Atopic dermatitis (AD) is one of the most common skin diseases, whose incidence is increasing in industrialized countries. The epicutaneous application of a hapten, such as 2,4-dinitrochlorobenzene (DNCB), evokes an experimental murine AD-like reaction. Glycomacropeptide (GMP) is a dairy bioactive peptide derived from hydrolysis ofκ-casein by chymosin action. It has anti-inflammatory, prebiotic, and immunomodulatory effects. The present study was aimed to investigate the effect of GMP administration on DNCB-induced AD in rats. The severity of inflammatory process, pruritus, production of cytokines, and total immunoglobulin E (IgE) content were measured, and the histopathological features were analyzed. GMP reduced the intensity of inflammatory process and edema of DNCB-induced dermatitis, with a significant decrease in eosinophils recruitment and mast cells hyperplasia. In addition GMP suppressed the serum levels of total IgE and IL-4, IL-5, and IL-13 expression in AD-lesions. Besides, the levels of IL-10 were significantly increased. Remarkably, GMP administration before AD-induction abolished pruritus in dermatitis-like reactions in the rats. Taken together, these results indicate that GMP has an inhibitory effect on AD by downregulating Th2 dominant immune response, suggesting GMP as a potential effective alternative therapy for the prevention and management of AD.

The SWItch (SWI)3-related gene (SRG3) product, a SWI/Sucrose Non-Fermenting (SNF) chromatin remodeling subunit, plays a critical role in regulating immune responses. We have previously shown that ubiquitous SRG3 overexpression attenuates the progression of Th1/Th17-mediated experimental autoimmune encephalomyelitis. However, it is unclear whether SRG3 overexpression can affect the pathogenesis of inflammatory skin diseases such as atopic dermatitis (AD), a Th2-type immune disorder. Thus, to elucidate the effects of SRG3 overexpression in AD development, we bred NC/Nga (NC) mice with transgenic mice where SRG3 expression is driven by the β-actin promoter (SRG3β-actin mice). We found that SRG3β-actin NC mice exhibit increased AD development (e.g., a higher clinical score, immunoglobulin E (IgE) hyperproduction, and an increased number of infiltrated mast cells and basophils in skin lesions) compared with wild-type NC mice. Moreover, the severity of AD pathogenesis in SRG3β-actin NC mice correlated with expansion of interleukin 4 (IL4)-producing basophils and mast cells, and M2 macrophages. Furthermore, this accelerated AD development is strongly associated with Treg cell suppression. Collectively, our results have identified that modulation of SRG3 function can be applied as one of the options to control AD pathogenesis.

Atopic dermatitis (AD) is one of the most prevalent inflammatory disease among non-fatal skin diseases, affecting up to one fifth of the population in developed countries. AD is characterized by recurrent pruritic and localized eczema with seasonal fluctuations. AD initializes the phenomenon of atopic march, during which infant AD patients are predisposed to progressive secondary allergies such as allergic rhinitis, asthma, and food allergies. The pathophysiology of AD is complex; onset of the disease is caused by several factors, including strong genetic predisposition, disrupted epidermal barrier, and immune dysregulation. AD was initially characterized by defects in the innate immune system and a vigorous skewed adaptive Th2 response to environmental agents; there are compelling evidences that the disorder involves multiple immune pathways. Symptomatic palliative treatment is the only strategy to manage the disease and restore skin integrity. Researchers are trying to more precisely define the contribution of different AD genotypes and elucidate the role of various immune axes. In this review, we have summarized the current knowledge about the roles of innate and adaptive immune responsive cells in AD. In addition, current and novel treatment strategies for the management of AD are comprehensively described, including some ongoing clinical trials and promising therapeutic agents. This information will provide an asset towards identifying personalized targets for better therapeutic outcomes.

Abstract Atopic dermatitis (AD) is a chronic recurrent inflammatory skin disease in patients with atopy. Atopy itself, is defined as a predisposition to develop immune response with overproduction of immunoglobulin E to low doses of allergens. AD is one of the most common skin disorders in the developed world, affecting up to 20% of children and about 3% of adults. The pathogenesis of the disease is complex, with both genetic and environmental factors playing a significant role in it. Clinically, hallmarks of atopic dermatitis include dry, itchy skin and various cutaneous efflorescence, compatible to dermatitis or eczema. Atopic dermatitis subdivides into three morphological variants manifesting during infancy, childhood and adulthood. Various environmental factors and associated diseases may have serious influence on the clinical course or may trigger disease relapses. The aim of this review article is to serve as a comprehensive overview of the etiology, pathogenesis, clinical course and diagnosis, as well as potential challenges facing the successful treatment of atopic dermatitis.

