Protection of the Skin Barrier Function in Inflammatory Disease.

[Protection of the Skin Barrier Function in Inflammatory Disease]. Yakugaku Zasshi. 2019;139(12):1553-1556 Authors: Ooi K Abstract The skin is the largest human organ, comprising the epidermis that is composed of epithelial tissue, the dermis composed of connective tissue, and the innermost subcutaneous tissue. Generally, skin conditions are due to aging and the influence of the external environment, but empirically patients with gastrointestinal diseases are more prone to pruritus and inflammation caused by dry skin. A decrease in the skin barrier function, involving immunocompetent mast cells and oxidative stress, was noted in indomethacin-induced small intestine inflammation, dextran sodium sulfate (DSS)-induced ulcerative colitis, and azoxymethane+DSS-induced colorectal cancer. A possible correlation was found to exist between inflammatory gastrointestinal diseases and the skin, and this correlation was investigated using a rheumatoid arthritis model as representative of inflammatory diseases. Similar to previously reported results, deterioration of the skin barrier function was observed, and new information was obtained by analyzing changes in inflammatory markers in the blood and skin tissues. Understanding the underlying mechanism of decreased skin barrier function will help in establishing effective prophylaxis and treatment methods and clarify the importance of crosstalk between organs. It will also help accelerate drug development. PMID: 3...

Selective estrogen receptor modulators (SERMs) are an increasingly important therapeutic modality that are used by clinicians on a daily basis. Unfortunately, clinicians have a limited understanding regarding the underlying mechanism(s) of how SERMs function and their increasingly useful role in the treatment of estrogen-responsive target tissues such as the breast, bone, vagina, uterine endometrium, and brain. This review will provide a basic understanding of our current knowledge of SERM pharmacodynamics and will highlight the clinical applications of Food and Drug Administration–approved SERMs in the treatment of ...

This study aimed to assess the symptom burden in the last 6 months of life in a real-world cohort. METHODS: Patients diagnosed with metastatic gynaecologic malignancies from 2016 to 2019 who completed the revised Edmonton Symptom Assessment System (ESASr) questionnaire within 6 months of death in a large Canadian province were identified. Patient-reported symptom scores were categorized as none to mild (0-3) and moderate to severe (4-10). Individual symptoms were subsequently grouped into physical, psychological, and total subscores. The severity of symptoms was further analyzed for any associations with age, time to d...

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

In this study, we identified 37 genus-level core bacteria from feces of 101 healthy mice with different ages, sexes, and mouse strains in three previous studies. They collectively represented nearly half of the total sequences, and predominantly included carbohydrate- and amino acids-metabolizing bacteria and immunomodulatory bacteria. Among them, Anaerostipes indwelt the gut of all healthy mice. Co-abundance analysis showed that these core genera were clustered into five groups (Group C1–C5), which were ecologically related. For example, the abundances of Group C2 including probiotics Bifidobacterium and Lactobacill...

This study showed a good safety and tolerability profile of the studied substance (Monteleone et al., 2012). Since TGFβ has been described to induce the profibrogenetic response of fibroblasts, patients were monitored for 6 months with intestinal ultrasonography, not showing signs of intestinal stenosis. Moreover, half of the patients maintained remission during the 6 months follow up period (Zorzi et al., 2012). Afterwards, a randomized, double-blind, phase 2 study was conducted in CD patients with inflammatory lesions in the terminal ileum and/or right colon, with steroid-dependence/resistance, randomized to three ...

Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...
