More News from the 25th Conference on Retroviruses and Opportunistic Infections (CROI)

 

Since the volume of HIV research reported at major conferences such as CROI is vast, the specialty HIV, medical, and scientific press typically continue to summarize key research findings for several weeks after these events conclude.  In the last issue of In Brief, we curated earlier news coverage from CROI, and here we continue with later reports.  For your convenience, we have again curated news headlines by topic, so that you may quickly review important developments and then explore in depth the news of greatest interest to you.  

 

Summary Article

HIV/AIDS Epidemiology 

 

IHS Provider Data Show Higher HIV Diagnosis Rates Among American Indian/Alaska Natives Than NHSS Data

The rates of new HIV diagnoses among American Indian/Alaska Natives (AI/ANs) reported in a recent study of provider data from the Indian Health Service (IHS) were nearly twice as high as figures for the AI/AN population reported in the National HIV Surveillance System (NHSS) data. For their study, a research group from IHS, CDC, and other agencies serving AI/ANs analyzed provider data from IHS’s National Patient Information Reporting System (NPIRS) during the 10-year period from 2005 through 2014.  NPIRS includes 45 hospitals and more than 300 health centers located in 34 U.S. states and consists mainly of primary care clinics in rural areas that are federally or tribally operated. 

 

In contrast to the NHSS data, which estimated AI/AN HIV diagnosis rates as rising from 7.4/100,000 in 2010 to 8.8/100,000 in 2015, the IHS study found substantially higher but relatively stable rates – averaging 15.1/100,000 annually from 2005 to 2014. Of AI/ANs served by IHS facilities, males accounted for about two-thirds of new HIV diagnoses during the entire period studied, and the rate of new diagnoses among males was more than twice that in females (21.3 versus 9.5 per 100,000).  AI/ANs in the Southwest region of the U.S. accounted for nearly half (45%) of the total new HIV diagnoses reported in the study, and had higher annual diagnosis rates (19.9/100,000) than any other region. 

 

The authors noted that racial/ethnic misclassification may account, in part, for the roughly two-fold higher HIV diagnosis rates seen in the NPIRS data compared to NHSS estimates. “Racial misclassification among AI/ANs is rare in the IHS because documentation of AI/AN status is required to determine patient eligibility. Therefore, from the point of view of racial misclassification, we consider IHS NPIRS data to be a more accurate representation of the AI/AN population.” They concluded, “AI/ANs aged 20-54, particularly men, may benefit from increased HIV prevention and screening efforts. Our findings on HIV trends may help tribal, federal, and state health entities serving tribal nations better target efforts on HIV prevention, screening, and linkage to care among AI/ANs.” 

 

Pre-Exposure Prophylaxis

 

New State-by-State PrEP-Use Map from AIDSVu

AIDSVu recently released the first-ever, interactive, state-level maps summarizing trends in the use of PrEP across the U.S. According to the data, PrEP use increased at an average rate of about 73% annually during the period from 2012 through 2016, rising to a total of more than 77,000 PrEP users nationwide by 2016. The AIDSVu site provides interactive maps illustrating HIV prevalence, new HIV diagnoses, and mortality – and now PrEP use – across the United States. AIDSVu is a project of Emory University’s Rollins School of Public Health in partnership with Gilead Sciences and the Center for AIDS Research (CFAR) at Emory. Selected highlights of PrEP data on the AIDSVu site are summarized below.  Please note that, unless otherwise indicated, the data presented are for 2016 – the latest year for which detailed data are available.

  • the number of PrEP users increased 880% between 2012 and 2016, rising from about 8,768 users to 77,120 users during the period;
  • 93% of all PrEP users were male, and 7% were female;
  • nearly half of all PrEP users were located in just five states: New York, California, Florida, Texas, and Illinois;
  • the highest rates of PrEP use – as measured by the number of persons using PrEP per 100,000 population – were in New York, Massachusetts, Rhode Island, Washington, and Illinois; and 
  • the Northeast region had the highest rate of PrEP use per 100,000 population (47.4) – approximately double that in the West (28.1), the Midwest (23.5), and the South (22.6).

