and fatigue are commonly reported in ankylosing spondylitis (AS) but specific prevalence and the relationship to disease control are unknown. METHOD: This retrospective non-interventional observational study of data from the OPAL dataset included patients with AS (ICD code M45, M45.0 or M08.1), aged 18 to 95 years and had completed ≥ 1 sleep questionnaire between 1 January 2019 and 30 September 2020. The prevalence of insomnia and obstructive sleep apnoea were assessed using the Insomnia Severity Index (ISI) and Multivariate Apnoea Prediction Index (MAPI), respectively. Propensity score (PS) matching based on sex, age and symptom duration increased comparability between patients administered tumour necrosis factor inhibitors (TNFi) and interleukin 17A inhibitors (IL-17Ai). RESULTS: Four hundred ninety-five patients were included. The mean ISI total score in the overall population was 8.6 ± 6.2. Self-reported moderate or severe clinical insomnia was present in 16% and 3.2% of patients, respectively. The mean MAPI score was 0.4 ± 0.3, self-reported apnoea was identified in 31.5% of patients and the mean FACIT-Fatigue score was 36.1 ± 10.7. In the PS matched population, the only treatment-related difference was the mean MAPI score (IL-17Ai 0.4 ± 0.3 and TNFi 0.3 ± 0.2, p = 0.046). Those with poor disease control (BASDAI ≥ 4) were more likely (odds ratio [OR] 7.29, 95% CI 2.37 to 22.46, p = 0.001) to have a greater severity of insomnia symptoms than those with good disease control. CONCLUSION: In this real-world AS cohort, poor disease control was associated with sleep disturbance. Little difference in sleep disturbance was observed between biologic TNFi and IL-17Ai treatment. Key Points ⢠Sleep disturbance and fatigue are common in patients with ankylosing spondylitis. ⢠In our real-world cohort, self-reported apnoea was reported in one-third of patients; and one in five patients reported moderate to severe insomnia. ⢠Those with poor disease control were more likely to experience greater sleep disturbance than those with good disease control.

OBJECTIVE: To describe the treatment response and persistence to biologic disease-modifying antirheumatic drug (bDMARD) therapy in patients with ankylosing spondylitis (AS) in a real-world Australian cohort. METHODS: This was a retrospective, noninterventional cohort study that extracted data for patients with AS from the Optimising Patient outcomes in Australian RheumatoLogy (OPAL) dataset for the period of August 2006 to September 2019. Patients were classified as either bDMARD initiators if they commenced a bDMARD during the sampling window, or bDMARD-naïve if they did not. Results were summarized descriptively. Treatment persistence was calculated using Kaplan-Meier methods. Differences in treatment persistence were explored using log-rank tests. RESULTS: There were 5048 patients with AS identified. Of these, 2597 patients initiated bDMARDs and 2451 remained bDMARD-naïve throughout the study window. Treatment with first-, second-, and third-line bDMARDs significantly reduced disease activity. Median persistence on first-line bDMARDs was 96 months (95% CI 85-109), declining to 19 months (95% CI 16-22) in second-line therapy, and 15 months (95% CI 11-18) in third-line therapy. Median persistence was longest for the golimumab (GOL) group in all lines of therapy and shortest for the etanercept (ETN) group. Differences in persistence rates according to the time period that bDMARDs were prescribed (pre- and post-2012) were also seen for ETN and adalimumab. CONCLUSION: In this cohort, all bDMARDs effectively reduced AS disease activity. Treatment persistence was sustained for up to 8 years for patients remaining on their first bDMARD, longer than on subsequent agents. Further research is needed to determine its influence on treatment recommendations.

