Antagonists in the medical management of opioid use disorders: Historical and existing treatment strategies.

BACKGROUND AND OBJECTIVES: Opioid use disorder (OUD) is a chronic condition with potentially severe health and social consequences. Many who develop moderate to severe OUD will repeatedly seek treatment or interact with medical care via emergency department visits or hospitalizations. Thus, there is an urgent need to develop feasible and effective approaches to help persons with OUD achieve and maintain abstinence from opioids. Treatment that includes one of the three FDA-approved medications is an evidence-based strategy to manage OUD. The purpose of this review is to address practices for managing persons with moderate to severe OUD with a focus on opioid withdrawal and naltrexone-based relapse-prevention treatment. METHODS: Literature available on PubMed was used to review the evolution of treatment strategies from the 1960s onward to manage opioid withdrawal and initiate treatment with naltrexone. RESULTS: Emerging practices for extended-release naltrexone induction include the use of agonist tapers and adjuvant medications. Clinical challenges frequently encountered when initiating this therapy include managing withdrawal and ongoing opioid use during treatment. Clinical factors may inform decisions regarding patient selection and length of naltrexone treatment, such as recent opioid use and patient preferences. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Treatment strategies to manage opioid withdrawal have evolved, but many patients with OUD do not receive medication for the prevention of relapse. Clinical strategies for induction onto extended-release naltrexone are now available and can be safely and effectively implemented in specialty and select primary care settings. (© 2018 The Authors.

Proactive coping and spirituality among patients who left or remained in antiretroviral treatment in St Petersburg, Russian Federation.

Positive Psychology, the study of "positive" factors or strengths and evidence-based interventions to increase them, is a rapidly developing field that is beginning to be applied to HIV care. Proactive coping and spirituality are two positive characteristics that have been examined in multiple chronic serious health conditions. In the present study, lost-to-care (LTCs; did not attend treatment for ≥12 months; n = 120) and engaged-in-care HIV clinic patients (EICs; attended treatment for ≥12 months and adherent with antiretrovirals; n = 120) in Leningrad Oblast, Russian Federation were compared on the Proactive Coping Inventory and View of God Scale. EICs had higher scores in proactive coping [t(229) = 3.69; p = .001] and instrumental [t(232) = 2.17; p = .03] and emotional [t(233) = 2.33; p = .02] support, indicating that they engage in autonomous goal setting and self-regulate their thoughts and behaviors; obtain advice and support from their social network; and cope with emotional distress by turning to others. LTCs had higher scores in avoidance coping [t(236) = -2.31; p = .02]. More EICs were spiritual, religious, or both [ χ(2)(1, N = 239) = 7.49, p = .006]. EICs were more likely to believe in God/Higher Power [χ(2)(1, N = 239 = 8.89, p = .002] and an afterlife [ χ(2)(1, N = 236) = 5.11, p = .024]; have a relationship with God/Higher Power [ χ(2)(1, N = 237) = 12.76, p = .000]; and call on God/Higher Power for help, healing, or protection [ χ(2)(1, N = 239) = 9.61]. EICs had more positive [t(238) = 2.78; p = .006] and less negative [t(236) = -2.38; p = .002] views of God. Similar proportions, but slightly more EICs than LTCs were members of a faith community; members of a12-step group; or attended religious or spiritual services, meetings, or activities. More EICs than LTCs engaged in private spiritual or religious activities, such as prayer or meditation [ χ(2)(1, N = 239) = 9.226, p = .002].

Anhedonia, depression, anxiety, and craving in opiate dependent patients stabilized on oral naltrexone or an extended release naltrexone implant.

