What Is the Best Treatment Strategy for Early Rheumatoid Arthritis?
Study Shows Long-Term Benefits of Initial Combination Therapy, including Either
Prednisone or Infliximab, Over DMARDs Alone or Step-Up Combination Therapy
A progressive, inflammatory disease affecting the joints and organs, rheumatoid
arthritis (RA) claims more than two million Americans, mostly women over age
40, among its victims. While a cure has yet to be found, the treatment of RA
patients has changed considerably over the last two decades. Today, the goal
of therapy is not simply symptom relief, but the prevention of long-term structural
damage and functional decline. Toward this end, various disease-modifying antirheumatic
drugs (DMARDs) have been proven effective in clinical trials, on their own
and in tandem with various tumor necrosis factor (TNF) antagonists. While the
recent increase in therapeutic options offers much promise, it has left doctors
grappling with the question: What is the best treatment strategy for a patient
newly diagnosed with RA?
The results of a long-term study, featured in the November 2005 issue of Arthritis & Rheumatism (http://www.interscience.wiley.com/journal/arthritis),
provide clear answers. A team of researchers in the Netherlands compared the
four most widely sanctioned and commonly prescribed treatment strategies for
very early RA on 508 patients. Primarily women, with a mean age of 54, the
patients had suffered disease symptoms for an average of 23 weeks before entering
the trial. After randomly assigning the patients to one of four treatment strategies,
the researchers closely monitored the effects and benefits for each group over
the course of one year.
Group 1 (126 patients) received standard DMARD therapy, starting with methotrexate.
Group 2 (121 patients) was assigned to step-combination therapy, starting with
methotrexate only, adding other DMARDs and prednisone. Group 3 (133 patients)
started with a combination of methotrexate, sulphasalazine and prednisone.
Group 4 (128 patients) started with a combination of methotrexate and infliximab.
For all groups, drug dosages were increased or switched to other (combinations
of) drugs according to the treatment protocol to achieve a state of low disease
activity.
At the end of the year, every group demonstrated measurable improvements,
with 32 percent of all the patients achieving clinical remission of their disease.
However, patients who had received initial combination therapy—either with
prednisone (group 3) or with infliximab (group 4)—had significantly less progression
of radiographic joint damage than did patients treated with DMARDs only (group
1), or patients assigned to step-up combination therapy (group 2). The number
of patients without any progression of radiographic joint damage was also higher
in groups 3 and 4 than in groups 1 and 2. Furthermore, RA patients in both
initial combination therapy groups experienced earlier functional improvement
than did patients in either the DMARD monotherapy or step-up combination therapy
group, according to scores of the Dutch version of the Health Assessment Questionnaire.
Overall, patients who received initial combination therapy experienced no more
side effects than patients in the other two groups.
“Patients in groups 3 and 4 had the benefit of a more rapid relief of symptoms
and improvement of physical function,” observes the author, B. A. C. Dijkmans,
M.D. “In addition, there is the possibility that effective suppression of disease
activity during the early phases of the disease may ameliorate the long-term
joint damage and poor physical function and, ideally, even induce true clinical
remission without the need for ongoing DMARD treatment.”
Should any patient with newly diagnosed RA be treated with a single DMARD?
Would choosing this established course always make a patient vulnerable to
increased disease severity? That question can only be answered with further
research.
