Detailed Description
Autism Spectrum Disorder (ASD) is a clinically and genetically heterogeneous collection of different conditions, sharing socio-communicative deficits, repetitive behaviors, restricted interests, and dysfunctional sensory processing. Currently there are no pharmaceutical compounds effective on core ASD symptoms. Enhanced oxidative stress and mitochondrial dysfunction represent one of the most replicated abnormalities detected both systemically and in the Central Nervous System (CNS) of autistic individuals. Abnormalities in redox parameters are significantly correlated with the severity of autistic behaviors. Although oxidative stress usually represents the consequence and not the primary cause of ASD, reduced ATP production and oxidative damage can seemingly contribute an additional burden to the dysfunction directly produced by ASD-causing genetic or epigenetic defects. Importantly, redox abnormalities have been detected also in young autistic children and are not correlated with age. Therefore, enhanced oxidative stress and mitochondrial dysfunction represent an ASD-related "state-dependent" characteristic present in a consistent number of autistic individuals regardless of their age and of their specific underlying pathogenetic underpinnings. Sustaining mitochondrial function while controlling redox imbalance thus represents a viable "indirect" therapeutic approach, potentially able to ameliorate behavioral and neuropsychological deficits in many autistic individuals.
Coenzyme Q10 (CoQ10, ubiquinone or ubiquinol) is a lipid soluble compound present in the majority of living cells. By increasing energy production and antioxidant capacity, CoQ10 is predicted to limit the damage generated by the neuroinflammation and excitotoxicity well documented in ASD brains, ultimately leading to excessive neuritic pruning and/or cell apoptosis. Administration of Q10 ubiquinol to autistic children, as frequently prescribed to children with mitochondrial disorders, yielded promising results with an extremely low incidence and minor impact of side effects in two open trials and in three RCTs involving numerous other active compounds. In the present RCT, each patient will receive Q10 ubiquinol (50-100 mg b.i.d.) + Vit. E (60 mg/die) and polyvitamin B for 4 months and only Vit. E and B for another 4 months (total duration 8 months) in a double-blind, cross-over design. The focused co-administration of Q10 ubiquinol with only two known antioxidants, vitamin E and a multivitamin B complex, is designed to synergistically boost the increase in energy production and cell protection viewed as deriving primarily from Q10 ubiquinol administration. This study was also designed to overcome two limitations present in previous RCTs evaluating the effects of Q10 Ubiquinone (precursor of Q10 ubiquinol) in ASD children and adults: (a) The administration of a very limited number of active compounds, as compared to cocktails containing many active substances, allows to focus here on the efficacy of Q10 ubiquinol; (b) the administration of Q10 ubiquinol, rather than its precursor Q10 ubiquinone, avoids the potential risk of reduced response due to pharmacokinetic interference with the biotransformation of the precursor into the active compound.
This trial addresses the efficacy of Q10 ubiquinol, paired with Vit. E and B, not only in "idiopathic" ASD, but also in "syndromic" ASD, using Phelan-McDermid syndrome (PMS) as a paradigm. PMS, also known as chromosome 22q13.3 deletion syndrome, represents one of the most studied syndromic forms of ASD. It is characterized by autism in as many as 70-80% of deletion carriers, in addition to early onset severe muscle hypotonia, developmental delay, facial dysmorphisms, absence of spoken language or severe language development disorder. Deletions or mutations of the SHANK3 gene, encoding a synaptic scaffold protein critical to glutamatergic synapse function, are primarily responsible for the syndrome, although larger 22q13.3 deletions encompass additional disease genes.
This study shall include up to 140 patients with idiopathic ASD and 60 patients with PMS. The study design of this RCT was balanced, so that half of the patients with ASD or PMS will receive Q10 ubiquinol during the first 4 months, and the remaining half will receive Q10 ubiquinol during the second 4 months. The purpose of this balancing is to observe not only whether Q10 ubiquinol produces and improvement in primary and secondary measures, but also if this improvement is sustained over time despite Q10 discontinuation or requires continued Q10 administration. In addition to clinical and psychometric parameters, oxidative stress will be measured at baseline and after 4 and 8 months, by drawing 8-10 ml of blood, isolating leukocytes by Ficoll gradient and assessing (a) protein carbonylation levels by oxyblot; (b) the activity of mitochondrial respiratory chain complexes normalized by citrate synthase activity; (c) the expression levels of mitochondrial respiratory chain complexes measured by Western-Blotting.
