Hepatitis B-related acute-on-chronic liver failure induced by hepatotropic viral insult is associated with worse prognosis than that induced by non-virus insult

Determinants of outcomes in patients with hepatitis B virus-decompensated cirrhosis

The role of pre-treatment HBV DNA levels on the prognosis of hepatitis B virus-related decompensated cirrhosis is unclear. This study investigated the effects of pre-treatment HBV DNA and other determinants on short-term and long-term survival of chronic hepatitis B (CHB) patients with decompensated cirrhosis. A total of 278 cirrhotic decompensated CHB patients treated with entecavir or tenofovir disoproxil fumarate were retrospectively enrolled. Cox regression models were used to analyze factors associated with all-cause mortality. The median follow-up time was 17 months (IQR2.17-58.94), during which 132 patients (47.4%) either died or underwent liver transplantation. The cumulative incidence of all-cause mortality was 16%, 29%, 34%, 39%, and 51% at the 1-month, 3-month, 6-month, 1-year, and 5-year follow-ups, respectively. Risk factors associated with 3-month all-cause mortality were age, presence of ascites and hepatic encephalopathy, baseline hepatitis flares, pre-treatment HBV DNA levels, and MELD scores. In the subgroup analysis, for 3-month all-cause mortality, significant associations of age, baseline hepatitis flares, and MELD scores with pre-treatment HBV DNA levels were observed (p for interaction were 0.005, 0.032, and 0.030, respectively). Risk factors associated with 5-year all-cause mortality were age, the presence of ascites and hepatic encephalopathy, and MELD scores. Liver functional reserve and age played a critical role in the prognosis of CHB patients with decompensated cirrhosis. Pre-treatment HBV DNA levels had an impact on short-term all-cause mortality, but not on long-term all-cause mortality.

Etiology and Prognostic Criteria for Liver Failure in Southeast China: A Multicenter Retrospective Cohort Study Between 2018 and 2020

Background: The prognosis of patients with liver failure (LF) depends significantly on the etiology and clinical indicators. This analysis of these basic indicators can help provide a basis for the study of predictive outcome indicators. Methods: We collected the data from multiple centers in Southeast China, including subclasses of acute liver failure (ALF), subacute liver failure (SLF), acute-on-chronic liver failure (ACLF), subacute-on-chronic liver failure (SALF), and chronic liver failure (CLF). Multivariate logistic regression analysis was used to screen for clinical indicators of nonsurvivors. We analyzed receiver operating characteristic (ROC) curves and cutoff values to assess the prognostic criteria. Results: Hepatitis B virus (HBV) infection is the leading etiology of patients with LF (64.52% (411/637)). SALF (41.36%) and CLF (32.30%) are the main subclasses of the hepatitis B virus-related liver failure (HBV-LF) group and the non-HBV-related LF group in Southeast China, respectively. Between 2018 and 2020, the incidence of HBV-LF decreased significantly, ranging from 72.36% to 59.74%, and the spontaneous survival rates of patients with HBV-LF were substantially lower than those of non-HBV-LF patients (36.43%~44.93% vs. 58.97%~63.64%). Infection and cirrhosis were the leading causes of death in both groups. The age and total bilirubin value of the nonsurvivors with HBV-LF were significantly higher, and the number of days of hospitalization was significantly shorter than that of the survivors. The ages of the nonsurvivors in the non-HBV-LF group were significantly higher than those of the survivors. The prothrombin time-international normalized ratio (PT-INR) is 2.05, 1.92, or 2.11, and antithrombin III (AT III) is 24.50%, which are proposed as prognostic criteria for the HBV-SALF (hepatitis B virus-related subacute-on-chronic liver failure), non-HBV-SLF (non-hepatitis B virus-related subacute liver failure), non-HBV-ACLF (non-hepatitis B virus-related acute-on-chronic liver failure), and HBV-ALF (hepatitis B virus-related acute liver failure) subclasses, respectively. Conclusions: The incidence of HBV-LF is decreasing annually. AT III, as an independent prognostic criterion, has excellent discriminative ability for the outcomes of the HBV-ALF subclass.

Effect of SARS-CoV-2 infection on liver function in patients with hepatitis B

OBJECTIVE

To investigate the impact of SARS-CoV-2 infection on liver function and prognosis in patients with HBV infection.

METHODS

A total of 154 HBV-positive patients (HBV ( +) group) and 154 HBV-negative patients (HBV (-) group) diagnosed with COVID-19 at Taizhou Hospital between December 10, 2022, and January 31, 2023, were included in this study. Clinical characteristics, treatment, and laboratory findings were collected from patients at three time points: before (T1), during (T2), and at the time of discharge (T3) from SARS-CoV-2 infection.

RESULTS

Compared to the HBV (-) group, the HBV ( +) group had a longer hospital stay (15 (9-22) days vs. 9 (5-16) days). Longitudinal comparisons of laboratory indicators from T1 to T3 showed a continuous decline in TP and ALB levels and a continuous increase in PT and TT levels in the HBV ( +) group. BUN levels increased during T2 and decreased thereafter. These differences were considered statistically significant (P < 0.05). Notably, the HBV ( +) group had a higher proportion of indicators elevated > 3 ULN from T1 to T2, including ALT (1.95%/5.19%), AST (3.25%/12.99%), ALP (1.95%/3.25%), GGT (4.55%/9.09%), TBIL (6.49%/9.09%), and DBIL (18.18%/22.73%). In the HBV (-) group, the elevations were mainly concentrated within 1-2 ULN, including AST (12.99%/22.08%), DBIL (10.39%/21.43%), BUN (12.99%/22.08%), CREA (20.13%/29.22%), and PLT (7.79%/14.94%). Furthermore, the incidence of liver injury from T1 to T3 was higher in the HBV ( +) group compared to the HBV (-) group (15.7% (20/127) vs. 7.2% (11/152), P < 0.05). Multivariate analysis showed that liver cirrhosis (HR = 4.847, 95% CI: 1.224-19.20, P = 0.025) and liver cancer (HR = 8.333, 95% CI: 2.156-32.209, P = 0.002) were independent risk factors for liver injury in the presence of SARS-CoV-2 infection.

