Peri-Operative Stress-Related Cardiomyopathy Following Paediatric Liver Transplant– A Case Series

Perioperative stress-related cardiomyopathy has been extensively described in adults undergoing liver transplantation to be associated with adverse outcomes. Reports of stress-related cardiomyopathy among children is scarce and is usually associated with better clinical outcomes compared to adults. We describe 3 instances of pediatric liver transplantation who developed stress-related cardiomyopathy during the perioperative period and had adverse clinical outcomes. Keywords: Liver Transplantation; Stress-related cardiomyopathy; Heart failure.

NEW IMMUNIZATION SCHEDULE EFFECTIVENESS AGAINST HEPATITIS B IN LIVER TRANSPLANTATION PATIENTS

ABSTRACT BACKGROUND: Although liver transplantation is considered to be a high-risk procedure, it is well-established as a treatment option for the cure and quality of life enhancement for individuals who suffer from diseases. Preventing an infection by hepatitis B virus through immunization schedules has been the most effective way to reduce complications, since it decreases the number of people who suffer from chronic hepatitis caused by the hepatitis B virus and eradicates its transmission. OBJECTIVE: 1. Analyzing evidence in the literature on various schedules employed for immunization against hepatitis B in patients who have received a liver transplantation. 2. Suggesting potential immunization schedules against hepatitis B in patients who suffer from liver cirrhosis, without previous verifying documentation, using the Child-Turcotte Pugh score, according to evidences found in the literature. METHODS: Systematic review of the literature, conducted on the data bases MedLine, PubMed, and Lilacs, between September, 2017 and January, 2018, by using the following keywords: “Liver Transplantation, “Immunization Schedule”, “Hepatitis B Vaccines”. In order to analyze the articles, a summary figure was especially designed and both the results and discussion were presented in a descriptive way. RESULTS: We included 24 studies; among them, eight had accelerated immunization schedules, 13 followed the conventional schedules, and three had super accelerated schedules. Regarding immunization, 21 studies were conducted with patients in the pre-transplant period, one with a transplanted patient, one with a pre-transplant group, and one with a post-transplant group. Found articles suggest that, disregarding the chosen immunization schedule, seroconversion rates tended to be lower as the liver disease advanced, compared to the healthy population. CONCLUSION: The studies did not find seroconversion superiority between the different immunization schedules (conventional and unconventional). However, since candidates to liver transplantation are usually very vulnerable, results show that super accelerated immunization schedules are possibly recommended for such group of patients; serologic test results will be higher when the immunization schedule is completed in the pre-transplant period.

Care of the Liver Transplant Patient

OBJECTIVE: To provide an approach to the care of liver transplant (LT) patients, a growing patient population with unique needs.METHODS: A literature search of PubMed for guidelines and review articles using the keywords “liver transplantation”, “long term complications” and “medical management” was conducted, resulting in 77 articles.RESULTS: As a result of being on immunosuppression, LT recipients are at increased risk of infections and must be screened regularly for metabolic complications and malignancies.DISCUSSION: Although immunosuppression is key to maintaining allograft health after transplantation, it comes with its own set of medical issues to follow. Physicians following LT recipients must be aware of the greater risk for hypertension, diabetes, dyslipidemia, renal failure, metabolic bone disease and malignancies in these patients, all of whom require regular monitoring and screening. Vaccination, quality of life, sexual function and pregnancy must be specifically addressed in transplant patients.
