Peptic ulcer disease
1. Peptic Ulcer disease
A peptic ulcer is a defect in the gastric or
duodenal wall that extends through the
muscularis mucosa (the lowermost limit of the
mucosa) into the deeper layers of the wall
(submucosa or the muscularis propria )
American Society for Gastrointestinal Endoscopy GUIDELINE 2010
Spechler SJ. Peptic ulcer disease and its complications 2002.
2. • Ulkus peptikum adalah keadaan terputusnya
kontinuitas mukosa yang meluas di bawah epitel
atau kerusakan pada jaringan mukosa,submukosa
hingga lapisan muskularis mukosa dengan garis
tengah lebih atau sama dengan 5 mm dari suatu
daerah saluran cerna atas yang langsung
berhubungan dengan cairan asam
lambung/pepsin
• Erosi adalah kerusakan jaringan yang hanya
terbatas pada lapisan mukosa.
3. Peptic ulcer disease as an infectious disease caused by
H pylori infection, or a side effect of NSAID use has almost
eliminated elective surgery for peptic ulcer disease.
Complications of peptic ulcer disease, either
bleeding or perforation, still frequently require surgical
intervention.
Bleeding peptic ulcers can usually be treated with
nonsurgical means, 5% to 10% will require emergent
surgery for hemostasis
4. THE EPIDEMIOLOGY OF PEPTIC ULCER
DISEASE (PUD )
• in the 21st century peptic ulcer disease is predominantly a disease of
the elderly.
• a marked decline in the incidence of all peptic
ulcer disease, with declines in ulcer hospitalization rates of 40% to 50%
over the past 3 decades
• Duodenal ulcer is more common than gastric ulcer , but decreasing
significantly
• The rate of ulcer complications and the need for emergent ulcer surgery
may have increased slightly over the past 30 years

7. Peptic Ulcer disease
Common causes
• Helicobacter pylori ( Hp) infection
• NSAIDs , Antiplatelet Aspirin low dose ,Clopidogrel or
combination
• Non Hp, Non NSAIDs
10. Need for Aspirin/NSAIDs & Risks
Aspirin, like all NSAIDs,
injures the gut by
causing topical injury to
the mucosa and by
systemic effects induced
by prostaglandin
depletion.1
L-ASA (75-325 mg per
day) was associated with
a 2- to 4-fold increase of
the risk for upper
gastrointestinal (GI)
events.2

11. Risk factors for L-ASA-induced GI injury
J Am Coll Cardiol. 2008 Oct 28;52(18):1502–1517.
• A high aspirin dose
• History of peptic ulcer or ulcer complication
• Use of NSAIDs
• Advanced age
• Concurrent use of anticoagulants
• Presence of severe disease
• Antiplatelet therapy
12. Need for Antiplatelet Therapy & Risks
Antiplatelet therapy
- primary and
secondary
treatment strategies
for cardiovascular
disease.

Gastrointestinal (GI) complications
such as ulceration and related
bleeding.
13. Risks with Antiplatelet Therapy
ADP receptor antagonists impair the healing of gastric ulcers by
inhibiting platelet release of pro-angiogenic growth factors.
This may then, in the presence of acid, lead to clinically significant
ulceration and related complications.

19. Characteristics of Gastroduodenal Ulcers
During Treatment with LDA/NSAIDs
1. Higher prevalence of bleeding
complication
2. multiple ulcers
3. Smaller in diameter
4. More frequently found in the
gastric antrum
5. less symptomatic

20. Role of Acid Suppression Agent
• Pharmacological agents that suppress acid secretion are
widely considered the standard of care for the prevention
of ulcer re-bleeding after initial endoscopic hemostasis in
ulcer with high risk stigmata (those with active bleeding,
non bleeding visible vessel and possibly adherent clot)1-5
• The therapeutic goal in these patients is to achieve an
intragastric pH>6, a point at which the clotting process is
optimized and any formed clot is stabilized1,6-7

