Outcome

Type Measure Description Time frame Safety issue
Primary Increase of lacrimal inflammatory cytokines Change in inflammatory cytokines in tears collected by capillary before and after treatment with Dupilumab. Analysis will be performed by flow cytometry. Concentrations of the following cytokines wil be measured: interleukin-1 ß, interleukin-3, interleukin-4, interleukin-5, interleukin-6, interleukin-8, interleukin-10, interleukin-13, interleukin-17, interferon a, Tumor Necrosis Factor a. Month 8
Secondary Comparison of the increase of lacrimal inflammatory cytokines between the 2 groups Change in inflammatory cytokines in tears collected by capillary among conjunctivitis patients versus non conjunctivitis patients, when treated with Dupilumab. Analysis will be performed by flow cytometry. Concentrations of the following cytokines wil be measured: interleukin-1 ß, interleukin-3, interleukin-4, interleukin-5, interleukin-6, interleukin-8, interleukin-10, interleukin-13, interleukin-17, interferon a, Tumor Necrosis Factor a. Month 8
Secondary Absence/Presence of demodex Presence of demodex on lashes before treatment with Dupilumab Day 0
Secondary Increase of lacrimal eosinophiles Month 8
Secondary Improvement of quality of life Improvement of quality of life for patients treated with Dupilumab, assessed with Ocular Surface Disease Index (OSDI) questionnaire, scored from 0 (normal/no ocular involvement) to 100 (severe ocular disease) Month 8
