Insights

Opioid use impacts HIV infection stages and immune responses. Research suggests potential reductions in HIV reservoirs with opioid use disorder treatments, guiding future HIV cure studies.

Area of Science:

  • Immunology
  • Virology
  • Pharmacology

Background:

  • Opioid engagement with Mu opioid receptors influences HIV life cycle stages.
  • The impact of opioid use on HIV latency and viral reservoirs is not fully understood.
  • Increased immune activation in opioid users was hypothesized to enlarge HIV reservoirs, but this is not supported by current data.

Purpose of the Study:

  • To review experimental data linking opioid use to HIV modulation.
  • To explore the scientific basis for differential changes in immune activation and HIV reservoirs with various opioid use disorder medications.
  • To guide future HIV cure-directed research in individuals with HIV and opioid use disorder.

Main Methods:

  • Review of experimental data on opioid use and HIV.
  • Analysis of scientific premises for immune activation and HIV reservoir changes.
  • Consideration of Mu opioid receptor engagement and ART-mediated immune reconstitution.

Main Results:

  • Opioid use affects HIV replication, immune activation, and microbial dysbiosis.
  • Evidence suggests opioid use may lead to lower latent HIV burden.
  • Differential effects on immune activation and HIV reservoirs are expected with different medications for opioid use disorder.

Conclusions:

  • Understanding opioid receptor interactions and ART-mediated immune reconstitution is crucial.
  • Opioid use can impact immune reconstitution outcomes even with viral suppression.
  • Further research is needed to optimize HIV cure strategies for individuals with co-occurring HIV and opioid use disorder.

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Opioid Receptors: Overview01:22

Opioid Receptors: Overview

Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Opioid Analgesics: Morphine and Other Natural Cogeners

Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
