Epidemiological Profile of Patients with Infective Endocarditis at three Tertiary Centers in Brazil from 2003 to 2017

Abstract Background Infective endocarditis (IE) is a disease with high morbimortality and an increasing incidence. With improved diagnosis and treatment, a number of epidemiological changes have been reported over time. Objectives We sought to describe the epidemiological profile, mortality predictors, and analysis of a possible microbiological transition in patients admitted to three tertiary centers in Brazil. Methods In this cross-sectional retrospective study, data from 211 patients with definite or probable IE were analyzed according to the modified Duke criteria between 2003 and 2017. The association between categorical variables was assessed using the chi-square or Fisher's exact test, and binary logistic models were built to investigate mortality. We considered p <0.05 statistically significant. Results The median age of the sample was 48 (33-59) years old, 70.6% were men, and the most prevalent pathogen was Staphylococcus spp. (19%). Mortality was 22.3%, with increasing age being the leading risk factor for death (p = 0.028). Regarding the location of the disease, native valves were the most affected site, with the aortic valve being more affected in men than women (p = 0.017). The mean number of cases of Staphylococcus spp. (τ = 0.293, p = 0.148) and Streptococcus spp. (τ = -0.078, p = 0.727) has remained stable over the years. Conclusion No trend towards reduced or increased mortality was evident between 2003 and 2017. Although Staphylococcus spp. were the most prevalent pathogen, the expected epidemiological transition could not be observed.
