Oxidative And Nitrosative Stress

Enhanced production of reactive nitrogen species and reactive oxygen species occurs in cultured astrocytes that are exposed to ammonia, inflammatory cytokines, hyponatremia or benzodiazepines. Its suggested that glutamine formed in the cytoplasm enters the mitochondrial matrix and is cleaved to release ammonia while still inside the mitochondria. Evidence indicating a close association and interplay between astrocyte swelling and ROS is now growing.

How To Recognize The Symptoms Of He

If you have liver disease, it is important to know the symptoms of HE. By paying close attention to your mental and physical symptoms, you can alert your doctor before things get worse.

HE can be either covert or overt depending on the degree of the symptoms:

  • Covert HE symptoms can go unnoticed, even by a doctor
  • Overt HE symptoms are more noticeable to other people

Symptoms of overt HE can include:

What Is Cryptogenic Cirrhosis?

How long Xifaxan takes to work will depend on the condition you are treating. For travelers diarrhea, most people begin to feel better by day two of treatment, but you should still finish your complete treatment. Two weeks of treatment is often needed for IBS-D treatment. Preventing hepatic encephalopathy requires long-term treatment.

Why Do We Use Lactulose And Rifaximin For Hepatic Encephalopathy

Lactulose and Rifaximin are standards of care for the prevention of overt hepatic encephalopathy in patients with cirrhosis.

Have you ever wondered why? Join us!

First, if you want a refresher on hepatic encephalopathy , check out our Quick Tips post by Lizzie Aby.

What is the first step in treating HE?

Reverse the underlying cause!!!

Infections, GI bleeding, medications, and dehydration can precipitate HE and treating these factors is most important in reversing an acute episode of HE.

So what next?

Medical therapy!

Lactulose, a non-absorbable sugar composed of galactose and glucose was first made in 1929. It was first used in 1966 by Bircher et al. to treat HE:

In this case report, the authors describe the proposed mechanism of action for the drug:

The non-absorbed lactulose passes intact into the ascending colon, where it is split by bacterial action into lower molecular organic acids . Their osmotic effect creates a fermentive diarrhea identical to the lactose-induced diarrhea in lactase-deficient subjects. The lowered fecal pH caused by the presence of these organic acids should hypothetically entail a change in colonic bacterial flora or a change in bacterial metabolism. An increase in fermentation and a decrease in putrefaction is to be expected this should decrease the amount of nitrogenous compounds which are toxic in the portal-systemic encephalopathy.

So doc, what else can I use for an acute episode of HE?

Here comes RIFAXIMIN!!!!

How Should I Take Xifaxan

Take Xifaxan exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

You may take this medicine with or without food.

For travelers’ diarrhea, Xifaxan is usually taken for only 3 days. For IBS, it is usually taken for 2 weeks at a time. Follow your doctor’s dosing instructions very carefully.

Use this medicine for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. Xifaxan will not treat a viral infection such as the flu or a common cold.

Do not share this medicine with another person, even if they have the same symptoms you have.

Xifaxan does not treat all bacterial forms of travelers’ diarrhea.

Store at room temperature away from moisture and heat.

Medication Compliance

In order to get maximum benefit from your medications, its important to take them as prescribed meaning taking the right dose, the right way, at the right time, for as long as necessary. With proper adherence to therapy, the progression of HE can be slowed and sometimes even stopped.

Adhering to other aspects of your treatment plan is also important. Communicating with members of your healthcare team, keeping your medical appointments, getting the necessary lab tests, and eating an appropriate diet will help to maximize your chance of treatment success and minimize potential problems.

Ammonia Hypothesis

For sodium benzoate to be effective, renal clearance of hippurate is required. For patients with end-stage renal disease, some benzoate and hippurate will be removed by dialysis. Studies evaluating the effect of dialysis on clearance of sodium benzoate are limited. However, a case study involving an infant found that sodium benzoate is removed fairly efficiently by dialysis .19 Despite the efficiency of clearance of sodium benzoate by dialysis, sodium benzoate was still effective in lowering serum ammonia levels.

Overt He Happens When Your Liver Cannot Filter Toxins In Your Blood And The Toxins Build Up And Reach Your Brain

The liver is important because it filters your blood, including everything that you eat and drink, such as food, alcohol, and medicines. It helps process food into energy and nutrients that your body can use. It also gets rid of toxins in your blood, which otherwise may be harmful to your body.

When your liver is damaged, it cannot remove toxins as well as a healthy liver can. When toxins build up in your brain, you may have short-term and long-term effects that can get worse over time.

Rifaximin Versus Nonabsorbable Disaccharides For The Treatment Of Hepatic Encephalopathy: A Meta

AST SGOT Levels: Understanding the Result

Ling XuChuan-Yong GuoAcademic Editor: Received


Background. Many studies have found that the antibiotic rifaximin is effective for the treatment of hepatic encephalopathy. However, there is no uniform view on the efficacy and safety of rifaximin. Methods. We performed a meta-analysis through electronic searches to evaluate the efficacy and safety of rifaximin in comparison with nonabsorbable disaccharides. Results. A total of 8 randomized controlled trials including 407 patients were included. The efficacy of rifaximin was equivalent to nonabsorbable disaccharides according to the statistical data : 1.06, 95% CI: 0.941.19 ). Analysis showed that patients treated with rifaximin had better results in serum ammonia levels : 10.63, 95% CI: 30.639.38 ), mental status , asterixis , electroencephalogram response , and grades of portosystemic encephalopathy , but only the last ones had statistical significance. The safety of rifaximin was better than nonabsorbable disaccharides . . Rifaximin is at least as effective as nonabsorbable disaccharides, maybe better for the treatment of hepatic encephalopathy. And the safety of rifaximin is better.

