[Clinical and therapeutic implications of quantifying HIV reservoirs]

Archiving HIV in its long half-life target cells is responsible for building what are called its reservoirs. The quantification of total HIV DNA in blood mononuclear cells, which probably represents only an approximation of all anatomical and cellular reservoirs, has, however, been the subject of numerous studies which showed strong correlations with other methods of quantification of reservoirs, with the natural history of the infection, its virological, immunological and clinical evolution under treatment, as well as its predictive value of the success of specific strategies (i.e. therapeutic de-escalation or interruption). This technique is easily accessible routinely and, although there are still no quantitative thresholds validated for decision-making, it may be useful to use it to clarify certain clinical or virological situations or to reinforce specific therapeutic choices (especially during therapeutic de-escalation).
