2.2. Gastric Disease - Gastritis Flashcards
Is Gastritis more common in Males or Females?
Males
What are the 3 methods Gastritis can be a result of?
A - Autoimmune Disease
B - Bacterial Infection
C - Chemical Toxicity
What is the pathology of Autoimmune Gastritis?
Autoantibodies react with the Gastric Mucosa causing inflammation
What is the pathology of Bacterial Infection Gastritis?
A bacterial reaction causes an Immune Mediated Inflammatory Response
(This is usually H. Pylori)
What is the pathology of Chemical Toxicity Gastritis?
Toxic Chemicals irratating the Gastric Mucosa, causing inflammation
What are the 3 areas where Gastritis can occur?
- The Antrum of the Stomach
- The Corpus of the Stomach
- A Mix of Both
What will Gastritis in the Antrum of the Stomach cause?
An increase in Gastric Acid Production
What can an increase in Gastric Acid production lead to?
- Peptic Ulceration (Common)
2. Gastric Cancer (Low Risk)
What will Gastritis in the Corpus of the Stomach cause?
A decrease in Gastric Acid Production
What can a decrease in Gastric Acid production lead to?
Gastric Atrophy
What can Gastric Atrophy lead to?
Gastric Cancer
What will a Mix of Antral and Corpusal Gastritis cause?
No change in the acid levels, so there will be no significant disease
What are the Clinical Signs of Antral Gastritis?
- Increased Gastric Acid
- Symptoms of Gastro-Oesophageal Reflux Disease (GORD)
- Peptic Ulceration
What are the Clinical Signs of Corpusal Gastritis?
- Decreased Gastric Acid
- A Decrease in Interleukin-1 (IL-1)
- A Decrease in Tumour Necrosis Factor (TNF)
- Gastric Cancer
Why is there a decrease in Interleukin-1 (IL-1)?
There is no known reason
Why is there a Decrease in Tumour Necrosis Factor (TNF)?
Due to the Decrease in Interleukin-1 (IL-1)
Why is there an increased chance in getting Gastric Cancer?
Due to the Decrease in Tumour Necrosis Factor (TNF)?
What would a patient with Gastritis present with?
- Epigastric Pain
- Nausea / Vomiting
- Heartburn
- Night Umbilical Pain
Why would the Epigastric Pain occur?
Due to the Inflammation in the Stomach
Why does the Nausea / Vomiting occur?
Due to the inflammation in the stomach and the bodies natural reaction to Stomach irritation
Why does the Heartburn occur in Antral Gastritis?
Due to the Excess of Gastric Acid produced leading to GORD symptoms
Why does the Heartburn occur in Corpusal Gastritis?
Due to the inflammation in the Stomach
Why would Night Umbilical Pain occur?
Due to the potential pain caused by a Duodenal Ulcer - it will be worse when lying down (i.e. at night)
What investigations are necessary for Gastritis?
- Upper G.I. Endoscopy with Biopsy
2. The Investigations for H. Pylori infection
What are the investigations for H. Pylori infection?
- Serology
- Stool ELISA
- Bacterial Culture
- Urea Breath Test
What is the purpose of the Upper G.I. Endoscopy with Biopsy?
- To visualize where the Gastritis is, and its severity
2. To see if any Dysplasia has occurred
What is the Treatment for Gastritis?
- Eradication Therapy (if H. Pylori is the cause)
2. Lifestyle Altercation (Cease chemical ingestion if that is the cause)
What can occur due to the Inflammation?
Bleeding into the Gastric Lumen