BACKGROUND: Naltrexone is a µ-opioid receptor antagonist that blocks opioid effects. Craving, depression, anxiety, and anhedonia are common among opioid dependent individuals and concerns have been raised that naltrexone increases them due to blocking endogenous opioids. Here, we present data that address these concerns. OBJECTIVE: Assess the relationship between affective responses and naltrexone treatment. METHODS: Opioid dependent patients (N = 306) were enrolled in a three cell (102ss/cell) randomized, double blind, double dummy, placebo-controlled 6-month trial comparing extended release implantable naltrexone with oral naltrexone and placebo (oral and implant). Monthly assessments of affective responses used a Visual Analog Scale for opioid craving, the Beck Depression Inventory, Spielberger Anxiety Test, and the Ferguson and Chapman Anhedonia Scales. Between-group outcomes were analyzed using mixed model analysis of variance (Mixed ANOVA) and repeated measures and the Tukey test for those who remained and treatment and did not relapse, and between the last measure before dropout with the same measure for those remaining in treatment. RESULTS: Depression, anxiety, and anhedonia were elevated at baseline but reduced to normal within the first 1-2 months for patients who remained in treatment and did not relapse. Other than a slight increase in two anxiety measures at week two, there were no significant between-group differences prior to treatment dropout. CONCLUSION: These data do not support concerns that naltrexone treatment of opioid dependence increases craving, depression, anxiety or anhedonia.

Depression, substance use, viral load, and CD4+ count among patients who continued or left antiretroviral therapy for HIV in St. Petersburg, Russian Federation.

Antiretroviral therapy (ART) became more widely available in the Russian Federation in 2006 when the Global Fund made a contribution to purchase ART with a mandate to increase numbers of patients receiving it. Funds were distributed to AIDS Centers and selected hospitals, and numbers quickly increased. Though ART is highly effective for adherent patients, dropout has been a problem; thus understanding characteristics of patients who remain on ART vs. those who leave treatment may provide information to facilitate engagement. We retrospectively assessed depression, hopelessness, substance use, viral load, and CD4+ counts of 120 patients who dropped out of ART for ≥12 months (Lost-to-Care, LTCs) and 120 who continued for ≥12 months (Engaged-in-Care, EICs). As expected, LTCs had higher viral loads and depression, lower CD4+ counts, more alcohol, heroin, and injection drug use in the past 30 days. A binary logistic regression with Center for Epidemiologic Studies Depression score, Beck Hopelessness score, whether drugs/alcohol had ever prevented them from taking ART, and past 30 days' alcohol use [χ(2)(4) = 64.27, p = .0.000] correctly classified 74.5% of participants as LTC or EIC, suggesting that integrated treatment for substance use, psychiatric, and HIV could reduce dropout and improve outcomes.

Substance use disorder and its effects on outcomes in men with advanced-stage prostate cancer.

BACKGROUND: Substance use disorder in patients with cancer has implications for outcomes. The objective of this study was to analyze the effects of the type and timing of substance use on outcomes in elderly Medicare recipients with advanced prostate cancer. METHODS: This was an observational cohort study using Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data from 2000 to 2009. Among men who were diagnosed with advanced prostate cancer between 2001 and 2004, we identified those who had a claim for substance use disorder in the year before cancer diagnosis, 1 year after cancer diagnosis, and an additional 4 years after diagnosis. The outcomes investigated were use of health services, costs, and mortality. RESULTS: The prevalence of substance use disorder was 10.6%. The category drug psychoses and related had greater odds of inpatient hospitalizations (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.9-2.8), outpatient hospital visits (OR, 2.6; 95% CI, 1.9-3.6), and emergency room visits (OR, 1.7; 95% CI, 1.2-2.4). Substance use disorder in the follow-up phase was associated with greater odds of inpatient hospitalizations (OR, 2.0; 95% CI, 1.8-2.2), outpatient hospital visits (OR, 2.0; 95% CI, 1.7-2.4), and emergency room visits (OR, 1.7; 95% CI, 1.5-2.1). Compared with men who did not have substance use disorder, those in the category drug psychoses and related had 70% higher costs, and those who had substance use disorder during the follow-up phase had 60% higher costs. The hazard of all-cause mortality was highest for patients in the drug psychoses and related category (hazard ratio, 1.3; 95% CI, 1.1-1.7) and the substance use disorder in treatment phase category (hazard ratio, 1.5; 95% CI, 1.3-1.7). CONCLUSIONS: The intersection of advanced prostate cancer and substance use disorder may adversely affect outcomes. Incorporating substance use screening and treatments into prostate cancer care guidelines and coordination of care is desirable.

Using the AUDIT-PC to predict alcohol withdrawal in hospitalized patients.

