Summary

The goal of this study is to describe the natural history of ASMD in adult and paediatric patients with or without specific treatment in order to assess the impact of the disease on their daily lives and quality of life. The population concerned corresponds to patients aged at least 2 years, with a definite diagnosis of ASMD as determined by a confirmed low acid sphingomyelinase assay and who have not expressed their opposition to participating in this research (patients and/or parental authority).

Detailed description

Niemann Pick A/ AB/ B disease also known as acid sphingomyelinase deficiency (ASMD) is a very rare genetic disease. The natural history remains poorly understood. This disease leads to morbidity and mortality. A specific effective treatment has been available since 2023. The Internal Medicine Department of the Groupe Hospitalier Diaconesses Croix Saint-Simon (GHDCSS), reference center for lysosomal diseases, develops this clinical study in order to better understand the natural history of Niemann Pick A/ AB/ B disease, and better manage the symptoms, the complications and also the impact of this new treatment, particularly on daily life (quality of life). This French multicenter cohort research is coordinated by Dr Wladimir MAUHIN, (Internal medicine department, GHDCSS, Paris).
