Co-Infection with active TB

  • 1.  Co-Infection with active TB

    ​Good afternoon all.

    I have a new to me HIV patient who is co-infected with TB. sputums are now negative. Diagnosed in 2013, but never started medications. I did rapid start with Biktarvy, but when the Rifampen and Isoniazid were started his liver enzymes skyrocket. I held Rifampen and Isoniazid for 2 weeks per ID recommendation, liver enzymes normalized.

    My question or I am looking for recommendations for treatment options. Patient has been compliant with medications and is almost undetectable at this time.

    Thank you for the guidance and recommendations.
    Shannon

    Hi Shannon - there is a major drug drug interaction between Biktarvy (CONTRAINDICATED with bictegravir and aovid use with TAF). I actually dont think that is the reason the LFTs bumped as INH and RIF together can cause that which is why they should be monitored closely and close attention to dosing is important, however I would look for an alternative to the antiretroviral. What we have done in our office is done BID Tivicay with either Truvada or Epzicom (so we have done Triumeq QD and Tivicay 12 hr after triumeq) and use Rifabutin and NOT rifampin. I would suggest getting an AAHIVP PharmD involved in this case to mitigate any DDI issues.

    Hi Shannon,

    We typically use DTG dosed twice daily plus FTC/TDF for our HIV/TB co-infected patients. You could also swap PZA for Moxi which is a less offensive to the liver but I definitely suggest consulting with a PharmD who is experienced in managing TB/HIV. How many days of full RIPE did he get in before the liver enzymes went up? Just curious, when you said sputums are now negative do you mean actual AFB cultures or the smears? 

    Thank you for sharing the case and for the learning opportunity.

    Shannon,
    The federally-funded National HIV Curriculum's Latent Tuberculosis Infection has extensive treatment options for you to consider.  

    BTW, If you register on the site, you can also earn free CNE and we also offer a lot of free pharmacology CE for advanced practice nurses.

    I think the sudden elevation of liver enzymes is due to IRIS(Immune reconstitution and  inflammatory syndrome)
