Soluble intercellular adhesion molecule-1 (sICAM-1) in patients with allergic rhinoconjunctivitis

Area of Science:

• Immunology
• Allergy Research
• Biomarker Discovery

Background:

• Intercellular adhesion molecule-1 (ICAM-1) is crucial in inflammatory diseases.
• Elevated soluble ICAM-1 (sICAM-1) may indicate disease activity.
• Allergic rhinoconjunctivitis involves inflammatory processes.

Purpose of the Study:

• To investigate serum sICAM-1 levels in allergic rhinoconjunctivitis patients.
• To compare sICAM-1 levels between patients and healthy controls.
• To explore correlations between sICAM-1 levels, gender, and symptom severity.

Main Methods:

• Serum samples from 25 allergic rhinoconjunctivitis patients and 20 healthy controls were analyzed.
• Enzyme-linked immunosorbent assay (ELISA) was used to quantify sICAM-1 levels.
• Statistical analysis compared sICAM-1 levels across groups and correlated them with clinical data.

Main Results:

• No significant difference in mean serum sICAM-1 levels was found between allergic rhinoconjunctivitis patients (212.6 ng/ml) and healthy controls (193.3 ng/ml).
• Male allergic rhinoconjunctivitis patients exhibited significantly higher sICAM-1 levels (234.5 ng/ml) compared to female patients (204.1 ng/ml) and controls.
• Elevated sICAM-1 levels correlated positively with higher symptom scores in allergic rhinoconjunctivitis patients.

Conclusions:

• Serum sICAM-1 levels do not generally differ between allergic rhinoconjunctivitis patients and controls.
• Male gender and symptom severity are associated with elevated sICAM-1 in allergic rhinoconjunctivitis.
• sICAM-1 may serve as a potential biomarker for disease severity in specific patient subgroups.
