Inflammatory bowel disease (IBD) with its two main subtypes Crohn's disease and ulcerative colitis is not restricted to the gastrointestinal tract. Indeed, so-called extraintestinal manifestations (EIMs) are frequent and considerably affect morbidity and mortality. The prevalence of EIMs ranges from 6 to 47%. In up to one quarter of the patients, EIMs can present even before an IBD diagnosis is established. The pathophysiology of EIMs remains elusive, although data from clinical trials demonstrating anti-tumor necrosis factor (TNF) efficacy suggest a common pathogenic link between intestinal and extraintestinal disease activity...

Dirofilariasis is a worldwide zoonotic infection that rarely affects humans and is caused by filarial nematodes of the genus Diroflaria transmitted by mosquitoes. Cutaneous dirofilariasis, due to D. repens, presents as inflammatory lesions that develop into subcutaneous nodules. These clinical symptoms may be consistent with Wells' cellulitis. Diagnosis of dirofilariasis involves demonstration of the presence of the nematode during skin biopsy and identification of the worm through macroscopic, histological and PCR analysis...

BACKGROUND: Graft versus host disease (GVHD) is a significant complication following hematopoietic stem cell transplantation in the pediatric population. The most common clinical manifestation of GVHD is in the skin. This article will present a review of key concepts related to pediatric cutaneous GVHD, including pathophysiology, clinical epidemiology, diagnosis, and treatment options. GVHD is an immune-mediated process characterized by an inflammatory immune response in acute GVHD and mixed inflammatory and fibrotic states in chronic GVHD...

There is growing evidence that inflammatory responses may help to explain how emotions get "under the skin" to influence disease susceptibility. Moving beyond examination of individuals' average level of emotion, this study examined how the breadth and relative abundance of emotions that individuals experience-emodiversity-is related to systemic inflammation. Using diary data from 175 adults aged 40 to 65 who provided end-of-day reports of their positive and negative emotions over 30 days, we found that greater diversity in day-to-day positive emotions was associated with lower circulating levels of inflammation (indicated by IL-6, CRP, fibrinogen), independent of mean levels of positive and negative emotions, body mass index, anti-inflammatory medications, medical conditions, personality, and demographics...

Dermatomyositis (DM) is an autoimmune disorder associated with a dysregulation of immune homeostasis of both the innate and adaptive immune system. Earlier data suggested that these two arms of the immune system interconnect in DM. In the current study, we analysed the association of autoantigen expression [adaptive system components: Mi2, transcriptional intermediary factor (TIF)1γ, small ubiquitin-like modifier 1 activating enzyme subunit (SAE)1, melanoma differentiation-associated protein (MDA)5] with markers of cellular stress (innate system components: MxA, p53) in skin and muscle (immunohistology and gene expression data, respectively)...

This study revealed the risk of major osteoporotic fracture in patients with sarcoidosis exposed to glucocorticoids. Current use of glucocorticoids was associated with a risk of fracture, with no difference between patients with and without sarcoidosis. Sarcoidosis per se was not associated with an increased fracture risk. INTRODUCTION: Sarcoidosis is a multi-organ, chronic inflammatory, granulomatous disorder that most frequently affects the lungs, lymph nodes, skin, eyes, and liver, but may occur in any organ, including the bones...

Cutaneous T-Cell Lymphomas (CTCL) are rare, but potentially devastating malignancies, whose pathogenesis remains poorly elucidated. Unfortunately, currently it is not possible to predict based on the available criteria in which patients the cancer will progress and which patients will experience an indolent disease course. Furthermore, at early stages this malignancy often masquerades as psoriasis, chronic eczema or other benign inflammatory dermatoses. As a result, it takes on average 6 y to diagnose this lymphoma since its initial presentation...

CD4(+)CD8(+) double-positive (DP), mature, peripheral T cells are readily detectable in a variety of species and tissues. Despite a common association with autoimmune and malignant skin disorders, however, little is understood about their role or function. Herein, we show that DP T cells are readily detectable in the blood, spleen, and peripheral lymph nodes of naïve C57BL/6 mice. DP T cells were also present in Jα18(-/-) and CD1d(-/-) mice, indicating that these cells are not NK-T cells. After skin administration of CASAC adjuvant, but not Quil A adjuvant, both total DP T cells and skin-infiltrating DP T cells increased in number...

Psoriasis is a worldwide chronic inflammatory disease, involving both skin and joints. In order to characterize psoriasis in Han Chinese population, we conducted this nationwide prospective and hospital based survey, in which 56 hospitals with departments of dermatology participated, located in 33 cities across China. A total of 12,031 outpatients with psoriasis were registered during 2009 to 2010, which the data was collected by standard questionnaires. The main data acquisition included demographics, family history, disease status and other comorbidities...

Regulatory T (Treg) cells are well known to modulate inflammatory responses. In a recent issue of Cell, Ali et al. (2017) reveal a function for Treg cells in stem cell maintenance by showing that skin-resident Foxp3(+) Treg cells preferentially localize to the hair follicle stem cell (HFSC) niche to control HFSC-mediated hair regeneration.

