Elevated Liver Enzymes in Young Children: What Parents Should Know - Gastroenterology and Hepatology

More Info

---

When it comes to elevated liver enzymes in young children, such as the case of your 3-year-old with an AST (aspartate aminotransferase) level of 49, which is above the normal reference range of 10-42, it is essential to understand the implications and necessary follow-up actions. Elevated liver enzymes can indicate liver inflammation or damage, but they are not definitive on their own.

Understanding Elevated Liver Enzymes
1. What Elevated AST Means: AST is an enzyme found in various tissues, including the liver, heart, and muscles. Elevated levels can suggest liver issues, but they can also be influenced by other factors such as muscle injury or even vigorous physical activity. In children, elevated AST can sometimes be benign and transient, especially if there are no accompanying symptoms.

2. Lymphocytes Count: The lymphocyte count of 60 (normal range 19-48) indicates a higher percentage of lymphocytes, which could suggest a viral infection or an immune response. However, without other symptoms, this might not be a cause for concern.

3. Symptoms and Context: Since your child did not exhibit any symptoms of illness at the time of testing, and considering the recent intake of herbal medicine and potential constipation, these factors could contribute to the elevated enzyme levels. Growth spurts can also cause temporary discomfort, often referred to as "growing pains," which may not be directly related to liver function.


Recommended Actions
1. Follow-Up Testing: It is advisable to follow up with another blood test in about three months, as suggested. This will help determine if the elevated AST is persistent or if it was a transient issue. While it is understandable that young children may be apprehensive about needles, regular monitoring is crucial for their health. You can discuss with your healthcare provider about strategies to make the blood draw less stressful for your child.

2. Monitoring Symptoms: Keep an eye on any new symptoms that may arise, such as jaundice (yellowing of the skin or eyes), abdominal pain, fatigue, or changes in appetite. If any of these symptoms occur, it would be important to seek medical attention sooner.

3. Diet and Lifestyle: Ensure that your child maintains a balanced diet and stays hydrated. Avoid any unnecessary medications or herbal supplements without consulting a pediatrician, as some substances can affect liver function.

4. Consulting with a Specialist: If the follow-up tests continue to show elevated liver enzymes, it may be beneficial to consult a pediatric gastroenterologist or hepatologist. They can provide more specialized care and determine if further diagnostic testing, such as imaging studies or additional blood tests, is necessary.

5. Understanding Growth Patterns: Growth-related discomfort is common in children, but if the leg pain persists or worsens, it may be worth discussing with your pediatrician to rule out other causes.


Conclusion
In summary, while elevated liver enzymes can be concerning, they are not always indicative of a serious problem, especially in the absence of other symptoms. Regular monitoring and follow-up testing are essential to ensure your child's health. Open communication with your healthcare provider will help you navigate this situation effectively and provide the best care for your child.
