Post-Treatment Occurrence of Serum Cryoglobulinemia in Chronic Hepatitis C Patients. Diagnostics (Basel) 2024; 14:1188. [PMID: 38893714 PMCID: PMC11171999 DOI: 10.3390/diagnostics14111188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 05/21/2024] [Accepted: 05/24/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Persistent cryoglobulinemia after the completion of antiviral treatment is an important consideration of clinical management in chronic hepatitis C patients. We aimed to investigate the occurrence of serum cryoglobulinemia in chronic hepatitis C patients without cryoglobulinemia at the initiation of antiviral treatment. METHODS In total, 776 patients without cryoglobulinemia were assessed for serum cryoglobulinemia after the completion of anti-HCV treatment. Serum cryoglobulinemia precipitation was assessed upon both the initiation and the completion of the treatment and analyzed for the clinical laboratory factors associated with chronic hepatitis C. RESULTS One hundred eighteen (118) patients were checked for serum cryo-precipitation after the completion of the treatment, and eight patients (4.6%) were positive for serum cryoglobulinemia. The patients who tested positive for cryoglobulinemia included a higher proportion of liver cirrhosis patients (4/50%, p = 0.033) and other organ cancer patients (5/62.5%, p = 0.006) than patients who showed no signs of cryoglobulinemia after treatment. In a multivariate analysis, liver cirrhosis (odds ratio [OR]-17.86, 95% confidence interval [95% CI]-1.79-177.35, p = 0.014) and other organ cancer (OR-25.17 95% CI-2.59-244.23, p = 0.005) were independently and significantly associated with positive cryoglobulinemia 3 months after antiviral treatment. CONCLUSIONS Three months after the antiviral DAA therapy had concluded, eight patients tested positive for cryoglobulinemia, representing a 6.7% prevalence. Liver cirrhosis and other organ cancer were independently and significantly associated with positive cryoglobulinemia after antiviral treatment. Further investigation into the causes of positive cryoglobulinemia after DAA antiviral therapy is warranted.

Abstract
Background Hepatocellular carcinoma (HCC) is the most common cancer in Mongolia. The relative importance of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in HCC etiology is known to vary greatly from one part of the world to another. Principally, 95% of HCC patients have chronic viral hepatitis, including 53% hepatitis B virus, 38.9% HCV, and 5.6% have HBV/HCV coinfection. Hepatitis D virus (HDV) infection is widely spread in our country, anti-HDV has been found in more than 25% of carriers who have HBsAg. Materials and methods We analyzed data of patients who had been diagnosed with acute viral hepatitis in the Department of adult hepatitis, National Center for Communicable Diseases in Mongolia from 1952 to 2018. Results A total of 318,831 cases of acute viral hepatitis were registered in Mongolia between 1981 and 2019, which is 34.9 cases per 10,000 population. Of these, 265,931 cases of acute viral hepatitis A, or 28.6 per 10,000 populations, 48,855 cases of acute viral hepatitis B, or 5.5 cases per 10,000 populations, and 2,607 cases of acute viral hepatitis C, or 0.4 cases per 10,000 populations were recorded. Conclusion The prevalence of viral hepatitis in our country was the highest in 1981-1991, but since 2012, the prevalence of infection has steadily decreased. In Mongolia, since 1960, multifaceted programs and activities to combat viral hepatitis have been successfully implemented at the national level.

Abstract
Alcohol use is a major risk factor for the burden of mortality and morbidity. Alcoholic cirrhosis (AC) and alcoholic liver cancer (ALC) are most important and severe liver disease outcomes caused by alcohol use. The objectives of the current study were to investigate the global prevalence and burden of disease in disability-adjusted life years (DALYs) for AC and ALC, based on data from the Global Burden of Disease (GBD). Incidence, prevalence, death, and DALYs for GBDs in different locations, years, sex, and age groups were estimated using DisMod-MR 2.1 and a generic Cause of Death Ensemble Modeling approach. The correlations between the age-standardized incidence rate or age-standardized death rate and gender, sociodemographic index (SDI), and alcohol usage were conducted by Generalized Linear Models. Globally, the changes of age-standardized rates of indicators were not much significant over the 30-year period. However, the changes varied widely across regions. Central Asia and East Europe contributed the highest age-standardized incidence, prevalence, death, and DALYs and increased sharply by past 30 years. Generalized Linear Models (GLMs) showed male gender as a risk factor of AC, with the relative risk of incidence of 1.521 and relative risk of death of 1.503. Globally, there were improvements in overall health with regard to GBDs over the 30 years. However, the prevention of AC and ALC should be promoted in middle and middle-high SDI regions, especially Central Asia and East Europe, whereas more medical resources should be provided to improve treatment levels in low SDI region.

