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.
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).
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 (p0.05). The WF2 significantly decreased after treatment in Group 2 children (p=0.0000, T=0) and Group 3 (p=0.0000, T=0).
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.
