Predicting clinical decompensation in patients with cirrhosis using the Hepquant‐SHUNT test

Abstract

SummaryBackgroundEarly identification of risk for decompensation in clinically stable cirrhotic patients helps specialists target early interventions and supports effective referrals from primary care providers to specialty centres.AimsTo examine whether the HepQuant‐SHUNT test (HepQuant LLC, Greenwood Village, Colorado, USA) predicts decompensation and the need for liver transplantation, hospitalisation or liver‐related death.MethodsThirty‐five compensated and 35 subjects with a previous episode of decompensation underwent the SHUNT Test and were followed for a median of 4.2 years. The disease severity index (DSI) (range 0‐50) was examined for association with decompensation in compensated patients; and liver transplantation, liver‐related death, and the number and days of liver related hospitalisations in all. DSI prediction of decompensation was also evaluated in 84 subjects with compensated cirrhosis from the Hepatitis C Antiviral Long‐Term Treatment against Cirrhosis Trial (HALT‐C) followed for a median of 5.8 years.ResultsAt baseline, subjects with prior decompensation had significantly higher DSI than compensated subjects (32.6 vs 20.9, P < 0.001). DSI ≥24 distinguished the decompensated from the compensated patients and independently predicted adverse clinical outcomes (hazard ratio: 4.92, 95% confidence interval: 1.42‐17.06). In the HALT‐C cohort, 65% with baseline DSI ≥24 vs 19% with DSI <24 experienced adverse clinical outcomes (relative risk 3.45, P < 0.0001).ConclusionsThe SHUNT test is a novel, noninvasive test that predicts risk of decompensation in previously compensated patients. DSI ≥24 is independently associated with risk for clinical decompensation, liver transplantation, death and hospitalisation.
