Default CD4 counts are useful landmarks for initiation of prophylaxis

I think it's important to know when to start prophylaxis in immunocompromised patients;
The following CD4 counts are useful landmarks for initiation of prophylaxis:
  • < 200 cells/μL - PCP prophylaxis
  • < 100 cells/μL -Toxoplasmosis prophylaxis (if seropositive)
  • < 50 cells/μL Mycobacterium avium-intracellulare infection prophylaxis
Please feel free to add

Prophylaxis for Toxo is given if u r sero negative
If u r sero positive, it implies that u r already been exposed 2 it & u r immune 2 it. so no need of prophylaxis

ag2011n was right

Toxo prophylaxis for those who are sero positive
Bcoz Toxo happens in AIDS pts due to reactivation of primary infection, when their CD 4 drops below 100 (this is something like tb)