BACKGROUND: Alcohol withdrawal syndrome (AWS) occurs when alcohol-dependent individuals abruptly reduce or stop drinking. Hospitalized alcohol-dependent patients are at risk. Hospitals need a validated screening tool to assess withdrawal risk, but no validated tools are currently available. OBJECTIVE: To examine the admission Alcohol Use Disorders Identification Test-(Piccinelli) Consumption (AUDIT-PC) ability to predict the subsequent development of AWS among hospitalized medical-surgical patients admitted to a non-intensive care setting. DESIGN: Retrospective case­control study of patients discharged from the hospital with a diagnosis of AWS. All patients with AWS were classified as presenting with AWS or developing AWS later during admission. Patients admitted to an intensive care setting and those missing AUDIT-PC scores were excluded from analysis. A hierarchical (by hospital unit) logistic regression was performed and receiver-operating characteristics were examined on those developing AWS after admission and randomly selected controls. Because those diagnosing AWS were not blinded to the AUDIT-PC scores, a sensitivity analysis was performed. PARTICIPANTS: The study cohort included all patients age ≥18 years admitted to any medical or surgical units in a single health care system from 6 October 2009 to 7 October 2010. KEY RESULTS: After exclusions, 414 patients were identified with AWS. The 223 (53.9 %) who developed AWS after admission were compared to 466 randomly selected controls without AWS. An AUDIT-PC score ≥4 at admission provides 91.0 % sensitivity and 89.7 % specificity (AUC=0.95; 95 % CI, 0.94­0.97) for AWS, and maximizes the correct classification while resulting in 17 false positives for every true positive identified. Performance remained excellent on sensitivity analysis (AUC=0.92; 95 % CI, 0.90­0.93). Increasing AUDIT-PC scores were associated with an increased risk of AWS (OR=1.68, 95 % CI 1.55­1.82, p<0.001). CONCLUSIONS: The admission AUDIT-PC score is an excellent discriminator of AWS and could be an important component of future clinical prediction rules. Calibration and further validation on a large prospectivecohort is indicated.

Lost-to-care and engaged-in-care HIV patients in Leningrad Oblast, Russian Federation: barriers and facilitators to medical visit retention.

Sixty-nine percent of the 1.5 million Eastern Europeans and Central Asians with HIV live in the Russian Federation. Antiretroviral therapy (ART) is effective but cannot help those who leave treatment. Focus groups with patients who dropped out of ART for ≥12 months (lost-to-care, LTCs, n = 21) or continued for ≥12 months (engaged-in-care; EICs; n = 24) were conducted in St. Petersburg. Structural barriers included stigma/discrimination and problems with providers and accessing treatment. Individual barriers included employment and caring for dependents, inaccurate beliefs about ART (LTC only), side-effects, substance use (LTCs, present; EICs, past), and depression. Desire to live, social support, and spirituality were facilitators for both; EICs also identified positive thinking and experiences with ART and healthcare/professionals. Interventions to facilitate retention and adherence are discussed.

Antagonist models for treating persons with substance use disorders.

This paper provides an overview on the status of antagonist models for treating patients with substance use disorders. It begins with an overview describing the ambivalence about stopping or not stopping substance use and how antagonist approaches, combined with psychosocial treatment, are aimed to address it. It then goes on to review data on disulfiram and acamprosate treatment of alcohol dependence and naltrexone treatment of opioid and alcohol dependence. The superior results achieved by extended release formulations are emphasized. The mixed findings on naltrexone treatment for amphetamine dependence are presented and the chapter ends with a brief review of vaccine development for treatment of substance use disorders. Overall conclusions are that the strongest treatment effects are with extended release naltrexone with opioid dependence. Disulfiram treatment of alcohol dependence also has strong effects but is not widely used due to low levels of patient acceptance and concerns about its potential for serious adverse events. Less robust but clinically meaningful effects are seen with naltrexone or acamprosate treatment of alcohol dependence. Vaccines are a very interesting and promising new development but many challenges and hurdles must be overcome before they are ready for clinical use.

Progress in addiction treatment: from one-size-fits-all to medications and treatment matching.

