Combining Herbal and Western Medicine for Pertussis-Like Syndrome in Children

Persistent, spastic cough in pertussis-like syndrome (PLS) can be distressing for children and frustrating to manage in clinical practice. While macrolide antibiotics address underlying pathogens, they often fall short in alleviating symptoms. A new systematic review and meta-analysis examines whether integrating traditional herbal medicine (HM) with standard Western medicine (WM) can improve outcomes in pediatric PLS.

Why Look Beyond Antibiotics?

PLS presents similarly to pertussis but without confirmed Bordetella pertussis infection. In children, the prolonged cough disrupts sleep, feeding, and family routines. While macrolides like erythromycin or azithromycin are standard, they rarely shorten the paroxysmal phase or provide meaningful symptom relief.

Traditional herbal medicine has been used for centuries in East Asia for respiratory illnesses. This review explored whether combining HM with WM could enhance clinical outcomes in children with PLS.

What the Evidence Shows

The meta-analysis pooled data from 23 randomized controlled trials involving nearly 2,000 pediatric patients. Across studies, children receiving HM + WM compared to WM alone demonstrated:

• Faster normalization of blood routine parameters.

• Improved total effective rate, with greater symptom resolution.

• Shortened duration of spastic cough by approximately 3 days.

• Reduced hospitalization time by an average of 2–3 days.

Mild adverse events—mostly gastrointestinal—were less frequent in the combined therapy group than with WM alone.

Clinical Considerations

These findings suggest potential value in an integrative approach, especially for cases where persistent cough significantly impacts quality of life despite appropriate antibiotic therapy.

However, it’s important to interpret results with caution. All RCTs were conducted in China using diverse herbal formulations, and the quality of evidence ranged from moderate to very low. Standardization of HM protocols and inclusion of non-Asian populations are necessary before widespread adoption.

Takeaway for Practice

For pediatric clinicians, this review highlights a potential adjunct to conventional therapy when managing PLS. Combining HM with WM may accelerate symptom resolution and recovery without increasing adverse effects.

While more robust trials are needed, this research underscores the importance of exploring integrative strategies in pediatric respiratory care—especially in conditions where symptom burden remains high despite standard treatment.
