OBJECTIVE: Rheumatoid nodules (RN), a classic cutaneous extra-articular manifestation of rheumatoid arthritis, can often cause discomfort or cosmetic embarrassment. This research determined the effectiveness and complications of corticosteroid injection of the RN.
METHODS: Using a repeated measure design, 66 consecutive symptomatic RN were measured, underwent corticosteroid injection with 1 to 2mL of a 50:50 mixture of 1% lidocaine and triamcinolone acetonide (20-40mg), and then reassessed at four months for softening, reduction in size, and complications, including infection.
RESULTS: The mean age of our patient group was 53.3±10.6 years; 45 percent were Hispanic, 55 percent were non-Hispanic White, 100 percent were seropositive (rheumatoid factor and/or anti-CCP antibody), and 87.5 percent were female. Baseline mean RN diameter was 0.50±0.51cm and four months after injection was reduced to 0.29±0.33cm (decreased 42% or 0.21±0.57cm reduction, 95% CI: 0.46 <0.21< 0.37, p=0.013), 100 percent (66/66) were less painful, and 77 percent (51/66) were palpably softened. However, 70 percent (46/66) demonstrated cutaneous atrophy and/or hypopigmentation at four months, 53 percent (35/66) nodules recurred within 12 months, and 47 percent (31/66) nodules were eventually surgically removed.
LIMITATIONS: Two (3%) of the larger RN (2.5cm on the olecranon and 2cm on the 2nd toe) became infected and failed antibiotic therapy, necessitating surgical excision for complete resolution.
CONCLUSION: For short-term symptomatic relief, smaller RN can be safely injected with triamcinolone. Large symptomatic RN (≥2cm) are at greater risk of infection; thus, in these cases, lower corticosteroid doses or surgical excision may be preferred. In the long-term, effective systemic antirheumatic therapy with treat-to-target is the best approach.
