N is shown in Figure 1. Ten healthy volunteers between the ages of 18 and 50 were enrolled and assigned to the control group. The baseline assessments of study subjects from these two groups are shown in Table 1. All five patients with ACHBLF were male and 80 were HBeAg positive. Their mean HBV DNA levels were 6.2762.24 log10 IU/mL and mean MELD-Na scores were 19.2263.8 at the baseline. All were admitted and observed with supportive care in the hospital and achieved remission without further intervention within 12 weeks. In addition, two female and eight male healthy volunteers were prospectively enrolled as controls. The mean ages of subjects in the two study groups were well matched without statistical significance.Measurement of LPS and Parameters for Disease SeverityThe primary measurement of this study was the followings: 1) measured serum LPS levels in three disease phases of ACHBLF and compared to those in the control group; 2) evaluated dynamic changes in LPS levels in ACHBLF by comparing the distribution pattern of LPS levels throughout all phases of ACHBLF. The secondary measurement was to assess the association between LPS levels and the disease severity indicated by MELD-Na scores. In addition to MELD-Na scores, serum total bilirubin levels were also selected as the main markers for the disease severity in this study. Other K162 clinical parameters were also assessed, which included aspartate aminotransferase (AST), and alanine aminotransferase (ALT) albumin, creatinine (automatic biochemical analyzer, Olympus, Japan), prothrombin time (automatic hemostasis/ thrombosis analyzer, STA compact). All laboratory tests for patients in our center were performed in the hospital central laboratory. HBV serologies were MedChemExpress Licochalcone-A tested by either CMIA (Abbott I 2000, 18055761 USA) or ECL kits (Roche Laboratories, Germany). All serum samples for HBV DNA were tested by real-time quantitative PCR (Shanghai Kehua Bioengineering Co., 15755315 Ltd., China) with the detection range of 500 copies ? log10 copies/mL. Total bilirubin (TBIL), ALT (ULN = 40 U/L) and other biochemistry markers were tested by a Hitachi 7600 fully-automatic biochemical (Hitachi Co. Ltd., Tokyo, Japan). LPS concentrations in plasma were measured with the Limulus Amebocyte Lysate (LAL) test (Xiamen Houshiji, Ltd., Xiamen, China) according to the manufacturer’s instructions. All the materials used were pyrogen free and LPS in the test samples was calculated by comparison to a standard curve. All samples were tested in duplicate and read at 450 nm for LPS in a Thermomax microplate reader (Molecular Devices, Sunnyvale, CA).2. LPS Levels in Different Phases of ACHLFIn the ACHBLF group, the mean duration of disease progression from the onset of the disease to the peak phase was 31.2462.77 days. The mean duration of the peak phase was 6.0061.00 days. The mean duration of remission phase was 31.60615.24 days. Significantly higher levels of LPS were observed in the peak phase compared to those in progression phase (0.096060.0680 vs. 0.016860.0101, p = 0.008) or those in remission phase (0.096060.0680 vs. 0.024960.0365, p = 0.021). When compared to the control group, LPS levels during the peak phase in ACHBLF were also significantly higher (0.020160.0146 vs. 0.096060.0680, P = 0.007). However, there were no statistically significant differences in LPS levels between controls and ACHBLF patients in progression phase (0.016860.0101 vs. 0.020160.0146, p = 0.618) or in remission phase (0.024960.0365 vs. 0.020160.0.N is shown in Figure 1.
