47 Clinical Trials for Various Conditions
Vigorous exercise can stress the body. Consuming special types of diet supplements may help the body recover better from exercise. This includes a bright red supplement called astaxanthin that is found in certain algae and causes the pink-red color in salmon. Astaxanthin is an antioxidant and may protect cells from damage and improve the way the immune system functions. The main purpose of this study is to determine if 4 weeks of consuming astaxanthin improves recovery from 2.25 hours of intensive running on a treadmill. This study will also measure whether or not astaxanthin supplementation improves skin health
The investigators are undertaking a clinical blister model with or without dietary supplementation with omega-3 fatty acids (i.e., Lovaza) to determine the role of specialized pro-resolving mediators - endogenous lipids converted from omega-3 fatty acid precursors including those in Lovaza - on inflammation parameters and their resolution.
A noticeably increasing number of patients are asking for naturally based extracts and ingredients as supplementary dermatologic remedies. Patients are seeking natural and cost-effective skin care alternatives in place of prescription medications and procedures.

The purpose of this study is to answer: how do inflammation and anti-inflammatory skin therapies work in the skin? Inflammation is a protective response from the body's immune system to injury, disease, or irritation. It is a process by which your body's white blood cells and the things they make protect you from infection from outside invaders such as bacteria and viruses.
This is a Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multiple-Site Study to Evaluate the Therapeutic Equivalence of a Generic Tacrolimus Ointment, 0.1% (Glenmark Pharmaceuticals, Ltd) to the Marketed Product Protopic® (tacrolimus) ointment, 0.1% (Astellas Pharma US, Inc.) in the Treatment of Moderate to Severe Atopic Dermatitis (AD).
This study will examine the production of proteins called chemokines in inflammatory skin reactions. It is thought that chemokines attract or recruit white blood cells from the blood stream into the skin when there is a skin injury or infection, causing inflammation. This study will examine chemokine production in induced inflammatory reactions to try to gain a better understanding of how white blood cells are attracted to inflamed areas of the body. Healthy normal volunteers between 33 and 60 years old may be eligible for this study if they 1) have no history of chronic skin disease; 2) are not allergic to eggs; and 3) do not tend to form large irregular scars after trauma to the skin from, for example, cuts, scratches and surgical incisions. Candidates will be asked a short series of questions and have a limited skin examination. Participants will have 10 ml (2 tablespoons) of blood drawn from an arm vein at the start and end of the 5-day study and undergo the following procedures: 1. Day 1 - Participants receive an injection in the right upper arm of mumps antigen (a protein commonly used to tests for immunization against mumps) and an injection of "vehicle" (saline plus the preservatives thimerosal, glycine and formaldehyde) in the left upper arm. 2. Day 3 - Participants who develop a swelling from the mumps antigen larger than 5 mm wide will receive another injection of antigen in the right arm and another injection of vehicle in the left arm. Those whose swelling is not greater than 5 mm will be excluded from the study at this point. 3. Day 5 - All four injection sites, plus another site on the left upper arm will be biopsied. For this procedure the five injection areas are numbed with a local anesthetic. A punch biopsy instrument that resembles a small cookie cutter (about one-third the diameter of a dime) is inserted about one-fifth of an inch deep into the skin and the tissue is removed. Two stitches are used to close the wound. Antibiotic and bandages are applied for 5 days. Nine days after the biopsy the participant returns to NIH for removal of the stitches. New molecular biology techniques will be used to measure changes in chemokine production in the biopsied tissue.
The primary objective of this study is to examine the influence of 4-weeks ingestion of TrueBroc®, (broccoli seed extract, BSE) with mustard seed powder (MSP) on improving skin health by evaluating skin physiological and biochemical parameters. This study will test the effect of BSE and MSP compared to placebo on skin health after 4 weeks supplementation. The study will employ a randomized, crossover design with subjects acting as their own controls.
This clinical trial aims to assess the effect of providing one avocado per day on skin health in comparison with a control group maintaining their habitual diets. Participants will be randomly assigned to one of two equally sized groups. Both groups will be instructed to continue to follow their habitual diet but the intervention group will receive one avocado per day. Participants will be followed for outcomes for a four-month period.
Sixty day single arm trial examining self-report and remote dermatology assessment of cosmetic skin health after daily 10-20 minute sessions with an infrared light therapy device (the Joovv Mini)
A noticeably increasing number of patients are asking for naturally based extracts and ingredients as supplementary dermatologic remedies. Patients are seeking natural and cost-effective skin care alternatives in place of prescription medications and procedures. This study will isolate the effects of oral turmeric and assess a combination tablet that includes turmeric on sebum production in healthy subjects.
