The aim of this study was to investigate the diagnostic value of the leukocyte shift index (LSI) in inflammatory pathology of the paranasal sinuses (PNS) with the rhinosinusogenic orbital complications (RSOC) in pediatric patients.
Methods and Results: The study involved 50 patients (26 boys and 24 girls) with diseases of the PNS and RSOC (reactive edema of the eyelids, orbital tissue, and purulent-septic complications of the eyelids and orbit)  aged from 1 to 17 years (mean age of 6.66±0.63 years). Group 1 included 29 patients (16 boys and 13 girls) with reactive edema of the eyelids and orbital tissue. Group 2 included 21 patients (10 boys and 11 girls) with purulent-septic RSOC. As a marker for determining the activity of the inflammatory process and the disorders of the immunological reactivity of the body, LSI (leukocyte shift index) was calculated. In general, the LSI value was 1.61±0.21 in Group 1 and 3.45±0.49 in Group 2 (P=0.001). Among patients aged between 3 and 12 years, the LSI was 1.66±0.30 in Group 1 and 3.93±0.79 in Group 2 (P=0.012). The results obtained indicate that LSI can be used to predict purulent-septic RSOC in inflammatory diseases of PNS in patients aged between 3 and 12 years. LSI values from 1.36 to 1.96 may predict the development of reactive edema of the eyelids and orbital tissue; from 3.14 to 4.72 - the development of purulent-septic complications of the eyelids and orbit.
Conclusion: The results obtained can be useful in predicting the clinical course of the RSOC in inflammatory pathology of PNS in patients in the age group of 3-12 years.
