Cerebral changes caused by liver cirrhosis (hepatic encephalopathy)
Hello Doctor, my father has been suffering from cirrhosis for many years.
Last year, he experienced hepatic encephalopathy, and later it was discovered that he has hepatocellular carcinoma (which has been ablated).
He still occasionally shows signs of hepatic encephalopathy, such as slowed movements and increased fatigue.
I would like to ask if there are any other methods to quickly lower ammonia levels in the body besides drinking lactulose? Can we increase the dosage of lactulose on our own, or is it better to take him to the emergency room for ammonia level measurement? Recently, we also noticed that he seems to have developed a twitching at the corner of his mouth.
Could this be related to muscle spasms caused by cirrhosis? He is currently on a three-month follow-up schedule.
Thank you, Doctor.

If necessary, an earlier follow-up appointment can be scheduled.
The dosage of the laxative can be increased to achieve three bowel movements per week, and protein intake should be monitored.
If needed, discuss other strategies with the attending physician.

Managing hepatic encephalopathy (HE) in patients with cirrhosis is a critical aspect of care, especially for those who have experienced complications such as liver cancer. Hepatic encephalopathy is a decline in brain function that occurs when the liver is unable to remove toxins from the blood. This condition can manifest in various ways, including confusion, lethargy, and in severe cases, coma.
In your father's case, the presence of cirrhosis and the recent diagnosis of hepatocellular carcinoma (HCC) complicate his condition. The symptoms you describe, such as slowness of movement and increased fatigue, are indeed consistent with HE. The management of HE typically involves addressing the underlying liver dysfunction and reducing the levels of ammonia in the blood, which is a primary contributor to the symptoms of HE.
The standard treatment for HE includes the use of lactulose, a non-absorbable disaccharide that helps to lower ammonia levels by promoting its excretion through the intestines. It is important to adhere to the prescribed dosage of lactulose, as excessive intake can lead to diarrhea and electrolyte imbalances. While it may be tempting to increase the dosage on your own, it is crucial to consult with your healthcare provider before making any changes to the medication regimen. They can provide guidance on the appropriate dosage based on your father's specific condition and response to treatment.
In addition to lactulose, other treatments may include the use of rifaximin, an antibiotic that can help reduce the production of ammonia by altering gut flora. In some cases, patients may require more aggressive interventions, such as intravenous fluids or even hospitalization, especially if they exhibit severe symptoms or if ammonia levels are critically high. If your father experiences significant changes in his mental status or worsening symptoms, it is advisable to seek emergency medical care for evaluation and potential treatment.
Regarding the new symptom of facial twitching or tremors, this could be related to hepatic encephalopathy or other neurological issues associated with liver disease. Muscle twitching can occur due to a variety of reasons, including electrolyte imbalances, neurological effects of liver dysfunction, or even medication side effects. It is essential to discuss this new symptom with your father's healthcare provider, as they may want to conduct further assessments to determine the underlying cause and appropriate management.
Regular follow-up appointments are crucial for monitoring liver function and managing complications associated with cirrhosis and HE. Blood tests, including ammonia levels, liver function tests, and possibly imaging studies, can help assess the progression of liver disease and the effectiveness of treatment strategies.
In summary, managing hepatic encephalopathy in cirrhosis patients involves a combination of medication, monitoring, and supportive care. It is vital to maintain open communication with your father's healthcare team, adhere to prescribed treatments, and seek medical attention for any new or worsening symptoms. This proactive approach can help improve your father's quality of life and potentially mitigate the complications associated with his liver disease.
