Mr. Y’s HIV is being managed on a combination drug regimen that includes two nucleoside reverse transcriptase inhibitors (NRTIs) and one protease inhibitor (PI). His viral load is currently 50,000 copies/ mL; 3 months ago, his viral load was undetectable. His CD4+ T-lymphocyte count is 526 cells/mm3, down from 680 cells/mm3 3 months ago. Although he has been following his HAART regimen, he has experienced multiple complications, including several opportunistic infections. In light of his medical history, Mr. Y is especially concerned about his shortness of breath and hemoptysis. 1.What is the mechanism of action of the NRTI drugs that Mr. Y is taking for his HIV? 2. What is the rationale for the use of combined drug therapy in the treatment of HIV?
