ClinConnect Summary

The factors that influence HIV disease progression are not well understood. While larger amounts of circulating virus (high 'viral loads') predict future adverse clinical events, many of the clinical factors responsible for high viral loads and disease progression remain unknown. Certain clinical events and defined interventions are associated with increases in plasma viral RNA concentrations. One of these clinical interventions is immunization; immunization with several vaccines have been shown to increase plasma HIV RNA concentrations. Even though vaccination can lead to transient increas...
