Daily phone surveys to track the real-life burden of hereditary angioedema

Real-life Ecological Momentary Assessment of Lived Burden in Hereditary AngioEdema

Observational Istituti Clinici Scientifici Maugeri SpA · NCT07448181

The study will try daily phone surveys to see if they reveal a higher and more changeable burden of disease than standard questionnaires in adults with hereditary angioedema.

What this trial studies

This observational project asks adults with confirmed HAE to complete brief digital surveys each day for eight consecutive weeks using the m-Path app, plus standardized questionnaires. The approach uses ecological momentary assessment (EMA) to capture symptoms, mood, and perceived burden in real time rather than relying on memory-based reports. Researchers hypothesize EMA will show greater and more fluctuating burden than retrospective scales and better reflect everyday impact. No experimental treatments are given; the focus is on measurement and understanding patient experience.

Who should consider this trial

Good fit: Adults (≥18) with a confirmed diagnosis of HAE Type 1 or Type 2 who can give consent, have a compatible smartphone, and are willing to complete daily surveys for eight weeks are ideal candidates.

Not a fit: People with acquired or non-C1-INH angioedema, severe cognitive or psychiatric disorders that prevent independent questionnaire completion, children, or those without a compatible smartphone or unwilling to do daily surveys are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the approach could provide a more accurate picture of day-to-day burden in HAE and help clinicians and researchers tailor care and outcome measures to patients' real experiences.

How similar studies have performed: Ecological momentary assessment has been used successfully in other chronic illnesses to capture fluctuating symptoms, but its specific application to HAE is limited and relatively novel.
