Stomach :more then 90% of gastric ulcer occur in the lesser
curvature
Duodenum :90-95% of duodenal ulcer occur the first portion of
duodenum

•500000 American people new cases per year
•Decrease range of peptic ulcer with treatment in 50% in last 30years
•Decrease recurrence with treatment
•Increase range of duodenal ulcer to gastric ulcer 5:1
•95% common in pyloric channel
•Duodenal ulcer increase 30-55years more in female 1,3 :1

Fundus and antrum : parietal cell : secretion HCL and IF
Body : chief cell : secretion pepsinogen
Antrum : G cell : secretion gastrin
D cell : somatostatin
Mucus cell : mucus
Important secretion of stomach : HCL and pepsinogen
Physiology of stomach

Cephalic phase :
1.Visual of food
2.Smell of food
3.Taste of food
Gastric phase :this phase of two mechanism
When food inter to stomach
amino acid of Food can secretion of gastrin
Duodenal phase :
•When food enter to intestine this can stretch and distension of
intestine
Stage of HCL secretion

Epithelial
Increase cellular resistant
Prevention of HCL diffusion by mucus surpece
Repairing : by stomach epithelium
Growth factors :secretion of GH factors for increasing epithelial cell
Angiogenesis
Increase epithelial tissue in effect area
Prostaglandin :function of prostaglandin
1.Stimulation of mucus and bicarbonate
2.Increase blood flow of mucus
3.Inhibition of HCL secretion

•It is a gram negative bacteria
•It has Flagel and movement
•Live between mucus membrane and epithelial layer
Epidemiology :
1.Seen in every age but increase in old age
2.In poor country patient 90% infection take in child age
3.90% duodenal ulcer patient has H-Pylori
4.70% gastric ulcer patient has H-pylori
5.30% gastric ulcer due to NSAIDs

Poor economic condition
Low education level

Belong to two factors bacterial and host factors
Bacterial factors:
Pathogen virulence factor :vaculatingcytotoxin–A ( VaCA)
Cytotoxinassociated gen (Cag-A)
Urease : bacteria producing ammonia by urease enzyme

Pathogenesis and pathophysiology
Dr.mazullah zahid
21
Reaction of host abut H-pylori: increase supply of neutrophil ,
lymphocyte and macrophage to effected area
Increase level of cytokine in effected area : interleukin alpha and
beta , IL2 ,IL6 , TNF alpha and IL Gama
Active humoral reaction in human but not benefit
Reactive oxygen and nitrogen : this can damage epithelium
Host factors

oThis drugs can fined 10-20% gastric ulcer and 2-5% duodenal ulcer
oIncrease complication of ulcer
oApirinis the most common drugs
oThis drugs can inhibition of underling enzyme

2.Cyclooxgynase-2 ( macrophage , leukocyte , fibroblast , synovial )

Age above 60years
Past History of peptic ulcer
Past History of this drug side effect
Combine with corticosteroids and anti coagulant
High dose intake or combination of two NSAIDs
Sever internal disease
Increase with paroxicamand ketoprofen
Risk Factors that increase complication of NSAIDs
Dr.mazullah zahid
24
Factors can cause peptic ulcer
Increase in smoker people
Delayed repairing of ulcer
Destruction of treatment response
Increase complication of ulcer
Decrease duodenal bicarbonate secretion
Increase risk of H-pylori
Cigarette smoking
