Given the severity of the course of bronchiolitis in young children, especially with a burdened allergic history, the search for biomarkers for early diagnosis and prognosis of the disease is urgent.

Purpose - to substantiate the expediency of determining the levels of VCAM-1 and CC16 in blood serum in bronchiolitis in young children.

Material and methods. The main group consisted of 34 children with bronchiolitis without a serious allergic history. The comparison group included 33 children who suffered from bronchiolitis and had a severe allergic history. The control group consisted of 25 conditionally healthy children. The clinical and laboratory examination consisted in determining the levels of VCAM-1 and CC16 in blood serum using the immunoenzymatic method.

Results. The level of VCAM-1 in blood serum was established (55.5±1.12 ng/ml) in the children of the main group, while in the children of the comparison group the average value (164.9±1.1 ng/ml) of this indicator was 3 times higher, (AOR=3; 95% CI: 1.48-6.12; p<0.05). In children of the control group, the average level of VCAM-1 in blood serum was (41.6±1.32 ng/ml). Analysis of the average level of CC16 protein in blood serum revealed its significant increase in children of the main group (41.2±1.24 ng/ml) compared to the indicator of children with bronchiolitis with a severe allergic history (22.8±1.64 ng/ml ml), (AOR=1.6; 95% CI: 0.8-3.2; p<0.05). In children of the control group, the average value of the CC16 protein was within the reference values (16.2±2.43 ng/ml).

Conclusions. In young children with bronchiolitis, it is advisable to determine the level of CC16 and VCAM-1 protein in blood serum. It was found that the level of SS16 protein in blood serum was significantly lower in children with a severe allergic history compared to children without a severe allergic history. On the other hand, regarding the level of VCAM-1 in blood serum, its value was significantly increased in the majority of children with severe allergic history.

The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of all participating institutions. The informed consent of the patient was obtained for conducting the studies.
