Prolonged HIV Remission in Children After Early ART Initiation: Hope for a Cure?

The 2024 Conference on Retroviruses and Opportunistic Infections (CROI) in Denver offered a glimmer of hope in the fight against HIV.

A presentation highlighted the case of four children who remained HIV-undetectable for over a year after suspending antiretroviral therapy (ART).

These children, all infected with HIV before birth, were part of a closely monitored clinical trial funded by the National Institutes of Health (NIH).

This finding reignites the scientific quest for an HIV cure, particularly for children infected perinatally (during pregnancy, childbirth, or breastfeeding). While ART can effectively suppress the virus, achieving a true cure – complete eradication of HIV from the body – remains elusive. However, this new research suggests that early ART initiation, coupled with a child’s developing immune system, might offer a unique opportunity for achieving long-term viral control even after stopping treatment.

Understanding HIV Latency and the Challenges of a Cure

HIV is a complex retrovirus that integrates its genetic material into the DNA of infected host cells. This ability to create a viral reservoir within these cells, known as latency, poses a significant challenge for achieving a cure. Even with ART effectively suppressing viral replication, these hidden reservoirs can act as a source of rebounding virus when treatment is interrupted [1].

Multiple research avenues are exploring strategies to overcome this hurdle. The “kick and kill” approach aims to activate latent reservoirs, making infected cells susceptible to the immune system’s attacks [2]. Another strategy involves blocking mechanisms that allow HIV to establish latency in the first place [3].

Early ART Initiation and Potential for Post-Treatment Control

The recent CROI presentation focused on a specific group: children who received ART extremely early in life, within 48 hours of birth. This approach, known as early ART initiation (eART), has shown promise in limiting the establishment of the viral reservoir. Studies suggest that eART might lead to a more robust immune response in developing children compared to adults infected later in life [4].

The case of the four children who remained virus-free after stopping ART aligns with this theory. Their early exposure to treatment might have prevented the formation of a large viral reservoir, allowing their immune systems to effectively control residual low-level viral replication even after ART cessation.

Research Nuances and the Path Forward

It’s crucial to emphasize that this is a small-scale study with limited data points. Further research with a larger cohort is necessary to confirm these findings and assess the generalizability of these results. Additionally, the long-term effects of stopping ART in children require careful monitoring and evaluation.

However, this research offers valuable insights. Studies published in the prestigious journal Nature Medicine have explored the impact of eART on viral reservoirs in children. One such study, published in 2020, demonstrated a significant reduction in the size of the viral reservoir in children who received eART compared to those who started treatment later [5]. This bolsters the hypothesis that early intervention might play a crucial role in limiting HIV reservoirs and potentially achieving post-treatment control.

Sexuality and Long-Term Management

While the possibility of prolonged HIV remission after early ART initiation is encouraging, it’s important to acknowledge the complexities involved in managing HIV throughout an individual’s life. As these children reach adolescence and young adulthood, considerations around sexual health and HIV transmission prevention become paramount.

Research published in the Journal of the American Medical Association (JAMA) in 2023 highlights the importance of comprehensive sexual health education for youth living with HIV [6]. This education should address topics such as safe sex practices, HIV transmission risks, and the impact of treatment adherence on viral suppression.

Furthermore, ongoing monitoring and support are crucial for these children as they navigate their sexual health journey. Regular viral load testing and adherence counseling are essential to ensure continued viral suppression and prevent potential transmission risks.


The CROI presentation on the four children experiencing prolonged HIV remission after stopping ART offers a beacon of hope in the pursuit of an HIV cure. Early ART initiation, particularly in children, might hold the key to achieving long-term viral control and potentially even a functional cure.

However, much work remains to be done. Larger-scale studies and long-term monitoring are critical to validate these findings and ensure the safety and well-being of children undergoing such interventions. Additionally, addressing the sexual health needs of these individuals as they mature is crucial for their holistic well-being.

This research paves the way for further investigation and development of strategies to combat HIV, offering a potentially brighter future for children infected perinatally.
