What are the management strategies for gastrointestinal symptoms associated with COVID-19?

Management Strategies for Gastrointestinal Symptoms in COVID-19

The management of gastrointestinal symptoms in COVID-19 patients should focus on symptom control, fluid and electrolyte balance, nutritional support, and monitoring for disease progression, while continuing appropriate COVID-19 therapies.

Incidence and Presentation of GI Symptoms

Gastrointestinal symptoms are common in COVID-19 patients, with:

• Diarrhea being the most prevalent GI symptom (8.6-23.1% of patients) 1
• Other symptoms include nausea/vomiting (4.3-10.3%), abdominal pain (8.8%), and anorexia 1, 2
• GI symptoms may precede respiratory symptoms by 1-2 days in some cases 1
• Rectal bleeding has been reported in 4-13.7% of COVID-19 patients 1

Assessment of GI Symptoms

When evaluating COVID-19 patients with GI symptoms:

1. Obtain a thorough history of GI symptoms including onset, characteristics, duration, and severity 1
2. For outpatients with new-onset diarrhea, assess for high-risk COVID-19 exposure and other COVID-19 symptoms 1
3. Monitor for electrolyte disturbances, particularly:
   • Hyponatremia
   • Hypokalemia
   • Hypocalcemia 3
4. Consider that patients with GI symptoms as initial presentation may have:
   • Longer duration of viral shedding
   • Longer hospitalization requirements
   • Lower lymphocyte counts
   • Higher inflammatory markers (procalcitonin, hs-CRP) 4

Management Strategies

1. Fluid and Electrolyte Management

• Closely monitor fluid status and electrolyte levels, particularly sodium, potassium, and calcium 3
• Provide appropriate fluid replacement based on clinical assessment
• Correct electrolyte abnormalities promptly as they may affect disease progression 5
• Pay special attention to fluid and electrolyte status in hospitalized and ICU patients 5

2. Nutritional Support

• Assess nutritional status early in hospitalization
• Energy requirements range from 15-30 kcal/kg/day 6
• Protein goals range from 1.2-2.0 g/kg/day 6
• Consider the following feeding approaches:
  • Oral nutrition when possible
  • Enteral nutrition for patients unable to meet nutritional needs orally
  • Parenteral nutrition only when enteral route is contraindicated 6
• For enteral nutrition, use ready-to-use formulas in continuous mode when possible 6
• Monitor for refeeding syndrome, particularly when initiating parenteral nutrition 6

3. Medication Management

• Consider budesonide (9 mg/day for 8 weeks) for patients with small bowel and ileo-cecal inflammation 1
• For inflammatory bowel disease patients with COVID-19:
  • Continue 5-aminosalicylic acid derivatives (mesalazine)
  • Consider optimizing oral 5-aminosalicylic acid dose with or without topical (rectal) 5-aminosalicylic acid for uncontrolled symptoms 1
  • Avoid non-steroidal anti-inflammatory drugs (NSAIDs) 1

4. Endoscopic Procedures

• Defer non-urgent endoscopic procedures during COVID-19 peaks 1
• Consider endoscopy only for:
  • Acute gastrointestinal bleeding
  • Symptomatic strictures requiring dilatation
  • Severe obstructive symptoms 1
• When endoscopy is necessary:
  • Prefer proctosigmoidoscopy over full colonoscopy when appropriate
  • Use proper PPE and infection control measures
  • Screen patients for COVID-19 symptoms before procedures 1

5. Remote Monitoring and Telehealth

• Implement remote monitoring of disease activity through virtual clinics 1
• Use telephone/email helplines for patient support 1
• Consider home-based fecal calprotectin testing when available 1
• Conduct clinical appointments by telephone or telemedicine when possible 1

Special Considerations

• Patients with GI symptoms may have worse outcomes and require closer monitoring 2
• Be aware of potential fecal-oral transmission; implement appropriate precautions 2
• For patients with inflammatory bowel disease:
  • Do not stop maintenance medications without consulting IBD specialists
  • Prevent disease flares as a priority to avoid hospitalization 1
  • Consider exclusive enteral nutrition for patients with flaring Crohn's disease 1

Pitfalls to Avoid

1. Failing to recognize that GI symptoms may be the initial presentation of COVID-19
2. Neglecting electrolyte monitoring in patients with significant diarrhea
3. Stopping IBD medications without specialist consultation
4. Performing unnecessary endoscopic procedures during high COVID-19 prevalence
5. Inadequate nutritional support for hospitalized patients

By implementing these management strategies, healthcare providers can effectively address gastrointestinal manifestations of COVID-19 while minimizing complications and optimizing patient outcomes.
