Characterization of Neuromuscular Involvement in Late Adolescent and Adult Cystinosis Patients
Characterization of Neuromuscular Involvement in Late Adolescent and Adult Cystinosis Patients
The primary objective of the study is to evaluate the change in motor function of patients with cystinosis.
The secondary objectives of the study:
All patients will be examined by experienced neuromuscular specialist (Pr Pascal Laforêt) and pulmonologist specialized in neuromuscular disorders (Pr Hélène Prigent). All evaluations will be performed in Raymond-Poincaré hospital (Teaching hospital of Assistance Publique - Hopitaux de Paris (APHP) and University of Paris-Saclay) neuromuscular center, coordinated by Pr Pascal Laforêt.
This is a monocentric study. The enrollment will be performed as routine care in the department of neurology - neuromuscular center of Raymond Poincaré hospital (APHP).
Patients with cystinosis will be consecutively invited to participate in the study until 20 patients are included. This will avoid selection bias if any. For eligible non included patients, a specific non-identifying registry will be set-up with a very restricted number of variables indicative of disease severity at baseline, allowing for a comparison of included and non-included patients.
Participating cystinosis patients will be proposed to attend a one-day hospitalization. Evaluations will be performed during stable state upon baseline and during a follow-up visit 12 months later.
The study expected duration is 30 months with 18 months for patients' inclusion and 12 month-follow-up.
