S5 - E5.2 - NITs In The Diagnosis and Treatment Of Advanced MASH Fibrosis Patients

Send us Fan MailThis conversation explores the challenges with using the current non-invasive tests (NITs) to diagnose patients with F2/F3 advanced MASH fibrosis. If tests today cannot achieve the requisite level of precision, panelists explore other ways to define patient targets. Roger Green starts by recalling that in a recent episode (Season 5 Episode 2), Jeff McIntyre suggested that in the US, the initial patient population may be as small as a few hundred thousand people. Ian Rowe states that current tools are incapable of placing these patients in a narrow diagnostic or therapeutic window. Jörn Schattenberg takes a "pragmatic" approach to defining the patient he is certain to treat; test results are a small part of his calculus. Naim Alkhouri shifts the discussion to focus on VCTE cutoff points for cirrhosis. The interplay between Naim and Ian suggests that different practices and guidelines carry with them different cutoffs. Jörn expresses gratitude that the can watch the US and learn from that experience. He notes the tension between wanting a cost-effective system and large numbers of patients clamoring for the new medicine. The need to rule some patients out is obvious, the way to do so is challenging. Asking, "What can we do besides scan" or use conventional tests, Naim discusses some newer options, starting with the metabolomics-based MASEF score discussed in Season 4 Episode 39. He also mentions the LiverFast test. Jörn describes factors that can render a test inappropriate for a particular patient. Louise suggests the right test will depend on the specific question the provider is trying to answer.