CONCLUSION

SARS-CoV-2 infection has a higher proportion of liver injury in HBV-infected patients, affecting hepatic protein synthesis function. Those with cirrhosis and hepatocellular carcinoma are at higher risk of severe liver injury.

Prevalence of Hepatitis B Virus Markers among the Women with Breast Cancer

INTRODUCTION

Breast cancer represents a formidable peril to the female populace on a worldwide level. The association between breast cancer and various factors, including viral infections, has been extensively investigated. Recently, the link between HBV infection and breast cancer patients has garnered attention. The present research aims to assess the prevalence of HBV markers among women diagnosed with breast cancer in Ahvaz city, Iran.

MATERIALS AND METHODS

Serum specimens were procured from 90 patients who had been clinically diagnosed with breast cancer. The age of the patients ranged from 29 to 80 years, with a mean age of 49.42±10.7. Histological examination of biopsy specimens revealed that 75 (83.33%) were ductal, 11 (8.88%) lobular, 2 (2.22%) mucinous, 1 (1.11%) medullary, and 1 (1.11%) was metastatic. The serum samples were subjected to initial HBsAg and anti-HBc testing via ELISA. Samples that tested seropositive (HBsAg + anti-HBc) were subsequently analyzed for the S region of HBV through nested PCR and DNA sequencing. Finally, a phylogenetic tree was constructed for positive HBV DNA tests.

RESULTS

Among the 5/90 (5.55%) cancer patients, it was found that 3 (3.33%) cases of ductal carcinoma and one (1.11%) lobular carcinoma displayed positivity for HBV markers (HBsAg, anti-HBc, HBV PCR). Notably, one (1.11%) patient with ductal carcinoma solely demonstrated anti-HBc positivity. The phylogenetic tree analysis of the S region revealed that all HBV strains identified were categorized as genotype D.

CONCLUSION

The statistical analysis did not reveal any significant findings (p= 0.315) in the distribution of cancer types across different age groups. Among patients diagnosed with breast cancer, a notable prevalence of 5.5% was observed in HBV markers. The dominant HBV genotype among breast cancer patients was identified as genotype D.

Utility of neutrophil-lymphocyte ratio and platelet-lymphocyte ratio in predicting acute-on-chronic liver failure survival

This study explored the predictive value of the monocyte-to-lymphocyte ratio (MLR) and platelet-lymphocyte ratio (PLR) in patients with acute-on-chronic liver failure (ACLF). A retrospective analysis was carried out on 40 patients with ACLF from January 2018 and August 2019 in our hospital. The patient's clinical information during hospitalization was collected, and their survivals were followed for 3 months. MLR and PLR values of patients were compared, and the correlation between liver function indicators and prognosis was analyzed. We observed that MLR levels in the survival and death groups were 0.521 (0.311, 0.827) and 0.741 (0.442, 1.121), respectively. MLR levels were markedly enhanced in the death group compared to the survival group (P = 0.021). The receiver operating characteristic curve (ROC) exhibited that the area under the ROC curve and 95% confidence interval for the survival group was 0.641 (0.528-0.757). Survival analysis demonstrated that the 3-month survival of the high MLR group was markedly lower than that of the low MLR group (P = 0.001). Multivariate regression exposed that MLR and PLR were independent prognostic factors for ACLF. MLR and PLR could be prospective prognosticative markers of ACLF.

Small-scale spatiotemporal epidemiology of notifiable infectious diseases in China: a systematic review

Background

The prevalence of infectious diseases remains one of the major challenges faced by the Chinese health sector. Policymakers have a tremendous interest in investigating the spatiotemporal epidemiology of infectious diseases. We aimed to review the small-scale (city level, county level, or below) spatiotemporal epidemiology of notifiable infectious diseases in China through a systematic review, thus summarizing the evidence to facilitate more effective prevention and control of the diseases.

Methods

We searched four English language databases (PubMed, EMBASE, Cochrane Library, and Web of Science) and three Chinese databases (CNKI, WanFang, and SinoMed), for studies published between January 1, 2004 (the year in which China’s Internet-based disease reporting system was established) and December 31, 2021. Eligible works were small-scale spatial or spatiotemporal studies focusing on at least one notifiable infectious disease, with the entire territory of mainland China as the study area. Two independent reviewers completed the review process based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results

A total of 18,195 articles were identified, with 71 eligible for inclusion, focusing on 22 diseases. Thirty-one studies (43.66%) were analyzed using city-level data, 34 (47.89%) were analyzed using county-level data, and six (8.45%) used community or individual data. Approximately four-fifths (80.28%) of the studies visualized incidence using rate maps. Of these, 76.06% employed various spatial clustering methods to explore the spatial variations in the burden, with Moran’s I statistic being the most common. Of the studies, 40.85% explored risk factors, in which the geographically weighted regression model was the most commonly used method. Climate, socioeconomic factors, and population density were the three most considered factors.

Conclusions

Small-scale spatiotemporal epidemiology has been applied in studies on notifiable infectious diseases in China, involving spatiotemporal distribution and risk factors. Health authorities should improve prevention strategies and clarify the direction of future work in the field of infectious disease research in China.
