1 Liver and Pancreas








9 AST/ALT > 300 – Viral, toxin-induced, ischemia, meds < 300 – EtOH Hepatitis, cholestasis AST/ALT ratio – > 2 = EtOH – < 1 = Viral or obstructive ABNORMAL LIVER TESTS



12 Alcoholic Hepatitis Jaundice, fever, ascites, HE, AST/ALT > 2 with AST/ALT < 300-400.Increased WBC PATH: Steatosis, Fibrosis,Mallory bodies Treatment: If MDF > 32 start prednisone 40 mg X 4 wks After 7 days on steroids if no improvement and Lillie score >.45 Stop Steroids. If steroids are C/I add pentoxifiline to prevent HRS

13 DILI Acetaminophen Antibiotics: Bactrim, Augmentin, E-cin Phenytoin Valproic acid Immunomodulators INH

14 Viral Hepatitis: Transmission Fecal-Oral: Hepatitis A and E Sexual: Hepatitis B and D; also C (to a lesser extent) Note: Hepatitis D requires coexisting Hep. B infection

15 Viral Hepatitis: Clinical Symptoms include fatigue, anorexia nausea and vomiting Lab shows elevated AST/ALT and bili May resolve, turn fulminant, or become chronic

16 Hepatitis A Fecal-oral transmission Symptoms: Adult > children Transplacental transmission occurs No carrier states, rarely fulminant Can have cholestasis for up to 6 mos Vaccine: Patients with liver dz/risks/ travelers Acute infection: + IgM anti-HAV, Vaccination: + IgG anti-HAV IG prophylactic for Hep A HAV Vaccination 2 doses 6-12 months apart.

17 Hepatitis B Incubation 1-6 months Transmitted sexually, parenterally, mucous membrane exposure Can present with serum sickness (fever, arthritis, urticaria, angioedema) Associated with polyarteritis nodosa (PAN)

18 Extra intestinal Manifestations of Hep B Polyarteritis Nodosa Arthritis Glomerulonephritis Urticaria Mixed Cryoglobulinemia Polyneuropathy


20 Hepatitis B Serology

21 HBV Scenarios HBsAganti-HBsanti-HBc IgM anti-HBc IgG HBeAgDX +-+-+ +--++ -+--- -+-+- --+-- ---+- Acute infection Carrier Vaccinated Exposed Immune Acute Window Exposed Ab lost

22 HepB vaccine/prophylaxis 95% of immunocompetent pts develop antibody (anti-HBs) Only 50% of HD pts develop antibody May be given to pregnant pts 3 doses at 1, 2 and 6 months HBIG Alone: – sexual contacts of carriers and household members of acute Hep B HBIG + vaccine (exposed is HBsAg negative) – blood exposure to pt w/acute Hep B – newborns of Hep B mothers



25 Treatment of CHB HBeAg + HBV DNA > 20000, ALT > 2 x ULN Observe for 6 months and treat if no spontaneous conversion. Consider Liver Bx Rx: Peg IFN o Entecavir, tenofovir, telbivudine Continue Rx for 6 months after seroconversion

26 Treatment of CHB HbeAG – HBV DNA > 20000, ALT > 2 x ULN RX Continue till HBsAG loss


28 Hepatitis C Most common liver disease in the US IVDU, cocaine use, prisons, blood products prior to 1990, tattoo Genotype 1 most common in the US 85 % of Hep C infected become chronic – 25% cirrhosis post 20-25 years of infection – 5 %/yr risk to develop HCC in those with cirrhosis 5% sexual transmission over 10-20 yrs <5% trans placental transmission. HIV co-infection increases transmission rate.

