RESUMO
BACKGROUND: Vitamin D (VD) is important in hepatic fibrogenesis in animal models and human studies. VD deficiency is associated with liver fibrosis progression. Metabolic dysfunction of the liver, as an intermediate organ for VD metabolism, contributes partly to this deficiency. We hypothesized that improving hepatic fibrosis and inflammation in chronic hepatitis C (CHC) patients after eradication with direct-acting antivirals (DAA) would increase 25-hydroxyVD [25(OH)VD] levels. METHODS: Eighty CHC patients (17 chronic hepatitis, and 63 cirrhosis) were enrolled. Baseline characteristics, hepatitis C viral load (VL), genotypes, liver enzymes and liver stiffness measurements (LSM) were assessed at baseline. Blood samples for 25(OH)VD and the procollagen type III N-terminal peptide (P3NP) were collected at baseline, 24 and 48 weeks. LSMs were re-evaluated at 48 weeks. Serum 25(OH)VD levels < 30 ng/mL were defined as VD insufficiency/deficiency. Paired t-tests were used for statistical analyses. RESULTS: Among 80 patients, the mean age was 57.7 ± 10.5 years, and 52.5% were men. The mean VL was 6.1 ± 0.7 logIU/mL with genotype 1 predominance (55%). All patients achieved sustained virological response. The alanine aminotransferase levels decreased from 79.9 ± 53.3 U/L at baseline to 25.7 ± 17.2 and 22.3 ± 11.0 U/L at 24 and 48 weeks, respectively (p < 0.001). The mean LSM decreased from 19.2 ± 15.3 to 11.7 ± 8.0 kPa at 48 weeks (p < 0.001). The P3NP levels decreased from 43.6 ± 22.0 ng/mL before treatment to 35.7 ± 21.1 and 29.4 ± 15.0 ng/mL at 24 and 48 weeks, respectively (p < 0.001). The proportions of VD insufficiency/deficiency were 72.5%, 91.3%, and 86.5% at baseline, 24 and 48 weeks, respectively. The 25(OH)VD levels decreased from 26.3 ± 10.7 ng/mL at baseline to 20.8 ± 8.1 and 20.8 ± 8.5 ng/mL at 24 and 48 weeks, respectively (p < 0.001). CONCLUSIONS: Curative treatment with DAA attenuated the liver stiffness and inflammation but did not improve VD levels. Over 80% of patients remained VD insufficient/deficient. Whether VD replacement during and after DAA therapy can improve hepatic fibrosis remains unclear.

BACKGROUND: We aimed to examine the burden of intrahepatic cholangiocarcinoma (ICC) in Thailand and identify the prognostic factors for all-causes of death. METHODS: We conducted a population-based study of ICC patients admitted during 2009-2013 using the Nationwide Hospital Admission Database, the National Health Security Office (NHSO). There was an average of 1,051,146 patients/year with diagnosis of gastrointestinal diseases (GI). All patients with a diagnosis of ICC (ICD10- C221) were included from a total of 72,479 admissions from 858 hospitals. The surgical resection procedures such as the radical pancreaticoduodenectomy, subtotal and partial hepatectomy were analyzed. Data for all patients were censored 1 year post-study or death, whichever came first. RESULTS: A total of 34,325 patients with ICC during a 5-year study period (on average, 6865 patients/year, with the incidence rate of 14.6 per 100,000 population, per year. The ICC patients had a mean age of 63.8+/-11.6 years and 63% were males. The mean length of hospital stay was 6.4+/-7.3 days with a mean+/-SD cost of hospitalization of $595+/-$1160 USD per admission. There were 659 patients (1.9%) underwent surgical resection. The overall survival of ICC patients with surgery was significantly better than those patients without surgery. Hazard ratio of death for patients without surgery was 2.5 (95% CI of 2.3-2.7). Approximately 14% of the ICC patients died during hospitalization. The median overall survival of all patients after the first admission was 53 +/-0.6 days. From the multivariate analysis, factors related to all-causes of death were: patients' age >60 years (OR = 1.2, 95% CI; 1.1-1.3), length of hospital stay of >7 days (OR = 1.1, 95% CI; 1.02-1.2), male (OR = 1.3, 95% CI; 1.2-1.4), living in the northern part of Thailand (OR = 1.5, 95% CI; 1.3-1.8) and presence of complications during admission (OR = 1.3, 95% CI; 1.1-1.5). CONCLUSION: The disease burden of patients with ICC in Thailand is significant with the incidence rate of 14.6 per 100,000 population, per year during 2009-2013 and showed high mortality rate of 14%.

