Filter by:Irritant contact dermatitis induced by sodium lauryl sulphate (SLS) is often used as a model for testing efficacy of various topical preparations. Aforementioned model is standardized and described in guidelines, but it is not explicitly stated where the irritation should be induced. Published clinical trials usually irritate volar aspect of forearms or upper back. Also, lower back and dorsal aspect of forearm are sometimes used. Skin parameters vary depending on anatomic location of measured skin. There is a difference in stratum corneum thickness, hydration and transepidermal water loss across different locations, including between volar forearm and upper back. Furthermore, regional difference in skin response to irritation by tape stripping and benzalkonium chloride were observed. Such differences are also possible in SLS irritation model. One study has shown higher, but not statistically significant, response of back in comparison to forearms, but it had a very small sample size (n=9). Moreover, there are regional variations of topical preparations absorption. Hydrocortisone had 1,7 times higher absorption when applied to upper back in comparison to forearms. Those variations could be explained by different corneocyte size and number of their layers between back and hands. Skin baseline properties and response to irritation seem to be dependent on anatomic position. Those differences could mean different response to treatment. Since published trials only tested efficacy of various preparations on one anatomic location, it is possible their results would be different if tested on other body parts. It could limit validity and usefulness of conducted trials. The aim of this study is to determine if there are regional differences of skin response to irritation and emollient cream treatment in irritant contact dermatitis model.
This trial will test the feasibility of various imaging devices to detect local skin inflammation prior to clinical manifestation.
This study evaluates the potential anti-inflammatory effects of inorganic dietary nitrate in a model of acute inflammation relevant to cardiovascular disease (CVD). Green leafy vegetables contain large amounts of inorganic nitrate, and research suggests that this nitrate has beneficial effects on the heart and blood vessels. The Ahluwalia Group have shown anti-inflammatory benefits of inorganic nitrate in pre-clinical models of CVD, early mechanistic studies in healthy volunteers, and in patients with hypertension, hypercholesterolaemia and those suffering acute heart attacks that translate to cardiovascular benefits. Understanding the mechanism of how this is achieved may open new therapeutic options in CVD. The Investigators therefore wish to explore whether inorganic nitrate might alter inflammatory responses using a blister-model of acute skin inflammation. This study is a randomised control trial with parallel limbs where half of patients receive nitrate-rich beetroot juice, and the other half a nitrate-deplete placebo beetroot juice.
This is a randomized, double-blind, vehicle-controlled study to evaluate the safety and efficacy of ALX-101 Gel 1.5% and 5% and a matching ALX-101 Gel Vehicle when applied topically twice daily for 42 days to adult and adolescent subjects with moderate atopic dermatitis.
This is a prospective, single center, clinical mechanistic pilot clinical research study. Participants will not receive any investigational agent. The investigators will examine whether children with atopic dermatitis (AD) and food allergy have a different skin barrier, microbiome, epidermal transcriptome, and epidermal lipid composition than children with AD and no food allergy and non-atopic (NA) children. Participation involves a single study visit.
Primary objective: To evaluate the efficacy of tralokinumab compared with placebo in treating moderate to severe atopic dermatitis (AD). Secondary objectives: To evaluate the efficacy of tralokinumab on severity and extent of AD, itch, and health related quality of life compared with placebo. Maintenance objective: To evaluate maintenance of effect with continued tralokinumab dosing up to 52 weeks compared to placebo for subjects achieving clinical response at Week 16.
This is an investigator-initiated, single-center, prospective, randomized, double-blind, interventional phase IIb study. Forty patients with clinically and histologically confirmed nummular eczema will be enrolled according to inclusion and exclusion criteria. Patients will be included after written informed consent is obtained. Prior to randomization, average application rate of class II topical steroids per day will be measured for 4 weeks. Subsequently, patients will be randomized in a 1:1 ratio into one arm to receive Apremilast 30 mg BID (following titration phase) for 16 weeks or a second arm receiving identically matching placebo for 16 weeks. From beginning of week 17, all patients will start an open-label treatment with Apremilast 30 mg BID until week 32. Concomitant use of topical steroids (class II) is allowed during the study. During the treatment period both placebo and Apremilast will be applied p.o. from week 0 until week 32.
Unlike healthy control skin, the skin of patients with atopic dermatitis (AD) is frequently colonized by Staphylococcus aureus (S. aureus), putting these patients at increased risk of S. aureus skin infections. In addition, research in the investigator's lab has shown that these patients have fewer protective antimicrobial Staphylococcal species such as Staphylococcal epidermidis (S. epidermidis) that are known to produce antimicrobial peptides that play a role in protecting the skin from invading pathogens. In this study, the investigator will attempt to decrease S. aureus colonization and increase colonization of protective Staph species in AD patients. First the investigator will capture the bacteria on subjects' skin. Next the investigator will selectively grow the subject's antimicrobial Staphylococcal colonies and place them into a base moisturizer. The moisturizer plus bacteria will be applied to one of the subject's arms for one week. Some subjects will receive placebo, which is the moisturizer alone (without bacteria). The investigator will then swab the arms at specified time points during and after the one week application in order to determine whether the S. aureus abundance was affected by the application of the transplanted bacteria.
This Study Evaluate the efficacy of the subministration of fermented rice flour (7 g/day) on the clinical course of patients with moderate or severe Atopic Dermatitis, in terms of a reduction in the SCORAD score, during the study period and four weeks after the suspension of the treatment.
The purpose of this study is to examine the safety and effectiveness of a new therapy, commensal lotion containing infection fighting bacteria, on decreasing or eliminating the infection causing bacteria found on the skin of Atopic Dermatitis (AD) patients.
