Brief Summary
A higher prevalence of Helicobacter pylori infection rate has been demonstrated among PD patients compared to controls. As H. pylori infection is known to interfere with levodopa absorption, we embarked on this is a study to understand the effects of Helicobacter pylori infection eradication among a selected Malaysian population with Parkinsons disease, in relation to levodopa effectiveness and motor improvements. The study hypotheses are:
- 1.H. pylori eradication improves L-dopa 'onset' time and prolongs the L-dopa 'on-time' duration.
- 2.PD patients with H. pylori infection show clinical improvement in motor disability and quality of life after eradication therapy of H. pylori, assessed using UPDRS-III / PDQ39 questionnaires.

Outcome Measures
Primary Outcomes (2)
1. H. pylori eradication improves L-dopa 'onset' time and prolongs the L-dopa 'on-time' duration.
This was measured by asking the patient to determine the time taken to experience on from the time of ingestion of levodopa and to determine the duration of time that they are ON, while receiving levodopa. The patients are asked to keep a diary if possible. If not, the patients are asked during their visits, baseline visit, visit 1, visit 2 and visit 3
3months
Improvement in L-dopa 'onset' time and L-dopa 'on-time' duration following H.pylori eradication
Patients are followed up every 4 weeks, for 12 weeks ( 3 visits). The levodopa onset time is calculated based on the time taken to achieve on following levodopa ingestion, while the ON-time duration is the time the patient remains on following levodopa ingestion. Patients are asked to keep a diary, if possible.
3 months post eradication
Secondary Outcomes (1)
Improvement in motor disability after eradication therapy of H. pylori, assessed using UPDRS-III , and improvement in quality of life using PDQ39
3 months post eradication
Study Arms (1)
Eradication therapy
EXPERIMENTALThe patients who were positive for H.pylori infection are entered into an eradication therapy protocol which includes oral esomeprazole 40mg daily, oral clarithromycin 500mg bd and oral amoxicillin 1000mg bd for 14 days.
Interventions
Patients who were positive for H.pylori infection received an eradication therapy consisting of oral esomeprazole 40 md daily, oral clarithromycin 500mg bd and oral amoxicillin 1000mg bd for 14 days.
Patients who are positive on urea breath test are given eradication therapy for 14 days, Eradication therapy includes esomeprazole 40mg daily, clarithromycin 500mg bd, amoxicillin 1g bd
Eligibility Criteria
You may qualify if:
- Diagnosis of idiopathic Parkinson's disease (PD) by a neurologist
- Age more than 18 years
- Written informed consent given either by the patient or next of kin
- Patient on L-DOPA therapy
You may not qualify if:
- Patients with a diagnosis of secondary parkinsonism, and Parkinson's plus syndrome
