Background: To investigate whether intensive treatment with methotrexate (MTX) according to a strict protocol and a computerised decision program is more beneficial compared to conventional treatment with MTX in early rheumatoid arthritis. Methods: In a two-year multicentre open label strategy trial, 299 patients with early rheumatoid arthritis were randomly assigned to the intensive strategy group or the conventional strategy group. Patients in both groups received MTX, the aim of treatment being remission. Patients in the intensive treatment group came to the outpatient clinic once every month; adjustment of the MTX dosage was tailored to the individual patient on the basis of predefined response criteria, using a computerised decision program. Patients of the conventional strategy group came to the outpatient clinic once every three months; they were treated according to common practice. Cyclosporine was added if patients had an inadequate response to maximal tolerated MTX doses. Results: Seventy six (50%) patients in the intensive strategy group achieved at least one period of remission during the two year trial, versus 55 patients (37%) in the conventional strategy group (p = 0.03). Areas under the curve for nearly all clinical variables were significantly lower—that is, there was a better clinical effect for the intensive treatment group compared with the conventional treatment group. Conclusion: The results of this study show that it is possible to substantially enhance the clinical efficacy early in the course of the disease by intensifying treatment with MTX, aiming for remission, tailored to the individual patient. Furthermore, participating rheumatologists indicated that the computerised decision program could be a helpful tool in their daily clinical practice.

Adverse effects of glucocorticoids have been abundantly reported. Published reports on low dose glucocorticoid treatment show that few of the commonly held beliefs about their incidence, prevalence, and impact are supported by clear scientific evidence. Safety data from recent randomised controlled clinical trials of low dose glucocorticoid treatment in RA suggest that adverse effects associated with this drug are modest, and often not statistically different from those of placebo.

Rovensky; A. Russell; Kenneth G. Saag; Björn Svensson; Rene Westhovens; H. Zeidler; J. W. J. Bijlsma

Objective: To develop evidence-based recommendations for the management of systemic glucocorticoid (GC) therapy in rheumatic diseases. Methods: The multidisciplinary guideline development group from 11 European countries, Canada and the USA consisted of 15 rheumatologists, 1 internist, 1 rheumatologist–epidemiologist, 1 health professional, 1 patient and 1 research fellow. The Delphi method was used to agree on 10 key propositions related to the safe use of GCs. A systematic literature search of PUBMED, EMBASE, CINAHL, and Cochrane Library was then used to identify the best available research evidence to support each of the 10 propositions. The strength of recommendation was given according to research evidence, clinical expertise and perceived patient preference. Results: The 10 propositions were generated through three Delphi rounds and included patient education, risk factors, adverse effects, concomitant therapy (ie, non-steroidal anti-inflammatory drugs, gastroprotection and cyclo-oxygenase-2 selective inhibitors, calcium and vitamin D, bisphosphonates) and special safety advice (ie, adrenal insufficiency, pregnancy, growth impairment). Conclusion: Ten key recommendations for the management of systemic GC-therapy were formulated using a combination of systematically retrieved research evidence and expert consensus. There are areas of importance that have little evidence (ie, dosing and tapering strategies, timing, risk factors and monitoring for adverse effects, perioperative GC-replacement) and need further research; therefore also a research agenda was composed.

In rheumatology and other medical specialties there is a discrepancy between the widespread use and the imprecise designation of glucocorticoid treatment regimens. Verbal descriptions of glucocorticoid treatment regimens used in various phases of diseases vary between countries and institutions. Given this background, a workshop under the auspices of the EULAR Standing Committee on International Clinical Studies including Therapeutic Trials was held to discuss this issue and to seek a consensus on nomenclature for glucocorticoid treatment. This report summarises the panels discussion and recognises that answers derived from consensus conferences are not definitive. Nevertheless, recommendations on glucocorticoid treatment are presented that (1) reflect current and best knowledge available and (2) take into account current clinical practice. A question-answer rationale presentation style has been chosen to convey the messages, to summarise the meeting in a readable format, and to avoid dogmatism.

