How To Cure Hepatic Encephalopathy

Diagnosing And Treating Hepatic Encephalopathy

Refining the Ammonia Hypothesis to Treat Hepatic Encephalopathy

To properly diagnose hepatic encephalopathy, your doctor will need a complete blood count. A low red blood count can indicate a lack of oxygen. Your doctor may also measure levels of potassium, ammonia, and sodium, as high levels of these indicate impaired liver function.

Other diagnostic tests include imaging tests like CT scans or MRI to check for bleeding in the brain as well as liver function tests. Raised liver enzyme levels can indicate added stress or damage to the liver.

Treatment for hepatic encephalopathy depends on the severity and the underlying cause. For starters, you will be advised to consume less protein in your diet. Your doctor will help you adhere to a diet that reduces protein but ensures you still get adequate amounts to function properly. High protein foods to avoid include poultry, red meat, eggs, and fish.

Your doctor will also prescribe medications to help slow down the rate of absorption of toxins by the blood.

In severe cases, you may require a ventilator if a patient has difficulties breathing.

Nitric Oxide & The Brain

Nitric oxide is a highly reactive free radical. It is produced by a group of enzymes called nitric oxide synthases . Under normal conditions, NO behaves as a neurotransmitter and antimicrobial substance.

When the brain is in a chronic inflammatory state, overstimulated astrocyte immune system cells release lots of NOS. The high levels of NO they produce are extremely toxic to neurons. Studies show that curcumin can suppress dangerous levels of NOS and NO free radicals.

What Is Hepatic Encephalopathy In Dogs

Hepatic encephalopathy is a degenerative brain disease that is caused by a buildup of ammonia in the body.

Since a healthy liver in dogs helps to filter the blood and rid the body of excess toxins such as ammonia, a damaged liver struggles to get the job done.

Because of this, ammonia will begin to build up in the blood, eventually affecting the central nervous system.

Once the central nervous system is impacted by this excess amount of ammonia in the body, the concerning symptoms of hepatic encephalopathy begin to develop.

Clinical Scales For Grading He

Management of Hepatic Encephalopathy in 5 Minutes

A number of scales have been devised for the diagnosis of HE the first of its kind was proposed by Parsonsmith and colleagues in 1957. For patients with moderate to severe HE, the Glasgow Coma scale can also be employed.

Table 1: West-Haven Criteria for Hepatic Encephalopathy

Normal examination if impaired psychomotor testing, consider MHE
1 Impaired addition or subtraction mild asterixis or tremor

MHE, minimal hepatic encephalopathy.

The West-Haven Classification Table

Stage 0. MHE . Lack of detectable changes in personality or behavior. Minimal changes in memory, concentration, intellectual function, and coordination. Asterixis is absent.

Stage 1. Trivial lack of awareness. Shortened attention span. Impaired addition or subtraction. Hypersomnia, insomnia, or inversion of sleep pattern. Euphoria, depression, or irritability. Mild confusion. Slowing of ability to perform mental tasks. Asterixis can be detected.

Stage 2. Lethargy or apathy. Minimal disorientation. Inappropriate behavior. Slurred speech. Obvious asterixis. Drowsiness, lethargy, gross deficits in ability to perform mental tasks, obvious personality changes, inappropriate behavior, and intermittent disorientation, usually regarding time.

Stage 3. Somnolent but can be aroused, unable to perform mental tasks, gross disorientation about time and place, marked confusion, amnesia, occasional fits of rage, present but incomprehensible speech.

Treatments To Increase Ammonia Clearance

Zinc. Low zinc concentrations are common in patients with cirrhosis of the liver, particularly those with HE. Even in patients who are not zinc deficient. Patients with fulminant hepatic failure and subacute hepatic failure have also been shown to have low serum zinc levels. Zinc deficiency also leads to alteration of neurotransmitters like GABA and norepinephrine. Zinc supplementation has been tried in HE. It may have a role in mild chronic HE, though further trials are necessary.

Unequivocal evidence of benefit of oral zinc therapy for treatment of acute HE is lacking. Zinc sulfate and zinc acetate have been used at a dose of 600 mg orally every day in clinical trials. HE improved in two studies there was no improvement in mental function in two other studies. However, an interesting study from Japan in 2010 showed zinc supplementation significantly improved patients’ quality of life, as it improved the physical component scale but not the mental component scale. Zinc supplementation also significantly decreased HE grade and blood ammonia levels and improved Child-Pugh score and neuropsychological tests compared with standard therapy. Interestingly this study showed as well administration of zinc in combination with L-carnosine showed to enhance intestinal barrier and improve zinc plasma levels.

Differential Diagnosis For Hepatic Encephalopathy

Distinguishing hepatic encephalopathy from other acute and chronic causes of altered mental status may be difficult in patients with cirrhosis. A decision to perform additional neurologic studies should be based on the severity of the patient’s mental dysfunction, the presence of focal neurologic findings , and the patient’s responsiveness to an empiric trial with cathartic agents. Even patients with severe hepatic encephalopathy should demonstrate steady improvement in mental dysfunction after initiation of treatment with lactulose.