This paper briefly reviews the development of treatment for substance use disorders over the last 100 years from the perspective of the author, who has participated in treatment outcome studies since the mid-1970s. It includes some personal events that contributed to the author's involvement in addiction treatment and research, and describes the gradual evolution of an approach that began with a focus on detoxification and psychosocial treatment to one that involves blending psychosocial treatments with use of Food and Drug Administration (FDA)-approved medications and adding treatments for psychiatric and medical disorders when necessary based on patient assessments. It ends with comments on the gap between what is known and the degree to which existing knowledge is applied, and how the Affordable Care Act holds promise for bridging that gap.

Effects of Opioid Withdrawal on Psychobiology in People Living with HIV.

OBJECTIVE: Many persons with opioid use disorders (OUDs) have HIV disease and experience clinically significant stress after they enroll in abstinence-based treatment and undergo medically assisted withdrawal. We examined whether opioid withdrawal affects virologic control, inflammatory markers, cognition, and mood in persons with an OUD and HIV, and explored whether measures of withdrawal stress, such as activation of the HPA axis, contribute to alterations in immune function, cognition, and mood. METHOD AND PARTICIPANTS: Study participants were 53 persons with HIV who were admitted for OUD treatment at the City Addiction Hospital in Saint Petersburg, Russian Federation. Participants were examined at admission, at the anticipated peak of withdrawal 3 to 7 days after the last day of a clonidine-based withdrawal process lasting 7 to 14 days, and 3 to 4 weeks after completing withdrawal. At these times, participants received medical exams and were evaluated for symptoms of withdrawal, as well as cognition and mood. Viral load, plasma cortisol, DHEA sulfate ester (DHEA-S), interleukin-6 (IL-6), and soluble CD14 (sCD14) were determined. Multivariable models examined the relationships between markers of HPA activation and the other parameters over time. RESULTS: HPA activation as indexed by cortisol/DHEA-S ratio increased during withdrawal, as did markers of immune activation, IL-6 and sCD14. There were no significant associations between viral load and indicators of HPA activation. In longitudinal analyses, higher cortisol/DHEA sulfate was related to worse cognition overall, and more mood disturbance. Increase in IL-6 was associated with worse cognitive performance on a learning task. There were no significant associations with sCD14. CONCLUSIONS: Worsening of cognition and measures of mood disturbance during withdrawal were associated with activation of the HPA axis and some measures of inflammation. Whether repeated episodes of opioid withdrawal have a cumulative impact on long-term HIV outcomes and neurocognition is a topic for further investigation.

Factors contributing to dropping out from and returning to HIV treatment in an inner city primary care HIV clinic in the United States.

Although advances in pharmacotherapy have enabled people living with HIV/AIDS to live longer, fuller lives, some leave medical care, resulting in sub-optimal treatment and increased health risk to themselves and others. Forty-one patients who dropped out of an urban, publically funded primary care HIV clinic were contacted and encouraged by outreach staff to return. Participants were interviewed within two weeks of returning, and themes associated with dropping out and returning were elicited and content analyzed. Dropping out was associated with drug/alcohol use, unstable housing/homelessness, psychiatric disorders, incarceration, problems with HIV medications, inability to accept the diagnosis, relocation, stigma, problems with the clinic, and forgetfulness. Returning was associated with health concerns, substance abuse treatment/recovery, stable housing, incarceration/release, positive feelings about the clinic, spirituality, and assistance from family/relocation. Because a large number of patients reported substance abuse, depression, and past suicide attempts. Clinic staff should assess substance use, depression, and suicidal ideation at each primary care visit and encourage patients to obtain substance abuse treatment and mental health care. Future interventions could include providing SBIRT and/or onsite mental health and substance abuse treatment, all of which may boost retention.

Determinants of health-related quality of life among individuals with opioid use disorder, recently released from incarceration.

