Acute Liver Failure Or Fulminant Hepatic Failure | Sign Symtoms | Causes | Risk Factors | Treatment Acute liver failure is loss of liver function that occurs rapidly — in days or weeks —usually in a person who has no pre-existing Liver disease. Acute liver failure is less common than chronic liver failure, which develops more slowly. Acute liver failure, also known as fulminant hepatic failure, can cause serious complications, including excessive bleeding and increasing pressure in the brain. It's a medical emergency that requires hospitalization. Depending on the cause, Acute liver failure can sometimes be reversed with treatment. In many situations, though, a liver transplant may be the only cure. SYMPTOMS Signs and symptoms of Acute liver failure may include: Yellowing of your skin and eyeballs (jaundice) Pain in your upper right abdomen Abdominal swelling Nausea Vomiting A general sense of feeling unwell (malaise) Disorientation or confusion Sleepiness CAUSES Acute liver failure occurs when liver cells are damaged significantly and are no longer able to function. Potential causes include: Acetaminophen overdose. Taking too much acetaminophen (Tylenol, others) is the most common cause of Acute liver failure in the United States. Acute liver failure can occur after one very large dose of acetaminophen, or after higher than recommended doses every day for several days. If you suspect that you or someone you know has taken an overdose of acetaminophen, seek medical attention as quickly as possible. Do not wait for the signs of liver failure. Prescription medications. Some prescription medications, including antibiotics, nonsteroidal anti-inflammatory drugs and anticonvulsants, can cause Acute liver failure. Herbal supplements. Herbal drugs and supplements, including kava, ephedra, skullcap and pennyroyal, have been linked to Acute liver failure. Hepatitis And other viruses. Hepatitis A, Hepatitis B and Hepatitis E can cause Acute liver failure. Other viruses that can cause Acute liver failure include Epstein-Barr virus, cytomegalovirus and herpes simplex virus. Toxins. Toxins that can cause Acute liver failure include the poisonous wild mushroom Amanita phalloides, which is sometimes mistaken for edible species. Autoimmune disease. Liver failure can be caused by Autoimmune hepatitis — a disease in which your immune system attacks liver cells, causing inflammation and injury. Diseases of the veins in the liver. Vascular diseases, such as Budd-Chiari syndrome, can cause blockages in the veins of the liver, leading to Acute liver failure. Metabolic disease. Rare metabolic diseases, such as Wilson's disease and acute fatty liver of pregnancy, infrequently cause Acute liver failure. Cancer. Cancer that either begins in or spreads to your liver can cause your liver to fail. Many cases of Acute liver failure have no apparent cause. COMPLICATIONS Acute liver failure often causes complications, including: Excessive Fluid in the brain (cerebral Edema). Excessive Fluid causes pressure to build in your brain, which can displace brain tissue outside of the space it normally occupies (Herniation). Cerebral Edema can also deprive your brain of oxygen. Bleeding and bleeding disorders. A failing liver isn't able to produce sufficient amounts of clotting factors, which help blood to clot. People with Acute liver failure often develop bleeding from the gastrointestinal tract. Bleeding may be difficult to control. Infections. People with Acute liver failure are at an increased risk of developing a variety of infections, particularly in the blood and in the respiratory and urinary tracts. Kidney failure. Kidney failure often occurs following liver failure, especially in cases of acetaminophen overdose, which damages both your liver and your kidneys TESTS AND DIAGNOSIS Tests and procedures used to diagnose Acute liver failure include: Blood tests. Blood tests to determine how well your liver is functioning may include the prothrombin time test, which measures how long it takes your blood to clot. With Acute liver failure, blood won't clot as quickly as it should. Imaging tests. Your doctor may recommend imaging tests, such as ultrasound, to evaluate your liver. Imaging tests may show liver damage and may help your doctor determine the cause of your liver problems. Examination of liver tissue. Your doctor may recommend a procedure to remove a small piece of liver tissue (liver biopsy). Tests of the liver tissue may help your doctor understand why your liver is failing TREATMENTS AND DRUGS Treatments for Acute liver failure Acute liver failure treatments may include: Medications to reverse poisoning. Acute liver failure caused by acetaminophen overdose or mushroom poisoning is treated with drugs that can reverse the effects of the toxin and may reduce liver damage. Liver transplant. When Acute liver failure can't be reversed, the only treatment may be a liver transplant.
