Increased risk of cirrhosis and its decompensation in chronic hepatitis B patients with newly diagnosed diabetes: a nationwide cohort study

Risk Factors for Development of Cirrhosis in Chronic Viral Hepatitis B Patients Who Had Persistent Viral Suppression With Antiviral Therapy

Background and aims

Chronic viral hepatitis B (CHB)-infected patients occasionally develop cirrhosis despite having persistent viral suppression with antiviral therapy. We aimed to identify risk factors for developing cirrhosis in hepatitis B virus (HBV)-suppressed patients.

Methods

We conducted a case-control study involving 120 noncirrhotic CHB-infected patients achieving viral suppression with antiviral treatment, with 40 cases developing cirrhosis and 80 age-, sex-, and Fibrosis-4 (FIB-4)-matched controls. Clinical and laboratory data at viral suppression, including body mass index (BMI), comorbidities, pretreatment HBV viral load, HBe antigen status, hepatitis C virus (HCV) and HIV coinfections, liver chemistries, and AST to Platelets Ratio Index (APRI) values, were retrospectively abstracted. Risk factors for cirrhosis post-HBV suppression were identified using Cox proportional hazard analysis.

Results

Case and control groups had similar ages (51.4 ± 9.9 vs. 51.4 ± 10.2 years), proportions of males (80% vs. 80%), and FIB-4 values (1.32 vs. 1.31). The cirrhosis group showed significantly higher BMI (25.1 vs. 22.7, P = 0.01) and more diabetes prevalence (50.0% vs. 26.3%, P = 0.01), while other comorbidities and laboratory parameters were comparable (P > 0.05). By univariate analysis, BMI >23 kg/m2, diabetes, and APRI >0.7 were significantly associated with cirrhosis, with hazard ratios (HRs) (95%CI) of 2.99 (1.46-6.13), 2.31 (1.23-4.36), and 2.71 (1.05-6.99), P = 0.003, 0.010, and 0.039, respectively. In multivariate analyses adjusted for APRI, BMI>23 kg/m2 remained significantly associated with cirrhosis (aHR: 2.76, P = 0.006), while diabetes showed borderline significance (aHR: 1.99, P = 0.072).

Conclusions

In HBV-infected patients achieving viral suppression with therapy, a BMI >23 kg/m2 increases the risk of cirrhosis. Therefore, a comprehensive approach addressing metabolic factors is imperative for preventing disease progression in HBV-infected patients.

Assessing the impact of comorbid type 2 diabetes mellitus on the disease burden of chronic hepatitis B virus infection and its complications in China from 2006 to 2030: a modeling study

BACKGROUND

China bears a high burden of both hepatitis B virus (HBV) infection and type 2 diabetes mellitus (T2DM). T2DM accelerates the progression of liver disease among individuals infected with HBV. This study aims to assess the excess disease burden caused by comorbid T2DM among HBV-infected individuals in China.

METHODS

We estimated the disease burden of HBV and its complications in China from 2006 to 2030 using individual-based Markov models. The baseline population consisted of 93 million HBV-infected individuals derived from the 2006 National Serological Epidemiological Survey. We developed two models: one incorporated the impact of T2DM on the disease progression of HBV infection, while the other did not consider the impact of T2DM. By comparing the outcomes between these two models, we estimated the excess disease burden attributable to comorbid T2DM among HBV-infected individuals.

RESULTS

The incidence of severe HBV complications, including cirrhosis, hepatocellular carcinoma (HCC), and liver-related deaths, exhibited an increasing trend from 2006 to 2030 among the Chinese HBV-infected population. Comorbid T2DM increased the annual incidence and cumulative cases of severe HBV complications. From 2006 to 2022, comorbid T2DM caused 791,000 (11.41%), 244,000 (9.27%), 377,000 (8.78%), and 796,000 (12.19%) excess cases of compensated cirrhosis, decompensated cirrhosis, HCC, and liver-related deaths, respectively. From 2023 to 2030, comorbid T2DM is projected to result in an 8.69% excess in severe HBV complications and an 8.95% increase in liver-related deaths. Among individuals aged 60 and older at baseline, comorbid T2DM led to a 21.68% excess in severe HBV complications and a 28.70% increase in liver-related deaths from 2006 to 2022, with projections indicating a further 20.76% increase in severe HBV complications and an 18.31% rise in liver-related deaths over the next seven years.

CONCLUSIONS

Comorbid T2DM imposes a substantial disease burden on individuals with HBV infection in China. Healthcare providers and health policymakers should develop and implement tailored strategies for the effective management and control of T2DM in individuals with HBV infection.

The interplay between chronic hepatitis B and diabetes mellitus: A narrative and concise review

Type 2 diabetes mellitus (T2DM) is a prevalent metabolic disorder among individuals with chronic hepatitis B (CHB), contributing to additional adverse impacts on both hepatic and extrahepatic systems. Existing evidence suggests a potential positive association between CHB and the development of insulin resistance and T2DM. The presence of T2DM in CHB patients is associated with an increased risk of liver fibrosis, cirrhosis, decompensation, and hepatocellular carcinoma (HCC) occurrence. Moreover, it elevates the risk of non-liver cancers and all-cause mortality in this population. T2DM also serves as the key element in metabolic dysfunction-associated steatotic liver disease, which is prevalent in the CHB population. Although specific guidelines for managing T2DM in CHB patients have not been proposed, some studies indicated that intensive glycemic control may benefit the prognosis of these patients. Additionally, specific antidiabetic agents, such as metformin and thiazolidinediones, promise to reduce HCC risk. However, unresolved questions, including the optimal glycemic control target and the selection of antidiabetic agents for CHB patients, remain and thus warrant further investigations through well-designed prospective trials. Implementing a standardized protocol encompassing regular monitoring, risk stratification, and early intervention using a multidisciplinary framework may improve the outcomes of diabetic CHB patients.

Chronic hepatitis B infection and diabetes mellitus: a double liver trouble?

BACKGROUND

Concomitant Diabetes mellitus (DM) is commonly recognized in patients with chronic hepatitis B (CHB) infection, although its impact on liver-related outcomes remains controversial. We aimed to evaluate the effect of DM on the course, management and outcome of patients with CHB.

METHODS

We performed a large retrospective cohort study utilizing the Leumit-Health-Service (LHS) database. We reviewed electronic reports of 692106 LHS members from different ethnicities and districts in Israel from 2000-2019 and included patients with CHB diagnosis based on ICD-9-CM codes and supportive serology results. These were divided into two cohorts of patients with CHB and DM (CHD-DM) (N.=252) and those with CHB without DM (N.=964). Clinical parameters, treatment figures and patients' outcomes were compared and multiple regression models and Cox regression analysis were performed to investigate the association between DM and cirrhosis/HCC risk in CHB patients.

RESULTS

CHD-DM patients were significantly older (49.2±10.9 vs. 37.9±14, P<0.001), and had higher rates of obesity (BMI>30) and NAFLD (47.2% vs. 23.1%, and 27% vs. 12.6%, P<0.001, respectively). Both groups had a predominance of inactive carrier (HBeAg negative infection) state, but the HBeAg seroconversion rate was significantly lower in the CHB-DM group (25% vs. 45.7%; P<0.01). Multivariable Cox regression analysis showed that DM was independently associated with increased cirrhosis risk (HR 2.63; P=0.002). Older age, advanced fibrosis and DM were associated with HCC, but DM did not reach significance (HR 1.4; P=0.12) possibly due to the small number of HCC cases.

CONCLUSIONS

Concomitant DM in CHB patients was significantly and independently associated with cirrhosis and possibly with increased risk of HCC.

The impact of concomitant metabolic dysfunction-associated fatty liver disease on adverse outcomes in patients with hepatitis B cirrhosis: a propensity score matching study

BACKGROUND AND AIMS

In cirrhotic patients, the clinical relevance of metabolic dysfunction-associated fatty liver disease (MAFLD) is unclear. We aimed to research the relationship between MAFLD and adverse clinical outcomes in patients with hepatitis B cirrhosis.

METHODS

A total of 439 patients with hepatitis B cirrhosis were enrolled. Abdominal MRI and computed tomography were used to calculate liver fat content in order to evaluate steatosis. The Kaplan-Meier method was implemented to generate survival curves. The independent risk factors for prognosis were identified by multiple Cox regression. Propensity score matching (PSM) was used to reduce the influence of confounding factors. This study explored the relevance between MAFLD and mortality, first decompensation and further decompensation.

RESULTS

In our study, most patients were decompensated cirrhosis (n = 332, 75.6%) and the ratio of decompensated cirrhosis patients in non-MAFLD to MAFLD group was 199 : 133. Compared to the non-MAFLD group, patients with MAFLD had worse liver function which mainly reflected that there were more Child-Pugh C patients and higher model for end-stage liver disease score in the MAFLD group. A total of 207 adverse clinical events occurred in the total cohort during a median follow-up of 47 months, including 45 deaths, 28 hepatocellular carcinoma, 23 first decompensation and 111 further decompensation. Cox multivariate analysis showed that MAFLD was an independent risk factor for death [hazard ratio (HR) 1.931; 95% confidence interval (CI) 1.019-3.660; P = 0.044 HR 2.645; 95% CI, 1.145-6.115; P = 0.023] and further decompensation (HR 1.859; 95% CI, 1.261-2.741; P = 0.002 HR 1.953; 95% CI, 1.195-3.192; P = 0.008) before and after PSM. In decompensated group with MAFLD, diabetes had a more significant effect on adverse prognosis than overweight or obesity and other metabolic risk factors.

