Purpose: To determine the frequency and socio‐demographic/clinical correlates of insomnia in patients with chronic hepatitis B, hepatitis B virus (HBV)‐related liver failure, and cirrhosis. Design and Methods: Up to 120 patients with HBV‐related diseases and 40 matched healthy controls were recruited. Depressive and anxiety symptoms, early, middle, and late insomnia were measured. Findings: The frequency of ≥1 type of insomnia was 64.2% in patients and 35.0% in controls; frequencies of early, middle, and late insomnia in patients were 39.2%, 42.5%, and 48.3%, respectively, compared to 22.5%, 10.0%, and 25.0% in controls. Urban residency was independently associated with less insomnia of any type, accounting for 22.6% of the variance. Practice Implications: A considerable proportion of patients with HBV‐related diseases suffer from insomnia that warrants more attention in clinical practice. [ABSTRACT FROM AUTHOR]

Background: Little is known on the cost-effectiveness of novel regimens for hepatitis C virus (HCV) compared with standard-of-care with pegylated interferon (pegIFN) and ribavirin (RBV) therapy in developing countries. We evaluated cost-effectiveness of sofosbuvir/ledipasvir for 12 weeks compared with a 48-week pegIFN-RBV regimen in Chinese patients with genotype 1b HCV infection by economic regions. Methods: A decision analytic Markov model was developed to estimate quality-adjusted-life-years, lifetime cost of HCV infection and incremental cost-effectiveness ratios (ICERs). SVR rates and direct medical costs were obtained from real-world data. Parameter uncertainty was assessed by one-way and probabilistic sensitivity analyses. Threshold analysis was conducted to estimate the price which can make the regimen cost-effective and affordable. Results: Sofosbuvir/ledipasvir was cost-effective in treatment-experienced patients with an ICER of US$21,612. It varied by economic regions. The probability of cost-effectiveness was 18% and 47% for treatment-naive and experienced patients, and it ranged from 15% in treatment-naïve patients in Central-China to 64% in treatment-experienced patients in Eastern-China. The price of 12-week sofosbuvir/ledipasvir treatment needs to be reduced by at least 81% to US$18,185 to make the regimen cost-effective in all patients at WTP of one time GDP per capita. The price has to be US$105 to make the regimen affordable in average patients in China. Conclusion: Sofosbuvir/ledipasvir regimen is not cost-effective in most Chinese patients with genotype 1b HCV infection. The results vary by economic regions. Drug price of sofosbuvir/ledipasvir needs to be substantially reduced when entering the market in China to ensure the widest accessibility. [ABSTRACT FROM AUTHOR]

Summary Objective To explore the relation between serum sphingolipids and hepatic injury in chronic HBV infection. Methods A cohort of participants including 48 healthy persons, 103 chronic HBV-infected patients containing chronic hepatitis B (CHB) and HBV-related cirrhosis were included. High performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) was performed to detect serum sphingolipids. The serological indicators were detected and quantified. The valid liver biopsy specimens were acquired from twenty five CHB. Results Twenty four serum sphingolipids were detected. There were eighteen sphingolipids showing significant differences between the healthy control and chronic HBV infection groups. In patients with chronic HBV infection, fourteen sphingolipids differed significantly between CHB and HBV-related cirrhosis. Among sphingolipids with a significant difference in both HBV infection vs healthy control and CHB vs cirrhosis, seven sphingolipids were independently related to the presence of cirrhosis. SM(d18:1/24:0), a sphingomyelin (SM) compound, was found to have a negative correlation with model for end-stage liver disease (MELD) score. Additionally, SM(d18:1/24:0) was demonstrated to have a correlation with inflammation grades by liver biopsy in CHB patients. Conclusions Serum sphingolipids have close relation with hepatic injury in chronic HBV infection, especially that SM(d18:1/24:0) might be a potential serum biomarker. [ABSTRACT FROM AUTHOR]

Accurate estimation of hepatic necroinflammation caused by chronic hepatitis C (CHC) is crucial for prediction of prognosis and design of therapeutic strategy, which is particularly true for CHC patients with normal alanine aminotransferase (ALT) level. Recent studies have shown that sphingolipids have a close relationship with hepatitis C virus infection. The present study aimed to identify plasma sphingolipids related to hepatic necroinflammation. We included 120 treatment-naïve CHC patients and 64/120 had normal ALT levels (<40 U/L). CHC patients who underwent liver biopsies were subjected to Scheuer scoring analysis for scope of hepatic inflammation. Plasma sphingolipids were detected by high-performance liquid chromatography tandem mass spectrometry. Our results showed 44 plasma sphingolipids were detected altogether. Of all detected sphingolipids, hexosylceramide (HexCer) (d18∶1/22∶0) and HexCer (d18∶1/24∶0) showed a significant difference among G0/G1, G2, and G3/G4 (P<0.05). For identifying hepatic necroinflammation (G≥2), after adjusting other factors, the odds ratio (OR) of HexCer (d18∶1/22∶0) reached 1.01 (95% confidence interval [CI]: 1.00–1.02). Furthermore, the area under the curve (AUC) of HexCer (d18∶1/22∶0) was 0.7 (P = 0.01) and approached that of ALT (AUC = 0.78). However, in CHC patients with normal ALT, HexCer (d18∶1/22∶0) was an independent factor (OR: 1.02, 95% CI: 1.01–1.03) to identify the hepatic necroinflammation (G≥2). HexCer (d18∶1/22∶0) not only showed the largest AUC (0.78, P = 0.001), but also exhibited the highest specificity of all indicators. These results indicate that plasma HexCer (d18∶1/22∶0) is a potential indicator to distinguish hepatic necroinflammation in CHC patients. For CHC with normal ALT, the ability of HexCer (d18∶1/22∶0) to distinguish hepatic necroinflammation might be superior to conventional serum indicators. [ABSTRACT FROM AUTHOR]
