Insights

Integrase strand transfer inhibitor (INSTI) use, including dolutegravir (DTG) and raltegravir (RAL), has increased among children with HIV in Latin America and the Caribbean. Further research is needed to understand the clinical impact of these HIV treatments in pediatric populations.

Area of Science:

  • Pediatric infectious diseases
  • HIV/AIDS treatment
  • Pharmacovigilance in children

Background:

  • Limited data exist on integrase strand transfer inhibitor (INSTI) use in pediatric populations.
  • Assessing dolutegravir (DTG) and raltegravir (RAL) use and outcomes in children with HIV in Latin America and the Caribbean is crucial.

Purpose of the Study:

  • To evaluate trends and factors associated with INSTI initiation (DTG/RAL) in children with HIV.
  • To compare viral and treatment outcomes based on INSTI use in pediatric HIV care.

Main Methods:

  • Analysis of data from pediatric cohorts in Brazil, Haiti, and Honduras (2013-2022).
  • Utilized multivariable logistic and Cox regression models for ART-naïve and ART-experienced children, respectively.
  • Log-rank tests were used to compare outcomes between INSTI users and non-users in ART-naïve children.

Main Results:

  • INSTI initiation, particularly DTG, increased significantly among ART-naïve children from 2016 to 2022.
  • Older age and more recent calendar years were associated with higher DTG initiation rates in ART-naïve children.
  • No significant difference in virologic suppression was observed between DTG users and non-users, but DTG users had longer first-regimen duration.

Conclusions:

  • INSTI use has demonstrably increased among children with HIV in parts of Latin America and the Caribbean.
  • The clinical impact of INSTI regimens in pediatric HIV management requires further investigation.

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 retrovirus to...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Retroviruses02:33

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
Subviral Agents01:29

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