Abstract
Background and aims Bangladesh's unique epidemiological landscape presents an intriguing puzzle. This South Asian nation, with its complex sociodemographic and environmental factors, is home to a diverse array of hepatitis-B virus (HBV) genotypes, identified as Genotype C, with Genotypes D and A also making a significant contribution to the viral landscape. Reviewing such insights is necessary not only to underscore the country's regional diversity in HBV strains but also to bring into focus the clinical implications these genetic variations may have on disease progression and management. Methods A thorough database search covered various sources using relevant keywords like "Hepatitis B virus genotypes", "HBV genotypes in Bangladesh", and "HBV clinical implications". The review synthesized findings and analyzed HBV genotype prevalence and clinical implications in Bangladesh. Results Genotypes C and D collectively represent 82% of chronic hepatitis-B infection (CHB) cases in Bangladesh, underscoring their regional prevalence. The geographic context is pivotal in understanding HBV infection dynamics and disease progression in this area. Notably, genotype C and the presence of A1762T/G1764A mutations appear to have a distinct impact on disease development, potentially affecting the immune response in CHB patients. This highlights the need for tailored management approaches in this specific region. Further research is vital to confirm and elaborate on these findings, particularly in relation to how these mutations influence the host's immune response. Conclusion and clinical significance In summary, studies on HBV genotypes in Bangladesh stress the need for genotype-specific clinical considerations and more research to improve diagnostics and therapies.

Abstract
BACKGROUND Alanine aminotransferase (ALT) measurement is essential for evaluation of liver disease. We validated a novel rapid point-of-care (POC) test for ALT1 against laboratory ALT. METHODS Stored plasma samples from adults with chronic liver disease (Test cohort n = 240; Validation cohort n = 491) were analysed using the BioPoint® antigen immunoassay POC ALT1 lateral flow test, which provides quantitative ALT results (Axxin handheld reader) or semi-quantitative results (visual read, cut off 40 IU/ml). The accuracy of POC ALT1 to detect ALT > 40 IU/L was determined by ROC analysis. In patients with chronic hepatitis B, treatment eligibility (EASL criteria) was determined using POC ALT1 and compared to laboratory ALT. RESULTS POC ALT1 test had good accuracy for laboratory ALT > 40 IU/L: AUROC 0.93 (95% CI: 0.89-0.96) in the Test cohort and AUROC 0.92 (95% CI: 0.88-0.95) in the Validation cohort. POC ALT1 cut off of 0.8 for ALT > 40 IU/L maximised sensitivity (97%) and specificity (71%) in the Test cohort (42% laboratory ALT > 40 IU/L) and yielded PPV 84% and NPV 91% in the Validation cohort (19% laboratory ALT > 40 IU/L). Semi-quantitative POC ALT1 had good accuracy for laboratory ALT in the Validation cohort (AUROC 0.85, 95% CI: 0.81-0.99; sensitivity 77% and specificity 93%). Combined with HBV DNA and transient elastography, both quantitative and semi-quantitative POC ALT1 tests had good accuracy for excluding hepatitis B treatment needs (sensitivity 96%, specificity 78% and NPV 99%). CONCLUSION The POC ALT1 test had good accuracy for elevated ALT levels and for determining treatment eligibility among people with chronic hepatitis B.

