4. Chronic gastritis is a polyetiologic diseases
with nonspecific chronic inflammation of
the stomach lining due to influence of
endo- and exogenic factors and may be
predictors of PUD or cancer
5. Classification CH G
(R.G. Strickland и J.R. Mackay,1973)
ChG
A (15%)
autoimmune
B (80%)
HP dependent
C (5%)
chemical-toxic
8. Helicobacter pylori (H. pylori)
A gram-negative, helical, rod-shaped bacterium, colonizes
the gastric mucosa of approximately one-half of the world
population and an estimated 30% to 40% of the U.S.
population.
H. Pylori is present in 95% of patients with duodenal ulcers
and in 70% of those with gastric ulcers.
It is typically transmitted via the fecal-oral route during
early childhood and persists for decades.
The bacterium is a known cause of gastric and duodenal
ulcers
HP is a risk factor for mucosa-associated lymphoid tissue
(MALT) lymphoma and gastric adenocarcinoma.
9. Due to HP
Primary contagious damage of epit cells
Activation of inflammatory cascades
Increase production of gastrine by G cells
and HCl and pepsin by parietal cells
Cellular regeneration abnormalities
10. Nonsteroidal anti-inflammatory
drugs (NSAIDs)
Aspirin (more than 300 drug products contain some form
of aspirin)
Nonsteroidal anti-inflammatory drugs (NSAIDs, such as
ibuprofen or naproxen)
Steroids (prednisone is one example)
Potassium supplements
Iron tablets
Cancer chemotherapy medications
11. Swallowing poisons or objects
Corrosives (acid or lye)
Alcohols of various types
Swallowed foreign bodies (paper clips or pins)
Medical and surgical conditions
Physical stress in people who are critically ill or injured
After medical procedures (such as endoscopy, in which a
specialist looks into the stomach with a small lighted tube)
After an operation to remove part of the stomach
After radiation treatment for cancer
Autoimmune diseases
Pernicious anemia
Chronic vomiting
12. CF
AP syndrome
AP or discomfort in the epigastric region
Irradiation - to the back
Character of pain - burning, aching,
gnawing, sharp, stabbing, or cutting.
Duration – 1-2 h
13. Dyspepsia
Belching: Belching usually either does not
relieve the pain or relieves it only briefly.
Nausea and vomiting: The vomit may be
clear, green or yellow, blood-streaked, or
completely bloody, depending on the
severity of the stomach inflammation.
Bloating
Feeling of fullness or burning in the upper
part of the belly
14. Exam-n
Blood cell counts (looking mostly for anemia, a low
blood count)
Liver and kidney functions
Urinalysis
Gallbladder and pancreas functions
Pregnancy test
H pylori tests
Stool, for blood
X-rays
ECG
Endoscopy.
15. Indications for Diagnosis and Treatment of H. pylori
Established (Am J Gastroenter 2007;102:1808–1825 )
Active peptic ulcer disease (gastric or duodenal ulcer)
Confirmed history of peptic ulcer disease (not previously
treated for H. pylori)
Gastric MALT lymphoma (low grade)
After endoscopic resection of early gastric cancer
Uninvestigated dyspepsia (depending upon H. pylori
prevalence)
Controversial
Nonulcer dyspepsia
Gastroesophageal reflux disease
Persons using nonsteroidal antiinflammatory drugs
Unexplained iron deficiency anemia
Populations at higher risk for gastric cancer
16. Diagnostic Testing for H pylori
Antibody testing (quantitative and qualitative)
Urea breath tests
Fecal antigen test
17. NM Treatment
H. pylori eradication .
NSAIDs are treated by stopping the drug and using antacids,
histamine blockers or proton pump inhibitors or PPIs,
Home remedies (for example, over-the-counter antacids or
histamine blockers) for gastritis usually do not treat the underlying
cause, but reduce symptoms.
Stop cigarette smoking.
Avoid drinking excessive amounts of alcohol.
Avoid caffeinated, decaffeinated, and carbonated dinks; and fruit
juices that contain citric acid, for example, grapefruit, orange,
pineapple, etc.
Avoid high-fat foods.
The growth of H. pylori may be stopped by a diet rich in fiber, and
foods that contain flavonoids, for example:
Certain teas, Onions, Garlic, Berries, Celery, Kale, Broccoli, Parsley,
Thyme, Soy foods, Legumes
