Dengue fever, a viral infection transmitted by mosquitoes, can lead to a dangerous drop in platelet count, a condition known as thrombocytopenia. Platelets, essential for blood clotting, may fall to critically low levels, increasing the risk of internal bleeding. This is a major concern in dengue fever, where platelet count monitoring becomes crucial for patient survival and recovery. One treatment option gaining attention is platelet booster injections.
Types of Platelet Booster Injections
Several types of platelet booster injections are currently used to raise platelet levels in patients, particularly those with dengue fever or other conditions like chemotherapy-induced thrombocytopenia:
Eltrombopag (Revolade): A thrombopoietin receptor agonist that stimulates the bone marrow to produce more platelets.
Romiplostim (Nplate): Another thrombopoietin receptor agonist, often used for chronic immune thrombocytopenia but also investigated in cases of severe dengue.
Oprelvekin (Neumega): A recombinant form of interleukin-11, it stimulates platelet production in the bone marrow.
Platelet Transfusions: In severe cases, platelet transfusions may be required to rapidly restore platelet levels.
Mechanism of Action
Eltrombopag and Romiplostim: These drugs bind to and activate thrombopoietin receptors on megakaryocytes (precursor cells in the bone marrow that produce platelets). This stimulates the production and release of platelets into the bloodstream.
Oprelvekin: It increases platelet production by stimulating the proliferation and maturation of megakaryocytes.
By targeting the body's natural platelet production processes, these drugs help raise platelet levels gradually over a few days to weeks.
Cost of Platelet Booster Injections
The cost of these injections varies widely depending on location, brand, and availability:
Eltrombopag: Around 28000 rs per dose . Oral Tablet is also available . Costs range from $500 to $1000 per dose in U.S. and other countries
Romiplostim: Around 35000 -40000 rs per injection. Priced at approximately $1000 to $2000 per injection in U.S.
Oprelvekin: Can cost between $400 to $700 per dose. Not available in India.
In countries like India, generic versions may be more affordable, but these treatments still come with significant costs.
Efficacy of Platelet Booster Injections
Several clinical trials and studies have evaluated the effectiveness of platelet booster injections:
Eltrombopag: Studies show that it can significantly raise platelet counts in patients with immune thrombocytopenia and in some cases of dengue fever. However, its efficacy in dengue fever is still under investigation.
Romiplostim: Has shown success in boosting platelet levels in chronic immune thrombocytopenia but is not yet widely recommended for dengue.
Oprelvekin: While primarily used in chemotherapy-induced thrombocytopenia, its efficacy in dengue is uncertain.
While these injections are effective in other conditions, they are not routinely used in dengue fever due to the temporary nature of the thrombocytopenia caused by the virus. The key focus in dengue treatment is supportive care rather than relying heavily on platelet-boosting drugs.
Clinical Trials and Research
A 2021 clinical study examined the use of Eltrombopag in severe dengue cases. The results suggested a modest increase in platelet count but also noted the risk of side effects.
Romiplostim has been tested in trials for its use in critically low platelet conditions, but data on its role in dengue remains limited.
More research is needed to establish the safety and efficacy of these treatments for dengue.
Potential Hazards and Risks
Though effective, platelet booster injections carry certain risks:
Eltrombopag: May cause liver damage, blood clots, or increase the risk of leukemia in certain conditions.
Romiplostim: Can lead to bone marrow fibrosis, a condition where the bone marrow becomes scarred and dysfunctional.
Oprelvekin: Has been associated with fluid retention, heart failure, and arrhythmias.
In dengue fever, these risks may outweigh the benefits, making them a secondary option to supportive care.
Other Treatment Options for Platelet Management in Dengue
Instead of platelet booster injections, the following treatment strategies are typically recommended in dengue fever:
Hydration: Maintaining adequate fluid balance is crucial to prevent complications.
Platelet Transfusions: In cases where platelet counts drop below dangerous levels, platelet transfusions may be performed.
Papaya Leaf Extract: Some studies suggest that papaya leaf extract may help increase platelet count naturally, although results are inconsistent.
Supportive Care: Rest, hydration, and monitoring platelet levels remain the cornerstones of dengue treatment.
Tips for Managing Dengue-Related Thrombocytopenia
Stay Hydrated: Adequate fluid intake helps manage symptoms and supports overall recovery.
Monitor Platelet Levels: Regular blood tests to monitor platelet count are essential to avoid complications.
Avoid NSAIDs: Drugs like aspirin or ibuprofen can increase the risk of bleeding in dengue fever, so they should be avoided.
Platelet Boosting Foods : While not a replacement for medical treatment, some natural remedies like papaya leaf juice or kiwi fruit have been traditionally used to boost platelet counts.

While platelet booster injections like Eltrombopag, Romiplostim, and Oprelvekin can be effective in certain cases of thrombocytopenia, their use in dengue fever is still under evaluation. They may provide benefits in extreme cases, but they come with risks and high costs. In dengue treatment, supportive care remains the primary focus, with injections considered only when absolutely necessary. As research progresses, better guidelines for platelet management in dengue may emerge, offering safer, more effective solutions for patients.
