Insights
Elevated von Willebrand factor levels in children with recurrent wheezing indicate endothelial dysfunction. Persistent high levels suggest chronic inflammation, potentially signifying the development of asthma.
Area of Science:
- Pediatric Pulmonology
- Vascular Biology
- Inflammation Research
Background:
- Recurrent wheezing and asthma are common in children.
- Understanding the underlying inflammatory processes is crucial for effective management.
- Endothelial dysfunction may play a role in the pathogenesis of childhood asthma.
Purpose of the Study:
- To investigate the association between von Willebrand factor (vWF) levels and chronic inflammation in children with recurrent wheezing and asthma.
- To determine if vWF levels can serve as an indicator for the development of asthma.
- To explore the relationship between vWF levels and the severity of wheezing episodes.
Main Methods:
- Prospective cohort study involving children with recurrent wheezing and asthma.
- Patients were categorized into three groups based on the number of wheezing episodes.
- von Willebrand factor levels were measured at admission and post-treatment.
Main Results:
- von Willebrand factor (vWF) levels were significantly elevated in children with more frequent wheezing episodes compared to controls.
- vWF levels remained high in the most severely affected group even after treatment.
- vWF levels decreased to normal ranges in children with fewer wheezing episodes after treatment.
Conclusions:
- Elevated vWF levels are indicative of endothelial dysfunction in children with recurrent wheezing.
- The magnitude of vWF elevation correlates with the number of wheezing episodes.
- Sustained high vWF levels, despite symptom relief, suggest ongoing chronic inflammation and potential asthma development.
Objective:
To improve our knowledge and to understand how the level of von Willebrand factor indicates the development of chronic inflammation in children with recurrent wheezing and asthma.
Material And Methods:
It was a prospective cohort study. This study was conducted in children with recurrent wheezing and asthma who were referred to a children's hospital during 2017-2018. Patients were divided into 3 groups depending on the number of episodes of wheezing. Patients were examined for von Willebrand factor levels at admission and after treatment. Data analysis was performed with Statsofta Statistica Version 8 (Tulsa, OK).
Results:
WF1 levels in Group 2 and 3 children statistically significantly increased in comparison with the control group (p<0.001). WF2 levels remained elevated only in Group 3 patients (p<0.001). WF2 levels in Group 1 and 2 decreased to the indices of the control group (p>0.05). The WF2 significantly decreased after treatment in Group 2 children (p=0.0000, T=0) and Group 3 (p=0.0000, T=0).
Conclusion:
levels of Willebrand factor indicate the presence of endothelial dysfunction. The level of Willebrand factor in the peak period of wheezing depends on the number of episodes of wheezing in history. Persistent high rates of Willebrand factor, even after the relief of clinical symptoms, indicates the present of chronic inflammation and can be regarded as the formation of asthma in children.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
