Abstract
Description
Technical Field
[0001] The present application relates to a composition for treating skin inflammation and belongs to the technical field of drugs for skin inflammation. Background Art
[0002] Human milk oligosaccharides (HMOs) are a unique mixture of oligosaccharides present in human milk. Among them, various HMOs such as 2'-fucosyllactose (2'-FL), 3-fucosyllactose (3-FL), and lacto-N-tetraose (LNT) have been found to exhibit excellent biological functions in aspects such as gastrointestinal barrier, enhancing immunity, anti-inflammation, and promoting brain nerve development.
[0003] Dermatitis is a general term for skin inflammatory disorders caused by various internal and external infectious or non-infectious factors. It is an inflammatory skin disease caused by multiple factors, and the etiology may be related to allergies, infections, drugs, insect bites, physical factors, etc. The clinical manifestations are diverse, and the skin lesions are polymorphic, including papulovesicles, blisters, erythema, scales, erosions, ulcers, etc. Patients may also experience discomfort such as itching, burning, and pain. Among them, atopic dermatitis (AD, also known as eczema) is a chronic / recurrent inflammatory skin disease, characterized by symptoms including intense itching (e.g., severe itching) and squamous and dry eczema-like lesions. AD usually begins in childhood before the age of 5 and may persist into adulthood.
[0004] The treatment methods for dermatitis include topical lotions and moisturizers, topical corticosteroid ointments, creams, etc. Since eczema is prone to recurrence, many patients will develop moderate to severe dermatitis, and some patients will develop resistance to topical corticosteroids. The severe itching caused by recurrence has brought confusion to the lives of patients and their families. Therefore, new compositions for treating and / or preventing dermatitis are needed.
