Chronic High Risk Prescription Opioid Use Among Persons With HIV

Trajectories of Opioid Misuse and Opioid Use Disorder Among Adults With Chronic Pain and HIV: An Observational Study

OBJECTIVES

In a longitudinal cohort of patients with HIV and chronic pain, we sought to (1) identify trajectories of opioid misuse and opioid use disorder (OUD) symptoms, and to (2) determine whether prescription opioid dose was associated with symptom trajectories.

METHODS

We leveraged an existing 12-month longitudinal observational study, Project PIMENTO, of persons living with HIV and chronic pain who received care at a hospital system in the Bronx, New York. A quota sampling strategy was used to ensure variability of prescribed opioid use in the recruited sample. Research interviews occurred quarterly and assessed opioid behaviors and criteria for OUD. To describe symptom trajectories, we conducted 2 separate longitudinal latent class analyses to group participants into (1) opioid misuse and (2) OUD trajectories. Finally, we used multinomial logistic regression models to examine the relationship between baseline prescription opioid dose and symptom trajectories.

RESULTS

Of 148 total participants, at baseline 63 (42.6%) had an active opioid prescription, 69 (46.6%) met the criteria for current opioid misuse, and 44 (29.7%) met the criteria for current OUD. We found 3 opioid misuse and 3 OUD symptom trajectories, none of which showed worsened symptoms over time. In addition, we found that higher prescription opioid dose at baseline was associated with a greater OUD symptom trajectory.

CONCLUSIONS

Opioid misuse and OUD were common but stable or decreasing over time. Although these results are reassuring, our findings also support prior studies that high-dose opioid therapy is associated with greater OUD symptoms.

Opioid misuse among people with HIV: results from the National Survey on Drug Use and Health (NSDUH) 2015-2019

Aim: Pain is a major challenge in the management of HIV/AIDS. This research analyzed the prevalence of substance use and opioid misuse among people with HIV (PWH) and those without (PWoH) in the USA. Methods: Using data from the 2015-2019 National Survey on Drug Use and Health, the study assessed misuse of pain relievers and opioids in 279,025 individuals. Results: PWH were about 1.88-times more likely to misuse pain relievers and 1.85-times to misuse opioids than PWoH, with a notable rise in hydrocodone and tramadol misuse. Conclusion: The data highlights an imperative for interventions targeting substance misuse among PWH, addressing the complex nexus of HIV, chronic pain and opioid use.

Astrocytes: Role in pathogenesis and effect of commonly misused drugs in the HIV infected brain

The roles of astrocytes as reservoirs and producers of a subset of viral proteins in the HIV infected brain have been studied extensively as a key to understanding HIV-associated neurocognitive disorders (HAND). However, their comprehensive role in the context of intersecting substance use and neurocircuitry of the reward pathway and HAND has yet to be fully explained. Use of methamphetamines, cocaine, or opioids in the context of HIV infection have been shown to lead to a faster progression of HAND. Glutamatergic, dopaminergic, and GABAergic systems are implicated in the development of HAND-induced cognitive impairments. A thorough review of scientific literature exploring the variety of mechanisms in which these drugs exert their effects on the HIV brain and astrocytes has revealed marked areas of convergence in overexcitation leading to increased drug-seeking behavior, inflammation, apoptosis, and irreversible neurotoxicity. The present review investigates astrocytes, the neural pathways, and mechanisms of drug disruption that ultimately play a larger holistic role in terms of HIV progression and drug use. There are opportunities for future research, therapeutic intervention, and preventive strategies to diminish HAND in the subset population of patients with HIV and substance use disorder.

Endogenous opiates and behavior: 2021

This paper is the forty-fourth consecutive installment of the annual anthological review of research concerning the endogenous opioid system, summarizing articles published during 2021 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides and receptors as well as effects of opioid/opiate agonizts and antagonists. The review is subdivided into the following specific topics: molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors (1), the roles of these opioid peptides and receptors in pain and analgesia in animals (2) and humans (3), opioid-sensitive and opioid-insensitive effects of nonopioid analgesics (4), opioid peptide and receptor involvement in tolerance and dependence (5), stress and social status (6), learning and memory (7), eating and drinking (8), drug abuse and alcohol (9), sexual activity and hormones, pregnancy, development and endocrinology (10), mental illness and mood (11), seizures and neurologic disorders (12), electrical-related activity and neurophysiology (13), general activity and locomotion (14), gastrointestinal, renal and hepatic functions (15), cardiovascular responses (16), respiration and thermoregulation (17), and immunological responses (18).

Sleep Disturbances and Chronic Pain in People with HIV: Implications for HIV-Associated Neurocognitive Disorders

Purpose of Review

Antiretroviral therapy has significantly reduced morbidity and mortality in people with HIV. Despite being virally suppressed, sleep disturbances, chronic pain, and neurocognitive impairments persist which can negatively impact quality of life for people with HIV. This article presents relevant literature related to sleep disturbances and chronic pain in people with HIV. The potential impact of these comorbidities on cognition is discussed with implications for managing HIV-associated neurocognitive disorder (HAND).

Recent Findings

People with HIV and chronic pain report greater insomnia and depressive symptoms compared to those without chronic pain. The neurotoxic effects of HIV itself and sleep and chronic pain induced inflammation can contribute to poorer cognitive outcomes.

Summary

Sleep disturbances and chronic pain are prevalent conditions in people with HIV that may perpetuate the development and exacerbation of HAND. Sleep and pain interventions may preserve cognitive function and improve quality of life for people aging with HIV.

Escalated (Dependent) Oxycodone Self-Administration Is Associated with Cognitive Impairment and Transcriptional Evidence of Neurodegeneration in Human Immunodeficiency Virus (HIV) Transgenic Rats

Substance use disorder is associated with accelerated disease progression in people with human immunodeficiency virus (HIV; PWH). Problem opioid use, including high-dose opioid therapy, prescription drug misuse, and opioid abuse, is high and increasing in the PWH population. Oxycodone is a broadly prescribed opioid in both the general population and PWH. Here, we allowed HIV transgenic (Tg) rats and wildtype (WT) littermates to intravenously self-administer oxycodone under short-access (ShA) conditions, which led to moderate, stable, "recreational"-like levels of drug intake, or under long-access (LgA) conditions, which led to escalated (dependent) drug intake. HIV Tg rats with histories of oxycodone self-administration under LgA conditions exhibited significant impairment in memory performance in the novel object recognition (NOR) paradigm. RNA-sequencing expression profiling of the medial prefrontal cortex (mPFC) in HIV Tg rats that self-administered oxycodone under ShA conditions exhibited greater transcriptional evidence of inflammation than WT rats that self-administered oxycodone under the same conditions. HIV Tg rats that self-administered oxycodone under LgA conditions exhibited transcriptional evidence of an increase in neuronal injury and neurodegeneration compared with WT rats under the same conditions. Gene expression analysis indicated that glucocorticoid-dependent adaptations contributed to the gene expression effects of oxycodone self-administration. Overall, the present results indicate that a history of opioid intake promotes neuroinflammation and glucocorticoid dysregulation, and excessive opioid intake is associated with neurotoxicity and cognitive impairment in HIV Tg rats.
