Objective. To compare patients with juvenile rheumatoid arthritis (JRA) injected with triamcinolone hexacetonide (TH) or triamcinolone acetonide (TA) with respect to time to relapse. Methods. This was a retrospective chart review of 85 patients: 51 patients with JRA who had received a joint injection with TH during the period June 2000-April 2001 and 48 patients who had received a joint injection with TA during the period May 2001-March 2002 who were followed for a minimum of 15 months, after an intraarticular steroid injection. Results. The primary endpoint variable for the study was the time to relapse of the arthritis in the affected joint following an intraarticular injection. A total of 227 joints were injected, 114 with TH and 113 with TA. In the TH group the mean time to relapse (± SE) was 10.14 ± 0.49 months compared to the TA group at 7.75 ± 0.49 months (p < 0.0001) using the log-rank test. A proportional hazards (Cox) regression analysis revealed no statistical association between sex, duration of illness, or type of arthritis and relapse time. An analysis was performed on the first intraarticular injection for each patient, with the average time to relapse for all joints injected of 10.36 ± 0.72 months for TH compared to 8.45 ± 0.78 months for TA (p < 0.02). A further analysis of the first knee injections showed a relapse time in the TH group of 11.11 ± 0.81 months compared to 7.95 ± 0.95 months for TA (p < 0.008). Conclusion. TH offers an advantage to TA, as there is a longer duration of action leading to an improved prolonged response rate in weight-bearing joints, particularly the knees. The results suggest that TH should be the intraarticular steroid of choice, particularly for the knee joint, in patients with JRA.
