Filter by:Polymorphic light eruption (PLE) is a common photodermatosis with a high prevalence of approximately 11 to 21% in the population. Similar to lupus erythematosus (LE), an UV-inducible systemic autoimmune disease, PLE has a female preponderance with a mean onset in the second to third decade of life. PLE lesions are very itchy and typically appear on sun-exposed body sites in spring or early summer. The quality of life in patients with PLE is often severely disturbed, as evidenced by high levels of anxiety and depression. For prophylaxis besides conventional sunscreens, photo(chemo)therapy is effective in many cases, when administered over several weeks for hardening in early spring before the first natural sun exposure takes place. However, because prolonged treatment with UVB and/or photochemotherapy is potentially carcinogenic, the search for pathogenic mechanisms and new treatment options in PLE is ongoing. The exact pathogenesis of PLE is currently unknown but findings suggest an autoimmune-type background with resistance to UV-induced immune suppression and simultaneous immune reactions against skin photo-neoantigens. The investigators have recently found that PLE patients had significantly reduced 1,25-(OH)2-vitamin D3 serum levels (13-14ng/ml) compared to the normal population (>30ng/ml). In addition, the investigators were able to demonstrate in an intra-individual half-body trial that topical administration of an immunostimulatory 1,25-(OH)2-vitamin-D3 analogue calcipotriol reduced PLE symptoms in an experimental study. In the proposed randomized double-blinded placebo-controlled trial the investigators attempt to study the effect of oral vitamin D3 supplementation (2 x 40.000 IE, given orally two weeks apart) on PLE symptoms.
This study hopes to improve the investigators understanding of how the immune system acts in allergic contact dermatitis. In order to reach this goal, normal volunteers, who are suspected of having allergic contact dermatitis, will be patch tested for the fifteen most common allergens. Then, biopsies will be taken of the skin at the sites where the there is a positive reaction to the allergen. Also, small biopsies will be taken from an area that received a patch but no allergen and an area that did not receive a patch to serve as controls. In a second stage of the study, volunteers will receive patches with the allergen to which they demonstrated an allergic response. More biopsies will be taken, over three designated time points. The biopsied skin samples will then be studied in a laboratory.
Determine the mean time to itch relief from the start of treatment with topic methylprednisolone aceponate.
To evaluate the diagnostic performance (primary) and safety (secondary) of seven T.R.U.E. Test Panel 3.2 allergens: Gold sodium thiosulfate, Hydrocortisone-17-butyrate, Bacitracin, Parthenolide, Methyldibromoglutaronitrile, Disperse blue 106, and Bronopol in pediatric subjects 6-18 years of age with suspected contact dermatitis based on symptoms and clinical history.
Nickel contact dermatitis (eczema) is one of the most common allergic conditions affecting the skin. This is a study looking at potentially desensitizing nickel-allergic patients to their allergy using anti-inflammatory ointments applied to the skin (arm). Application of these ointments (ie. modified Vitamin D) has been shown to increase specific immune cells (T regulatory cells), which play a role in preventing immune activation and subsequently inflammation. The investigators propose use of topical anti-inflammatory agents (corticosteroids, modified Vitamin D, or both) may desensitize patients with nickel allergy.
Vulvar contact dermatitis (VCD) is a common problem presenting as vulvar pruritus, burning or irritation. Its estimated prevalence is 20-30% in vulvar clinics, but the prevalence in the general population is unknown. Contact dermatitis is an inflammation of the skin resulting from an external agent that acts as an irritant or as an allergen. The skin reaction may be acute, subacute or chronic, resulting from prolonged exposure to weak irritating substances. The most common form of VCD is irritant contact dermatitis, and it usually presents as vulvar itch. The causes that contribute to VCD are increased sensitivity of the vulvar skin to irritants compared to other body parts, decrease in the skin barrier function due to exposure to sweat, urine and vaginal discharge and constant friction of the vulvar area. In menopausal women, lack of estrogen contributes to tissue atrophy and thinning, and may increase the effect of irritants on the vulvar skin. One of the most common irritating substances that cause VCD is urine. The phenomenon of urine-induced VCD is known as" diaper rash" in babies, and it was also described in bedridden patients using diapers constantly. Women with urine incontinence (UI), a problem that its prevalence in women increases with aging, may use constantly panty liners or pads to prevent urine leakage. The urine is being absorbed in the pad, and the vulvar skin is continually exposed to urine. This can cause VCD, similar to diaper rash. The prevalence of this phenomenon in the general population is unknown. The patients complain of itch, burning or irritation of the vulvar skin, and on exam erythema, edema and irritated skin are found. As most patients do not connect between UI to their vulvar disorder, and as most care-givers do not ask routinely about UI, the vulvar symptoms are mistakenly attributed to yeast infection or other factors. As the cause to the vulvar complaints is not recognized, patients do not receive proper treatment that requires primary management of UI. The aim of the study is to evaluate the prevalence of VCD in women with UI and to recognize risk factors for UI induced VCD.
The purpose of the study is to assess the effect of a single dose of NI-0801 on the severity of nickel-induced allergic contact dermatitis.
Topical corticosteroids are largely used in dermatology. The major problem related to their use is that the same mechanisms underlying their therapeutic effects (antiinflammatory and antiproliferative) may lead to adverse events. Conditions sensitive to corticosteroids require formulations with mild to moderate potency while high-potency corticosteroids era required in less responsive conditions. The aim of the present study is to compare the safety and efficacy of prednisolone acetate 0.5% cream (mild-potency non-fluoridated corticosteroid) versus betamethasone valerate 0.1% cream (high-potency fluoridated corticosteroid) in the treatment of mild to moderate cortisosensitive dermatosis (atopic dermatitis, contact dermatitis, seborrheic dermatitis and psoriasis). The study hypothesis is that 0.5% prednisolone cream will be as effective as 0.1% betamethasone cream and will be an alternative option to treat corticosensitive dermatosis in body areas where the use of fluoridated corticosteroids is contraindicated, such as the face.
The objective of this study is to evaluate the efficacy of apremilast in patients with recalcitrant atopic or contact dermatitis.
This study will be a prospective, non-interventional, single arm and open label study, in patients with contact dermatitis requiring systemic steroid therapy with a purpose to obtain the real life effectiveness and tolerability of Medrol in treating contact dermatitis in Indian patients. Patients with contact dermatitis who have been prescribed for Medrol will be enrolled into the study and will be followed up for the resolution of symptoms
