Abstract

Diet is a modulator of inflammation that might impact inflammatory skin diseases. To assess the relationship between pro-inflammatory dietary patterns and incident psoriasis, psoriatic arthritis (PsA), and atopic dermatitis (AD). We conducted cohort studies among women in the Nurses' Health Study II. The Empirical Dietary Inflammatory Pattern (EDIP) score was calculated at baseline and every 4 years. Incident psoriasis, PsA, and AD were assessed by validated self-report. We used multivariable-adjusted Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between EDIP quintiles and risk for psoriasis, PsA, and AD. We had 85,185 participants in the psoriasis analysis and 63,443 in the AD analysis. There were 1432 cases of psoriasis, 262 cases of PsA, and 403 cases of AD. Pro-inflammatory dietary patterns were not associated with the risk for outcomes in multivariable models (all P values for trend >.05). HRs comparing the highest to the lowest EDIP quintile were 0.99 (95% CI 0.83-1.18) for psoriasis, 1.22 (95% CI 0.81-1.83) for PsA, and 0.96 (95% CI 0.69-1.34) for AD. Recall and self-report. Our findings do not support dietary inflammatory potential as a risk facto...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
