What is hepatic encephalopathy
Hepatic encephalopathy (HE) is a neuropsychiatric syndrome caused by severe damage to liver function or portosystemic shunting, which mainly manifests as cognitive dysfunction, behavioral abnormalities and disturbance of consciousness. It is a common complication of liver diseases such as cirrhosis and acute liver failure, and can be life-threatening in severe cases. In recent years, the pathogenesis, diagnosis and treatment of hepatic encephalopathy have become hot topics in the medical community.
1. Pathogenesis of hepatic encephalopathy
The pathogenesis of hepatic encephalopathy is complex and is currently believed to be mainly related to the following factors:
| mechanism | illustrate |
|---|---|
| Ammonia poisoning | The liver cannot metabolize ammonia normally, causing blood ammonia to rise and affecting brain function. |
| inflammatory response | Gut bacterial translocation triggers systemic inflammation and worsens brain damage |
| neurotransmitter imbalance | Increased GABAergic neurotransmitters, depressing the central nervous system |
| oxidative stress | Free radical accumulation causes neuronal damage |
2. Clinical manifestations of hepatic encephalopathy
The symptoms of hepatic encephalopathy can be divided into different stages from mild to severe. The specific manifestations are as follows:
| installment | clinical manifestations |
|---|---|
| Issue 0 | No obvious symptoms, only psychological tests can detect abnormalities |
| Issue 1 | Mild cognitive impairment, difficulty concentrating, sleep disturbance |
| Issue 2 | Drowsiness, abnormal behavior, disorientation |
| Issue 3 | Drowsy but arousable, obviously confused |
| Issue 4 | Coma, unresponsive to pain |
3. Diagnostic methods of hepatic encephalopathy
The diagnosis of hepatic encephalopathy requires a combination of clinical manifestations and laboratory tests:
| Check items | significance |
|---|---|
| Blood ammonia test | Elevated blood ammonia is an important indicator, but it is not absolute |
| liver function test | Assessment of liver anabolic and metabolic function |
| electroencephalogram | Displays characteristic three-phase waves |
| psychological test | Digital connectivity tests and more can detect early lesions |
| Imaging examination | Rule out other central nervous system diseases |
4. Treatment strategies for hepatic encephalopathy
The treatment of hepatic encephalopathy mainly includes etiological treatment and symptomatic treatment:
| Treatment | Specific measures |
|---|---|
| Eliminate triggers | Control infection, correct electrolyte imbalance, stop bleeding, etc. |
| Reduce ammonia production | Limit protein intake, use lactulose, rifaximin, etc. |
| Promote ammonia metabolism | Supplement with branched chain amino acids, use ornithine aspartate |
| liver transplant | Fundamental treatments for end-stage liver disease |
5. Preventive measures for hepatic encephalopathy
The key to preventing hepatic encephalopathy lies in managing underlying liver disease and avoiding triggers:
1.Diet management:Eat an appropriate amount of protein and avoid high-protein diets; ensure adequate calories; limit sodium intake.
2.Regular follow-up visits:Monitor liver function, blood ammonia and other indicators regularly.
3.Avoid triggers:Prevent infection, avoid constipation, use sedatives with caution, etc.
4.Health education:Improve patients’ and family members’ understanding of the disease and early identification of symptoms.
6. Recent research hotspots
1.Microbiome Research:The relationship between intestinal flora and hepatic encephalopathy has become a research hotspot, and probiotic regulation may become a new therapy.
2.New diagnostic markers:Search for more sensitive and specific biomarkers for early diagnosis.
3.Targeted therapy:Develop specific drugs for different pathogenesis.
4.Artificial Intelligence Applications:Use AI technology to assist in the early identification and prognosis assessment of hepatic encephalopathy.
Hepatic encephalopathy is a preventable and treatable disease, and early identification and intervention are crucial to improving prognosis. With the deepening of medical research, the level of diagnosis and treatment of hepatic encephalopathy will continue to improve, bringing more hope to patients.
