She recently underwent a complete physical examination with routine laboratory tests. She also had a Pap smear and testing for sexually transmitted diseases. Since her divorce 2 years ago, she had sexual encounters with random men at bars or social events and frequently did not use any form of contraception during sexual intercourse. She was shown to be positive for the human immunodeficiency virus HIV. Combination anti-retroviral treatment is initiated including zidovudine, didanosine, and efavirenz. One week later, she is rushed to the hospital where she is diagnosed with acute pancreatitis. Which of the following precautions will be required after pancreatitis resolves with treatment?? A: Frequent monitoring of CD4 cell count, B: Add ritonavir to the HIV treatment regimen, C: Replace efavirenz with nevirapine, D: Check hemoglobin levels, E: Replace didanosine with lamivudine,  <response>: This is a clinical vignette about a 35-year-old woman who was recently diagnosed with HIV and started on antiretroviral therapy. She developed acute pancreatitis likely as a side effect of didanosine, one of the medications she was prescribed. The question asks what precaution should be taken after her pancreatitis resolves. The choices mention modifying her HIV regimen by changing the medications. This makes sense as we want to avoid medications that could cause pancreatitis again. Specifically, didanosine is known to cause pancreatitis as a side effect. So the best choice would be to replace didanosine with another nucleoside reverse transcriptase inhibitor like lamivudine that has a lower risk of pancreatitis.E: Replace didanosine with lamivudine
