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.

Purpose: Sulfated polysaccharide (SP) from Codium species has been reported for its anti-inflammatory activities. However, the effect of SP from C. edule on allergic responses has not been studied. The study was conducted to determine the effect of SP (F1) from C. edule on allergic contact dermatitis (ACD) induced by 2,4-dinitrofluorobenzene (DNFB) in female BALB/c mice. Methods: F1 was isolated using DEAE Sepharose Gel Chromatography and chemically identified by LC-MS analyses. The effects of F1 on changes in ear thickness, allergic responses, and histology were evaluated. The effects of F1 on the production of inflammatory cytokines IFN- γ and TNF-α in serum were also quantified and compared with standard prednisolone therapy. Results: F1 was identified as a heteropolysaccharide with β-D-galactans and β-L-arabinans units. F1 was non-toxic at 2000 mg/kg. Administration of F1 in DNFB-challenged mice significantly suppressed the increase in ear thickness, erythema, desquamation, and proliferation of inflammatory cells. F1 significantly decreased the production of inflammatory markers, IFN- γ and TNF-α in a dose-dependent manner when compared to the untreated group (p<0.05). Conclusion: Results suggest that F1 from C. edule is a bioactive sulfated heteropolysaccharide with anti-inflammatory activity and might be a valuable candidate molecule for the treatment of allergic diseases such as ACD.