To mark the launch of its PrEP maps, the AIDSVu blog posted several recent interviews in which HIV experts discuss PrEP usage trends, access, and gender disparities in question-and-answer format. 

 

Public Health Service Updates Its Clinical Practice Guidelines for PrEP

The U.S. Public Health Service (PHS) recently published updated Clinical Practice Guidelines on the use of PrEP for HIV prevention in the United States. The revised guidelines include new data on the safety and efficacy of PrEP, indications for PrEP use, laboratory tests and diagnostic procedures, and considerations – such as potential drug interactions – when providing PrEP to persons at risk for HIV infection.  PHS notes that recent updates to the guidelines are highlighted in yellow throughout the document and “are intended solely to update the developing evidence base or to clarify specific points in clinical care. No changes were made to the graded recommendations for the use of PrEP in the U.S.”

 

HIV Guidelines and Drug Guide 

 

Biktarvy Now Classified as a Recommended Initial Regimen for HIV

On March 7, the Guidelines for the Use of Antiretroviral Agents in Adults and Adolescents Living with HIV panel issued a statement indicating that the fixed-dose combination pill Biktarvy is now classified as one of the recommended initial regimens for most people living with HIV.  Biktarvy combines the integrase strand transfer inhibitor (INSTI) bictegravir (BIC) with the drugs tenofovir alafenamide (TAF) and emtricitabine (FTC).  According to AIDSinfo, “BIC/TAF/FTC [marketed as the combination pill Biktarvy] is an effective and well-tolerated INSTI-based regimen for initial therapy in adults with HIV, with efficacy that is noninferior to DTG/ABC/3TC and DTG [dolutegravir]plus TAF/FTC for up to 48 weeks. On the basis of these clinical trial results, the Panel classifies BIC/TAF/FTC as one of the Recommended Initial Regimens for Most Adults with HIV.”

 

Perinatal Guideline Panel Adds Guidance on Breastfeeding

The DHHS guidance document, Recommendations for the Use of Antiretroviral Drugs in Pregnant Women with HIV Infection and Interventions to Reduce Perinatal HIV Transmission in the United States, has been updated to include a section on counseling and managing the care of HIV+ women who wish to breastfeed.  According to AIDSinfo, “While the Panel does not recommend breastfeeding for women with HIV, this section is intended to provide tools to help providers counsel women living with HIV on the potential risks associated with breastfeeding and to provide a harm-reduction approach for women who choose to breastfeed despite intensive counseling. This section is not intended to be an endorsement of breastfeeding, nor is it a recommendation to breastfeed for women living with HIV in the United States.”

 

TPAN Publishes 2018 HIV Drug Guide 

As part of its March/April issue of Positively Aware, TPAN has published its 22nd annual HIV Drug Guide. The Guide is composed of several sections:

  • “Getting the Most out of Your Drug Guide” has tips on using the guide to make informed HIV treatment decisions;
  • “State of the Art” is a review of the available antiretroviral therapies for treating HIV and an HIV specialist’s suggestions to help persons living with HIV choose regimens tailored to their needs;
  • “Standard Practice” is a summary of the DHHS HIV treatment guidelines; 
  • “Know Where to Look” is a guide to finding copay and patient assistance programs to help cover the cost of HIV medications; 
  • “Down the Road” is a look at new HIV drugs, HIV treatment strategies, and other expected developments in 2018 and beyond; and 
  • “Find Your Drug Below” is an A to Z listing of all single-drug and combination pills currently used for the treatment of HIV.  

For each medication, the Guide provides information about the drug maker, wholesale price, standard dosing, potential side effects and toxicity, potential drug interactions, and additional relevant information. The drug listings also include different perspectives on each drug and combination through physician and activist comments.
