May 2026 Research Update

This month, the new evidence was a single case showing how relapsing polychondritis can affect the windpipe and breathing tubes in a way that first looks like common asthma. The report described symptoms like wheezing and breathlessness, but the underlying problem was airway collapse (tracheobronchomalacia), which needed targeted testing to identify. The main message is that persistent or unusual breathing symptoms in relapsing polychondritis may sometimes reflect airway structure problems rather than airway irritation alone. [1]

In this patient, a CT scan of the chest and a bronchoscopy (a camera test into the airways) were used to confirm tracheobronchomalacia and airway changes consistent with relapsing polychondritis. After diagnosis, care escalated over time from corticosteroids and nighttime non-invasive ventilation to immune-targeting medicines (infliximab, then rituximab with IVIG). The report also described airway-focused procedures, including endobronchial stenting and argon laser therapy, reflecting that airway involvement can require both immune treatment and mechanical airway support. [1]

For patients and caregivers, this report mainly adds understanding rather than changing anything immediately, because it is one person and does not show how often this happens. It helps clarify that when relapsing polychondritis involves the airways, symptoms can resemble asthma and may not be explained by routine breathing treatments alone. It also shows that confirming airway involvement may require specialized tests like chest imaging and bronchoscopy, and that management in severe airway cases can involve a mix of breathing support, immune-suppressing medicines, and airway procedures. What remains uncertain is which patients are most likely to develop this kind of airway collapse and which approaches work best across larger groups. [1]
