Popis: | Background: Long-term benefits of combination antiretroviral therapy (cART) initiation during primary HIV-1 infection are debated. Methods: The evolution of plasma HIV-RNA (432 measurements) and cell-associated HIV-DNA (325 measurements) after cessation of cART (median exposure 18 months) was described for 33 participants from the Zurich Primary HIV Infection Study using linear regression and compared with 545 measurements from 79 untreated controls with clinically diagnosed primary HIV infection, respectively a known date for seroconversion. Results: On average, early treated individuals were followed for 37 months (median) after cART cessation; controls had 34 months of pre-cART follow-up. HIV-RNA levels one year after cART interruption were 20.8 log10 copies/mL [95% confidence interval 21.2;20.4] lower in early treated patients compared with controls, but this difference was no longer statistically significant by year three of follow-up (20.3 [20.9; 0.3]). Mean HIV-DNA levels rebounded from 2 log10 copies [1.8; 2.3] on cART to a stable plateau of 2.7 log10 copies [2.5; 3.0] attained 1 year after therapy stop, which was not significantly different from cross-sectional measurements of 9 untreated members of the control group (2.8 log10 copies [2.5; 3.1]). Conclusions: The rebound dynamics of viral markers after therapy cessation suggest that early cART may indeed limit reservoir size of latently infected cells, but that much of the initial benefits are only transient. Owing to the non-randomized study design the observed treatment effects must be interpreted with caution. |
