Are Epigenetic Biomarkers an Indicator of the Severity of Addiction in Active Opiate Abusers? A Pilot Study
Abstract
Study rationale Opioid use disorder (OUD) is a chronic and severe condition, defined by problematic opioid use, which results from interactions among sociological factors, psychiatric symptoms and life experiences, altogether determining OUD severity.
Recently, behavioral epigenetics has emerged as a possible strategy to help identify molecular mechanisms that may explain how these various interactions result in dysregulations affecting gene expression, brain function, and, ultimately, emotional regulation.
Here the investigators propose a pilot study as a first step towards a larger multidisciplinary project whose goal will be to characterize simultaneously major psychiatric and social factors in individuals with OUD, across a wide range of disease severity. In the present pilot study, the investigators propose to first characterize technical feasibility of the molecular investigations proposed in these 2 projects.
OUD severity The severity of OUD is well defined in the DSM-5 (2013), with 3 categories, from mild to severe, on the basis of the number of dimensional criteria met by patients (among 11 criteria). These criteria relate to the following main aspects: tolerance, the need to increase the amount of drugs to avoid withdrawal; psychic and physic withdrawal in case of substance discontinuation; social and interpersonal consequences of drug use; biological and psychic consequences of use; and craving, the irrepressible need to consume1. Here, the investigators postulate…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 11 participants or records.
