Abstract
OBJECTIVE To identify nonalcoholic steatohepatitis (NASH) and liver stiffness in Mexican subjects with different body mass index (BMI). METHODS A cross-sectional study was conducted in 505 adults. Risk for NASH was defined as the presence of one or more of the following biochemical and metabolic parameters (BMPs): fasting glucose ≥100 mg/dl, triglycerides (TG) ≥150 mg/dl, homeostatic model assessment of insulin resistance (HOMA-IR) ≥2.5, aspartate aminotransferase (AST) >54 IU/L and alanine aminotransferase (ALT) >42 IU/L. Body mass index measurement and nutritional assessment were performed by standard procedures. Liver fibrosis stage was determined by liver stiffness measurement using transitional elastography (TE) or by liver biopsy (LB). RESULTS Risk for NASH was 57% (290/505). Most BMPs values incremented by BMI category. Among 171 at-risk patients, 106 subjects were evaluated by TE and 65 subjects by LB. Abnormal liver stiffness (≥6.0 kPa) was prevalent in 54% (57/106) of the cases, whereas by LB, 91% (59/65) of patients with obesity had NASH and liver fibrosis. Furthermore, liver fibrosis was prevalent in 46% (6/13) in normal weight individuals, whereas 4.6% (3/65) of patients with a BMI ≥ 35 kg/m2 showed no histopathological abnormalities. Overall, 67.8% (116/171) of the patients had abnormal liver stiffness or NASH. The normal weight patients with liver damage consumed relatively a higher fat-rich diet compared to the other groups whereas the remaining subgroups shared a similar dietary pattern. CONCLUSION Young patients with overweight and obesity showed a high prevalence of altered BMPs related to abnormal liver stiffness assessed by TE and NASH by LB. Early diagnostic strategies are required to detect the risk for NASH and avoid further liver damage in populations with a rising prevalence of obesity by defining the risk factors involved in the onset and progression of NASH.

Abstract
Hepatitis B virus (HBV) infection may be underestimated among high-risk individuals in regions of low HBs antigenemia. This study aimed to assess HBV serological markers, genotypes, and risk factors in Mexican patients with risk of HBV infection and low socioeconomic status. Demographics, clinical, and risk factor data were collected in patients with HIV (n = 289), HCV (n = 243), deferred blood donors (D-BD) (n = 83), and two native populations, Mixtecos (n = 57) and Purepechas (n = 44). HBV infection was assessed by HBsAg, anti-HBc, and HBV-DNA testing. Overall, patients had low education and very-low income. Totally, HBsAg prevalence was 16.5% (113/684) ranging from 0.7% (HCV) to 37.3% (D-BD), while anti-HBc was 30.2% (207/684). Among 52 sequences, genotypes H (n = 34, 65.4%), G (n = 4, 7.7%), subgenotypes F1b (n = 7, 13.5%), A2 (n = 6, 11.5%), and D4 (n = 1, 1.9%) were detected. Surgeries, sexual promiscuity, and blood transfusions had a differential pattern of distribution. In HCV patients, single (OR = 5.84, 95%Cl 1.91-17.80, P = 0.002), MSM (OR = 4.80, 95%Cl 0.75-30.56, P = 0.097), and IDU (OR = 2.93, 95%CI 1.058-8.09, P = 0.039) were predictors for HBV infection. While IDU (OR = 2.68, 95%CI 1.08-6.61, P = 0.033) and MSM (OR = 2.64, 95%CI 1.39-5.04, P = 0.003) were predictors in HIV patients. In this group, MSM was associated with HBsAg positivity (OR = 3.45, 95%CI 1.48-8.07, P = 0.004) and IDU with anti-HBc positivity (OR = 5.12, 95%CI 2.05-12.77, P < 0.001). In conclusion, testing with a combined approach of three different HBV markers, a high prevalence of HBV infection, a differential distribution of HBV genotypes, including subgenotypes F1b, A2, and D4, as well as risk factors in low-income Mexican risk groups were detected.

