Intrajejunal Levodopa Versus Conventional Therapy in Parkinson Disease:  Motor and Nonmotor Effects

National Parkinson Foundation Centre of Excellence, King's College and Institute of Psychiatry, London, UK, et al.

Abstract

ABSTRACT: Seventeen patients with advanced Parkinson disease (PD) were treated with intrajejunal L-dopa infusion (IJL) and compared with a matched group of 9 patients (termed comparator [C]) not given IJL because of funding restriction by primary care trusts (PCTs) in the UK, although considered to be clinically eligible for IJL. Assessments were baseline and follow-up (6 months) with Hoehn and Yahr staging, unified PD rating scale (UPDRS-III and UPDRS-IV), Parkinson disease questionnaire (PDQ-8, quality of life [QoL]) and nonmotor symptom scale (NMSS).Baseline characteristics were comparable between the groups. The IJL-treated group showed highly significant improvements in UPDRS-III (P = 0.005), UPDRS-IV (P = 0.0004), total NMSS score (P = 0.004), and QoL (P = 0.01), whereas the C group showed no change in these parameters. A large effect size of IJL was seen in treated patients for UPDRS-III (1.13), UPDRS-IV (1.52), NMSS score (0.82), and QoL (1.12), whereas continuing conventional treatment registered no effect in C.This study confirms the robust effect of IJL on motor and, in particular, nonmotor symptoms and QoL in advanced PD as described in open-label studies but additionally points to the need for such treatment in those denied this therapy because of centrally dictated funding policies leading to inequalities in health care.
