Acute retroviral syndrome is associated with lower CD4 + T cell nadir and delayed viral suppression, which are blunted by immediate antiretroviral therapy initiation.

Abstrakt:	Objectives: To describe the prevalence of acute retroviral syndrome (ARS) and associated findings during primary HIV, and explore the relationship of ARS to clinical, virological, and immunological outcomes within a longitudinal screen, retest and treat study that minimized ascertainment bias. Design: We evaluated ARS symptoms and signs among 216 persons with acute and early incident HIV within the Sabes study of timing of antiretroviral therapy (ART) initiation during primary HIV in Peru. Methods: We evaluated patient reported symptoms and signs during primary HIV and used logistic regression and generalized linear models to evaluate associations with CD4 + and CD8 + T cell counts, HIV viral load, and a panel of 23 soluble markers of immune activation. Results: Sixty-one percent of participants had at least one ARS finding and 35% had at least 3. More ARS findings were reported in those enrolled within a month of estimated date of detectable infection (EDDI). Having more ARS signs/symptoms was associated with increased risk of CD4 + cell decrease below 350 cells/ml within the first 24 weeks, failure to suppress HIV viral load, and was most strongly associated with elevated IP-10. Immediate ART blunted effects on symptoms, CD4 + cell count and viral load, as associations were strongest in the arm that started ART after 24 weeks. Detrimental associations of ARS with CD4 + counts, and CD4 + /CD8 + ratio were not maintained at 2 or 4 years. Conclusions: ARS has marked associations with short-term immunologic function and virologic suppression, which were mitigated in participants randomized to initiate ART immediately during primary infection.
