A 27-year-old man with no significant past medical history presented as a referral from a community hospital for evaluation of hepatitis, initially diagnosed as choledocholithiasis. The patient complained of fever, chills, and abdominal pain (achy in the Right Upper Quadrant and epigastrium) for the past 2 weeks, nausea, and vomiting of clear liquids without blood for a 1 week, and jaundice for 2 days. Records from referring facility indicated that patient had MRCP-Magnetic Resonant Cholangio Pancreatography that demonstrated cholelithiasis, but it did not show any signs of cholecystitis. An abdominal ultrasound revealed sludge and gallstones in the gallbladder.\nFurther questioning revealed that patient had been studying to be a physical trainer at a local college. He exercised vigorously at least 3 times/week. Patient stated that he was “prescribed” a set of supplements (Hydroxycut, Black powder, mitotropin, xenadrine, arson, and L-glutamine powder 23) by his local nutrition center.\nAfter admission in the hospital, hepatology consult was called. When patient was admitted, liver enzymes panel showed: AST-Aspartate Aminotransferase: 3800 U/L, ALT-Alanine aminotransferase: 5100 U/L, total bilirubin: 14.7 mg/dl, direct bilirubin: 10.0 mg/dl and alkaline phosphatase: 99 mg/dl, all correlated with the degree of jaundice seen. Additional tests included a urine toxicology screen, immunological studies for liver (anti-nuclear antibodies, anti-smooth muscle antibodies, and anti A liver/kidney microsomal antibodies), serum acetaminophen level, serum ceruloplasmin level, and genetic tests for hemochromatosis; all of them were negative. Liver biopsy showed signs of acute liver failure.\nHematoxylin and eosin stain of the liver biopsy specimen is shown in Figures and . shows extensive patchy areas of necrosis as in acute fulminant hepatitis with sparing of biliary tract. shows lymphocytic infiltration of the portal tracts and lobular parenchyma.\nPatient was asymptomatic during the hospital stay and was planned to discharge with trending down of liver enzymes by discontinuation of Hydroxycut and conservative management. The patient was advised to follow-up with Hepatology. On follow-up visit after 2 weeks of discharge, Labs: AST: 669 U/L, ALT: 1965 U/L, Total Bilirubin: 4.5 mg/dl, Alkaline phosphatase: 128 mg/dl, PT: 1.1.
A 36-year-old female with no significant medical history presented with a 3-day history of low-grade fever, nausea, vomiting, and abdominal pain. She reported that she had been following a 500 Kcal diet and was taking GC for four weeks to lose weight. She also complained of fatigue, anorexia, and jaundice. The patient denied any history of recent blood transfusion, illicit drug use, or family history of liver disease. She denied alcohol consumption and was in a monogamous heterosexual relationship.\nOn physical examination, she had scleral icterus, cutaneous jaundice, and tender hepatomegaly measuring 2 cm below the costal margin. Abnormal laboratory results included white blood cell count of 2.73 × 103 cells/μL (4–11) and platelet count of 78 × 103 cells/μL (150–400), aspartate aminotransferase (AST) of 5340 U/L (15–41), alanine aminotransferase (ALT) of 5615 U/L (7–52), alkaline phosphatase of 104 U/L (32–91), total bilirubin of 7.4 mg/dl (0.3–1.0), and direct bilirubin of 4.9 mg/dl (0.0–0.4). Serologies for hepatitis A, hepatitis B, hepatitis C, autoimmune markers (anti-nuclear antibody, anti-smooth muscle antibodies, anti-mitochondrial antibody, and anti-liver kidney microsomal 1 antibody), human immunodeficiency virus, rapid plasma reagin test, cytomegalovirus, Epstein-Barr virus, Herpes Simplex virus, and Parvovirus were negative. Serum ceruloplasmin, alpha-fetoprotein, and alpha-1 antitrypsin levels were normal. Abdominal Doppler ultrasound showed mild echotexture coarsening in the liver and small ascites.\nConsidering her recent exposure to herbal medications, we suspected drug induced liver injury and used updated RUCAM (Roussel Uclaf Causality Assessment Method) scale to calculate its probability. Patient's RUCAM score came out to be 8 points, which is consistent with probable drug induced liver injury []. GC was discontinued and conservative management was initiated. Significant clinical improvement and the downward trend of liver function tests obviated the need for liver biopsy. The patient was discharged on hospital day 6. At follow-up visit two weeks later, her liver function tests had returned to normal ().
