Details</a></p></div></div><div class="body-content whole_rhythm" itemprop="text"><div id="GreenTea.OVERVIEW"><h2 id="_GreenTea_OVERVIEW_">OVERVIEW</h2><div id="GreenTea.Introduction"><h3>Introduction</h3><p>Green tea is a popular and commonly consumed drink and its extract is found in many herbal and dietary supplements (HDS). Green tea extract and, more rarely, ingestion of large amounts of green tea have been implicated in cases of clinically apparent acute liver injury, including instances of acute liver failure and either need for urgent liver transplantation or death.</p></div><div id="GreenTea.Background"><h3>Background</h3><p>Both green tea and black tea are produced from the leaves of the Chinese tea tree Camellia sinensis. Green tea, unlike black tea, is unfermented, which helps to preserve its antioxidant polyphenolic catechols. Green tea has long been believed to have health restoring properties and its ingredients to have antioxidant activity. For this reason, extracts of green tea have been used as an herbal medication alone and in combination with other herbals and dietary supplements which are purported to improve health, prevent cancer and heart disease, decrease serum lipid levels, promote weight loss, decrease periodontal disease and even treat clostridial diarrhea. Green tea extract (GTE) is listed in more than 100 over-the-counter herbal preparations, but is not approved for any specific medical indication and is not regulated in regards to efficacy and safety by the FDA. The multiple polyphenols in green tea are believed to be the active components responsible for its purported chemoprotective, antiproliferative and antioxidant properties. The mechanism by which green tea may have such effects has not been elucidated. Human clinical studies demonstrate that single doses of up to 1.6 grams of green tea extract are well tolerated. The maximum tolerated dose in humans is reported to be 9.9 grams per day; a dose equivalent to 24 cups of green tea. Side effects of high doses of green tea extract are usually mild and include headache, dizziness and nausea. The safety and tolerability of long term use of green tea extracts has not been well defined.</p></div><div id="GreenTea.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Drinking green tea has not been associated with liver injury or serum aminotransferase elevations; indeed, cross sectional studies suggest that regular use of green tea is associated with lower serum ALT and AST values. Nevertheless, case series and a systematic review by the United States Pharmacopeia have raised the issue of the potential for GTE to cause hepatotoxicity. In a large prospective study of GTE in postmenopausal woman at risk for breast cancer, GTE was associated with ALT elevations in 6.7% of patients compared to 0.7% of controls. In these studies, clinically apparent liver injury was not observed, but the extract was quickly discontinued in patients with ALT elevations. Restarting GTE in a proportion of patients was followed by rapid recurrence of ALT elevations that resolved again with stopping.</p><p>The prevalence of green tea extract induced acute liver injury with symptoms or jaundice is not known, but is undoubtedly low in comparison to the wide scale use of these products. Nevertheless, more than 100 instances of clinically apparent liver injury attributed to GTE have been reported in the literature. Liver injury typically arises within 1 to 6 months of starting the product but longer and shorter latencies (particularly with reexposure) have been reported. The majority of cases present with an acute hepatitis-like syndrome and a markedly hepatocellular pattern of serum enzyme elevations. Most patients recover rapidly upon stopping the extract or HDS, although fatal instances of acute liver failure have been described. Biopsy findings show necrosis, inflammation, and eosinophils in a pattern resembling acute hepatitis. Immunoallergic and autoimmune features are usually absent or minimal. A small number of similar cases have also been described after drinking green tea “infusions” rather than taking oral preparations of extracts of green tea.</p><p>The most prominent regulatory action against green tea containing products concerned Exolise, a weight loss product which was withdrawn from Spain and France in 2003. Also, green tea is an ingredient in many over-the-counter weight loss agents with names such as Hydroxycut, Dexatrim, Slimquick, Slimcut Fat Burner, The Right Approach, Mega Green Tea and Green Tea Fat Burner, among others, which have been implicated in causing rare instances of clinically apparent acute liver injury.</p><p>Likelihood score: A (well established cause of clinically apparent liver injury).</p></div><div id="GreenTea.