CONCLUSION

In patients with hepatitis B cirrhosis, concomitant MAFLD can predict a higher risk of further decompensation and death among decompensated individuals. According to patients among MAFLD, diabetes may be a major factor in the occurrence of adverse clinical events.

Ageing and non-liver comorbidities in population with chronic hepatitis B infection in the western pacific region from 1990 to 2019

Objectives: This study examined the age structure and burden of non-liver noncommunicable diseases in population with chronic hepatitis B virus (HBV) infection in the Western Pacific Region (WPR) from 1990 to 2019. Methods: We estimated ageing trends and the prevalence of non-liver NCDs among the HBV-infected population and the general population in 31 countries/areas in the Western Pacific Region from 1990 to 2019 based on the Global Burden of Disease 2019 dataset. Results: The proportion of individuals aged 60 or older among the HBV-infected population has increased at a faster rate compared to the general population, whereas the proportion of individuals younger than 19 years has decreased rapidly over the past three decades. Among the HBV-infected population, the prevalence of most (29/31) NCDs increased from 1990 to 2019, with the top three most significant increases found for non-Hodgkin's lymphoma (789.94% increase), prostate cancer (512.40% increase), and kidney cancer (411.34% increase). The prevalence of NCDs among the HBV-infected population increased faster than in the general population over the past three decades, especially in countries with rapid population ageing. Conclusion: This study highlights the increasing burden of non-liver comorbidities among the HBV-infected population. The integrated management of non-liver NCDs among this population should be implemented.

Global burden of hepatitis B attributable to modifiable risk factors from 1990 to 2019: a growing contribution and its association with socioeconomic status

BACKGROUND

Hepatitis B is a global public health concern, and modifiable risk factors can accelerate progression of this disease. The burden of hepatitis B attributable to modifiable risk factors has not been well evaluated. We aimed to estimate the disease burden of hepatitis B attributable to tobacco, alcohol use, and a high body mass index (BMI) to guide lifestyle interventions in the management of patients with hepatitis B virus (HBV) infection.

RESULTS

In 2019, 33.73% of hepatitis B age-standardized deaths and 34.52% of disability-adjusted life-years (DALYs) were attributable to tobacco, alcohol use, and a high BMI. The proportion showed an increasing trend that 28.23% of deaths and 27.56% of DALYs were attributable to the three modifiable risk factors in 1990. The hepatitis B burden attributable to modifiable risk factors was disparate across regions and countries. Countries with a low socioeconomic status have a high burden of hepatitis B owing to modifiable risk factors. Countries with a high-level sociodemographic index also had an increasing burden of hepatitis B attributable to a high BMI.

CONCLUSIONS

Lifestyle interventions are warranted in hepatitis prevention strategies and plans of action. Countries with low and middle socioeconomic development should be prioritized, and countries with high socioeconomic development should be aware of the novel challenge of a high BMI-related disease burden.

Association of Dipeptidyl Peptidase-4 Inhibitors Use with Reduced Risk of Hepatocellular Carcinoma in Type 2 Diabetes Patients with Chronic HBV Infection

Previous studies have indicated that HBV infection and T2DM are the factors that increase the risk of developing HCC. The experimental evidence has shown that antiglycemic agents may reduce the risk of HCC. However, the effect of dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) on the risk of HCC in T2DM patients with chronic HBV infection remains unclear. In this retrospective cohort study, we extracted patients with T2DM and chronic HBV infection from the National Health Insurance Research Database (NHIRD) in Taiwan. The cases were divided into DPP-4 inhibitors use and non-use groups, according to whether they received DPP-4 inhibitors treatment, and the risk of HCC was compared between the two groups. At the end of the follow-up, approximately 2.33% of DPP-4 inhibitors users had received an HCC diagnosis compared with 3.33% of non-DPP-4 inhibitors users (p < 0.0001). After multivariate adjustment, DPP-4 inhibitors users showed a significant reduction in HCC risk (adjusted hazard ratios (aHRs): 0.53; 95% confidence intervals (CIs): 0.44-0.65). In conclusion, this population-based retrospective cohort study indicated that, in T2DM patients with chronic HBV infection, the use of DPP-4 inhibitors significantly reduced the risk of developing HCC compared with non-DPP-4 inhibitors use.

Glycemic burden and the risk of adverse hepatic outcomes in patients with chronic hepatitis B with type 2 diabetes

BACKGROUND AND AIMS

Type 2 diabetes (T2D) is common among patients with chronic hepatitis B infection (CHB) and has been associated with increased risk of carcinogenesis, including HCC. We investigated factors associated with HCC and fibrosis progression among patients with CHB with T2D (CHB+T2D).

APPROACH AND RESULTS

Chinese patients with CHB were prospectively recruited for the incidence of HCC and fibrosis progression defined by transient elastography. Among patients with CHB+T2D, glycemic control was assessed by mean glycated hemoglobin (HbA1c) and HbA1c variability determined using HbA1c measurements in the 5 years preceding recruitment. A total of 2330 patients with CHB were recruited (mean age 54.6 ±11.8 years old, 55.5% male, 57.9% antiviral-treated), with 671 (28.8%) having CHB+T2D (mean T2D duration 7.2 ± 4.6 years, mean HbA1c 7.2 ± 0.9%). T2D was independently associated with HCC (HR 2.080, 95% CI 1.343-3.222) and fibrosis progression (OR 4.305, 95% CI 3.416-5.424) in the overall cohort. In patients with CHB+T2D, factors reflecting glycemic burden (T2D duration [HR 1.107, 95% CI 1.023-1.198]), mean HbA1c (HR 1.851, 95% CI 1.026-3.339), time reaching target HbA1c (HbA1c-TRT; HR 0.978, 95% CI 0.957-0.999), liver stiffness (HR 1.041-1.043), and smoking (HR 2.726-3.344) were independently associated with HCC (all p < 0.05), but not HbA1c variability or controlled attenuation parameter. The same glycemic burden-related factors (T2D duration, mean HbA1c, and HbA1c-TRT), in addition to baseline fasting glucose, baseline HbA1c, AST and antiviral therapy, were independently associated with fibrosis progression at 3 years.

CONCLUSIONS

High glycemic burden was associated with HCC development and fibrosis progression among patients with CHB+T2D, highlighting the importance of glycemic control in reducing liver-related complications.

Factors associated with high alanine aminotransferase (ALT) and cirrhosis in people living with HIV on combination antiretroviral treatment (cART) in the Asia-Pacific

Liver disease is a growing burden among people living with HIV (PLHIV) in resource-limited settings. As an indicator of liver disease, risk factors of high alanine aminotransferase (ALT) and cirrhosis were assessed among PLHIV in the TREAT Asia HIV Observational Database (TAHOD). Patients on combination antiretroviral therapy (cART) with a pre-cART ALT measurement and at least one follow-up ALT measurement were included. Factors associated with high ALT (ALT levels > 5 times its upper limit of normal) were analyzed using repeated measure logistic regression over a 10-year follow-up period. Liver cirrhosis was defined as having an AST to Platelet Ratio Index score > 1.5, fibrosis-4 score > 3.25, or a clinical diagnosis of cirrhosis. Cox regression analysis stratified by site was used to analyze factors associated with cirrhosis among those in follow-up after 2015. Of 5182 patients, 101 patients (1.9%) had high ALT levels with hepatitis C virus (HCV) antibody positive (odds ratio [OR]: 4.98, 95% confidence interval [CI]: 2.82-8.77, p < 0.001) and ever high alcohol consumption (OR: 2.33, 95% CI: 1.00-5.46, p = 0.050) as likely factors. Among 6318 PLHIV in the liver cirrhosis analysis, 151 (2%) developed cirrhosis (incidence rate = 0.82 per 100 person-years). Those HCV-antibody positive (hazard ratio [HR]: 5.54, 95% CI: 3.75-8.18, p < 0.001) and had high alcohol consumption (HR: 2.06, 95% CI: 1.23-3.45, p = 0.006) were associated with liver cirrhosis. HCV-antibody positive and high alcohol consumption are factors associated with high ALT. With raised ALT levels as a known factor associated with liver cirrhosis, greater efforts are required in managing ALT levels and reducing the risk of developing liver cirrhosis among those positive for HCV-antibody and those who consume alcohol.

Impact of NAFLD on the outcome of patients with chronic hepatitis B in Asia

Hepatitis B virus (HBV) infection and nonalcoholic fatty liver disease (NAFLD) are two major causes of chronic liver disease (CLD) that can cause liver cirrhosis and hepatocellular carcinoma (HCC). It is a trend to superimpose NAFLD on chronic HBV infection in Asia. This review presents the epidemiology of concurrent NAFLD in chronic hepatitis B (CHB) patients and focuses on the impact of concurrent NAFLD on the outcome of CHB patients in Asia. Although CHB patients tend to have a lower prevalence and incidence of NAFLD than the general population, concurrent NAFLD among CHB patients is still common and has an upward trend over time. Concurrent NAFLD can promote hepatitis B surface antigen (HBsAg) seroclearance and might inhibit HBV replication but exacerbate liver fibrosis. The impacts of concurrent NAFLD on HCC risk, all-cause mortality and antiviral treatment response in CHB patients remain controversial.

