A diagnostic, prognostic, and treatment decision tool for children with autoimmune and inflammatory primary immune disorders

Conception of a Diagnosis, Prognosis and Therapeutic Decision Tool for Patients With Autoimmunity and Inflammation

Observational Institut National de la Santé Et de la Recherche Médicale, France · NCT04902807

This project will try to use blood and other samples to find molecular patterns that help diagnose, predict outcomes, and guide treatment for children with primary immune deficiencies that cause autoimmunity and inflammation.

What this trial studies

The project collects biological samples from pediatric patients with genetically defined primary immunodeficiencies (PIDs) who present with autoimmune or inflammatory complications, along with unaffected control relatives and unrelated subjects. Investigators will apply multiple omics technologies—transcriptomics, epigenomics, proteomics, metagenomics, metabolomics and lipidomics—to identify molecular signatures linked to diagnosis, prognosis and therapeutic response. These multi-omics data will be integrated to build algorithms intended to classify molecular causes, predict disease trajectories, and support therapeutic decision-making. The work is centered at Hôpital Necker-Enfants Malades and focuses on children under 18 with known genetic PID defects and autoimmune/inflammatory manifestations.

Who should consider this trial

Good fit: Children under 18 treated at Hôpital Necker-Enfants Malades with genetically confirmed PIDs and autoimmune or inflammatory manifestations who weigh more than 9 kg, have health insurance, and whose parents can provide informed consent are ideal candidates.

Not a fit: Adults, children without monogenic PIDs or without autoimmune/inflammatory symptoms, patients not treated at Necker, or those unable or unwilling to provide samples or consent are unlikely to benefit from this project.

Why it matters

Potential benefit: If successful, the tool could enable earlier and more precise diagnoses, better prediction of disease course, and more personalized treatment choices to reduce severe complications in affected children.

How similar studies have performed: Genomic and transcriptomic research has already identified many monogenic PID causes and shown variable clinical presentations, but fully integrated multi-omics diagnostic and decision-support tools are still emerging and not yet widely validated for routine care.