OBJECTIVE: This study aimed to describe the real-world effectiveness and treatment persistence among patients with rheumatoid arthritis treated with monotherapy and combination therapy tofacitinib and biologic disease-modifying antirheumatic drugs (bDMARDs). METHODS: This was a post hoc analysis of a retrospective, non-interventional study that extracted data for patients treated with tofacitinib or bDMARDs from the Australian OPAL dataset between March 2015 and September 2018. Monotherapy tofacitinib and bDMARDs and combination therapy tofactinib and bDMARDs were propensity score matched and treatment effectiveness and persistence of the groups were evaluated. RESULTS: In the bDMARD and tofacitinib monotherapy and combination therapy matched populations there were 1300 bDMARD initiators (n = 564 monotherapy) and 650 tofacitinib initiators (n = 282 monotherapy). In the bDMARD and tofacitinib monotherapy matched groups, 62.9% and 66.7% were in DAS-28 CRP disease remission after 18 months of treatment, respectively. In the combination therapy bDMARD and tofacitinib groups, 50% and 58.9% were in DAS-28 CRP disease remission after 18 months, respectively. The median treatment persistence was similar between the monotherapy bDMARD and tofacitinib treatment groups (36.7 months (95% CI 27.4 to "not reached') and 34.2 months (95%CI 30.3 to "not reached") respectively) as well as the combination therapy bDMARD and tofacitinib groups (32.2 months (95% CI 25.7 to 34.4) and 32.7 months (95%CI 28.7 to "not reached", respectively). CONCLUSIONS: Patients receiving combination therapy with tofacitinib or bDMARDs had higher disease activity scores at index than patients receiving monotherapy. Monotherapy with tofacitinib or bDMARDs, and combination therapy with tofacitinib or bDMARDs demonstrated similar treatment effectiveness and persistence, respectively. Key Points ⢠This study provides real-world evidence regarding effectiveness, treatment persistence, and treatment patterns, among patients with rheumatoid arthritis (RA) treated with monotherapy or combination therapy tofacitinib. ⢠The study suggests that monotherapy and combination therapy tofacitinib is an effective intervention in RA with persistence and effectiveness comparable to bDMARDs.

PURPOSE: To determine the usability of the ergonomically designed certolizumab pegol pre-filled pen (CZP PFP) in Australian patients with active ankylosing spondylitis, active psoriatic arthritis or moderate-to-severe rheumatoid arthritis. PATIENTS AND METHODS: CZP-naive patients were recruited from six clinical centers in Australia between November 2018 and May 2019. Patients and healthcare professionals (HCPs) reviewed training materials and completed pre-injection surveys; patients then self-administered ≥1 injection with the CZP PFP during each of three visits. Patients and HCPs then completed post-injection surveys. Some survey questions were adapted from the self-injection assessment questionnaire (SIAQv2.0). RESULTS: Seventy patients participated (65 completed 3 visits); 33 were biologic-experienced. All patients agreed that training materials were informative; 94% found them easy to understand. Pre-injection, 89% of patients reported little or no anxiety about having injections; 67% (79% in biologic-experienced) were very confident about self-injecting the correct dose with the PFP. Ninety percent of patients were satisfied/very satisfied with their first experience with the CZP PFP; those with pre-injection anxiety reported lower satisfaction (43% vs 79% "very satisfied"). Confidence and satisfaction increased as visits progressed (for Visit 3 vs Visit 2: 69% vs 56% "very convenient"; 75% vs 67% "very confident"; 71% vs 57% "very satisfied"). All HCPs were confident in their patients' competence to self-inject and thought all patients had overall positive experiences. CONCLUSION: Australian patients with chronic rheumatic disease reported high levels of confidence and satisfaction following initial use of the CZP PFP. The availability of devices with patient-centered design innovations may help overcome barriers to self-injection for improved adherence/outcomes.
