Session Information
Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
Background/Purpose:
Early and intensive treatment with DMARDs are essential for
remission induction in newly diagnosed RA patients. However, demographic,
psychosocial and disease related factors may play a role as well.
Objectives:
To investigate which demographic, psychosocial and disease
related factors are associated with attaining remission at two consecutive
visits in early RA patients treated in a treat-to-target manner
Methods:
We used 2 years follow-up data
from patients participating in the tREACH trial1,2 in which
induction therapy strategies were compared: (A) combination high dose
conventional therapy ((MTX + sulfasalazine + hydroxychloroquine or (B) MTX.
Both groups had glucocorticoid (GCs) bridging. Disease activity (DAS) was
assessed every 3 months. Remission was defined as DAS<1.6 at 2 consecutive visits
(3 months). Univariate and multivariate logistic regression analyses were
performed including demographic, disease related and psychosocial factors
evaluated at baseline as predictors for attaining remission during 24 months of
follow-up.
Results:
281 patients (68% female; mean DAS 3.4, median HAQ 1.00) were
included. During 2 years of follow-up, 139 of 281 (49%) patients (group A: 93
(51%), group B: 46 (47%)) attained remission at 2 consecutive visits.
Univariate analysis revealed that older age and female sex were associated with
a lower chance of attaining remission (demographic factors). Similar relations
were observed for higher DAS, HAQ and worse physical functioning (disease
factors) and higher levels of anxiety, depression, fatigue and passive coping
with pain (psychosocial factors). In multivariate analysis within blocks of
covariates, age and sex maintained significance in the block of demographic
factors, DAS and ACPA positivity in the block of disease factors and fatigue in
the block of psychosocial factors. In the final model combining the independent
block predictors, age, sex and fatigue remained significant.
Conclusion:
In the tREACH trial, 50% of early RA patients attained remission
within 2 years of follow-up. Older age, female sex, higher baseline DAS, ACPA
positivity and fatigue were important predictors for not attaining remission,
but in the final model only age, sex and fatigue remained. Results suggest that
high levels of fatigue may prevent patients from attaining remission despite treatment
according to a tight control and treat-to-target strategy.
