Study Notes
Overview of GERD
- Gastroesophageal reflux disease (GERD) occurs due to gastric contents reaching the esophagus, causing both esophageal symptoms and extraesophageal issues.
- Extraesophageal symptoms include hoarseness, cough, wheezing, and asthma.
Risk Factors
- Established risk factors include increased body mass index (BMI), tobacco smoking, and genetic predisposition.
- Higher BMI correlates with a greater risk of GERD, with obesity significantly increasing susceptibility.
Esophagogastric Junction Dysfunction
- GERD is characterized by dysfunction at the esophagogastric junction, including ineffective lower esophageal sphincter function, increasing regurgitation of acidic contents.
- Normal transient lower esophageal sphincter relaxation can become problematic if prolonged or frequent.
Prevalence and Demographics
- In North America, GERD prevalence is around 15.4%, varying by age.
- Almost 50% of newborns experience regurgitation, resolving in 90% by age one, but prevalence increases again during adolescence and adulthood.
Symptoms
- Cardinal symptoms include heartburn and acid regurgitation, with chest pain being common.
- Atypical symptoms may include dysphagia, chronic cough, asthma exacerbations, and dental erosion.
Complications
- Esophagitis, affecting 18% to 25% of GERD patients, is the most common complication characterized by mucosal inflammation and erosions.
- Barrett esophagus is a concerning condition that can develop due to chronic GERD, leading to an increased risk of esophageal adenocarcinoma.
Treatment Guidelines
- Lifestyle modifications recommended: weight loss, smoking cessation, and elevation of the head of the bed.
- Proton pump inhibitors (PPIs) are the first-line treatment, more efficacious than histamine-2 receptor antagonists.
- Initial treatment involves once-daily PPI for 4-8 weeks, with a preference for the lowest effective maintenance dose thereafter.
- For inadequate response, consider twice-daily PPIs or histamine-2 receptor antagonists.
Clinical Recommendations
- Screening for Barrett esophagus is not routinely recommended but may be considered for high-risk individuals.
- Continuous PPI therapy is advisable for patients with Barrett esophagus to prevent progression to cancer.
Safety and Long-term Considerations
- Long-term PPI use may be linked to potential adverse effects, including kidney disease, infections, osteoporosis, and gastric cancer.
- PPIs are generally safe for pregnant patients.
Summary of Treatment Outcomes
- Effective PPI therapy typically alleviates GERD symptoms and aids in healing erosive esophagitis, with regular monitoring advised for long-term management.
GERD Overview
- Gastroesophageal reflux disease (GERD) occurs when gastric contents reflux into the esophagus.
- Symptoms can extend beyond the esophagus, affecting the pharynx, mouth, larynx, and airways, leading to hoarseness, wheezing, cough, and asthma.
Risk Factors
- Established risk factors include:
- Increased body mass index (BMI)
- Tobacco smoking
- Genetic predisposition
- Obesity is linked to a higher risk of developing GERD.
Esophagogastric Junction Dysfunction
- GERD involves dysfunction at the esophagogastric junction, specifically loss of lower esophageal sphincter (LES) function.
- Normal transient LES relaxation can lead to GERD if excessive.
Prevalence and Age-Related Trends
- GERD prevalence is age-dependent:
- Nearly 50% of newborns experience regurgitation, resolving in 90% by age 1.
- The prevalence rises again in adolescence and continues to increase in older adults.
Symptoms
- Cardinal symptoms include:
- Heartburn
- Acid regurgitation
- Common chest pain
- Atypical symptoms may include:
- Dysphagia
- Chronic cough
- Asthma
- Chronic laryngitis
- Hoarseness
Complications
- Esophagitis (inflammation of the esophagus) occurs in 18% to 25% of GERD patients, detectable via endoscopy and classified by the Los Angeles system.
- Barrett esophagus, a precursor to esophageal adenocarcinoma, can develop as a result of GERD.
Treatment Guidelines
- General recommendations include:
- Weight loss for overweight or obese individuals.
- Elevating the head of the bed for certain patients.
- Lifestyle modifications, including healthy eating and smoking cessation.
- Proton pump inhibitors (PPIs) are the most effective treatment, outperforming histamine2 receptor antagonists and placebo.
- Initial PPI therapy should last for 4 to 8 weeks, with adjustments based on patient response.
- If patients do not respond to PPIs, further evaluation with pH and impedance monitoring may be necessary.
Pharmacologic Management
- PPIs work by irreversibly inhibiting hydrogen-potassium ATPase, reducing stomach acidity and alleviating GERD symptoms.
- Current clinical guidelines suggest an initial standard-dose PPI for those with typical symptoms for 4 weeks, with prolonged therapy if endoscopy-verified erosive esophagitis is present.
Atypical Presentations and Emerging Concerns
- GERD patients may exhibit atypical presenting symptoms, including:
- Dyspepsia
- Nausea
- Bloating
- Belching
- Long-term PPI treatment may be associated with potential adverse events, such as kidney disease, infections, osteoporosis, and gastric cancer concerns.