RESUMO
INTRODUCTION: The aim of this study was to describe the real-world evidence for effectiveness, treatment persistence, and treatment patterns among patients in the community with rheumatoid arthritis treated with the JAK inhibitor tofacitinib. METHODS: This was a retrospective, non-interventional cohort study that extracted data for new users of tofacitinib or biologic disease-modifying antirheumatic drugs (bDMARDs) from the Australian Optimizing Patient outcomes in Australian RheumatoLogy (OPAL) dataset between March 2015 and September 2018. Patients were propensity score matched at a 1:2 tofacitinib to bDMARD ratio based on age, sex, and selected baseline treatment combinations. Treatment effectiveness was evaluated using disease status measures. Treatment persistence was calculated and the percentage of patients receiving monotherapy or combination therapy at treatment initiation was evaluated. RESULTS: Data from 2810 patients were extracted and 1950 patients were included in the matched population (1300 bDMARD initiators and 650 tofacitinib initiators). Patients were predominantly aged 55 to 74 years (57.8%) and female (81.2%). After 18 months of treatment, 52.4% and 57.8% of patients had achieved disease activity score (DAS) remission in the bDMARD and tofacitinib groups, respectively. The median treatment persistence for tofacitinib was similar to that for bDMARDs: 34.2 months (95% CI 32.2 to not reached) and 33.8 months (95% CI 28.8 to 40.4), respectively. In the overall population, more patients were prescribed tofacitinib as monotherapy (43.4%) compared with bDMARD monotherapy (33.4%). CONCLUSIONS: Tofacitinib demonstrated treatment effectiveness and persistence similar to bDMARDs. Overall, there was a trend for more use of tofacitinib as monotherapy than bDMARDs. Key Points ⢠This study provides real-world evidence regarding effectiveness, treatment persistence, and treatment patterns, among patients with rheumatoid arthritis (RA) in the community being treated with tofacitinib. ⢠The study suggests that tofacitinib is an effective and enduring intervention in RA with tofacitinib persistence and effectiveness comparable to bDMARDs.

OBJECTIVE: To provide real-world evidence about the reasons why Australian rheumatologists cease biologic (b) and targeted synthetic (ts) disease-modifying antirheumatic drugs (DMARD) when treating patients with rheumatoid arthritis (RA), and to assess (1) the primary failure rate for first-line treatment, and (2) the persistence on second-line treatments in patients who stopped first-line tumor necrosis factor inhibitors (TNFi). METHODS: This is a multicenter retrospective, noninterventional study of patients with RA enrolled in the Australian Optimising Patient outcome in Australian RheumatoLogy (OPAL) dataset with a start date of b/tsDMARD between August 1, 2010, and June 30, 2017. Primary failure was defined as stopping treatment within 6 months of treatment initiation. RESULTS: Data from 7740 patients were analyzed; 6914 patients received first-line b/tsDMARD. First-line treatment was stopped in 3383 (49%) patients; 1263 (37%) were classified as primary failures. The most common reason was "lack of efficacy" (947/2656, 36%). Of the patients who stopped first-line TNFi, 43% (1111/2560) received second-line TNFi, which resulted in the shortest median time to stopping second-line treatment (11 months, 95% CI 9-12) compared with non-TNFi. The longest second-line median treatment duration after first-line TNFi was for patients receiving rituximab (39 months, 95% CI 27-74). CONCLUSION: A large proportion of patients who stopped first-line TNFi therapy received another TNFi despite evidence for longer treatment persistence on second-line b/tsDMARD with a different mode of action. Lack of efficacy was recorded as the most common reason for making a switch in first-line treatment of patients with RA.

