Background

To investigate efficacy and safety of Dialyzed Leukocyte Extracts (DLE) as adjuvant therapy for moderate atopic dermatitis (AD).

Design

Double blind, placebo-controlled, randomized, clinical single-centre trial.

Methods

Fifty-eight paediatric-patients with moderate AD were enrolled and randomized in two groups: 1) Conventional treatment (CT) + DLE: Cetirizine (0.25mg/kg), once daily/4 weeks, Chlorpheniramine (0.35 mg/Kg), daily divided in 3 doses/4 weeks; and topical Methylprednisolone 0.1%, twice daily/10 days, then once daily/10 days, and ending every 48h/10 days; plus oral DLE (2mg/5mL), daily/5 days, then every 72h to complete one month. 2) CT + placebo, same dosage and administration. Main outcome measures: Severity of skin lesions evaluated with SCORAD-Index, and immunophenotypical changes at day 14, and at end of treatment.

Results

A significant clinical improvement was observed since day 14 with both, CT and CT + DLE therapy, no significant differences in the main clinical outcome measures were found among groups; however a diminished frequency of CD8+ CD103+ cells, and increased frequency of CLA + cells, was observed in CT + placebo-group.

Conclusions

Adjuvant therapy with DLE was safe and well-tolerated. Despite both groups of patients significant improved after treatment, individuals treated with DLE preserved cell subsets related to skin immunological regulation, and avoided systemic expansion of cells related to skin inflammation.
