Summary

This is a multicenter observational retrospective-prospective study consisting of retrospective and prospective phases. Trial will include 2 visits for obtaining the patient's demographic and clinical data: the 1st is retrospective and the 2nd is prospective. The study will involve approximately 50 sites of the Russian Federation; in each site about 20 patients will be recruited. The total planned size of study population will be approximately 1000 patients enrolled to the retrospective phase of the study, from which \~ 600 patients will be enrolled to the prospective phase.

Detailed description

Systemic lupus erythematosus (SLE) is a systemic autoimmune rheumatic disease with variable clinical manifestations and an unpredictable course, affecting any organs or systems, which quite often develops over several months or years, with persistent or, conversely, rapidly changing clinical manifestations, an undulating course, alternating remissions and flares. Currently, in Russia there is no exact data on the number of patients with active moderate to severe SLE in the population, since there is no unified system for regular monitoring of patients with SLE in the country. The systematic information about complications and comorbidities, about the treatment approaches and their effectiveness in the Russian population is also absent. The Russian Federation consists of 85 regions with a total population of more than 145 million people. The regions differ in ethnic composition, age, gender, climate, ecology, economic level, prevalence of SLE in general and moderate to severe SLE in particular. Thus, there is a need to perform a large-scale observational study in regions of the country with a sufficient size of population to obtain information on moderate to severe SLE epidemiology, clinical and demographic characteristics, to describe main clinical outcomes and evaluate existing associations between observed treatment patterns and clinical outcomes in real clinical practice. Trial will include 2 visits for obtaining the patient's demographic and clinical data: the 1st is retrospective and the 2nd is prospective. To allow wide data coverage the study will involve approximately 50 sites of Russian Federation; in each site about 20 patients will be recruited. Overall expected duration of the study (from the first patient inclusion to the last patient last visit) is about 13 months or until 1000 patients will be included in the retrospective phase and \~ 600 patients - in the prospective phase This observational study does not imply any intervention into a routine clinical practice, including choice of treatment modality or special methods of investigation.
