YehiaBR, Mehta JM, Ciuffetelli D, et al. ClinInfect Dis2012;55:593-9. Conclusion: ART medication errors are typically corrected within 48 hours (if you have two ID specialist PharmD s reviewing all medication orders for: ART medication errors and ART drug interaction errors) Immune Reconsitution Inflammation Syndrome (IRIS) Unmasking IRIS Clinical presentation of preexisting, subclinical OI after HAART initiation Viable pathogens Usually 3 months of HAART Example: Non-tuberculous mycobacteria (MAC), TB Paradoxical IRIS Exacerbation and/or return of sxs of currently or recently treated OI Non-viable antigens of pathogens Usually 3 months of HAART Months to years for immune recovery (CMV) uveitis Examples: TB, Cryptococcal disease, Kaposi s sarcoma (KS) 8:30AM-5:30PM: 707-583-8819 (SRCHC x425) HIV Nurse Case Manager 24/7 HIV Specialist on-call: 707-583-8823 to reach cell phone of an HIV Specialist MD Newly diagnosed HIV+ pts: clients call 707-583-8816 for the HIV Outreach Worker.
