Clinical-epidemiological aspects and prognostic factors associated with death from visceral leishmaniasis between the years 2010 to 2019 in the Central-West region of Brazil.

In Brazil, the fatality rate for visceral leishmaniasis is high, and it is important to investigate its associated factors. The aim of this study was to analyze the clinical-epidemiological profile and prognostic factors associated with death from visceral leishmaniasis (VL) in the Central-West region of Brazil, between 2010 and 2019. A study of series of VL cases was carried out using data obtained from the Sistema de Informação de Agravos de Notificação (SINAN). Multivariate logistic regression was performed to identify variables associated with deaths. Male (64.96%); age group ≤5 years (28.51%); mixed race/color (59.20%); and level of education incomplete primary education (45.16%) were the most affected. The most frequent symptoms were fever (87.65%), weakness (77.56%), enlarged spleen (70.22%) and liver (67.33%), weight loss (67.22%) and pallor (63.41%). Co-infection with HIV was observed in 15.84% of patients. The parasitological diagnosis was positive in 74.17% and the Indirect Immunofluorescence (IIF) in 82.80%. The drug most used for treatment was pentavalent antimony (41.96%). Regarding the evolution of VL, cure was recorded for 82.90% of patients and death from VL in 8.30%. Factors associated with death from VL were: age group ≥20 and <60 (OR 2.95; 95% CI 1.98-4.38) and ≥60 (OR 5.84; 95% CI 3.63-9.38), edema (OR 2.27; 95% CI 1.64-3.13), pallor (OR 1.53; 95% CI 1.06-2.20), infectious condition (OR 1.56; 95% CI 1.12-2.15) and hemorrhagic phenomena (OR 2.87; 95% CI 2.02-4.08). New studies are needed in order to better manage VL control, monitoring, prevention and primary care strategies.