BACKGROUND\OBJECTIVES: Concomitant with low rates of pharmacotherapy for incarcerated individuals with OUD, there is a high rate of opioid overdose following re-entry into the community. Our research objective was to develop a better understanding of the factors that influence health-related quality-of-life (HRQoL) among this population during the high-risk transition period from incarceration to community. Few studies have assessed health-related quality-of-life (HRQoL) among individuals with OUD who are involved with the criminal-legal system, let alone over the period directly surrounding release from incarceration. METHODS: Secondary longitudinal analysis of data from a clinical trial where participants were randomized 1:1 to pre-release extended-release naltrexone (XR-NTX) + referral to community XR-NTX, vs. referral only. We conducted individual, multivariable regressions of EQ-5D domains (mobility, pain/discomfort, anxiety/depression; usual activities and self-care were excluded due to insufficient variation in scores), and the overall preference/utility score. HRQoL data were subset to timepoints immediately before release (baseline) and 12 weeks post-release; treatment groups were collapsed across condition. Multiple imputation by chained equations was conducted to handle missing 3-month data in the dependent variables and covariates, ad hoc. RESULTS: Greater severity in the psychiatric composite score was associated with substantially lower HRQoL, across all measures, following release from incarceration. Greater severity in the medical composite score was associated with lower pain/discomfort-related HRQoL. CONCLUSIONS: Our findings highlight the importance of ensuring individuals with OUD are linked not only to MOUD, but also treatment for their comorbid conditions upon release from incarceration.

Compensation effects on clinical trial data collection in opioid-dependent young adults.

BACKGROUND: Attrition in studies of substance use disorder treatment is problematic, potentially introducing bias into data analysis. OBJECTIVES: This study aimed to determine the effect of participant compensation amounts on rates of missing data and observed rates of drug use. METHODS: We performed a secondary analysis of a clinical trial of buprenorphine/naloxone among 152 treatment-seeking opioid-dependent subjects aged 15-21 during participation in a randomized trial. Subjects were randomized to a 2-week detoxification with buprenorphine/naloxone (DETOX; N = 78) or 12 weeks buprenorphine/naloxone (BUP; N = 74). Participants were compensated $5 for weekly urine drug screens and self-reported drug use information and $75 for more extensive assessments at weeks 4, 8, and 12. RESULTS: Though BUP assignment decreased the likelihood of missing data, there were significantly less missing data at 4, 8, and 12 weeks than other weeks, and the effect of compensation on the probability of urine screens being positive was more pronounced in DETOX subjects. CONCLUSION: These findings suggest that variations in the amount of compensation for completing assessments can differentially affect outcome measurements, depending on treatment group assignment. SCIENTIFIC SIGNIFICANCE: Adequate financial compensation may minimize bias when treatment condition is associated with differential dropout and may be a cost-effective way to reduce attrition. Moreover, active users may be more likely than non-active users to drop out if compensation is inadequate, especially in control groups or in groups who are not receiving active treatment.

Opioid detoxification and naltrexone induction strategies: recommendations for clinical practice.

BACKGROUND: Opioid dependence is a significant public health problem associated with high risk for relapse if treatment is not ongoing. While maintenance on opioid agonists (i.e., methadone, buprenorphine) often produces favorable outcomes, detoxification followed by treatment with the µ-opioid receptor antagonist naltrexone may offer a potentially useful alternative to agonist maintenance for some patients. METHOD: Treatment approaches for making this transition are described here based on a literature review and solicitation of opinions from several expert clinicians and scientists regarding patient selection, level of care, and detoxification strategies. CONCLUSION: Among the current detoxification regimens, the available clinical and scientific data suggest that the best approach may be using an initial 2-4 mg dose of buprenorphine combined with clonidine, other ancillary medications, and progressively increasing doses of oral naltrexone over 3-5 days up to the target dose of naltrexone. However, more research is needed to empirically validate the best approach for making this transition.

The science and practice of medication-assisted treatments for opioid dependence.

This paper briefly reviews the evolution of opioid addiction treatment from humanitarian to scientific and evidence-based, the evidence bases supporting major medication-assisted treatments and adjunctive psychosocial techniques, as well as challenges faced by clinicians and treatment providers seeking to provide those treatments. Attitudes, politics, policy, and financial issues are discussed.

Cost-effectiveness of extended-release injectable naltrexone among incarcerated persons with opioid use disorder before release from prison versus after release.