Chronic hepatitis B: correlation of abnormal features on T2-weighted imaging and dynamic contrast-enhanced imaging with hepatic histopathology. Radiol Med 2017; 122:807-813. [PMID: 28695452 DOI: 10.1007/s11547-017-0789-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2017] [Accepted: 07/04/2017] [Indexed: 02/07/2023]
Abstract
OBJECTIVES To investigate the correlations between abnormal features on liver magnetic resonance (MR) T2-weighted imaging (T2WI) and dynamic contrast-enhanced (DCE) imaging and the pathological findings in chronic hepatitis B. MATERIALS AND METHODS Sixty-seven patients with chronic hepatitis B and 18 normal controls who were undergone an abdominal MR imaging were analyzed retrospectively. Patchy hyperintensities, linear and reticular hyperintensities in liver and periportal edema on T2WI and abnormal intrahepatic enhancement signals on DCE imaging were noted. The correlations between the abnormal features detected on hepatic T2WI and DCE imaging, and the levels of inflammatory activity and fibrosis were determined. RESULTS Logistic regression analysis showed increased patchy hyperintensities (B = 1.869, P = 0.001) on T2WI and patchy enhancement (B = 1.596, P = 0.004) at the arterial phase along with increased inflammatory activity. However, linear and reticular hyperintensities (B = 2.356, P = 0.000) on T2WI, and meshwork enhancement (B = 2.191, P = 0.000) at the equilibrium phase, all correlated with fibrosis. Moreover, periportal edema mainly correlated with the inflammatory activities (B = 2.635, P = 0.001). CONCLUSIONS In chronic hepatitis B patients, patchy hyperintensities on T2WI, periportal edema, and patchy enhancement at the arterial phase can predict moderate-to-severe inflammatory activities, whereas intrahepatic linear and reticular hyperintensities on T2WI, and meshwork enhancement at the equilibrium phase can predict moderate-to-severe fibrosis.

Abstract
BACKGROUND AND OBJECTIVE Liver cirrhosis is usually detected at the later stages of disease. This study is aimed to detect liver damage in patients with chronic liver disease using transitional elastography (TE) and to assess the biochemical parameters associated with liver damage. METHODS In 578 patients, chronic liver disease based on etiology was diagnosed by clinical and laboratory tests. Liver damage was evaluated with TE (FibroScan®), while its association with biochemical parameters was performed using the logistic regression tests. RESULTS Overall, the main etiologies of liver damage were hepatitis C virus (HCV) (37%), alcoholic liver disease (ALD) (33%) and non-alcoholic steatohepatitis (NASH) (26%). Patients were 40 to 50 years of age. ALD and hepatitis B prevailed in men, whereas HCV and NASH in women. The stages of fibrosis were F0 (n = 121, 21%), F1 (n = 122, 21%), F2 (n = 58, 10%), F3 (n = 46, 8%) and F4 (n = 87, 15%). In patients with liver cirrhosis, ALD (n = 96/217, 45%), HCV (n = 94/217, 43%) and NASH (n = 21/217, 10%) were the leading etiologies. Platelets count (OR=3.31, 95%CI 1.61-6.78), glucose (OR=3.07, 95%CI 1.50-6.26), gamma-glutamyl-transferase (OR=3.60, 95%CI 1.79-7.25), albumin (OR=3.89, 95%CI 1.61-9.36), and total bilirubin (OR=3.93, 95%CI 1.41-10.91) were associated to advanced stages of fibrosis (F3-F4) regardless of etiology. The concordance and positive predictive values of these parameters were higher as compared to other scores. CONCLUSION Asymptomatic liver disease due to HCV, ALD and NASH prevailed in young adults. Advanced liver damage assessed by TE was associated with five biochemical parameters. In conjunction, both methodologies may be useful for the early detection of fibrosis and cirrhosis in Latin America.

Abstract
BACKGROUND Nucleos(t)ide analogs (NUCs) are the standard of care for chronic hepatitis B (CHB). The present analysis aimed to determine the cost effectiveness of NUCs in Chinese healthcare settings. METHODS A Markov model was used to simulate two therapeutic strategies for a hypothetical patient cohort diagnosed with hepatitis B e antigen-positive CHB, unwilling or unable to receive interferon therapy, and about to start treatment with any NUC. The first strategy included NUC monotherapy without sequencing (telbivudine [LDT], entecavir [ETV], tenofovir [TDF], lamivudine [LAM], adefovir dipivoxil [ADV], and combination therapies of either LDT and ADV or LDT and TDF, followed by best supportive care [BSC]). The second strategy included sequential therapies of individual NUCs: LAM → ADV, ADV → LAM, LDT → ADV, and ETV → ADV, followed by BSC. The analysis included two scenarios: with and without costs due to nephrotoxicity. Renal impact was quantified as costs alone, without consideration for quality of life decrements. RESULTS When renal impact was not considered, without treatment sequencing, LDT was cost effective compared with other NUCs. Amongst the strategies with sequencing, LDT → ADV was cost effective. The results were similar when renal impact was considered. However, LDT strategy demonstrated better cost effectiveness. In probabilistic sensitivity analysis, in both scenarios, LDT → ADV sequence was cost effective with 51 % probability even at willingness to pay of $20,000. CONCLUSION Use of LDT, as compared with other NUCs, is cost effective in CHB treatment in Chinese healthcare settings. Considering the detrimental renal impact, overall costs for all treatment options were increased. However, the increase for LDT was comparatively small.