Abstract
Introduction The Hepatitis Delta Virus (HDV) is a defective, single-stranded RNA virusoid encoding for a single protein, the Hepatitis Delta Antigen (HDAg), which requires the hepatitis B virus (HBV) envelope protein (HBsAg) for its transmission. Currently, hepatitis D is the most aggressive form of viral hepatitis and treatment options are limited. Worldwide 12 million people are chronically infected with HDV being at high risk for progression to cirrhosis and development of liver cancer. Objectives Although it is well established that Mongolia is the country with the highest prevalence of HDV infections, the information on the molecular epidemiology and factors contributing to HDV sequence diversity are largely unclear. The aim of the study was to characterize the sequence diversity of HDV in rural areas from Mongolia and to determine the extent of HLA class I-associated selection pressure. Patients and methods From the HepMongolia cohort from rural areas in Mongolia, 451 HBsAg-positive individuals were selected and anti-HDV, HDV-RNA and the sequence of the large HDAg was determined. For all individuals the HLA class I locus was genotyped. Residues under selection pressure in the presence of individual HLA class I types were identified with the recently published analysis tool HAMdetector. Results Of 431 HBsAg positive patients, 281 were anti-HDV positive (65%), and HDV-RNA could be detected in 207 of 281 (74%) of patients. The complete large HDAg was successfully sequenced from 131 samples. Phylogenetic analysis revealed that all Mongolian HDV isolates belong to genotype 1, however, they separate into several different clusters without clear regional association. In turn, from phylogeny there is strong evidence for recent local transmission events. Importantly, we found multiple residues with strong support for HLA class I-associated selection pressure consistent with a functional CD8+ T cell response directed against HDV. Conclusion HDV isolates from Mongolia are highly diverse. The molecular epidemiology suggests circulation of multiple subtypes and provides evidence for ongoing recent transmissions.

Abstract
Chronic HCV infection remains a global health concern due to its involvement in hepatic and extrahepatic diseases, including B cell non-Hodgkin lymphoma (BNHL). Clinical and epidemiological evidence support a causal role for HCV in BNHL development, although mechanistic insight is lacking. We performed RNA-sequencing on peripheral B cells from patients with HCV alone, BNHL alone, and HCV-associated BNHL to identify unique and shared transcriptional profiles associated with transformation. In patients with HCV-associated BNHL, we observed the enrichment of an anergic-like gene signature and evidence of clonal expansion that was correlated with the expression of epigenetic regulatory genes. Our data support a role for viral-mediated clonal expansion of anergic-like B cells in HCV-associated BNHL development and suggest epigenetic dysregulation as a potential mechanism driving expansion. We propose epigenetic mechanisms may be involved in both HCV-associated lymphoma and regulation of B cell anergy, representing an attractive target for clinical interventions.

Abstract
Background: The epidemiology of Hepatitis B (HBV) and C (HCV) remains poorly documented in Malaysia. Available statistics are based on data from mostly small studies in special populations. Objectives: In this study, we provide estimates of the proportion of people who are positive for HBs Antigen (HBsAg) and anti-HCV antibody (Ab) among participants in a community screening campaign. Methods: A total of 10,914 subjects participated in the hepatitis screening campaign organized by Hepatitis Free Pahang in 2018 and 2019. A low-cost point-of-care test, which has previously been validated, was used to screen for HBsAg and anti-HCV Ab. All screened positive subjects were recalled to undergo confirmatory serologic tests (enzyme-linked immunosorbent assay) and nucleic acid tests (Real-time Polymerase Chain Reaction. Results: We estimated that 1.17% of adults aged 20 or older who participated in the screening campaign were positive for HBsAg+, and only 0.71 percent were positive for anti-HCV Ab+. Young adults below 30 years of age had a very low proportion of HBsAg+ (0.09%). Women had a lower proportion of HBsAg+ and HCV- Ab+, Chinese had the highest proportion of HBsAg+, while Malay had the highest proportion of anti-HCV Ab+. Conclusions: Among adult participants of screening in Malaysia, chronic HBV is still common, especially among older and Chinese people. Adults with positive anti-HCV Abs are much less common.

Liu CJ, Chen PJ. Changing epidemiology of liver disease in Asia: Dual infection of HBV and HCV. Liver Int 2022; 42:1945-1954. [PMID: 34402183 DOI: 10.1111/liv.15040] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 07/23/2021] [Accepted: 08/11/2021] [Indexed: 12/26/2022]
Abstract
Transmission of hepatitis B virus (HBV) and hepatitis C virus (HCV) is similar regarding the mode of transmission and related risk factors. Therefore, it is not rare to encounter dual HBV/HCV infection in populations at risk of parenteral exposure to hepatitis viruses. Besides, in HBV endemic countries before the era of global HBV vaccination, dual HBV/HCV infection was clinically significant likely because of HCV superinfection over pre-existing HBsAg carriage. Universal childhood HBV vaccination was implemented worldwide since 1992. Public education programs for prevention of new hepatitis viral infections have been actively promoted recently by World Health Organization. Apart from preventive measures, potent anti-HBV agents effective in the control of viral replication have been introduced gradually in the past three decades. Direct acting antiviral agents capable of curing HCV infection in more than 97% of patients with chronic hepatitis C have also been widely implemented in the past decade. These interventions will change the epidemiology of new HBV or HCV mono-infection and dual HBV/HCV infection. Understanding the evolution in the epidemiology of dual HBV/HCV infection is important for evaluation of current public health policy towards infectious disease control in different countries. The changing prevalence of dual HBV/HCV infection in certain Asia-Pacific countries will be re-visited based on endemicity of HBV or HCV, as well as in populations at risk of parenteral viral infection.

