Dengue and calcium

Area of Science:

• Medical Research
• Infectious Diseases
• Biochemistry

Background:

• Dengue fever is a serious viral illness requiring supportive care, as no specific antiviral treatment exists.
• Current dengue management focuses on fluid balance, organ support, and metabolic correction.
• Limited evidence exists on calcium homeostasis's role in dengue pathogenesis and clinical outcomes.

Purpose of the Study:

• To review the current evidence on calcium homeostasis in dengue.
• To explore the potential link between calcium derangements and dengue severity.
• To investigate calcium's role in dengue immunopathogenesis, cardiac dysfunction, and platelet abnormalities.

Main Methods:

• Literature review of studies investigating calcium levels in dengue patients.
• Analysis of in vitro studies examining calcium's effects on cardiac function and immunopathogenesis.
• Evaluation of studies on calcium's role in platelet aggregation in dengue.

Main Results:

• Hypocalcemia (low blood calcium) is observed in dengue infections, potentially worsening with disease severity.
• Calcium homeostasis derangements may contribute to myocardial dysfunction and cardiac arrhythmias in dengue.
• Calcium influences platelet aggregation, a critical factor in dengue's hemorrhagic manifestations.

Conclusions:

• The multifactorial causes of hypocalcemia in dengue require further elucidation.
• Maintaining calcium homeostasis may be crucial for managing cardiac dysfunction and immunopathogenesis in dengue.
• Additional well-designed clinical trials are necessary to determine the therapeutic utility of calcium in dengue management.
