Summary
Integrase strand transfer inhibitors (INSTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) impact HIV patient metabolomes differently. INSTIs show a more favorable cardiovascular disease risk profile compared to NNRTIs.
Area of Science:
- HIV/AIDS research
- Metabolomics and lipidomics
- Cardiovascular disease risk
Background:
- Combination antiretroviral therapy (cART) is standard for people living with HIV (PLHIV).
- Integrase strand transfer inhibitors (INSTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) are key cART components.
- Different cART regimens may influence non-AIDS comorbidities, including cardiovascular disease.
Purpose of the Study:
- To compare the metabolome and lipidome profiles of patients on INSTI-based versus NNRTI-based cART regimens.
- To investigate potential differences in cardiovascular disease risk associated with these drug classes.
Main Methods:
- Utilized untargeted metabolomic analysis (mass spectrometry) on plasma samples from the 2000HIV study (n=1646).
- Employed targeted lipoprotein and lipid analysis (nuclear magnetic resonance spectroscopy).
- Identified perturbed metabolic pathways using MetaboAnalyst software.
Main Results:
- Metabolome homogeneity observed within INSTI and NNRTI groups, but significant differences between groups.
- INSTI users exhibited altered levels of metabolites related to lipids, organic acids, and organoheterocyclic compounds.
- INSTI use was linked to a less favorable lipid profile than nevirapine but more favorable than doravirine, with INSTIs showing a better cardiovascular risk profile overall.
Conclusions:
- INSTI and NNRTI regimens induce distinct metabolic and lipidomic changes in PLHIV.
- NNRTIs demonstrate more heterogeneous cardiometabolic effects compared to INSTIs.
- INSTI-based cART may offer a more favorable cardiovascular disease risk profile than some NNRTI-based regimens.

Retrovirus Life Cycles
45.9K
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...

Sexually Transmitted Infections
303
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
