Introduction: We performed a real-life clinical study to identify the main indications for the prescription of short-course treatment with systemic glucocorticosteroids (GCS) for steroid naive children with acute virus-induced wheezing as well as to analyze the influence of such treatment on patients' serum cortisol level, other blood tests results and the length of stay in the hospital.
Material and methods: The data of 44 patients who had acute wheezing, had no bacterial infection and were otherwise healthy were analyzed: 26 children received treatment with GCS and 18 children did not. Full blood count, biochemistry tests (Na, K, glucose) and blood cortisol levels of all patients were analyzed during treatment.
Results: The main indications for the short-term administration of systemic GCS were increased work of breathing, recurrent wheezing, clinical signs of atopy and a family history of asthma. Systemic GCS increased a sodium concentration (p = 0.014), decreased a cortisol level (p = 0.038), leukocyte (p = 0.043), neutrophil (p = 0.045), and eosinophil (p < 0.001) count in blood serum. The major reduction in the eosinophil count was observed in allergic children (p = 0.023). Older age was a risk factor for cortisol suppression (p = 0.018). The average length of stay in the hospital was longer in the intervention group (p = 0.039).
Conclusion: Even short-course treatment with systemic GCS decreases the serum cortisol level and has a significant effect on other blood tests results. Systemic GCS used for acute virus-induced wheezing treatment did not prove to reduce the average length of stay in the hospital. Objective criteria for initiation of such treatment are still lacking, which might consequently lead to the overuse of corticosteroids.
