Cost-effective Tapering Algorithm in Patients with Rheumatoid Arthritis: Combination of Multibiomarker Disease Activity Score and Autoantibody Status.

OBJECTIVE: To analyze the effect of a risk-stratified disease-modifying antirheumatic drug (DMARD)-tapering algorithm based on multibiomarker disease activity (MBDA) score and anticitrullinated protein antibodies (ACPA) on direct treatment costs for patients with rheumatoid arthritis (RA) in sustained remission. METHODS: The study was a posthoc retrospective analysis of direct treatment costs for 146 patients with RA in sustained remission tapering and stopping DMARD treatment, in the prospective randomized RETRO study. MBDA scores and ACPA status were determined in baseline samples of patients continuing DMARD (arm 1), tapering their dose by 50% (arm 2), or stopping after tapering (arm 3). Patients were followed over 1 year, and direct treatment costs were evaluated every 3 months. MBDA and ACPA status were used as predictors creating a risk-stratified tapering algorithm based on relapse rates. RESULTS: RA patients with a low MBDA score (< 30 units) and negative ACPA showed the lowest relapse risk (19%), while double-positive patients showed high relapse risk (61%). In ACPA-negative and MBDA-negative (< 30 units), and ACPA or MBDA single-positive (> 30 units) groups, DMARD tapering appears feasible. Considering only patients without flare, direct costs for synthetic and biologic DMARD in the ACPA/MBDA-negative and single positive groups (n = 41) would have been €372,245.16 for full-dose treatment over 1 year. Tapering and stopping DMARD in this low-risk relapse group allowed a reduction of €219,712.03 of DMARD costs. Average reduction of DMARD costs per patient was €5358.83. CONCLUSION: Combining MBDA score and ACPA status at baseline may allow risk stratification for successful DMARD tapering and cost-effective use of biologic DMARD in patients in deep remission as defined by the 28-joint count Disease Activity Score using erythrocyte sedimentation rate.

German guidelines for the sequential medical treatment of rheumatoid arthritis with traditional and biologic disease-modifying antirheumatic drugs.

The German Society of Rheumatology approved new German guidelines for the sequential medical treatment of rheumatoid arthritis (RA) based on the European League Against Rheumatism (EULAR) recommendations for the management of RA published in 2010. An update of the EULAR systematic literature research was performed in Medline, Embase, and Cochrane databases. Meta-analyses, controlled trials, cohort studies, and registry data addressing traditional and biologic disease-modifying antirheumatic drugs, glucocorticoids, and treatment strategies published between January 2009 and August 2011 were included. Two reviewers independently evaluated and compared the additional data that had been published after the time limit set by the EULAR recommendations. A national guideline working group developed an adapted set of recommendations. The new German guidelines were accepted by vote using an informal Delphi approach. Twelve recommendations and the resulting updated treatment algorithm were developed and approved as a practical orientation for rheumatologists. These recommendations are based on a successive treatment with traditional and biologic disease-modifying drugs depending on the individual progress of the disease and distinct patient characteristics. The German guidelines have been developed on the basis of the internationally well-recognized EULAR recommendations. In addition, more recent evidence from a systematic literature research was considered. They have been developed and approved by a group of national experts aiming at guidance for rheumatologists to reach best medical practice.

Experiences with rituximab for the treatment of autoimmune diseases with ocular involvement.

OBJECTIVE: To report the efficacy of rituximab (RTX) in the treatment of ocular or orbital inflammation accompanying autoimmune diseases refractory to previous standard immunosuppressive therapy. METHODS: We reviewed medical records of 9 consecutive patients with noninfectious ocular or orbital inflammation treated with RTX. RESULTS: Over a mean followup of 42 months, 7 patients were in clinical remission, 1 had partial response to treatment, and 1 did not respond. Best corrected visual acuity improved ≥ 1 line in 4 patients, was stable in another 4 patients, and worsened in 1. Concomitant immunosuppressive therapy was tapered in 6 cases. Systemic corticosteroids were tapered or kept below 7.5 mg a day in 5 patients 1 year after the first RTX cycle. CONCLUSION: RTX therapy, in patients who are refractory to standard immunosuppressive therapy, was effective and showed a beneficial response to treatment including induction of clinical remission of inflammation in most patients.

Late aortic dislocation of a stent following stent angioplasty for ostial renal artery stenosis.

A patient with left RAS was treated by stent angioplasty followed by a multivessel percutaneous coronary intervention. Six months later, an aortic dislocation of the stent was diagnosed. The fully expanded stent was caught with a balloon catheter and fixed in the left external iliac artery. Stent migration after initially successful stent angioplasty for RAS is possible. Fully expanded, dislocated balloon-expandable stents can be secured by implanting them into the iliac artery.
