RESUMO

BACKGROUND: The prognostic performance of the albumin-bilirubin (ALBI) grade in hepatocellular carcinoma (HCC) as an objective method of assessing liver function was investigated. METHODS: Data from 2099 patients with HCC in Korea were collected and analyzed retrospectively. The discriminative performance of ALBI grade was compared with Child-Pugh (C-P) grade for different stages or treatments. RESULTS: The median follow up duration was 16.2 months (range: 1.0-124.9). The median survival times were 49.7 months for C-P grade A (65.8%), 12.4 months for C-P grade B (25.5%), and 4.2 months for C-P grade C (8.6%) (P < 0.001). The median survival times were 84.2 months for ALBI grade 1 (32.8%), 25.5 months for ALBI grade 2 (53.5%), and 7.7 months for ALBI grade 3 (13.7%) (P < 0.001). In early UICC stages, ALBI grade showed better discriminative performance than C-P grade. In curative treatments, ALBI grade also showed better discriminative performance than C-P grade (Harrell's C: 0.624 (C-P grade) vs 0.667 [ALBI grade]). CONCLUSIONS: ALBI grade provided better prognostic performance in survival analysis and better distribution of the grades than C-P grade in HCC, suggesting that ALBI grade could be a good alternative grading system for liver function in patients with HCC.

RESUMO

OBJECTIVES: Propranolol has been used as prophylaxis for variceal bleeding in patients with cirrhosis. More recent data suggest that carvedilol may be more effective for reducing the hepatic venous pressure gradient (HVPG) than propranolol. The primary aim of this study was to evaluate the hemodynamic response to carvedilol compared with propranolol. METHODS: A total of 110 patients with a baseline HVPG value >12 mm Hg were allocated randomly to receive either carvedilol or propranolol. The HVPG measurement was repeated after 6 weeks of daily medication. The primary end point was a ≥20% fall in HVPG compared with baseline or <12 mm Hg. RESULTS: The difference in the proportion of responders in the carvedilol (49.1%) vs. propranolol (30.9%) groups did not reach statistical significance in the intention-to-treat analysis (P=0.08). However, among patients with a model for end-stage liver disease (MELD) score ≥15, carvedilol resulted in a significantly greater response than that of propranolol (7/12, 58.3% vs. 0/10, 0%; P=0.005). Similarly, carvedilol was superior to propranolol in patients with Child-Pugh score ≥9 (46.2 vs. 0%; P=0.046). The presence of ascites also had a significant influence on the response rate (51.5 vs. 24.2%; P=0.042). A MELD score ≥15 was the only significant predictor of response among these post hoc groups after adjusting for multiple comparisons (P=0.005). Severe adverse events were higher in the carvedilol group although drug-associated adverse events were not different. CONCLUSIONS: Overall, carvedilol offered no clear advantage over propranolol but it may be more effective in advanced cirrhotic patients with a MELD score≥15 in reducing the portal pressure gradient. However, this potential benefit may come with a cost of increased risk of side-effects and outcome data over a longer term is needed to understand the relative risk benefit.

RESUMO

Hepatic stellate cells (HSC) and liver endothelial cells (LEC) migrate to sites of injury and perpetuate alcohol-induced liver injury. High-mobility group box 1 (HMGB1) is a protein released from the nucleus of injured cells that has been implicated as a proinflammatory mediator. We hypothesized that HMGB1 may be released from ethanol-stimulated liver parenchymal cells and contribute to HSC and LEC recruitment. Ethanol stimulation of rat hepatocytes and HepG2 cells resulted in translocation of HMGB1 from the nucleus as assessed by Western blot. HMGB1 protein levels were increased in the supernatant of ethanol-treated hepatocytes compared with vehicle-treated cells. Migration of both HSC and LEC was increased in response to conditioned medium for ethanol-stimulated hepatocytes (CMEtOH) compared with vehicle-stimulated hepatocytes (CMVEH) (P < 0.05). However, the effect of CMEtOH on migration was almost entirely reversed by treatment with HMGB1-neutralizing antibody or when HepG2 cells were pretransfected with HMGB1-siRNA compared with control siRNA-transfected HepG2 cells (P < 0.05). Recombinant HMGB1 (100 ng/ml) also stimulated migration of HSC and LEC compared with vehicle stimulation (P < 0.05 for both HSC and LEC). HMGB1 stimulation of HSC increased the phosphorylation of Src and Erk and HMGB1-induced HSC migration was blocked by the Src inhibitor PP2 and the Erk inhibitor U0126. Hepatocytes release HMGB1 in response to ethanol with subsequent recruitment of HSC and LEC. This pathway has implications for HSC and LEC recruitment to sites of ethanol-induced liver injury.

