Clinical significance of neutrophil gelatinase-associated lipocalin and galectin-7 in tape-stripped stratum corneum of acne vulgaris

Abstract

The usefulness of stratum corneum neutrophil gelatinase-associated lipocalin and stratum corneum galectin-7 as biomarkers of acne vulgaris was studied. A comparison of neutrophil gelatinase-associated lipocalin levels on the cheeks of patients with acne vulgaris at the start of the study and at the time of symptom improvement showed a significant decrease. On the other hand, the galectin-7 levels at the time of symptom improvement were significantly higher than those at the start of the study. Therefore, because the inflammation in the epidermis and hair follicles was reduced after therapy, as a result of the solution of the inflammatory eruptions caused by acne vulgaris, the neutrophil gelatinase-associated lipocalin level also showed a significant decrease after therapy. These results suggest that stratum corneum neutrophil gelatinase-associated lipocalin may be useful as an objective biomarker of changes in acne vulgaris symptoms.
