Abstract: Pemphigus vulgaris is a kind of autoimmune skin disease involving the skin and mucous membranes and characterized by generalized blisters.Medicines exert their therapeutic effect on pemphigus vulgaris mainly by suppressing the immune system and reducing the production of related specific antibodies.At present,glucocorticoids still serve as the first-choice routine treatment.Rituximab,a kind of anti-CD20 monoclonal antibody,has shown satisfactory therapeutic effects in the adjuvant treatment of pemphigus vulgaris in recent years.However,the treatment with rituximab can cause severe transfusion-related reactions and increase the risk of infection.Because of the disadvantages of high price,long treatment duration,high recurrence risk and drug resistance,the clinical application of rituximab in the treatment of pemphigus vulgaris has been reduced.The new generation of anti-CD20 monoclonal antibody can overcome adverse reactions induced by rituximab treatment,improve medication approaches and reduce the treatment duration,so it has been gradually applied to the treatment of pemphigus vulgaris.In addition,new research results can provide more treatment options for patients with pemphigus vulgaris.
