What role do antibiotics play in managing asthma exacerbation?

From the Guidelines

Antibiotics are not recommended for the treatment of acute asthma exacerbations except as needed for comorbid conditions, such as bacterial infections like pneumonia or acute bronchitis 1.

Key Points to Consider

• The use of antibiotics in asthma exacerbation is generally reserved for cases with suspected bacterial infection, such as pneumonia or acute bronchitis 1.
• Routine use of antibiotics in asthma exacerbation without evidence of bacterial infection is not recommended, as it may contribute to antibiotic resistance and does not improve asthma outcomes 1.
• Some studies suggest that antibiotics may be considered in patients with asthma exacerbation and evidence of bacterial infection, but the evidence is limited and the decision should be made on a case-by-case basis 1.

Important Considerations

• The presence of fever and purulent sputum is not a reliable indicator of bacterial infection, and the decision to use antibiotics should be based on a thorough clinical evaluation 1.
• The use of antibiotics should be guided by the presence of comorbid conditions, such as bacterial infections, and not by the presence of asthma exacerbation alone 1.
• Antibiotics such as azithromycin or clarithromycin may be considered in patients with asthma exacerbation and evidence of bacterial infection, but the specific choice and duration of therapy should be individualized based on the patient's clinical presentation and medical history 1.

From the Research

Role of Antibiotics in Managing Asthma Exacerbation

• Antibiotics are sometimes prescribed for asthma exacerbations, but their use is not always supported by evidence of a bacterial infection 2.
• A study found that antibiotic treatment in acute exacerbation of asthma might lead to longer asthmatic symptoms, specifically in patients with pharyngeal Streptococcus pneumoniae colonization 3.
• The use of antibiotics in asthma exacerbations is generally not recommended unless there is clear evidence of a bacterial infection 2, 4.
• Some studies suggest that antibiotics may improve symptoms and peak expiratory flow rate (PEFR) in asthma exacerbations, but the evidence is limited and inconsistent 2.
• The optimal duration of antibiotic treatment for asthma exacerbations is uncertain, and there is a need for further research in this area 5.
• In severe asthma exacerbations, infectious agents such as viruses and bacteria can play a role, and empiric treatment with antibiotics such as ceftriaxone and azithromycin may be initiated until infection is excluded 6.

Key Findings

• Antibiotic treatment was associated with an extended duration of wheezing in patients with acute moderate exacerbation of asthma 3.
• Macrolide antibiotics may improve symptoms and PEFR in asthma exacerbations, but the evidence is limited 2.
• Shorter durations of antibiotics for COPD exacerbations do not seem to confer a higher risk of treatment failure but are associated with fewer adverse events 5.
• Viral agents such as human rhinovirus-C, respiratory syncytial virus, and influenza A are common triggers of severe asthma exacerbations 6.
