ABSTRACT Atopic dermatitis is a highly pruritic chronic inflammatory skin disorder affecting 10-20% of children worldwide. Symptoms can persist or begin in adulthood. It is also the most common cause of occupational skin disease in adults. This disease results from an interaction between susceptibility genes, the host's environment, pharmacological abnormalities, skin barrier defects, and immunological factors. New management approaches have evolved from advances in our understanding of the pathobiology of this common skin disorder.

ABSTRACT: Banhasasim-tang (BHSST) is a Korean traditional herbal formula comprising eight medicinal herbs. The aim of the present study was to investigate the anti-inflammatory effect of BHSST using macrophage and keratinocyte cell lines. First, we evaluated the effects of BHSST on inflammatory mediator and cytokine production in lipopolysaccharide- (LPS-) stimulated RAW 264.7 macrophages. BHSST markedly inhibited the production of nitric oxide (NO), prostaglandin E2 (PGE2), and interleukin- (IL-) 6. BHSST significantly suppressed the protein expression of toll-like receptor 4 (TLR4) and phosphorylated nuclear factor-kappa B (NF-κB) p65 in RAW 264.7 cells. Second, we examined whether BHSST influences the production of chemokines and STAT1 phosphorylation in tumor necrosis factor-α/interferon-γ TI-stimulated HaCaT keratinocytes. BHSST significantly suppressed the production of RANTES/CCL5, TARC/CCL17, MDC/CCL22, and IL-8 in TI-stimulated HaCaT cells. BHSST also suppressed TI-induced phosphorylation of STAT1 in HaCaT cells. These results suggest that BHSST may be useful as an anti-inflammatory agent, especially for inflammatory skin diseases.Evidence-based Complementary and Alternative Medicine 01/2015; 2015:728380.

ABSTRACT: Atopic dermatitis (AD) is one of the most common inflammatory allergic diseases with pruritic skin lesions particularly in infancy. It is considered to be the first step of atopic march and has variable disease courses. Many children with AD may resolve their AD symptoms with increasing age and may develop respiratory allergies such as asthma and rhinoconjunctivitis at certain ages. Natural course of AD has been supported by many cross-sectional and longitudinal studies in many countries. In general, atopic dermatitis tends to be more severe and persistent in young children, particularly if they have some risk factors including genetic factors. It appears that approximately 40%-70% of childhood AD will get resolved when they reach the age of 6-7 years. However, it is also observed that over half of the children with AD developed respiratory allergy during late childhood.Allergy, asthma & immunology research 03/2015; 7(2):101-5.

ABSTRACT: The prevalence of atopic dermatitis in infants is increasing worldwide. However, the nutrient intake status of infants with atopic dermatitis has not been studied properly. This study was conducted to compare the nutrient intake status of infants in the weaning period with atopic dermatitis by feeding type. Feeding types, nutrient intake status and growth status of 98 infants with atopic dermatitis from age 6 to 12 months were investigated. Feeding types were surveyed using questionnaires, and daily intakes were recorded by mothers using the 24-hour recall method. Growth and iron status were also measured. The result showed that breastfed infants consumed less energy and 13 nutrients compared to formula-fed or mixed-fed infants (p < 0.001). The breastfed group showed a significantly lower intake rate to the Dietary Reference Intakes for Koreans than the other two groups (p < 0.001). In addition, they consumed less than 75% of the recommended intakes in all nutrients, except for protein and vitamin A, and in particular, iron intake was very low, showing just 18.7% of the recommended intake. There was no significant difference in growth by feeding type, but breastfed infants showed a significantly higher rate of iron deficiency anemia (p < 0.001). Continuous management programs should be prepared for breastfed infants with atopic dermatitis, who are in a period when rapid growth takes place and proper nutrient intake is essential.Nutrition research and practice 02/2015; 9(1):57-62.
