IRIS Risk Factors in People with Advanced HIV - Clinical Research Update 9.15.2020

    A study about the risk factors for Immune Reconstitution Inflammatory Syndrome in people with advanced HIV disease is the subject of this week's Clinical Research Update.  While we are seeing fewer patients with advanced AIDS, this study suggests some strategies for identifying risk for IRIS for those that do present to our clinics.

    Hello, 
    I wonder if you might be able to comment about one of my challenging patients:
    JL is an AA M in his early 50's, Dx'd with HIV in or before 2012 (as far as current records are available). nonadherence to HIV meds. 
    CD4s most recently 75, but have ranged from 166 (in 2019) to 4 (in 2017);  HIV Viral Loads most recently 329,000, and ranging from ~100-300k, with a nadir of 120 in 2019, and Not Detectable in 2017. VL bounce back up due to his non-adherence to meds. Most recent HBG 10.9. C-RP pending.

    Besides OI suppressive therapy (azithro for MAC, bactrim for PCP/PJ, fluconazole for crypto, and valacyclovir for HSV/VZ.  ARTs over the last 10 years have included: Norvir, Reyataz, Truvada, Stribild, Prezista, Isentress, and most recently, Prezcobix & Tivicay.  He also takes amlodipine and atorvastatin for HTN and DLD, respectively, and misses doses as well (with less severe consequences!). 

    Just completed his HAV/HBV and pneumo 23 vax series, but has not yet had COVID vax, but uncertain of it's effectiveness due to his immune status. Nonetheless, will try to schedule him for injection. 

    We are concerned about potential risk for IRIS, if we can actually get him to remain on meds (such as Biktarvy) consistently.  He has "no time" for hospitalization for induction of therapy, but since IRIS can occur anytime up to 6 months following reinstitution of ART, am not sure whether that represent a significant concern.  

    Any suggestions for an effective approach? Should we subject him to therapy given his risk for IRIS?  He is also resistant to behavioral therapy.  

    Best wishes,

    I've never heard of anyone being hospitalized just in case they get IRIS, and I doubt you could get coverage for that hospitalization. This man's greatest risk is not IRIS, but death from AIDS if he remains untreated. You can always deal with IRIS if it happens.

    I dont have a recommendation re: iris prevention other than you need to be a look out for it - but question:  did the pt have crypto to start with?  I personally have never put someone on crypto prophylaxis if they did not have crypo and prophylaxis for HSV?  What was your rationale here with this prophylaxis?

    I wouldn't worry about IRIS. While you are right to think about the possibility, it is not common, and should not be an impediment to treat the HIV. I would not prophylax against CMV as you are doing. That practice recommendation changed a few years ago no longer advising it. And glad you are providing Covid vaccine. A third shot of mRNA vaccine will likely be recommended when CDC updates their guidance.

    To add to other comments- unsure of the need for all that prophylaxis unless pt actually has the disease. Bactrim - sure for PCP. Azithro - sure for MAC (that guideline also changed once the pt is successfully stays on ARVs). As Joel said, his biggest risk is death from AIDS and IRIS can be dealt with. I would follow this pt very closely, monitor kidney function on Bactrim etc. and keep them engaged - that's the most important agenda.

    Also to be honest, I would have waited to vaccinate him for HAV/HBV till cd4 builds up more so he can actually mount immunity. Since you already did I would check immunity in few months. If not immune, I would wait to vaccinate till his counts increase and have an immune system. Other vaccines like PCV13, PPSv23 (which you did) and Menactra are important ones to give now.

    He is on a lot of preventative medications. I am assuming he has cryptococcus via a positive crypto latex antigen and you are consistently monitoring his titers? Biktarvy and Bactrim DS should suffice unless he has very symptomatic Herpes 1,2; or Herpes 5(CMV) with symptomatic response such as photo sensitivity headaches lymphadenopathy a very low EIPS score of 4 or below (malaise) etc. ARV consistently reduces the risk of developing these opportunistic infections. Bactrim DS would be the most appropriate prophylaxis only, if the patient doesn't have other markers such as crypto or CMV. Applying all of these medications can increase the risk of pill exhaustion just coming out of the gate. That and other risks associated with adverse effects of which medication they perceive to be causing problems.