INTRODUCTION: Opioid use disorder (OUD) is highly prevalent among incarcerated populations, and the risk of fatal overdose following release from prison is substantial. Despite efficacy, few correctional facilities provide evidence-based addiction treatment. Extended-release injectable naltrexone (XR-NTX) administered prior to release from incarceration may improve health and economic outcomes. METHODS: We conducted an economic evaluation alongside a randomized controlled trial testing the effectiveness of XR-NTX before release from prison (n = 38) vs. XR-NTX referral after release (n = 48) of incarcerated participants with OUD, both groups continuing treatment at a community addiction treatment center. The incremental cost-effectiveness ratio (ICER) assessed the cost-effectiveness of XR-NTX before release compared to referral after release for three stakeholder perspectives at 12- and 24-week periods: state policymaker, health care sector, and societal. Effectiveness measures included quality-adjusted life-years (QALYs) and abstinent years from opioids. In addition, we categorized resources as OUD-related and non-OUD-related medical care, state transfer payments, and other societal costs (productivity, criminal justice resources, etc.). RESULTS: Results showed an association between XR-NTX and greater OUD-related costs and total costs from the state policymaker perspective. QALYs gained were positive but statistically insignificant between arms; however, results showed XR-NTX had an estimated 15.5 more days of opioid abstinence over 24 weeks and statistically significant at a 95 % confidence level based on the distribution of bootstrapped samples. We found that estimated ICERs to be > $500,000 per QALY for all stakeholder perspectives. For the abstinent-year effectiveness measure, we found XR-NTX before release to be cost-effective at a 95 % confidence level for willingness-to-pay values >$49,000 per abstinent-year, across all perspectives. CONCLUSIONS: XR-NTX administered to persons who are incarcerated with OUD before release may provide value for stakeholders and bridge a well-known treatment gap for this vulnerable population. Lower than expected participant engagement and missing data limit our results, and study outcomes may be sensitive to methods that address missing data if replicated.

Identifying Clinically Relevant Drug-Drug Interactions With Methadone and Buprenorphine: A Translational Approach to Signal Detection.

Methadone and buprenorphine have pharmacologic properties that are concerning for a high risk of drug-drug interactions (DDIs). We performed high-throughput screening for clinically relevant DDIs with methadone or buprenorphine by combining pharmacoepidemiologic and pharmacokinetic approaches. We conducted pharmacoepidemiologic screening via a series of self-controlled case series studies (SCCS) in Optum claims data from 2000 to 2019. We included persons 18 years or older who experienced an outcome of interest during target drug treatment. Exposures were all overlapping medications (i.e., the candidate precipitants) during target drug treatment. Outcomes were opioid overdose, non-overdose adverse effects, and cardiac arrest. We used conditional Poisson regression to calculate rate ratios, accounting for multiple comparisons with semi-Bayes shrinkage. We explored the impact of key study design choices in analyses that varied the exposure definitions of the target drugs and the candidate precipitant drugs. Pharmacokinetic screening was conducted by incorporating published data on CYP enzyme metabolism into an equation-based static model. In SCCS analysis, 1,432 events were included from 248,069 new users of methadone or buprenorphine. In the primary analysis, statistically significant DDIs included gabapentinoids with either methadone or buprenorphine; baclofen with methadone; and benzodiazepines with methadone. In sensitivity analysis, additional statistically significant DDIs included methocarbamol, quetiapine, or simvastatin with methadone. Pharmacokinetic screening identified two moderate-to-strong potential DDIs (clonidine and fluconazole with buprenorphine). The combination of clonidine and buprenorphine was also associated with a significantly increased risk of opioid overdose in pharmacoepidemiologic screening. These DDI signals may be the most important targets for future confirmation studies.

NIDA's Clinical Trials Network: an opportunity for HIV research in community substance abuse treatment programs.

