Elevated serum soluble E-selectin levels in Korean children with measles

Area of Science:

• Immunology
• Pediatrics
• Viral Infections

Background:

• Measles is a highly infectious viral illness with uncertain pathogenesis.
• E-selectin is implicated in inflammatory skin conditions but its role in measles was unclear.
• Soluble E-selectin (sE-selectin) is a marker of endothelial activation.

Purpose of the Study:

• To investigate elevated serum sE-selectin levels in children diagnosed with measles.
• To compare sE-selectin levels in measles patients with those in atopic dermatitis, atopic asthma, and healthy controls.

Main Methods:

• Sandwich enzyme-linked immunosorbent assay (ELISA) was used for quantification.
• Serum sE-selectin and tumor necrosis factor (TNF)-alpha levels were measured.
• Study included children with measles, atopic dermatitis, atopic asthma, and healthy controls.

Main Results:

• Children with measles exhibited significantly higher serum sE-selectin levels.
• No significant correlation was found between sE-selectin levels and measles rash duration or complications.
• Serum TNF-alpha levels were higher in measles patients than in atopic dermatitis patients.

Conclusions:

• Elevated serum sE-selectin levels in children with measles suggest potential involvement of CLA+ T lymphocytes.
• This finding may offer insights into the pathogenesis of measles rash.
• Further research is warranted to elucidate the precise mechanisms.
