Abstract
This review addresses the vital role of vaccinations in managing patients with chronic liver disease (CLD), especially in the context of the post-COVID-19 landscape. The pandemic has highlighted the unique vulnerabilities of CLD patients, including those awaiting liver transplantation and post-transplant individuals, who face heightened risks of infection due to compromised immune responses. Recent advancements in vaccine technology, such as mRNA platforms, novel adjuvants, and advanced delivery systems, have significantly accelerated vaccine development, enhancing both speed and efficacy. Moreover, the emergence of personalized vaccines, tailored to everyone's unique immunological profile, presents new opportunities, particularly for those with chronic conditions. This review synthesizes the current state of evidence regarding vaccine recommendations for CLD patients, focusing on their response to vaccinations and proposing effective strategies to protect this vulnerable group from vaccine-preventable diseases. It also explores the challenges in implementing these strategies and considers the impact of emerging vaccine delivery systems on improving outcomes for CLD patients. The paper aims to provide nuanced guidance on vaccination in the rapidly evolving healthcare landscape, addressing both technological innovations and comprehensive patient care strategies.

Abstract
Vaccination prevents 2-3 million deaths worldwide every year. Nevertheless, vaccine-preventable diseases (VPDs) still cause a considerable number of deaths especially in subjects belonging to "risk groups." These are represented by older adults, immunocompromised individuals and all subjects with underlying chronic medical conditions (cardiovascular, pulmonary, renal and liver chronic diseases, diabetes, immunodeficiency disorders). They have a weaker immune system and, if infected, are more likely to develop severe complications of their condition or of the preventable-infectious disease. This document summarizes the recommendations for vaccination of the main Global Institutional Organizations and analyses the risks of comorbidities associated with infectious disease and the benefits of vaccination for each specific group. The document provides a clear, practical and authoritative guide to adult vaccination.

Abstract
Purpose of review Patients with cirrhosis are at high risk of developing serious infections. Bacterial infections remain the most common cause of morbidity and mortality in these patients. This review is focused on the prevalence of infections in those with cirrhosis, including multidrug-resistant (MDR) pathogens, pathogenesis of infection-related acute-on-chronic liver failure (ACLF), current treatment recommendations, and prophylactic strategies in patients with cirrhosis. Recent findings Recent epidemiological studies have noted an emerging prevalence of MDR bacterial infections and associated with poor prognosis, and a high rate of treatment failure and mortality. Therefore, new recommendations on empirical antibiotic use based on epidemiological data have been developed in order to improve outcomes. Summary Spontaneous bacterial peritonitis (SBP) and urinary tract infection (UTI) are the most frequent infections followed by pneumonia, cellulitis, and bacteremia, while pneumonia carries the highest risk of mortality. The incidence of MDR bacterial infections has been increasing, especially in healthcare-associated settings. Second infections that develop during hospitalization, multiple organ failures, and high MELD score are associated with poor survival. Preventive measures, early diagnosis, and adequate treatment of infections are essential key concepts in minimizing morbidity and mortality in patients with cirrhosis.

Abstract
Vaccinations against hepatitis A virus (HAV) and hepatitis B virus (HBV) are recommended for patients with chronic liver disease (CLD), yet implementation of these recommendations is lacking. This study reviewed HAV and HBV antibody testing and vaccination status of patients with CLD. In 2008, we began using pre-printed liver order sets, which included vaccination options. We compared Scott & White liver clinic CLD patient records from 2005 (238) with patient records from 2008 (792). Screening rates for immunity and vaccination rates of those lacking immunity were calculated. In 2005, 66% of CLD patients were screened for HAV immunity. In 2008, 56% of CLD patients were screened. The HAV vaccination completion rate was 37% in 2005, while in 2008, the rate was 46%. In 2005, 66% of CLD patients were screened for HBV immunity; in 2008, 56 % CLD patients were screened. The HBV vaccination completion rate was 26% in 2005 compared with 36% in 2008. Although there was a lower percentage of screening in 2008, the overall number of patients tripled between 2005 and 2008. There was a significant increase in the total number of patients screened and vaccinated in 2008. Some physicians may have vaccinated their patients without checking for immunity. In January 2008, we implemented pre-printed order sets with checkboxes to help remind providers to order labs to screen for immunity against HAV and HBV and to order vaccinations for those who lacked immunity. The use of these sets may have aided in the increase of vaccination completion rates.

