简要总结
A global and integrative treatment of opioid-use disorders (OUD) with opiate maintenance therapy (OMT) and psychosocial interventions is recommended by all current guidelines. Treatment of OUD aim at prevents risks and consequences of opioid use (death by overdose, contamination with infectious diseases, mental and physical degradation, social exclusion and decrease of quality of life). OMT are approved since more than 20 years for OUD and a large number of patients have been treated. Nevertheless, identification of prognosis factors associated with good outcome is still limited. OMT duration, high dosages of OMT and patient good consistency have been identified as good prognosis factors but other individual factors could be involved and explain why OMT isn't as effective for all patients. The investigators assume that social environment, other addictive behaviors, psychiatric comorbidities, personality disorders and pharmacogenetics parameters might be of interest. Association between phenotype/ genotype, safety of OMT and therapeutic outcome will be especially assessed. For voluntary patients specific tools for risk reduction will be implemented (screening of infectious diseases with blood tests and fibrosis with fibroscan). Thus, the aim of TOPAZE study is to highlight prognosis factors for good outcome in the treatment of OUD moderate to severe at 12 months follow-up. Three main axes will be considered: clinical, pharmacological and pharmacogenetics.
详细描述
All patients with moderate or severe OUD diagnosis (according to Diagnostic and Statistical Manual Diploma in Social Medicine 5) who initiate OMT in addictionology department of Nantes hospital or in addiction care and prevention centers of Nantes could be included. Data will be collected during 3 visits.
During the first visit (inclusion), clinical interview, electrocardiogram, urinary and blood tests (pharmacokinetics and pharmacogenetics analysis) will be provided. Infectious disease screening and fibroscan could be also provided as the patient wishes. Inclusion visit will also correspond to initiation of OMT.
At 6 months follow-up (second visit) clinical interview, electrocardiogram, urinary and blood tests (pharmacokinetics and pharmacogenetics analysis) will be provided.
At 12 months follow-up (final visit) clinical interview, electrocardiogram and urinary test will be provided.

结局指标
主要结局
Clinical, pharmacokinetics and pharmacogenetics characteristics associated with good outcome of patients treated with OMT.
时间窗: 12 months
Good outcome is defined as early remission of opioid-related disorder according to Diagnostic and Statistical Manual of Mental Disorders Fifth version (none of the diagnostic criteria except craving within last three months) and no initiation or worsening of other addictive behavior (substance use disorders or gambling disorder according to Diagnostic and Statistical Manual of Mental Disorders Fifth version within last 12 months).