Pyoderma gangrenosum (PG) is a chronic inflammatory disease of unknown cause that presents as an inflammatory and ulcerative disorder of the skin. PG is often associated with an underlying systemic disease. However, the frequencies of the underlying diseases are unclear in Japanese patients. In this retrospective, observational study, all patients diagnosed with PG who visited dermatology departments of nine regional hospitals in and around Ibaraki Prefecture were collected from 1982 to 2011 or 2014. The diagnoses of PG were based on the characteristic clinical and histological appearances and ruling out of infection...

Recently, we could show that the expression levels of the key regulators of the microRNA (miRNA) maturation and transport were dysregulated in inflamed hidradenitis suppurativa (HS) tissue (Heyam et al. in Wiley Interdiscip Rev RNA 6:271-289, 2015). The RNA-induced silencing complex (RISC) is the central element of the miRNA pathway and regulates miRNA formation and function. We investigated the expression of the RISC components, namely transactivation-responsive RNA-binding protein-1 (TRBP1), TRBP2, protein activator (PACT) of the interferon-induced protein kinase R, Argonaute RISC Catalytic Component-1 (AGO1) and Component-2 (AGO2), metadherin, and staphylococcal nuclease and Tudor domain-containing-1 (SND1) in inflamed HS tissue compared to healthy and psoriatic controls by real-time reverse transcription polymerase chain reaction...

Wound healing is significantly delayed in irradiated skin. To better understand global changes in protein expression after radiation, we utilized a reverse phase protein array (RPPA) to identify significant changes in paired samples of normal and irradiated human skin. Of the 210 proteins studied, fibronectin was the most significantly and consistently downregulated in radiation-damaged skin. Using a murine model, we confirmed that radiation leads to decreased fibronectin expression in the skin as well as delayed wound healing...

BACKGROUND: Chronic inflammatory skin diseases are characterized by controlled proliferation of keratinocytes. Here, activating transcription factor 3 (ATF3) might play a fundamental role. In these inflammatory diseases, proliferation is controlled and only rarely leads to cancer development which can be supported by an inflammatory microenvironment. ATF3 is a dual function protein as it suppresses pro-inflammatory IL-6 and IL-8, but also acts as a pro-oncogenic factor by the suppression of p53...

The initial treatment of plantar fasciitis should be conservative, with most cases responding to standard physiotherapy, nonsteroidal anti-inflammatory drugs (NSAIDs), heel pads, and stretching. In cases of chronic refractory symptoms, more invasive treatment could be necessary. Noninvasive interactive neurostimulation (NIN) is a form of electric therapy that works by locating areas of lower skin impedance. The objective of the present prospective randomized controlled study was to evaluate whether the use of NIN for chronic plantar fasciitis could result in greater improvement in a foot functional score, lower levels of reported pain, reduced patient consumption of NSAIDs, and greater patient satisfaction compared with electric shockwave therapy in patients without a response to standard conservative treatment...

Lichen sclerosus (LS) is a benign, chronic, inflammatory skin disease with a predilection for the anogenital region in women. Although males can also be affected, the ratio of female to male incidence has been reported to be as high as 6-10:1 and possesses a bimodal age distribution of pre-pubertal girls and postmenopausal women [1, 2]. Affected skin usually demonstrates polygonal papules that coalesce into porcelain white plaques and can be associated with edema, telangiectasias, and comedo-like plug formation [3]...

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory dermatosis, characterized by shiny, atrophic, hypochromic papules with a predilection for the genital and perineal skin. Extragenital involvement may occur, but is rare in the isolated form. LSA more commonly affects prepubertal and postmenopausal women. We describe an unusual case of isolated extragenital LSA, restricted to the wrists and mimicking lichen planus.

AIMS: Atopic dermatitis (AD) is an allergic skin disease driven by the Th2-prone immune response. Therefore, a fundamental approach to restoring the Th1/Th2 balance is needed to treat AD. METHODS AND RESULTS: Eighteen different Lactobacillus strains isolated from Kimchi were screened to identify those that stimulated immune cells to secret Th1-type or Th2-type cytokines. Lactobacillus brevis NS1401 induced the greatest IFN-γ and IL-12 secretion and the least IL-4 production among the tested Lactobacillus strains...

Dermatologists are often faced with the challenge of patients presenting with non specific symptoms such as itching and or erythema. These symptoms may be attributed to a number of diseases, many of which are trivial, and others even life-threatening. In order to establish the correct diagnosis, dermatologists must rely on good diagnostic tools and knowledge. Dermoscopy was introduced mainly for inspection of pigmented lesions, but its use has now also spread to non-melanoma skin cancer, inflammatory diseases, and almost any skin disease...

INTRODUCTION: Psoriasis is a chronic inflammatory skin disease. Adipose tissue plays important roles in the events that regulate body metabolism. This study determined the levels of complement 3 ( C3), acylation-stimulating protein (ASP), and adipsin, which take part in the alternate complement pathway, and are synthesized in and secreted by adipose tissue. METHODS: Thirty-two patients with psoriasis were matched with 22 controls in terms of age, sex, body mass index, and lipid profiles...
