Reports of resistance to integrase strand transfer inhibitors (INSTIs) are now not uncommon. We analyzed the HIV int gene from plasma of antiretroviral-naïve individuals during acute and chronic HIV-1 infection. No individual with major INSTI mutations was identified. Two individuals harbored INSTI accessory mutations E157Q/T97A were detected for the first time. Our results emphasize the need to consider testing for INSTI resistance at baseline as this class of drugs is increasingly used in clinical routine.
