Therefore, identifying patients with clinically significant hepatic fibrosis (fibrosis stage 2 or higher) is important for targeted efforts at preventing disease progression.<br \/>\nNonalcoholic steatohepatitis (NASH), a subtype of NAFLD characterized by inflammation, ballooning, and\u00a0Mallory\u2019s hyaline on liver biopsy, can lead to hepatic fibrosis, cirrhosis, and hepatocellular cancer (HCC). Both NAFLD and NASH are also associated with an increased risk of cardiovascular disease, cardiovascular and liver-related mortality, and impaired health-related quality of life.<\/p>\n<p><!--more--><\/p>\n<p><strong>Screening for advanced fibrosis related to NAFLD\/NASH<\/strong><\/p>\n<p>Primary care, endocrinologists, gastroenterologists, and obesity specialists should screen for NAFLD with advanced fibrosis<\/p>\n<p><strong>Step 1: Identify patients at risk<\/strong><\/p>\n<ul>\n<li>2 or more metabolic risk factors<sup>1<\/sup><\/li>\n<li>Type 2 diabetes<\/li>\n<li>Steatosis on any imaging modality or elevated aminotransferases<\/li>\n<\/ul>\n<p><strong>Step 2: History and laboratory tests<\/strong><\/p>\n<ul>\n<li>Excessive alcohol intake, CBC, liver function tests<\/li>\n<\/ul>\n<p><strong>Step 3: Non-invasive testing (NIT) for fibrosis<\/strong> (FIB-4 is a calculated value4 based on age, AST, ALT &amp; platelet count) <sup>2,3<\/sup><\/p>\n<ul>\n<li>Low risk: FIB-4 &lt;1.3<\/li>\n<li>Indeterminate risk: FIB-4 1.3 to 2.67<\/li>\n<li>High risk: FIB-4 &gt; 2.67<\/li>\n<\/ul>\n<p><strong>Step 4: Liver stiffness measurement (LSM) <\/strong><sup>5,6<\/sup><\/p>\n<ul>\n<li>Low risk: LSM &lt; 8 kPa<\/li>\n<li>Indeterminate risk: LSM 8 to 12 kPa<\/li>\n<li>High risk: LSM &gt; 12 kPa<\/li>\n<\/ul>\n<p><strong>Recommendations<\/strong><\/p>\n<ul>\n<li>Low Risk: Repeat NIT in 2-3 years unless clinical circumstances change<\/li>\n<li>Indeterminate Risk: Refer to hepatologist for liver biopsy or MR elastography or monitoring with re-evaluation of risk in 2-3 years<\/li>\n<li>High Risk: Refer to hepatologist<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Footnotes:<br \/>\n1.

Ultrasound acceptable if vibration-controlled transient elastography (VCTE, FibroScan\u00ae) is unavailable. Consider referral to hepatologist for patients with hepatic steatosis on ultrasound who are indeterminate or high risk based on FIB-4.<br \/>\n6. LSM values are for VCTE (FibroScan\u00ae). Other techniques such as bidimensional shear wave elastography or point shear wave elastography can also be used to measure LSM. Proprietary commercially available blood NITs may be considered for patients considered indeterminate or high risk based on FIB-4 or APRI, or where LSM unavailable.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>References:<\/strong><\/p>\n<ol>\n<li>Kanwal F, Shubrook JH, Adams LA, Pfotenhauer K, Wai-Sun Wong V, Wright E, Abdelmalek MF, Harrison SA, Loomba R, Mantzoros CS, Bugianesi E, Eckel RH, Kaplan LM, El-Serag HB, Cusi K.
