What are the strategies for managing chronic fatigue after mononucleosis?

Strategies for Managing Chronic Fatigue After Mononucleosis

Physical activity is the most effective intervention for managing chronic fatigue after mononucleosis, with a gradual increase in exercise being recommended as the first-line approach. 1

Assessment of Post-Mononucleosis Fatigue

Before implementing management strategies, it's important to evaluate:

• Fatigue onset, pattern, duration, and changes over time 1

• Presence of treatable contributing factors such as:

  • Sleep disturbances 1
  • Nutritional deficits 1
  • Emotional distress, anxiety, or depression 1, 2
  • Physical deconditioning 3
  • Medication side effects 1

• Laboratory evaluation may be warranted based on symptoms:

  • Complete blood count to assess for persistent anemia 1
  • Thyroid function tests to rule out endocrine dysfunction 1

Evidence-Based Management Strategies

Physical Activity Interventions

• Gradually increasing physical activity is strongly supported by evidence (category 1 recommendation) 1
• Begin with low-intensity activities and progressively increase duration and intensity 1, 3
• A moderate walking program can be effective and accessible for most patients 1
• Aim for 150 minutes of moderate aerobic exercise per week with 2-3 strength training sessions 1
• For significantly deconditioned patients, consider referral to a physical therapist 1

Psychosocial Interventions

• Cognitive behavioral therapy (CBT) has strong evidence (category 1) for reducing fatigue 1
• Mindfulness-based approaches can effectively reduce fatigue levels 1
• Psychoeducational interventions about fatigue management strategies are beneficial 1
• Addressing illness perceptions is important, as these are predictive of prolonged fatigue 4

Energy Conservation Strategies

• Teach patients to plan activities according to energy levels using a daily/weekly diary 1
• Prioritize essential activities and delegate less important tasks 1
• Schedule activities during peak energy periods 1
• Limit daytime naps to less than one hour to avoid disrupting nighttime sleep 1

Sleep Hygiene Improvements

• CBT for sleep is recommended (category 1) for post-infectious fatigue management 1
• Establish consistent sleep and wake times 1
• Create a restful sleep environment 1
• Avoid caffeine, alcohol, and electronic devices before bedtime 1

Special Considerations

• Female gender is a risk factor for developing chronic fatigue after mononucleosis 2, 5
• Pre-existing mood disorders increase risk of prolonged fatigue 2, 4
• Most adolescents recover with time (only 4% still meet criteria for chronic fatigue syndrome 24 months after mononucleosis) 5
• Steroid use during acute mononucleosis does not appear to increase risk of chronic fatigue 5
• Excessive bed rest during acute illness may prolong recovery; activity as tolerated is preferred 3

Monitoring and Follow-up

• Regular self-monitoring of fatigue levels using a diary can help document improvement 1
• Reassess fatigue levels at regular intervals to evaluate treatment effectiveness 1
• If fatigue persists despite interventions, consider referral to specialists 1
• Educate patients that recovery is typically gradual, with most seeing improvement over time 1, 5

Pharmacologic Options

• There is limited evidence for pharmacologic management of post-infectious fatigue 1
• Consider treating specific symptoms that may contribute to fatigue (e.g., short-term hypnotics for insomnia) 1
• Psychostimulants are not generally recommended for post-infectious fatigue without other indications 1
