Dyspepsia, Peptic ulcer, gastroparesis Flashcards
presentation of dyspepsia
upper abdominal pain or discomfort, heartburn,
acid reflux,
nausea
vomiting.
Uncomfortable feeling in epigastric area resulting from impaired digestion
common causes of peptic ulcer disease
H.Pylori infection
LT use of NSAIDs
presentation/symptoms of peptic ulcer disease
BURNING or GNAWING pain
risk factors for dyspepsia
Younger age
Female sex
Higher levels of somatoform-type symptoms reporting
IBS
Psychological comorbidity (new onset symptoms more likely in those with history of anxiety or depression)
Enteric Infection
High BMI
NSAIDs
H. Pylori (although this is organic cause but many people have symptoms following erradicaition)
pathophysiology of dyspepsia is uncertain, but there is a proposed model. True or False
true
H pylori is gram negative. true or false
true
how is h pylori spread
oral-oral / faecal oral
infection with h pylori recruits what type of wbcs
neutrophils
neutrophilic gastritis
Diagnosis of H.Pylori infection
Gastric biopsy:
Urease test
Histology
Culture/sensitivity
Urease breath test
FAT (faecal antigen test)
Serology (IgA antibodies) not accurate with increasing patient age
CLO test - urease test
H. pylori increases pH of its microenvironment
Secretes urease which catalyzes conversion of urea to ammonia
Urease test changes acid to ammonium bicarbonate
treatment of peptic ulcer disease
All get antisecretory therapy (PPI)
All get tested for presence of H. pylori
H.pylori +ve – eradicate and confirm
H. pylori –ve – antisecretory therapy
Stop NSAIDS
Lifestyle changes
Non-HP/non-NSAID ulcers – nutrition and optimise comorbidities
No firm dietary recommendations
Surgery infrequent
treatment of H.Pylori infection (eradication therapy)
“Triple therapy” for 1 week commonest (85% success)
1st line: PPI, amoxicillin and either clarithromycin or metronidazole
2nd line: PPI, amoxicillin and whichever wasn’t used first line
3rd line “quadruple therapy”: PPI, bismuth subsalicylate (unlicensed) and either 2 antibiotics not used previously or rifabutin or furazolidone
S/E’s common (nausea, diarrhoea): compliance
If still symptomatic – re-test
complications of peptic ulcer disease
anaemia
vleeding
perforation
gastric outler/ duodenal obstruction / fibrotic scar
