# Loeys‐Dietz Syndrome and Asthma: Pathophysiological Insights and Clinical Dilemmas

## TL;DR

This paper presents a case of severe asthma in a young adult with Loeys-Dietz syndrome, emphasizing the need for early recognition and tailored treatment to prevent life-threatening complications.

## Contribution

The paper highlights the under-recognized severity of asthma in Loeys-Dietz syndrome and the clinical challenges in managing it.

## Key findings

- Asthma in Loeys-Dietz syndrome can be severe and life-threatening, requiring careful management.
- Delayed treatment and inappropriate use of beta-blockers can worsen outcomes in these patients.
- Early intervention and preventive strategies are essential to avoid catastrophic respiratory events.

## Abstract

A 23‐year‐old man presented with a life‐threatening asthma exacerbation following a respiratory infection. Although he had a childhood history of asthma, he had remained asymptomatic in adulthood and reported regular use of both vapes and marijuana. His medical history included Type 2 Loeys‐Dietz syndrome (LDS), requiring multiple vascular surgeries, rendering standard asthma therapies relatively contraindicated. Due to the severity of his condition, nebulised beta‐agonists were cautiously administered, and his beta‐blocker therapy was substituted. Imaging and forced oscillation technique (FOT) demonstrated severe obstructive airways disease. Marked and persistent eosinophilia was noted. While asthma is a recognised comorbidity in LDS, earlier recognition and intervention, such as inhaled corticosteroids, smoking cessation support, and judicious use of beta‐blockers, may have reduced the severity. Increased awareness of the prevalence and severity of asthma in LDS could support earlier diagnosis, preventive strategies and timely escalation of therapy, thereby reducing the risk of catastrophic respiratory events.

We present a case of acute severe asthma in a young adult with Loeys‐Dietz syndrome, complicated by cardiovascular comorbidities. This case highlights the high prevalence and severity of asthma in LDS, the risks of delayed treatment and the importance of balancing bronchodilator therapy against vascular complications. Early recognition and preventive strategies are crucial to avoid life‐threatening deterioration in this population.
