Study Notes
Gastro-Oesophageal Reflux Disease (GORD)
- Commonly caused by defective lower oesophageal sphincter (LES) function.
- Symptoms include heartburn and regurgitation.
- Obesity and pregnancy are significant lifestyle risk factors.
Treatment Options for GORD
- Proton Pump Inhibitors (PPIs) are the main drug class for acid suppression.
- Antacids provide immediate relief for mild GORD symptoms.
- Dietary factors like garlic, onions, chocolate, and fatty meals can relax the LES and aggravate GORD.
Complications and Management
- Untreated GORD can lead to Barrett's oesophagus and oesophageal carcinoma.
- Elevating the head of the bed is recommended for patients with nocturnal GORD symptoms.
Peptic Ulcer Disease (PUD)
- Helicobacter pylori is the primary bacterium associated with PUD.
- Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) inhibit prostaglandin synthesis, impairing mucosal defense and contributing to ulcer formation.
- Common symptom includes sharp, gnawing epigastric pain after meals.
Pharmacological Treatments for PUD
- Triple therapy for H. pylori-induced PUD consists of a PPI, amoxicillin, and clarithromycin.
- Proton Pump Inhibitors are first-line for NSAID-induced ulcers.
- Misoprostol increases mucosal protection by stimulating prostaglandin production.
Adverse Effects of Treatments
- Long-term use of PPIs can lead to hypomagnesemia and fractures as serious side effects.
- Common side effects of PPIs include headache, nausea, and diarrhea.
- Long-term NSAID use may result in gastric ulcers due to reduced prostaglandin levels.
Testing and Additional Treatments
- The urea breath test is used to confirm H. pylori infection in PUD patients.
- Alginate forms a protective barrier that prevents reflux in GORD management.
- H2 Receptor Antagonists (H2RAs) block gastric acid secretion by targeting H2 receptors on parietal cells.
Gastroesophageal Reflux Disease (GORD) Risks and Symptoms
- Common risk factors for GORD include obesity, smoking, and hiatus hernia; a high-protein diet is not a common risk factor.
- Garlic is known to relax the lower oesophageal sphincter (LES) and can exacerbate GORD symptoms.
- Alarm symptom requiring immediate investigation is dysphagia, while heartburn and regurgitation are typical symptoms of GORD.
Treatment and Pharmacology
- Proton Pump Inhibitors (PPIs) are considered the first-line treatment for moderate-to-severe GORD.
- Nitrates can decrease LES tone and may worsen GORD symptoms.
- Long-term PPI therapy can lead to Clostridium difficile infection as a potential adverse effect.
H. pylori Infection and Diagnosis
- H. pylori infection increases the risk of gastric ulcers and gastric carcinoma.
- The urea breath test for H. pylori detects carbon dioxide as a key indicator.
- A first-line pharmacological regimen for eradicating H. pylori typically includes clarithromycin, amoxicillin, and esomeprazole.
Peptic Ulcer Disease (PUD) and Medications
- NSAID-induced peptic ulcers occur due to inhibition of cyclo-oxygenase-1 (COX-1).
- Commonly used mucosal protective agents for NSAID-induced ulcers include misoprostol and sucralfate.
- Various PPIs, including omeprazole, pantoprazole, and esomeprazole, inhibit CYP2C19 and decrease the effectiveness of clopidogrel.
Symptoms and Lifestyle Modifications
- The most common presenting symptom of peptic ulcer disease is gnawing or burning pain after meals.
- Selective serotonin reuptake inhibitors (SSRIs) increase the risk of gastrointestinal bleeding when combined with NSAIDs.
- Elevating the head of the bed is the most effective lifestyle modification for reducing nocturnal GORD symptoms.
