Allergic conjunctivitis: a risk factor for recurrent herpes simplex virus infections in patients with atopic dermatitis.

Background: Patients with atopic dermatitis have an increased risk of herpes simplex virus (HSV) infections.

Objectives: We carried out a retrospective, cross-sectional study to investigate the association of disease severity, concomitant atopic diseases and filaggrin mutations with the risk of cutaneous HSV infections in 463 patients with atopic dermatitis.

Materials & Methods: The correlation between predisposing factors and HSV infections was analysed using chi-square and Mann Whitney U-tests, and the relationship was further studied with binomial logistic regression to ascertain odds ratios.
