11 Clinical Trials for Various Conditions
This was a placebo-controlled double-blinded trial to compare effects of 2% IDL lotion to placebo in female subjects with dry skin. Primary endpoints were skin hydration (NovaMeter) and transepidermal water loss (VapoMeter).
To evaluate the ability of 2 Helioblock SX Cream formulations to moisturize skin using capacitance and transepidermal water loss methodology
Few studies have assessed the effects of Triphala and Rubia Cordifolia from a skin biophysical perspective. Here, we aim to understand how these herbs can modulate the skin's barrier properties and the gut microbiome.
This study will explore potential links between atopic dermatitis and food allergy. This information will be useful to determine atopic dermatitis and food allergy share unique biochemical or genetic identifiers useful for diagnosing and treatments in the future. This is a mechanistic study consisting of obtaining blood and skin samples from participants at baseline. Individuals may also undergo a clinically indicated oral food challenge and have blood and skin samples collected at various times during the oral food challenge. This study will create a molecular map of the pathology of atopic dermatitis and food allergy. This information will be deployed to evaluate the hypothesis that atopic dermatitis and food allergy share unique genetic transcriptional signals in which the study team can then further analyze pathological pathways and cell types.
Transepidermal Water Loss (TEWL) measurements are a valuable tool to determine the integrity of a person's skin barrier. In patients with skin conditions, like atopic dermatitis, skin barrier can be disrupted or weakened, leading to a more severe phenotype and disease characteristics. There are several commercially available TEWL measuring devices, including the Aquaflux AF200 and the GPSkin Barrier Pro. This study is a pilot study to determine if these two devices produce similar readings for TEWL/skin barrier on patients with and without atopic dematitis (AD). The research team would like to investigate whether these devices are comparable for initial TEWL readings as well as after several rounds of tape strips have been collected from the skin. Tape strips are small circular adhesives, much like tape, that remove the very outermost layers of skin cells. It will be important to know if both of these devices provide correlative values for TEWL once the outermost layers of the skin have been removed by tape stripping.
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.
Background: Atopic dermatitis (AD) is a skin disease also called eczema. It is common in children and sometimes gets better on its own. However, chronic AD may cause asthma, food allergies, eye infections, and sleep problems. The cause of AD might be related to bacteria that live on the skin. Researchers want to see if introducing bacteria, R mucosa, from healthy skin onto the skin of someone with AD helps treat the disease. Objective: To test the safety and activity of R mucosa for treating AD. Eligibility: Part 1: People ages 18 and older with AD Part 2: Children ages 3-17 with AD Design: Participants will be screened with: Medical history Physical exam Examination of their AD Blood and urine tests At the baseline visit, participants will have blood tests and photos taken of their skin. They will get a supply of R mucosa and a memory aid to track their doses and record how they are feeling. Part 2 participants guardians will complete questionnaires about their child s AD. Part 1 participants will spray R mucosa on their arm twice per week for 6 weeks. Part 2 guardians will spray it on their child s arm twice per week for 16 weeks. Participants will have follow-up visits to repeat some baseline tests and review their memory aid: Part 1: Six weeks after the baseline visit Part 2: Four times over 16 weeks; then 2 or 3 times for 1 year Participants will be called or emailed to discuss how they are feeling: Part 1: About 30 days after their last visit Part 2: About every 10 days between visits
While the repair of the epidermal barrier in atopic dermatitis is of major importance in the treatment of atopic dermatitis, most of the vehicles used may actually cause a worsening of an impaired epidermal barrier. Hydrogel vehicle is anecdotally known to be moisturizing and hydrating.This study will compare the use of Hydrogel vehicle and Eucerin Lotion in maintaining the epidermal barrier in subjects with atopic dermatitis.
The purpose of this research study is to discover whether instruments widely used in skin research can be used to measure wound healing in split thickness skin graft donor sites and whether these instruments can detect differences in healing when two different dressing products are used.
This work is based on DFU patients, seeks to conduct a fully powered clinical study testing i) If DFU with a history of biofilm infection closes with deficient barrier function. ii) whether such functionally deficient wound closure, manifested as high TEWL, is associated with greater wound recurrence. The primary parent study will also address molecular mechanisms implicated in biofilm-induced loss of skin epithelial barrier integrity in DFU patients.
This is a multicenter study of patients with diabetic foot ulcers (DFU) to develop and validate potential tissue-based biomarkers that predict DFU wound recurrence. Trans-epidermal water loss (TEWL) will be measured on the closed wound site and a location similar to the wound site (reference site). Participants will be enrolled within two weeks after closure of their DFU. Complete wound healing will be verified at a second visit two weeks later and this visit will start the 16 week timeline where participants will be followed weekly by phone until the earliest of DFU wound recurrence or 16 weeks. Participants who experience a DFU wound recurrence and a subset of participants who do not experience a DFU wound recurrence by week 16 will be asked to attend one final visit.