Differential diagnoses of encephalopathy are as follows :

  • Intracranial lesions, such as subdural hematoma, intracranial bleeding, stroke, tumor, and abscess

  • Infections, such as meningitis, encephalitis, and intracranial abscess

  • Metabolic encephalopathy, such as hypoglycemia, electrolyte imbalance, anoxia, hypercarbia, and uremia

  • Hyperammonemia from other causes, such as ureterosigmoidostomy and inherited urea cycle disorders

  • Toxic encephalopathy from alcohol intake, such as acute intoxication, alcohol withdrawal, and Wernicke encephalopathy

  • Toxic encephalopathy from drugs, such as sedative hypnotics, antidepressants, antipsychotic agents, and salicylates

  • Organic brain syndrome

    Risks And Symptoms Of Hepatic Encephalopathy

    Hepatic Encephalopathy

    The livers main role is to filter out toxins from the body. These toxins could be introduced by environmental factors, diet, and even the medications we take. When the liver is healthy, it can filter our these toxins without problems. But a sick and damaged liver cannot complete this function, which results in a toxin buildup.

    What Are The Symptoms Of Hepatic Encephalopathy

    The symptoms of hepatic encephalopathy are part of what makes this condition so scary for pet owners.

    This degenerative condition can bring with it a number of alarming symptoms, all of which cause great concern among dog owners.

    The most common symptoms of hepatic encephalopathy in dogs include:

    • Disorientation
    • Seizures

    Diagnosis And Testing For Overt He

    The diagnosis of overt HE is based on a clinical examination and a clinical decision. Clinical scales are used to analyse its severity. Specific quantitative tests are only needed in study settings. The gold standard is the West-Haven criteria . The detection of disorientation and asterixis has good inter-rater reliability, and thus are chosen as marker symptoms of overt HE . Orientation or mixed scales have been used to distinguish the severity of HE . In patients with evidently altered consciousness, the Glasgow Coma Scale is widely employed. Diagnosing cognitive dysfunction by clinical observation, neuropsychological or neurophysiological tests is not difficult. The difficulty is to assign them to HE. For this reason, overt HE still remains a diagnosis of exclusion in this patient population that is often susceptible to mental status abnormalities due to medications, alcohol abuse, drug use, effects of hyponatremia and psychiatric disease. Therefore, as clinically indicated, exclusion of other etiologies by laboratory and radiological assessment for a patient with altered mental status in HE is warranted.

    Is Lactulose An Effective Therapy

    Using lactulose for hepatic encephalopathy is a very effective therapy. But remember that it does not in any way cure H.E. It only helps to manage the symptoms, especially when it comes to your mental status. However, ensure to follow all of your doctors directions and carry him or her along with how you feel as you use the medication.

    Diagnosis Of Hepatic Encephalopathy In Dogs

    Figure 1 from Current Management of Hepatic Encephalopathy ...

    Not all liver problems are related to hepatic encephalopathy. Your veterinarian may recommend tests that rule out other diseases. The veterinary specialist will require pertinent information such as symptoms your pet typically displays at home, his daily dietary schedule and what type of food he eats, his urinary habits, and which, if any, supplements or vitamins you may be giving your pet. Laboratory tests may include:

    • Blood ammonia
    • Urinalysis
    • X-rays and ultrasound of the abdomen

    If further investigation is needed, a liver biopsy could be suggested. The veterinarian will want to determine at what stage of hepatic encephalopathy your pet has reached as the treatment will vary accordingly.

    Reversibility Of Hepatic Encephalopathy

    Classically, hepatic encephalopathy was regarded as a reversible condition. Patients appeared to improve with either drug therapy or liver transplantation. However, a recent study assessed cirrhotic patients who had apparently recovered from an episode of overt hepatic encephalopathy. After careful psychometric testing, it was discovered that these clinically improved patients had residual cognitive impairment compared with cirrhotic patients with either minimal hepatic encephalopathy or no encephalopathy.

    In 2009, Sotil et al evaluated 39 patients who had undergone liver transplantation about 1.5 years before the study. The 25 patients who had hepatic encephalopathy prior to transplantation, on the whole, performed worse on psychometric testing than the 14 patients with no history of overt encephalopathy prior to transplantation.

    In 2011, Garcia-Martinez et al assessed the cognitive function in 52 patients who had undergone liver transplantation. Global cognitive function after transplantation was worse in patients with a history of alcohol-induced cirrhosis, patients with diabetes, and patients with a history of hepatic encephalopathy prior to transplantation. Furthermore, the brain volume after transplantation was smaller in patients with a history of hepatic encephalopathy prior to transplantation than in patients with no overt encephalopathy. These are provocative findings that require additional investigation.

    Recovery Of Hepatic Encephalopathy In Dogs

    Canines who have been treated for hepatic encephalopathy will need continued care once home. The veterinarian will give specific instructions based on your pets case and the cause for the condition. A dietary recommendation will be prescribed and must be followed in order to prevent a recurrence of the neurological signs that your pet may have experienced. Often, probiotic yogurt is part of the dietary change, as is a protein modified diet. Studies show that a feeding regimen with a monitored protein allowance has given pets with liver disease quality of life after diagnosis yogurt, cheddar cheese, and cottage cheese are often the recommended choices.

