What is the assessment and management of a patient with nasal discharge of white secretion, productive cough of greenish sputum, and fever (hyperthermia) for 1 week with a maximum temperature of 39°C?

Assessment and Management of Acute Respiratory Tract Infection with Fever, Productive Cough, and Nasal Discharge

Clinical Assessment

This patient presents with features suggesting acute bacterial rhinosinusitis with lower respiratory tract involvement, warranting antibiotic therapy given the high fever (39°C) persisting for 1 week with purulent sputum production. 1

Key Diagnostic Features Present:

• High fever >39°C for 1 week - strongly suggests bacterial infection rather than viral etiology 1, 2
• Greenish (purulent) sputum - indicates bacterial involvement of lower respiratory tract 1
• White nasal discharge - suggests concurrent upper respiratory involvement 1
• Duration of 1 week - fever persisting >3 days indicates bacterial superinfection 1, 2

Immediate Clinical Evaluation Required:

• Chest examination for focal signs - crackles, bronchial breathing, or dullness suggest pneumonia requiring different management 1
• Respiratory rate and oxygen saturation - tachypnea or hypoxemia indicates severe disease requiring hospitalization 1
• Presence of dyspnea - suggests lower respiratory tract involvement beyond simple bronchitis 1

Diagnostic Workup

Outpatient Setting:

• No routine investigations needed if patient appears well without focal chest signs 1
• Chest radiograph indicated if focal chest signs present, severe dyspnea, or suspicion of pneumonia 1
• Sputum examination not routinely recommended unless pneumonia suspected or patient has risk factors 1

Indications for Hospital Admission:

• Severe respiratory distress, hypoxemia, or hemodynamic instability 1
• Focal chest signs with high fever suggesting pneumonia 1
• Failure to respond to outpatient therapy within 48-72 hours 3

Antibiotic Management

First-Line Treatment:

Amoxicillin-clavulanate is the recommended first-line antibiotic for this presentation combining features of bacterial rhinosinusitis (fever >39°C with purulent discharge) and productive cough with purulent sputum. 1, 3

Rationale for amoxicillin-clavulanate:

• Covers the most common pathogens: Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis 1
• Addresses beta-lactamase-producing organisms that may be present with purulent secretions 1
• Effective for both upper and lower respiratory tract bacterial infections 3

Dosing and Duration:

• Standard adult dose: 875 mg/125 mg twice daily or 500 mg/125 mg three times daily 3
• Treatment duration: 5-7 days for lower respiratory tract infection 1
• Duration for rhinosinusitis component: 7-10 days 3
• Recommend 7-10 days total given combined upper and lower tract involvement 1, 3

Alternative Antibiotics (if amoxicillin-clavulanate contraindicated):

For penicillin allergy:

• Respiratory fluoroquinolone (levofloxacin 750 mg daily or moxifloxacin 400 mg daily) 1, 3, 4
• Doxycycline 100 mg twice daily 1, 3

For treatment failure or frequent recent antibiotic use:

• Respiratory fluoroquinolone as above 1, 3
• Second or third-generation cephalosporins (cefuroxime-axetil, cefpodoxime-proxetil) 1, 3

Important Caveat - When NOT to Use Certain Antibiotics:

• First-generation cephalosporins (cephalexin) are NOT appropriate for respiratory tract infections due to inadequate coverage of S. pneumoniae 3
• Macrolides alone should be reserved for atypical pathogens (Mycoplasma, Chlamydia) or young adults during epidemics 1
• Azithromycin has activity but is not first-line given resistance concerns 5

Supportive Care

Symptomatic Management:

• Antipyretics (acetaminophen or NSAIDs) for fever control 2
• Analgesics for associated pain 2
• Intranasal saline irrigation to improve nasal drainage 3
• Adequate hydration and rest 2

Adjunctive Therapies:

• Intranasal corticosteroids may provide additional symptom relief for rhinosinusitis component 3
• Avoid cough suppressants - productive cough should not be suppressed as it aids clearance 1, 2

Follow-Up and Reassessment

Expected Response Timeline:

• Fever should resolve within 24-48 hours for pneumococcal infections, 2-4 days for other bacteria 3
• Clinical improvement expected within 48-72 hours of antibiotic initiation 1, 3
• Cough may persist beyond antibiotic course and should not be sole indicator of treatment failure 1

Reassessment Criteria:

• Return immediately if: worsening dyspnea, chest pain, hemoptysis, or altered mental status 1
• Return at 48-72 hours if: no fever reduction or clinical improvement 3
• Consider treatment failure if: no improvement after 3 days of appropriate antibiotics 1, 3

Management of Treatment Failure:

• Obtain chest radiograph if not already done 1
• Consider sputum culture and blood cultures 1
• Switch to respiratory fluoroquinolone if initially treated with beta-lactam 1, 3
• Consider hospitalization for IV antibiotics if severe or progressive disease 1

Common Pitfalls to Avoid

• Do not assume this is viral bronchitis - the combination of high fever for 1 week plus purulent sputum indicates bacterial infection 1, 2
• Do not withhold antibiotics - fever >38°C persisting >3 days strongly suggests bacterial infection requiring treatment 1, 2
• Do not use first-generation cephalosporins - inadequate respiratory pathogen coverage 3
• Do not rely on cough resolution as marker of cure - cough commonly persists after bacterial eradication 1