Marije F. Bakker; J. W. G. Jacobs; Suzanne M. M. Verstappen; J. W. J. Bijlsma

Objective: To evaluate the available evidence on the efficacy and feasibility of the new concept of tight control in randomised trials in patients with rheumatoid arthritis (RA). Tight control is a treatment strategy tailored to the individual patient with RA, which aims to achieve a predefined level of low disease activity or remission within a certain period of time. Methods: The literature database PubMed was searched and yielded four trials: the FIN-RACo trial, the TICORA study, the BeSt study and the CAMERA study. Results: Tight control resulted in greater improvement and a higher percentage of patients meeting the preset aim of low disease activity or remission when compared to the control intervention. In the FIN-RACo trial, aimed at DAS28<2.6, 51% of patients in the tight control group achieved remission versus 16% in the contrast group (p<0.001). In the TICORA study, 65% of patients in the tight control group versus 16% of the contrast group achieved remission, based on DAS<1.6 (p<0.0001). In the CAMERA study, 50% of patients in the tight control group using a computer decision model achieved remission, versus 37% in the contrast group (p = 0.029). The BeSt study consisted of only tight control groups aimed at a DAS<1.6; remission was achieved in 38–46% of patients. This is higher than the range of remission in earlier trials of 13–36%. Conclusion: Tight control aiming for low disease activity or even better still, remission, seems a promising option in treating patients with RA in clinical trials and probably also in daily practice.

Objective To develop recommendations on monitoring for adverse events (AEs) of low-dose glucocorticoid (GC) therapy (≤7.5 mg prednisone or equivalent daily) in clinical trials and daily practice. Methods Literature was searched for articles containing information on incidence and monitoring of GC-related AEs using PubMed, EMBASE and Cochrane databases. Second, the authors searched for broad accepted guidelines on the monitoring of certain AEs (eg, WHO guidelines on screening for diabetes). Available data were summarised and discussed among experts (rheumatologists and patients) of the EULAR Task Force to decide which potential AEs should be monitored, how and at which interval. Results Data on monitoring proved to be scarce; most articles were focused on therapeutic effects of GCs, not on occurrence and monitoring of AEs. Most recommendations had to be based on consensus. Those for clinical trials aimed at getting insights into incidence, prevalence and clinical relevance of AEs to create a comprehensive and valid AE-profile of GC therapy. The set of AEs to monitor is therefore more extensive, and often consists of assessments at baseline and at end of trials. Recommendations for daily practice are meant to protect patients from real dangers, which can be prevented or treated. Standard care monitoring needs NOT be extended for patients on low-dose GC therapy, except for osteoporosis (follow national guidelines), and baseline assessments of ankle edema, fasting blood glucose and risk factors for glaucoma. Conclusion Given the incompleteness of literature data, consensus-based recommendations on monitoring for GC-related AEs were created, separately for daily practice and clinical trials.

To develop recommendations for the management of medium to high-dose (ie, >7.5 mg but ≤100 mg prednisone equivalent daily) systemic glucocorticoid (GC) therapy in rheumatic diseases. A multidisciplinary EULAR task force was formed, including rheumatic patients. After discussing the results of a general initial search on risks of GC therapy, each participant contributed 10 propositions on key clinical topics concerning the safe use of medium to high-dose GCs. The final recommendations were selected via a Delphi consensus approach. A systematic literature search of PubMed, EMBASE and Cochrane Library was used to identify evidence concerning each of the propositions. The strength of recommendation was given according to research evidence, clinical expertise and patient preference. The 10 propositions regarded patient education and informing general practitioners, preventive measures for osteoporosis, optimal GC starting dosages, risk-benefit ratio of GC treatment, GC sparing therapy, screening for comorbidity, and monitoring for adverse effects. In general, evidence supporting the recommendations proved to be surprisingly weak. One of the recommendations was rejected, because of conflicting literature data. Nine final recommendations for the management of medium to high-dose systemic GC therapy in rheumatic diseases were selected and evaluated with their strengths of recommendations. Robust evidence was often lacking; a research agenda was created.

