Dengue

Area of Science:

• Virology
• Immunology
• Epidemiology

Background:

• Dengue viruses cause self-limited or severe illness globally.
• Severe dengue, dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS), involves vascular permeability due to cytokine release.
• Epidemics and severity are influenced by enhancing and cross-reactive antibodies.

Purpose of the Study:

• To review clinical diagnosis and pathophysiology of DHF/DSS.
• To discuss parenteral treatment of DHF/DSS.
• To highlight new laboratory tests for dengue.

Main Methods:

• Review of existing literature on dengue virus infections.
• Analysis of clinical data and pathophysiological mechanisms.
• Discussion of treatment strategies and diagnostic advancements.

Main Results:

• DHF/DSS pathophysiology involves vascular permeability and coagulopathy.
• Epidemic patterns and disease severity are linked to antibody responses.
• Infant DHF/DSS suggests a role beyond secondary T-cell responses.

Conclusions:

• Understanding dengue pathophysiology is crucial for effective management.
• Antibody dynamics play a key role in dengue epidemics and severity.
• Advancements in diagnostics and treatment are essential for controlling DHF/DSS.
