Follow-up care for new cases of polyarthritis in children and young adults

Medical Follow-up of New Cases of Polyarthritis in Children and Young Adults. Optimization of Clinical Response, Remission, Quality of Life and Analysis of Prognostic Markers

Observational Université Catholique de Louvain · NCT07000916

This program will try standardized medical follow-up for children and young adults (≤50) with new-onset JIA, RA, psoriatic/seronegative/undifferentiated arthritis, SLE, or diffuse systemic sclerosis who are treatment-naïve or treated ≤3 months to see if more patients reach disease control or remission.

What this trial studies

This observational program will enroll young patients (up to 50 years) newly diagnosed with juvenile idiopathic arthritis, rheumatoid/psoriatic/seronegative/undifferentiated arthritis, systemic lupus erythematosus, or diffuse systemic sclerosis who are treatment‑naïve or treated ≤3 months (except JIA). Participants will be organized into five disease cohorts and undergo standardized clinical monitoring with predefined response and remission criteria based on international definitions. The project seeks to progressively increase capture of new incident cases—targeting 25% initially with a 20% annual increase over 5–10 years—to harmonize care across the participating French‑speaking university centers. Primary outcomes include the proportion of patients achieving good disease control or clinical remission under the standardized follow‑up.

Who should consider this trial

Good fit: Children and young adults aged ≤50 with a new diagnosis of JIA, RA, psoriatic/seronegative/undifferentiated arthritis, SLE, or diffuse systemic sclerosis who are treatment‑naïve or have received basic therapy for ≤3 months (except JIA) are ideal candidates.

Not a fit: Patients treated for more than 3 months, older than 50, or with established long-standing disease are unlikely to benefit from the early standardized follow-up targeted here.

Why it matters

Potential benefit: If successful, this approach could increase the number of young patients who achieve good disease control or clinical remission through earlier, standardized follow-up and care.

How similar studies have performed: Early-treatment and standardized monitoring approaches have improved remission rates in RA and JIA in prior work, though combining multiple pediatric and young adult rheumatic diseases in a single standardized program is less commonly studied.