Abstract
BACKGROUND This review aimed to identify hepatitis C virus (HCV) prevalence estimates among the general population and six key populations (people who inject drugs, men who have sex with men, sex workers, prisoners/detainees, Indigenous people, and migrants) in the World Health Organization Western Pacific Region (WHO WPR). METHODS Original research articles published between 2016 and 2020 were identified from bibliographic databases. Publications were retrieved, replicas removed, and abstracts screened. Retained full texts were assessed and excluded if inclusion criteria were not met. Methodological quality was assessed using the Johanna Briggs Institute critical appraisal checklist for prevalence data. Data on HCV exposure and active infection were extracted and aggregated and forest plots generated for each population by country. RESULTS There were no HCV prevalence estimates in any population for more than half of WPR countries and territories. Among the 76 estimates, 97% presented prevalence of exposure and 33% prevalence of active infection. General population viraemic prevalence was 1% or less, except in Mongolia. Results confirm the endemic nature of HCV among people who inject drugs, with estimates of exposure ranging from 30% in Cambodia to 76% in Hong Kong. CONCLUSIONS Countries require detailed knowledge of HCV prevalence in diverse populations to evaluate the impact of efforts to support WHO HCV elimination goals. Results provide baseline estimates from which to monitor and evaluate progress and by which to benchmark future elimination efforts.

Post-vaccination Immunity Against Hepatitis B Among Mongolian Adolescents and Youths. HEPATITIS MONTHLY 2022. [DOI: 10.5812/hepatmon-121383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/13/2023]
Abstract
Background: Mongolia introduced vaccination against hepatitis B (HepB) in 1991, leading to a significant decline in the number of infections and mortality associated with the liver disease among this generation. However, the prevalence of hepatitis B virus (HBV) infection and mortality rates among people born before the vaccination program have not declined. Although several studies have been conducted in Mongolia since the introduction of the HepB immunization program, long-term immunity has not been studied at the national level. Objectives: This study aimed to determine the prevalence of HBV infection in adolescents and young adults who received HepB vaccinations at 0, 2, and 8 months after birth and to assess their post-vaccination immunity against hepatitis B. Methods: A population-based cross-sectional study was conducted between December 2016 and December 2018 and included a sample aged 10 to 27 years in Mongolia who had received HepB vaccination according to the national program. A total of 3591 individuals were randomly selected, and data were collected using a structured questionnaire. Blood samples were collected, and serum titers of hepatitis B surface antigen (HBsAg), antibody to HBsAg (anti-HBs), and antibody to hepatitis B core antigen (anti-HBc) were determined by a two-step sandwich chemiluminescent enzyme immunoassay. The age-specific geometric mean of anti-HBs was also estimated. Results: Overall, 98.3% of participants were vaccinated against HepB as infants, according to the interview. The majority had an inadequate anti-HBs titer, while 17.9% had an anti-HBs level of > 10 mIU/mL, of whom 5.7% had immunity induced by HBV infection. Up to 4% of children aged 10 - 19 years and an average of 8% of young adults were serologically positive for HBsAg. The geometric mean anti-HBs titer declined with age, from an average of 40.4 mIU/mL in 10-year-old children to 14.1 IU/mL in 27-year-old adults (P < 0.001). Conclusions: In Mongolia, a small proportion of the population aged 10 - 27 years is immune to HBV, and the geometric mean titer of anti-HBS tended to decrease with age. In order to attain long-term protection against HBV, booster vaccination in adulthood may be necessary.

