Longitudinal study of impact of medication for opioid use disorder on Hamilton Depression Rating Scale.

Abstract

OBJECTIVE\nThis study aimed to evaluate the longitudinal treatment effect on depression measured by Hamilton Depression Rating Scale (HAM-D) score in a randomized clinical trial for the treatment of opioid use disorder (OUD).\n\n\nMETHODS\nWe conducted a secondary data analysis of data from the National Institute on Drug Abuse s Clinical Trials Network Protocol-0051. Patients with OUD (N=570) were randomized to receive buprenorphine/naloxone (BUP-NX, n=287) or extended-release naltrexone injection (XR-NTX, n=283). The HAM-D score was completed at baseline and follow-up visit up to 36 weeks. A linear mixed model analysis was performed for log transformed HAM-D score and the generalized linear mixed model analysis was conducted for depression status.\n\n\nRESULTS\nCompared with BUP-NX, subjects randomized to XR-NTX had higher HAM-D scores at weeks 1 and 3 (p<0.05). There were significant interactions between treatment and visit on HAM-D score and depression status during the first four weeks of treatments in individuals without lifetime major depressive disorder (MDD). Past year cocaine use was associated with HAM-D score and depression status just in individuals without MDD, whereas past year cannabis use was associated with HAM-D score and depression status just in individuals with MDD. Past year amphetamine use was associated with HAM-D score just in individuals without MDD, however, lifetime anxiety was associated with HAM-D scores regardless of MDD.\n\n\nCONCLUSION\nWhen prescribing XR-NTX, particularly in the first month of treatment, it is essential to monitor for depressive symptoms. Screening for depression and multiple substance uses may help clinicians identify appropriate treatment.
