From Dengue protocol to complication control.
From ATOM:
Dengue usually settles by Day 5–7.
If the patient is still unwell after Day 5, it is NOT dengue anymore ,it is a complication.
Dengue has a fixed timeline:
• Day 1–3: Fever + viremia
• Day 4–6: Critical leak window
• Day 7 onwards: Recovery
If the patient is still sick after Day 5, you must assume a secondary problem.
Never keep blaming dengue after Day 5.
What makes a dengue patient sick after Day 5?
1. Fluid overload / pulmonary edema (MOST COMMON)
This is the #1 reason patients are breathless or deteriorating after Day 5.
Because the leak has stopped, but the excess fluids remain inside → lungs fills .
Treatment: Stop fluids, diuretics, oxygen, CPAP/ventilation.
2. Late bleeding.
Once leak closes, patients may develop occult or overt bleeding.
• Falling hematocrt Tachycardia ,Abdominal pain,Drop in Hb.
Treatment: Blood transfusion.
3. Secondary bacterial infection.
After the immune storm settles, immunity drops → bacterial infection with restart of fever etc.
Treatment: Start antibiotics based on clinical suspicion.
4. Myocarditis / cardiomyopathy.
Dengue can cause myocardial depression.
Signs:
• Hypotension despite no leak.
• Gallop, basal crepts.
• Elevated troponin.
• Echocardiographic global hypokinesia.
Treatment: Inotropes, cautious fluids, ICU.
5. Liver failure / severe hepatitis!
Severe hepatitis in dengue peaks around Day 5–7.
Treatment: N-acetylcysteine, tight ICU support.
6. Prolonged marrow suppression (platelets + WBCs).
Rare, but can occur ,counts don’t rise.
This is when eltrombopag MAY be used, but usually only after acute dengue is over ,recent data show early use may help too as antiviral.
7. Hemophagocytic lymphohistiocytosis (HLH) ,rare but deadly .
remember RARE MANIFESTATION OF COMMON DISEASES VERY COMMON
Triggers persistent, cytokine storm
, fever after dengue,
Think HLH if:
• Fever > 7 days
• Ferritin very high
• Cytopenias
• Organomegaly
Need urgent Dexamethasone to start with ,and plus etoposide if needed ( already written ) .
If a dengue patient is unwell after Day 5, it is no longer the virus ,
it is either fluid overload, bleeding, infection, myocarditis, or organ failure or HLH .
Management shifts from “dengue protocol” to “complication control.”
