Deksametasoni kohdistaa stressiin ja alkoholinhimoon taustalla oleviin immuunijärjestelmän mekanismeihin

maanantai 28. syyskuuta 2026 päivittänyt: Helen Fox, Stony Brook University

Deksametasoni kohdistaa stressiin ja immuunijärjestelmän muutoksiin varhaisen raittiuden aikana henkilöillä, joilla on alkoholinkäyttöhäiriö (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.