Propranolol use in patients with cirrhosis and refractory ascites: A nationwide study

BACKGROUND

The impact of propranolol on patients with cirrhosis and refractory ascites is controversial. We conducted a nationwide longitudinal cohort study to compare the survival between patients with cirrhosis and refractory ascites, with and without using propranolol.

METHODS

Data of patients with cirrhosis and refractory ascites using propranolol, and controls matched by age and gender, were extracted from The National Health Insurance Research Database of Taiwan. The baseline demographic characteristics were compared between groups. Cox regression analysis was used to examine the predictors of mortality.

RESULTS

In this study, 1788 patients were enrolled in each group; 1304 patients (72.9%) in the propranolol group and 1445 patients (80.8%) in the control group died (P < 0.001). The mean survival was 34.3 ± 31.2 months in the propranolol group and 20.8 ± 26.6 months in the control group (P < 0.001). Propranolol (hazard ratio [HR]: 0.60, 95% confidence interval [CI]: 0.55-0.64, P < 0.001), statins (HR: 0.43, 95% CI: 0.34-0.56, P < 0.001), age (HR: 1.02, 95% CI: 1.01-1.02, P < 0.001), and diabetes mellitus (HR: 1.14, 95% CI: 1.05-1.24, P = 0.002) were the independent predictors for mortality.

CONCLUSIONS

Use of propanolol was associated with reduced mortality, compared with controls, in this nationwide cohort of patients with cirrhosis and refractory ascites.

Characteristics and Clinical Significance of Intestinal Microbiota in Patients with Chronic Hepatitis B Cirrhosis and Type 2 Diabetes Mellitus

BACKGROUND

Chronic hepatitis B cirrhosis is often accompanied by glucose metabolism disorder, and intestinal microbiota was closely related to both cirrhosis and diabetes. There are few studies on the role of intestinal microbiota in hepatitis B liver cirrhosis and diabetes mellitus (LCDM). The purpose of this study was to investigate the characteristics of intestinal microbiota in patients with LCDM and to evaluate the relationship between the severity of intestinal microbiota imbalance and clinical significance.

METHODS

A case-controlled study was conducted. People who met the inclusion and exclusion criteria of chronic HBV-related liver cirrhosis (LC), LCDM, and healthy controls (HC) were enrolled in, and their fecal and blood samples were collected. The V3-V4 region of 16s rDNA gene of fecal microbiota was sequenced; the bioinformatics analysis including α-diversity, β-diversity, and linear discriminant analysis (LDA) effect size (LEfSe) was performed; and the correlation between bacteria and clinical indexes was analyzed.

RESULTS

A total of 70 participants completed fecal and blood tests, including 20 HC, 20 LCDM, and 30 LC. The α diversity of intestinal microbiota in the LCDM decreased than that in the HC. The abundance of Proteobacteria, Streptococcus, Escherichia-Shigella, and Lactobacillus increased, while the abundance of Bacteroidota, Bacteroides, Prevotella, Faecalibacterium, and Lachnospira decreased in the LCDM compared with the HC. The abundance of Lactobacillus, Roseburia, and Veillonella and the degree of hepatitis B cirrhosis dysbiosis indicator (HBCDI) increased in the LCDM than in the LC. The abundance of Escherichia-Shigella, Veillonella, and Lactobacillus positively correlated with liver injury and fasting blood glucose (FBG) level. The abundance of Escherichia-Shigella, Veillonella, Streptococcus, and Lactobacillus increased more significantly when FBG and glycosylated hemoglobin level increased.

CONCLUSION

Intestinal microbiota of patients with LCDM was significantly disordered, and the degree was more serious than that cirrhosis patients without diabetes.

Hepatic steatosis and development of type 2 diabetes: Impact of chronic hepatitis B and viral specific factors

BACKGROUND

Chronic hepatitis B (CHB) was associated with a lower prevalence of nonalcoholic fatty liver disease (NAFLD). The impact of CHB on the link between NAFLD and type 2 diabetes (T2D) and related virological implications remain unclear.

METHODS

We recruited 2255 middle-to older-aged individuals who were examined serially for hepatic steatosis by ultrasonography and blood biochemistry as part of a population-based hepatocellular-carcinoma cohort study. In CHB patients, hepatitis B surface antigen (HBsAg) seroclearance and variation in viral load trajectory were also evaluated.

RESULTS

During the average follow-up of 6 years, 168 participants developed T2D. CHB, as compared with uninfected subjects, was associated with lower risks for both new development and persistence of hepatic steatosis. Furthermore, the risk of steatosis decreased with higher levels of past viral load trajectories (p for trend = 0.0002). However, concomitant steatosis at baseline in CHB patients was still significantly associated with a 1.98-fold increased risk for T2D after multivariate adjustment including age, impaired fasting glucose, cirrhosis, and time-varying body mass index, although CHB reduced the propensity of hepatic steatosis to develop diabetes, especially for patients with high levels of past viral-load trajectory. In CHB, the functional cure of HBV infection, as indicated by HBsAg seroclearance, was associated with a 1.41-fold (95% CI 1.12-1.79) increased risk of steatosis. In addition, the increased risk for progressive impairment of glucose metabolism due to steatosis was especially prominent after HBsAg seroclearance.

CONCLUSION

The data showed that HBV interferes with fatty liver disease and modulates its related T2D risk, offering additional insight into the interplay between NAFLD and CHB.

Effects of Metformin Exposure on Survival in a Large National Cohort of Patients With Diabetes and Cirrhosis

BACKGROUND & AIMS

Type II diabetes mellitus worsens the prognosis of cirrhosis. Multiple medications including metformin and statins often are co-administered to manage patients with diabetes. The aim of this study was to assess the impact of metformin exposure on mortality, hepatic decompensation, and hepatocellular carcinoma in individuals with diabetes and cirrhosis, controlling for multiple concomitant exposures.

METHODS

We performed a retrospective cohort study of patients with cirrhosis diagnosed between January 1, 2008, through June 30, 2016, in the Veterans Health administration. Marginal structural models and propensity-matching approaches were implemented to quantify the treatment effect of metformin in patients with pre-existing diabetes with or without prior metformin exposure.

RESULTS

Among 74,984 patients with cirrhosis, diabetes mellitus was present before the diagnosis of cirrhosis in 53.8%, and was diagnosed during follow-up evaluation in 4.8%. Before the diagnosis of cirrhosis, 11,114 patients had active utilization of metformin. In these patients, metformin, statin, and angiotensinogen-converting enzyme inhibitor/angiotensin-2-receptor blocker exposure were associated independently with reduced mortality (metformin hazard ratio, 0.68; 95% CI, 0.61-0.75); metformin was not associated with reduced hepatocellular carcinoma or hepatic decompensation after adjustment for concomitant statin exposure. For patients with diabetes before a diagnosis of cirrhosis but no prior metformin exposure, metformin similarly was associated with reduced mortality (hazard ratio, 0.72; 95% CI, 0.35-0.97), but not with reduced hepatocellular carcinoma or hepatic decompensation.

CONCLUSIONS

Metformin use in patients with cirrhosis and diabetes appears safe and is associated independently with reduced overall, but not liver-related, mortality, hepatocellular carcinoma, or decompensation after adjusting for concomitant statin and angiotensinogen-converting enzyme inhibitor/angiotensin-2-receptor blocker exposure.

Longitudinal changes in physical and mental health of older adults with chronic hepatitis B infection: Trajectories and predictors

Despite the increasing health burden of chronic hepatitis B (CHB) in aging populations, little is known about the course of health-related quality of life (HRQoL) changes. We aimed to assess individual-level longitudinal HRQoL changes in elderly patients with CHB and to examine their correlates. A prospective 5.1 years-cohort study was conducted in community-dwelling adults aged 55 years with hepatitis B surface antigen-positive. Participants underwent serial measurement of HRQoL using the short-form (12) health survey version 2. Of 503 participants, 82.7% remained in good physical health throughout the study period, whereas 9.1% had declining physical health and 8.2% were in poor physical health. We likewise identified three trajectories of mental health changes ("good mental health" [86.9%], "declining mental health" [6.8%], and "poor mental health" [6.4%]). Three baseline characteristics were independently associated with a lower likelihood of remaining physically or mentally healthy: sarcopenic obesity (odds ratio [OR] with 95% confidence interval [95% CI] of 7.5 [2.8-20.5] for poor physical health, 3.1 [1.1-8.4] for declining physical health, 4.3 [1.4-13.0] for poor mental health), a higher number of metabolic abnormalities (OR [95% CI] of 3.6 [1.6-8.0] for poor physical health) and depressed mood (OR [95% CI] of 21.7 [5.8-81.0] for poor physical health, 5.3 [1.4-19.9] for declining physical health, 83.1 [19.7-350.2] for poor mental health, 13.6 [2.9-64.8] for declining mental health). In conclusion, in a cohort of elderly patients with CHB, we demonstrated the heterogeneity and nonlinearity of HRQoL changes and their associations with variations in specific extrahepatic organs/systems.

