Evaluation of dynamic thiol/disulphide homeostasis as a novel indicator of oxidative stress in maple syrup urine disease patients under treatment.
Maple syrup urine disease (MSUD) is a metabolic disorder that is caused by deficiency of branched-chain α-keto acid dehydrogenase complex. Although accumulation of toxic metabolites is associated with neurotoxicity, mechanisms underlying brain damage remain unclear. Aim of this study is to evaluate thiol/disulphide homeostasis as a novel indicator of oxidative stress in MSUD patients under treatment. ⋯ In recent studies, it was claimed that oxidative stress could be responsible from neurotoxicity even in treated patients. Here, dynamic thiol/disulfide homeostasis status showed that providing good metabolic control in MSUD patients prevent oxidative stress. Under regular follow-up and good compliance with diet, additional antioxidant therapies would possibly not be necessary.