Abstract
The present study was designed to determine the seroprevalence of hepatitis B and C virus (HBV, HCV) infections and risk factors in the Turkish general population. Participants were enrolled from urban and rural areas of the predetermined 23 EUROSTAT NUTS 2 region. A two-stage stratified sampling method was used to select participants from these regions (n = 5460; 50.9% females; mean (SD) age: 40.8 (14.7) years). Sociodemographics, clinical characteristics and risk factors were recorded at home visits. The seropositivity rates for hepatitis B surface antigen (HBsAg), anti-HCV, anti-HBs and anti-HBc total were 4.0%, 1.0%, 31.9% and 30.6%, respectively. Among HBsAg-positive cases, 94.5% were anti-HBe-positive, 70.2% were HBV-DNA-positive and 2.8% were anti-HDV total positive; 99.1% of HBV infections were of genotype D. Close contact with a hepatitis patient (OR 3.24; 95% CI 2.25-4.66; p < 0.001), living in the southeastern region (OR 2.74; 95% CI 1.7-4.45; p < 0.001), male gender (OR 1.77; 95% CI 1.28-2.46; p < 0.001), being married (OR 1.62; 95% CI 1.02-2.57; p 0.038), educational level less than high school (OR 1.53; 95% CI 1.04-2.26; p 0.03), orodental interventions (OR 1.54; 95% CI 1.01-2.35; p 0.047) and a history of non-disposable syringe use (OR 1.4; 95% CI 1.01-1.96; p 0.045) were significant determinants of HBsAg positivity. Age ≥50 years (OR 2; 95% CI 1.09-4.3; p 0.026) was the only significant predictor of anti-HCV positivity. In conclusion, our findings revealed an HBsAg positivity in 4% and anti-HCV positivity in 1% of the adult population and at least one-third of the population has been exposed to HBV infection in Turkey.

Abstract
The purpose of this study was to explore direct economic burden and its influencing factors in patients with hepatitis B virus (HBV) related diseases. Time phasing continuous sampling was used to select patients from August 1, 2012, to December 31, 2012, in 3 county hospitals of 3 model regions in Jiangsu Province, China. A total of 436 outpatients and 196 inpatients were observed. The average direct economic burden of HBV-associated admission was US$107.11 for outpatients, and drug fees accounted for 74%; the burden was US$3193.47 for inpatients, and the direct medical costs accounted for 96%. Multivariate linear regression analysis showed that drug fee, examination fee, and antiviral therapy were influencing factors for outpatients, while hospitalization stay, drug ratio, and patient's age were influencing factors for inpatients. It can be concluded that the direct economic burden of patients with HBV-related diseases was high compared to their household income. Measures should be taken to reduce the economic burden of patients.

Abstract
BACKGROUND AND AIMS Chronic hepatitis B (CHB) disproportionately affects the Asian-American population in the USA. Tenofovir disoproxil fumarate (TDF) has demonstrated potent antiviral activity in clinical trials, but data in Asian-Americans from community studies are lacking. METHODS Adult Asian-American patients with CHB from private medical and community-based practices were prospectively enrolled and treated with open-label TDF 300 mg once daily in a single-arm study for 48 weeks. After Week 48, patients had the option to transition to commercially available CHB therapy. The primary efficacy endpoint was hepatitis B virus (HBV) DNA <400 copies/mL at Week 48. Secondary endpoints were safety and tolerability, serologic and biochemical responses, liver fibrosis by FibroTest, and the development of drug-resistant mutations. RESULTS Of the 90 patients enrolled, 53 (58%) were hepatitis B e antigen (HBeAg)-positive at baseline. At Week 48, 74 patients (82% overall; 70% HBeAg-positive and 100% HBeAg-negative) had HBV DNA <400 copies/mL. Six (12%) HBeAg-positive patients achieved HBeAg loss/seroconversion. The percentage of patients with alanine aminotransferase in the normal range increased from 26% at baseline to 66% at Week 48. The percentage of patients with F0 (no or minimal) fibrosis by FibroTest increased from 48% to 51%, and those with F4 (severe) fibrosis decreased from 4% to 1%. No resistance to TDF developed. Treatment was well tolerated. Most adverse events were mild in severity and considered unrelated to study drug. CONCLUSIONS TDF is effective and well tolerated in Asian-American CHB patients in community clinic-based settings, consistent with larger registration trials. Improvement in liver fibrosis was seen in a proportion of patients. No resistance to TDF developed through 48 weeks of treatment. TRIAL REGISTRATION Clinicaltrial.gov identifier NCT00736190.