Significantly Decreased Islet β Cell Function is Closely Associated with Hyperglycemia in Chronic Hepatitis B Patients

AIM

This study is aimed at the characteristics of glucose metabolism and islet β cell function evaluated by the homeostasis model assessment of β cell function (HOMA-β) value and its risk factors in chronic hepatitis B (CHB) patients.

METHOD

This cross-sectional study recruited 110 CHB patients (CHB group) and 110 patients without hepatitis B virus (non-HBV group); the groups were matched according to sex, age, and body mass index under the same glucose metabolism status. The risk factors, characteristics, and differences in glucose metabolism and HOMA-β values between the two groups were analyzed.

RESULTS

The abnormal glucose metabolism rate was higher in CHB patients with liver cirrhosis (LC) or hepatitis B envelope antigen (HBeAg) (-) status. In addition, under the same glucose metabolism status, the fasting plasma glucose (FPG) levels and 2-hour postprandial plasma glucose (2h-PG) levels in the CHB group were higher, while the HOMA-β values were significantly lower and the homeostasis model assessment of insulin resistance (HOMA-IR) value was not higher than that in the non-HBV group (all P < 0.0001). Further analyses revealed that the main risk factors for abnormal glucose metabolism were HBeAg (-) status and hepatitis B envelope antibody levels. But HBV serological and virological indicators had no effects on the HOMA-β values.

CONCLUSION

Islet β cell function in patients with CHB was compromised, which is closely associated with fasting and postprandial hyperglycemia in chronic hepatitis B patients. Further research should be done to verify the compromised islet β cell function and then to investigate the mechanisms behind the effect of hepatitis B virus infection on islet β cell function in CHB patients.

External Validation of aMAP Hepatocellular Carcinoma Risk Score in Patients With Chronic Hepatitis B-Related Cirrhosis Receiving ETV or TDF Therapy

Background and Aim: A prediction model of hepatocellular carcinoma (HCC) risk in patients with chronic liver diseases, based on age, male sex, albumin-bilirubin, and platelets (aMAP), has been previously reported. We validated the aMAP score and compared its performance to those of other risk scores in an independent at-risk cohort.

Methods: Treatment-naïve patients with chronic hepatitis B-related compensated cirrhosis who received entecavir or tenofovir monotherapy for at least 12 months were enrolled in this study. The performances of the aMAP and other HCC risk scores were assessed using Harrell's c-index, and predefined cut-off values were evaluated using survival analysis.

Results: Of the 1,042 patients, 131 (12.6%) developed HCC during a median follow-up of 41 months. The aMAP score provided the highest Harrell's c-index (0.724), followed by CAMD (0.719), mPAGE-B (0.719), and PAGE-B (0.695). The 5-year cumulative HCC probabilities were 2.9% for patients with a low aMAP score (<50), 11.2% for patients with an intermediate aMAP score (50–60), and 27.9% for patients with a high aMAP score (>60). Using both aMAP and mPAGE-B, 11.6% of patients were identified as low risk with a negative predictive value of 98.2% for not developing HCC within 5 years. Patients with aMAP >60 and diabetes exhibited an extremely high risk of HCC, with a cumulative incidence of 49.3% at 5 years. The predictive performance of aMAP with a reassessment at 1 year after the initiation of antiviral therapy outperformed the predictive performance of aMAP at enrollment.

Conclusions: The aMAP score accurately predicted the risk of HCC in at-risk patients with compensated cirrhosis undergoing antiviral therapy. A combination of the aMAP score and diabetes status could further stratify the risk of HCC.

Effect of type 2 diabetic mellitus in the prognosis of acute-on-chronic liver failure patients in China

BACKGROUND

Acute-on-chronic liver failure (ACLF) patients have a high short-term mortality rate, and the severity evaluation of ACLF is necessary for prognostication. Therefore, it was meaningful to evaluate the association between type 2 diabetic mellitus (DM) and ACLF and further explore the feasibility of using DM as a prognostic indicator in ACLF patients. The association between type 2 DM and the prognosis of patients with severe liver disease remains unclear.

AIM

To examine the effect of type 2 DM on the prognosis of patients with ACLF.

METHODS

Clinical data from 222 ACLF patients were collected and analyzed. The patients were categorized into two groups depending on whether they had DM or not, and the clinical data of ACLF patients were measured within 48 h after admission. Complications of ACLF were documented during treatment, such as hepatic encephalopathy, hepatorenal syndrome, acute upper gastrointestinal hemorrhage, and spontaneous peritonitis (SBP). Values of laboratory parameters, complication rates, and hospital mortality rates were compared between two groups.

RESULTS

Among 222 ACLF patients, 38 cases were categorized into DM groups, the mean age was 56.32 years and 73.68% were male. The prognosis of ACLF patients was significantly correlated with DM in univariate [hazard ratio (HR) = 2.4, 95% confidence interval (CI) =1.5-3.7, P < 0.001] and multivariable analysis (HR = 3.17, 95%CI =1.82-5.523, P < 0.001). The incident of SBP (34.21% vs 13.59%, P = 0.038) and other infections like lung, urinary, blood, and cholecyst (44.74% vs 28.26%, P = 0.046) were higher in DM patients than non-DM counterparts. In addition, the ACLF patients with DM tended to have a high mortality rate (P < 0.001). Cumulative survival time was also significantly shorter in the ACLF patients with DM than non-DM.

CONCLUSION

A significant association between DM and the prognosis of ACLF patients was found in China. The ACLF patients with DM had higher incidence of hospital mortality and infection than those without DM.

Chronic inflammation involves CCL11 and IL-13 to facilitate the development of liver cirrhosis and fibrosis in chronic hepatitis B virus infection

The pathogenesis involving non-alcoholic fatty liver disease (NAFLD) in the context of chronic HBV (CHB) virus infection requires to be understood for developing improved modalities of diagnosis and treatment. We retrospectively investigated the association between NAFLD and CHB virus infection in the context of liver fibrosis. Among the 522 consecutive CHB patients who underwent transient elastography between years 2013 and 2016, we studied 455 subjects in the current investigation. Controlled attenuation parameter (CAP) and liver stiffness measurement (LSM) scores were generally higher in patients with steatosis and fibrosis or cirrhosis. Antiviral treatment had significantly reduced the hepatitis B virus (HBV) viral load. Other liver function markers showed a significant positive correlation with both CAP and LSM scores. Plasma IL-13 was independently associated with increased CAP score where every increase of 1 unit of IL-13 was associated with an increase in CAP score by 0.98 unit. CCL11 was independently associated with LSM with every increase of CCL11 by a unit that, in turn, was associated with an increase of LSM score. We found that there was a high concurrence of NAFLD among patients with CHB virus infection. The presence of metabolic syndrome and chronic inflammation in CHB virus-infected patients were two independent factors that led to the progression of liver cirrhosis, with IL-13 playing the key role in linking the metabolic with the inflammatory components.

Diabetes mellitus affects long-term survival in hepatitis B virus-related hepatocellular carcinoma patients: A propensity score-matched analysis

Diabetes mellitus (DM) increases the risk of developing hepatocellular carcinoma (HCC), and how DM affects the prognosis of HCC have not been elucidated. The aim of this study was to compare clinicopathological characteristics and survival between hepatitis B virus (HBV)-related HCC patients with and without DM and to determine risk factors for overall survival after hepatectomy.Among 474 patients with HBV-related HCC, 119 patients had DM. Patients were divided into the diabetic group and nondiabetic group. The short-term and long-term outcomes were evaluated by using propensity score matching analysis.After 1:2 propensity score matching, there were 107 patients in diabetic group, 214 patients in nondiabetic group. The proportion of vessels invasion were higher in diabetic group. The overall survival rate in the diabetic group was 44.7% at 3 years, which was lower than that in the nondiabetic group (56.1%, P = .025). The multivariate analysis indicated that fasting blood glucose >7.0, capsular invasion, microvascular invasion and satellite were independent risk factor of poor prognosis in HCC.DM dose affect the recurrence-free survival and overall survival in HBV-related HCC patients after hepatectomy. One of the more significant findings to emerge from this study is that DM induced higher proportion of major vessel invasion in HCC patients implied unfavorable prognosis.

Chronic hepatitis B-associated liver disease in the context of human immunodeficiency virus co-infection and underlying metabolic syndrome

Globally, a shift in the epidemiology of chronic liver disease has been observed. This has been mainly driven by a marked decline in the prevalence of chronic hepatitis B virus infection (CHB), with the greatest burden restricted to the Western Pacific and sub-Saharan African regions. Amidst this is a growing burden of metabolic syndrome (MetS) worldwide. A disproportionate co-burden of human immunodeficiency virus (HIV) infection is also reported in sub-Saharan Africa, which poses a further risk of liver-related morbidity and mortality in the region. We reviewed the existing evidence base to improve current understanding of the effect of underlying MetS on the development and progression of chronic liver disease during CHB and HIV co-infection. While the mechanistic association between CHB and MetS remains poorly resolved, the evidence suggests that MetS may have an additive effect on the liver damage caused by CHB. Among HIV infected individuals, MetS-associated liver disease is emerging as an important cause of non-AIDS related morbidity and mortality despite antiretroviral therapy (ART). It is plausible that underlying MetS may lead to adverse outcomes among those with concomitant CHB and HIV co-infection. However, this remains to be explored through rigorous longitudinal studies, especially in sub-Saharan Africa. Ultimately, there is a need for a comprehensive package of care that integrates ART programs with routine screening for MetS and promotion of lifestyle modification to ensure an improved quality of life among CHB and HIV co-infected individuals.

