3. 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.
4. 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.
5. 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
6. 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.
7. 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.

18. 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.
19. 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.

31. 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.
32. 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.
Health Impact of Rheumatoid Arthritis
Rheumatoid arthritis (RA) is an autoimmune disease that causes joint inflammation and progressive erosion of bone, leading to joint misalignment, loss of function, and disability.
RA affects 1.3 million American adults. Onset occurs most often between the ages of 30 and 50 years. Women and older adults are more commonly affected.

Summary of Results: Head-to-Head Comparisons of Biologic DMARDs
Head-to-head comparisons of biologic DMARDs were evaluated for the effectiveness review. Patient populations in the included studies were patients with active RA for longer than 3 years whose disease not did respond or inadequately responded to DMARDs but had not previously treated with an anti–TNF-α DMARD. This table presents a summary of the results of those studies, organized according to the interventions compared in each study. Disease activity and symptom response, functional status, and quality-of-life outcomes were reported. Radiographic evidence of progression was not reported in the studies. The evidence is limited for all comparisons; thus, the strength of evidence is low or insufficient.

Summary of Results: Head-to-Head Comparisons of Oral and Biologic DMARDs
The reviewed studies included direct comparisons of oral and biologic disease-modifying anti-rheumatic drugs (DMARDs) used to treat patients with longstanding active rheumatoid arthritis who required a change in therapy. A retrospective cohort study of 1,083 patients found that as a class, biologic DMARDs resulted in more remissions when compared with oral DMARDs as a class. The systematic review found that biologic DMARDs achieved a higher response rate than oral DMARDs. The strength of evidence for this finding is moderate.
Four randomized controlled trials and two retrospective cohort studies evaluated 3,696 patients in comparisons of biologic DMARDs with oral DMARDs. Higher symptom response rates were found with biologic DMARDs. The strength of the evidence for this conclusion is moderate.
Radiographic evidence of progression was not reported in the studies presented here, and evidence for findings of effect on functional capacity was insufficient to permit conclusions.

Summary of Results: DMARD Combinations Versus Monotherapies
In patients with longstanding active rheumatoid arthritis with inadequate disease control, head-to-head comparisons were made of combined DMARDs and DMARD monotherapy. Overall, combination treatment with biologic DMARDs and an oral DMARD is more effective than either used as monotherapy. Disease activity, radiographic progression, functional status, and quality of life all are greater improved with the combination therapy. The strength of evidence for these findings varies among the specific outcomes, with most supported by moderate or high strength of evidence.

Summary of Results: DMARD Combinations Versus Monotherapies
In patients with early rheumatoid arthritis who had not been treated with methotrexate (MTX), or who had not received MTX in the previous 3 months, head–to–head comparisons of combination therapy and MTX monotherapy were examined for effects on function and quality of life. Combination therapy was more effective in achieving improvements in function and quality of life. The strength of evidence is moderate for functional status and low for quality of life.

Summary of Results: Comparative Benefits of DMARDs for Patients With Early RA
Some clinical research has focused on treatment of patients with early rheumatoid arthritis, defined for this comparative effectiveness review as less than 3 years’ duration of disease. This table presents a summary of the results of those studies, organized according to the patient characteristics and by the interventions compared in the study. Disease activity and symptom response, radiographic evidence of progression, and functional status were reported. Quality-of-life outcomes were not reported in the studies. The strength of evidence is moderate for one conclusion, finding that methotrexate and adalimumab or etanercept produce similar effects on symptoms. The evidence is limited for all other comparisons, making the strength of evidence low.

Comparative Adverse Effects of Combining DMARDs
Combining methotrexate (MTX) or other oral disease-modifying anti-rheumatic drugs (DMARDs) with a biologic DMARD does not alter the adverse event rate found with the biologic DMARD alone. The strength of evidence for this finding is low.
Combining MTX and biologic DMARDs demonstrates a better tolerability profile than MTX alone. The strength of evidence for this finding is low.
Evidence is insufficient to estimate differences in rates of specific adverse events between the biologic and oral DMARDs.
