Nutritional Therapy in Liver Transplantation

It takes a village: primary care of the pediatric liver transplant recipient

PURPOSE OF REVIEW

Long-term survival is now the rule rather than the exception for infants and children who undergo liver transplantation for end-stage liver disease, metabolic liver conditions and a variety of other indications. Pediatricians and primary care providers play vital roles in the care and management of this patient population. The purpose of this review is to highlight key aspects important to the care of the pediatric liver transplant recipient.

RECENT FINDINGS

Significant advances in immunosuppressive therapies and surgical techniques have contributed to improved graft and patient survival rates, shifting the focus beyond immediate survival to strategies to minimize comorbidities related to long-term immunosuppression during growing years, attend to patient and parent-reported outcomes and enhance quality of life. A multidisciplinary approach allows for monitoring and surveillance of both routine (growth, nutritional rehabilitation, cognitive development, mental and psychosocial health, contraception and daily activities) and transplant-related (adverse effects of immunosuppression, susceptible infections, extra-hepatic systems, transition from childhood to adolescence to adulthood) themes.

SUMMARY

Effective communication between the primary care physician and the transplant team is imperative for optimizing best outcomes. The primary care provider should be aware of the multifacet nature of posttransplant management, which includes medication regimens, common complications and infections.

Management of diabetes mellitus in patients undergoing liver transplantation

Diabetes is a common feature in cirrhotic individuals both before and after liver transplantation and negatively affects prognosis. Certain aetiological agents of chronic liver disease and loss of liver function per se favour the occurrence of pre-transplant diabetes in susceptible individuals, whereas immunosuppressant treatment, changes in lifestyle habits, and donor- and procedure-related factors contribute to diabetes development/persistence after transplantation. Challenges in the management of pre-transplant diabetes include the profound nutritional alterations characterizing cirrhotic individuals and the limitations to the use of drugs with liver metabolism. Special issues in the management of post-transplant diabetes include the diabetogenic potential of immunosuppressant drugs and the increased cardiovascular risk characterizing solid organ transplant survivors. Overall, the pharmacological management of cirrhotic patients undergoing liver transplantation is complicated by the lack of specific guidelines reflecting the paucity of data on the impact of glycaemic control and the safety and efficacy of anti-hyperglycaemic agents in these individuals.

Compromised nutritional status in patients with end-stage liver disease: Role of gut microbiota

BACKGROUND

Patients with end-stage liver disease (ESLD) have a compromised nutritional status because of the liver crucial role in regulating metabolic homeostasis and energy balance.

DATA SOURCES

A systematic review of literature based on extensive relevant articles published from 2001 to 2017 in English in PubMed database was performed by searching keywords such as liver disease, non-alcoholic liver disease, alcoholic liver disease, malnutrition, epigenetics, gut microbiota, and probiotics.

RESULTS

Liver transplantation would be one eligible therapy for ESLD patients, even if, the clinical outcome is negatively influenced by malnutrition and/or infections. The malnutrition is a condition of nutrient imbalance with a high incidence in ESLD patients. An accurate evaluation of nutritional status could be fundamental for reducing complications and prolonging the survival of ESLD patients including those undergoing liver transplantation. In addition, the interaction among nutrients, diet and genes via epigenetics has emerged as a potential target to reduce the morbidity and mortality in ESLD patients. The malnutrition induces changes in gut microbiota causing dysbiosis with a probable translocation of bacteria and/or pathogen-derived factors from the intestine to the liver. Gut microbiota contribute to the progression of chronic liver diseases as well as hepatocellular carcinoma. The administration of probiotics modulating gut microbiota could improve all chronic liver diseases.

CONCLUSIONS

This review provides an update on malnutrition status linked to epigenetics and the potential benefit of some probiotics on the management of ESLD patients. In support of this view and to reveal the constant and growing interest in this field, some clinical trials are reported.

Nutrition and Liver Disease

Malnutrition in children and adults with advanced liver disease represents a tremendous challenge as the nutritional problems are multifactorial. This Editorial comments the articles appearing in this special issue of Nutrients, “Nutrition and Liver disease” dealing with multiple diagnostic and therapeutic features that relate the outcomes of liver disease to nutrition. To improve quality of life and prevent nutrition-related medical complications, patients diagnosed with advanced liver disease should have their nutritional status promptly assessed and be supported by appropriate dietary interventions. Furthermore specific food supplements and/or restriction diets are often necessary for those with hepatic conditions associated with an underlying metabolic or nutritional or intestinal disease.
