A Prospective Study on Different Doses of Gammaglobulin Plus Aspirin in the Pediatric Kawasaki Disease and the Impacts on CRP and WBC Levels.

Objective: To evaluate the efficacy of different doses of gammaglobulin combined with aspirin in treating pediatric Kawasaki disease and its impact on C-reactive protein (CRP) and white blood cell (WBC) levels.

Methods: A prospective study was conducted with 150 children (3groups) diagnosed with Kawasaki disease. Group A received a higher dose of intravenous gammaglobulin (2.5 g/kg) combined with aspirin, Group B received a standard dose of intravenous gammaglobulin (2 g/kg) combined with aspirin, and Group C received a lower dose of intravenous gammaglobulin (1 g/kg) combined with aspirin. All groups received oral aspirin therapy (30 mg/kg/day) for a standard duration. The time to symptom improvement, treatment efficacy, laboratory parameters, and adverse reactions were monitored and analyzed.

Results: Group B showed a shorter time to symptom relief compared to Groups A and C, particularly in fever reduction, mucosal congestion, cervical lymph node enlargement, and limb symptoms. The total effective rate was higher in Group B compared to Groups A and C. Group B showed improvements in WBC, CRP, ESR, and PLT levels.

Conclusion: Standard-dose intravenous gammaglobulin combined with aspirin was more effective in treating pediatric Kawasaki disease compared to higher and lower doses. The treatment regimen in Group B resulted in shorter time to symptom relief, higher total effective rate, improved biochemical markers. Incidence of adverse reactions was similar among the three groups, demonstrating the safety of standard dosage.