OBJECTIVES: OPAL (Optimising Patient outcomes in Australian rheumatoLogy) Rheumatology is an independent not for profit Australian clinical research organisation which is the custodian of one of the largest datasets of patients with rheumatic diseases in the world, containing real-world clinical data from more than >175,000 unique patients collected over more than 900,000 clinical consultations. We describe the evolution and outcomes of the OPAL dataset, with particular reference to the use of big data derived from real-world clinical encounters to enhance clinical care and research. METHODS: De-identified data are regularly extracted and aggregated from the electronic medical records (EMR) of consenting patients treated by approximately 100 rheumatologists around Australia. The EMR shared by OPAL clinicians was specifically customised for rheumatology and collects comprehensive information on demographics, disease history, activity and severity, co-morbidities, pathology, and medication use. In addition, OPAL captures multifaceted outcomes data from the patient perspective through a novel electronic patient-reported outcome (ePRO) delivery system which allows for health-related quality of life measures to be matched with clinical indices. RESULTS: Since inception in 2009, OPAL has produced 35 publications and abstracts. OPAL also provides real-world data to determine drug utilisation, efficacy and safety, elucidate the natural history of disease, highlight areas of unmet need, guide medical affairs and commercial strategy, and to support regulatory and reimbursement submissions. CONCLUSIONS: The extensive, evolving and organic OPAL dataset reflects the complexities of clinical rheumatological practice. It provides unique opportunities to enhance clinical care and research.

BACKGROUND: The comparative effectiveness of biologic treatment regimens in a real world Australian population is unknown. AIM: To assess the effectiveness of biological disease-modifying anti-rheumatic drugs (bDMARD) as monotherapy or in combination with methotrexate and/or other conventional DMARD (cDMARD) for the treatment of rheumatoid arthritis (RA). METHODS: A retrospective, non-interventional study was conducted that investigated the use of bDMARD in adult patients with RA in routine clinical practice. Data were extracted from the Optimising Patient Outcomes in Australian Rheumatology - Quality Use of Medicines Initiative database. Real-world effectiveness was measured using the 28-joint disease activity score (DAS28) and clinical disease activity index (CDAI) by treatment group at baseline, weeks 12 and 24. RESULTS: A total of 2970 patients was included with a median (min-max) age of 60.0 (19.0-94.0) years and median (min-max) duration of RA before first bDMARD treatment of 6.0 (0.2-58.3) years. A total of 1177 patients received more than one bDMARD during the analysis period of 1 January 1997 to 15 August 2015. Patients had 4922 treatment 'episodes' (defined as a cycle of continuous individual bDMARD prescribing in a single patient). Patients received a mean (SD) of 1.7 (1.0) episodes of treatment with median (min-max) treatment duration of 0.7 (0-11.8) years; median treatment duration was higher with the first treatment episode. bDMARD were most commonly initiated in combination with methotrexate (73.9% of episodes) and least commonly as monotherapy (9.9% of episodes). Median (min-max) baseline DAS28 decreased from 5.3 (0-8.7) with the first bDMARD to 3.7 (0-8.8) with the second. Median baseline CDAI similarly decreased. CONCLUSIONS: Patients tended to persist longer on their first bDMARD treatment. bDMARD as monotherapy or in combination appear to be accepted treatment strategies in the real world.

AIM: Examine the efficacy of once-weekly subcutaneous tocilizumab (SC-TCZ) on joint damage at 24 weeks based on radiography of the hands and feet and magnetic resonance imaging (MRI) of the hand in subjects with moderate to severe rheumatoid arthritis (RA). METHODS: In this Australian open-label, multicentre, prospective, single-arm study, subjects received 162 mg SC-TCZ weekly. Primary endpoint was change in radiographic Genant-modified Total Sharp Score (TSS) between baseline and Week 24. Secondary endpoints included change from baseline to Week 24 in RA MRI scoring (RAMRIS) of erosions, synovitis, and osteitis and Cartilage Loss Score (CARLOS) in the dominant hand and disease activity score 28 (DAS28). RESULTS: 52 subjects were enrolled (80% female, mean (SD) age 57 (12) years). Radiography showed mild but not significant progression of joint damage (mean (SD) change in TSS 0.46 (1.29)). Synovitis reduced significantly on MRI; however, osteitis, erosion, and cartilage loss did not change significantly. DAS28 improved significantly by Week 24; 78% of subjects achieved DAS28 remission. SC-TCZ was generally well tolerated. CONCLUSION: Synovitis and DAS28 decreased significantly; however, no significant change in osteitis or joint damage was observed at Week 24. TRIAL REGISTRATION: This trial is registered with Clinicaltrials.gov registration number NCT01951170 (ML28703).