The purpose of this study is to determine the efficacy of pomegranate extract and pomegranate juice on skin inflammation and aging. The information gained from this study may lead to the development of a pomegranate product that can decrease the effects of aging, inflammation and harmful bacteria on the skin. In this study, two pomegranate products (extract and juice) will be compared with a placebo, a study product that looks like pomegranate extract, but contains no active ingredients.
This is a randomized, investigator-blinded, self-controlled pilot study of the physiologic response to topical moisturizers among older adults with dry skin. The overarching hypothesis is that skin barrier decline is an important source of chronic inflammation, and that skin barrier restoration with moisturizers can reduce serum biomarkers of inflammation. The primary objective is to determine the feasibility for a larger trial, and the secondary objectives are to determine the extent to which measures of serum inflammation, skin barrier function, and the skin microbiome change in response to moisturizers. Participants will be asked to apply one of two topical moisturizers that are widely available over the counter in the US (Vaseline® 100% pure petroleum jelly or CeraVe® moisturizing cream) once daily for 4 weeks to the front of the torso, buttocks, arms, and legs. Subjects will act as their own control (i.e. they will be asked to apply the study moisturizer they are randomized to for one intervention period (4 weeks) and not to apply topical moisturizers for the other 4- week intervention period). Participants will be randomized in a 1:1:1:1 ratio to one of 4 treatment groups: i. no intervention then CeraVe; ii. CeraVe then no intervention; iii. no intervention then Vaseline; iv. Vaseline then no intervention. At each visit (baseline, week 4, and week 8), participants will undergo skin barrier testing, skin microbiome sampling, and phlebotomy to measure serum inflammatory markers.
This trial will assess the effectiveness of the Aria Trio Complete Facial system in being able to reduce blemishes, lines, and wrinkles. This skincare system that has three different functions in association with three unique serums. It is hypothesized that this customized skincare system will improve skin quality, reduce wrinkles, and reduce other skin related issues.
This research study is examining a preventive skin care regimen for children diagnosed with a brain tumor and receiving anti-cancer therapy with a MEK, Pan-RAF, or BRAF inhibitor.
The anti-oxidative and anti-inflammatory effects of polyphenolic compounds of almonds have been reported in limited animal studies and may have the potential to improve skin radiance. However, the skin related beneficial properties of almonds have not been investigated in humans. This study will examine the effects of almond consumption on human skin radiance in Asian women as a pilot.
The objective is to determine, in a small number of participants, the protective effects of UV-induced skin erythema (reddening or "sunburn") following oral administration of sulforaphane, curcumin, or a combination of the two plant (diet)-based supplements. The investigators will be using the over-the-counter nutritional supplements Crucera-SGS and Meriva-SF to deliver the biologically stable sulforaphane precursor and a highly bioavailable formulation of curcumin. Volunteers will be challenged with UV irradiation at 2-times the minimum erythematous dose (M.E.D.) on discrete 2 cm diameter circles on the upper buttocks. Skin redness will be monitored daily using a chromometer. Biomarkers will then be evaluated in blood, urine, and skin biopsies.
The study is a Phase 2, multi-center, randomized, double-blind, placebo-controlled study to evaluate the effects of tibulizumab over 16 weeks (Period 1) in adults with hidradenitis suppurativa, followed by a 16-week open-label extension period in which all participants will receive tibulizumab (Period 2)
The purpose of this study is to evaluate how supplementation will alter the skin and the gut barrier and inflammation in those with rosacea.
The purpose of this study is to better understand the underlying mechanisms associated with elevated cardiovascular disease risk in women with endometriosis, and to measure the effectiveness of emerging endometriosis treatments on outcomes specific to cardiovascular dysfunction. Epidemiologic data demonstrate a clear association between endometriosis, reproductive risk factors, inflammation and cardiovascular (CV) risk. Circulating factors, low-density lipoprotein (LDL) and oxidized LDL (oxLDL), are two of many biomarkers of cardiovascular and inflammatory disease of endometriosis. An important signaling mechanism through which circulating LDL and oxLDL act is the lectin-like oxidized LDL receptor (LOX-1). LOX-1 signal transduction functionally results in pronounced endothelial dysfunction, a hallmark of CV. The investigators hypothesis that one factor mediating the elevated risk of cardiovascular disease in endometriosis is systemic inflammation and activation of LOX-1 receptor mechanisms.
