The treatment of skin immune diseases is one of the most successful cases in immunological translational medicine. Previously, the treatment of skin immune diseases was mainly achieved through the accidental discovery of drugs or therapies, which often had poor efficacy and certain toxicity in long-term treatment. With the application of biological agents, more and more patients have achieved the treatment goal of completely or almost completely clearing skin lesions and itching. We still have many questions regarding the pharmaceutical mechanisms of biologics, rational and safe use of drugs, long-term patient management, early intervention, and other aspects. In order to promote the development of skin immune diseases, psoriasis, urticaria and other fields, improve the level of precision diagnosis and treatment, use biological agents reasonably and safely, manage chronic diseases throughout the process, and reduce the disease burden of patients, the "Fourth Academic Conference on Standardized Diagnosis and Treatment of Skin Immune Diseases" hosted by Chengdu High tech Medical Association was held online on September 16, 2024. Representatives attending the conference expressed their great benefits and hoped to participate in similar conferences in the future.