29 Serological Tests Third generation anti-HCV+ >95% sensitive If high pre-test probability and anti-HCV negative can do PCR testing (more often in renal failure or transplant) Genotype testing required for treatment candidates only

30 Extrahepatic Manifestations Glomerulonephritis/MPGN Cryoglobulins Porphyria cutanea tarda (PCT) Thrombocytopenia – Autoantibody – ITP Neuropathy Thyroiditis Sjogren’s Syndrome Inflammatory arthritis



33 Recommended regimen for treatment-naive patients with HCV genotype 1 who are eligible to receive IFN. Daily sofosbuvir RBV plus weekly PEG for 12 weeks is recommended for IFN-eligible persons with HCV genotype 1 infection, regardless of subtype. Recommended regimen for treatment-naive patients with HCV genotype 1 who are not eligible to receive IFN. Daily sofosbuvir RBV for 12 weeks is recommended for IFN- ineligible patients with HCV genotype 1 infection, regardless of subtype.IFN- ineligible

34 Recommended regimen for treatment-naive patients with HCV genotype 3, regardless of eligibility for IFN therapy: Daily sofosbuvir RBV for 24 weeks is recommended for treatment-naive patients with HCV genotype 3 infection. Recommended regimen for treatment-naive patients with HCV genotype 2, regardless of eligibility for IFN therapy: Daily sofosbuvir RBV for 12 weeks is recommended for treatment-naive patients with HCV genotype 2 infection.

35 Hepatitis D Requires coexistent B Usually found in IVDA Coinfection: does not worsen acute Hep B or  risk for chronic state Superinfection: frequently severe/fulminant Dx: Anti-HDV IgM

36 Hepatitis E Monsoon flooding Fecal-oral route No chronic forms Fulminant hepatitis in 3rd trimester of pregnancy

37 A 30 y/o female presents with c/o fatigue,arthralgias,weight loss, amenorrhea. PE reveals Icterus and HSM. No h/o alcohol or drug abuse. No FH of Liver disease.Labs: T.Bili 6mg/dl, AST 300 U/L,ALT350 U/L, ALP 100 U/ml, Albumin 2.9 g/dl. Iron studies are normal. Hepatitis profile and HIV is negative. Which of the following are correct: 1. ANA and ASMA are likely to be positive 2. Liver Biopsy should be done to confirm Dx 3. She will likely respond to steroid therapy 4. All of the above are correct.

38 Autoimmune Hepatitis AIH: Asymptomatic mild disease to Fulminant Liver failure. Fatigue, Jaundice, Maliase Type I:ANA +, ASMA +, Increased IG,SLA/LP Ab Common in USA Type II: LKM1 Common in Europe, poor prognosis, Rx failures RX: Steroids Immunomodulators.


40 Primary Biliary Cirrhosis Usually middle aged women Pruritis, fatigue Increased alk phos The clue: elevated Antimitochondrial Antibodies (AMA) – Anticentromere antibodies – Associated with sicca syndrome and scleroderma Treat with ursodiol

41 Primary Sclerosing Cholangitis An autoimmune fibrosis of large bile ducts Clinical: RUQ pain, fatigue, weight loss 70% of cases associated with ulcerative colitis Increased risk of cholangiocarcinoma Diagnose with ERCP – Beading of the bile ducts on ERCP/MRCP – 10-15% get bile duct carcinoma

42 NAFLD NAFLD: Steatosis NASH: Steatohepatitis Characteristics: Metabolic Syndrome Elevated AST/ALT Liver Biopsy Dx of exclusion: RX: RF Modification Antioxidants Oral hypoglycemics


44 Other liver tests Autoimmune hepatitis (ANA, ASMA, Anti- liver/kidney microsomal, anti-SLA) PBC (AMA) PSC (p-ANCA 70%) Hemochromatosis Iron Saturation >45% Wilsons Disease (low ceruloplasmin, incresed serum and urine Cu) Alfa 1 antitrypsin def ABNORMAL LIVER TESTS

