Refractory systemic onset juvenile idiopathic arthritis: current challenges and future perspectives.

Systemic juvenile idiopathic arthritis (SJIA) is a rare disease with distinct features not seen in other categories of juvenile idiopathic arthritis. In recent years, advances in the understanding of disease immunopathogenesis have led to improved targeted therapies with significant improvement in patient outcomes. Despite these advances, there remain subsets of SJIA with refractory disease and severe disease-associated complications. This review highlights existing options for treatment of refractory SJIA and explores potential future therapeutics for refractory disease.Key Points:Despite targeted Interleukin IL-1 and IL-6 inhibitors a subset of SJIA remains refractory to therapy. About 1 in 7 SJIA patients will be refractory to targeted IL-1 or IL-6 therapy.There is no current agreed upon definition for refractory SJIA and we propose in this review that refractory SJIA is presence of active systemic or arthritic features despite treatment with anti-IL-1 or anti-IL-6 therapy or disease requiring glucocorticoids for control beyond 6 months.SJIA disease associated complications include presence of associated macrophage activation syndrome (MAS), interstitial lung disease (ILD) or amyloidosis and management of each differs.Refractory SJIA treatment options currently include additional conventional synthetic disease modifying anti-rheumatic drugs (csDMARDS), biologic (bDMARDS), combination biologic therapy, targeted synthetic (tsDMARDS) or other immunomodulatory therapies.

Chronic recurrent multifocal osteomyelitis: diagnosis and treatment.

PURPOSE OF REVIEW: The aim of this article is to review recent findings regarding the diagnosis and treatment of chronic recurrent multifocal osteomyelitis (CRMO). RECENT FINDINGS: An adequate understanding of pathophysiology along with the new advances in MRI imaging make it possible to determine the extent of disease and establish early treatment. TNF-α inhibitors and bisphosphonates have shown to be a well-tolerated and efficient treatment for CRMO providing both symptomatic relief and normalization of bone morphology. SUMMARY: The results of recent studies suggest that a better knowledge of the genetic and molecular factors will allow early diagnosis and the development of more effective individualized treatments in the future.

Challenges to Practicing Pediatric Rheumatology.

Pediatric rheumatology is an exciting and rewarding career area. However, challenges when attracting trainees to this field include practice often occurring in smaller groups compared with general pediatrics, available positions requiring relocation, and fluctuation in funding resulting in uncertainty regarding training positions. Having critical mass in pediatric divisions is important to ensure adequate mentoring and people power to produce scholarly work, reduce on-call frequency and mitigate faculty absences that result in unplanned addition of clinical work. Compensation has historically lagged behind that of general pediatrics. Increased research opportunities through organized networks, patient and parent engagement, and the increasing recognition of pediatric rheumatologists as contributing to scholarship has heightened the profile of pediatric rheumatology nationally and internationally.
