The immune system’s response to two childhood respiratory diseases has been improved by researchers, leading to potential better treatments. The study, conducted by Murdoch Children’s Research Institute (MCRI) and published in Mucosal Immunology, discovered that suppurative lung disease and wheezing have similar inflammatory profiles despite their different symptoms. Dr. Melanie Neeland of MCRI stated that this breakthrough could lead to advancements in treatment.The study discovered that suppurative lung disease and wheezing were common in children, but the underlying mechanisms were not well understood. This led to limited treatment options and frequent disease recurrence. The research involved 93 children who had samples of lung fluid and blood taken at The Royal Children’s Hospital. It identified two treatable subtypes of the disease that were similar in frequency and immune signature across both respiratory diseases. Dr. Neeland stated that this discovery could potentially change clinical management if validated in future studies.The discovery represents a significant advancement in our comprehension of lung inflammation in children with wheezing and suppurative lung disease,” she remarked. “We have demonstrated that despite the distinct clinical manifestations of these two illnesses, similar inflammatory profiles are present in the lungs, suggesting that the same anti-inflammatory treatments could be beneficial for both.”
“Crucially, around 50% of children in each disease category exhibited a hyper-inflammatory reaction that may be treatable with treatments already authorized for use in children.
Utilizing anti-inflammatory treatments, such as repurposing asthma biologic medication, may present a new therapeutic approach for treating both conditions.
Preschool asthma/recurrent wheeze is a major cause of hospital admissions in children and can lead to long-term lung function issues. Suppurative lung diseases encompass various chronic lung conditions characterized by persistent cough, airway obstruction, and long-term health complications.
According to MCRI Dr. Shivanthan Shanthikumar, children with chronic respiratory diseases have not seen the same advancements in care as adults with similar conditions.
“Currently, the management of these conditions in children is lacking.According to the study’s lead author, “There is a critical need for new treatments for chronic respiratory diseases, especially for chronic cough, which is often treated with prolonged antibiotic use despite evidence of their limited effectiveness.” This overuse of antibiotics for a common condition is concerning due to the growing problem of antimicrobial resistance.
The lead author also stated, “However, we believe that by identifying and targeting the inflammatory profiles that contribute to these serious health conditions, we can improve the management of chronic respiratory diseases.” The research involved collaboration between the University of Melbourne and The Royal Children’s Hospital.