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>Preclinical and human data implicate the catechin component of green tea as the culprit of hepatotoxicity. Approximately 10% of the green tea extract is composed of catechins; of these, epigallocatechin-3-gallate (EGCG) is present in highest concentration. There is great variability in the concentration of green tea extract, EGCG and other components among marketed products, which may explain while some products have been implicated in hepatotoxicity. Exposure of rat hepatocytes to EGCG has been shown to induce mitochondrial toxicity and generation of reactive oxygen species. The close association of liver injury from green tea with the HLA allele B*35:01 suggests an immunologic etiology. This HLA association, the lack of clear cut dose dependency and the recurrence of injury on reexposure (with a shorter latency) indicates that the injury is idiosyncratic and not due to direct toxicity of the catechins. The pathogenesis of green tea associated liver injury is an area of current, active investigation.</p></div><div id="GreenTea.Outcome_and_Management"><h3>Outcome and Management</h3><p>Given the wide spread consumption of green tea and its extract in various HDS, liver injury from green tea is rare. Patients who present with acute liver injury, particularly with a hepatocellular pattern without an obvious cause, should be asked about the use of HDS and green tea extract, and should be advised to stop all herbal medications. In those drinking green tea regularly, stopping all use is prudent. In typical cases, recovery is expected in one to two months. As in any case of drug induced liver injury, the presentation with or development of abnormal liver function, deep jaundice, abnormal mentation suggestive of encephalopathy, prolongation of the prothrombin time or elevation of the INR, and a depressed albumin, should prompt referral for liver transplantation. Patients who developed acute liver injury attributable to green tea extract should be cautioned about reexposure and avoidance of HDS that might include green tea.</p><p>Drug Class: <a href="/books/n/livertox/HerbalDietarySuppl/?report=reader">Herbal and Dietary Supplements</a></p></div></div><div id="GreenTea.CASE_REPORTS"><h2 id="_GreenTea_CASE_REPORTS_">CASE REPORTS</h2><div id="GreenTea.Case_1_37_year_old_woman_with_a"><h3>Case 1. 37 year old woman with acute hepatitis after using weight loss supplement.(<a class="bibr" href="#GreenTea.REF.1" rid="GreenTea.REF.1">1</a>)</h3><p>A 37 year old woman developed nausea, abdominal pain and jaundice 4 months after starting a weight loss supplement called The Right Approach Complex (Pharmanex, Provo, Utah), the major component of which was green tea extract (“TeGreen”). She denied a history of liver disease, alcohol use, and risk factors for viral hepatitis. On examination, she was jaundiced but had no fever or rash. Laboratory tests showed serum bilirubin of 11.7 mg/dL and marked elevations in serum aminotransferase levels (~20 times ULN), with minimal increases in alkaline phosphatase (Table). Tests for hepatitis A, B and C were negative as were autoantibodies, except for antinuclear antibody which was weakly positive (1:40, speckled pattern). Liver biopsy revealed marked interface necrosis and inflammation and mild lobular inflammation. Cholecystectomy and intraoperative cholangiography were performed. The patient began to improve rapidly and was discharged after two weeks in the hospital. One month later, liver tests had improved significantly. One year later, she was again admitted with a one week history of abdominal pain and jaundice. She admitted to resuming The Right Approach Complex one month earlier, but stopped taking it one week before presentation when she developed dysphagia. On admission, she was jaundiced. She again improved rapidly and six months later all liver tests were normal.</p><div id="GreenTea.Key_Points"><h4>Key Points</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figGreenTeaTc"><a href="/books/NBK547925/table/GreenTea.Tc/?report=objectonly" target="object" title="Table" class="img_link icnblk_img" rid-ob="figobGreenTeaTc"><img class="small-thumb" src="/corehtml/pmc/css/bookshelf/2.26/img/table-icon.gif" alt="Table Icon" /></a><div class="icnblk_cntnt"><h4 id="GreenTea.Tc"><a href="/books/NBK547925/table/GreenTea.Tc/?report=objectonly" target="object" rid-ob="figobGreenTeaTc">Table</a></h4></div></div></div><div id="GreenTea.Laboratory_Values"><h4>Laboratory Values</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figGreenTeaTd"><a href="/books/NBK547925/table/GreenTea.Td/?report=objectonly" target="object" title="Table" class="img_link icnblk_img" rid-ob="figobGreenTeaTd"><img class="small-thumb" src="/corehtml/pmc/css/bookshelf/2.26/img/table-icon.gif" alt="Table Icon" /></a><div class="icnblk_cntnt"><h4 id="GreenTea.Td"><a href="/books/NBK547925/table/GreenTea.Td/?report=objectonly" target="object" rid-ob="figobGreenTeaTd">Table</a></h4></div></div></div><div id="GreenTea.Comment"><h4>Comment</h4><p>This case demonstrates the typical acute viral hepatitis-like presentation of green tea hepatotoxicity with jaundice, accompanied by marked elevations in serum aminotransferase levels and minimal increases in alkaline phosphatase.

