  • Title: Prognostic factors for death from visceral leishmaniasis in patients treated with liposomal amphotericin B in an endemic state in Brazil.
    Author: Dias Tourinho B, Figueiredo Amâncio F, Lencine Ferraz M, Carneiro M.
    Journal: Trans R Soc Trop Med Hyg; 2017 Apr 01; 111(4):163-171. PubMed ID: 28673017.
    Abstract:
    OBJECTIVE: To characterize the clinical and epidemiological profiles of patients with visceral leishmaniasis (VL) treated with liposomal amphotericin B (LAmB) and to identify prognostic factors for death from VL in 2008-2012 in the state of Minas Gerais, Brazil. METHODS: A historical cohort study was conducted using data obtained from treatment requests forms, Brazilian Notifiable Disease Information System and the Mortality Information System. Case-fatality rates of patients with VL treated with LAmB were compared with patients treated with other therapies. Logistic regression analysis was used to identify prognostic factors for death. RESULTS: The overall case-fatality rate of the 577 patients treated with LAmB was 19.4%. Prognostic factors for death from VL were age between 35 and 49 years (OR 2.7; 95% CI 1.3-5.4) and above 50 years (OR 2.6; 95% CI 1.3-4.9), jaundice (OR 2.2; 95% CI 1.2-3.7), kidney disease (OR 2.8; 95% CI 1.6-4.9), presence of other infections (OR 2.4; 95% CI 1.5-4.1), edema (OR 2.0; 95% CI 1.1-3.4), platelet count below 50.000/mm3 (OR 3.6; 95% CI 2.1-6.0), AST higher than 100 U/L (OR 2.2; 95% CI 1.3-3.8), and assistance in non-specialized institutions (OR 1.9; 95% CI 1.0-3.5). CONCLUSIONS: Case-fatality rates were higher than that observed among patients with VL treated with other therapies. Identification of prognostic factors of death from VL may allow early diagnosis of patients prone to such outcome and prompt an expeditious and appropriate management of VL to reduce fatality rates.
