Pre-screening could help identify NAFLD biopsy candidates

While it’s the most accurate means to diagnose and stage severity of NASH, biopsy is invasive, costly, and associated with potential complications, according to a recent Hepatology review article (2017 Dec 9. doi: 10.1002/hep.29721).

Criteria to pinpoint patients at highest risk for NASH and fibrosis could be useful for streamlining clinical trial enrollment and limiting screening failures, according to authors who recently described the pre-screening criteria in the Journal of Hepatology (2018 Feb. doi: 10.1016/j.jhep.2017.10.015).

Patients at a high risk of having advanced fibrosis include those who are over the age of 50, Hispanic, diabetic, or hypertensive, or who have a vibration controlled transient elastography (VCTE, FibroScan) score of kPa greater than 8.5, or an AST/ALT ratio greater than 1, among several other criteria described in the article.

“The patients who have a low likelihood of NASH and fibrosis are those who are under the age of 40, who may not be diabetic, who have a elastography score of kPa less than 7, or an AST less than 20,” Dr. Rustgi said of the pre-screening criteria.