She had a remote history of an acute hepatitis of unknown cause 8 years earlier and a previous cholecystectomy. She had no other medical illnesses or drug allergies, took no prescription medications or other over-the-counter products, did not drink alcohol, and had no known risk factors for viral hepatitis. After several days of symptoms she stopped the supplement and sought medical attention 10 days later. On presentation, she was jaundiced but had no fever, rash or signs of chronic liver disease. Her body mass index was 40.7 kg/m<sup>2</sup>. Blood testing showed a total bilirubin of 6.3 mg/dL, ALT 2325 U/L, AST 2548 U/L and alkaline phosphatase 197 U/L (R ratio=20.9: hepatocellular). Tests for hepatitis A, B, C and E were negative. Both ANA and AMA were negative, while SMA was weakly positive (1:20). The INR was 1.5. She was initially followed as an outpatient, but with worsening symptoms and liver tests she was admitted and treated with N-acetyl cysteamine (Table). An ultrasound and CT scan of the abdomen showed hepatomegaly, but no evidence of biliary obstruction. Serum bilirubin rose to 26.7 mg/dL and INR to 1.7. A liver biopsy showed severe acute hepatitis with bridging necrosis but no fibrosis. She was not treated with corticosteroids and improved slowly. Jaundice persisted for more than a month but then resolved and at follow up at 6 months, liver tests were normal except for mild alkaline phosphatase elevations.</p><div id="GreenTea.Key_Points_2"><h4>Key Points</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figGreenTeaTg"><a href="/books/NBK547925/table/GreenTea.Tg/?report=objectonly" target="object" title="Table" class="img_link icnblk_img" rid-ob="figobGreenTeaTg"><img class="small-thumb" src="/corehtml/pmc/css/bookshelf/2.26/img/table-icon.gif" alt="Table Icon" /></a><div class="icnblk_cntnt"><h4 id="GreenTea.Tg"><a href="/books/NBK547925/table/GreenTea.Tg/?report=objectonly" target="object" rid-ob="figobGreenTeaTg">Table</a></h4></div></div></div><div id="GreenTea.Laboratory_Values_2"><h4>Laboratory Values</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figGreenTeaTh"><a href="/books/NBK547925/table/GreenTea.Th/?report=objectonly" target="object" title="Table" class="img_link icnblk_img" rid-ob="figobGreenTeaTh"><img class="small-thumb" src="/corehtml/pmc/css/bookshelf/2.26/img/table-icon.gif" alt="Table Icon" /></a><div class="icnblk_cntnt"><h4 id="GreenTea.Th"><a href="/books/NBK547925/table/GreenTea.Th/?report=objectonly" target="object" rid-ob="figobGreenTeaTh">Table</a></h4></div></div></div><div id="GreenTea.Comment_2"><h4>Comment</h4><p>This patient had a severe and prolonged hepatitis arising within a month of starting a popular commercial, multiingredient, weight loss product containing green tea extract. The estimated dose was 800 mg daily for 3 to 4 weeks. The liver injury was judged to be highly likely due to green tea extract. The ingredients of the product included multiple herbal extracts including green tea, Asian ginseng, beeswax, bilberry, blueberry, eleuthero, elderberry, Yerba mate, pomegranate and Schisandra chinensis. HLA typing showed homozygosity for HLA-B*35:01. Severity was scored as 4+ (jaundiced, INR >1.5). Chronicity was scored as possible or minimal based upon the alkaline phosphatase levels. The short latency and medical history of acute hepatitis of unknown cause in the past suggests a previous episode of green tea related liver injury, so that this episode may have represented recurrence on reexposure.</p></div></div></div><div id="GreenTea.PRODUCT_INFORMATION"><h2 id="_GreenTea_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
