About

X-linked Adrenoleukodystrophy (X-ALD) is one of the most frequent inborn error of metabolism caused by mutations in the ABCD1 gene, which codes for the transporter of saturated very long-chain fatty acids (VLCFA) for peroxisomal degradation, thus causing their toxic accumulation in body fluids and tissues. The clinical spectrum ranges from adrenal insufficiency without neurological symptoms to a rapidly progressive, fatal cerebral demyelinating disease that may occur in childhood as well as later in life. The most frequent phenotype in adulthood is adrenomyeloneuropathy (AMN), a slowly progressive myelopathy and peripheral neuropathy, which may also be prevalent in up to 80% of females carrying the X-ALD gene defect. Since signs and symptoms in females are usually milder and with a later onset, they are frequently underestimated, overlooked or misinterpreted, e.g. as Multiple Sclerosis. Consequently, many women with X-ALD do not receive adequate treatment.

Against this background, the development of new therapeutic interventions with the help of eHealth technology (e.g., counselling and treatment via digital communication tools) is of particular relevance, as it provides cost-effective, regular care even for patients who live remote from Leukodystrophy clinics.

The aims of this study is to evaluate the effectiveness of a multi-approach intervention ("SMART-ALD") on physical and mental well-being and quality of life in n=30 X-ALD symptomatic heterozygous females compared to a waiting list control group (n=30) using electronic health (ehealth) technology.
