Background

Men who have sex with men (MSM) with acute human immunodeficiency virus (HIV) infection (AHI) are a key source of new infections. To curb transmission, we implemented a strategy for rapid AHI diagnosis and immediate initiation of combination antiretroviral therapy (cART) in Amsterdam MSM. We assessed its effectiveness in diagnosing AHI and decreasing the time to viral suppression.

Methods

We included 63 278 HIV testing visits in 2008–2017, during which 1013 MSM were diagnosed. Standard of care (SOC) included HIV diagnosis confirmation in &lt; 1 week and cART initiation in &lt; 1 month. The AHI strategy comprised same-visit diagnosis confirmation and immediate cART. Time from diagnosis to viral suppression was assessed for 3 cART initiation periods: (1) 2008–2011: cART initiation if CD4 &lt; 500 cells/μL (SOC); (2) January 2012–July 2015: cART initiation if CD4 &lt; 500 cells/μL, or if AHI or early HIV infection (SOC); and (3a) August 2015–June 2017: universal cART initiation (SOC) or (3b) August 2015–June 2017 (the AHI strategy).

Results

Before implementation of the AHI strategy, the proportion of AHI among HIV diagnoses was 0.6% (5/876); after implementation this was 11.0% (15/137). Median time (in days) to viral suppression during periods 1, 2, 3a, and 3b was 584 (interquartile range [IQR], 267–1065), 230 (IQR, 132–480), 95 (IQR, 63–136), and 55 (IQR, 31–72), respectively (P &lt; .001).

Conclusions

Implementing the AHI strategy was successful in diagnosing AHI and significantly decreasing the time between HIV diagnosis and viral suppression.