The assessment of hepatitis B seroprevalence in persons with intravenous drug use history in the Isfahan province: Community-based study. JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2014; 19:65-8. [PMID: 24672567 PMCID: PMC3963325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/22/2013] [Revised: 10/11/2013] [Accepted: 10/31/2013] [Indexed: 11/22/2022]
Abstract
BACKGROUND Hepatitis B with its complications has become one of the universal problems. Injection drug use is one of the most important risk factors in the transmission of hepatitis B. Therefore, we assessed hepatitis B virus prevalence among cases with a history of intravenous drug use (IVDU) as the first announcement-based study in this regard. MATERIALS AND METHODS The announcement-based detection of hepatitis B seroprevalence in volunteers with a history of intravenous drug use was conducted in the Isfahan province. A comprehensive community announcement was made in all the public places and to all physicians, in all the regions. One thousand five hundred and eighty-eight volunteers were invited to the Isfahan reference laboratories and serum samples were tested for HBs-Ag, HBc Ab, and HBs-Ab, using the enzyme-linked immunosorbent assay (ELISA) method. RESULTS In this study, 1588 individuals volunteered, who were estimated to be 50% of all the expected intravenous drug users in the community. HBs Ag was detected in 4.2% of them. HBc Ab and HBs Ab were detected in order in 11.4 and 17.3%, respectively. CONCLUSION We estimated that the seroprevalence of hepatitis B positivity in intravenous drug users was moderate to high. Therefore, it was suggested that this group be encouraged to prevent acquiring infection by vaccination, education, counseling for risk reduction, and treatment of substance abuse, and finally hepatitis B virus (HBV) screening.

[PMID: 23805371 PMCID: PMC3692966 DOI: 10.4329/wjr.v5.i5.208] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2013] [Revised: 03/24/2013] [Accepted: 05/10/2013] [Indexed: 02/06/2023] Open
Abstract
AIM: To assess the value of enlarged perihepatic lymph nodes in determining hepatic histopathology for chronic hepatitis B (CHB) by magnetic resonance imaging (MRI).
METHODS: Sixty-seven patients who were clinically and histologically diagnosed with CHB and 18 healthy subjects without history of liver disease underwent abdominal MRI. Histological diagnosis and hepatic inflammation (grade 0-4) and fibrosis (stage 0-4) were assessed by a simplified system for scoring in chronic viral hepatitis. The major imaging protocol included an axial breath-hold fat suppressed fast spoiled gradient echo T2-weighted imaging (T2WI), axial breath-trigger fat suppressed fast recovery fast spin echo T2WI, and axial and coronal fast imaging employing steady-state acquisition. Perihepatic lymph nodes larger than 5 mm in shortest diameter were noted.
RESULTS: The numbers and size indexes of lymph nodes greater than 5 mm in shortest diameter in hepatic hilum suggested inflammatory activity for subjects with grade 2 or higher, with a high accuracy of diagnosis (the area under the curves > 0.9, P < 0.001). The numbers of lymph nodes were 2 or more with a sensitivity of 87.27%, a specificity of 90.00%, an accuracy of 88.24%, a positive predictive value of 94.12%, and a negative predictive value of 79.41% in patients with grade 2 or higher, and the size indexes were no less than 180 mm2 with a sensitivity of 83.64%, a specificity of 100%, an accuracy of 89.41%, a positive predictive value of 100%, and a negative predictive value of 76.92%. The numbers and size indexes of lymph nodes were not correlated with hepatic fibrosis. The signal intensity indexes of lymph nodes were no significant correlation with histological grading or staging of liver.
CONCLUSION: The numbers and size indexes of enlarged perihepatic lymph nodes for patients with CHB suggest inflammatory activity for subjects with grade 2 or higher.

