Background/Aims We investigated the efficiency of the indirect ratio of anti-HBc IgG at predicting HBsAg seroclearance in patients with nucleos(t)ide analogue (NA)-induced HBeAg seroclearance. Methods We performed a retrospective study that included 366 chronic hepatitis B patients (March 2007 to December 2016) at a single tertiary hospital. These patients were HBsAg seropositive, and experienced NA-induced HBeAg seroclearance. The indirect ratio of light absorbance of anti-HBc IgG levels were measured with chemiluminescent microparticle immunoassay using the Architect Anti-HBc assay (Abbott Laboratories, IL, USA) as a qualitative method prior to antiviral therapy. We calculated the cumulative incidences of HBsAg seroclearance based on the anti-HBc IgG levels. Results After a 10-year follow-up, 48 patients experienced HBsAg seroclearance (13.1%). Thirty-three of 179 patients who had an indirect ratio of light absorbance of anti-HBc IgG < 11 RLU (relative light unit) showed HBsAg seroclearance (18.4%); 15 of 187 patients who had an indirect ratio of light absorbance of anti-HBc IgG ≥ 11 RLU showed HBsAg seroclerance (8.0%) (p = 0.003). In multivariate analysis, age, and ALT at the time of HBeAg seroclearance were predictors of HBsAg seroclearance. Especially, the relative risk of HBsAg seroclearance in patients with baseline anti-HBc IgG levels < 11 RLU was 2.213 (95% CI, 1.220-4.014), compared to that in patients with higher levels of anti-HBc IgG at baseline (p = 0.009). Conclusion Using an indirect method for anti-HBc IgG levels, baseline anti-HBc IgG levels (< 11RLU), age (≥ 50 years), and ALT (≥ 40 IU/L) might be associated with HBsAg seroclearance in patients with NA-induced HBeAg seroclearance.
Cirrhosis has prognostic value. We investigated whether the combined use of ultrasonography (US) and transient elastography (TE) to diagnose cirrhosis is beneficial for the risk assessment of hepatocellular carcinoma (HCC) and liver-related events in patients with chronic hepatitis B (CHB). A total of 9300 patients with CHB who underwent US and TE in two institutions between 2006 and 2018 were enrolled. TE value ≥13 kPa was set to indicate cirrhosis. Patients were divided into four groups: US(+) TE(+) (cirrhosis by US and TE), US(+)TE(−) (cirrhosis by US, but not by TE), US(−)TE(+) (cirrhosis by TE, but not by US) and US(−)TE(−) (non-cirrhosis by US and TE).The patients were predominantly male (n = 5474, 58.9%) with a mean age of 47.5 years. The proportions of patients with cirrhosis diagnosed by US and TE were 17.2% (n = 1595) and 13.2% (n = 1225), respectively. The proportion of patients with discordant results in diagnosing cirrhosis by US and TE was 18.7% (n = 1740). During follow-up (median: 60.0 months), HCC and liver-related events developed in 481 (5.2%) and 759 (8.2%) patients, respectively. The cumulative incidence rates of HCC and liverrelated events were highest in the US(+)TE(+) group, intermediate-high in the US(−) TE(+) group, intermediate-low in the US(+)TE(−) group and lowest in the US(−)TE(−) group (overall p < .001). Cirrhosis assessed using US and TE was a major predictor of HCC and liver-related event development in patients with CHB. Cirrhosis assessed using TE seemed better in predicting HCC or liver-related events than using US, when cirrhosis diagnosis was discordant by US and TE.| 1363 YOO et al.
Background/Aims: There are no data regarding the association between sarcopenic obesity status and nonalcoholic fatty liver disease (NAFLD) and NAFLD-associated liver fibrosis. Therefore, we aimed to investigate the relationship between sarcopenic obesity status (sarcopenia only, obesity only, and sarcopenic obesity) and NAFLD and liver fibrosis in Korean adults.Methods: In total, 2,191 subjects completed a health checkup program, including abdominal ultrasonography and FibroScan. Subjects were classified into the following four categories: optimal body composition (nonobese and nonsarcopenic), sarcopenia only (nonobese), obesity only (nonsarcopenic), and sarcopenic obesity. Sarcopenic obesity was stratified by the skeletal muscle mass index and body fat using bioelectrical impedance analysis. NAFLD was diagnosed by ultrasonography, and liver fibrosis was assessed using transient elastography in subjects with NAFLD. Results:The prevalence of NAFLD and liver fibrosis significantly increased according to the sarcopenic obesity status. In the logistic regression analysis, after adjusting for multiple risk factors, the odds ratio (OR) for the risk of NAFLD was largest in the sarcopenic obesity group (OR, 3.68; 95% confidence interval [CI], 2.94 to 4.60), followed by the obesity only (OR, 2.25; 95% CI, 1.67 to 3.03) and sarcopenia only (OR, 1.92; 95% CI, 1.30 to 2.84) groups, when compared with the optimal group. Additionally, liver fibrosis was independently associated with sarcopenic obesity status (OR 4.69, 95% CI 1.95 to 11.29; OR 4.17, 95% CI 1.56 to 11.17; OR 3.80, 95% CI 0.86 to 16.75, respectively). Conclusions:These results demonstrated that sarcopenic obesity was independently associated with NAFLD and liver fibrosis and increased the risk of NAFLD and liver fibrosis more than obesity or sarcopenia alone.
