Our topic
Rheumatoid arthritis (RA) is a systemic autoimmune disease that causes joint inflammation and progressive erosion of bone, leading to joint misalignment, loss of function, and disability.
RA affects more 600.000 than million Indonesian adults. Onset occurs most often between the ages of 30 and 50 years. Women and older adults are more commonly affected.
Health Impact of Rheumatoid Arthritis
Donahue KE, Jonas D, Hansen RA, et al. Comparative Effectiveness Review No. 55. Available at www.effectivehealthcare.gov/dmardsra.cfm.
The goal of RA treatment is to: Control pain & inflammation Limit progressive damage Reduce disease activity or induce remission Maintain function
Treatment of Rheumatoid Arthritis
Donahue KE, Jonas D, Hansen RA, et al. Comparative Effectiveness Review No. 55. Available at www.effectivehealthcare.gov/dmardsra.cfm.
Disease-modifying anti-rheumatic drugs (DMARDs) interfere with rheumatoid disease processes by blocking the production or activity of the immune cells and their products that cause inflammation and damage.
Treatment with DMARDs is increasing with the expectation that they will lead to better disease control and more remissions.
Steroids—both low-dose systemic and intra-articular formulations—are used as adjuncts to DMARD treatment.
DMARDs
Disease-modifying anti-rheumatic drugs (DMARDs) are in common use for rheumatoid arthritis (RA), and several have been approved by the U.S. Food and Drug Administration for this indication.
DMARDs may be oral or biologic drugs. The consensus of clinical experience has made methotrexate, an oral DMARD, the first-line drug of choice for treating RA.
DMARDs in Rheumatoid Arthritis Treatment (1 of 2)
Donahue KE, Jonas D, Hansen RA, et al. Comparative Effectiveness Review No. 55. Available at www.effectivehealthcare.gov/dmardsra.cfm.
Oral disease-modifying anti-rheumatic drugs (DMARDs) are small-molecule chemical drugs. The mechanism of action of each of these drugs is not well defined and is unknown in some cases.
Biologic DMARDs block the activity of immunostimulatory cytokines and other cell-signaling molecules. Biologic DMARDs are genetically engineered antibodies and proteins. Tumor necrosis factor-alpha blockers are the most typical members of this drug class.
Other targets are interleukins 1 and 6 and the transmembrane proteins CD20 and CD28.

The strength of evidence for each of the following findings is low: Patients with moderate rheumatoid arthritis (RA) had better overall improvement and better functional status than patients with severe RA. However, patients with severe RA had the greatest degree of improvement from baseline.
In treatment with methotrexate (MTX), as the age of patients increased, the likelihood of major clinical improvement decreased slightly; however, overall age did not affect efficacy or risk of adverse effects.
Patient Characteristics on Outcomes of DMARD Treatment
Donahue KE, Jonas D, Hansen RA, et al. Comparative Effectiveness Review No. 55. Available at www.effectivehealthcare.gov/dmardsra.cfm.
Biologics showed no apparent influence on the risk of cardiovascular events in the elderly (≥65 years of age).
Toxicity of MTX was more likely in patients with greater renal impairment. High-risk comorbidities (cardiovascular disease, diabetes, malignancies, and renal impairment) did not increase the risk of serious adverse events or infections in patients treated with b-DMARDs.
Concomitant antidiabetic, antihypertensive, or statin medications given to patients treated with b-DMARDs did not increase the risk of adverse events.

Combining MTX and biologic DMARDs demonstrates a better tolerability profile than MTX alone. Strength of Evidence = Low

Apakah nyeri yang berkurang atau membaik menjadi poin yang paling utama dalam pencapaian goal of treatment di AR ? • Dari sisi pasien jawabannya: YA
• NYERI merupakan KELUHAN UTAMA disamping STIFFNESS pada pasien dengan RA
• Dari sisi dokter : disease control• Disease activity (inflammation)• Function• Disease damage

What To Discuss With Your Patients and Their Family
Donahue KE, Jonas D, Hansen RA, et al. Comparative Effectiveness Review No. 55. Available at www.effectivehealthcare.gov/dmardsra.cfm.
How to monitor Tt in RA?• Disease activity is assessed by several parameters…• Duration of morning stiffness• Tender joints count• Swollen joints count• Observer global assessment• Patient global assessment• Visual analogue scale for pain• Health assessment questionnaire• ESR• NSAID pill count etc
• Patient on MTX, SSZ or leflunamide show clinical improvement in 6-8 wks.• Patient should be observed for 6 months before declaring a DMARD ineffective.
How long should Tt. be continued?• Once remission is achieved , maintenance dose for long period is recommended.• Relapse occurs in 3-5 months (1-2 months in case of MTX) if drug is discontinued in most instances.
• DMARDs are discontinued by patients because of toxicity or secondary failure(common after 1-2 yrs) and such patients might have to shift over different DMARDs over 5-10 yrs.
• Disease flare may require escalation of DMARD dose with short course of steroids.
Thank you.