    A canine who has undergone surgery will have exercise restrictions and will need a quiet restful corner in which to convalesce. Monitor your pet for several days after he returns home from the clinic and adhere to the instructions provided by the veterinary team, continuing the course of all medications even if your pet seems to be feeling fine.

    Life Expectancy In Dogs With Hepatic Encephalopathy

    Liver Transplant for Severe Hepatic Encephalopathy

    When a dog with hepatic encephalopathy receives treatment from the moment their symptoms begin, their prognosis is generally good.

    Though they have often suffered irreversible liver damage in many cases, their HE can be managed with proper medical care.

    As long as the dog owner is dedicated to following the veterinarians instructions, offering their daily medications religiously, and keeping up with follow up diagnostics these dogs have the ability to live full lives.

    Because of this, their life expectancy can be anywhere from 6 months to 2 years.

    Just be sure to keep a close eye on your dog, and notify your vet of any decline in their health throughout the process.

    Hepatic encephalopathy in dogs is a serious condition that can cause our dog great distress.

    Be sure to review the information we discussed above, and you will better understand this disease going forward.

    Testing For Minimal And Covert He

    Minimal and covert HE is defined as the presence of test-dependent or clinical signs of brain dysfunction in patients with chronic liver disease who are not disoriented or display asterixis. The term minimal conveys that there is no clinical sign, cognitive or other, of HE. The term covert includes minimal and Grade 1 HE. The testing strategies can be divided into two major types: psychometric and neurophysiological . Since the condition affects several components of cognitive functioning, which may not be impaired to the same degree, the ISHEN suggests the use of at least two tests depending on the local population norms and availability, and preferably with one of the tests being more widely accepted so as to serve as a comparator.

    The most established testing strategies are:

  • Portosystemic encephalopathy SyndromeTest consists of five paperpencil tests that evaluate cognitive and psychomotor processing speed and visuomotor coordination. The tests are relatively easy to administer and have good external validity . It can be obtained from Hannover Medical School that holds the copyright .

  • The Critical Flicker Frequency test is a psycho-physiological tool, which is defined as the frequency at which a fused light appears to be flickering to the observer. Studies have shown its reduction with worsening cognition and improvement after therapy. It requires several trials, intact binocular vision, absence of red-green blindness and specialized equipment .

  • Ventilator Or Oxygen Mask

    Hepatic encephalopathy can cause many mental and physical changes, and even after taking all precautions, there is a possibility for the illness to progress. If it creates difficulty in breathing, a ventilator or oxygen mask may be needed to support the patient until toxins can be removed from the body. Without assistance with breathing, a patient could suffer catastrophic events and need additional medical support.

    A ventilator is a machine hooked up to a tube that goes down the throat into the lungs. This means the machine is breathing for the patient. The oxygen mask is less intrusive and covers both the nose and mouth and has oxygen pumped through it. It can help force more oxygen down the throat of the patient to aid in breathing. As the hepatic encephalopathy starts being controlled through different interventions, the patient may be able to come off the ventilator or no longer need the oxygen mask.

    Popular Hepatic Encephalopathy Drugs

    Note: Popularity is based on total prescriptions for the brand and generic versions of each drug, regardless of the condition being treated. Some drugs are prescribed for multiple conditions.

    Osmotic laxatives are used for colon cleanses and to treat constipation and hepatic encephalopathy. They work by absorbing water into the stool making bowel movements more frequent to remove toxic substances.

    Aminoglycoside antibiotics are used to treat eye infections, conjunctivitis, cystic fibrosis, bacterial infections, hepatic encephalopathy, and skin infections. They work by eliminating and preventing the multiplying of the bacteria that causes the infection.

    Rifamycins are used to treat tuberculosis, skin infections, hepatic encephalopathy, diarrhea, and irritable bowel syndrome. They work by killing the bacteria causing the infections.

    What Are The Stages Of He

    • Stage 1: Mild HE

    Patients may have sleep problems and trouble concentrating. Mood swings may also be noticed.

    • Stage 2: Moderate HE

    Patients may feel a lack of energy. They may keep forgetting things. Strange behavioral changes are seen and slur speech may be observed. Their hands might shake, and they may face difficulty in writing, as well as doing simple mathematical calculations.

    • Stage 3: Severe HE

    At this stage patients usually feel very lethargic and sleepy. Thinking and reasoning ability may be drastically affected and they cant do basic maths at all. Obvious changes in behaviour are seen. Patients may become anxious.

    • Stage 4: Coma

    The final stage is comathe patient is unconscious and cannot be awakened fails to respond normally to pain, light, or sound lacks a normal wake-sleep cycle and does not initiate voluntary movements

    If the patient has already been diagnosed with HE and you feel that the condition is worsening then contact the doctor immediately.
