Treatment for a 1-Year-Old Child with Cough, Fever, and Elevated CRP

Amoxicillin (90 mg/kg/day in 2 doses) is the first-line treatment for a 1-year-old child with cough, fever, and elevated CRP of 156, as this presentation strongly suggests bacterial pneumonia requiring immediate antibiotic therapy. 1, 2

Assessment of Severity

The child's presentation requires careful evaluation:

  • Fever and cough in a 1-year-old child
  • Significantly elevated CRP (156 mg/L) strongly suggests bacterial infection 3
  • Age under 2 years is a risk factor for severe disease 2

Treatment Algorithm

First-Line Antibiotic Therapy:

  • Amoxicillin oral: 90 mg/kg/day divided in 2 doses 1, 2
    • High-dose regimen is appropriate due to:
      • Age under 2 years
      • Significantly elevated CRP (>40 mg/L strongly suggests bacterial infection) 3
      • Risk of resistant pneumococcal strains

Alternative Options (if penicillin allergy or treatment failure):

  • Amoxicillin-clavulanate: 90 mg/kg/day of amoxicillin component divided in 2 doses 2, 4
  • Azithromycin: 10 mg/kg on day 1, followed by 5 mg/kg/day once daily for days 2-5 (if atypical pneumonia is suspected) 1, 5

Supportive Care:

  • Antipyretics (paracetamol or ibuprofen) for fever management 1
  • Ensure adequate hydration 1, 2
  • Monitor respiratory status (respiratory rate, work of breathing, oxygen saturation) 2

Hospitalization Criteria

Consider hospitalization if any of the following are present:

  • Respiratory rate >50 breaths/min 2
  • Oxygen saturation <92% or signs of respiratory distress 2
  • Inability to tolerate oral medications or fluids 2
  • Significant dehydration 2
  • Lack of reliable caregivers for home monitoring 2

Monitoring and Follow-up

  • Clinical reassessment within 48-72 hours is essential 2

  • Signs of improvement should include:

    • Decreased respiratory rate
    • Reduced work of breathing
    • Decreased fever
    • Improved feeding 2
  • If no improvement after 48 hours of antibiotic treatment:

    • Consider switching to second-line antibiotic (amoxicillin-clavulanate) 2
    • Re-evaluate for complications or alternative diagnosis 1

Treatment Duration

  • For uncomplicated bacterial pneumonia: 5-7 days 2
  • For more severe cases: 10 days 2
  • Continue treatment for at least 48-72 hours after resolution of symptoms 2

Important Considerations

  • The markedly elevated CRP (156) strongly suggests bacterial infection, as viral infections typically cause CRP values <40 mg/L 3
  • While CRP >40 mg/L has 88% specificity for bacterial infection, it doesn't definitively rule out viral causes 3
  • Antibiotic overuse is common in pediatric respiratory infections, but the high CRP value in this case justifies antibiotic therapy 6
  • Twice-daily dosing of amoxicillin has been shown to be as effective as three-times-daily dosing, which may improve adherence 2

Warning Signs for Immediate Medical Attention

Instruct parents to seek immediate medical attention if the child develops:

  • Increased work of breathing or respiratory distress
  • Persistent high fever despite antipyretics
  • Decreased oral intake or signs of dehydration
  • Lethargy or decreased responsiveness 1