RESUMO

BACKGROUND: Hand-foot skin reaction (HFSR) is the most common adverse event during sorafenib treatment in patients with hepatocellular carcinoma (HCC). In the present study, we aimed to investigate the role of urea cream in the prevention of HFSR or amelioration of HFSR severity. PATIENTS AND METHODS: Patients with HCC were treated with either placebo cream or urea cream for 12 weeks concomitantly with sorafenib treatment. HFSR development, the Hand-Foot Skin Reaction and Quality of Life (HF-QoL) questionnaire score, and adverse events were assessed at 2, 4, 8 and 12 weeks. RESULTS: Of the 288 patients, 247 patients, with 117 patients in the placebo control group and 130 patients in the urea cream group, were analysed. The urea cream group showed a trend towards a lower cumulative incidence of any-grade HFSR (log-rank, P = 0.247) and severe HFSR of grade II or higher (log-rank, P = 0.394) without statistical significance. In the incidence by time point, the incidence of severe HFSR of grade II or higher was significantly lower in the urea cream group than in the placebo control group at 2 weeks (13.8% versus 23.9%, P = 0.042). The urea cream group showed a significantly better HF-QoL questionnaire score than the placebo control group (11.8 versus 19.7, P = 0.014) at 12 weeks. CONCLUSIONS: Treatment with urea cream showed a lower incidence of severe sorafenib-induced HFSR at 2 weeks and reduced the tendency of HFSR development in HCC patients. Therefore, treatment with urea cream may be considered for prophylaxis or improvement of HFSR grade in HCC patients treated with sorafenib. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03212625).

RESUMO

BACKGROUND AND AIMS: This study was performed to evaluate the treatment efficacy of endoscopic variceal obturation (EVO) in patients with gastric variceal bleeding (GVB) according to the type of varices. PATIENTS AND METHODS: All patients who were treated with EVO for bleeding from gastric varices (GVs) were included. Patients with a previous history of endoscopic treatment for GVB and those with accompanying portal vein invasion by hepatocellular carcinoma or other malignancy were excluded. RESULTS: Ninety-one patients with GVB were included. Mean age was 59.4±12.4 years and 72 (79.1%) patients were men. The types of varices were gastroesophageal varices (GOV) type 1 (GOV1), GOV2, and isolated gastric varices type 1 (IGV1) in 30 (33.3%), 35 (38.5%), and 26 (28.6%) patients, respectively. Hemostasis and GV obliteration were achieved in 88 (96.7%) and 81 (89.0%) patients, respectively. Among 81 patients with GV obliteration, GV recurred in 26 (32.1%) patients. The GV recurrence rate was significantly lower in patients with GOV1 than in those with GOV2 (P=0.007), while it was comparable between patients with GOV1 and IGV1 (P=0.111) and between patients with GOV2 and IGV1 (P=0.278). Variceal rebleeding occurred in 11 (13.6%) patients. GVB recurrence rate was significantly higher in patients with GOV2 than in those with GOV1 (P=0.034) and IGV1 (P=0.018), while it was comparable between patients with GOV1 and IGV1 (P=0.623). Mortality rate was comparable among the three groups. CONCLUSIONS: EVO was very effective in patients with GVB. GV recurrence and GV rebleeding were significantly lower in patients with GOV1 than in those with GOV2.

RESUMO

BACKGROUND AND AIM: A small proportion of chronic hepatitis B patients have persistently detectable serum hepatitis B virus (HBV) DNA despite lamivudine therapy. The incidence and clinical outcomes of patients who persistently have detectable serum HBV-DNA during lamivudine therapy was investigated. METHOD: We enrolled 221 chronic hepatitis B patients who underwent lamivudine therapy for more than 6 months. Among them, 180 were HBeAg positive. Serum HBV-DNA, HBeAg, anti-HBe and alanine aminotransferase (ALT) levels were serially monitored. The study groups were defined, using a hybridization assay, as patients with reductions in serum HBV-DNA below the detectable level (group I) or patients with persistently detectable serum HBV-DNA (group II) during the initial 6 months of lamivudine therapy. RESULTS: The incidence of patients who had persistently detectable HBV-DNA was 7.7%. After the first year, the rates of viral breakthrough, HBeAg loss and serum ALT normalization of group I versus group II were 21% versus 63%, 38% versus 0%, and 71% versus 28%, respectively (P < 0.001). The log(10) reduction of serum HBV-DNA at 6 months was -4.58 log(10) for group I and -1.97 log(10) for group II (P < 0.001, bDNA assay). There were no pretreatment lamivudine-resistant mutants in group II. CONCLUSION: Lamivudine had little effect on serum HBV-DNA suppression, viral breakthrough suppression and rate of HBeAg loss and ALT normalization in chronic hepatitis B patients with persistently detectable serum HBV-DNA during the initial 6 months of therapy. Early termination of lamivudine therapy is advocated for these patients.
