l-Histidine Supplementation in Adults and Young Children with Atopic Dermatitis (Eczema)

ABSTRACTAtopic dermatitis (AD) is an incurable, inflammatory skin condition that is prevalent ( ∼20%) in young children. There is an unmet clinical need, particularly in children, for safe interventions that target the etiology of the disease. Deficiencies in the skin barrier protein, filaggrin (FLG) have been identified as major predisposing factors in AD. In mammals,l-histidine is rapidly incorporated into epidermal FLG and subsequent FLG proteolysis releasesl-histidine as an important natural moisturizing factor (NMF). It has therefore been hypothesized thatl-histidine supplementation would be a safe approach to augment both FLG and the NMF, enhance skin barrier function, and reduce AD severity. In a clinical pilot study, adult subjects (n = 24) with AD took either a placebo or 4 g orall-histidine daily for 8 wk. Unlike the placebo,l-histidine reduced AD (34% reduction in SCORing Atopic Dermatitis scores;P

Abstract BACKGROUND: Tralokinumab is a fully human monoclonal antibody that specifically neutralizes interleukin-13, a key driver of atopic dermatitis (AD). OBJECTIVES: To evaluate the efficacy and safety of tralokinumab in combination with TCS in patients with moderate-to-severe AD who were candidates for systemic therapy. METHODS: This was a double-blind, placebo plus optional TCS-controlled phase III trial. Patients were randomized 2 : 1 to subcutaneous tralokinumab 300 mg or placebo every 2 weeks (Q2W) with TCS as needed over 16 weeks. Patients who achieved an Investigator's Global Assessment (I...

CONCLUSION: With proper treatment, nummular eczema can be cleared over a few weeks, although the course can be chronic and characterized by relapses and remissions. Moisturizing of the skin and avoidance of identifiable exacerbating factors such as hot water baths and harsh soaps may reduce the frequency of recurrence. Diseases that present with annular lesions may mimic nummular eczema and the differential diagnosis is broad. As such, physicians must be familiar with this condition so that an accurate diagnosis can be made, and appropriate treatment initiated. PMID: 32778043 [PubMed - as supplied by publisher]

AbstractPurpose of reviewA variety of skin diseases are associated with impaired barrier function. The crucial pillars in therapy of previously mentioned conditions are avoidance of triggers, skin protection and individually adapted medical therapy. Until recently, besides of topical corticosteroids, the treatment options were limited. However, a variety of new therapies of skin barrier-related skin diseases became available over the last years. Our goal was to investigate new findings and treatment options in skin diseases with barrier dysfunction, emphasizing on contact dermatitis, hand eczema and atopic dermatitis.Recen...

CONCLUSION: All patients were misdiagnosed as AD exacerbation. Therefore, EH should be considered in the differential diagnosis of AD exacerbation especially in the infants with moderate to severe AD. PMID: 32558432 [PubMed - in process]

Abstract Atopic dermatitis (atopic eczema) is a chronic relapsing and remitting inflammatory skin disease affecting one in 10 people in their lifetime. Atopic dermatitis is caused by a complex interaction of immune dysregulation, epidermal gene mutations, and environmental factors that disrupts the epidermis causing intensely pruritic skin lesions. Repeated scratching triggers a self-perpetuating itch-scratch cycle, which can have a significant impact on the patient's quality of life. The American Academy of Dermatology has created simple diagnostic criteria based on symptoms and physical examination findings. Mai...

Date: June 15, 2020 Issue #:  1600Summary:  Atopic dermatitis (AD; also known as eczema) is frequently associated with other atopic disorders such as allergic rhinitis, asthma, and food allergy. It commonly presents in infancy and early childhood and has a relapsing course, often improving by adolescence, but sometimes persisting into (or first appearing in) adulthood or even old age.

Abstract Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by relapsing eczema and pruritus. Until the development of Dupilumab, a new monoclonal antibody targeting IL-4 and IL-13 receptors, the current treatment of severe cases was based on immunosuppressant agents. Our main goal was to build a case series of five patients with severe atopic dermatitis, who were using immunosuppressive drugs with significant adverse effects and only partially controlled AD, and compare their symptoms, SCORAD index, treatment regimens, total and specific IgE, and blood cell count before and after the intr...

This article assesses the potential of public social media data to give new insights into patient perspectives through a thematic analysis of a random sample of 400 tweets from 2019 matching the query, “my eczema.” Although the most common use of Twitter is to announce a flare-up, it is also used to express anger and discuss possible treatments. New themes not previously reported include the use of humor to discuss the condition and giving eczema agency: discussing it as if it had a will of its own. These may be defense strategies against the potential of eczema to strike at any time or the fear of negative rea...

CONCLUSIONS: We found lack of evidence to address our review question: for most of our interventions of interest, we found no eligible studies. The neurokinin 1 receptor (NK1R) antagonist serlopitant was the only intervention that we could assess. One study provided low-certainty evidence suggesting that serlopitant may reduce pruritus intensity when compared with placebo. We are uncertain of the effects of serlopitant on other outcomes, as certainty of the evidence is very low. More studies with larger sample sizes, focused on patients with CPUO, are needed. Healthcare professionals, patients, and other stakeholders may h...
