BACKGROUND: The accuracy of current criteria for ruling out large oesophageal varices (LEV) and other endoscopic lesions of portal hypertension (PH) may be compromised by obesity and MASLD/MASH.
AIMS: In the US multicentre SHUNT-V study, we evaluated the disease severity index (DSI) for detecting LEV and other lesions of PH at endoscopy.
METHODS: Subjects were adults with compensated cirrhosis scheduled for endoscopy to screen for varices. DSI was calculated from clearances of labelled cholates after oral and intravenous administration. DSI ≤ 18.3 was evaluated as a cut-off for ruling out LEV with acceptance criteria of negative likelihood ratio < 0.52 and sensitivity > 85%.
RESULTS: SHUNT-V enrolled 306 subjects; 275 had both DSI and endoscopy, and 238 had Child-Pugh A cirrhosis (52.1% MASLD/MASH, 25.2% chronic hepatitis C and 15.6% alcoholic liver disease; 87% were overweight, 64% were obese and 54% had diabetes). AUROCs for DSI ranged from 0.81 to 0.82 for LEV and 0.79 to 0.80 for all significant PH lesions. DSI 18.3 had sensitivity 96.3%-100% for LEV and 97.3%-100% for all significant PH lesions. If DSI ≤ 18.3 were used as the sole determinant to defer EGD, 27%-35% of EGDs could have been avoided with 0%-3.7% of LEV and 0%-2.7% of all significant PH lesions missed.
CONCLUSIONS: HepQuant DSI predicts the likelihood of LEV and significant PH lesions across a spectrum of patient characteristics and disease aetiologies. DSI, based on liver function and portal-systemic shunting, can aid in the decision to defer endoscopy for varices in patients with Child-Pugh A cirrhosis.
TRIAL REGISTRATION: The SHUNT-V study was registered at ClinicalTrials.gov (NCT03583996).
