Plan

For CBC with platelet countParacetamol 500mg/tab 1 tab every 4

hours for feverTepid sponge bathSupportive therapy

Increase oral fluid intakeAvoid dark colored foodsWOF bleeding episodes

Questions Questions…..

What if the CBC was normal? It has only been a 3 day Hx of fever..

A negative tourniquet test doesn’t necessarily r/o DF/DHF.. What now?

Its too early to say.. What can we do at this point? Is watchful waiting enough to prevent the complications of DF/DHF?

Recent dengue cases are noted to be more virulent than the past (cross-immunities etc)

DF/DHF Epidemiology

10,383 cases of DF/DHF noted by Nat’l Epidemiological Center of DOH (Jan-June 20)

104 deaths (case fatality of 1%)Most cases were at NCR, Region 4A, 5,6Most deaths are caused by complications

secondary to DHF and DSSMost are diagnosed LATE

Bio-Rad Dengue NS1 Antigen Test

New offer at PGH Central Lab!!Used in private hospitals since 2007 serum available in minutesMay detect 4 dengue serotypes in the

first 5 days of viremia (febrile phase)

Diagnostic Dilemma

P - pediatric patients with clinical signs of Dengue Fever, in the first 3 days of fever

I - Dengue NS1Antigen testC - virus isolation testO - sensitivity and specificity in diagnosis

of Dengue FeverM - cross sectional study

Clinical Question (Diagnostics)

What is the sensitivity and specificity of Dengue NS1Antigen test versus a viral isolation test in the diagnosis of DF/DHF in pediatric patients with clinical signs of DF in the first 3 days of viremia in a cross sectional study?

Therapeutic Dilemma

P - Pediatric patients with clinical signs of systemic viral infection (SVI)

I - ImmunologicalsC - placeboO - shortening the course of the diseaseM - RCTs

Clinical Question (Therapeutics)

In pediatric patients with clinical signs of systemic viral infection, is there a significant difference in giving immunologicals versus placebo in shortening the course of fever seen in randomized controlled trials?
