Clinical Trial Summary
Despite their efficacy at controlling joint inflammation, current treatments of rheumatoid
arthritis (RA) leave up to 40% of patients into non-remission.
Non-remission is most frequently due to persistently negative self-reported global impact of
RA, and not to remaining swollen joints or elevated levels of acute phase reactants. In a
cohort of recent-onset RA patients diagnosed early and treated to remission (Sherbrooke Early
Undifferentiated PolyArthritis (EUPA) cohort), treatment of active disease rapidly led to
reduced depressive symptoms in most, but 20% still expressed elevated depressive symptoms
(using the CES-D screening tool) after a mean of 7 months. Elevated CES-D scores at this
early time strongly predicted never reaching remission over the following 4 years. Elevated
CES-D scores were strongly correlated with increased levels of patient-related outcomes (PROs
such as fatigue, pain, sleep quality, stiffness and functional limitation), but not with
joint or systemic inflammation. In fact, 80% of patients expressing depressive symptoms had
controlled joint disease at the same visit. The investigators propose that addressing
depressive symptoms will improve RA patients' symptoms and quality of life. In clinical
practice, the best indicator of depressive symptoms is the presence of a disconnect between
the Patient's (Pt-VAS) and the Physician's (MD-VAS) evaluation of disease activity in
patients without objective signs of inflammation.
This pilot study will explore the feasibility and acceptability of testing MBSR in these
patients. It will assess over 6 months the changes in depressive symptoms and PROs both in
controls and MBSR-treated patients. If positive, the investigators plan to complete a
multicenter 6-month Randomized Clinical trial (RCT) (with a 2 year follow up) to formally
address the risks/benefits of group MBSR interventions in RA patients with controlled
inflammatory disease but positive disconnect between Pt-VAS and MD-VAS.
Description:
This is a pilot project for a pragmatic multisite, 6-month, two arm RCT of an MBSR
intervention in RA patients expressing depressive symptoms despite controlled joint
inflammation, on measures of depressive symptoms (Primary outcome). The investigators will
also explore the impact of MBSR on significant PROs (e.g. fatigue, pain, Pt-VAS, anxiety)
further translating into lower SDAI scores post-MBSR, and the feasibility of determining if
improvement may be mediated though better adherence to treatment and/or through a
modification of inflammation-related biomarkers.
During the present 1-year pilot study, the investigators propose to randomize 50 patients,
and offer 2 MBSR groups of ≈13 patients each. Due to the bidirectional relationship between
RA and depression, MBSR will be studied in patients receiving stable doses of arthritis
medications during remission or low disease activity. To avoid recruitment based on
thresholds of composite scores (e.g. SDAI) that are strongly impacted by depression-sensitive
variables, such as Patient global evaluation of disease activity (PtVAS) and tender joint
counts (TJC), the investigators will use a Swollen Joint Count (SJC) ≤2 out of 66 joints and
C-Reactive Protein (CRP) ≤8 mg/L ('objective' measures) to define controlled disease. As SJC
is the major determinant for RA treatment change in clinical practice, short-term RA
treatment changes are unlikely in the recruited patients.
Controlled RA patients reporting Pt-VAS superior to MD-VAS by at least 20/100 units will be
recruited. Blinded clinical assessors will determine the joint counts and the Examiner global
evaluation of disease activity (EVAS) to determine SDAI scores at baseline and at 6 months.
The French Canadian version of the CES-D and the Beck Depression Inventory to assess the
importance of depressive symptoms, as well as 0-100 VAS scales (fatigue; sleep; pain; PtVAS)
and Health Assessment Questionnaire (HAQ) will be obtained at both visits. Reporting will
conform to the CONSORT recommendations for pilot studies.
This study reflects clinical practice, where there is heterogeneity in duration of disease,
gender, age, type and dose of RA drugs used, as well as type and dose of antidepressants
(when used). While the investigators suggest that RA drugs remain constant over the 6-month
intervention period, treating physicians will be free to modify treatment if clinically
indicated. Antidepressant use will not be an exclusion criterion.
For pragmatic reasons (e.g. uneven availability and expertise of primary care physician's
(PCP), unknown effect size of the intervention), the investigators will not include a second
active treatment arm with optimization of antidepressants. Instead, the investigators will
inform in writing treating PCPs of their patient participation to the study and of the
disconnect between Pt-VAS and MD-VAS. Changes to arthritis and depression drugs will be
tracked and controlled for in analyses. For patients' safety, psychological contraindications
to MBSR will be screened at baseline during a phone interview by Dr Françoise Gendron who
will direct the MBSR sessions, and patients with contraindications excluded.
