Background: Juvenile idiopathic arthritis (JIA) is a common chronic rheumatic disease in children, requiring careful management to reduce both short- and long-term morbidity. In this study, our objective was to assess the clinical features of patients diagnosed with JIA who received intra-articular corticosteroid injections (IACI)., Methods: In this retrospective study, we evaluated the clinical and laboratory characteristics of 225 JIA patients monitored from January 2012 to October 2023 at a tertiary care center. We focused on patients who underwent intra-articular corticosteroid injections (IACI) as part of their treatment. Triamcinolone hexacetonide (TH) was used due to its demonstrated safety and efficacy., Results: Our analysis revealed that IACI, particularly utilizing TH, was a widely employed and effective adjunct therapy, contributing to rapid symptom relief and local disease control. Patients receiving IACI exhibited earlier symptom onset, younger age at diagnosis, longer follow-up durations, and higher cumulative treatment burden ( p  < 0.001, p  < 0.001, p  < 0.01, p  < 0.001 respectively). Despite inconclusive acute-phase reactants, a higher frequency of ANA positivity and elevated initial lymphocyte counts were associated with increased IACI use ( p  < 0.001, p  < 0.001 respectively). Importantly, on a joint basis, a high percentage of arthritis remission following IACI underscores its efficacy and favorable safety profile., Conclusions: Notably, the high percentage of arthritis remission achieved with intra-articular corticosteroid injections (IACI) on a joint-specific basis highlights its efficacy and favorable safety profile. A lymphocyte count exceeding 5000/mm 3 at the time of diagnosis may serve as an early indicator for considering intra-articular steroid administration. These findings emphasize the need for nuanced and individualized treatment strategies in JIA management to optimize outcomes for affected children.
