Filter by: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 Staphylococcal species such as Staphylococcus 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 study team will attempt to decrease S. aureus colonization and increase colonization by protective Staph species in AD patients by first culturing the bacteria on subjects' lesional AD skin. The study team will selectively grow the subject's protective Staph colonies and place them into a moisturizer. The first part of the study will determine the half-life of the bacteria-containing moisturizer. The bacteria-containing moisturizer will be applied to a subject's arm, and the subject will return at four different time points over the next three days for skin swabs of the arm that will be used to determine the amount and type of bacteria on the arm at those time points. In the second part of the study, the subject will apply moisturizer containing his own antimicrobial bacteria to one of his arms for a total of 6 times at a frequency determined by the half-life, which will be computed at the end of the first part of this experiment. The subject will return prior to the 7th application time point for skin swabs of the arm to ensure that there are still viable bacteria from the moisturizer present on the arm. In the third part of the study, each subject will receive both moisturizer as well as moisturizer plus his own antimicrobial bacteria. The subject will apply the moisturizer to one arm and the moisturizer plus bacteria to the other arm daily for a total of 15 days. Subjects will return to the clinic every 5 days for skin swabs and clinical evaluations. If the moisturizer containing bacteria is able to decrease the S. aureus colonization on subject's arms, the study team hypothesizes that subjects will have improvement of their AD symptoms.
The purpose of this study is to determine whether the dosage of 0.1% tacrolimus ointment applied on unit area of eczema influence the efficacy of treatment.
The main objectives of the study are: To determine if RNA recovery from tape harvesting allows for the identification of a disease gene signature (e.g., interferon [IFN] signature for lupus) or other biomarkers that may differentiate affected from normal or unaffected skin; To determine if the lupus gene signature is differentially expressed in the epidermis from active discoid lupus erythematosus (DLE) or subacute cutaneous lupus erythematosus (SCLE) lesions when compared with unaffected skin from the same participants and from the skin of healthy volunteers (HVs); To determine if the atopic dermatitis (AD) gene signature is differentially expressed in the epidermis from active AD lesions when compared with unaffected skin from the same participants and from the skin of HVs; and To correlate the levels of transcripts of targeted genes in the skin by tape harvesting with those obtained from the blood.
The study objective is to evaluate whether a specific prebiotic (GOS/PDX) may have an effect in preventing atopic dermatitis, food allergy, intestinal and/or respiratory infections in infants at risk of atopy. In infants with dermatitis, the hypothesis will be tested that prebiotics reduce the severity of the disease.
The primary objective of this trial is to assess the efficacy of the consumption of heat-treated Lactobacillus paracasei (GM080) on atopic dermatitis as compared to a placebo treatment.
The purpose of this study is to validate a left-right design with respect to detecting a difference in efficacy after 3 weeks of treatment between an active treatment and a vehicle in adults with mild to moderate atopic dermatitis
The aim of this study is to investigate the mechanisms behind the immune dysfunction that occurs in atopic eczema (or atopic dermatitis).
Aim of this study is to use the major allergen 1 of birch-tree pollen (Bet v 1, Betula verrucosa, synonymous Betula pendula), to investigate the contribution of immunoglobulin E (IgE)- versus non-IgE-mediated mechanisms to chronic skin inflammation in atopic dermatitis patients.
The study is initiated in the indication of atopic dermatitis to study the impact of placebo in the treatment of pruritus. Classical conditioning and expectation via instructions/anticipation maintain the effect of placebo.
This is a multicenter, double-blind, vehicle-control study of 0.05% and 0.2% E6005 ointment. Pediatric subjects with atopic dermatitis (AD) will be grouped into two; an elder group (childhood - adolescent: 7 to 15 years of age) and a younger group (children: 2 to 6 years of age) according to the sequential cohorts by confirming the safety.
