Abstract
Direct-acting antivirals (DAAs) show high efficacy and safety in HCV-cirrhotic patients, but most maintain clinically significant portal hypertension after sustained virological response (SVR). Non-invasive Baveno and expanded-Baveno criteria can identify patients without high-risk gastroesophageal varices (GEV) whohave no need for endoscopic surveillance. However, data after SVR are scarce. We performed a multicenter study to evaluate SVR effects over GEV and diagnostic accuracy of non-invasive criteria after SVR. HCV-cirrhotic patients receiving DAAs and baseline endoscopic evaluation were included (November 2014-October 2015). GEV were classified as low risk (LR-GEV) (< 5mm) or high risk (HR-GEV) (≥ 5mm or with risk signs). Transient elastography (TE) and endoscopy were performed during follow-up. SVR was achieved in 230 (93.1%) of 247 includedpatients, 151 (65.7%) with endoscopic follow-up. Among 64/151 (42.4%) patients without baseline GEV, 8 (12.5%) developed GEV after SVR. Among 50/151 (33.1%) with baseline LR-GEV, 12 (24%) developed HR-GEV. Patients with GEV progression showed TE ≥ 25kPa before treatment (64.7%) or ≥ 20kPa after SVR (66.7%). Only 6% of patients without GEV and LSM < 25kPa before treatment, and 10% of those with baseline LSM < 25kPa and LSM < 20kPa after SVR showed GEV progression after 36months. The negative predictive value of Baveno and expanded-Baveno criteria to exclude HR-GEV was maintained after SVR (100% and 90.7%, respectively). HCV-cirrhotic patients can develop HR-GEV after SVR. Surveillance is especially recommended in those with GEV before antiviral treatment. Baveno and expanded-Baveno criteria can be safely applied after SVR. https://clinicaltrials.gov: NCT02758509.