OBJECTIVES To compare three therapeutic strategies using slow acting antirheumatic drugs (SAARDs) in early rheumatoid arthritis (RA), for their disease modifying properties, toxicity, and lag time until treatment effect. METHODS Patients with recent onset RA from six hospitals were randomly assigned to immediate initiation of one of three treatment strategies: (I) a “mild SAARD with a long lag time” (hydroxychloroquine, if necessary replaced by auranofin); (II) a “potent SAARD with a long lag time” (intramuscular gold, if necessary replaced byd-penicillamine); (III) a “potent SAARD with a short lag time” (methotrexate, if necessary replaced by sulfasalazine). Comparisons included two years of follow up. RESULTS All SAARD strategies reduced mean disease activity. A greater percentage of patients improved clinically with strategies II and III than with strategy I: percentages of patients improved on joint score with strategies II and III (79% and 82%, respectively), which was statistically different from strategy I (66%). The same was true for remission percentages: 31% and 24% v 16%, respectively). Longitudinal analysis showed significantly less disability with strategy III, and a lower erythrocyte sedimentation rate with strategy II than with strategy I. In addition, radiological damage after one and two years, was significantly lower in strategies II and III (at two years median scores were 11 and 10v 14 in strategy I, p<0.05). Toxicity was increased in strategy II compared with the other strategies. CONCLUSION Strategy III, comprising methotrexate or sulfasalazine, produced the best results weighing effectiveness and toxicity. Strategy I (hydroxychloroquine or auranofin) was slightly less effective, and strategy II (intramuscular gold or d-penicillamine) was associated with increased toxicity.

Holland; John R. Kirwan; J. Rovensky; Kenneth G. Saag; G. Severijns; S. Webber; Rene Westhovens; J. W. J. Bijlsma

Objective To explore perspectives among patients and rheumatologists on glucocorticoid (GC) therapy and European League Against Rheumatism (EULAR) recommendations on the management of systemic GC therapy in order to enhance implementation of the recommendations. Methods Rheumatologists (from eight countries) and patients (from five countries) acquainted with GCs participated in separate meetings, during which positive and negative aspects of GC therapy were discussed and possible adverse events (AEs) were ranked for importance; in addition participants were asked to evaluate the published EULAR recommendations. The reports from these meetings and themes related to implementation of the recommendations were discussed during an international forum of the experts who had formulated the recommendations and patient participants. Results In all, 140 patients (78% women; mean age 53 years; 61% patients with rheumatoid arthritis) and 110 rheumatologists (mean work experience 15 years) participated in the meetings. Osteoporosis, diabetes and cardiovascular diseases were ranked among the five most worrisome AEs by patients and rheumatologists. In both groups, there was agreement with most of the recommendations; the recommendations on GC information cards and GC use during pregnancy scored lowest. Ideas to improve implementation of the recommendations and a research agenda were generated. Conclusion The patient and rheumatologist views on GCs corresponded to a large extent, reflected by concerns in both groups about osteoporosis, diabetes and cardiovascular diseases. Specific problems with the EULAR recommendations were identified and addressed to improve their implementation. This exercise shows that patient and rheumatologist perspectives should be included early in the process of formulating recommendations.

Objectives To compare glucose tolerance and parameters of insulin sensitivity and β-cell function between chronic glucocorticoid (GC)-using and GC-naive patients with rheumatoid arthritis (RA). Methods Frequently sampled 75 g oral glucose tolerance tests were performed in 58 chronic GC-using and 82 GC-naive patients with RA with established disease, with no known type 2 diabetes mellitus (T2DM), and 50 control subjects of comparable age with normal glucose tolerance. The associations between cumulative GC dose and disease characteristics and glucose tolerance state, insulin sensitivity and β-cell function were tested using multivariate linear and logistic regression models, correcting for patient characteristics. Results Glucose tolerance state, insulin sensitivity and β-cell function did not differ between the two RA populations; de novo T2DM was detected in 11% and impaired glucose metabolism in 35% of patients with RA. In patients with RA, cumulative GC dose was associated with T2DM, which seemed mostly driven by the effects of cumulative GC dose on insulin resistance; however, the association decreased when corrected for current disease activity. Patients with RA had decreased insulin sensitivity and impaired β-cell function compared with controls, and multivariate regression analyses showed a negative association between the presence of RA and insulin sensitivity. Conclusions GC-using and GC-naive patients with RA had comparable metabolic parameters, and had decreased insulin sensitivity and β-cell function as compared with healthy controls. Although cumulative GC dose was shown to have a negative impact on glucose tolerance state and insulin sensitivity, confounding by indication remains the main challenge in this cross-sectional analysis.
