Background: Our previous findings demonstrated that in vitro supplementation of polyphenols, extracted from seeds of red grape (Nero di Troia cultivar), to peripheral lymphomonocytes from patients affected by allergic contact dermatitis (ACD) to nickel (Ni) could reduce release of pro-inflammatory cytokines and nitric oxide (NO), while increasing levels of interleukin (IL)-10, an anti-inflammatory cytokine. Objective: To assess whether an intervention with oral administration of polyphenols leads to a reduction of peripheral biomarkers in ACD patients. Method: At T0, 25 patients affected by ACD to Ni were orally administered with 300 mg polyphenols prodie extracted from seeds of red grape (Nero di Troia cultivar) (NATUR-OX®) for 3 months (T1). Other 25 patients affected by ACD to Ni received placebo only for the same period of time. Serum biomarkers were analyzed at T0 and T1. In both groups seven drop outs were recorded. Result: At T1 in comparison to T0, in treated patients, values of IFN-γ, IL-4, IL-17, PTX3 and NO decreased, while IL-10 levels increased when compared with T0 values. Conversely, in placebo-treated patients no modifications of biomarkers were evaluated at T1. Conclusion: Present laboratory data rely on the anti-oxidant, anti-inflammatory and anti-allergic properties of polyphenols.

In the present work Tacrolimus loaded liposomal systems were developed and evaluated for their topical delivery. Neutral multilamellar liposomes (MLVs) were prepared by thin film hydration method. The amount of drug loaded into vesicles ranged from 4.4 mg per 115mg to 8.2mg per 140mg of total lipid. Entrapment efficiency of tacrolimus in liposomes was studied by altering the amount of cholesterol ratio to lipid ratio. After performing stability study at different temperatures (4, 25, and 37°C) was affirms that drug leakage increased at higher temperature. The in-vitro permeation study shows significant reduced permeation with tacrolimus liposomes compared with free tacrolimus in propylene glycol. The animal study carried out on allergic contact dermatitis (ACD) model in rats showed that 0.03% tacrolimus liposomal gel exhibited similar activity when compared with 0.03% marketed tacrolimus ointment. It is also likely that tacrolimus liposomal gel which leads no visible or palpable residue when applied on skin would be more appealing to patients than conventional ointment. Overall study suggests that tacrolimus can be effectively incorporated in liposomes and can be used for the treatment of atopic dermatitis.  Keywords: Tacrolimus; Multilamellar vesicle; Allergic contact dermatitis.   © 2010 JSR Publications.
