The epidemiology of HIV infections among people who inject drugs is changing, with overdose deaths, a major public health concern.

Several countries and cohorts have demonstrated the remarkable impact that universal HCV testing and unrestricted access to hepatitis C treatment can have on markedly reducing incident HCV infections and HCV infection prevalence, including in people who inject drugs and HIV/HCV-coinfected populations. However, in many settings, substantial barriers to widespread HCV treatment remain, including undiagnosed HCV infection, particularly in populations outside the standard \"baby boomer\" birth cohort (ie, born 1945-1965); restricted access to hepatitis C treatment in those with known HCV infection; reinfection with HCV; and migration of HCV-infected populations. Many innovative programs have successfully implemented HCV testing and treatment outside of traditional care settings, expanding access for harder-to-reach populations, which will be crucial to successful elimination efforts.

PrEP efficacy is strongly associated with adherence. In clinical trials, PrEP has been more effective in men who have sex with men and HIV-serodiscordant heterosexual couples than in women, likely reflecting pharmacokinetic differences between levels of tenofovir disoproxil fumarate in vaginal and rectal tissues, and poorer adherence in studies in women. Current guidelines recommend daily PrEP for men and women; however, PrEP taken at least 4 days per week for men may be as effective as daily PrEP, and women must take PrEP 6 to 7 days per week to maximize efficacy. Data are accumulating on the effectiveness of pericoital PrEP for men who have sex with men, but it is not yet recommended in the United States. PrEP is underprescribed for younger individuals, black individuals, and Hispanic and Latino individuals. This article summarizes a presentation by Susan P.

Despite 31 currently approved drugs, the pipeline of investigational HIV drugs remains full. Investigational antiretroviral drugs include the nucleoside analogue reverse transcriptase translocation inhibitor (NRTTI) MK-8591, a long-acting compound that could be dosed once weekly. Investigational nonnucleoside analogue reverse transcriptase inhibitors (NNRTIs) include doravirine, which is active in vitro against NNRTI-resistant HIV and was potent and well-tolerated when used in combination with a dual-nucleoside analogue RTI (nRTI) backbone in treatment-naive individuals.New integrase strand transfer inhibitors (InSTIs) include recently approved bictegravir, which is active against InSTI-resistant viral strains in vitro and was potent and well-tolerated in combination regimens in treatment-naive individuals, and investigational cabotegravir, which is being studied with monthly parenteral dosing for HIV maintenance treatment and with bimonthly dosing for HIV preexposure prophylaxis (PrEP). Investigational HIV entry inhibitors include the new CD4 attachment inhibitor fostemsavir, which targets HIV envelope glycoprotein 120, and recently approved ibalizumab, which binds the CD4 receptor.
