Differential diagnosis for febrile diarrhea similar in HIV/AIDS patient vs non-HIV/AIDS patient with a few exceptions:
- Parasitic infections (Cyclospora, Microspora, Isospora, Giardia) --> tend to be subacute/chronic in onset
- Mycobacterial infections (e.g. MAC) tend to be more chronic
- MAC and CMV colitis usually occur in patients with CD4 count < 50-100 cells/mm3
- Concomitant infections are common so need to work up for C. diff (if risk factors), other enteric bacteria, and O&P

Abacavir hypersensitivity syndrome: occurs in patients with haplotype HLA-B*5701 --> fever, diarrhea, rash, typically within 6 weeks of starting abacavir
- All patients now tested for this HLA haplotype prior to being started on abacavir (negative predictive value is 100% for developing the hypersensitivity syndrome)