Abstract
PURPOSE The aim of this study was to characterise gallbladder wall oedema and correlate it with chronic hepatitis B (CHB) on magnetic resonance (MR) imaging. MATERIALS AND METHODS Sixty-seven patients who were clinically and histologically diagnosed with CHB and 18 healthy individuals without any history of liver disease underwent abdominal MR imaging. Hepatic inflammation (grade 0-4) and fibrosis (stage 0-4) for patients were assessed histologically. Gallbladder wall oedema was noted. RESULTS Twelve patients showed gallbladder wall oedema on MR imaging, including six with grade 3 and six with grade 4 disease. There was a statistically significant difference for the presence of gallbladder wall oedema among groups with grade 0-4 (p=0.000), but not between groups with grades 3 and 4 (p=0.729). Gallbladder wall oedema was related to moderate-severe inflammatory activity (p<0.05), alanine transaminase (ALT) (p=0.012) and aspartate aminotransferase (AST) (p=0.027) levels but not to fibrosis or other laboratory data, including serum quantitative DNA for hepatitis B virus (HBV), with the p=0.105-0.846. Sensitivity and specificity for the diagnosis of hepatic moderate-severe inflammation using gallbladder wall oedema were 33.33% and 100%, respectively. CONCLUSIONS Gallbladder wall oedema for patients with CHB can be specifically demonstrated on MR imaging and is correlated with hepatic moderate-severe inflammatory activity, elevated ALT and AST levels but not with fibrosis or other laboratory data, including viremia.

Abstract
Background Hepatitis B (HBV) is the leading cause of cirrhosis and hepatocellular carcinoma worldwide. This study assessed the knowledge, attitudes and practices of people with chronic HBV and the associated factors. Methods This cross-sectional study was conducted at an outpatient adult hepatology clinic at a tertiary hospital in Kuala Lumpur. A self-administered questionnaire was administered on a one-to-one basis to assess knowledge, attitudes, and lifestyle practices of people with chronic HBV. Results The response rate was 89% (n = 483/543). Participants had a mean age of 46.3 (±14.7) years and the mean duration of HBV from time of diagnosis was 12.2 (±8.8) years. The mean knowledge score was 12.57/20 (standard deviation: ±4.4, range: 0–19). Participants aged 30–39 years, with higher educational attainment, employed in professional jobs, longer duration of diagnosis and those without cirrhosis had significantly higher knowledge scores. Age, education level and duration of diagnosis were significant predictors of the knowledge score on standard multiple regression analysis. More than half of the participants were worried of spreading HBV infection to family and friends and worried since the diagnosis. A third of the participants (33.5%) were embarrassed to reveal their diagnosis to the public but most of them (93.6%) would inform their family. Those who reported feeling worried since their diagnosis were more likely to be middle-aged, of Malay ethnicity, have shorter duration of diagnosis of less than 10 years and have received therapy. About half of the participants (50.6%) did not share dining utensils and the majority (93.2%) believed that HBV can be transmitted by sharing of eating and drinking utensils. Older patients were significantly less likely to share utensils. Those who felt worried since diagnosis had significant higher knowledge of HBV. Conclusion The findings highlight the stigma and misconceptions that still exist among the HBV patients. More patient and public education about HBV and its prevention are essential to increase awareness and to demystify the disease.

Abstract
Patients with hepatitis B face uncertainty at diagnosis. Information and support they receive at the early stage of the disease determine their adherence to follow up and treatment. This study aimed to explore the experiences and needs of patients with hepatitis B at diagnosis. A qualitative methodology was used. Nine focus groups (n = 44) were conducted to explore patients' feelings and reaction to the diagnosis, encounters with health care professionals, and their needs. The transcribed data were analyzed using a thematic approach. Most patients were not prepared for the diagnosis and many felt anxious and distressed. This was attributed to poor patients' knowledge, doctor's emphasis on disease complications, and associated stigma. Information about the disease was lacking and patients wanted to know more about the mode of transmission, natural progression of the disease, complications, and treatment options. There was a feeling of "passivity" among patients because there was often no active treatment available at diagnosis. This resulted in patients defaulting surveillance visits and missing the opportunity to start antiviral treatment. Therefore, there is an urgent need to provide sufficient information and education about hepatitis B to newly diagnosed patients, break "bad news" to patients with sensitivity, address their emotional needs, and emphasize on the rationale and importance of surveillance and treatment. This may entail public awareness campaign, implementation of pretest and posttest counseling, and educating doctors on how to communicate the diagnosis and management to patients accurately and sensitively.
