Non-suppressible viraemia during HIV-1 therapy: a challenge for clinicians.

In individuals receiving antiretroviral therapy (ART), persistent low-level viraemia not attributed to suboptimal ART adherence, detrimental pharmacological interactions, or drug resistance is referred to as non-suppressible viraemia (NSV). This Review presents recent findings in the virological characterisation of NSV, revealing that it consists of one or a few identical populations of plasma viruses without signs of evolution. This finding suggests that NSV originates from virus production by expanded HIV-infected cell clones, reflecting the persistence of the HIV reservoir despite ART. We discuss knowledge gaps regarding the management and the clinical consequences of NSV. The prevalence of NSV remains to be precisely determined and there is very little understanding of its effects on virological failure, HIV transmission, secondary inflammation, morbidity, and mortality. This issue, along with the absence of specific recommendations for the management of NSV in HIV clinical guidelines, underscores the complexities involved in treating individuals with NSV.