People with Down syndrome (DS) display widespread immune dysregulation, including several immune skin conditions. This study hypothesizes that pharmacological inhibition of the increased interferon (IFN) signaling seen in DS is safe and could improve associated skin conditions. The study evaluates the safety and efficacy treatment with Tofacitinib, an FDA-approved drug known to block IFN signaling, in adolescents and adults with DS and an autoimmune and/or autoinflammatory skin condition. Investigators will also measure the impact of interferon inhibition on a variety of molecular markers, as well as the cognitive abilities and quality of life of participants.
The objective of this exploratory study is to gain an understanding of cutaneous and systemic inflammation and how restoration of the skin barrier through the use of moisturizer may restore the skin barrier function and reduce systemic inflammation in elderly humans compared to the young. The exploratory study will consist of three visits per subject. Subjects will be instructed to apply a moisturizer (Vanicream Moisturizing Skin Cream) over the entire skin surface from the neck down twice daily for up to 30 days.
This study will determine the effects of beneficial compounds of plant foods, such as pomegranate on cardiovascular health, skin inflammation and aging. This will be tested by asking healthy males to eat a high fat ground beef patty with 8oz. pomegranate juice or 8oz placebo (a study product that looks like pomegranate juice, but contains no active ingredients) and then measuring blood vessel dilation (endothelial function) by blood flow. The investigators also will measure the amount of Nitric Oxide (NO) in blood and urine samples and sugar and insulin in blood. In addition, a Cutometer, a device that measures the elasticity of the skin, will be used to obtain measurements of skin inflammation and aging. Healthy men have been chosen for this study because eating high fat hamburger patties can easily mimic in them the condition that causes atherosclerosis. The results from this study may help to explain how high fat foods can be harmful to the body and how beneficial plant foods can have on cardiovascular function and the skin.
We are looking to see how the addition of nitrosomonas alters the presence of nitrolipids and inflammatory cytokines on the skin.
The purpose of this study is to determine the effect of topical aminocaproic acid on the immune system by assessing the levels of antimicrobial peptides in the skin of patients with rosacea. It is hypothesized that aminocaproic acid applied topically will alter the body's immune system in patients with rosacea by inhibiting activation of antimicrobial peptides.
The purpose of this Phase 3 trial is to evaluate the efficacy, safety, and tolerability of oritavancin in ABSSSIs, including those caused by MRSA and to evaluate the potential economic benefit of oritavancin administered as a single 1200 mg IV dose.
The purpose of this Phase 3 trial was to evaluate the efficacy, safety, and tolerability of oritavancin in acute bacterial skin and skin structure infections (ABSSSIs), including those caused by methicillin-resistant staphylococcus aureus (MRSA), and to evaluate the potential economic benefit of oritavancin administered as a single 1200-milligram (mg) intravenous (IV) dose.
This study will evaluate the effects of a protein called secretory leukocyte protease inhibitor (SLPI), on skin wound healing. Produced naturally by the body, SLPI modifies levels of elastase, a substance that breaks down the skin. Older people are at greater risk of impaired wound healing, with increased elastase activity and inflammation. In addition, men heal more slowly than women. Delayed healing is associated with infection and pain and can lead to the development of chronic non-healing skin wounds. Healthy men and women between 60 and 80 years old who wish to participate in this study will have a brief history and physical evaluation to determine their eligibility. Those enrolled will be randomly assigned to receive a gel form of SLPI applied topically (on the skin surface) to a skin wound or a placebo (a look-alike gel with no active ingredient). Participants will undergo the following procedures: First visit - The skin will be numbed with a local anesthetic and two small (4 mm) wounds (about the size of a pencil eraser) made in each upper arm. The drug or placebo will be applied to the wound and gauze placed over it. Two blood samples (20 ml and 7 ml) will be drawn an hour apart to determine blood levels of SLPI. Second visit - The day after the first visit, the wound dressing will be removed and the participant will be evaluated for pain at the wound site, allergic reactions or infection. A blood sample (7 ml) will be taken. Third visit - The wounds will be examined and photographed to evaluate healing. In addition, the strength of the wound may be assessed by means of a vacuum system placed on the skin. (This may cause a tingling sensation over the wound.) A piece of all four wounds will be removed after the skin has been numbed and a dressing applied. Fourth visit - The wounds will be examined for healing and the dressing removed.
The primary objective of this study is to compare the incidence of postoperative hypergranulation tissue formation after gastrostomy tube placement among children randomized to one of three treatments, in addition to measuring tube dislodgements and rates of resource utilization for complications.
The study aims to compare outcomes in patient comfort, cosmetic appearance, and complication rates between sutures and staples in high tension areas for closures of skin cancers excised in a dermatology clinic.
