Is this trial a fit for you?

Likely a good fit

Children aged 6 to under 9 years who were treated with allogeneic HSCT for a primary immunodeficiency at Necker Hospital and are at least two years post-transplant.

Probably not a fit

Children who do not meet the age window, were transplanted for non-PID conditions, or are unable to participate in assessments may not benefit.

What this trial studies

This observational study follows children aged 6 to just under 9 years who underwent allogeneic hematopoietic stem cell transplantation for a primary immunodeficiency at least two years ago. The assessment focuses on neurocognitive, psychological, and psychosocial functioning during a routine follow-up day hospital visit at Necker-Enfants Malades Hospital in Paris. The pilot aims to describe the multidimensional outcomes and identify potential factors associated with long-term well-being after transplantation. Enrollment is limited to patients treated at the Necker hospital who meet specific age and language criteria, with informed consent from guardians. No experimental interventions are being tested; standardized assessments are used to characterize outcomes over time.

Why it matters

Potential benefit: Findings could inform care plans and support services to improve long-term cognitive and psychosocial outcomes for children after stem cell transplantation.

How similar studies have gone: Past research on long-term psychosocial effects after HSCT in children exists mainly for cancer patients; this study addresses a gap in PID-specific, long-term outcomes with a similar observational approach.
