Tacrolimus versus hydrocortisone in management of atopic dermatitis in children, a randomized controlled double‐blind study: New insights on TARC, CTACK, TSLP, and E‐selectin

Abstract

Abstract Introduction Atopic dermatitis (AD) is a type of chronic inflammatory disorder that affects all age groups including children. AD is characterized by elevated inflammatory marker levels. Aim To assess the safety and effectiveness of topical tacrolimus ointment versus topical hydrocortisone cream in the treatment of pediatric AD by comparing the two treatments' ability to reduce serum cytokines. Patients and Methods One hundred AD patients who fulfilled the eligibility criteria completed this clinical study. Two groups of 50 AD patients each were selected from Tanta University's Dermatology Department., Group 1 (the hydrocortisone group) was administered topical hydrocortisone cream for a duration of 4 months. For 4 months, Group 2 was administered tacrolimus topically. Serum levels of thymus and activation regulated chemokine (TARC), cutaneous T cell attractant chemokine (CTAC), interleukin‐10 (IL‐10), interleukin‐6 (IL‐6), E selectin (E‐selectin), and thymic stromal lymphopoietin (TSLP) were measured during an evaluation of the patients by a dermatologist at the beginning and 4 months after the treatment had been started. Children's Dermatology Life Quality Index was used to assess quality of life in these patients. Results With the exception of E‐selectin, IL‐6, and IL‐10 (p > .05), the tacrolimus group had a significant reduction in TARC, CTACK, TSLP (p < .05) when compared to its baseline and when compared to the hydrocortisone group. Both groups showed a significant improvement in quality of life but no significant changes between groups were observed. Conclusion In children with AD, tacrolimus reduces inflammatory biomarkers better than hydrocortisone.
