Intraarticular corticosteroid injections in pediatric rheumatology: insights from specialists.

Unlabelled: Juvenile idiopathic arthritis (JIA) refers to various types of arthritis appearing before age 16, categorized into seven subtypes by ILAR. Treatments target disease control, growth support, and quality of life, utilizing NSAIDs, DMARDs, and intraarticular corticosteroid injections (IACIs). Despite IACIs' efficacy for oligoarticular JIA, their usage and techniques vary due to anecdotal evidence. This study compares IACI strategies among pediatric rheumatologists in Turkey and India as part of a PReS Sister Center activity. A cross-sectional survey via Google Forms gathered IACI practice data from pediatric rheumatologists in Turkey and India. The 33-item questionnaire covered demographics, JIA subtypes treated with IACIs, preferred agents/dosages, injection sites, follow-up, complications, anesthesia, and post-IACI treatments. Seventy clinicians' responses were analyzed, with ethical approval from Gazi University's Ethics Committee. Seventy participants, with a mean age of 39.75 (±8.80) years responded, mostly clinical fellows (38.6%) at university hospitals (58.6%). All utilized IACIs, primarily for oligoarticular JIA (100%), with 20% exclusively using them for this subtype. Triamcinolone hexacetonide (TH) was preferred (74.3%), mainly targeting knee joints (15.7%). Initial side effect follow-up was 1-2 weeks post-IACI (65.7%), with ultrasound guidance used by 17.1%. Common complications included cutaneous hypopigmentation (38.6%) and subcutaneous atrophy (38.6%). Ketamine was the favored anesthesia (44.2%). Post-IACI, 21.4% did not add treatment for new-onset oligoarticular JIA, while NSAIDs and methotrexate were common for polyarticular JIA (51.4%).

Conclusion: IACIs are widely utilized in pediatric rheumatology for oligoarticular JIA, yet practice variability exists. Standardized protocols through randomized studies can enhance IACI efficacy and patient outcomes.

What Is Known: • Intraarticular corticosteroid injections (IACIs) are a widely utilized and effective treatment modality in managing oligoarticular and polyarticular juvenile idiopathic arthritis (JIA), offering rapid symptom relief and the potential to prevent long-term joint deformities. • Despite their widespread use, there is significant variability in the indications, techniques, and anesthetic methods employed for IACI administration among pediatric rheumatologists, and much of the supporting evidence remains anecdotal.

What Is New: • This study highlights the diverse clinical practices and preferences regarding IACI use in pediatric rheumatology across two different countries, revealing considerable variations in the use of ultrasound guidance, anesthetic approaches, and corticosteroid formulations. • The findings underscore the need for standardized treatment protocols and further research to optimize IACI procedures, aiming to reduce variability and improve outcomes in the management of JIA.
