Begüm Ünlü, Ümit Türsen
The metabolic syndrome represents an important association of cutaneous maladies with cardiovascular illnesses. Chronic inflammation, shared risk factors (ie, smoking and alcohol consumption), treatment (ie, immunosuppressive agents and drugs that alter the lipid profile), and shared genetic risk loci have been proposed to the cause metabolic syndrome and cardiovascular morbidity of autoimmune diseases. There are many possible inflammatory mediators that are suggested to play a role in insulin resistance pathogenesis, such as tumor necrosis factor-α, interleukin-6, leptin, and adiponectin...

BACKGROUND: Methotrexate, a folate antimetabolite, is used to treat atopic dermatitis and psoriasis. Although methotrexate's therapeutic efficacy has been noted in the literature, there are few data on the efficacy of methotrexate treatment for allergic contact dermatitis. OBJECTIVE: To evaluate the efficacy and tolerability of methotrexate in treating allergic contact dermatitis at a single institution, and also to assess methotrexate efficacy in patients with chronic, unavoidable allergen exposure...

Plasmacytoid dendritic cells (pDCs) were described to accumulate in the skin of patients with psoriasis and to be recruited into the dermis upon allergen challenge in atopic dermatitis. Importantly, activation of pDCs in the skin has been identified as important initiator of psoriasis development. RNase 7 is one of the major antimicrobial peptides (AMP) secreted by keratinocytes and is expressed in significantly higher amounts in lesional skin of patients with atopic dermatitis or psoriasis than in healthy individuals...

BACKGROUND: Psoriasiform and eczematous eruptions are the most common dermatological adverse reaction linked to anti-TNF-α therapy. Yet, a detailed characterization of their immune phenotype is lacking. OBJECTIVES: We sought to characterize anti-TNF-α induced inflammatory skin lesions on a histopathologic, cellular and molecular level, compared to psoriasis, eczema (atopic dermatitis), and healthy control skin. METHODS: Histopathologic evaluation, gene expression (quantitative RT-PCR) and computer-assisted immunohistologic studies (TissueFAXS) were performed on 19 skin biopsies from IBD (n=17) and rheumatoid arthritis (n=2) patients with new-onset inflammatory skin lesions during anti-TNF-α-therapy...

Adherence to topical treatment for a variety of chronic skin conditions, such as psoriasis, acne, and atopic dermatitis, is known to be very poor. A number of factors contribute to this phenomenon, including lack of treatment efficacy and patient concerns regarding side effects, among others. At the forefront of barriers facing optimal patient adherence to topical treatment is choosing the ideal topical vehicle formulation. Medical professionals have demonstrated a lack of understanding with respect to the composition and nomenclature of the various topical formulations...

Janus kinases (JAKs) are non-receptor protein tyrosine kinases that are expressed in many tissues. Once the JAKs are activated, a cascade of further signaling events is triggered involving phosphorylation of selected receptor chain tyrosines, binding of signal transducer and activator of transcription (STAT) proteins and phosphorylation of these STATs. Due to their ability to selectively modulate immune function, targeted JAK inhibitors are promising candidates for some skin diseases such as psoriasis and atopic dermatitis...

Atopic Dermatitis (AD), a common skin disease, can occur in patients of all age, gender and ethnicity. It is an inflammatory affection, characterized by chronic and highly debilitating behavior. First-line interventions against AD include environmental measures and topical emollients, corticosteroids or calcineurin inhibitors. When these measures are not sufficient, phototherapy represents an efficient second-line option of treatment; it can be administered on its own, or in the most severe cases combined with systemic medicaments such as corticosteroids...

In recent years, there has been a growing movement towards the use of targeted therapies in treating of atopic dermatitis (AD), parallel to that which has occurred in psoriasis. Among the systemic medications being studied are subcutaneous or intravenously administered biologic drugs targeting specific molecules such as IL4, IL13, IL17, and IgE. Non-biologic oral therapies are also being developed for AD and include small molecule drugs targeting phosphodiesterase type IV (PDE4) inhibition or Janus Kinase (JAK) inhibition...

Innate lymphoid cells (ILCs) are kind of innate immune cells which can be divided into three main subsets according to their cytokine release profile, transcription factors, and surface markers. ILCs affect the initial stages of immunity in response to microbes and participate in immunity, inflammation and tissue repair. ILCs modulate immunity through resistance to the pathogens and regulation of autoimmune inflammation and metabolic homeostasis. Therefore dysregulation of ILCs may lead to chronic pathologies such as allergies (i...

BACKGROUND: Polymorphic light eruption (PLE) has been attributed to type IV, most likely delayed-type hypersensitivity response (adaptive immunity) but little is known on innate immunity, especially antimicrobial peptides (AMPs) in the disease. Abnormalities in AMP expression have been linked to pathological skin conditions such as atopic dermatitis (AD) and psoriasis. METHODS: AMP profiling was done in PLE skin samples (n,12) compared with that of healthy (n,13), atopic (n,6) and psoriatic skin (n,6)...

Tumor necrosis factor- (TNF-) like weak inducer of apoptosis (TWEAK) participates in multiple biological activities via binding to its sole receptor-fibroblast growth factor-inducible 14 (Fn14). The TWEAK/Fn14 signaling pathway is activated in skin inflammation and modulates the inflammatory responses of keratinocytes by activating nuclear factor-κB signals and enhancing the production of several cytokines, including interleukins, monocyte chemotactic protein-1, RANTES (regulated on activation, normal T cell expressed and secreted), and interferon gamma-induced protein 10...

Vitamin D plays a key role in skeletal and cardiovascular disorders, cancers, central nervous system diseases, reproductive diseases, infections, and autoimmune and dermatological disorders. The two main sources of vitamin D are sun exposure and oral intake, including vitamin D supplementation and dietary intake. Multiple factors are linked to vitamin D status, such as Fitzpatrick skin type, sex, body mass index, physical activity, alcohol intake, and vitamin D receptor polymorphisms. Patients with photosensitive disorders tend to avoid sun exposure, and this practice, along with photoprotection, can put this category of patients at risk for vitamin D deficiency...

With tattoos becoming increasingly mainstream, dermatologists are more and more often consulted by patients who are considering getting an ornamental, cosmetic, or even a medical tattoo, and who subsequently ask for advice. This includes not only patients with chronic skin diseases such as psoriasis or atopic dermatitis but also patients with other medical conditions. This review first explores the reasons why patients may want to get a tattoo and aims to offer some key information to dermatologists on what they should know about tattooing and the main risks associated with this procedure...

BACKGROUND: House dust mite/HDM atopy patch test/APT elicits positive reactions in a high fraction of atopic dermatitis/AD and healthy individuals. Experimental systems for new-onset/chronic AD are needed to support rapid therapeutic development, particularly since animal models representing human AD are lacking. While HDM APT has been considered to simulate AD, its suitability to model AD's emerging Th2/Th22 phenotype with Th1 and Th17 components is unknown. OBJECTIVE: To assess whether HDM APT reproduces AD...

The primary function of the skin is to act as a permeability barrier that prevents water loss from inside the body and external invasion such as by pathogens, harmful substances, and allergens. Lipids play a critical role in skin barrier formation by forming multi-lamellar structures in the stratum corneum, the outermost cell layer of the epidermis. Ceramide, the backbone of sphingolipids, accounts for more than 50% of the stratum corneum lipids. Acylceramides are epidermis-specific ceramide species essential for skin barrier formation...
