INTRODUCTION: Anderson-Fabry disease (AFD) is an X-linked lysosomal storage
disorder caused by mutations of GLA gene leading to reduced ?-galactosidase
activity and resulting in a progressive accumulation of globotriaosylceramide
(Gb3) and its deacylated derivative, globotriaosyl-sphingosine (Lyso-Gb3). Plasma
Lyso-Gb3 levels serve as a disease severity and treatment monitoring marker
during enzyme replacement therapy (ERT). METHODS: Adult patients with AFD who had
yearly pulmonary function tests between 1999 and 2015 were eligible for this
observational study. Primary outcome measures were the change in z-score of
forced expiratory volume in the first second (FEV(1)) and FEV(1)/FVC over time.
Plasma Lyso-Gb3 levels and the age of ERT initiation were investigated for their
association with lung function decline. RESULTS: Fifty-three patients (42% male,
median (range) age at diagnosis of AFD 34 (6-61) years in men, 34 (13-67) in
women) were included. The greatest decrease of FEV(1)/FVC z-scores was observed
in Classic men (-0.048 per year, 95%?CI -0.081 to -0.014), compared with the
Later-Onset men (+0.013,95% CI -0.055 to 0.082), Classic women (-0.008, 95% CI
-0.035 to +0.020) and Later-Onset women (-0.013, 95% CI -0.084 to +0.058).
Cigarette smoking (P=0.022) and late ERT initiation (P=0.041) were independently
associated with faster FEV(1) decline. FEV(1)/FVC z-score decrease was
significantly reduced after initiation of ERT initiation (-0.045 compared with
-0.015, P=0.014). Furthermore, there was a trend towards a relevant influence of
Lyso-Gb3 (P=0.098) on airflow limitation with age. CONCLUSION: Early ERT
initiation seems to preserve pulmonary function. Plasma Lyso-Gb3 is maybe a
useful predictor for airflow limitation. Classic men need a closer monitoring of
the lung function.