Background/AimsFood retention, which is a characteristic observed in patients with achalasia, can interfere with peroral endoscopic myotomy (POEM). However, there is no established guideline for esophageal preparation for POEM. A previous study has shown that drinking warm water may reduce the lower esophageal sphincter pressure in patients with achalasia. This study aims to evaluate the possibility of proper preparation of POEM by instructing the patient to drink warm water. MethodsThe warm water preparation was performed in 29 patients with achalasia who underwent POEM. The patients drank 1 L of warm water (60 o C) the night before POEM. We evaluated the esophageal clearness and determined the preparation quality. Twentynine patients were prospectively recruited and compared to control group. The control cohort comprised achalasia patients whose endoscopic image was available from the achalasia database of our institution. A 1:2 propensity score-matched control cohort was established from the database of achalasia subjects (n = 155) to compare the outcome of the preparation. ResultsIn the warm water preparation group, only 1 patient (3.4%) had some solid retention, but it did not interfere with the POEM procedure. The grade of clearness (P = 0.016) and quality of preparation (P < 0.001) were significantly better in the warm water preparation group than in the matched control group. There was no any adverse event at all related to warm water preparation protocol. ConclusionsDrinking warm water dramatically reduces esophageal food retention and significantly improves the quality of esophageal preparation. This simple protocol is quite useful, safe, and cost-effective in the preparation of achalasia patients for POEM.
There are various methods for treating advanced hepatocellular carcinoma with portal vein invasion, such as systemic chemotherapy, transarterial chemoembolization, transarterial radioembolization, and concurrent chemoradiotherapy. These methods have similar clinical efficacy but are designed with a palliative aim. Herein, we report a case that experienced complete remission through “associating liver partition and portal vein ligation for staged hepatectomy (ALPPS)” after concurrent chemoradiotherapy and hepatic artery infusion chemotherapy. In this patient, concurrent chemoradiotherapy and hepatic artery infusion chemotherapy induced substantial tumor shrinkage, and hypertrophy of the nontumor liver was sufficiently induced by portal vein ligation (stage 1 surgery) followed by curative resection (stage 2 surgery). Using this approach, long-term survival with no evidence of recurrence was achieved at 16 months. Therefore, the optimal use of ALPPS requires sufficient consideration in cases of significant hepatocellular carcinoma shrinkage for curative purposes.
HBeAg seroconversion is an important treatment endpoint. We aimed to identify predictors of seroconversion using serum HBsAg and hepatitis B core-related antigen (HBcrAg) in HBeAg-positive patients treated with nucleos(t)ide analogs (NAs). Data and samples from 70 HBeAg-positive patients treated with entecavir or tenofovir between January 2007 and December 2017 were retrospectively analysed. The mean follow-up period was 11 years. The predictive power for HBeAg seroconversion of HBcrAg levels at baseline and 2 years after antiviral therapy was determined using receiver operating curve analysis. Twenty-one patients (30%) achieved HBeAg seroconversion at a mean of 28 (range, 12-84) months after antiviral treatment. The median baseline HBcrAg and HBsAg levels were 6.9(5.7-7.0) vs. 5.8(5.5-6.5) log 10 U/mL (p = .006), 4.9(4.5-5.1) vs. 4.5(4.1-5.0) log 10 IU/mL (p = .044) in the no seroconversion group and seroconversion group, respectively. In the multivariate analysis, the serum HBcrAg levels at baseline and 2 years after antiviral therapy were predictive factors for HBeAg seroconversion ([HR]; 0.326; [CI], 0.111-0.958; p = .042 and HR, 0.4555; CI, 0.211-0.984; p = .045). HBcrAg levels≤6.5log 10 U/mL at baseline and ≤5.3log 10 U/ mL at 2 years after antiviral therapy had sensitivities of 53.1% and 69.8%, specificities of 95.2% and 70.6%, positive predictive values of 82.6% and 50.0%, and negative predictive values of 82.6% and 84.5%, respectively, with AUROCs of 0.712 (95%CI, 0.596-0.830) and 0.745 (95%CI, 0.599-0.891) for predicting HBeAg seroconversion. In chronic hepatitis B patients treated with NAs, HBcrAg levels≤6.5log 10 U/mL at baseline and ≤5.3log 10 U/mL at 2 years after antiviral therapy were useful predictive factors of HBeAg seroconversion.
