What are risks for acute gastritis?

A

NSAIDs: ASA, ibuprofen, naproxen

Alcohol, smoking, irradiation, chemo, sepsis, physical trauma

9
Q

Why are NSAIDs a risk factor for acute gastritis?

A

Inhibition of bicarbonate production

10
Q

What are the medications used to treat acute gastritis?

A

PPIs, hydrogen receptor antagonists

11
Q

How do the medications for acute gastritis work?

A

Decrease gastric activity

12
Q

What is the condition of aspirin toxicity?

A

Salicylism

13
Q

Is an acute peptic ulceration the same as a peptic ulcer?

A

NO

14
Q

What are the two causes of acute peptic ulcerations?

A

Severe physiologic stress

NSAIDs

15
Q

What is the recovery timeline for acute gastritis?

A

Heals within a few days to weeks

16
Q

Acute peptic ulceration can occur in patients with what neural condition and why?

A

Intracranial disease due to increased ICP (via vagal nerve hypothesis)

17
Q

Which is more severe: acute or chronic gastritis?

A

Acute gastritis

18
Q

Hematemesis is rare in which kind of gastritis: acute or chronic?

A

Chronic

19
Q

Which form of gastritis has upper abdominal “discomfort” and which has epigastric pain?

A

Acute - epigastric pain

Chronic - upper abdominal discomfort

20
Q

Chronic gastritis is associated with what other GI condition?

A

Peptic ulcers

21
Q

What are the two major complications associated with chronic gastritis?

A

Peptic ulcer disease

Gastric adenocarcinoma

22
Q

70-90% of chronic gastritis cases involve which pathogen?

A

Helicobacter pylori

23
Q

What are risk factors for chronic gastritis?

A

Poor childhood sanitation/hygiene

24
Q

What is unique about the symptoms of chronic gastritis?

A

Most commonly asymptomatic (although chronic)

25
Q

What are the effects of chronic gastritis on the body?

A

1 increased acid production

2 epithelial metaplasia leading to risk for gastric cancer

26
Q

Autoimmune gastritis most commonly affects what population?

A

Elderly females over 60 years of age

27
Q

What is autoimmune gastritis?

A

Gastric atrophy + chronic gastritis

28
Q

Autoimmune gastritis attacks what specific GI cells and can lead to what overlying condition?

A

Attack parietal cells; pernicious anemia

29
Q

What is pernicious anemia?

A

Difficulty producing RBC due to the inability to absorb vitamin B12 because of the loss of intrinsic factor

30
Q

What are the locations for peptic ulcer disease?

A

1 proximal duodenum

2 gastric antrum (distal stomach)

31
Q

What is the appearance associated with peptic ulcer disease?

A

Red granulation tissue as a solitary “punched-out” lesion and possible hemorrhage

32
Q

What is the gender bias associated with peptic ulcer disease?

A

Males

33
Q

Peptic ulcer disease is usually a result from what?

A

Chronic gastritis or hyperacidity

34
Q

What is the most common pathogen involved with peptic ulcer disease?

A

Helicobacter pylori

35
Q

Helicobacter pylori is present in what percent of PUD cases?

A

70-90%

36
Q

Will all cases of a Helicobacter pylori infection result in PUD?

A

NO (only 5-10%) but remember that the majority of PUD cases DO involve H. pylori

37
Q

How is smoking a risk factor for PUD?

A

Decreased GI blood flow

Decreased healing ability
