Abstract

Introduction: Changes in the composition of gut microflora have been associated with an increase in chronic diseases. Indican urinary concentration is one of the most common and easily assessable markers of intestinal dysbiosis. Little information is available on intestinal dysbiosis in Parkinson's disease (PD). We decided to investigate indican urinary concentrations in a cohort of PD patients. Methods: A case-control study including PD patients (N=68) on treatment with levodopa (PD) or on no pharmacological treatment (De Novo, DPD; N = 34) and an age and gender-matched healthy control group (CTR; N = 50). Main confounders, such as nutritional habits and constipation diagnosed according to Rome III criteria, were also investigated. Results: Indican urinary concentrations were significantly higher in PD and DPD than in CTR (P
