title: [Current views on etiopathogenesis of systemic lupus erythematosus].
abstract: The article is a review of information concerning etiopathogenesis of systemic lupus erythematosus (SLE). Due to the risk of serious complications, including death, the clarification of etiology could result in substantial improvement or even complete cure of the disease. Progress in scientific research of observed disorder mechanisms together with implementation of appropriate therapies contributed to a higher detection rate, improved course and decreased mortality in SLE. However, there are still many doubts, which legitimate the need of further research. A significant role in development of the disease and further exacerbations is played by environmental factors. Therefore, decreased exposure to UV light, female sex hormone and microbial antigens is associated with improved course and decreased frequency of exacerbations. Less is known about the genetic basis of SLE, which results from a multigene disease background and complex hereditary mechanisms. It is estimated that the disease may be conditioned by around 100 genes, that only in part are functionally determined. Only part of them is already functionally characterized. The role played by most of them is still unknown. Research currently being conducted is aimed at detecting genetic polymorphism in large and genetically diverse populations. It will allow evaluation of the role of a particular gene in protein biosynthesis, which is responsible for development of regulatory process disturbances, commonly observed in the course of SLE. The article presents current directions of research and the latest advances in epidemiology as well as environmental and genetic risk factors of SLE.
