Updated recommendations on first-line and second-line antiretroviral regimens and post-exposure prophylaxis and recommendations on early infant diagnosis of HIV: interim guidance
Update on antiretroviral regimens for treating and preventing HIV infection: Since 2016, WHO has recommended tenofovir disoproxil fumarate (TDF) + lamivudine (3TC) (or emtricitabine, FTC) + efavirenz (EFV) 600 mg as the preferred first- line antiretroviral therapy (ART) regimen for adults and adolescents. WHO recommended dolutegravir (DTG) as an alternative option to EFV for first-line ART because of the uncertainty regarding the safety and efficacy of DTG during pregnancy and among people living with HIV receiving rifampicin-based tuberculosis (TB) treatment. New WHO interim guidelines contain recommendations regarding preferred first-line regimens for adults, adolescents and children initiating ART, which now include DTG and RAL.
Update on early infant diagnosis of HIV: In 2016, WHO recommended that HIV virological testing be used to diagnose HIV infection among infants and children younger than 18 months and that ART be started without delay while a second specimen is collected to confirm the initial positive virological test result.