Abstract
Hepatitis B virus (HBV) infection still remains a major public health issue in the Asia-Pacific region. Most of the burden of HBV-related disease results from infections acquired in infancy through perinatal or early childhood exposure to HBV in Asia-Pacific. Hepatitis B during pregnancy presents unique management issues for both the mother and fetus. These APASL guidelines provide a comprehensive review and recommendations based on available evidence in the literature, for the management of females with HBV infection through every stage of pregnancy and postpartum. These also address the concerns, management challenges, and required follow-up of children born to hepatitis B-positive mothers.

Abstract
BACKGROUND Mongolia is a highly endemic region for chronic hepatitis B (HBV), hepatitis delta (HDV), and hepatitis C (HCV) infections. Aim of this study was to comprehensively characterize chronic viral hepatitis among Mongols living in Southern California. METHODS Three screening events were conducted between August and November 2018, with 528 adult Mongols tested for HBV and HCV. HBsAg (+) individuals (CHB) underwent additional testing for HDV RNA and anti-HDV. Liver tests, platelet count, and FibroScan™ were performed on CHB and chronic HCV (CHC) individuals. RESULTS Fifty-one out of 534 were HBsAg reactive (9.7%), and all were foreign-born. Mean age of CHB individuals was 37.8 (range 18-69) years. Forty-six out of 51 were HBeAg (-). HBV genotypes were exclusively D2 or A1. Twenty-one out of 51 (41.2%) were anti-HDV (+) and 17/51 (33.3%) were HDV RNA (+). HDV RNA (+) individuals had significantly higher ALT, fibrosis-4 score, and liver stiffness compared to HDV RNA (-) individuals. Incidence of advanced fibrosis was higher in HDV RNA (+) individuals (57% vs. 13%, p = 0.013). Forty-eight (9.1%) individuals were anti-HCV (+) and 19 (3.6%) were HCV RNA (+). Mean age of CHC individuals was 40.2 (range 28-71) years. Prevalence of anti-HCV (+) was higher among those born between 1945 and 1965 versus those born after 1965 (18.8% vs. 7.9%, p = 0.025). Genotype 1b was predominant. Incidence of cirrhosis was 7% among all participants. CONCLUSIONS Mongols living in the USA are at high risk for CHB and CHC infections. One-third of CHB individuals had CHD superinfection with advanced fibrosis. Universal screening for viral hepatitis in Mongols in the USA is mandatory.

Abstract
OBJECTIVE To characterize hepatitis C virus (HCV) infection epidemiology in Mongolia. METHOD Publications on HCV antibody (Ab) and RNA prevalence, and/or genotypes/subtypes were systematically reviewed and reported following PRISMA guidelines. Random-effects meta-analyses and age adjustments were conducted to estimate the prevalence of Mongolians exposed to HCV (pooled HCV-Ab prevalence) by time period, sex, and at-risk populations; and to estimate the prevalence of chronically-infected HCV individuals. RESULTS The national pooled HCV-Ab prevalence was 12.3% in 2000-2009 and 11.2% in 2013. Sex-specific pooled prevalence appeared higher among females than males (14.0% versus 6.8%). Age-specific pooled prevalence significantly increased from 3.7% among children (aged 0-10 years) to 34.1% among people aged ≥50 years (p < 0.001). Among the adult general population (low-risk population), the national age-adjusted prevalence was 8.1%. Age-adjusted chronic infection prevalence in adults was 6.0%. Among healthcare workers, pooled prevalence was 18.0%. Among patients with liver diseases, pooled prevalence was 53.7%. Among individuals engaging in risky sexual behaviors, pooled prevalence was 11.1%. The identified circulating genotypes/subtypes were 1b (58.0%), 2a (21.7%), and 1a (20.2%). CONCLUSION The national HCV prevalence in Mongolia appeared to be among the highest worldwide. Higher prevalence in the clinical setting indicated potential ongoing HCV iatrogenic and occupational transmission. Additionally, HCV transmission in community settings should be investigated.

