BACKGROUND: Leflunomide, a novel immunoregulatory drug, has been shown to be effective in rheumatoid arthritis (RA) as monotherapy and as combination therapy with methotrexate (MTX). The aims of this study were to investigate the efficacy and safety of combination therapy with leflunomide and MTX in active RA patients and to identify the patients with a better response to this combination. METHODS: The patients received a maintenance dose of 20 mg of leflunomide with or without a loading dose. Parameters for disease activity in RA were measured at baseline and at 12 and 24 weeks after initiation of leflunomide. At 24 weeks, the baseline data from the patients classified as leflunomide responders were compared with data from nonresponders and analyzed to determine the potential predisposing factors for treatment response. RESULTS: A total of 103 patients with RA were included and 93 (90.3%) patients received leflunomide for 24 weeks. At 24 weeks, 67 (65.1%) patients were DAS28 responders; 14 (13.6%) were good responders and 53 (51.5%) moderate responders. At 12 weeks, significant improvements were noticeable in the individual efficacy measures of diseases activity. There were also significant improvements between 12 and 24 weeks in swollen joint count, tender joint count, HAQ disability index, and patients' and physicians' global assessments of diseases activity; but no further improvements in ESR or CRP could be seen after the first 12 weeks. When comparing the baseline data from responders with the nonresponders, patients on a higher MTX dose and patients with a higher disease activity at baseline responded better to leflunomide. However, age, sex, disease duration of RA, functional status, loading dosage of leflunomide, and previous number of DMARDs used did not affect the patients' response to leflunomide. CONCLUSION: Combination therapy with leflunomide and MTX is effective and safe across a wide range of patients, especially those with a high disease activity in spite of treatment with other traditional DMARDs.

3.Recent trends and guidelines for the management of rheumatoid arthritis.
Korean Journal of Medicine 2009;76(1):18-24
The paradigm for the management of rheumatoid arthritis (RA) has shifted in the past two decades. The appreciation of increased mortality in patients with RA and the poor outcomes with conventional therapy led to the concept of the early aggressive treatment to suppress ongoing inflammation and prevent joint injury. RA results from acute and chronic inflammation in the synovium associated with proliferative and destructive processes in the joint. Affected areas may either heal without structural defects, or be irreversibly damaged if inflammation is severe and does not remit. Therefore, measures aimed at identifying early active disease and ameliorating inflammation are essential and may be highly effective in modifying disease outcome. The goal of treatment is to achieve and maintain a state of remission or, at the least, a state of low disease activity, in order to prevent joint damage and disability. This requires the initiation of treatment early in the disease process, as well as vigilant monitoring throughout the course of disease, with prompt readjustment of therapy, for flares of activity and for medication toxicity. This aggressive approach has been made possible by the increasing number of effective non-biologic and biologic disease-modifying anti-rheumatic drugs (DMARDs). Recent trends and guidelines for the management of RA are presented here.

4.Ultrasonographic Assessment in Rheumatoid Arthritis.
The Journal of the Korean Rheumatism Association 2009;16(2):74-86
The administration of disease-modifying antirheumatic drugs (DMARDs) in the early period of rheumatoid arthritis (RA) is critical for protecting against joint damage and inducing remission. Physicians need to identify patients at risk of progression to RA at the early stages of arthritis. Musculoskeletal ultrasonography (MSUS) allows the direct visualization of synovitis and bone erosion in the early phase, and may be useful for differentiating early rheumatoid arthritis from other inflammatory arthritis. Power Doppler sonography is a promising tool for assessing the disease activity and monitoring the effects of DMARDs. This article reviews the current status and recent advances in MSUS imaging in RA.

5.Disease Modifying Antirheumatic Drugs in Rheumatoid Artritis.
Hanyang Medical Reviews 2005;25(2):73-79
Rheumatoid arthritis (RA) is a chronic progressive disease, affecting an estimated 1% of the population worldwide. Although the optimal care of RA patients requires various modalities, pharmacotherapy remains the cornerstone of treatment for RA. Clinical studies in patients with RA have broadened understanding of its pathogenesis and have fundamentally changed the therapeutic approach to this disease in the last 10 years. It has become clear that early suppression of RA disease activity is important in preventing progressive joint destruction and functional decline. There has been a complete remodeling of the traditional "therapeutic pyramid" by rheumatologists, who now treat RA earlier and more aggressively than ever before, using combinations of classic disease-modifying antirheumatic drugs or new drugs. Although a cure remains elusive, remission is an approachable goal.

6.Medical treatment of rheumatoid arthritis (I): Nonsteroidal anti-inflammatory drugs, disease modifying antirheumatic drugs and glucocorticoids.
Journal of the Korean Medical Association 2010;53(10):871-879
The medical treatment of rheumatoid arthritis has been dramatically improved with the advances of newer disease-modifying antirheumatic drugs (DMARDs) and biologic agents during previous decades. To prevent joint damage, it is essential to start DMARD treatment early, especially within the first 3 months after diagnosis. Tight control of disease activity, and the thorough monitoring of the treatment's efficacy and the side effects of medications are also important. Nonsteroidal anti-inflammatory drugs (NSAIDs) are usually used to control pain and swelling of the joints. However, these drugs cannot alter the disease course of rheumatoid arthritis. It is therefore necessary to introduce DMARDs at the beginning of treatment, and, after achieving the effect of DMARDs, NSAIDs should be tapered as soon as possible. The main treatment should be DMARDs, which must be used wisely and appropriately. It is also important to adjust DMARD therapy during the course of treatment according to disease activity. Glucocorticoids have potent anti-inflammatory effects and can control inflammation dramatically. However, because of the diverse and serious side effects of glucocorticoids, the usage of glucocorticoids should be limited to low-dose oral therapy or intra-articular injection, unless otherwise indicated. Along with biologics, there are now various weapons available against rheumatoid arthritis, and it can be treated much more effectively than before.