RESUMO
The aim was to describe the real-world treatment persistence of subcutaneous TNF inhibitors (TNFi) for patients with inflammatory rheumatic disease newly initiating treatment with biologic disease-modifying antirheumatic drugs (bDMARD). This was a retrospective cohort study that extracted data for new users of TNFi between 1 August 2010 and 31 August 2016 from the Australian Optimising Patient outcome in Australian RheumatoLogy (OPAL) registry. Patients were 1:1 propensity-score matched with golimumab based on their age, sex, year of index, C-reactive protein level, baseline treatment combination and disease. Treatment persistence was calculated. Data from 3749 patients were extracted (adalimumab n = 1518; certolizumab n = 298; etanercept n = 1068; golimumab n = 865). The mean (SD) ages of patients were 51.7 (14.2) years for adalimumab, 53.7 (14.0) years for certolizumab, 52.8 (14.3) years for etanercept and 52.3 (14.6) years for golimumab, with disease durations 7.7 (10.5), 8.8 (9.2), 8.1 (10.4) and 7.3 (9.7) years, respectively. Two thirds of the patients were women. There was no significant difference in treatment persistence by treatment in the overall population (adalimumab 33.6 [95% CI 28.6-40.7], certolizumab 24.8 [95% CI 21.3-42.1], etanercept 27.6 [95% CI 23.4-36.5], golimumab 30.3 [95% CI 23.26-36.5]; months, p = 0.545), or in the propensity score-matched population. No safety signals were detected.

AIM: To describe the treatment regimens, duration of therapy and reasons for disease-modifying antirheumatic drug (DMARD) cessation in a large psoriatic arthritis (PsA) cohort. METHODS: A retrospective non-interventional multi-centre study using Audit4 electronic medical records, with de-identified, routinely collected clinical data from rheumatology practices in the OPAL consortium (Optimising Patient outcomes in Australian rheumatoLogy) during November 2015. Baseline characteristics, type and duration of conventional and biologic DMARDs (cDMARD and bDMARD, respectively), disease activity (Disease Activity Score of 28 joints C-reactive protein [DAS28-CRP]), and reasons for treatment cessation were recorded. RESULTS: A total of 3422 rheumatologist-diagnosed PsA patients were included: 60% female, mean age 54 years and disease duration 10 years. Of patients with treatment recorded (n = 2948), 46% were on cDMARD monotherapy, 19% bDMARD monotherapy, 13% combination bDMARD and cDMARDs, 11% combination cDMARDs and 10% no DMARDs. Of those with DAS28-CRP results (n = 494), the highest mean DAS28-CRP was 3.32 on combination cDMARDs, and the lowest was 2.19 on bDMARD monotherapy. Median duration on cDMARD monotherapy was 33.5 months (n = 2232), on bDMARD monotherapy 110.1 months (n = 751), on combination bDMARD and cDMARDs 68.5 months (n = 559). The most common reasons for cessation of cDMARD monotherapy was adverse reactions (41%), for bDMARD monotherapy lack of efficacy (26%), and for combination bDMARD and cDMARDs treatment completed or no longer required (37%). CONCLUSION: Most PsA patients were prescribed DMARD therapies with a large proportion receiving cDMARDs. Patients on combination cDMARD therapies had the highest DAS28-CRP results. Adverse reactions were the most common reason for cessation of cDMARD monotherapy, whereas for bDMARD monotherapy it was lack of efficacy.

