Confounding may account for the apparent improved infant outcomes after prenatal exposure to buprenorphine versus methadone. We used Massachusetts Medicaid Analytic eXtract (MAX) data to identify a cohort of opioid dependent mother-infant pairs (2006-2011) supplemented with confounder data from an external Boston cohort (2015-2016). Associations between prenatal buprenorphine versus methadone exposure and infant outcomes in the MAX Cohort were adjusted for measured MAX confounders, and unmeasured confounders with bias analysis using External Cohort data...

Opioid addiction in pregnancy is a growing concern that has recently received a lot of attention. When comparing recommended opioid agonist therapies, many currently published studies guiding practice may be impacted by unmeasured confounding by indication. Populations of women who receive methadone are generally different from those treated with buprenorphine. Women treated with methadone frequently have more severe and uncontrolled addiction compared with buprenorphine treated patients; however, these factors are typically unmeasured or unavailable in large observational data sets...

BACKGROUND: Extended-release naltrexone (XR-NTX), an opioid antagonist, and sublingual buprenorphine-naloxone (BUP-NX), a partial opioid agonist, are pharmacologically and conceptually distinct interventions to prevent opioid relapse. We aimed to estimate the difference in opioid relapse-free survival between XR-NTX and BUP-NX. METHODS: We initiated this 24 week, open-label, randomised controlled, comparative effectiveness trial at eight US community-based inpatient services and followed up participants as outpatients...

BACKGROUND AND OBJECTIVES: Previous research has been inconclusive about whether opioid-dependent patients with psychiatric comorbidities have shorter treatment retention and higher relapse rates. This study aims to evaluate the impact of mental health comorbidities on adherence to buprenorphine using a large, national health insurance claims data base. METHODS: We used MarketScan® data from 2012 to 2014 to perform this analysis. Inclusion criteria included all patients with an opioid use disorder-related ICD-9 code who had been prescribed buprenorphine (n = 2947)...

BACKGROUND AND OBJECTIVES: Opioid use disorder among young adults is rising sharply with an increase in morbidity and mortality. This study examined differences in treatment response to a fixed dose of buprenorphine-naloxone between heroin (HU) and prescriptions opioids (POU) users. METHODS: Eighty opioid dependent young adults (M = 22 years) were treated with buprenorphine-naloxone 16-4 mg/day for 8 weeks. Differences between HU (N = 17) and POU (N = 63) on changes in weekly opioid use, opioid craving, withdrawal, and depression symptoms were analyzed with mixed-effects regression models...

BACKGROUND AND OBJECTIVES: Little is known about the health of children exposed to opioid pharmacotherapies in utero. This study aims to examine the health of children from birth to 5 years of age, who were exposed to methadone, buprenorphine, or naltrexone with non-exposed children. METHODS: Children were identified by linking the treatment records of women treated with one of the three opioid pharmacotherapies with midwife notifications. Live-born children exposed to methadone (n = 198), buprenorphine (n = 122), naltrexone (n = 67) in utero, and neonates not prenatally exposed to opioids (n = 387) born between 2001 and 2011 in Western Australia were included in the study...

BACKGROUND: Overdoses due to non-medical use of prescription opioids and other opiates have become the leading cause of accidental deaths in the USA. Buprenorphine and extended-release naltrexone are key evidence-based pharmacotherapies available to addiction treatment providers to address opioid use disorder (OUD) and prevent overdose deaths. Treatment organizations' efforts to provide these pharmacotherapies have, however, been stymied by limited success in recruiting providers (physicians, nurse practitioners, and physician assistants) to prescribe these medications...

BACKGROUND: Among persons with opioid use disorder (OUD), neuropsychological dysfunction is associated with depression, and better neuropsychological function is associated with opioid abstinence. However, it is unknown whether depressive symptomatology or adherence to opiate agonist treatment are associated with neuropsychological change over time. METHODS: We recruited 20 buprenorphine/naloxone-treated adults with OUD (M Age = 45.2 years [SD = 8.1]; 25% female) to complete baseline and 6 month visits containing a neuropsychological test battery and self-reported measures of depressive symptomatology and medication adherence...

The prevalence of urine tampering within office-based opioid treatment (OBOT) is not currently known. This study was a cross-sectional analysis of an OBOT practice in New York City that experienced both a change in provider and a change in electronic medical record software. At that time, every patient in the practice received a urine drug test for "quantitative buprenorphine metabolites." METHODS: Outcomes of the first three urine drug tests were tabulated and analyzed with specific attention to the frequency of buprenorphine-positive (bup+), norbuprenorphine-negative (norbup-) samples, a pattern consistent with urine tampering...

A quantitative trait locus (QTL) on proximal chromosome (Chr) 10 accounts for > 50% of the genetic variance in methamphetamine (MA) intake in mice selectively bred for high (MAHDR) and low (MALDR) voluntary MA drinking. The µ-opioid receptor (MOP-r) gene, Oprm1, resides at the proximal end of Chr 10, and buprenorphine reduces MA intake in MAHDR mice. However, this drug has only partial agonist effects at MOP-r. We investigated the impact of a full MOP-r agonist, morphine, on MA intake and saccharin intake, measured MOP-r density and affinity in several brain regions of the MA drinking lines and their C57BL/6J (B6) and DBA/2J (D2) progenitor strains, and measured MA intake in two congenic strains of mice to verify the QTL and reduce the QTL interval...

This study investigated a 51-year-old married man with a history of heroin dependence who underwent methadone maintenance treatment for 7 years. He received traditional Chinese medicine (TCM)-facilitated treatments and switched from methadone to buprenorphine/naloxone. Strong anxiety symptoms were observed during the initial stage; therefore, we prescribed a combination of Chaihu-Shugan-San, Zhi Bai Di Huang and Chin-Gin-Kuan-Ming decoction as the major herbal synergic regimen to relieve the symptoms of opioid withdrawal, anxiety and insomnia...

Background: Postoperative secondary hyperalgesia arises from central sensitization due to pain pathways facilitation and/or acute opioid exposure. The latter is also known as opioid-induced hyperalgesia (OIH). Remifentanil, a potent μ-opioid agonist, reportedly induces postoperative hyperalgesia and increases postoperative pain scores and opioid consumption. The pathophysiology underlying secondary hyperalgesia involves N-methyl-D-aspartate (NMDA)-mediated pain pathways. In this study, we investigated whether perioperatively infusing low-dose buprenorphine, an opioid with anti-NMDA activity, in patients receiving remifentanil infusion prevents postoperative secondary hyperalgesia...

Macrophages (Mf) are a versatile group of phagocytic cells responsible for fulfilling a variety of immune functions, most notably for mounting the initial anti-microbial response and for the clearance of cellular debris and apoptotic bodies. The key processes for fulfilling these functions include the production of reactive oxygen intermediates (ROIs) and nitric oxide (NO). Mf also express a variety of receptors, including opioid, serotonin, and norepinephrine receptors, and thus can react to various substances...

BACKGROUND: Our objective was to estimate the association between methadone and neonatal abstinence syndrome compared with buprenorphine using a probabilistic bias analysis to account for unmeasured confounding by severity of addiction. METHODS: We used a cohort of live-born infants exposed in utero to methadone or buprenorphine for maternal opioid maintenance therapy at Magee-Womens Hospital in Pittsburgh, PA from 2013-2015 (n=716). We determined exposure and outcome status using pharmacy billing claims...
