[Mortality due to visceral leishmaniasis: clinical and laboratory characteristics].

Introduction: Visceral leishmaniasis is a systemic infectious disease of broad geographical distribution, characterized by high potential for lethality. With the purpose of contributing towards reducing mortality and helping healthcare professionals in clinical management of patients with this disease, this paper aimed to investigate the clinical and laboratory characteristics of cases with a fatal outcome in hospitals in Campo Grande, Mato Grosso do Sul, between 2003 and 2008.

Methods: Fifty-five medical files on patients who died due to visceral leishmaniasis were analyzed.

Results: Among the 55 patients studied, 37 were from the municipality of Campo Grande; 41 (74.5%) were males; and age over 40 years predominated. The patients presented with fever in 89.1% of the cases. The duration of the illness from the onset of symptoms to hospitalization was 78.2 days on average. Leukopenia was seen in 85.5% of the patients. Comorbidities were present in 39 (70.9%) patients; malnutrition and alcoholism were the most frequent of these. Confirmation of the diagnosis occurred on average 6.7 days after admission. Pentavalent antimoniate was the drug most used, and 87.5% of the patients presented some type of adverse reaction. Bacterial infections occurred in 36 patients and were one of the causes of death in 27 (49%).

Conclusions: The data showed that early identification of these clinical and laboratory characteristics, at the time when patients are first attended, is extremely important for reducing mortality through instituting efficient therapeutic and prophylactic measures.