Fatty liver is associated with advanced fibrosis but does not predict adverse outcomes in patients with chronic hepatitis B

Hepatic steatosis is increasingly common and has been implicated in progression of liver fibrosis in chronic hepatitis B (CHB) patients. We aimed to investigate the impact of hepatic steatosis on liver fibrosis and clinical outcomes in CHB patients. Consecutive CHB patients who underwent transient elastography between 2013 and 2017 at a tertiary hospital were included in this longitudinal cohort study. Presence of hepatic steatosis was defined as controlled attenuation parameter, CAP ≥ 248 dB/m, while advanced liver fibrosis was defined as liver stiffness measurement, LSM ≥ 9.4 kPa. Cardiovascular events, liver-related complications, malignancy and mortality and a composite of these outcomes were evaluated with Kaplan-Meier analysis and Cox proportional hazards regression. Our study cohort included 614 patients with median follow-up of 45 (32-63) months. Hepatic steatosis was present in 294 patients (47.9%), and advanced liver fibrosis was present in 127 patients (21.0%). Presence of hepatic steatosis (OR: 1.956, 95% CI: 1.250-3.060) and diabetes mellitus (OR: 3.507, 95% CI: 2.069-5.944) was independently associated with advanced fibrosis. Advanced fibrosis was independently associated with composite outcome (HR: 2.496, 95% CI: 1.352-4.606), liver-related complications (HR: 3.765, 95% CI: 1.380-10.271) and mortality (HR: 3.632, 95% CI: 1.342-9.826), but not cardiovascular events and malignancy. Hepatic steatosis was not associated with any adverse outcomes. We conclude that hepatic steatosis is common and associated with advanced fibrosis in CHB patients. Unlike advanced fibrosis, hepatic steatosis does not predict adverse outcomes in CHB patients.

Clinical implications, diagnosis, and management of diabetes in patients with chronic liver diseases

Diabetes mellitus (DM) negatively affects the development and progression of chronic liver diseases (CLD) of various etiologies. Concurrent DM and CLD are also associated with worse clinical outcomes with respect to mortality, the occurrence of hepatic decompensation, and the development of hepatocellular carcinoma (HCC). Unfortunately, early diagnosis and optimal treatment of DM can be challenging, due to the lack of established clinical guidelines as well as the medical complexity of this patient population. We conducted an exploratory review of relevant literature to provide an up-to-date review for internists and hepatologists caring for this patient population. We reviewed the epidemiological and pathophysiological associations between DM and CLD, the impact of insulin resistance on the progression and manifestations of CLD, the pathogenesis of hepatogenic diabetes, as well as the practical challenges in diagnosis and monitoring of DM in this patient population. We also reviewed the latest clinical evidence on various pharmacological antihyperglycemic therapies with an emphasis on liver disease-related clinical outcomes. Finally, we proposed an algorithm for managing DM in patients with CLD and discussed the clinical and research questions that remain to be addressed.

Real-World Effectiveness From the Asia Pacific Rim Liver Consortium for HBV Risk Score for the Prediction of Hepatocellular Carcinoma in Chronic Hepatitis B Patients Treated With Oral Antiviral Therapy

BACKGROUND

Patients on oral antiviral (OAV) therapy remain at hepatocellular carcinoma (HCC) risk. Risk prediction tools distinguishing treated patients with residual HCC risk are limited. The aim of this study was to develop an accurate, precise, simple-to-use HCC risk score using routine clinical variables among a treated Asian cohort.

METHODS

Adult Asian chronic hepatitis B (CHB) patients on OAV were recruited from 25 centers in the United States and the Asia-Pacific region. Excluded persons were coinfected with hepatitis C, D, or human immunodeficiency virus, had HCC before or within 1 year of study entry, or their follow-up was <1 year. Patients were randomized to derivation and validation cohorts on a 2:1 ratio. Statistically significant predictors from multivariate modeling formed the Real-world Effectiveness from the Asia Pacific Rim Liver Consortium for HBV (REAL-B) score.

RESULTS

A total of 8048 patients were randomized to the derivation (n = 5365) or validation group (n = 2683). The REAL-B model included 7 variables (male gender, age, alcohol use, diabetes, baseline cirrhosis, platelet count, and alpha fetoprotein), and scores were categorized as follows: 0-3 low risk, 4-7 moderate risk, and 8-13 high risk. Area under receiver operating characteristics were >0.80 for HCC risk at 3, 5, and 10 years, and these were significantly higher than other risk models (p < .001).

CONCLUSIONS

The REAL-B score provides 3 distinct risk categories for HCC development in Asian CHB patients on OAV guiding HCC surveillance strategy.

Type 2 Diabetes: A Risk Factor for Hospital Readmissions and Mortality in Australian Patients With Cirrhosis

Although there is evidence that type 2 diabetes mellitus (T2D) impacts adversely on liver‐related mortality, its influence on hospital readmissions and development of complications in patients with cirrhosis, particularly in alcohol‐related cirrhosis (the most common etiological factor among Australian hospital admissions for cirrhosis) has not been well studied. This study aimed to investigate the association between T2D and liver cirrhosis in a population‐based cohort of patients admitted for cirrhosis in the state of Queensland, Australia. A retrospective cohort analysis was conducted using data from the Queensland Hospital Admitted Patient Data Collection, which contains information on all hospital episodes of care for patients with liver cirrhosis, and the Death Registry during 2008‐2017. We used demographic, clinical data, and socioeconomic characteristics. A total of 8,631 patients were analyzed. A higher proportion of patients with T2D had cryptogenic cirrhosis (42.4% vs. 27.3%, respectively; P < 0.001) or nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (13.8% vs. 3.4%, respectively; P < 0.001) and an admission for hepatocellular carcinoma (18.0% vs. 12.2%, respectively; P < 0.001) compared to patients without T2D. Patients with liver cirrhosis with T2D compared to those without T2D had a significantly increased median length of hospital stay (6 [range, 1‐11] vs. 5 [range, 1‐11] days, respectively; P < 0.001), double the rate of noncirrhosis‐related admissions (incidence rate ratios [IRR], 2.03; 95% confidence interval [CI], 1.98‐2.07), a 1.35‐fold increased rate of cirrhosis‐related admissions (IRR, 1.35; 95% CI, 1.30‐1.41), and significantly lower survival (P < 0.001). Conclusion: Among hospitalized patients with cirrhosis, the cohort with T2D is at higher risk and may benefit from attention to comorbidities and additional support to reduce readmissions.

Epidemiology of non-alcoholic fatty liver disease in Asia

The growing burden of non-alcoholic fatty liver disease (NAFLD) parallels the increasing prevalence of obesity in Asia. The overall prevalence of NAFLD in Asia is now estimated to be 29.6% and may have surpassed that in Western populations. NAFLD increases with increasing age and is closely associated with metabolic syndrome. Ethnic differences exist in the prevalence of NAFLD, but the underlying factors are unclear. There were initial concerns about lean NAFLD being associated with more severe liver disease and increased mortality, but subsequent studies suggested otherwise. Only some NAFLD patients progress to develop advanced liver fibrosis and cirrhosis, while the liver status remains unchanged in the majority; fibrosis stage is the most important predictor of disease-specific mortality in NAFLD. Surveillance for hepatocellular carcinoma (HCC) remains a challenge due to undiagnosed cirrhosis and the development of HCC in non-cirrhotic NAFLD patients. Diabetes mellitus shares a bidirectional relationship with NAFLD; NAFLD is highly prevalent among patients with diabetes mellitus, and diabetes mellitus is associated with more severe NAFLD. Chronic hepatitis B (CHB) is a major cause of chronic liver disease in Asia; NAFLD and CHB are increasingly observed together because of the increasing prevalence of NAFLD. Despite studies reporting favorable virologic outcome in CHB patients with NAFLD, NAFLD has been found to be independently associated with fibrosis progression and poorer prognosis in CHB patients. Therefore, NAFLD in CHB patients should be given more attention.

The double burden of diabetes and global infection in low and middle-income countries

Four out of five people in the world with diabetes now live in low- and middle-income countries (LMIC), and the incidence of diabetes is accelerating in poorer communities. Diabetes increases susceptibility to infection and worsens outcomes for some of the world’s major infectious diseases such as tuberculosis, melioidosis and dengue, but the relationship between diabetes and many neglected tropical diseases is yet to be accurately characterised. There is some evidence that chronic viral infections such as hepatitis B and HIV may predispose to the development of type 2 diabetes by chronic inflammatory and immunometabolic mechanisms. Helminth infections such as schistosomiasis may be protective against the development of diabetes, and this finding opens up new territory for discovery of novel therapeutics for the prevention and treatment of diabetes. A greater understanding of the impact of diabetes on risks and outcomes for infections causing significant diseases in LMIC is essential in order to develop vaccines and therapies for the growing number of people with diabetes at risk of infection, and to prioritise research agendas, public health interventions and policy. This review seeks to give an overview of the current international diabetes burden, the evidence for interactions between diabetes and infection, immune mechanisms for the interaction, and potential interventions to tackle the dual burden of diabetes and infection.

