Your spouse’s persistent and recurrent low platelet count (thrombocytopenia), especially with multiple dengue episodes (2024, August 2025, and recent), combined with a significantly prolonged APTT of 85.2 seconds (normal usually 25–35 seconds), is concerning and not typical for simple dengue recovery.
Dengue does cause platelet drop during acute phase, but:
• Platelets usually recover within 7–14 days after fever subsides in uncomplicated cases.
• Repeated dengue infections (especially secondary dengue) can cause more severe thrombocytopenia, but persistent low platelets months later + drastic recurrent drops + very prolonged APTT strongly suggest something beyond just dengue sequelae.
The prolonged APTT indicates a coagulation abnormality — likely deficiency or inhibitor in the intrinsic pathway (factors VIII, IX, XI, XII, or lupus anticoagulant / antiphospholipid antibodies).
This is not normal post-dengue and raises red flags for:
• Antiphospholipid syndrome (APS) — common cause of prolonged APTT + thrombocytopenia + recurrent thrombosis risk (even without clots yet)
• Immune thrombocytopenia (ITP) triggered or unmasked by dengue
• Acquired factor deficiency (rare post-viral)
•
Liver dysfunction (mild subclinical — dengue can affect liver) — though
LFT not shared
•
Vitamin K deficiency or DIC (less likely without bleeding/fever)
The attached report appears to be an anti-cardiolipin antibody (aCL) test (IgG and IgM), but the values are not clearly readable in the image. It mentions “low/medium positive” in some units, which could support antiphospholipid syndrome if positive. This needs urgent clarification.
Next Steps
1. Urgent consultation (within 1–3 days) — do not wait:
• Hematologist (best choice for thrombocytopenia + prolonged APTT)
• Or Clinical immunologist / Rheumatologist (if APS suspected)
2. Essential tests to request immediately:
• Repeat platelet count (current level)
• Peripheral smear — to see platelet morphology & rule out pseudothrombocytopenia
• Full coagulation profile: PT, APTT mixing study (to differentiate factor deficiency vs inhibitor), fibrinogen, D-dimer
• Lupus anticoagulant (LA) (dRVVT method) + anti-cardiolipin IgG/IgM repeat (quantitative values)
• Anti-beta2 glycoprotein I antibodies (IgG/IgM) — completes APS workup
• ANA + anti-dsDNA (rule out SLE)
•
Liver function tests (
LFT) + ultrasound abdomen (liver/spleen size)
• Bone marrow aspiration — only if platelets
Health Tips
• Avoid aspirin, NSAIDs (ibuprofen, diclofenac), or any blood thinners until evaluated
• Avoid alcohol, smoking, herbal supplements — can worsen bleeding risk
• No heavy lifting, contact sports, or trauma
• Soft toothbrush, avoid forceful nose blowing
• Watch for red flags (go to emergency immediately):
• Bleeding gums, nosebleeds, blood in urine/stool
• Black stools, vomiting blood
• Sudden severe headache, vision change, weakness
• Bruising without cause
This is treatable — if dengue-related immune thrombocytopenia or early APS, steroids, IVIG, or hydroxychloroquine can control it. But urgent hematology evaluation is needed to prevent complications.
