Brief Summary:
The purpose of this study is to assess the phenotypic candidates symptoms, in patients with crack/cocaine addiction, in terms of clinical comorbidities, dimensions of personality, and neuropsychological evaluations apt to be associated with genetic and genotypic characterisations, notably on the polymorphisms of the genes coding or regulating dopaminergic, norepinephrine and serotoninergic systems.

Condition or disease Intervention/treatment Phase
Dependence, Cocaine Genetic: Collect 10 ml of Saliva for DNA extraction Not Applicable

Detailed Description:
Genetic studies show an association between drug addiction and the dopaminergic system and its modulators. Nonetheless, results are contradictory, partially due to the heterogeneity of the phenotype addiction. Placed on the trafficking route of cocaine, and homogeneously populated, Martinique is of particular interest for the study of the vulnerability of the crack/cocaine addiction. In a precedent study, supported by a grant MILDT / INSERM 2000, on 155 men dependent to crack/cocaine and characterised with three clinical dimensions -sensation seeking, impulsivity and childhood ADHD- we found an association between each dimension and polymorphisms of DRD2 and DRD4 genes.

Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Case Control Study on Contribution to the Analysis of the Phenotypic Heterogeneity in Crack/Cocaine Addiction
Study Start Date : December 2009
Estimated Primary Completion Date : December 2012
Estimated Study Completion Date : December 2012

Intervention Details:
  • Genetic: Collect 10 ml of Saliva for DNA extraction
    After signed written informed consent, all patients and controls have clinical and neuropsychological evaluations (DIGS, WURS, BROWN, BIS, SSS and IGT) for phenotypic diagnosis and collection of saliva for DNA extraction and genotyping diagnosis.


Primary Outcome Measures :
  1. The specific measure that will be related to core objectives of the study is to constitute a sample collection from saliva. [ Time Frame: The saliva will be collect at the end of the first visit ]