Relationship Between Diabetes Mellitus and Cirrhosis Risk in Chronic Hepatitis B Patients in Wuhan, China

Background

The objective of our research was to assess the possible link between diabetes mellitus (DM) and liver cirrhosis in chronic hepatitis B (CHB) patients in Wuhan, China.

Material/Methods

Individuals with a diagnosis of both liver cirrhosis and chronic HBV infection (n=257), and CHB-only patients (n=514) were matched 1: 2 by age and sex. Demographic, lifestyle, laboratory, and clinical characteristics were reviewed. Univariate and the multiple logistic regression analysis were conducted to investigate the association between DM and HBV-related liver cirrhosis.

Results

The prevalence of DM was higher among CHB patients with liver cirrhosis than in those without liver cirrhosis (22.2% vs. 12.8%, P=0.001), yielding an adjusted odds ratio (AOR) of 2.317 and a 95% confidence interval (CI) of 1.528–3.513. Among them, 87.7% of liver cirrhosis patients were diagnosed with DM before liver cirrhosis diagnosis, yielding an AOR (95% CI) of 2.386 (1.533–3.714). In comparison to patients with a DM duration of 2–5 years, the AOR (95% CI) for those with a DM duration >5 years was 2.073 (0.701–6.132). In DM treatment, the AOR (95% CI) for those treated with insulin was 4.746 (1.329–16.949).

Conclusions

DM was associated with cirrhosis risk in CHB patients in Wuhan, China.

Effect of Non-alcoholic Fatty Liver Disease on Transaminase Levels and Transient Elastography in Patients with Chronic Hepatitis B

Objective To investigate the effects of non-alcoholic fatty liver disease on aminotransferase (ALT) levels and transient elastography in patients with chronic hepatitis B (CHB). Methods A cross-sectional study of 230 patients with CHB and ALT levels up to two times the upper limits of normal, of one-year duration, from June 2018 to May 2019. The demographic, clinical, and laboratory characteristics of each patient were collected. Transient elastography was performed to evaluate controlled attenuation parameter (CAP or steatosis) and liver stiffness (fibrosis). Results A total of 161 (70%) patients were overweight, with over two-thirds (166; 72.2%) having elevated ALT >35 U/L. Three-fourths of the patients (178; 77.4%) had a hepatitis B virus (HBV) deoxyribonucleic (DNA) level of less than 2000 IU/ml. Steatosis was detected in 166 (72.2%) patients while fibrosis of F2 or more in 88 (38.3%). Multivariate regression analysis showed that weight, homeostatic model assessment of insulin resistance (HOMA-IR), and elevated ALT levels of more than 35 were independently associated with higher CAP values (p= 0.019, 0.001, and 0.004, respectively). Age, insulin levels, and platelet counts were independently associated with liver elasticity (p=0.00, 0.002, and 0.028, respectively). HBV DNA levels did not show any significant association with CAP score, liver stiffness, and HOMA-IR or ALT level. Among those with an elevated ALT of 35 or above (n=166), 124 patients had HBV DNA levels less than 2000 IU/ml. Out of these, 97 (78.2%) patients had steatosis and 51 (41.1%) had F2 or more fibrosis. Conclusion A significant number of patients with CHB with mildly elevated ALT levels are overweight, have significant steatosis and fibrosis, but low HBV DNA levels. This aspect is important while making decisions regarding hepatitis B treatment.

The Association Between Decompensated Liver Cirrhosis and Deep Neck Infection: Real-World Evidence

BACKGROUND

Deep neck infection (DNI) can progress to become a life-threatening complication. Liver cirrhosis, which is related to poor immune conditions, is a likely risk factor for DNI. This study investigated the risk and mortality of DNI in patients with decompensated liver cirrhosis (DLC).

METHODS

We performed a nationwide cohort study using the National Health Insurance Research Database (NHIRD) in Taiwan. We included a total of 33,175 patients with DLC between 2000 and 2013, from the Catastrophic Illness Patient Database, a subsection of the NHIRD, along with 33,175 patients without cirrhosis who were matched in a 1:1 proportion for age, sex, and socioeconomic status. The occurrence of DNI was the primary study outcome. The risk, treatment, and mortalities of DNI were evaluated in the study and comparison cohorts.

RESULTS

DLC Patients had a significantly higher incidence of DNI than noncirrhotic patients (p < 0.001). The adjusted Cox proportional hazard regression showed that DLC was associated with a significantly higher risk of DNI (adjusted hazard ratio, 4.11; 95% confidence interval, 3.16-5.35, p < 0.001). The mortality rate in cirrhotic patients with DNI was not significantly higher than that in noncirrhotic patients with DNI (11.6% vs. 9.8%; p = 0.651).

CONCLUSIONS

This study is the first to investigate the correlation between DLC and DNI. The study findings strongly indicate that DLC is an independent risk factor for DNI. Cirrhotic patients with DNI do not have a significantly poorer survival rate than noncirrhotic patients with DNI. Therefore, physicians should be alert to potential DNI occurrence in DLC patients. Besides this, intensive care and appropriate surgical drainage can yield similar survival outcomes in DLC-DNI and noncirrhosis-DNI patients.

Diabetes mellitus increases the risk of hepatic encephalopathy after a transjugular intrahepatic portosystemic shunt in cirrhotic patients

OBJECTIVE

The aim of this study was to examine the effect of diabetes mellitus (DM) on the rate of hepatic encephalopathy (HE) in patients with decompensated liver cirrhosis after the creation of a transjugular intrahepatic portosystemic shunt (TIPS).

PATIENTS AND METHODS

This study retrospectively reviewed 436 consecutive patients with cirrhosis receiving TIPS in our department from 2008 to 2016. By comparing two groups of patients, with or without DM, the incidence of developing overt HE after TIPS, as well as the correlation between diabetes and HE, was analyzed. Data were analyzed using the χ-tests, unpaired t-tests, logistic regression, and Kaplan-Meier curves. After the initial data processing, we used a regression model to analyze whether or not DM is associated with the development of HE after TIPS.

RESULTS

Of the 436 patients who underwent TIPS, 85 (19.5%) had diabetes at admission and 126 (28.9%) had HE after TIPS. Patients with DM more frequently had HE compared with those without DM (44.7 vs. 25.1%; P = 0.000). The logistic regression analysis showed that DM (P = 0.015) and age (P = 0.002) were independent risk factors for HE after TIPS. Finally, using the Kaplan-Meier curves, we found that diabetes significantly increases the incidence of overt HE (log-rank P = 0.026).

CONCLUSION

Similar to old age, DM may increase the risk of HE in cirrhotic patients after the creation of TIPS.

Diabetes Mellitus and Risk of Hepatic Fibrosis/Cirrhosis

Development of cirrhosis is two- to threefold greater in patients with diabetes mellitus (DM), and in this setting, the prevalence of cirrhosis is surging worldwide. The present review served to examine clinical ties between DM and liver fibrosis and hepatic cirrhosis and explore related biologic mechanisms. Pathways contributing to various etiologies of cirrhosis in conjunction with DM were key investigative targets.

Stratification of hepatocellular carcinoma risk through modified FIB-4 index in chronic hepatitis B patients on entecavir therapy

BACKGROUND AND AIM

Noninvasive fibrosis indices can predict the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). Modified FIB-4 (mFIB-4) is a promising noninvasive index for predicting liver fibrosis. To investigate the predictive accuracy of several extant noninvasive fibrosis indices, including mFIB-4, for HCC incidence in CHB patients receiving long-term entecavir therapy.

METHODS

We enrolled 1325 nucleos(t)ide analogue-naïve CHB patients (noncirrhotic 844; cirrhotic 481) treated with entecavir. Baseline clinical features and fibrosis indices were collected and evaluated for predicting HCC risk through univariate and multivariate Cox regression analyses.

RESULTS

Of the 1325 patients, 105 (7.9%) developed HCC during a median follow-up period of 4.1 years. Age (hazard ratio [HR], 1.039; 95% confidence interval [CI], 1.020-1.059; P < 0.0001), diabetes mellitus (DM) (HR, 1.902; 95% CI, 1.185-3.052; P = 0.0077), and mFIB-4 (HR, 4.619; 95% CI, 1.810-11.789; P = 0.0014) were independent predictors of HCC in all patients (mFIB-4 ≥ 1.5 for the noncirrhotic cohort; DM and mFIB-4 ≥ 2.0 for the cirrhotic cohort). A combination of mFIB-4 and the DM status stratified the cumulative risk of HCC into three subgroups in all patients (high: mFIB-4 ≥ 1.5/DM; intermediate: mFIB-4 ≥ 1.5/non-DM; and low: mFIB-4 < 1.5, P < 0.0001) and in the cirrhotic cohort (high: mFIB-4 ≥ 2.0/DM; intermediate: mFIB-4 ≥ 2.0/non-DM; and low: mFIB-4 < 2.0, P = 0.0007). An mFIB-4 cutoff value of 1.5 stratified the cumulative risk of HCC in the noncirrhotic cohort (P = 0.015).

CONCLUSIONS

The mFIB-4 index alone or in combination with DM is the optimal noninvasive predictor of HCC risk in CHB patients receiving entecavir therapy.

