Higher frequency of dipeptidyl peptidase IV inhibitor intake in bullous pemphigoid patients than in the French general population

Mon, 2018-12-10 00:00
Dipeptidyl-peptidase-IV-inhibitors have been suspected to induce bullous pemphigoid (BP). The objective of this study was to compare the observed frequency of gliptin intake in a large sample of 1787 BP patients diagnosed between 2012 and 2015 in France, with the expected frequency after indirect age standardization on 225412 individuals extracted from the database of the National Healthcare Insurance Agency. The secondary objective was to assess the clinical characteristics and the course of gliptin-associated BP depending on whether gliptin was continued or stopped.

Identification of a robust methylation classifier for cutaneous melanoma diagnosis

Fri, 2018-12-07 00:00
Early diagnosis improves melanoma survival, yet the histopathological diagnosis of cutaneous primary melanoma can be challenging even for expert dermatopathologists. Analysis of epigenetic alterations, such as DNA methylation, that occur in melanoma can aid in its early diagnosis. Using a genome-wide methylation screen, we assessed CpG methylation in a diverse set of 89 primary invasive melanomas, 73 nevi, and 41 melanocytic proliferations of uncertain malignant potential, classified based on interobserver review by dermatopathologists.

Neutrophil Extracellular Traps Induce Human Th17 Cells: Effect of Psoriasis-Associated TRAF3IP2 Genotype

Wed, 2018-12-05 00:00
Psoriasis lesions are rich in IL-17-producing T-cells as well as neutrophils, which release webs of DNA-protein complexes known as neutrophil extracellular traps (NETs). Because we and others have observed increased NETosis in psoriatic lesions, we hypothesized that NETs contribute to increased Th17 cells in psoriasis. After stimulating peripheral blood mononuclear cells (PBMCs) with anti-CD3/CD28 beads for 7 days, we found significantly higher percentages of CD3+CD4+IL-17+ (Th17) cells in the presence vs.

Cochrane reviews and dermatological trials outcome concordance; why Core Outcome Sets could make trial results more usable

Wed, 2018-12-05 00:00
Evidence-based healthcare requires that relevant outcomes for patients are included in clinical trials investigating treatment effects allowing subsequent systematic reviews to summarize all relevant evidence to guide clinical practice. Currently, no gold standard of outcome choice for dermatology trials and reviews exists. We systematically assessed concordance between efficacy outcomes in a random sample of 10 Cochrane Skin systematic reviews and the 220 dermatology trials included. Reviews did not include 742 (68%) of the 1,086 trial outcomes.

Gain-of-function mutations in TRPM4 activation gate cause progressive symmetric erythrokeratoderma

Wed, 2018-12-05 00:00
Transient receptor potential (TRP) channels respond to various chemical and physical stimuli by mediating cation influx. The skin expresses abundant TRP channels of different subtypes, which play an essential role in the maintenance of skin functionality. Here, we report cases of mutations in TRPM4 which encodes TRP melastatin 4 (TRPM4), a Ca2+-activated monovalent cation channel, as a cause of an autosomal-dominant form of progressive symmetric erythrokeratoderma (PSEK). In three separate families with PSEK, we identified two missense mutations (c.3099C>G and c.3119T>C) that produce p.Ile1033Met and p.Ile1040Thr, both of which are located in the S6 transmembrane domain of TRPM4 protein.

The IL-1 pathway is hyperactive in Hidradenitis suppurativa and contributes to skin infiltration and destruction

Wed, 2018-12-05 00:00
Hidradenitis suppurativa (HS; also designated as acne inversa) is a chronic inflammatory disease characterized by painful purulent skin lesions and progressive destruction of skin architecture. Despite the high burden for the patients, pathogenetic pathways underlying HS alterations remain obscure. Investigating the lesional HS cytokine pattern, IL-1β turned out as a highly prominent cytokine, being overexpressed even compared to psoriatic lesions. Analyses of IL-1β-induced transcriptome in various cell types disclosed an overlap of upregulated molecules causing immune cell infiltration and extracellular matrix degradation, as well as of specific cytokines including IL-6, IL-32, and IL-36.

A Phase 2 Randomized Trial of Apremilast in Patients With Atopic Dermatitis

Wed, 2018-12-05 00:00
and Purpose: A phase 2, double-blind, placebo-controlled trial evaluated apremilast efficacy, safety, and pharmacodynamics in adults with moderate to severe atopic dermatitis (AD).

Are environmental factors for atopic eczema in ISAAC Phase Three due to reverse causation?

Mon, 2018-12-03 00:00
Some previously described environmental associations for atopic eczema (AE) may be due to reverse causation. We explored the role of reverse causation by comparing individual- and school-level results for multiple AE risk factors.ISAAC Phase Three surveyed children within schools (the sampling unit) on AE symptoms and potential risk factors. We assessed the effect of these risk factors on AE symptoms using mixed-effect logistic regression models, first with individual-level exposure data and second with school-level exposure prevalence.

Monoclonal antibodies targeting the immune checkpoint proteins programmed cell death protein 1 (PD-1), its ligand PDL-1, and cytotoxic T lymphocyte-associated antigen 4 have been successfully used to extend survival of patients with some solid tumor types. However, it is not yet possible to predict an individual’s response to an immune checkpoint inhibitor. Previous studies showed that a high tumor mutation burden increases generation of neoantigens, increases tumor immunogenicity and may increase the likelihood of benefit from these inhibitors.

Collections—A New Feature of the JID Connector

Sat, 2018-12-01 00:00
The JID Connector ( is an online-only component of the Journal of Investigative Dermatology. Conceived and implemented several years ago by then–JID Editor Barbara Gilchrest, the JID Connector features unique content that is anticipated to be of special interest and accessible to trainees and clinicians. We also hope that the JID Connector will represent a gateway to content that appears in the online and print versions of the JID and that the value of the JID will be enhanced as a result.

Based on the success of a mutant heat shock protein (HSP70i) in preventing vitiligo in mice by reducing dendritic cell activation and diminishing T cell infiltration, Henning and colleagues attempted vitiligo treatment with this mutant HSP70i in Sinclair swine, an experimental model that more closely resembles human disease. Treatment of affected pigs with DNA plasmid encoding modified HSP70i, which harbors a single modification within the dendritic cell-activating region, via DNA jet injection led to persistent repigmentation concomitant with an influx of T cells and melanocyte repopulation.