45 Hemochromatosis Most common genetic disease in Caucasians Iron deposits in liver, heart, pancreas, pituitary, Joints Bronze pigmentation, new onset DM,arthritis,hypogonadism. Can lead to cirrhosis and HCC Iron Sat > 45% Increased Ferritin Abnormal Lft’s HFE gene mutation C282Y and H63D RX: Phlebotomy Goal ferritin < 50

46 Wilson’s Disease Rare Autosomal Recessive d/o 1:30000 Increased cooper uptake and decreased biliary excretion. May present as fulminant liver failure Neuropsychiatry symptoms Increased AST/ALT Low ALP Low Cerruloplasmin Increased urinary copper excretion KF rings on slit lamp


48 1 st Trimester2 nd Trimester3 rd Trimester Acute viral hepatitis A-E Acute viral hepatitis A-E Acute viral hepatitis A-E Hyperemesis GVGallstones Herpes Hepatitis ICP AFLP Pre-eclampsia HELLP Liver Diseases in Pregnancy


50 Portal HTN Increased portal blood flow : Increased cardiac index Splanchnic vasodilation Hypervolemia Increased resistance to portal blood flow : Fixed resistance from fibrosis Dynamic resistance RX: NSBB Octreotide Diuretics TIPS

51 Portal HTN Most common cause is cirrhosis Manifestations: Hepatic Encephalopathy Gastro-esophageal Varices Ascites

52 Approach to the Patient with Ascites

53 Workup Need to know if ascites is CHF, cirrhosis or malignancy (exudate) Serum-ascites albumin gradient > 1.1 = transudate (Portal HTN) If ascites protein > 2.5, then CHF If ascites protein < 2.5, then cirrhosis <1.1 = ascites is NOT from portal hypertension – “Higher SAAG = higher pressure” ASCITES

54 Workup Tap all new ascites Tap all ascites in cirrhotics with clinical change Labs – < 250 cells/μl – 1 neutrophil/250 RBC – 2 lymphocyte/750 RBC – Innoculate cultures at the bedside – Gram stain If TB is suspected, you need a peritonal bx ASCITES

55 Treatment 2g Na restriction/day No benefit in restricting fluids Spironolactone 100mg/day + Lasix 40mg/day Large volume paracentesis TIPS for paracentesis-resistant ascites ASCITES

56 SBP Translocation of bacteria across they bowel wall into susceptible ascites. Subclinical Fever, Abd pain,encepahlopathy DX: PMN > 250 GN organisms E.coli most common Treat SBP with 3rd generation cephalosporin IV for 5 day and then PO Abx Pplx with oral quinolones after SBP IV Albumin to prevent HRS.


58 Hepatic Encephalopathy Ppting Factors: GI bleed, SBP, Sepsis, sedatives, constipation, electrolyte abnormalities, acute liver injury, HCC, surgery. RX: Recognize and Correcting ppting factors Correct electrolytes. Lactulose Rifaximin.

59 Hepatorenal syndrome (HRS) HRS Type I: Rapid decline in renal function HRS Type II: Chronic usually due to refractory ascites. DDX: ATN, Pre-renal DX: Sr Creatinine > 1.5 No improvement after holding diuretics and volume expansion with IV Albumin Absence of shock, hypotension,proteinuria,nephrotoxics Low urine sodium.

60 HRS Rx: Avoiding and holding all nephrotoxics. Hold diuretics IV Albumin Midodrine and octreotide OLT is the definitive treatment

61 Fulminant Hepatic Failure Jaundice and hepatic encephalopathy in the absence of chronic liver disease. Acetaminophen is the most common cause in US ( worsened by alcohol, malnutrition and fasting state) Acute viral hepatitis is the most common cause world wide. Other meds: INH, NSAIDS, herbal meds Other causes: AIH, BCS, AFLP, HELLP, Amanita Phalloids

62 Fulminant Hepatic Failure Complications: Hypoglycemia, Cerebral edema,coagulopathy,infection RX; Supportive care in ICU Early recognition and transfer to the transplant center.