Chronic hepatitis B and metabolic risk factors: A call for rigorous longitudinal studies

Long-term nucleos(t)ide analogue therapy in chronic hepatitis B virus (HBV) infection is effective in suppressing viral replication and reducing liver-related complications. However, HBV-related liver events can still occur in different patient sub-groups. There is emerging evidence that, similar to chronic hepatitis C virus infection, metabolic risk factors may play a role in the disease process of chronic HBV. While the mechanistic nature of metabolic-HBV interactions remains uncertain, studies in different HBV-infected populations have demonstrated that hepatic steatosis, increased body-mass index, diabetes, or a combination of different metabolic risk factors are associated with an increased risk of hepatocellular carcinoma and cirrhosis. The impact of metabolic risk factors is especially prominent in patients with quiescent virological activity, including on-treatment patients with effective viral suppression. As the proportion of on-treatment chronic HBV patients increases worldwide, longitudinal studies determining the relative risks of different metabolic parameters with respect to clinical outcomes are needed. Future studies should also determine if metabolic-directed interventions can improve disease outcomes in chronic HBV.

The changing epidemiology of liver diseases in the Asia-Pacific region

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.

Managing diabetes and liver disease association

There is strong association between liver diseases and diabetes (DM) which is higher than expected by a chance association of two very common disorders. It can be classified into three categories: Liver disease related to diabetes, hepatogenous diabetes (HD), and liver disease occurring coincidentally with DM. The criteria for the diagnosis of diabetes associating liver disease are the same for primary diabetes. Two hours post glucose load is a better screening test for HD. HbA1c may not be suitable for diagnosis or monitoring of diabetes associating advanced liver disease. Apart from the increased cardiovascular risk in patients with type 2 DM (T2 DM) and NAFLD, the cardiovascular and retinopathy risk is low in HD. Patients with metabolic derangement should be screened for NAFLD which in turn may predict T2 DM development. Similarly, patients with established T2 DM should also be screened for NAFLD which further contributes to diabetes worsening. Diabetes is a significant risk factor for progression of the chronic liver disease. It is associated with poor patient survival. Treatment of diabetes associating liver disease appears beneficial. Metformin, if tolerated and not contraindicated, is recommended as a first-line therapy for patients with diabetes and chronic liver disease (CLD). If the hepatic disease is severe, insulin secretagogues should be avoided because of the increased risk of hypoglycaemia. Pioglitazone may be useful in patients with fatty liver disease. DPP-4 inhibitors showed effectiveness and safety for the treatment of T2 DM in CLD patients up to those with child B stage. GLP-1 receptor agonists and SGLT-2 inhibitors exhibit positive effects on weight and are associated with minimal risk of hypoglycaemia. Insulin must be used with caution, as hypoglycaemia may be a problem. Insulin analogues are preferred in the context of hypoglycaemia Statins can be used to treat dyslipidaemia in NAFLD, also the use of angiotensin II receptor antagonist for hypertension is safe and beneficial Given the clear association between diabetes mellitus and hepatocellular carcinoma, the strict control of glycaemia with insulin sensitizers can be essential in its prevention. The addition of DM to the currently used scores (Child-Pugh and MELD scores) may enhance the sensitivity and the specificity for prediction of morbidity and mortality rates in cirrhotic patients. In the new era of directly acting antiviral agents (DAAs) for HCV treatment, it is recommended to follow up lipid profile and blood sugar levels following SVR in order to adjust doses of medications used in diabetic (SVR is associated with reduction in insulin requirements) and dyslipidaemic patients (rebound increase in the lipid profile after clearing the virus may increase risk of cardiovascular disease (CVD)). The issues of post liver transplant diabetes and relation between DM and chronic HBV are highlighted. This narrative review and Consensus-based practice guidance (under revision and criticism) are based on a formal review and analysis of the recently published world literature on the topic (Medline search up to September 2017); and the experience of the authors and independent reviewers.

Prevalence of serological markers for hepatitis and potential associated factors in patients with diabetes mellitus

Objective:

to estimate the prevalence of serological markers for hepatitis B and C in patients with diabetes mellitus and analyze potential associated factors.

Method:

a cross-sectional study with 255 patients with diabetes mellitus. Demographic, clinical, and risk behavior factors for hepatitis B and C were selected. The markers HBsAg, Anti-HBc IgG, Anti-HBc IgM, Anti-HBs, and Anti-HCV were investigated. A questionnaire and venous blood collection and inferential statistical analysis were used.

Results:

16.8% of the patients had a total reactive Anti-HBc marker, 8.2% an isolated Anti-HBs, and 75% were non-reactive for all hepatitis B markers. No case of reactive HBsAg was found and 3.3% of the patients had a reactive anti-HCV marker. The prevalence of prior hepatitis B virus infection was directly associated with the time of diabetes mellitus and the prevalence of hepatitis C virus infection was not associated with the investigated variables. The prevalence of hepatitis B and C infection in patients with diabetes mellitus was higher when compared to the national, with values of 16.8% and 3.3%, respectively.

Conclusion:

the results suggest that patients with diabetes are a population of higher vulnerability to hepatitis B and C, leading to the adoption of preventive measures of their occurrence.

Chronic hepatitis B virus infection

Chronic hepatitis B virus infection is a global public health threat that causes considerable liver-related morbidity and mortality. It is acquired at birth or later via person-to-person transmission. Vaccination effectively prevents infection and chronic hepatitis B virus carriage. In chronically infected patients, an elevated serum hepatitis B virus DNA concentration is the main risk factor for disease progression, although there are other clinical and viral parameters that influence disease outcomes. In addition to liver biochemistry, virological markers, and abdominal ultrasonography, non-invasive assessment of liver fibrosis is emerging as an important assessment modality. Long-term nucleos(t)ide-analogue therapy is safe and well tolerated, achieves potent viral suppression, and reduces the incidence of liver-related complications. However, a need to optimise management remains. Promising novel therapies are at the developmental stage. With current vaccines, therapies, and an emphasis on improving linkage to care, WHO's goal of eliminating hepatitis B virus as a global health threat by 2030 is achievable.

A combination of the on-treatment FIB-4 and alpha-foetoprotein predicts clinical outcomes in cirrhotic patients receiving entecavir

BACKGROUND & AIMS

This study investigates the long-term incidences and predictors of developing hepatocellular carcinoma (HCC), cirrhotic events and mortality in cirrhotic patients receiving entecavir (ETV) therapy.

METHODS

We enrolled 481 nucleos(t)ide analogue-naïve chronic hepatitis B (CHB) patients who had compensated cirrhosis upon entry and had received ETV monotherapy for >12 months.

RESULTS

The 8-year cumulative incidences of developing HCC, cirrhotic events and liver-related mortality were 26.5%, 8.62% and 10.03% respectively. Multivariate analysis revealed that diabetic mellitus (DM), higher fibrosis-4 (FIB-4) and alpha-foetoprotein (AFP) levels at 12 months of treatment, and FIB-4 increase from baseline to 12 months were independent factors of HCC. FIB-4 and AFP levels at 12 months of treatment were also independent factors of cirrhotic events and mortality. FIB-4 cut-off values of 3, 3 and 5 as well as AFP cut-offs of 5, 5, and 9 ng/mL at 12 months of treatment were optimal for predicting HCC, cirrhotic events and mortality during therapy respectively. The FIB-4 and AFP levels at 12 months of treatment were assessed for the combined risk of developing clinical outcomes. The 8-year incidences of HCC, cirrhotic events and liver-related mortality in the subgroups with low FIB-4 and AFP levels were only 5.95%, 1.03% and 2.43% respectively. DM was an independent predictor of HCC and mortality.

CONCLUSION

The combination of FIB-4 and AFP levels at 12 months of treatment is a useful marker for predicting the development of HCC, cirrhotic events and mortality in compensated cirrhotic patients with CHB who are receiving ETV therapy.

Effect of Metabolic Syndrome on the Clinical Outcomes of Chronic Hepatitis B Patients with Nucleos(t)ide Analogues Treatment

BACKGROUND

No data are available about the effect of MS on oral nucleos(t)ide analogues (NUCs) treatment and clinical outcomes in chronic hepatitis B (CHB) patients.

AIMS

We aimed to elucidate whether coexistence of MS and CHB affects the long-term prognosis of CHB patients with oral NUCs treatment.

METHODS

We performed a retrospective data analysis for a total of 587 CHB patients who started oral NUCs treatment for the first time in our institution from January 2006 to March 2016.

RESULTS

Among the 587 patients, 70 (11.9%) had MS, but 517 (88.1%) had no evidence of MS when oral NUCs treatment was initiated. Cumulative occurrence rates of viral breakthrough, genotypic resistance, HCC, disease progression (PD), and overall adverse outcomes (OAO) were significantly higher in CHB patients with MS than in those without MS, although HBV-DNA suppression and cumulative occurrence rates of HBeAg negative conversion and seroconversion were not significantly different between the two groups. The overall survival (OS) was also significantly shorter in CHB patients with MS than in those without MS. Multivariate analysis indicated that the MS was an independent, poor prognostic factor for occurrence of genotypic resistance (adjusted hazard ratio [aHR], 22.3; 95% confidence interval [CI] 6.61-75.02; P < 0.001), HCC (aHR, 3.98; 95% CI 2.07-7.66; P < 0.001), PD (aHR, 6.18; 95% CI 3.43-11.14; P < 0.001), OAO (aHR, 8.10; 95% CI 4.68-14.02; P < 0.001), and OS (aHR, 12.29; 95% CI 2.25-67.24; P < 0.001).

