Treatment for Dengue and Thrombocytopenia

Assessment and Hospitalization Criteria

Hospitalization is appropriate for a child with severe, life-threatening bleeding, regardless of platelet count 2
Hospitalization is indicated for children with platelet counts <20,000 and mucous membrane bleeding that may require clinical intervention 2
Children with platelet counts <20,000 who may be inaccessible or noncompliant should also be considered for hospitalization 2
Hospitalization is generally not needed for asymptomatic children with platelet counts 20,000-30,000 or those with platelet counts >30,000 with only minor purpura 2

Implement conventional critical care measures as the foundation of treatment 2
Administer platelet transfusions to rapidly increase platelet count 2
Provide high-dose parenteral glucocorticoids (30 mg/kg methylprednisolone daily for 3 days) 2
Consider intravenous immunoglobulin (IVIg), either alone or in combination with other treatments 2

Glucocorticoid therapy can increase platelet counts more quickly than observation alone 1
Prednisone at 4 mg/kg/day for 7 days, then tapered and discontinued by day 21, has shown efficacy in raising platelet counts 1, 3
Alternative regimen: high-dose methylprednisolone (10-50 mg/kg/day for 3 days) may produce rapid platelet recovery similar to IVIg 3

Observation without specific treatment may be appropriate, as 30-70% of children recover from severe thrombocytopenia within 3 weeks 1