OBJECTIVE: The aim of this study was to examine clinical characteristics of Korean rheumatoid arthritis (RA) patients with clinically indications for TNF-alpha blocker, and to compare their clinical parameters with the Korean National Health Insurance reimbursement criteria. METHODS: Data were obtained from a registry of RA patients who visited rheumatology clinics of Hallym University affiliated hospitals. Among patients who were previously prescribed DMARDs for more than three months, rheumatologists selected patients clinically indicated for TNF-alpha blocker. The clinical characteristics at the time TNF-alpha blocker use was deemed indicated were examined. Radiographic damage was quantified by Modified Sharp van der Heijde score in hand and foot simple AP radiograph. RESULTS: From August 2010 to January 2013, five rheumatologists in four hospitals selected 109 patients clinically indicated for TNF-alpha blocker. When TNF-alpha blocker was considered, mean DAS28 was 5.2 (range 2.1~8.05), mean swollen joint count was 6 (range 0~22), mean tender joint count was 10.6 (range 0~28), mean ESR was 43.2 mm/hr (range 1~140) and mean CRP was 2.5 mg/dL (range 0.1~18.3). The mean total modified Sharp van der Heijde score was 32.72 (range 0~240). Eighty one percent of subjects did not have enough active joints to satisfy the Korean National Health Insurance reimbursement standard. CONCLUSION: Our results show that patients with clinically indications for TNF-alpha blocker had a broad range of disease activity and clinical parameters, and the majority did not meet the Korean National Health Insurance reimbursement criteria.

BACKGROUND: Biologic disease-modifying antirheumatic drugs (bDMARDs) extend the treatment choices for rheumatoid arthritis patients with insufficient response or intolerance to conventional DMARDs (cDMARDs). These agents have considerable efficacy compared with conventional DMARDs, but only a few head-to-head comparisons among these agents have been performed. The objective of this systematic review and network meta-analysis (NMA) was to compare the relative efficacy of Certolizumab with conventional DMARD to licensed bDMARD with cDMARD therapy for patients who failed to prior cDMARD treatment under the condition of the reimbursement coverage criteria in Korea. METHODS: A systematic review was conducted using MEDLINE and Cochrane library. Key endpoints were the American College of Rheumatology (ACR) responses of 20/50/70 at six months. Bayesian outcomes were calculated as median of treatment effect, probability of the best, Odds Ratio (OR) and probability that OR was greater than one. RESULTS: Compared with other bDMARDs, Certolizumab were associated with higher or comparable ACR response rates; in ACR20, the OR (probability of OR>1) was 2.08 (92.6%) for Adalimumab, 1.86 (85.7%) for Etanercept, 1.89 (79.5%) for Golimumab, 2.36 (92.1%) for Infliximab, 1.79 (87.0%) for Abatacept, 1.74 (80.8%) for Rituximab and 1.82 (86.8%) for Tocilizaumab. In ACR50 and ACR70, the ORs did not present significant differences. CONCLUSION: Certolizaumab with cDMARD was more effective or comparable than other bDMARDs in patients who failed prior cDMARD treatment.

9.Paradigm Shifting to Early Treatment of Rheumatoid Arthritis.
Journal of the Korean Medical Association 2003;46(11):965-971
The past decade has greatly enhanced our understanding of rheumatoid arthritis (RA). Not only have new drug therapies become available, but this period has witnessed dramatic changes in treatment strategies as well. Since 1989, when the proposal on reversing the pyramid approach (the step-down bridge concept) was published, the concept of early and aggressive treatment of RA has become the leading paradigm. The theory underlying this approach is based on a bet-ter understanding of the devastating long term consequences of RA in most patients, and the logical tenet that irreversible damage must be prevented before it occurs. Evidence has shown the irreversible joint damage in RA occurs early in the disease, making a "wait and see" approach unacceptable. Thus, it appears logical to begin treatment as soon as a diagnosis of RA is confirmed, to slow disease progression by treatment with disease modifying antirheumatic drugs. This review will address the evidence supporting the benefit and the principles of early treatment, as well as the current update on pharmacological management in early RA.

PURPOSE: We investigated whether Tc-99m MIBI imaging is useful to predict the response of drug treatment in patients with rheumatoid arthritis. MATERIALS AND METHODS: 24 patients (15 women and 9 men, age 49 +/- 12 year) rheumatoid arthritis and treated with disease modifying antirheumatic drugs (DMARDs) were included in this study. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured, and Tc-99m MIBI scan was obtained before drug treatment. Quantitative analysis of uptake in diseased joints was performed and expressed as joint-to background ratio (J/B) and percent retention (%R) of Tc-99m MIBI. Clinical symptoms were evaluated and graded from 0 (no) to 3 (severe) regarding to presence of tenderness and swelling. RESULTS: J/B of the diseased joints were significantly correlated with ESR and CRP (p< 0.05). A highly significant correlation was found between the improvement of clinical symptoms and %R of Tc-99m MIBI (p< 0.05). CONCLUSION: The results demonstrate that Tc-99m MIBI scan may be used to predict the therapeutic response in patients with rheumatoid arthritis.
