Since ART cannot clear the HIV reservoir that is established soon after infection, children living with HIV (CLWH) are forced to rely on therapy for their lives and suffer from long-term drug-related complications. Pediatric HIV infection, like adult infection, is associated with gut microbial dysbiosis, loss of gut epithelial integrity, bacterial translocation, CD4 + T cell depletion, systemic immune activation, and viral reservoir establishment. However, unlike in adults, HIV that is vertically acquired by infants interacts with a gut microbiome that is continuously evolving while concomitantly shaping the infant's immune ontogeny. Therefore, to determine whether there may be interventions that target the HIV reservoir through microbiome-directed approaches, understanding the complex tripartite interactions between the transmitted HIV, the maturing gut microbiome, and the developing immune system during early life is crucial. Importantly, early life is the time when the gut microbiome of an individual is highly dynamic, and this temporal development of the gut microbiome plays a crucial role in educating the maturing immune system of a child. Therefore, manipulation of the gut microbiome of CLWH to a phenotype that can reduce HIV persistence by fostering an antiviral immune system might be an opportune strategy to achieve ART-free viral suppression in CLWH.