CONCLUSIONS

MS is an independent determinant of poor prognosis in CHB patients receiving oral NUCs treatment.

Long-term Nucleos(t)ides Analogues for Chronic Hepatitis B Improve Liver and Spleen Size: A Noninvasive Sonographic Study

Background:

Histological improvement and regression of liver fibrosis after long-term use of nucleos(t)ides analogues (NUCs) have been documented. The aim of the present investigation was to evaluate the usefulness of traditional sonography to detect hepatic and splenic changes during NUC therapy in chronic hepatitis B (CHB) patients.

Methods:

A total of 181 CHB patients receiving NUC treatment were enrolled in this study. The study population was divided into three groups 72 cirrhotic, 58 noncirrhotic CHB, and 51 nonreplicative hepatitis B virus carriers. All patients had blood chemistries taken and sonography at baseline and during the NUC treatment period. The changes in liver size, liver edge, spleen size, platelet count, and platelet count/spleen diameter (PC/SD) ratio were compared among the three groups of patients.

Results:

CHB Patients with and without cirrhosis have improved clinical features during NUC therapy with lower aspartate aminotransferase, alanine aminotransferase, international normalized ratio, hepatitis B virus DNA, and spleen size and higher platelet, liver edge, liver size, and PC/SD ratio compared with the baseline data (p < 0.05). The differences in liver edge, liver size, spleen size, and PC/SD ratio are higher in the cirrhosis group than in the non-cirrhotic group (p < 0.001). A decrease in spleen size exhibited a linear relationship with treatment duration (R² = 0.905).

Conclusions:

Traditional sonography is helpful to monitor changes in liver fibrosis of CHB patients under NUC therapy.

Incidence and prevalence of hepatitis B in patients with diabetes mellitus in the UK: A population-based cohort study using the UK Clinical Practice Research Datalink

We assessed the incidence and prevalence of hepatitis B (Hep B) in patients with or without diabetes mellitus (DM) using the UK Clinical Practice Research Datalink (CPRD). This was a retrospective, observational study of diabetic and nondiabetic cohorts aged 0-80 years using CPRD (NCT02324218). Incidence rates (IR) for each cohort were calculated. Crude and adjusted (Poisson regression) IR ratios (IRR) were estimated with 95% confidence intervals (CI) to compare the cohorts. Hep B prevalence stratified by age, and hospitalization related to Hep B was also calculated. Of 7 712 043 subjects identified, 4 839 770 were included (DM: 160 760; non-DM: 4 679 010). Mean ages were 54.4 and 32.0 years, and 57.20% and 50.14% were male in the diabetic and nondiabetic cohorts, respectively. Hep B was identified in 29 diabetic and 845 nondiabetic subjects; IR was 4.03 per 100 000 person-years and 2.88 per 100 000 person-years, respectively. The adjusted IRR was 1.00 (95% CI: 0.70-1.50) between diabetic and nondiabetic cohorts. Hep B prevalence was higher in the diabetic cohort (0.01%-0.26%) than in the nondiabetic cohort (0.00%-0.03%) across the different age groups. Hep B-associated hospitalization IR was higher in the diabetic cohort (4.98-10.91) than the nondiabetic cohort (0.26-2.44). The Hep B IR, hospitalization and prevalence were higher in males in both cohorts. In conclusion, the risk of incident Hep B diagnosis in the diabetic cohort was not different from that in the nondiabetic cohort. However, prevalence of Hep B and Hep B-associated hospitalization rate was higher in the diabetic than in the nondiabetic cohort.

Association Between Hepatic Steatosis, Measured by Controlled Attenuation Parameter, and Fibrosis Burden in Chronic Hepatitis B

BACKGROUND & AIMS

The interaction between chronic hepatitis B (CHB) and hepatic steatosis is poorly understood. We investigated whether measurement of controlled attenuation parameter (CAP), a non-invasive method to quantify steatosis, can assist in monitoring patients with CHB.

METHODS

We performed transient elastography, to measure liver stiffness, and made CAP measurements in 1606 patients with CHB (898 treated with nucleoside analogues, for a median 75.4 months) in Hong Kong, from January 2015 through September 2016. We also collected information on patients' medical history, current treatment, and smoking and alcohol habits, anthropometric measurements. We obtained and analyzed fasting blood samples. Severe liver fibrosis was defined, according to guidelines, as a liver stiffness measurement greater than 9.0 kPa in patients with normal level of alanine aminotransferase (ALT) or greater than 12.0 kPa in patients with a level of ALT 1-5-fold the upper limit of normal. Steatosis was defined as a CAP measurement of 248 dB/m or more, and severe steatosis as a CAP measurement or 280 dB/m more. We performed multivariate analysis to identify factors associated with severe fibrosis.

RESULTS

The prevalence of steatosis, severe steatosis, and severe fibrosis in our cohort were 40.8%, 22.6%, and 14.1%, respectively. A higher proportion of patients with severe steatosis had severe fibrosis (21.4% vs 11.9% in the overall cohort; P < .001). In multivariate analysis, severe steatosis was associated with severe fibrosis in treatment-naïve patients (odds ratio, 3.60, 95% CI, 1.21-10.75) and in patients receiving treatment (odds ratios: 1.95 [1.06-3.61] for 3 or more years of treatment, 2.28 [1.13-4.61] for 5 or more years of treatment, and 2.79 [1.17-6.62] for 7 or more years of treatment). With every increase in CAP value of 10 dB/m, the risk of severe fibrosis increased by 15% in treatment-naïve patients and by 7%-8% in patients receiving treatment.

CONCLUSIONS

Severe steatosis, determined by CAP measurement, is associated with severe fibrosis in treatment-naïve patients with CHB and in patients receiving treatment. Longitudinal studies are required to investigate if steatosis control, in addition to antiviral treatment, can reduce the burden fibrosis in patients with CHB.

Increasing co-morbidities in chronic hepatitis B patients: experience in primary care and referral practices during 2000-2015

OBJECTIVES

Data on liver and non-liver co-morbidities in chronic hepatitis B (CHB) patients are limited. This study analyzes the prevalence of co-morbidities in a multicenter CHB cohort evaluated over 15 years.

METHODS

This study included 2734 consecutive adult American CHB patients from a university medical center and several community primary care clinics. Data were analyzed by time periods (patients in each time period were unique without overlapping): 2000-2005 (n = 885), 2006-2010 (n = 888), and 2011-2015 (n = 961). Patients were identified via electronic query using diagnosis code with data confirmed and extracted via individual chart review. Most patients were male (57.9%) and Asian (89.6%).

RESULTS

Mean age increased significantly from 43.3 ± 13.4 years during 2000-2005 to 49.1 ± 14.4 during 2011-2015 (p < 0.001). Between 2000-2005 and 2011-2015, fatty liver disease among new CHB patients increased from 1.6 to 6.8% (p < 0.001). Advanced liver diseases also increased (p < 0.001): cirrhosis (12.6-24.6%), hepatic decompensation (1.1-7.9%), and hepatocellular carcinoma (HCC) (4.9-9.1%). Similar trends were observed for non-liver co-morbidities (p < 0.001). Specifically, diabetes increased almost fivefold (4.9-22.9%), hypertension increased threefold (12.3-36.1%) and chronic kidney disease increased 4.5-fold (4.4-19.7%). Prevalence of osteopenia and osteoporosis also increased in CHB patients: 5.4-13.4% (p < 0.001) and 2.9-8.7% (p < 0.001), respectively. These trends were observed in both liver clinics and primary care clinics (except for advanced liver disease), treated and untreated patients, and for both sexes.

CONCLUSIONS

The CHB patient population is aging and now presents with significantly more co-morbidities. Early diagnosis and linkage to care is needed to prevent and mitigate liver as well as non-liver co-morbidities.

Should adults with diabetes mellitus be vaccinated against hepatitis B virus? A systematic review of diabetes mellitus and the progression of hepatitis B disease

Despite the burden of diabetes mellitus (DM), little is known about the role of this and other metabolic syndromes on the severity of hepatitis B virus (HBV) chronicity and liver disease progression. The value of hepatitis B vaccination and its impact on liver diseases and HCC has been largely demonstrated, adult vaccination coverage is however suboptimal and DM diagnosis represents an opportunity for the HCP to discuss hepatitis B and other adult vaccinations.

We performed a systematic literature search to identify studies (January 2000 to January 2017) describing liver disease progression among patients with HBV by DM status. Risk factors were assessed including the relationship between HBV and non-alcoholic steatohepatitis (NASH). Data were extracted systematically and assessed descriptively.

Twenty articles described liver disease progression and one article evaluated NASH among subjects with HBV by DM status. Fourteen articles reported that DM as a predictor for the outcome, including delayed seroclearance, cirrhosis, hepatocellular carcinoma, transplant/mortality and death, whereas no association on liver outcomes was found in 7 studies.

In summary, our review suggests that DM is associated with the progression of severe liver outcomes in adults with HBV, although more studies are needed to understand the benefits of HBV vaccination in adults with DM and liver-diseases.
