Microbiota Modification for the Treatment of Motor Complication of Parkinson´s Disease

January 25, 2021 updated by: José Fidel Baizabal-Carvallo, Torre Médica Santé

Targeting Gut Microbiota for Motor Complications in Parkinson´s Disease

In recent years, abnormalities in gut microbiota have been identified in patients with Parkinson´s disease having a possible role in motor manifestations. Among 80 patients with PD, we selected 14 with LID and motor fluctuations with limited response to pharmacological therapy to receive treatment with sodium phosphate enema, oral rifaximin and polyethylene glycol to improve motor complications.

Description

Inclusion Criteria:

- patients aged 18-years old or older with moderate to severe dyskinesia and/or motor fluctuations with incomplete or poor response to adjustments in time and dose of levodopa and other anti-parkinsonian agents such as entacapone, rasagiline, dopamine receptor agonists and amantadine in 1-2 months prior to enrollment; defined by a Movement Disorders Society Unified Parkinson´s Disease Rating Scale (MDS-UPDRS) part IV score equal or higher than 8 following pharmacological adjustments.

Exclusion Criteria:

  • patients with chronic renal failure, decompensated heart failure, colonic abnormalities precluding the use of evacuating enema, known allergies to prescribed medications to reduce microbiota load and patients who declined to participate in the study.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Microbiota modification
Drug: sodium phosphate enema, oral rifaximin and polyethylene glycol
Patients were hospitalized for 4-5 hours to receive two saline colon enemas with sodium phosphate Fleet®, 2 to 3 hours apart, appropriate hydration was provided during the procedure. If signs of fecal impaction were observed, the stools were removed manually prior to the first enema. Patients were discharged with oral treatment consistent with rifaximin 200 mg three times a day for 7 days and polyethylene glycol-3350, 17 gr per day in water for 10 days, but it was continued if necessary. Importantly, no modifications in time and dose of dopaminergic therapy or anti-dyskinetic medication (i.e. amantadine) were done at baseline or during the study
