ABSTRACT
There are no data validating the performance of spleen stiffness measurement in ruling out high-risk varices in patients with HBV-related cirrhosis under maintained viral suppression. Thus, we aimed to prospectively validate the performance of spleen stiffness measurement (cut-off 46 kPa) combined with Baveno VI criteria in ruling out high-risk varices in these patients.Patients with cirrhosis were enrolled from April to December 2019 at the hepatology unit of the Nanfang Hospital, China. Liver and spleen transient elastography and esophagogastroduodenoscopy were performed at enrollment. Antiviral regimen(s) and virological responses, evaluated every 3-6 months, were recorded.Overall 341 patients with HBV-related cirrhosis under maintained viral suppression were enrolled, and the prevalence of high-risk varices was 20.5% (70/341). Baveno VI criteria spared 37.0% (126/341) esophagogastroduodenoscopies and no high-risk varices were missed (0/70). Eight cases of high-risk varices (8/70, 11.4%) were misclassified in patients (208/341, 61.0%) within the expanded Baveno VI criteria. The spleen stiffness measurement cut-off (≤46.0 kPa) was shown to safely rule out high-risk varices in these patients (the percentage of missed high-risk varices was 4.3%). Over half (61.6%, 210/341) of patients met the combined model (Baveno VI criteria and spleen stiffness measurement cut-off ≤46 kPa) and 4.3% (3/70) of high-risk varices cases were misclassified. This combined model exhibited a sensitivity of 95.71%, specificity of 76.38%, negative predictive value of 98.57%, and negative likelihood ratio of 0.06 for ruling out high-risk varices.We validated the excellent performance of Baveno VI criteria combined with spleen stiffness measurement (cut-off 46 kPa) for safely ruling out high-risk varices in patients with HBV-related cirrhosis under viral suppression; more than half of esophagogastroduodenoscopy procedures were spared using this combination.NCT04123509 LAY SUMMARY: Esophageal varices have important prognostic implications in patients with cirrhosis. Thus, their timely identification is important so that treatment can be initiated early. Herein, we validated the excellent performance of the combination of Baveno VI criteria with spleen stiffness measurement (cut-off 46 kPa) for ruling out high-risk esophageal varices in patients with HBV-related cirrhosis under maintained viral suppression (with antiviral treatment). This combined model was able to safely rule out high-risk varices (missed/total <5%) and over half (61.6%) of esophagogastroduodenoscopy procedures were spared.
