Insights
A drop in platelet count during hospitalization for bronchiolitis in children may indicate a more severe illness. This finding can help guide treatment and management strategies for pediatric patients.
Area of Science:
- Pediatric Medicine
- Hematology
- Critical Care Medicine
Background:
- Bronchiolitis is a common respiratory infection in infants and young children.
- Platelet count and its changes during illness are not well-understood in the context of bronchiolitis severity.
Purpose of the Study:
- To investigate the prognostic significance of platelet count on admission and its changes during hospitalization in pediatric patients diagnosed with bronchiolitis.
- To determine if platelet count dynamics correlate with disease severity and need for intensive care.
Main Methods:
- Retrospective analysis of clinical data from 404 hospitalized pediatric patients with bronchiolitis.
- Patients were grouped based on platelet count on admission and delta platelet count (change during hospitalization).
- Statistical analysis compared disease severity markers, including oxygen therapy duration, PICU stay, and mechanical ventilation frequency, across groups.
Main Results:
- A significant decrease in platelet count (Group A) during hospitalization was associated with longer oxygen therapy, increased PICU stay, and higher rates of mechanical ventilation.
- Platelet count changes (delta platelet count) negatively correlated with the duration of oxygen therapy and PICU stay.
- No significant difference in disease severity was observed between patients with normal vs. elevated platelet counts on admission.
Conclusions:
- A declining platelet count during hospitalization for bronchiolitis in children may serve as an indicator of increased disease severity.
- Monitoring platelet count changes can offer valuable insights for managing pediatric bronchiolitis cases.
- Further research may explore the underlying mechanisms linking platelet dynamics to bronchiolitis outcomes.
Background:
The objective of this study was to investigate the significance of the platelet count on admission and platelet count changes during hospitalization in paediatric patients with bronchiolitis.
Methods:
Clinical data from 404 consecutive patients hospitalized for bronchiolitis were collected and compared after grouping according to the platelet count on admission and the delta platelet count during hospitalization (the platelet count 3-5 days after admission minus the platelet count on admission; Group A, delta platelet count < -50 × 109/L; Group B, -50 × 109/L ≤ delta platelet count ≤ 50 × 109/L; Group C, delta platelet count > 50 × 109/L).
Results:
Thrombocytosis was found in 79 (19.6%) patients, while 325 (80.4%) patients had a normal platelet count on admission. There was no difference in disease severity between these two groups. Groups A, B and C comprised 57 (14.1%), 133 (32.9%) and 214 (53.0%) patients, respectively. The patients from Group A had longer periods of oxygen therapy and stay in the paediatric intensive care unit, and a greater frequency of mechanical ventilation than the patients from Group B or Group C (all p < .05). Notably, among all the patients, the delta platelet count negatively correlated with the numbers of days of oxygen therapy (r = -0.385, p < .001) and stay in the paediatric intensive care unit (r = -0.603, p < .001).
Conclusions:
A decrease in the platelet count during hospitalization in paediatric patients with bronchiolitis may provide useful information for disease management.
