What is the recommended treatment for patients with severe gastritis requiring hospital admission?

Treatment of Severe Gastritis Requiring Hospital Admission

Patients with severe gastritis requiring hospital admission should be managed in a high dependency unit (HDU) or intensive care unit (ICU) setting with full monitoring and systems support, including intravenous fluids, proton pump inhibitors, and appropriate diagnostic workup.

Initial Assessment and Triage

When a patient presents with severe gastritis requiring hospitalization, a structured approach is essential:

1. Severity Assessment:

   • Evaluate for signs of hemodynamic instability (tachycardia, hypotension)
   • Assess for dehydration (dry mucous membranes, decreased skin turgor)
   • Check for signs of bleeding (hematemesis, melena, hematochezia)
   • Monitor vital signs frequently (pulse, blood pressure, respiratory rate, temperature)

2. Immediate Diagnostic Workup:

   • Complete blood count to assess for anemia and infection
   • Comprehensive metabolic panel to evaluate electrolyte abnormalities
   • Coagulation studies
   • Blood cultures if sepsis is suspected
   • Stool studies for blood, pathogens, C. difficile toxin 1

Hospital Setting and Monitoring

• Admit patients with severe gastritis to a high dependency unit or intensive care unit 1
• Ensure continuous monitoring with hourly vital signs
• Implement regular assessment of fluid balance
• Monitor for signs of deterioration or complications 1

Therapeutic Interventions

1. Fluid Resuscitation and Supportive Care

• Intravenous fluid therapy to correct dehydration and electrolyte imbalances
• Correction of coagulopathy if present
• Nutritional support as appropriate based on severity

2. Pharmacological Management

• Proton Pump Inhibitors (PPIs):

  • High-dose intravenous PPI therapy (e.g., pantoprazole or esomeprazole 80mg IV bolus followed by 8mg/hr infusion for 72 hours)
  • Continue until clinical improvement, then transition to oral therapy

• Antibiotics:

  • Indicated if infectious etiology is suspected
  • Broad-spectrum coverage initially, then targeted based on culture results
  • Essential for emphysematous gastritis or suspected bacterial infection 2, 3

3. Endoscopic Evaluation and Intervention

• Timing: Urgent endoscopy within 24 hours of admission for patients with suspected bleeding 1
• Setting: Endoscopy should be performed in a fully equipped endoscopy unit with trained staff 1
• Interventions:
  • Hemostatic therapy for active bleeding (thermal coagulation, injection therapy, or clips)
  • Biopsy for histopathological confirmation of gastritis type 1
  • Assessment for H. pylori infection 1

Management Based on Etiology

Helicobacter pylori-Associated Gastritis

• Confirm H. pylori infection through rapid urease test, histology, or stool antigen test 1
• Once stabilized, initiate eradication therapy:
  • Triple or quadruple therapy based on local resistance patterns
  • Confirm eradication after treatment 1

Autoimmune Gastritis

• Check antiparietal cell antibodies and anti-intrinsic factor antibodies
• Evaluate for vitamin B12 and iron deficiencies
• Consider screening for concomitant autoimmune disorders, particularly thyroid disease 1

Hemorrhagic Gastritis

• More aggressive management with continuous PPI infusion
• Consider transfusion if hemoglobin drops significantly
• Repeat endoscopy if bleeding persists despite medical therapy 2

Emphysematous Gastritis

• Requires aggressive antibiotic therapy and intensive care
• Surgical consultation for potential necrotic tissue debridement
• High mortality condition requiring prompt recognition and management 3

Discharge Planning and Follow-up

• Continue oral PPI therapy for 4-8 weeks after discharge
• Schedule follow-up endoscopy based on findings and severity:
  • For advanced atrophic gastritis, consider surveillance every 3 years 1
  • For autoimmune gastritis, individualized surveillance based on risk factors 1
• Educate patients about warning signs requiring immediate medical attention

Common Pitfalls and Caveats

• Failure to recognize severe disease: Patients with severe gastritis can deteriorate rapidly; early HDU/ICU admission is crucial
• Inadequate fluid resuscitation: Aggressive fluid replacement is essential, especially in hemorrhagic gastritis
• Delayed endoscopy: Prompt endoscopic evaluation is necessary to guide appropriate management
• Missing underlying causes: Always investigate for predisposing factors (medications, alcohol, autoimmune conditions)
• Overlooking nutritional deficiencies: Patients with atrophic gastritis require evaluation for vitamin B12 and iron deficiencies 1

By following this structured approach, clinicians can effectively manage patients with severe gastritis requiring hospital admission, reducing morbidity and mortality while improving outcomes.
