A group of medical experts announced on Mar. 26 the publication of new standardized guidelines for diagnosing and managing recurrent wheezing in infants and toddlers. The recommendations were developed by the Committee of Pediatrics, China Medical Education Association, with contributions from specialists in pediatric respiratory medicine and allergology.
The guidelines aim to address challenges faced by clinicians due to the multifactorial causes of recurrent wheezing, which has made its diagnosis and treatment difficult in children under five years old. Until now, there have been no evidence-based clinical protocols available for pediatricians treating this condition.
Led by Professor Kunling Shen from the National Center for Children's Health in Beijing and Professor Yunxiao Shang from Shengjing Hospital of China Medical University, the expert panel established definitions to standardize care. Recurrent wheezing is defined as three or more episodes separated by at least seven days without symptoms, while infants and toddlers are classified as those aged between 29 days to three years. The guidelines also provide categories based on symptom manifestation, immunological response, age of onset, and severity.
"Evidence-based guidelines are critical to effectively manage diseases, especially those with multifactorial etiologies, such as recurrent wheezing. The establishment of guidelines can aid pediatricians in uniformly implementing therapeutic and preventive strategies and consequently improving the clinical outcomes of patients," Shen said.
Diagnostic recommendations include a thorough clinical history review and physical examination followed by laboratory tests like eosinophil counts, allergen testing, chest imaging, pulmonary function tests, and analysis of fractional exhaled nitric oxide. Testing for viral pathogens such as respiratory syncytial virus is strongly recommended along with bacterial infection screening when necessary. Additional ancillary investigations may include esophageal pH testing or genetic analysis.
Management strategies outlined involve assessment for type 2 inflammatory disease factors as well as environmental or nutritional contributors; long-term follow-up plans are encouraged. The guideline follows an "Evaluation-Diagnosis-Treatment-Re-evaluation-Re-diagnosis" approach but notes only weak support for using immunomodulators or other prophylactic agents like vitamin D or probiotics. Shang said: "The lack of standard guidelines for managing recurrent wheezing in infants and toddlers has resulted in inconsistent implementation of therapeutic and preventive strategies, leading to poor quality of life. The guidelines developed by us can provide a framework for improving the management of recurrent wheezing in infants and toddlers worldwide."
