Abdomen Notes Flashcards
Autoimmune hepatitis:
features? (5)
treatment? (2)
- signs of chronic liver disease
- acute hepatitis: fever, jaundice, etc (25%)
- amenorrhoea (common)
- ANA/SMA/LKM1 antibodies, raised IgG levels
- liver biopsy: inflammation extending beyond limiting plate
- steroids, other immunosuppressants, e.g. azathioprine
- liver transplant
Coeliac disease:
definitive diagnosis? (1)
conditions associated? (2)
normally combination of immunology and biopsy but mainly= duodenal biopsy
- dermatitis herpetiformis (vesicular, pruritic skin eruption)
- autoimmune disoders (type 1 DM/ autoimmune hepatitis/ Graves)
- have to eat gluten diet 6 weeks prior to test
- tissue transglutaminase (TTG) and antibodies (IgA)
- needed to look for selective IgA deficiency, which would give a false negative coeliac result
- IgA deficiency (common in Coeliacs) would mean that anti-tTG antibodies are low (both low)
Coeliac disease:
what does positive biopsy show? (4)
- villous atrophy
- crypt hyperplasia
- increase in intraepithelial lymphocytes
- lamina propria infiltration with lymphocytes
Ulcerative colitis:
main side effect amiosalicylate, mesalazine?
others? (6)
agranulocytosis
- do FBC
upset, headache, agranulocytosis, pancreatitis*, interstitial nephritis
Janundice causes and poo/wee colour of:
pre-hepatic?
hepatic?
post-hepatic?
PRE = normal wee + poo
- Gilbers
- haemolytic anaemia
HEPATIC = dark urine + normal poo
- hereditary hepatitis
- drug induced hepatitis
- acute hepatitis
- infecitous hepatitis
- neoplasm
POST = dark urine + pale poo bile duct obstruction - lithases/ stenosis - pancreatitis - cholanglocarcinoma - duodenal/pancreatic mass/ neoplasm/ abscess - cholecystitis/colangitis
Alcohol and the liver:
typical progression? (3)
usual liver test results? (1)
management? (1)
alcoholic fatty liver disease –> alcoholic heptitis –> cirrhosis
AST:ALT ratio of 2:1 usually with raised gamma-GT
- glucocorticoids (e.g. perdnisolone)
Barretts oesophagitis:
what is it?
management? (3)
- metaplasia of the lower oesophageal mucosa, with the usual squamous epithelium being replaced by columnar epithelium
- risk of progressin to adenocarcinoma
- endoscopic surveillance with biopsies if metaplasia (but not dysplasia) every 3-5 years
- PPI
- if dysplasia –> endoscopic mucosal resection and radiofrequency ablation
