[Biochemical analysis of children tears in herpetic keratitis]

Area of Science:

• Ophthalmology
• Biochemistry
• Pediatrics

Context:

• Herpetic keratitis in children involves impaired corneal antioxidant defenses.
• Increased free-radical oxidation and reduced peroxidase activity are observed in the lacrimal fluid.

Purpose:

• To investigate the role of oxidative stress and antioxidant status in pediatric herpetic keratitis.
• To evaluate the potential of antioxidant supplementation in managing herpetic keratitis.
• To develop a method for predicting ophthalmoherpes relapses in children.

Summary:

• Children with herpetic keratitis exhibit heightened free-radical oxidation and diminished antioxidant protection, evidenced by increased lacrimal fluid chemiluminescence and lower peroxidase activity.
• Findings suggest that incorporating antioxidants into the comprehensive treatment of herpetic keratitis is a viable approach.
• An enzyme assay-based method has been developed to forecast the likelihood of recurrent ophthalmoherpes in pediatric patients.

Impact:

• Highlights the imbalance of oxidative-antioxidant processes in herpetic keratitis.
• Supports the integration of antioxidants into therapeutic strategies for pediatric herpetic keratitis.
• Provides a novel tool for predicting and potentially preventing disease relapses.
