Lama Skieker: Understanding Thrombocytopenia in Malaria
Lama Skieker, Clinical Pathologist at Bader Alsama Barka, shared a post on LinkedIn:
“As a continuation of my previous post on thrombocytopenia, I would like to highlight an interesting clinical example: thrombocytopenia associated with malaria.
I would also like to sincerely thank Hemostasis Today for sharing my previous post and helping extend this educational discussion within the laboratory medicine and haemostasis community.
Why Does Thrombocytopenia Occur in Malaria?
Thrombocytopenia is one of the most frequent haematological abnormalities seen in malaria, reported in approximately 60–75% of cases in many studies, although prevalence varies according to the population, Plasmodium species, disease severity .
The mechanism is multifactorial, and in most patients it reflects increased peripheral platelet turnover rather than primary bone-marrow failure.
What is happening to the platelets?
Platelet activation and peripheral consumption
Parasitised RBCs and malaria-associated endothelial activation stimulate platelets.
Endothelial activation and VWF
Malaria-associated endothelial activation increases the release of VWF, while reduced ADAMTS13 activity may allow highly adhesive ultra-large VWF multimers to persist, promoting platelet adhesion and consumption.
Note: ADAMTS13 activity refers to the ability of the ADAMTS13 enzyme to cleave ultra-large VWF multimers into smaller, less platelet-adhesive forms.
- Splenic sequestration and clearance
- Immune-mediated destruction
- Oxidative injury
Malaria-associated inflammation and oxidative stress may alter platelet membranes, further shortening platelet survival.
Bone-marrow effects
Transient abnormalities of megakaryopoiesis may occur, particularly in severe or prolonged disease.
Coagulation consumption in severe malaria.
However, thrombocytopenia in malaria does not automatically indicate DIC.the coagulation profile and clinical context should be evaluated.
Platelets recover rapidly after successful malaria treatment:
Because megakaryopoiesis is generally preserved and the marrow is already releasing young platelets, the circulating platelet count may recover rapidly once peripheral consumption decreases.
A practical laboratory message
When evaluating thrombocytopenia in a patient with malaria, don’t look at the platelet count in isolation.
Consider:
Platelet count with peripheral smear, IPF or MPV, parasitaemia, coagulation profile and serial platelet trend.
Note: IPF (Immature Platelet Fraction) reflects newly released platelets from the bone marrow.
If severe thrombocytopenia persists despite parasite clearance, consider additional causes such as DIC, sepsis, drug-induced thrombocytopenia, TMA or TTP, hypersplenism or underlying marrow pathology.
Key Message :
The platelet count is not only a number – it can tell us a story about production, consumption and recovery.”