Abstract
Early diagnosis of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections is pivotal for optimal disease management. Sensitivity and specificity of 19 rapid diagnostic test (RDT) kits by different manufacturers (ABON, CTK Biotech, Cypress Diagnostics, Green Gross, Human Diagnostic, Humasis, InTec, OraSure, SD Bioline, Wondfo) were assessed on serum samples of 270 Mongolians (90 seropositive for hepatitis B surface antigen (HBsAg), 90 seropositive for hepatitis C antibody (HCV-Ab), 90 healthy subjects). All tested RDTs for detection of HBsAg performed with average sensitivities and specificities of 100% and 99%, respectively. Albeit, overall sensitivity and specificity of RDTs for detection of HCV-Ab was somewhat lower compared to that of HBsAg RDTs (average sensitivity 98.9%, average specificity 96.7%). Specificity of RDTs for detection of HCV-Ab was dramatically lower among HBsAg positive individuals, who were 10.2 times more likely to show false positive test results. The results of our prospective study demonstrate that inexpensive, easy to handle RDTs are a promising tool in effective HBV- and HCV-screening especially in resource-limited settings.

Barriers to treatment of chronic hepatitis C with direct acting antivirals in an urban clinic. Ann Hepatol 2020; 18:304-309. [PMID: 31053544 DOI: 10.1016/j.aohep.2018.06.001] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 05/28/2018] [Accepted: 06/19/2018] [Indexed: 02/04/2023]
Abstract
INTRODUCTION AND AIM Direct-acting antiviral (DAA) agents are highly effective for treatment of chronic hepatitis C virus (HCV) yet access to treatment remains a serious challenge. The aim of this study was to identify barriers to treatment initiation with DAA-containing regimens in an urban clinic setting. MATERIALS AND METHODS A retrospective cohort of all chronic HCV patients seen in an urban academic practice in Jacksonville, FL, USA from 1/2014 to 1/2017 was analyzed. Baseline characteristics were recorded and a review of medical records was performed to identify barriers to treatment initiation and overall success rates. RESULTS Two-hundred and forty patients with chronic HCV were analyzed. Fifty-six percent of patients were African-American and 63% were insured through Medicaid/county programs or uninsured. Sixty-nine percent had barriers to initiating antiviral therapy categorized as psychosocial (n=112), provider (n=26), medical (n=20), and insurance-related factors (n=7). The most commonly encountered psychosocial barriers included failure to keep appointments (79/240, 33%), active substance abuse (18/240, 8%), and failure to obtain laboratory testing (11/240, 5%). Overall, only 27% of patients evaluated were initiated on DAA-containing regimens with 18% reaching SVR12 within the 36-month study period. CONCLUSION In conclusion, only 27% of patients who presented to an urban academic practice with chronic HCV received DAA-containing regimens over a 36-month period. Psychosocial issues were the major barriers to antiviral therapy. These findings illustrate the need for an integrated approach that addresses psychosocial factors as well as comorbidities and adherence to care in order to increase rates of HCV treatment in at risk patients.

Abstract
INTRODUCTION The prevalence of hepatitis C virus (HCV) infection is affected by demographic, virological, clinical, and lifestyle-related factors and varies in different regions in Brazil or worldwide. The present study aimed to clarify the epidemiological patterns of HCV infection in the interior region of Brazil. METHODS This study was conducted in the Southern Triangle Macro-region of the state of Minas Gerais, Brazil, according to the guidelines of the National Program for the Prevention and Control of Viral Hepatitis. The participants answered a structured questionnaire on social and epidemiological factors. Immunochromatographic rapid tests were used for the qualitative detection of antibodies against HCV in whole blood (Alere HCV® Code 02FK10) in adult subjects by a free-standing method. RESULTS Of 24,085 tested individuals, 184 (0.76%) were anti-HCV positive. The majority of anti-HCV-positive individuals were born between 1951 and 1980 (n=146 [79.3%]), with 68 women and 116 men. Identified risk factors included syringe and/or needle sharing (p = 0.003), being in prison (p = 0.004), and having tattoos or piercings (p = 0.005) and were significantly associated with the decade of birth. CONCLUSIONS The study shows the importance of testing populations at risk for HCV infection, including incarcerated individuals, those with tattoos or piercings, those who share or have shared syringes or needles, and those in high-risk birth cohorts (1950s, 1960s, and 1970s) in the Southern Triangle Macro-region.