Vaccinating Adult Patients with Cirrhosis: Trends over a Decade in the United States. Gastroenterol Res Pract 2016; 2016:5795712. [PMID: 27239192 PMCID: PMC4867062 DOI: 10.1155/2016/5795712] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2016] [Revised: 03/23/2016] [Accepted: 04/17/2016] [Indexed: 02/07/2023] Open
Abstract
Introduction. The progression of chronic liver disease to cirrhosis involves both innate and adaptive immune system dysfunction resulting in increased risk of infectious complications. Vaccinations against pneumococcus, hepatitis A virus (HAV), and hepatitis B virus (HBV) are well tolerated and effective in disease prevention and reduction in morbidity and mortality. Prior studies assessing vaccination rates in patients with cirrhosis have specific limitations and to date no study has provided a comprehensive evaluation of vaccination rates in patients with cirrhosis in the United States. Aim. This study assessed vaccination rates for pneumococcus, HAV, and HBV in patients with cirrhosis. Results. Overall 59.7% of patients with cirrhosis received at least 1 vaccination during the study period. Vaccination rates within the same or following year of cirrhosis diagnosis were 19.9%, 7.7%, and 11.0% against pneumococcus, HAV, and HBV, respectively. Trend analysis revealed significant increases in vaccination rates for pneumococcus in all patients with cirrhosis and within subgroups based on age, gender, and presence of concomitant diabetes. Conclusion. The study demonstrated that vaccination rates in patients with cirrhosis remain suboptimal. Ultimately, the use of electronic medical record (EMR) reminders improved communication between healthcare professionals and public health programs to increase awareness are fundamental to reducing morbidity, mortality, and health-care related costs of vaccine preventable diseases in patients with cirrhosis.

Abstract
BACKGROUND Liver transplant recipients are at an increased risk for liver failure when infected with hepatitis A virus (HAV) and hepatitis B virus (HBV). Therefore, it is important to vaccinate these individuals. The aim of the study was to evaluate how well liver transplanted patients in our unit were protected against HAV and HBV infection. Furthermore we investigated the vaccination rate and the antibody response to vaccination in these liver transplanted patients. METHODS Patients liver transplanted from January 2007 until August 2010 with a posttransplant check-up during the period March-November 2010 were included (n = 51). Information considering diagnose, date of transplantation, Child-Pugh score, and vaccination were collected from the patient records. Anti-HAV IgG and anti-HBs titers in serum samples were analyzed and protective levels were registered. RESULTS Of the patients 45% were protected against hepatitis A infection and 29% against hepatitis B infection after transplantation. Only 26% were vaccinated according to a complete vaccination schedule and these patients had a vaccine response for HAV and HBV of 50% and 31%, respectively. An additional 31% received ≥ 1 doses of vaccine, but not a complete vaccination and the vaccine response was much lower among these patients, stressing the importance of completing the vaccination schedule. CONCLUSION Even when patients were fully vaccinated, they did not respond to the same degree as healthy individuals. Patients seemed to be more likely to respond to a vaccination if they had a lower Child-Pugh score, suggesting that patients should be vaccinated as early as possible in the course of their liver disease.

Abstract
Infections are common in patients with chronic liver disease, especially those with cirrhosis. Patients with advanced liver disease, who develop bacterial infections, are at a substantially higher risk of death. As liver disease progresses, most immunizations lose their effectiveness. Overall, it is important to address immunization needs in patients with chronic liver disease early on, when immunizations are most effective. Inactivated or killed-type vaccinations rather than live, attenuated vaccinations are always preferable in patients with cirrhosis. The influenza vaccination is less effective in patients with cirrhosis and in the early post-liver transplant setting as compared to healthy individuals. The influenza vaccination may prevent hepatic decompensation, but further data are needed to confirm this. Yearly inactivated influenza vaccinations should be provided to those with chronic liver disease. The pneumonia vaccination is less effective in patients with cirrhosis, with a further decline in protective serologies after liver transplantation. Standard guidelines for the administration of Pneumovax23 for immunocompromised hosts apply to patients with chronic liver disease. Chronic liver disease also leads to higher non-response rates to the hepatitis B vaccination. Early-stage chronic liver disease patients should receive conventional hepatitis B series. Cirrhotics benefit from a double-dose hepatitis B vaccination at standard intervals. Hepatitis A superimposed on chronic viral hepatitis or chronic liver disease increases risk of mortality. Hepatitis A vaccination effectiveness wanes in cirrhosis, and should if possible be given before the development of cirrhosis. More data are needed for routine use of herpes zoster and human papillomavirus in chronic liver disease.

Abstract
AIM: To study the safety and efficacy of hepatitis A vaccine (HAV) in children with chronic liver disease of various etiologies.
METHODS: Eleven children with chronic liver disease and thirteen age- and sex-matched controls negative for HAV antibodies were vaccinated against hepatitis A after they gave their informed consent. Children with uncontrolled coagulopathy or signs of hepatic decompensation were excluded. The vaccine (Havrix: 720 ELISA units in 0.5 mL, from GlaxoSmithKline Biologicals) was given intramuscularly in the deltoid in 2 doses 6 mo apart. Children were tested for HAV antibodies one and six months after the 1st dose and one month after the 2nd dose. Total serum bilirubin, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were determined immediately before and after one month of the 1st dose of the vaccine.
RESULTS: Only 7 out of the 11 patients were positive for HAV antibodies after the 1st dose of the vaccine, as compared to 100% of the controls. One month after the 2nd dose, all patients tested were positive for HAV antibodies. No deterioration in liver functions of patients was noted after vaccination. No adverse events, immediate or late, were reported by the mothers after each dose of the vaccine.
CONCLUSION: Hepatitis A vaccine is both safe and effective in this small studied group of children with chronic liver disease. Given the high seroconversion rate, post-vaccination testing for HAV antibodies is not needed.