How Should This Medicine Be Used

Rifaximin comes as a tablet to take by mouth with or without food. When rifaximin is used to treat traveler’s diarrhea, it is usually taken three times a day for 3 days. When rifaximin is used to prevent episodes of hepatic encephalopathy, it is usually taken twice a day. When rifaximin is used to treat irritable bowel syndrome, it is usually taken three times a day for 14 days. To help you remember to take rifaximin, take it around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take rifaximin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you are taking rifaximin to treat traveler’s diarrhea, your symptoms should improve within 24 to 48 hours after you start taking the medication. If your symptoms do not go away or they get worse, or if you develop a fever or bloody diarrhea, call your doctor.

If you are taking rifamaxin to treat irritable bowel syndrome and your symptoms return after you have finished your treatment, call your doctor.

Xifaxan: Hepatic Encephalopathy Prevention

Xifaxan is sometimes used to prevent hepatic encephalopathy . This condition is related to a late-stage liver disease known as liver cirrhosis. This is Stage 3 of liver disease and involves major tissue scarring that affects liver function.

HE causes various symptoms. They include reduced brain function that causes symptoms like lack of focus and confusion. It can also affect physical movement and even result in comas. Health experts believe that gut toxins are closely linked to HE symptoms.

The treatment strategies for HE focus on reducing ammonia and other gut toxins. Theres also a focus on treating conditions that trigger HE symptoms. The standard treatment for HE is a medicine thats believed to reduce the bodys ammonia absorption.

Xifaxan is an antibiotic thats slightly absorbed. Its believed it might reduce the bodys ammonia production. Thats by reducing ammonia-making bacteria. Several small studies show that the antibiotic is effective in treating HE.

The body also seems to tolerate the drug effectively. Various studies have been done to test the effectiveness of the antibiotic in preventing HE from returning. In one study the Xifaxan had a nearly 60% drop in HE. There was also a 50% drop in HE-related hospitalizations within 6 months. In fact, the side-effects were also similar to the fake pills.

Assessment Of The Need For Long

Patients with cirrhosis are at risk of developing new episodes of encephalopathy. Several factors need to be considered:

Diet and Nutrition

Low-protein diets are often erroneously recommended for patients with cirrhosis, in hopes of decreasing intestinal ammonia production and of preventing exacerbations of HE. An obvious consequence was the worsening of preexisting protein-energy malnutrition. Protein restriction may be appropriate in some patients immediately following a severe flare of symptoms . However, protein restriction is rarely justified in patients with cirrhosis and persistent HE. Indeed, malnutrition is a more serious clinical problem than HE for many of these patients.

It is the infrequent patient who is intolerant of a diet high in protein. Most patients with mild chronic HE tolerate more than 60 to 80 g of protein per day.

Diets containing vegetable proteins appear to be better tolerated than diets rich in animal protein. This may be because of increased content of dietary fiber, a natural cathartic, and decreased levels of AAA. AAA, as precursors for the false neurotransmitters tyramine and octopamine, are thought to inhibit dopaminergic neurotransmission and worsen HE. Ingestion of red meat protein should be discouraged.

    Inclusion And Exclusion Criteria

    According to PICOS criteria, two reviewers independently selected and evaluated the studies through different databases. The studies were included if they met the following criteria: : Participant: adults with an age of at least 18 years Intervention: assessment of the efficacy and safety of rifaximin on patients with liver cirrhosis and overt, minimal, or recurrent HE Comparator: rifaximin compared with other interventions, such as placebo and other active drugs Outcomes: primary outcomes, including OHE improvement, MHE reversal, prevention of recurrent HE, mortality, and adverse effects secondary outcomes, including blood ammonia level, mental state, flapping tremor, rehospitalization, and portosystemic encephalopathy index Study design: RCTs with either multicentre or single-centre design. Exclusion criteria were: : trials conducted among children patients non-controlled clinical trials and phase I clinical trials trials that assessed the efficacy and safety of rifaximin combined with other active drugs trials including patients with psychiatric illness, with undercurrent infections, with hypersensitivity to rifaximin or intolerance to other active drugs.

    Search For A Clinical Trial

    Clinical trials are research studies that test how well new medical approaches work in people. Before an experimental treatment can be tested on human subjects in a clinical trial, it must have shown benefit in laboratory testing or animal research studies. The most promising treatments are then moved into clinical trials, with the goal of identifying new ways to safely and effectively prevent, screen for, diagnose, or treat a disease.

    Speak with your doctor about the ongoing progress and results of these trials to get the most up-to-date information on new treatments. Participating in a clinical trial is a great way to contribute to curing, preventing and treating liver disease and its complications

    What Is Xifaxan Used For

    The Food and Drug Administration approved Xifaxan to treat several conditions, including:

    • Travelers diarrhea: Xifaxan treats travelers diarrhea caused by certain bacteria in adults and children aged 12 years and older. Xifaxan should not be used to treat diarrhea if you have blood in your stool or a fever. Travelers diarrhea describes symptoms that occur within 10 days of traveling to an area with poor public hygiene. Consuming water or food contaminated with bacteria can cause this condition. Traveling to developing countries in Asia, Africa, Central America and South America, and the Middle East often poses the greatest risk.
    • Irritable bowel syndrome with diarrhea : Rifaxamin is prescribed for people with IBS-D, often when other treatments have failed. Several studies have shown a two-week trial of Xifaxan significantly improves diarrhea and bloating symptoms.
    • To prevent HE in adults with liver disease:People with liver disease have trouble removing naturally occurring toxins from their bodies. When these toxins build up, they can travel to the brain and cause symptoms, including confusion, slurred speech, and reduced alertness.