World J Gastroenterol 2019; 25:4749-4763. [PMID: 31528099 PMCID: PMC6718041 DOI: 10.3748/wjg.v25.i32.4749] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 07/10/2019] [Accepted: 07/19/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Liver cancer is the sixth most commonly diagnosed cancer and the fourth leading cause of cancer death worldwide. Socioeconomic development, indicated by the Human Development Index (HDI), is closely interconnected with public health. But the manner in which social development and medical advances influenced liver cancer patients in the past decade is still unknown.
AIM To investigate the influence of HDI on clinical outcomes for patients with existing liver cancer from 2008 to 2018.
METHODS The HDI values were obtained from the United Nations Development Programme, the age-standardized incidence and mortality rates of liver cancer were obtained from the GLOBOCAN database to calculate the mortality-to-incidence ratio, and the estimated 5-year net survival of patients with liver cancer was provided by the CONCORD-3 program. We then explored the association of mortality-to-incidence ratio and survival with HDI, with a focus on geographic variability across countries as well as temporal heterogeneity over the past decade.
RESULTS From 2008 to 2018, the epidemiology of liver cancer had changed across countries. Liver cancer mortality-to-incidence ratios were negatively correlated and showed good fit with a modified “dose-to-inhibition response” pattern with HDI (r = -0.548, P < 0.0001 for 2018; r = -0.617, P < 0.0001 for 2008). Cancer survival was positively associated with HDI (r = 0.408, P < 0.01) and negatively associated with mortality-to-incidence ratio (r = -0.346, P < 0.05), solidly confirming the interrelation among liver cancer outcome indicators and socioeconomic factors. Notably, in the past decade, the HDI values in most countries have increased alongside a decreasing tendency of liver cancer mortality-to-incidence ratios (P < 0.0001), and survival outcomes have simultaneously improved (P < 0.001), with significant disparities across countries.
CONCLUSION Socioeconomic factors have a significant influence on cancer outcomes. HDI values have increased along with improved cancer outcomes, with significant disparities among countries.

Abstract
Introduction Mongolia has the highest liver cancer incidence in the world. Hepatocellular carcinoma is the most prevalent primary liver cancer, and the most common risk factors are hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. Although viral hepatitis occurs mostly in the developing world, migration of people from high prevalence countries contributes to the health outcomes of the United States. Data on Mongolian Americans is limited. The objective of this study was to estimate HBV and HCV infection prevalence among Mongolia-born immigrants living in the Washington, District of Columbia, metropolitan area. Methods We tested Mongolia-born immigrants for chronic hepatitis at community-based screening events from 2016 to 2017. Descriptive statistics were generated to describe the screening results. Bivariate analysis was conducted to examine the relationship between hepatitis prevalence and sociodemographic characteristics. Results Of 634 participants, most did not speak English primarily, were uninsured, and did not have a regular primary care provider. Eighty-two participants (12.9%) had chronic HBV or HCV infection after accounting for HBV and HCV co-infection. Thirty-nine (6.2%) were chronically infected with HBV, and 233 (36.8%) were susceptible to HBV. Sixty-three (9.9%) participants were positive for HCV exposure, and 45 (7.1%) had confirmed chronic HCV infection. While no sociodemographic characteristics were associated with HBV infection, age and primary spoken language (Mongolian) were significantly associated with HCV exposure. Conclusion Foreign-born immigrants such as Mongolian Americans have a high prevalence of chronic viral hepatitis infection. Targeted screening, vaccination, and treatment programs can help decrease immigrant risk for developing hepatocellular carcinoma.

Abstract
This Review presents current epidemiological trends of the most common liver diseases in Asia-Pacific countries. Hepatitis B virus (HBV) remains the primary cause of cirrhosis; despite declining prevalence in most Asian nations, this virus still poses a severe threat in some territories and regions. Mortality resulting from HBV infection is declining as a result of preventive measures and antiviral treatments. The epidemiological transition of hepatitis C virus (HCV) infection has varied in the region in the past few decades, but the medical burden of infection and the prevalence of its related cancers are increasing. The lack of licensed HCV vaccines highlights the need for novel treatment strategies. The prevalence of nonalcoholic fatty liver disease (NAFLD) has risen in the past decade, mostly owing to increasingly urbanized lifestyles and dietary changes. Alternative herbal medicine and dietary supplements are major causes of drug-induced liver injury (DILI) in some countries. Complications arising from these chronic liver diseases, including cirrhosis and liver cancer, are therefore emerging threats in the Asia-Pacific region. Key strategies to control these liver diseases include monitoring of at-risk populations, implementation of national guidelines and increasing public and physician awareness, in concert with improving access to health care.
