Episode notes
Laila's Clinic Pick About A Remarkable Transplant Recovery
- Laila Woc-Colburn shared a patient pick: a liver transplant recipient who improved dramatically in one month.
- The patient came in near death with bilirubin ~25 and walked into clinic well one month later, which delighted Dr. Woc-Colburn.
Latent TB Can Reactivate When Immune Control Fails
- Latent TB is a dormant, non-contagious infection that can reactivate when immune control fails.
- About 15% of latent infections eventually progress to active disease, especially with immunosuppression or aging, explained by Laila Woc-Colburn.
LTBI Treatment Has Different Value In High Incidence Settings
- In high-incidence countries LTBI treatment is often not offered because reinfection is common and single-drug therapy can drive resistance.
- Public health context matters: treating LTBI is valuable in low-incidence settings like the U.S., per Laila Woc-Colburn.
