Abstract

Current therapies for the Lesch-Nyhan Syndrome (OMIM: 300322) are off-label and experimental, often leading to inconsistent outcomes. We here report the effects of an intrathecal baclofen therapy, carried out at the Scientific Institute Eugenio Medea (Lecco, Italy), on three patients who no longer received benefit from previous therapies. This treatment, as expected, ameliorated the motor symptoms and, unexpectedly, it also improved behavioural components. This result may involve a functional interaction between baclofen and dopamine, complemented by an anxiolytic effect. Our observations provide the rationale for the use of intrathecal baclofen administration in the therapy of the Lesch-Nyhan Syndrome.
