Atopic dermatitis is an inflammatory, pruritic, recurrent chronic skin disease often associated with a personal or family history of allergic diseases such as bronchial asthma, allergic rhinitis conjunctivitis. A comprehensive, long-term treatment plan should be adopted. 1. Avoid allergens and aggravating factors. For example, avoid smoking, using vacuum cleaners, insecticides, using covers, wearing soft clothes, using moisturizers in dry season, breastfeeding for at least 4 months, vaccination at rash-free places, residence ventilation but closing windows in pollen season, mopping with sponge, not using carpets, not using toys containing hair, not keeping pets, etc. 2. Health education and psychological treatment are important to achieve good results. Adequate use of moisturizers is an important basic treatment. 3.Topical glucocorticoids (TCS, Topical glucocorticoids) is the first-line therapy for AD. Topical calcineurin inhibitors (TCIs) are safe and effective. 4, TCS or TCI intermittent treatment plus adequate use of emollients can effectively reduce the disease and delay relapse. 5. For AD patients with severe pruritus, the use of first-generation antihistamines with sedative effects is recommended. 6. AD patients with impaired skin barrier are prone to secondary infections, most commonly Staphylococcus aureus infection, and other pathogens such as streptococci and fungi. For patients with concomitant infections, antibacterial agents or antifungal drugs should be applied systemically or topically. 7.Ultraviolet (UV) light therapy is an effective second-line treatment option for AD. Phototherapy is preceded by topical glucocorticoids and emollients. The general treatment is 3-5 times/week for 6-12 weeks.
