Is there a rationale for a 4-drug based antiretroviral therapy?
Since 1996 – the birthdate of modern HAART – there has been a strong commitment to reach both therapeutic efficacy and avoidance of drug resistance in case of virologic failure. The paradigm that was set back then was to treat HIV with a triple-drug combination. Nowadays, there are several examples when this paradigm has been surpassed, both with a two-drug regimen or a four-drug regimen. During 2017, two articles must be mentioned. The first one deals with a four-drug regimen during the hyper-acute phase of HIV infection, which eventually led to an analytical treatment interruption , whereas the second one describes the efficacy of a four-drug regimen for HIV-infected subjects with a baseline HIV-RNA ≥500,000 copies/mL . Both papers are not concluding the debate but surely shed more light on this matter.
