Clinical trials

Fabry disease is a rare genetic disorder affecting 1 in 10,000 individuals, leading to complications such as chronic pain, heart and kidney failure, and strokes, ultimately impacting life expectancy. People with this disease are increasingly being diagnosed later in life, around the age of 65, as the condition progresses slowly with irreversible organ damage. The effectiveness of treatments for Fabry disease remains controversial, but early initiation is recommended for long-term benefits. Despite the high cost and inconvenience of treatments, there is limited research on their efficacy in older people or on the quality of life for those aged 65 and over with Fabry disease. This study aims to assess the quality of life in this age group both with and without treatment over a period of 5 years to determine the benefits of treatment beyond the age of 65.

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).

The goal of this clinical trial is to optimise and facilitate screening for Acid SphingoMyelinase Deficiency (ASMD) disease, by evaluating acid sphingomyelinase activity and, where appropriate, LysoSM levels in a cohort of 200 participants with diffuse interstitial lund disease (ILD) at risk of developing ASMD disease. ILD is common in the general population, so in order to limit the number of differential diagnoses, the population to be studied will be restricted to participants aged between 15 years and 3 months and 60 years, with ILD plus ground-glass opacities on chest CT scan certified by a pulmonologist/radiologist or internist, AND splenomegaly or splenectomy, and/or thrombocytopenia, and/or low HDL cholesterol, and/or parental consanguinity which increase the sensitivity of ASMD screening. In this clinical trail, two procedures are added, participants will be asked for : * a blood sample to measure the acid sphingomyelinase enzyme activity and LysoSM, if required. * a follow-up visit at 6 months
