Scratching the skin primes the gut for allergic reactions to food, mouse study suggests
(NIH/National Institute of Allergy and Infectious Diseases) Scratching the skin triggers a series of immune responses culminating in an increased number of activated mast cells -- immune cells involved in allergic reactions -- in the small intestine, according to research conducted in mice. This newly identified skin-gut communication helps illuminate the relationship between food allergy and atopic dermatitis (a type of eczema), a disease characterized by dry, itchy skin. The NIAID-supported study was led by researchers at Boston Children's Hospital.
Conclusion: In patients with hypertension, a 4-week treatment with firibastat, tended to decrease daytime SBP relative to placebo. Firibastat did not modify the activity of the systemic renin–angiotensin system These results have justified designing a larger, powered trial of longer duration to fully assess its safety and effectiveness. Clinical trial registration: http://www.clinicaltrials.gov. NCT02322450.
Conclusion: Ce6-mediated PDT might be used as a potent therapeutics for AD via restoring Th1/Th2 balance and reducing over expressed immune cells.
ConclusionModerate-to-severe AD is associated with significant decrements of health utility in the US population. These data illustrate the heavy societal burden of moderate and severe AD and provide important insight for prioritization of resource allocation and cost-effectiveness research.
CONCLUSIONS: Evidence suggests that, compared with no probiotic, currently available probiotic strains probably make little or no difference in improving patient-rated eczema symptoms. Probiotics may make little or no difference in QoL for people with eczema nor in investigator-rated eczema severity score (combined with participant scoring for eczema symptoms of itch and sleep loss); for the latter, the observed effect was small and of uncertain clinical significance. Therefore, use of probiotics for the treatment of eczema is currently not evidence-based. This update found no evidence of increased adverse effects with pro...
ConclusionsSelf-reported adult-onset AD is common and has distinct phenotypes with lesional predilection for the hands and/or head/neck.
Atopic dermatitis (AD) is associated with intense itch and loss of sleep in early life and with food allergy and asthma, in later life. The early origins of AD are incompletely understood but involve a complex interplay between the skin barrier, immune dysregulation, and the cutaneous microbiome. Eczema has a close relationship with Staphylococcus aureus colonization, which is associated with flares of AD. However, it was not known whether S aureus colonization preceded eczema or eczema followed S aureus colonization.

Publication date: Available online 13 September 2015 Source:The Lancet Author(s): Stephan Weidinger, Natalija Novak Atopic dermatitis (also known as atopic eczema) is a chronic inflammatory skin disease that is characterised by intense itching and recurrent eczematous lesions. Although it most often starts in infancy and affects two of ten children, it is also highly prevalent in adults. It is the leading non-fatal health burden attributable to skin diseases, inflicts a substantial psychosocial burden on patients and their relatives, and increases the risk of food allergy, asthma, allergic rhinitis, other immune-mediat...
Conclusion: The patients' histories and findings indicate the possibility of percutaneous sensitization through occupational exposure to parvalbumin, leading to food allergy.Case Rep Dermatol 2015;7:227-232