OBJECTIVES: To observe the choices of conventional disease modifying antirheumatic drugs (cDMARDs) and biologic DMARDs (bDMARDs) in the management of rheumatoid arthritis (RA) in Australian routine clinical practice, to assess treatment survival and determine the effect of cDMARDs/bDMARDs on disease activity. METHODS: Routinely collected, deidentified clinical data was sourced from 20 Australian rheumatology practices. RA patients aged ≥18 years, who had received cDMARDs/bDMARDs and a recorded subsequent visit, were included. A linear mixed model was used to determine the change over time and the percentage reduction in disease activity was summarized. RESULTS: 12,526 RA patients were included: 72% females, mean age 62 years. cDMARDs and bDMARDs were used in 92% and 30% of patients, respectively. The most commonly prescribed cDMARD was methotrexate (76% patients); median time to stopping treatment was 337 months [95% CI: 279-ND]. Etanercept was the most commonly prescribed bDMARD (12% patients); median time to stopping treatment was 79 months [95% CI: 57-93]. Of 5,341 patients with a first change in medication (cDMARD or bDMARD), 87% had therapy escalation and 13% deescalation. Reduction in DAS28-ESR, 6-month post-DMARDs initiation ranged from 3%, adalimumab, to 14%, leflunomide and tocilizumab. CONCLUSIONS: In this large Australian cohort of unselected community RA patients, the choices of cDMARDs/bDMARDs are aligned with current international guidelines.
RESUMO
AIM: To assess the association between baseline clinical prognostic factors and subsequent Disease Activity Score of 28 joints (DAS28) remission in early rheumatoid arthritis (RA). METHODS: Data were collected using point of care clinical software from participating rheumatology centres. Patients aged 18 years or over whose date of clinical onset of RA was within the previous 12-24 months, who had at least 6 months of follow-up data and a DAS28-ESR (erythrocyte sedimentation rate) score recorded between 12 and 24 months from first being seen for RA were included. Data collected included baseline demographics, mode of disease onset, pattern of joint involvement at onset, smoking status, DAS28, rheumatoid factor (RF), anti-citrullinated peptide antibodies (ACPA), time from symptom onset to presentation and disease activity at baseline. Univariate and multivariate logistic regression of DAS28-ESR remission between 12 and 24 months after first assessment were performed. RESULTS: Data from 1017 patients were analyzed: 70% female; mean age 60 years (SD: 14.7); 70% RF-positive, 58% ACPA-positive. The strongest age and sex adjusted baseline predictors of DAS28-ESR remission at 12-24 months were remission at baseline (odds ratio [OR]: 4.49, 95% CI: 2.17-9.29, P < 0.001), being male (OR: 2.42, 95% CI: 1.46-4.01, P < 0.001), abstaining from alcohol (P < 0.001) and being lower weight (OR: 0.98, 95% CI: 0.97-1.00, P = 0.015). There was no statistically significant association between joint onset patterns, mode of onset, RF, ACPA or smoking status. CONCLUSION: In this observational study, patients with early RA at risk of not achieving remission include those with high disease activity at baseline, women, those who drink alcohol and those with higher body weight.

Adult Onset Still's Disease (AOSD), an adult variant of systemic onset juvenile idiopathic arthritis, is a rare systemic inflammatory disorder of unknown aetiology. The rarity of this disease is associated with low index of suspicion and delayed diagnosis in patients suffering from it and in the presence of atypical features the diagnosis can be further challenging. This is a case report on a 24-year-old woman, who was a diagnostic dilemma for 2 years due to the nonspecific symptoms of recurrent fever, generalized maculopapular persistent pruritic and tender rash, and polyarthralgia. She was initially diagnosed as leukocytoclastic vasculitis on a skin biopsy and was managed by a dermatologist with various medications including NSAIDs, hydroxychloroquine, dapsone, colchicine, cyclosporine, and high doses of oral steroids with minimal response. Subsequently, she has had multiple admissions with similar symptoms with raised inflammatory markers and negative septic workup. On one occasion, her iron study revealed hyperferritinaemia which led to the suspicion of AOSD. Once the rheumatic fever and infectious, malignant, autoimmune, and lymphoproliferative disorders were excluded, she was diagnosed as probable AOSD and managed successfully with IL-1 (interleukin-1) receptor antagonist, Anakinra, with remarkable and lasting response both clinically and biochemically.