BACKGROUND: Replacement of vitamin D (VD) among patients with chronic hepatitis C (CHC) before viral eradication has demonstrated a protective effect on serum markers associated with hepatic fibrogenesis. We therefore hypothesized that VD may facilitate further fibrosis amelioration following curative treatment with direct-acting antivirals (DAA). METHODS: This study was a randomized, double-blind, placebo-controlled trial conducted between February 2018 and August 2018. Patients with CHC and VD deficiency were randomized in a 1:1 ratio to either receive ergicalciferol or placebo over 6 weeks. Biochemical analysis indicators, including 25-hydroxyvitamin D (25(OH)D), fibrogenic markers [(transforming growth factor beta 1 (TGF-ß1) and tissue inhibitors of matrix metalloproteinases 1 (TIMP-1)], and fibrolytic markers [matrix metalloproteinase 9 (MMP-9) and amino terminal type III procollagen peptide (P3NP)], were assessed at baseline and at 6 weeks. Serum 25(OH)D was analyzed by a chemiluminescence immunoassay. Serum hepatic fibrogenesis markers were measured using a quantitative sandwich enzyme-linked immunosorbent assay. RESULTS: Seventy-five patients with CHC and VD deficiency were randomly assigned to VD (n = 37) and placebo (n = 38) groups. At the end of the study, the mean serum 25(OH)D level had risen to a normal level in the VD group, but was still deficient in the placebo group (41.8 ± 9.1 vs. 18.1 ± 4.6 ng/mL, p < 0.001). Upon restoration of the VD level, there were no significant mean differences in the change from baseline for TGF-ß1 (-0.6 ng/mL (95% confidence interval (95% CI) [-2.8-1.7]), p = 0.63), TIMP-1 (-5.5 ng/mL (95% CI [-26.4 -15.3]), p = 0.60), MMP-9 (122.9 ng/mL (95% CI [-69.0 -314.8]), p = 0.21), and P3NP (-0.1 ng/mL (95% CI [-2.4 -2.2]), p = 0.92) between the VD and placebo groups. CONCLUSION: Short-term VD supplementation after DAA treatment in patients with CHC does not improve serum fibrogenesis markers and may not expedite the residual liver fibrosis healing process. Future studies are warranted to evaluate the long-term effect of VD supplementation on hepatic fibrosis regression.
RESUMO
BACKGROUND/AIM: The global problems of chronic liver disease and non-alcoholic fatty liver disease (NAFLD) are increasing. We examined the prevalence of NAFLD and significant liver stiffness in an asymptomatic population and identified the predictors of significant fibrosis in NAFLD. METHOD: We prospectively enrolled Thai subjects, aged 18-80 years, from four regions (Bangkok, Central, North, South) of Thailand from March 2013 to November 2016. All participants underwent controlled attenuation parameter (CAP) measurement for liver fat quantification and transient elastography (TE) for liver stiffness measurement (LSM). NAFLD was defined as liver fat ≥10% (CAP ≥ 306 dB/m). Of 1145 participants, 782 (68.3%) were eligible for analysis. RESULT: The mean age ± standard deviation (SD) was 53.1 ± 4.6 years, and 71.6% were female. The mean ± SD values of CAP and LSM of the overall cohort were 241.9 ± 61.4 dB/m and 5.5 ± 3.8 kPa, respectively. The prevalence of NAFLD was 18.0%, whereas 5.4% of the cohort had nonobese NAFLD (BMI < 25 kg/m2), and 2.8% had lean NAFLD (BMI < 23 kg/m2). The prevalence of significant liver fibrosis (≥F2) in NAFLD subjects was 18.4%. On multivariate analysis, the degree of significant fibrosis in NAFLD was significantly associated with male gender and a history of dyslipidemia. CONCLUSION: NAFLD with significant fibrosis (≥F2) is prevalent in asymptomatic populations. The predictors of significant fibrosis in NAFLD were male gender and dyslipidemia. Screening for NAFLD using CAP/TE in asymptomatic populations should be considered in hospitals with available facilities.
RESUMO
BACKGROUND AND AIM: A nonselective B-blocker (NSBB) is recommended for primary prophylaxis of variceal bleeding. The impact of treatment with NSBB on modulating transient elastography (TE) has not been reported. The aim of the study is to investigate the effect of NSBB treatment on TE in early cirrhotic patients. METHODS: In this prospective study, we enrolled all early cirrhotic patients who underwent esophagogastroduodenoscopy (EGD) and showed small esophageal varices (EV) at our institute for a period of 1 year. The TE and heart rate (HR) of all participants were measured before and 3 months after receiving NSBB. RESULTS: Thirty-nine patients receiving propanolol for 3 months were analyzed. There were 16 patients in the HR responder group (41%) and 23 patients in the HR nonresponder group (59%). The reduction of TE was preferably found in the HR responder group compared with the HR nonresponder group, in which mean changes in TE were -5.6 and -0.7 kPa, respectively (P = 0.23). In addition, we categorized the patients using their TE responses. Twenty-five patients (64.1%) showed reduced TE during the follow-up period, in which the mean TE value change was -2.94 kPa. Using correlation analysis, TE and HR responses were insignificantly correlated (r = 0.23, P = 0.15). CONCLUSION: The NSBB administered for 3 months mainly improved TE value in early cirrhotic patients even though the changes of HR and TE did not correlate. Further study is needed to confirm whether the monitoring of TE change may be a better predictor for pharmacological response than the HR response.