30. Goals of treatment in PUD
pain relief and resolution of symptoms
mucosal healing
prevention of recurrence and complications.
31. Management Strategy in PUD
• H Pylori testing in all patients with PUD, follow by eradication therapy
• PPI is the most effective treatment for gastric Ulcer ( 8 weeks), and Duodenal Ulcer (
4 weeks )
• Endoscopy :
Endoscopy accurate for diagnose and prognose of PUD , and an effective treatment for
bleeding Ulcer
• Duodenal ulcers are extremely unlikely to be malignant, and routine biopsy is not recommended
• Gastric ulcers should undergo biopsy because malignant gastric ulcers may appear
endoscopically benign
• Refractory PUD, suggested for surveillance endoscopy until the ulcer has healed or the etiology
has been defined
• Endoscopy is an effective tool in the diagnosis,prognostication, and therapy of bleeding peptic
ulcers, recommended early in the course of hospitalization
• Rebleeding after initial endoscopic hemostasis, repeat endoscopic therapy is recommended
before considering surgical or radiologic intervention
• Endoscopy is not recommended in patients with clinical evidence of acute perforation
• endoscopy is recommended for the evaluation of gastric outlet obstruction

Eradication
Lansoprazole significantly reduced
the cumulative relapse of
symptomatic and complicated
ulcers in patients requiring NSAIDs
after eradication of H. pylori.
Significantly fewer patients (1/22,
4.5%) in the lansoprazole group
compared with the group that
received H. pylori eradication alone
(9/21, 42.8%) developed
recurrence of symptomatic and

36. PPIs and Drug Interactions
SC-FM-T3
The need of Anti platelet drugs Clopidogrel,
single or in combination with Low dose aspirin
to prevent cardiovascular is increasing, with
significant risk of serious Gastrointestinal
bleeding raise the current issue of PPI drug
interaction
37. Clopidogrel Bisulfate
Use and Metabolism
• Description
– In the US, about 23.4 million patients were receiving clopidogrel therapy during
the 12-month period before May 11, 20111
– Clopidogrel is a dose-dependent inhibitor of platelet activation and aggregation
– Selectively binds to the P2Y12 class of ADP receptors on platelets
– Pro-drug metabolized by CYP450 enzymes, principally 2C19, in the liver to
active metabolite
• Indications
– Acute coronary syndrome
– Recent MI, recent stroke, or established peripheral arterial disease
– Also used following percutaneous coronary intervention (PCI) and other vascular
interventions to reduce stent thrombosis3

↓ Active metabolites
CYP2C19
• CYP2C19, CYP3A4, and CYP2C9 play major roles in the metabolism of PPIs
• Competition for metabolism through CYP2C19 is a theoretical
mechanism by which clopidogrel antiplatelet action can be
attenuated by concurrent PPI use
39. Risk of GI Bleeding in Patients Receiving
Clopidogrel Therapy
• Major side effect – GI bleeding
• Incidence rate 2% in patients on clopidogrel1
• Clopidogrel does not directly cause gastric injury2
• May impair healing of existing gastric erosions due to its antiplatelet effect and exacerbate GI
complications from:
– Concomitant administration of aspirin and NSAIDs
– H. pylori infection
• Established correlation between major bleeding with subsequent MI, stroke and death2
• Concomitant administration of clopidogrel and PPI
– Prevalence of co-administration of Clopidogrel with PPI in the US is
31%–64%2
– Concomitant PPI administration reduces incidence of GI bleeding
compared to clopidogrel alone (RR: 0.19)3

PPI reduces risk of adverse GI events

41. Interaction Persists in Omeprazole Despite

lansoprazole
• Concomitant administration of lansoprazole and clopidogrel in
healthy subjects had no clinically important effect on exposure to
the active metabolite of clopidogrel or clopidogrel-induced platelet
inhibition
• No dose adjustment of clopidogrel is necessary when administered
with an approved dose of lansoprazole

• Omeprazole and esomeprazole reduce the antiplatelet activity of
clopidigrel
• Dexlansoprazole, lansoprazole and pantoprazole had less effect on
the antiplatelet activity of clopidigrel than did omeprazole or
esomeprazole
45. Summary
• PUD is one of the significant clinical problem for UGI diseases in
clinical practice.
• PUD as an infectious diseases is curable by H.pylori eradication
with a low recurrence rate
• NSAIDs , antiplatelet , low dose aspirin is now an increasing
factors for peptic ulcer etiology
• Anti acid supression drugs PPI is the most effective medical
treatment for PUD and ints complication
• Lansoprazole is one of the most effective PPI for the treatment for
symptoms and healing of PUD and its complication
