The phenotype of systemic lupus erythematosus as a factor in rational therapy choosing

Systemic lupus erythematosus (SLE) is characterized by a variety of clinical manifestations, which are defined as separate phenotypes of the disease. Despite the universality of immunopathological reactions, which are based on the formation of anti-nuclear antibodies and antibodies to native DNA, the spectrum and severity of immunological disorders in individual phenotypes are different. The role of type I interferons (IFN) in the SLE pathogenesis has now been proven. Hypersecretion of IFN-α and IFN-β leads to the production of antibodies against the components of the cell nucleus through activation of the native and adaptive immunity system. The current treatment strategy provides for achieving remission or low activity with immunosuppressants, including selective ones, such as biological agents. According to the updated international recommendations, anifrolumab, monoclonal antibodies against type I IFN, which has demonstrated high efficacy in the treatment of SLE with skin-mucous and joint lesions., can be used for the treatment of SLE along with rituximab and belimumab. The article presents our own clinical observation on the analysis of the effecacy and safety of anifrolumab in the treatment of a young patient with high-activity SLE and pronounced skin manifestations. It was shown that after the first injections of the drug, there was a rapid dynamics of skin and joint syndrome, the activity of SLE decreased from maximum to minimum according to the SELENA-SLEDAI index. The results obtained confirm the rationale of including anifrolumab in the treatment regimen in cases of insufficient previous therapy.
