Active clinical trials for "Dermatitis, Atopic"

Sleep disturbance is a common complaint among patients with atopic dermatitis(AD). Melatonin may aid sleep and also has anti-inflammatory properties, and has been suggested in managing sleep disturbance in AD patients. However, there has been no large randomized controlled trials. Hence the objective of this double-blind randomized controlled study is to determine whether supplementing melatonin is effective in improving sleep problems in children with AD.

Atopic dermatitis (AD) is a chronic disease associated with intense itching, which affects most aspects of everyday life in the majority of patients. Acute inflammation and extensor/facial involvement is common in infants, whereas chronic inflammation increases in prevalence with age, as do localization to flexures. AD has a complex background characterized by immune activation, increased epidermal thickness in chronic diseased skin, and defective barrier function. In normal, healthy skin, the outer layer of the epidermis, the stratum corneum is made up flattened dead cells called corneocytes held together by a mixture of lipids and proteins. The stratum corneum and, in particular, the lipid layer are vital in providing a natural barrier function that locks water inside the skin and keeps allergens and irritants out. In people with AD, the barrier function is defective, which leads to dry skin. As the skin dries out, it cracks allowing allergens and irritants to penetrate. Mild AD can be controlled with emollients and topical medications. However, moderate to severe AD is extremely difficult to control and requires systemic treatment that is often unsatisfactory due to impracticality and lack of effectiveness. Only three therapeutic options exist for moderate to severe AD, including: 1) oral steroids 2) cyclosporine A (CsA), that is not widely used in the US as it is not FDA approved for AD and 3) ultraviolet phototherapy. Oral steroids and CsA treatments have major side effects and UV radiation therapy is highly inconvenient for patients. Several biologic medications, such as TNF-alpha inhibitors, are effective, convenient, and relatively safe therapies for psoriasis, but have thus far not shown efficacy in AD. Ustekinumab is a unique biologic medication that may specifically target AD. The investigators study will determine whether there is a reversal of the skin thickness and the immune pathways involved in the disease during treatment with Ustekinumab and what specific immune cells are involved. The investigators are also interested to understand how the clinical reversal of the disease will correlate with tissue reversal of the disease.

To verify of cetirizine dry syrup to ketotifen dry syrup in the change in the severity of pruritus of the treatment period.

To study the effect of supplementation of a hydrolyzed formula with probiotic bacteria on clinical and immunological parameters in infants with AD with and without CMA and to compare effectiveness of different strains of probiotics.

Pimecrolimus, which is an ascomycin derivative, is an anti-inflammatory non-steroidal agent. In this study, the long-term safety and efficacy of Pimecrolimus cream will be evaluated in Japanese pediatric patients with atopic dermatitis. This study is a 6-month extension study following core study. THIS STUDY IS NOT ENROLLING PATIENTS IN THE UNITED STATES

To evaluate the efficacy and safety of pimecrolimus cream 1% in its registered indication (treatment of patients > 3 months of age with mild to moderate atopic dermatitis) This study is not enrolling patients in the United States.

Atopic dermatitis is a common disease. Emollients and Elidel have both shown to be effective to treat this disease. The research question is, whether the effective component (Elidel) is better than the emollient to improve the skin function.

This study is not being conducted in the United States. To investigate the relative efficacy of pimecrolimus cream 1% applied twice daily (b.i.d.) versus once daily (o.d.) in preventing the progression to disease "relapse".

The primary purpose of this study is to investigate the safety of pimecrolimus cream 1% in the long-term treatment (up to 5 years) of atopic dermatitis (eczema) in patients less than 12 months of age compared to topical corticosteroids (TCS).

Atopic dermatitis, also called eczema, is characterized by redness, papulation (skin elevation) and pruritus (skin itching). The active ingredient of pimecrolimus inhibits the T-cell activation. These cells are involved in the inflammatory component of the disease. This study will test the safety of pimecrolimus Cream 1% with topical corticosteroid treatment (commonly used in eczema) in patients with severe atopic dermatitis.
