What to know about nonalcoholic fatty liver disease Nonalcoholic fatty liver disease is a condition in which fatty deposits build up in the liver. What to know about liver disease symptoms.

The most common causes of pancreatitis are gallstones and alcohol use. Gallstones are responsible for more than one half of cases of acute pancreatitis, which is caused by obstruction of the common duct that drains the biliary and pancreatic systems.

The physical examination should focus primarily on signs of liver disease other than jaundice, including bruising, spider angiomas, gynecomastia, testicular atrophy, and palmar erythema. An abdominal examination to assess liver size and tenderness is important. The presence or absence of ascites also should be noted. The initial work-up of the patient with jaundice depends on whether the hyperbilirubinemia is conjugated direct or unconjugated indirect. A urinalysis that is positive for bilirubin indicates the presence of conjugated bilirubinemia.

Conjugated bilirubin is water soluble and therefore able to be excreted in urine. The findings of urinalysis should be confirmed by measurements of the serum total and direct bilirubin levels Figure 1. A CBC is useful in detecting hemolysis, which is indicated by the presence of fractured red blood cells schistocytes and increased reticulocytes on the smear.

They can be less helpful in patients with chronic liver disease, because levels can be normal or only slightly elevated when there is little liver parenchyma left to damage. Acute viral hepatitis may cause the levels of ALT to rise several thousand units per liter. Levels greater than 10, U per L usually occur in patients with acute injury to the liver from another source e. As bile obstruction progresses, the levels of these two markers rise several times above normal.

Depending on the results of the initial tests, further serum tests or imaging studies may be warranted.

The second-line serum investigations may include tests for hepatitis A IgM antibody, hepatitis B surface antigen and core antibody, hepatitis C antibody, and autoimmune markers such as antinuclear, smooth muscle, and liver-kidney microsomal antibodies. An elevated amylase level would corroborate the presence of pancreatitis when this condition is suspected based on the history or physical examination.

Algorithm for a systematic approach to the adult patient with jaundice. Ultrasonography and computed tomographic CT scanning are useful in distinguishing an obstructing lesion from hepatocellular disease in the evaluation of a jaundiced patient. Ultrasonography is typically the first test ordered, because of its lower cost, wide availability, and lack of radiation exposure, which may be particularly important in pregnant patients. While ultrasonography is the most sensitive imaging technique for detecting biliary stones, CT scanning can provide more information about liver and pancreatic parenchymal disease.

Neither modality is good at delineating intraductal stones. Further imaging that may be done by a gastroenterologist or interventional radiologist includes endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography. A liver biopsy provides information on the architecture of the liver and is used mostly for determining prognosis. It also may be useful for diagnosis if serum and imaging studies do not lead to a firm diagnosis.

Liver biopsy can be particularly helpful in diagnosing autoimmune hepatitis or biliary tract disorders e. Patients with primary biliary cirrhosis are almost always positive for antimitochondrial antibody, and the majority of those affected by primary sclerosing cholangitis have antineutrophil cytoplasmic antibodies. The risk of fatal hemorrhage in patients undergoing percutaneous liver biopsy is 0. Already a member or subscriber? Log in. Interested in AAFP membership? Learn more.

What Causes High Bilirubin? Medically reviewed by Karen Gill, M. Symptoms Causes Warning signs Takeaway What is bilirubin? What are the symptoms of high bilirubin?

What causes high bilirubin? Should I be concerned? The bottom line. Mild jaundice is best seen by examining the sclerae in natural light; it is usually detectable when serum bilirubin reaches 2 to 2. Breath odor should be noted eg, for fetor hepaticus. The abdomen is inspected for collateral vasculature, ascites Ascites Ascites is free fluid in the peritoneal cavity.

The most common cause is portal hypertension. Symptoms usually result from abdominal distention. Diagnosis is based on physical examination and The liver is palpated for hepatomegaly, masses, nodularity, and tenderness. The spleen is palpated for splenomegaly.

The abdomen is examined for umbilical hernia, shifting dullness, fluid wave, masses, and tenderness. The rectum is examined for gross or occult blood.

The upper extremities are examined for Dupuytren contractures Dupuytren Contracture Dupuytren contracture is progressive contracture of the palmar fascial bands, causing flexion deformities of the fingers. Treatment is with corticosteroid injection, surgery, or injections of Neurologic examination includes mental status assessment and evaluation for asterixis a characteristic flapping tremor of the hands.

The skin is examined for jaundice, palmar erythema, needle tracks, vascular spiders, excoriations, xanthomas consistent with primary biliary cholangitis Primary Biliary Cholangitis PBC Primary biliary cholangitis PBC; formerly known as primary biliary cirrhosis is an autoimmune liver disorder characterized by the progressive destruction of intrahepatic bile ducts, leading Severity of illness is indicated mainly by the degree if any of hepatic dysfunction.

Ascending cholangitis is a concern because it requires emergency treatment. Severe hepatic dysfunction is indicated by encephalopathy eg, mental status change, asterixis or coagulopathy eg, easy bleeding, purpura, tarry or heme-positive stool , particularly in patients with signs of portal hypertension Portal Hypertension Portal hypertension is elevated pressure in the portal vein.

Massive upper GI bleeding suggests variceal bleeding Varices Varices are dilated veins in the distal esophagus or proximal stomach caused by elevated pressure in the portal venous system, typically from cirrhosis. They may bleed massively but cause no Ascending cholangitis is suggested by fever and marked, continuous right upper quadrant abdominal pain; acute pancreatitis Acute Pancreatitis Acute pancreatitis is acute inflammation of the pancreas and, sometimes, adjacent tissues.

The most common triggers are gallstones and alcohol intake. The severity of acute pancreatitis is These stones cause biliary colic, biliary obstruction, gallstone Acute jaundice in the young and healthy suggests acute viral hepatitis Overview of Acute Viral Hepatitis Acute viral hepatitis is diffuse liver inflammation caused by specific hepatotropic viruses that have diverse modes of transmission and epidemiologies. Severity of hepatotoxicity after a single acute overdose is predicted by serum Acute jaundice after acute drug or toxin exposure in healthy patients is likely to be due to that substance.

A long history of heavy alcohol use suggests alcohol-related liver disease Alcohol-Related Liver Disease Alcohol consumption is high in most Western countries. A personal or family history of recurrent, mild jaundice without findings of hepatobiliary dysfunction suggests a hereditary disorder, usually Gilbert syndrome Gilbert Syndrome Hereditary or inborn metabolic disorders may cause unconjugated or conjugated hyperbilirubinemia see Overview of bilirubin metabolism.

Unconjugated hyperbilirubinemia: Crigler-Najjar syndrome Gradual onset of jaundice with pruritus, weight loss, and clay-colored stools suggests intrahepatic or extrahepatic cholestasis.

Painless jaundice in elderly patients with weight loss and a mass but with minimal pruritus suggests biliary obstruction caused by cancer. Other examination findings can also be helpful see table Findings Suggesting a Cause of Jaundice Findings Suggesting a Cause of Jaundice Jaundice is a yellowish discoloration of the skin and mucous membranes caused by hyperbilirubinemia.

Blood tests Laboratory Tests of the Liver and Gallbladder Laboratory tests are generally effective for the following: Detecting hepatic dysfunction Assessing the severity of liver injury Monitoring the course of liver diseases and the response to treatment Sometimes biopsy Liver Biopsy Liver biopsy provides histologic information about liver structure and evidence of liver injury type and degree, any fibrosis ; this information can be essential not only to diagnosis but also
