#178 Tuberculosis Updates with Laila Woc-Colburn MD

This episode of The Curbsiders explores the complexities of tuberculosis (TB) diagnosis, treatment, and screening. Dr. Laila Woc-Colburn, an infectious disease expert, guides hosts Matthew Watto and Hannah R. Abrams through differentiating latent TB infection from active TB disease, emphasizing the importance of considering individual risk factors and the limitations of traditional PPD testing. The discussion covers interpreting interferon-gamma release assays (IGRAs) and navigating indeterminate results, as well as the latest CDC guidelines for TB screening among healthcare workers. Treatment options for latent TB are reviewed, including the new 12-week isoniazid-rifapentine regimen, with a focus on potential side effects and drug interactions. The hosts also discuss the challenges of managing active TB cases, including isolation protocols and the role of direct observed therapy (DOT) to ensure medication adherence.