SUMMARY Atopic dermatitis is a common skin disease. Its increased incidence has changed the focus of research on atopic dermatitis toward epidemiology, prevention, and treatment. Evidence suggests that intestinal microbiota plays an important role in the pathogenesis of atopic dermatitis inducing immunosuppression, but its exact mechanism is still unclear. Probiotics have been widely reported to act on the immune system. They are living microorganisms with immunomodulatory effects that stimulate Th1 cytokines and suppress the Th2 response, which are being researched for the treatment of several diseases. Probiotics most commonly used are part of the intestinal microflora like lactobacilli, bifidobacteria, and enterococci. We describe here a case of evident response to the use of probiotics in a girl with severe atopic dermatitis, with a significant change in severity scores of atopic dermatitis (BSA/SCORAD/FDLQI). Modulation of the intestinal microbiota with probiotics may offer a way to prevent or treat allergic diseases, including atopic dermatitis.

Resveratrol-enriched rice (RR) was developed using genetic engineering to combine the properties of resveratrol and rice. To evaluate the effect of RR on pruritic skin inflammation in atopic dermatitis (AD)-like skin lesions, we used dinitrochlorobenzene (DNCB)-induced NC/Nga mice and an in vitro 3D skin model. Normal rice (NR), resveratrol, and RR were topically applied to mice dorsal skin, following which the dermatitis index and scratching frequency were calculated. Histological examination was performed by hematoxylin and eosin and immunohistochemistry staining of IL-31 level. The level of immunoglobulin E (IgE) and IL-31 in the serum was determined by enzyme-linked immunosorbent assay (ELISA). The cytotoxicity of RR and the expression levels of pro-inflammatory cytokines were also determined in cultured human keratinocytes and a 3D skin model. RR significantly reduced scratching frequency, decreased the dermatitis severity and trans-epidermal water loss (TEWL) and improved skin hydration in DNCB-induced NC/Nga mice. RR also significantly decreased serum IL-31 and IgE levels and suppressed the production of IL-6 in human keratinocytes and the 3D skin model. Our study indicates that the synergistic effect of rice and resveratrol manifested by the topical application of RR can serve as a potential alternative therapy for chronic skin inflammatory diseases such as AD.

Alopecia areata (AA) and vitiligo are both common skin diseases of autoimmune origin. Both alopecia areata and vitiligo have shown to be affected by oxidative stress. The present work is aimed at evaluating and comparing the serum proinflammatory cytokine levels in AA and nonsegmental vitiligo (NSV). A cross-sectional study was conducted of 33 patients with AA, 30 patients with NSV, and 30 healthy controls. Serum levels of interferon γ (IFN-γ), interleukin- (IL-) 1β, and IL-6 were determined quantitatively by ELISA method. Our analysis identified a signature of oxidative stress associated with AA and NSV, characterized by elevated levels of IFN-γ (AA: p=0.007283; NSV: p=0.038467), IL-1β (AA; NSV: p≤0.001), and IL-6 (AA; NSV: p≤0.001). IL-6 was also significantly increased in NSV patients in comparison with AA patients (p=0.004485). Our results supported the hypothesis that oxidative stress may play a significant role in promoting and amplifying the inflammatory process both in AA and vitiligo. The complex understanding of both disease etiopathogenesis involves interrelationships between oxidative stress and autoimmunity. The clinical study registration number is RNN/266/16/KE.

The review represents the analysis of modern data on the pathogenesis and methods of treatment of atopic dermatitis (AtD). The literature search was carried out using the Scopus, Web of Science, MedLine, The Cochrane Library, EMBASE, e-library databases. AtD is one of the most common skin diseases, aff ecting about 20% of children and 5% of adults in advanced countries. The disease is multifactorial by its etiology. Among the genetic factors, the main attention is paid to the mutation of the gene encoding the synthesis of fi laggrin-protein involved in the functioning of the skin barrier. The role of cytokines regulating the synthesis of IgE — interleukins (IL) -4, -5, -12, -13, -31 is studied in the genesis of immune disorders in AtD. Steady-state stress accompanying pruritic dermatitis contributes to the development of anxiodepressive сonditions degrades quality of life, and stress-related increase of cortisol level may be essential in impairing the barrier function of the skin. Among the new approaches to the treatment of patients with AtD, the possibilities of using Selank, which represents the group of regulatory peptides and narrow-band phototherapy of the 311 nm range, are discussed.

Vitamin D Levels

Along with its role in regulation of calcium metabolism and bone health, vitamin D is essential for immune system integrity. Vitamin D is an essential immunomodulatory vitamin that interact with the immune system in response to foreign antigens. This interaction is mediated by the vitamin D receptors (VDR) expressed on the surface of various immune cells. Vitamin D has an inhibitory effect on synthesis and release of immunoglobulin E and thus is closely related to atopic disorders. Vitamin D deficiency is a risk factor for bronchial asthma, and it increased asthma-related exacerbation. Low vitamin D levels are encountered in patients with allergic rhinitis and increase the severity of the disease. Other allergic conditions such as atopic dermatitis, contact dermatitis, and food allergy were reported to be significantly correlated with vitamin D serum levels. Despite the established correlation between vitamin D and atopic disorders, double-blinded randomized controlled studies are still lacking to approve this relationship and to provide clear guidelines for the recommended supplementary doses of vitamin D to prevent or treat these conditions. This article aims to review the relationship between vitamin D deficiency and atopy in children.
