Abstract
X-linked adrenoleukodystrophy is a rare, neurodegenerative peroxisomal disorder connected with mutation in the ABCD1 gene, causing impairment of the peroxisomal β-oxidation process and in consequence, accumulation of very long-chain fatty acids (VLCFA) in blood and tissues. In this study we present serum very long-chain fatty acids levels during clinical course in an X-linked adrenoleukodystrophy patient after haematopoietic stem cell transplantation (HSCT) and on Lorenzo's Oil in a 11 years' period. The patient was diagnosed at the age of 8 months by family screening. The administration of LO was started at 2 years of age. HSCT from a family donor was performed twice. VLCFA serum levels were detected by the GC method. Chimaerism subsequent to HSCT was also analyzed. Increasing very long-chain fatty acids levels correlate with a decreasing chimaerism level after haematopoietic stem cell transplantation. The sequential monitoring of very long-chain fatty acids serum levels is important and useful for assessment of engraftment, graft failure or rejection.
