Cycle II, Module C, Course 6 (GIT and abdominal problems) Prof. MUDr. Jiří Horák Seminar 1. Introduction. Examination procedures in GIT and abdominal problems Introduction - clinical and epidemiologic significance of gastrointestinal and abdominal problems - history - typical gastrointestinal and abdominal symptomes, signs and syndromes - physical examination - auxilliary examinations Gastrointestinal symptoms and signs - abdominal pain & colic - weight loss - anorexia - nausea & vomiting - heartburn = retrosternal burning pain - dysphagia & odynophagia - diarrhoea - constipation - flatulence - biliary dyspepsia and colic - disorders of hematopoiesis and hemocoagulation, gastrointestinal bleeding - jaundice - hepatic encephalopathy - abdominal swelling, water retention and ascites - pruritus (itching) - hepatorenal syndrome (functional renal failure) - portal hypertension and esophageal varices bleeding Genitourinary symptoms and signs - change in appearance of the urine - urinary obstruction - anuria (<50 ml urine daily), oliguria, polyuria, nocturia, polakisuria - menstrual problems - lumbar pain - renal colic Laboratory findings a) nonspecific markers of inflammation or malignant growth - erythrocyte sedimentation rate - C-reactive protein - protein electrophoresis 1 Cycle II, Module C, Course 6 (GIT and abdominal problems) Prof. MUDr. Jiří Horák - blood count - serum complement concentration (decreased in arthritis, vasculitis, nephritis) - other acute-phase proteins (fibrinogen, ferritin, haptoglobin, coeruloplasmin, alpha-1 antitrypsin etc.) are not used for inflammatory activity assessment b) functional examination - gastric chemistry - pancreozymin-secretin test - bentiromide test - chromoexcretory tests of liver function (bromphtalein, indocyanine green, rose bengal, IDA-derivatives) - metabolic tests of liver function: galactose test, antipyrine test - pH-metry - stool examination for fat and residues - xylose test - beta-carotene - hemocoagulation c) tests for GIT bleeding - benzidine test - Hemoccult d) protein exudation into the GIT - radioactive chromalbumin test e) the so-called liver function tests - bilirubin - ALT, AST - GMT, ALP - other tests useful in diagnosis and monitoring of liver disease: blood count, serum protein, hemocoagulation tests, iron, creatinine, glucose, triglycerides, cholesterol, ammonia, bile acids f) pancreas examination - amylase - lipase g) urine chemistry - bilirubin - urobilinogen - protein - glucose - keton bodies h) antibodies and autoantibodies (cf. table Antibodies and autoantibodies in autoimmune hepatitis) - ANA - ASMA - AMA - typically in primary biliry cirrhosis - ANCA (p, c) 2 Cycle II, Module C, Course 6 (GIT and abdominal problems) Prof. MUDr. Jiří Horák - against thyroid tissue - against gastric mucosa - against intrinsic factor - LKM antibodies etc. i) serology and molecular biology of viral hepatitis - hepatitis A - hepatitis B - hepatitis C - hepatitis D - hepatitis E - hepatitis G - TTV-hepatitis j) tests for Helicobacter pylori - histology - antibodies - urease test - breath tests k) microbiological examination - stools - ascites - bile - urine - other l) serological tests in microbiological diagnostics m) tests in metabolic diseases - hepatic porphyrias - Wilson's disease - genetic hemochromatosis - cystic fibrosis - alpha-1 antitrypsin deficiency n) tumour markers - alpha-fetoprotein - hepatocellular carcinoma - carcinoembryonic antigen - colorectal carcinoma - Ca 19-9 - pancreatic carcinoma - Ca 125 - gynecological carcinomas, carcinoma of the liver, pancreas and lungs - gastrin - gastrinoma - C-peptide – insulinoma Imaging methods, endoscopy and biopsy - abdominal sonography - endosonography - X-ray of the esophagus 3 Cycle II, Module C, Course 6 (GIT and abdominal problems) Prof. MUDr. Jiří Horák - plain abdominal X-ray X-ray of the stomach and duodenum gastrointestinal transit enteroclysis irrigography ERCP PTC CT NMR arteriography cavography lymphography splenoportography peroral cholecystography and intravenous cholangiography static hepatic scintigraphy cholescintigraphy esophagogastroduodenoscopy colonoscopy rectosigmoidoscopy laparoscopy blind and guided biopsy of the abdominal organs Pressure measurements - in the GIT (esophagus, sphincter of Oddi, rectum) - in the portal vein (directly, wedged hepatic vein pressure) Histologic and cytologic examination - esophageal mucosa - gastric mucosa - duodenal mucosa - jejunal and ileal mucosa - colonic mucosa - liver and biliary tree - pancreas - ascites 4 Cycle II, Module C, Course 6 (GIT and abdominal problems) Prof. MUDr. Jiří Horák Appendix INDICATION AND INTERPRETATION OF VIRAL HEPATITIS MARKER EXAMINATION Hepatitis A - anti-HAV IgM - anti-HAV IgG Hepatitis B - HBsAg - HBeAg - anti-HBc IgM - anti-HBc IgG - anti-HBc total - HBV DNA - quantitative viremia - anti-HBs - anti-HBe - interpretation of the results cf the table Hepatitis C - anti-HCV - anti-HCV IgM - RIBA (recombinant immunoblot assay) - HCV RNA - genotype - quantitative viremia Hepatitis D - anti-HDV - anti-HDV IgM - HDV RNA - coinfection HBV + HDV: anti-HBc IgM + anti-HDV - HDV superinfection on standing HBV infection: anti-HBc IgG + anti-HDV Hepatitis E - anti-HEV total - anti-HEV IgM - anti-HEV IgG Hepatitis G - HGV RNA 5 Cycle II, Module C, Course 6 (GIT and abdominal problems) Prof. MUDr. Jiří Horák TTV-hepatitis (Transfusion-transmitted virus) - TTV DNA Differential diagnosis of viral hepatitis - acute viral hepatitis: EB-virus, herpes simplex virus, cytomegalovirus, coxsackie virus - autoimmune hepatitis - toxic hepatitis (toxins, drugs, alcohol) - primary biliary cirrhosis - primary sclerosing cholangitis - Wilson's disease - hepatic porphyrias - biliary tree obstruction 6 Cycle II, Module C, Course 6 (GIT and abdominal problems) Prof. MUDr. Jiří Horák Antibodies in autoimmune hepatitis antibody antigen AIH type I AIH type II AIH t.
