Behavioural Addictions Occurring During a Dopaminergic Treatment Prescribe Under Parkinson's Disease: Study of the Psychopathological, Neurological, Pharmacokinetic and Genetic Profiles (PARKADD)

14. Februar 2018 aktualisiert von: Nantes University Hospital

Behavioural Addictions Occurring During a Dopaminergic Treatment Prescribe Under Parkinson's Disease: Study of the Psychopathological, Neurological, Pharmacokinetic and Genetic Profiles.

This study is composed of a main study and an ancillary one. The objective of the main study is to define, on the psychopathological, neurological, pharmacokinetic and genetic plan, the predictive factors for developing a behavioural addiction (BA) secondarily to the dopaminergic treatment, associated or not to a dopamine dysregulation syndrome (DDS), in patients with Parkinson's disease.

3 particular profiles of patients will be established:

  • BA- : no secondary behavioural addiction
  • BA+/DDS-: secondary behavioural addiction, without dopamine dysregulation syndrome
  • BA+/DDS+: secondary behavioural addiction, with dopamine dysregulation syndrome

We wish in particular:

  • To differentiate, among the BA+ subjects, those for who is a DDS from those for who we can evoke a side effect of the dopaminergic treatment
  • To demonstrate that the BA+/DDS- subjects present pharmacokinetic particularities causing the occurrence of the BA.
  • To clarify the possible relationship between the dosage and the pharmacodynamics of the treatment (especially that of pramipexole) in one hand, and the developing of BA in the other hand.
  • Demonstrate that the subjects BA + / DDS- are individually genetic vulnerability (related to the dopamine system), originally from the occurrence of the BA.

This study has several levels of evaluation, we chose describe the methodology of the study in 3 axis : Psychopathology axis, Neurological axis and pharmacokinetic axis.

The pharmacokinetic aspects will be studied only on a part of the sample, in an ancillary study centered on the pharmacokinetic of the pramipexole (in its immediate release form).

Detaillierte Beschreibung

This is a monocentric study with a recruitment period comprised between October 2012 and April 2016. The recruitment occurs during the consultations in the service of neurology. If the subjects are eligible, the study is proposed to them, and an evaluation is fixed in the next days. This evaluation consists in an individual face-to-face interview based on standardized and semi-structured questionnaires, during approximately one and a half hour. It's focused on the different characteristics of Parkinson's disease, and on psychiatric and addictive co morbidities. The evaluation is completed by a set of self-administered questionnaires focused on impulsivity and Attention Deficit Hyperactivity Disorder (ADHD).

For the 80 patients participated to the ancillary study only, a blood sample will be realized when the patient will arrived, just before the intake of his treatment (to obtain the residual plasmatic concentration). A second sample will be realized at a different time for each patient, to cover the entirety of the kinetic between 2 intakes of pramipexole (immediate release form) via the entire sample. The second blood sample will be realized four hours after the first one at the most. After this second sample, the patient will have completed his participation to the study.

Secondly, monitoring including a self-questionnaire booklet and a saliva sample will be offered to all patients who completed the initial visit.

Was misst die Studie?

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Psychopathological axis : score of sensation seeking (S Score) of the impulsivity questionnaire "UPPS"
This choice is founded on the fact that patients suffering of DDS are described as being impulsive, misusing their anti-parkinsonism treatment in the purpose of stimulate themselves, suggesting they have a high level of sensation and novelty seeking.
Pharmacological axis : Area under the curve of the pramipexole concentration
Area under the curve of the pramipexole concentration in function of the time between 2 intakes of pramipexole.
Neurological axis : Unified Parkinson's Disease Rating Scale (UPDRS) III score
UPDRS III score, with axial under-score in ON and OFF DOPA (Parkinson's disease severity)
Genetic axis : distribution of allele frequencies and genotypic
Distribution of allele frequencies and genotypic
