Background: The aim of this study was to investigate factors associated with poor outcomes among elderly hospitalized patients with leptospirosis. Methods: This is a retrospective cohort study with leptospirosis patients admitted to three tertiary hospitals in Fortaleza, Brazil, from January 1985 to July 2017. Patients were divided into two groups: elderly (age ≥60 years) and young (age <60 years). A comparison of demographical, clinical and laboratory data, treatment and outcomes was executed in order to investigate differences between groups. Results: A total of 507 hospitalized patients were included, with mean age 38 ± 15 years. Elderly group presented lower incidence of myalgia, vomiting, and dyspnea, as well as, higher medium systolic blood pressure. Elderly also manifested higher frequency of AKI (85.9 vs. 74.7%, p = 0.05), hemodialysis requirement (54.7 vs. 37.0%, p = 0.007) and death (32.8 vs. 12.2%, p < 0.001). In multivariate analysis, age ≥60 years was a predictor of hemodialysis requirement (p = 0.008, OR = 2.049, 95% CI = 1.207–3.477) and death (p < 0.001, OR = 3.520, 95% CI = 1.940–6.386). Conclusion: Leptospirosis in the elderly is associated with less hemodynamic impairment and higher frequency of AKI. Advanced age was also a predictor of poor outcomes, such as hemodialysis requirement and death, mostly due to kidney involvement. [ABSTRACT FROM AUTHOR] |
