Discussion
Chronic liver disease Duration of liver disease (typically >3-6 mo) or by evidence of chronic hepatic decompensation ( hypoalbuminemia , thrombocytopenia) or physical stigmata of chronic liver disease (clubbing, spider telangiectasia , hepatosplenomegaly ).
CAUSES OF CHRONIC HEPATITIS CHRONIC VIRAL HEPATITIS Hep C Hep D Hep B AUTOIMMUNE HEPATITIS Antibody positive Antiactin Anti-liver-kidney microsomal antibody positive Antisoluble liver antigen antibody positive Overlap(includes antibody to liver specific lipoprotein or asialoglycoprotein ) Overlap syndrome with sclerosing cholangitis and autoantibodies Systemic lupus erythematosus Celiac disease
DRUG INDUCED HEPATITIS Isoniazid Methyldopa Sulfonamid Dantrolene Nitrofurontine
METABOLIC DISORDERS ASSOCIATED WITH CHRONIC LIVER DISEASE Wilson disease Alpha 1 antitrypsin deficiency Tyrosinemia Niemann -pick disease type 2 Glycogen storage disease type 4 Cystic fibrosis Galactosemia NON ALCHOLIC STETOHEPATITIS (OBESITY & INSULIN RESISTANCE)
Autoimmune Hepatitis “Chronic hepatic inflammatory process manifested by elevated serum amino transaminase, liver-associated serum autoantibodies, and/or hypergammaglobulinemia .” The target of the inflammatory process can include hepatocytes and to a lesser extent bile duct epithelium .
Chronicity is determined either by Duration of liver disease (typically >3-6 mo) or by evidence of chronic hepatic decompensation hypoalbuminemia , thrombocytopenia) or physical stigmata of chronic liver disease (clubbing, spider telangiectasia , hepatosplenomegaly ). The severity is variable; T he affected child might have only biochemical evidence of liver dysfunction, might have stigmata of chronic liver disease, or can present in hepatic failure.
CLASSIFICATION OF AUTOIMMUNE HEPATITIS VARIABLE TYPE 1 AUTOIMMUNE TYPE 2 AUTOIMMUNE HEPATITIS HEPATITIS Characteristic autoantibodies Antinuclear antibody Antibody against liver -kidney microsome 1* Smooth-muscle antibody Antiactin antibody Antibody against liver cytosol Antibodies against soluble liver antigen &liver pancrease antigen Atypical perinuclear antineutrophil cytoplasmic antibody Geographic variation worldwide worldwide Age at presentation Any age predominnantly childhood and young adulthood Sex female 75 % cases female 95% cases Association with other autoimmune diseases common common Clinical severitybroad range generally severe Histopathologic features at presentation broad range generally advanced Treatment failure infrequent frequent Relapse after drug withdrawl variable common Need for long term maintainance variable 100%
CLINICAL MANIFESTATION Most cases have an insidious onset. May be asymptomatic or have nonspecific symptoms ( eg , fatigue, anorexia, weight loss, behavioral changes, amenorrhea) Extrahepatic manifestation (arthritis . vasculitis ,nephritis , coombs + ve anemia and rash) Clinical features of autoimmune hepatitis widely vary.
Common findings on physical examination are as follows: Hepatomegaly (83%) Jaundice (69%) Splenomegaly (32%) Spider Nevi (58%) Ascites (20%) Encephalopathy (14%)
Complications may include the following: Cirrhosis and complications of cirrhosis ( eg , ascites , coagulopathy , hepatic coma) Portal hypertension Esophageal varices Malnutrition (with poor growth in children)
LAB FINDINGS Raised serum aminotransferases (in asymptomatic cases 100-300 IU/L ,>1000 IU/L can be seen in symptomatic pt) Serum bilirubin concentration (predominantly direct fraction) commonly 2-10 mg /dl ALP & GGT are normal to slightly increased Prolonged Prothrombin time Hypoalbuminemia Hypergammaglobinemia Serum IGg usually >16 g/dl Autoantibody ANA ,ASMA ,LKMA ,PANCA
MANAGEMENT PREDNISOLONE 1-2 mg /kg continue until amintransferase values returns to less than twice the upperlimit of normal Dose should then be tapered in 5mg decrements over 2-4 month until maintenance dose of 0.1 -0.3 mg /kg /24hr achieved
AZATHIOPRINE (1.5 -2 mg /kg/24 hr,up to 100mg /24 hr) or 6 MERCAPTOPURINE 1 – 1.5 mg /kg/24 hr ) can be added in pt who respond poorly,experience severe side effects or who can not maintained on low dose steroids Cases Refractory to standard therapy : BUDESONIDE ,CYCLOSPORINE,TACROLIMUS ,MYCOPHENYLATE MOFETILE