BACKGROUND/OBJECTIVES: HIV continues to be a significant problem among substance users and their sexual partners in the United States. The National Drug Abuse Treatment Clinical Trials Network (CTN) offers a national platform for effectiveness trials of HIV interventions in community substance abuse treatment programs. This article presents the HIV activities of the CTN during its first 10 years. RESULTS: While emphasizing CTN HIV protocols, this article reviews the (1) HIV context for this work; (2) the collaborative process among providers, researchers, and National Institute on Drug Abuse CTN staff, on which CTN HIV work was based; (3) results of CTN HIV protocols and HIV secondary analyses in CTN non-HIV protocols; and (4) implications for future HIV intervention effectiveness research in community substance abuse treatment programs. CONCLUSION/SIGNIFICANCE: While the feasibility of engaging frontline providers in this research is highlighted, the limitations of small to medium effect sizes and weak adoption and sustainability in everyday practice are also discussed.

Burden of Chronic Conditions Among Persons with HIV/AIDS and Psychiatric Comorbidity.

BACKGROUND: Improved survivorship among persons living with HIV translates into a higher risk of medical comorbidities. OBJECTIVES: We assessed the association between the intersection of physical (HIV) and mental health (psychiatric) conditions and intermediate outcomes. METHODS: This was a cross-sectional study of the Medical Expenditure Panel Survey (MEPS)- Household Component between 1996 and 2016. We created four groups for persons aged ≥18: (1) HIV + psychiatric comorbidity, (2) HIV, (3) psychiatric comorbidity, and (4) no-HIV/no-psychiatric comorbidity. We compared the burden of medical comorbidities (metabolic disorders, cardiovascular disease, cancers, infectious diseases, pain, and substance use) among groups using chisquare tests. We used logistic regression to determine the association between group status and medical comorbidity. RESULTS: Of 218,133,630 (weighted) persons aged ≥18, 0.18% were HIV-positive. Forty-three percent of the HIV group and 19% of the no-HIV group had psychiatric comorbidities. Half of the HIV+ psychiatric disorder group had at least one medical comorbidity. Compared to the no- HIV/no-psychiatric comorbidity group, the HIV + psychiatric comorbidity group had the highest odds of medical comorbidity (OR= 3.69, 95% CI = 2.99, 4.52). CONCLUSION: Persons presenting with HIV + psychiatric comorbidity had higher odds of medical comorbidities of pain, cancer, cardiovascular disease, substance use, metabolic disorders and infectious diseases, beyond that experienced by persons with HIV infection or psychiatric disorders, independently. Future research will focus on the mediating effects of social determinants and biological factors on outcomes such as the quality of life, cost and mortality. This will facilitate a shift away from the single-disease framework and compress morbidity of the aging cohort of HIV-infected persons.

Extended release injectable naltrexone before vs. after release: A randomized trial of opioid addicted persons who are in prison.

BACKGROUND: Usual treatment for persons with opioid use disorders who are in prison is detoxification with referral to treatment after release but failure to engage in treatment and relapse is common. Starting medication treatment before release might improve outcomes. OBJECTIVES: Determine if administering extended-release injectable naltrexone (XR-NTX) before release (BR) from prison results in less relapse within the first three months after release than when offered by referral after release (AR). METHODS: The study randomized 1:1 persons who had an OUD, expressed interest in XR-NTX, and met study admission criteria to receive XR-NTX BR or at a local program AR, with continued medication and counseling available at that program. RESULTS: Four-hundred and two persons expressed interest in the study, 222 consented, and the study randomized 146. Uncertainty about release dates resulted in a time lag between randomization and final disposition during which 60 of the randomized patients were sentenced to other facilities, withdrew consent, or became otherwise unavailable for study treatment, leaving 86 for outcome analyses (38, BR; 48 AR). Missed follow-up appointments on the remaining 86 led to development of a phone-based questionnaire to determine presence/absence of relapse. Using it to supplement other data, we were able to confirm relapse or nonrelapse for 63 of the 86 (73%). All BR and a third of the AR patients received their first XR-NTX dose, however dropout was high and nonrelapse by month three was not significantly different between BR (39.5%) and AR (25%) (Chisq (2) = 3.23, p = 0.20). CONCLUSIONS: BR patients were much more likely to receive medication and its extended relapse and overdose protection effects in the first weeks after release. Dropout was high and the study detected no significant difference in relapse by month 3; however, the less-than-planned number of patients and missing data make this finding inconclusive.