Abstract
Retrospective and prospective studies have demonstrated that the occurrence of acute hepatitis A in patients with chronic liver disease is associated with higher rates of morbidity and mortality than in previously healthy individuals with acute hepatitis A. The mortality associated with acute hepatitis A may be particularly high in patients with preexisting chronic hepatitis C. Although acute hepatitis B in patients with preexisting chronic liver disease is less well studied, worse outcomes than in previously healthy individuals are apparent. However, numerous studies convincingly demonstrate that chronic hepatitis B virus coinfection with hepatitis C virus (or hepatitis D virus) is associated with an accelerated natural history of liver disease and worse outcomes. These observations led to studies that demonstrated the safety and efficacy of hepatitis A and hepatitis B vaccination in patients with mild-to-moderate chronic liver disease. Hepatitis A and B vaccination is less effective in patients with advanced liver disease, especially after decompensation, such as in patients awaiting liver transplantation, and in liver transplant recipients. The emerging lower rates of inherent immunity in younger individuals, higher morbidity and mortality of acute hepatitis A or B superimposed on chronic liver disease, and greater vaccine efficacy in milder forms of chronic liver disease suggest that it is a reasonable policy to recommend hepatitis A and B vaccination in patients early in the natural history of chronic liver disease.

Abstract
Chronic liver disease (CLD) is highly prevalent, and hepatitis C is one of the leading causes. Acute hepatitis A or B in patients with chronic hepatitis C can lead to more severe hepatic injury and a higher fatality rate than in patients without hepatitis C. Thus, the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention and the World Health Organization recommend that persons with CLD be vaccinated against hepatitis A virus (HAV), and the ACIP and the National Institutes of Health recommend vaccination against both HAV and hepatitis B virus (HBV) in patients with chronic hepatitis C. Because coinfection with HAV or HBV in patients with chronic hepatitis C or CLD is common, antibody screening prior to hepatitis A or B vaccination can identify patients who are already immune to these viruses and thus do not need to be vaccinated. Selective hepatitis A vaccination (i.e., vaccination of patients who test negative for either HAV antibody immunoglobulin G or total antibodies to HAV) is most cost-effective in areas where the local prevalence of hepatitis A is higher than the national prevalence and in populations with higher background rates of HAV exposure compared with the general population, such as older adults, foreign-born patients, African Americans, and persons with CLD or hepatitis C. Although not usually recommended for healthy adults or those with compensated CLD because of virtually 100% postvaccination seroconversion, serologic testing after hepatitis A vaccination is recommended in patients with decompensated or advanced end-stage liver disease because of the much lower seroconversion rates in these patients. Selective vaccination against HBV in patients with CLD or hepatitis C is also recommended. Testing for hepatitis B surface antigen (HBsAg) and antibodies to HBsAg (anti-HBs) is considered the most efficient and reasonably cost-effective method to screen for hepatitis B serologic markers because HBsAg identifies individuals with both acute and chronic HBV infection, and anti-HBs identify those who are immune secondary to vaccination or past infection. Testing for antibodies to hepatitis B core antigen is needed to further distinguish between immunity due to vaccination and immunity due to past infection, but it is not recommended as the only screening test for HBV immunity. Postvaccination testing for hepatitis B seroconversion is recommended in all patients with CLD, especially in those with more advanced disease, because the rate of seroconversion is generally lower than in healthy adults. If patients with CLD are not adequately protected after a standard course of hepatitis B vaccination, a repeat course of vaccination using the standard schedule or an accelerated schedule (days 0, 7, and 21) should be considered.

Abstract
Evidence regarding the outcomes of viral super-infection in patients with chronic liver disease and practical strategies for hepatitis A and B vaccination of these individuals are reviewed. Patients with acute hepatitis A and chronic hepatitis B have a more severe clinical course and a higher death rate compared with otherwise healthy individuals with hepatitis A, and these differences are most pronounced in older patients and those with histological evidence of chronic hepatitis or cirrhosis, rather than in asymptomatic hepatitis B carriers. Patients with acute hepatitis A super-infection and chronic hepatitis C have an increased risk of fulminant hepatitis and death. In addition, patients with other chronic liver diseases also appear to be at increased risk for more severe disease with superimposed hepatitis A. Patients with chronic hepatitis B and hepatitis C virus co-infection have more severe laboratory abnormalities, more severe histological disease, a greater frequency of cirrhosis and complications of cirrhosis, and a higher incidence of hepatocellular carcinoma. Vaccines for both hepatitis A and B are safe and effective if used early in the course of chronic liver disease. Hepatitis A and B vaccination should be part of the routine management of patients with chronic liver disease, preferably as early as possible in the natural course of their disease.
