Comparison of Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) levels before and after parenteral nutrition in critical sick children: Explore the risk of liver damage

Introduction

Critical sick children treated in intensive care rooms often experience malnutrition, both before and during treatment. Therefore, the provision of parenteral nutrition is an option to meet their nutritional needs. However, research shows that the provision of parenteral nutrition has a risk of liver damage, with an incidence reaching 60%. This liver damage can be progressive, irreversible, and even fatal in the long run. Understanding the risk factors associated with parenteral nutrition is crucial in preventing liver damage in critical sick children.

Background

Parenteral nutrition is a type of nutrition therapy that provides essential nutrients to patients who are unable to consume food orally. It is commonly used in intensive care units to support the nutritional needs of critically ill patients. However, research has shown that parenteral nutrition can have a negative impact on liver function, leading to increased levels of liver enzymes such as Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST). The aim of this study is to compare the levels of ALT and AST in critical sick children before and after parenteral nutrition.

Methodology

This study was carried out by analyzing secondary data from the medical records of patients treated in the intensive treatment room and receiving parenteral nutrition in the period July 2018 to July 2021. The study involved 163 samples that received parenteral nutrition, and AST and ALT examination was carried out. Data analysis using paired T test and Wilcoxon Signed Rank test was used to compare the levels of ALT and AST before and after parenteral nutrition.

Results

The results showed an increase in median AST after parenteral nutrition, which reached double the previous value. The average value of ALT before parenteral nutrition was 19.28 ± 6.99 U/L and increased to 42.45 ± 15.41 U/L after parenteral nutrition. The paired t test showed a significant increase in ALT levels after parenteral nutrition, with a p-value of 0.001. These results indicate that parenteral nutrition can lead to increased levels of liver enzymes, which can be a sign of liver damage.

Discussion

Increased levels of ALT and AST indicate damage to liver cells. Although this research does not specifically examine the cause of increased levels of liver enzymes, several factors can be the cause. First, parenteral nutrition can trigger inflammatory responses to the body, which can affect liver function. Second, the composition of parenteral nutrition, especially fat content, can increase oxidative stress in the liver, thus triggering damage to liver cells. Third, the basic conditions of the patient, such as sepsis or organ failure, can also contribute to increased levels of liver enzymes. Understanding the underlying mechanisms of liver damage due to parenteral nutrition is crucial in developing effective strategies to prevent liver damage in critical sick children.

Conclusion

The results of this study provide an important picture of the potential risk of providing parenteral nutrition in critical illness children. Increased levels of ALT and AST after parenteral nutrition should be a concern for doctors and nurses. Strict monitoring of liver function, including examining levels of liver enzymes regularly, is very important to detect liver damage early and prevent serious complications. Further research is needed to understand in depth the mechanism of liver damage due to the provision of parenteral nutrition and to find a more effective solution in minimizing the risk of liver damage in critical sick children who require parenteral nutrition.

Recommendations

Based on the findings of this study, the following recommendations are made:

Regular monitoring of liver function: Doctors and nurses should regularly monitor liver function in patients receiving parenteral nutrition to detect any signs of liver damage early.
Optimization of parenteral nutrition: The composition of parenteral nutrition should be optimized to minimize the risk of liver damage. This can include reducing the fat content and increasing the use of enteral nutrition.
Further research: Further research is needed to understand the underlying mechanisms of liver damage due to parenteral nutrition and to develop effective strategies to prevent liver damage in critical sick children.

Limitations

This study has several limitations, including:

Small sample size: The sample size of this study was relatively small, which may limit the generalizability of the findings.
Retrospective design: The study was retrospective in design, which may limit the ability to establish causality between parenteral nutrition and liver damage.
Limited data: The study only examined the levels of ALT and AST, and did not examine other liver function tests or biomarkers of liver damage.

Future Directions

Future studies should aim to:

Examine the underlying mechanisms of liver damage: Further research is needed to understand the underlying mechanisms of liver damage due to parenteral nutrition.
Develop effective strategies to prevent liver damage: Effective strategies to prevent liver damage in critical sick children who require parenteral nutrition should be developed.
Examine the impact of parenteral nutrition on liver function: The impact of parenteral nutrition on liver function should be examined in more detail, including the effects on liver enzymes and other biomarkers of liver damage.
Frequently Asked Questions (FAQs) about the Comparison of Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) levels before and after parenteral nutrition in critical sick children

Q: What is parenteral nutrition?

A: Parenteral nutrition is a type of nutrition therapy that provides essential nutrients to patients who are unable to consume food orally. It is commonly used in intensive care units to support the nutritional needs of critically ill patients.

Q: What is the risk of liver damage associated with parenteral nutrition?

A: Research has shown that parenteral nutrition can have a negative impact on liver function, leading to increased levels of liver enzymes such as Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST).
