Deksametazon w celu ukierunkowania na stres i mechanizmy układu odpornościowego leżące u podstaw głodu alkoholowego

28 września 2026 zaktualizowane przez: Helen Fox, Stony Brook University

Deksametazon w celu zwalczania stresu i zmian układu odpornościowego podczas wczesnej abstynencji u osób z zaburzeniami związanymi z używaniem alkoholu (AUD)

This is a double-blind, placebo-controlled, proof of concept laboratory study to recruit N=70 (35 Males / 35 Females) non-treatment seeking, heavy drinkers with alcohol use disorder (AUD). It is hypothesized that randomization to 1.5mgs dexamethasone versus placebo will decrease alcohol craving during stress by decreasing basal cortisol, increasing anti-inflammatory cytokine levels and potentially normalizing the immune response to stress.

The 8-item Alcohol Urges Questionnaire (AUQ) will be used to measure alcohol craving. There are 8 items, each with a Likert scale response from 1 to 7 (1: Strongly Disagree, 7: Strongly Agree). Total possible score of 56. The higher the score the higher the alcohol craving
