Case • 15 yo • Recurrent pneumonia and then PcP • Started kivexa, efavirenz • Good VL, CD4 response • VL undetectable for more than 1 year • CD4 400
Why? • Not adherent to medication? • On wrong medication? • Should still be on septrin? • Has developed resistance to penicillin? • Susceptible because of rheumatic fever? • That’s what happens • Blame National Express
