IAS-USA releases new recommendations on ARVs

The International Antiviral Society-USA Panel has released updated guidelines for using antiretroviral drugs for the treatment and prevention of HIV in adults.
The recommendations, published in JAMA, are an update from 2014 due to “substantial advances in the use of antiretroviral drugs (ARVs),” Huldrych F. Günthard, MD, from the division of infectious diseases and hospital epidemiology at University Hospital Zurich, and colleagues wrote.
The revised recommendations describe the latest developments in the uses of ARVs, including:
The authors assembled a panel of HIV experts to assess data from peer-reviewed journals, conference abstracts and regulatory agencies. Each recommendation was graded on both the quality and strength of available evidence.
The panel, which also included Infectious Disease News Chief Medical Editor Paul A. Volberding, MD, issued a strong recommendation with high-quality evidence that ART be used for all patients infected with HIV with detectable viremia, regardless of CD4 cell count. They recommended several optimal regimens, which consist of two nucleoside reverse transcriptase inhibitors (NRTIs) and an integrase strand transfer inhibitor (INSTI). The following regimens received strong recommendations with high quality evidence:
They reported that other regimens, such as nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with two NRTIs, also are effective.
There was strong, high-quality evidence for pregnant women with HIV to initiate ART for their health and to reduce HIV transmission, and for patients coinfected with hepatitis B virus infection and HIV to initiate ART with tenofovir disoproxil fumarate (TDF) or TAF, lamivudine or emtricitabine and another component.
The panel issued other recommendations for special populations, such as using Baraclude (entecavir, Bristol-Myers Squibb) for patients who have HBV; ensuring that patients with hepatitis C virus infection and HIV utilize ART regimens that do not interact with other therapies; not using TDF for patients with osteoporosis or osteopenia; and monitoring patients with kidney disease when ART is initiated or changed.
As detailed in the guidelines, some patients who achieved virologic suppression with older regimens may benefit from switching to a single-pill regimen, such as dolutegravir/abacavir/lamivudine, elvitegravir/cobicistat/TAF/emtricitabine, Stribild (elvitegravir/cobicistat/emtricitabine/TDF, Gilead Sciences) or Complera (rilpivirine/emtricitabine/TDF, Gilead Sciences). Some scenarios in which patients may want to switch include food restrictions, adverse effects, drug interactions, pregnancy or drug toxicities, the authors wrote.
The panel also stressed the importance of improving access to care and retention.
“Achieving the full benefits of treatment and prevention afforded by ART requires early diagnosis, rapid linkage to care, continuous retention in care, and uninterrupted access and adherence to ART,” Günthard and colleagues wrote. “Late diagnosis and presentation for HIV care are global challenges that have improved only modestly over decades. To avoid missed opportunities for earlier diagnosis, routine opt-out HIV screening is recommended in primary medical care settings and emergency departments and for all pregnant women.”
They suggested various approaches, including brief case management after HIV diagnosis and phone and text reminders before appointments and after missed appointments, both of which had strong and high-quality evidence.
Finally, the researchers issued strong recommendations with high-quality evidence for daily Truvada (TDF/emticitabine, Gilead Sciences) as pre-exposure prophylaxis to prevent HIV infections in high-risk individuals, such as those “from a population with an HIV incidence of at least 2% per year of HIV-infected persons who do not have viral suppression.”
In an accompanying editorial, Kenneth H. Mayer, MD, and Douglas S. Krakower, MD, both affiliated with The Fenway Institute, Beth Israel Deaconess Medical Center and Harvard Medical School, wrote that “the current IAS-USA guidelines reflect the hard-won success of 35 years of clinical research. Although challenges remain to optimize the cascade of care and to prevent new infections, and an aging epidemic will present new challenges, these concerns reflect the successes of highly effective antiretroviral therapy.”
Mayer and Krakower concluded: “Historians may wonder whether the pace of discovery in the early days of the epidemic could have been accelerated, but no one can doubt the signal accomplishments of biobehavioral research and community engagement in forging a common strategy to deal with this global pandemic, one that continues to pose new challenges.” – by Chelsea Frajerman Pardes
