Objective: Our purpose was to determine whether the use of catechol-O-methyltransferase-inhibitors (ICOMT) can reduce the risk of developing levodopa (LD)-induced neuropathy in Parkinson's disease (PD) patients. Methods: A multicentre study of 197 PD patients was performed. 144 were exposed to LD for more than three years (LELD group); 53 simultaneously assumed Entacapone for at least eighteen months (LELD_ICOMT group). Results: The prevalence of neuropathy in LELD patients was 19.4% whereas it was 5.7% in LELD_ICOMT group with a significant difference (p = 0.025). In LELD_ICOMT cohort the daily LD dose and serum VB12 levels were significantly higher (p
