Lupus eritematoso sistémico (LES): análisis de defunciones según sexo, grupo etario y región en Chile, durante el período 2016-2020.

Introduction: Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease, in which genetic and environmental factors are involved, that constitutes an important cause of morbidity and mortality in the population. For all of the above, and added to the fact that the epidemiology of SLE is poorly described in Chile, it is necessary to describe the deaths and mortality from this pathology in our country. General objective: To describe deaths from systemic lupus erythematosus according to sex, age group and region in Chile during the period 2016-2020. Materials and methods: Cross-sectional descriptive observational study. Deaths from SLE were studied as the basic cause of death (n = 388), according to sex, age group and region, during the period 2016-2020 in Chile. Data were obtained from the Department of Health Statistics and Information (DEIS). For the statistical analysis, the Microsoft Excel program was used. Due to the nature of the data, this study did not require a review by an ethics committee. Results: 388 deaths from SLE were studied and a mortality rate of 0,42 per 100.000 inhabitants was obtained throughout the period. Of all deads, 87,62% corresponded to women. The age group between 61 and 70 years was the one with the highest number of deaths (n = 106). The region with the highest mortality rate was Arica and Parinacota. Conclusions: SLE is a prevalent and complex pathology that determines an important morbidity and mortality in the general population. It was observed that deaths and the mortality rate from this pathology vary notably according to sex, age group and regions. [ABSTRACT FROM AUTHOR]
