brij-58 and Dermatitis--Atopic

Corticosteroids are the mainstay of therapy for atopic dermatitis, but long-term use is associated with adverse effects. We sought to evaluate the clinical efficacy of two steroid-sparing creams for atopic dermatitis. Twenty patients were enrolled in an investigator-blinded, bilateral comparison study. Patients applied pimecrolimus cream twice daily to a target lesion on one side of the body and also applied a topical medical device cream three times daily on a symmetrical target lesion on the opposite side of the body for four weeks. Clinical assessments including Physician Global Assessment (PGA), Target Lesion Symptom Score (TLSS), subject self-assessment and digital photography were performed at the baseline, 2 week, and 4 week visits. Seventy-five percent of patients (pimecrolimus, 15 of 20; topical medical device, 15 of 20) were rated "clear" (0) or "almost clear" (1) by PGA for both medications after four weeks. Percent improvement of the PGA from randomization for pimecrolimus cream and the topical medical device cream were 72.50 and 71.67 respectively (P=0.9283). PGA scores decreased significantly from baseline for both treatments (P=0.004). Overall, there was no statistically significant difference between treatment groups for PGA scores throughout the study (P=0.8236). No cutaneous side effects were noted. Our study was limited by a small sample size and lack of double-blinding; however, both treatments were found to be safe and effective in treating atopic dermatitis over four weeks. Significant improvements were noted for all efficacy variables. In conclusion, a lipid-rich, non-steroidal, topical medical device cream was as effective in improving atopic dermatitis as pimecrolimus cream.

The atopy patch test (APT) is an in vivo model to study the induction of eczema by inhalant allergens in atopic dermatitis patients. We studied the effect of pretreatment with topical tacrolimus 0.1% on APT in nonlesional skin of patients with atopic dermatitis.. Nonlesional skin of the back of patients with atopic dermatitis (n = 8) was treated once daily for 3 weeks with tacrolimus 0.1% ointment. Cetomacrogol ointment (placebo) was used as a negative control and triamcinolone acetonide 0.1% ointment as positive control. Twenty-four hours after the last APT application, samples were taken from the three treated areas (t = 0 and 24 h) for immunohistochemical analysis.. Pretreatment with tacrolimus ointment did not suppress nonlesional skin infiltrate, in contrast to triamcinolone acetonide. Furthermore, tacrolimus did not inhibit the induction of the APT macroscopically (t = 24 h). An equal influx of T cells, eosinophils, dendritic cells, CD64+ and Fc epsilon RI-positive cells was present compared with placebo. Only CD36+ and CD68-positive cells were inhibited compared with placebo. All cell types were significantly inhibited in triamcinolone acetonide-treated sites compared with placebo.. Pretreatment with tacrolimus 0.1% ointment does not inhibit the APT reaction in patients with atopic dermatitis.
