Severe inflammation in the background liver cirrhosis correlates with the development of poorly differentiated HCC in HCV-associated liver cirrhosis

Real-World Risk and Outcome of Liver Cirrhosis in Patients with Hyperlipidemia Treated with Red Yeast Rice: A Retrospective Cohort Study

Objective

Sustained hyperlipidemia contributes to fatty liver and liver cirrhosis. Red yeast rice (RYR) effectively improved the lipid profile; however, the effects of RYR on the risk of incident liver cirrhosis remain to be elucidated. We aimed to evaluate the beneficial effects of RYR use on the risk and outcome of liver cirrhosis.

Patients and methods

We identified 156,587 adults who had newly diagnosed hyperlipidemia in 2010-2016 from health insurance data in this retrospective cohort study. Using propensity score matching, we selected 34,367 patients who used RYR and 34,367 patients who used lovastatin. Events of incident liver cirrhosis that occurred in the two cohorts during the follow-up period of 2010-2019 were identified. We calculated adjusted hazard ratios (HRs) and 95% confidence intervals (Cis) for liver cirrhosis risk associated with RYR use in the multiple Cox proportional hazard model.

Results

Compared with patients who used lovastatin, patients who used RYR had a decreased risk of liver cirrhosis (HR 0.60, 95% CI 0.57-0.63), and this association was significant in various subgroups. A biological gradient relationship between the frequency of RYR use and decreased liver cirrhosis was observed (p for trend < 0.0001). Reduced postcirrhosis jaundice (HR 0.56, 95% CI 0.43-0.72), ascites (HR 0.37, 95% CI 0.28-0.50), hepatic coma (HR 0.36, 95% CI 0.26-0.50), and mortality (HR 0.48, 95% CI 0.38-0.61) were also associated with RYR use.

Conclusion

We demonstrated the beneficial effects of RYR use on the risk and outcome of liver cirrhosis; however, the lack of compliance data should be considered. However, our study did not infer causality or claim the superiority of RYR over lovastatin.

Elevated preoperative aspartate aminotransferase to lymphocyte ratio index as an independent prognostic factor for patients with hepatocellular carcinoma after hepatic resection

Few studies have elucidated the relationship between preoperative aspartate aminotransferase (AST) to lymphocyte ratio and high incidence of hepatocellular carcinoma (HCC). In search of a simple non-invasive prognostic marker, we investigated the prognostic significance of AST to lymphocyte ratio index (ALRI) in HCC. We reviewed retrospectively clinical parameters of 371 HCC patients who were treated with hepatectomy. Receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off value of preoperative ALRI. The predictive value of preoperative ALRI in HCC was evaluated by univariate and multivariate analyses using Cox proportional hazards regression modeling, and the survival probability of HCC patients was acquired by the Kaplan-Meier plots. In addition, stratified analysis was used to investigate the impact of preoperative ALRI on survival in different HCC subgroups. The results showed that preoperative ALRI was closely correlated with age (p = 0.007), median size (p = 0.004), clinical tumor-node-metastasis (TNM) stage (p < 0.001), and portal vein tumor thrombosis (PVTT) (p < 0.001). Survival analysis indicated that HCC patients with preoperative ALRI > 25.2 have a poorer disease-free survival (DFS) and overall survival (OS) after tumor resection. Multivariate analysis further identified preoperative ALRI > 25.2 (p = 0.002), III-IV of TNM stage (p = 0.011), PVTT (p = 0.035), size of tumor > 5 cm (p < 0.001) as independent risk factors of DFS; and preoperative ALRI > 25.2 (p = 0.001), III-IV of TNM stage (p = 0.005), PVTT (p = 0.012), size of tumor > 5 cm (p < 0.001), recurrence (p < 0.001) as independent prognostic factors for OS in HCC patients. Additionally, preoperative ALRI also showed different prognostic value in various subgroups of HCC. Elevated preoperative ALRI as a noninvasive, simple, and easily assessable parameter is an independent effective predictor of prognosis for patients with HCC.

Hypersplenism is correlated with increased risk of hepatocellular carcinoma in patients with post-hepatitis cirrhosis

Several risk factors exist for hepatocellular carcinoma in patients with post-hepatitis cirrhosis (PHC), including hypersplenism. Splenectomy is a common but controversial procedure in the management of hypersplenism, but its impact on hepatocellular carcinoma (HCC) remains uncertain. We conducted a hospital-based study of PHC patients to identify potential risk factors, including a history of splenectomy, which has been associated with progression from PHC to HCC. From 2002 to 2012, 2678 patients developed hypersplenism secondary to PHC. Of these patients, 828 developed HCC and 1850 did not. Potential risk factors of HCC were determined by univariate and multivariate analyses to exclude confounding variables. Odds ratios (ORs) and 95 % confidence intervals (95 % CIs) were determined for each factor. Many factors, such as liver function, platelet (PLT) counts, Child-Pugh class, and history of hepatitis, were associated with progression to HCC. PHC patients with hypersplenism who displayed elevated levels of alanine transaminase (ALT), aspartate transaminase (AST), γ-glutamyltransferase (GGT), ALK, phosphatase, and prolonged prothrombin time (PT) had a significantly increased risk of HCC. However, the patients who had splenectomy showed better liver function test results and less progression to HCC. In patients with PHC and hypersplenism, abnormal levels of ALT, AST, ALP, and GGT and prolonged PT are risk factors of HCC. Splenectomy, as the intervention method of hypersplenism, is performed less frequently in patients who developed HCC than in patients who did not develop HCC. Therefore, splenectomy may act as an independent factor that is significantly associated with HCC development.
