BACKGROUND & AIMS:Studies to evaluate risks of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus (HBV) infection treated with the nucelos(t)ide analogues entecavir or tenofovir have produced contradictory results. These differences are likely to be the result of censored data, insufficient observation periods, and different observation periods for patients treated with different drugs. We aimed to compare the incidence of HCC development between patients treated with oral entecavir or tenofovir and followed up for the same time periods.
METHODS:We performed a retrospective study, collecting data from 1560 treatment-naive patients with chronic HBV infection who were first treated with entecavir (n [ 753) or tenofovir (n [ 807) from 2011 through 2015 at 9 academic hospitals in Korea. Clinical outcomes were recorded over a mean time period of 4.7 -1.0 years, from 92.4% of patients treated with tenofovir and 92.7% of patients treated with entecavir.
RESULTS:Thirty-four patients in the entecavir group (4.5%) and 45 patients in the tenofovir group (5.6%) developed HCC during the follow-up period. The incidence of HCC did not differ significantly between groups, even in a 516-pair propensity score-matched population.
CONCLUSIONS:In a retrospective study of 1560 treatment-naive patients with chronic HBV infection, the incidence of HCC did not differ significantly between patients treated with entecavir vs tenofovir over the same observation period. Clinical trial: KCT0003487.
SWE showed a significant correlation with the severity of liver fibrosis and was useful and accurate to predict significant and advanced fibrosis, comparable with serum markers.
Background/AimsThis study evaluated the clinical outcomes of balloon-occluded retrograde transvenous obliteration (BRTO) for the treatment of hemorrhage from gastric varices (GV) in Korean patients with liver cirrhosis (LC).MethodsWe retrospectively analyzed data from 183 LC patients who underwent BRTO for GV bleeding in 6 university-based hospitals between January 2001 and December 2010.ResultsOf the 183 enrolled patients, 49 patients had Child-Pugh (CP) class A LC, 105 had CP class B, and 30 had CP class C at the time of BRTO. BRTO was successfully performed in 177 patients (96.7%). Procedure-related complications (e.g., pulmonary thromboembolism and renal infarction) occurred in eight patients (4.4%). Among 151 patients who underwent follow-up examinations of GV, 79 patients (52.3%) achieved eradication of GV, and 110 patients (72.8%) exhibited marked shrinkage of the treated GV to grade 0 or I. Meanwhile, new-appearance or aggravation of esophageal varices (EV) occurred in 54 out of 136 patients who underwent follow-up endoscopy (41.2%). During the 36.0±29.2 months (mean±SD) of follow-up, 39 patients rebled (hemorrhage from GV in 7, EV in 18, nonvariceal origin in 4, and unknown in 10 patients). The estimated 3-year rebleeding-free rate was 74.8%, and multivariate analysis showed that CP class C was associated with rebleeding (odds ratio, 2.404; 95% confidence-interval, 1.013-5.704; P=0.047).ConclusionsBRTO can be performed safely and effectively for the treatment of GV bleeding. However, aggravation of EV or bleeding from EV is not uncommon after BRTO; thus, periodic endoscopy to follow-up of EV with or without prophylactic treatment might be necessary in LC patients undergoing BRTO.
The success rate of spleen stiffness measurement is lower than that of liver stiffness measurement. Spleen stiffness measurement is affected by abdominal wall thickness and spleen size.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
