Risk factors for mortality of children with zoonotic visceral leishmaniasis in Central Tunisia.


ABSTRACT: Zoonotic visceral leishmaniasis (ZVL) caused by Leishmania infantum is endemic with an epidemiological profile of a paediatric disease in Tunisia. In the context of a high fatality rate, identifying risk factors for in-hospital mortality in children treated for ZVL is of major epidemiological importance.A retrospective (case-control) study included 230 immuno-competent children diagnosed and confirmed with primary ZVL in the paediatric department of the University Hospital of Kairouan between 2004 and 2014. Forty-seven per cent (47%) were children under 18 months of age, and with a male ? female ratio of 1.01:1.The overall case-fatality was 6% (n = 14). The risk factors for in-hospital death identified by a multivariate analysis were: bleeding at admission (OR = 25.5, 95% CI: 2.26-287.4; p = 0.009), white cell count less than 4000/mm3 (OR = 5.66, 95% CI: 1.16-27.6; p = 0.032), cytolysis (OR = 28.13, 95% CI: 4.55-173.6; p < 0.001), and delay between onset of symptoms and admission ? 15 days (OR = 11, 95% CI: 1.68-72; p = 0.012).The results strongly suggest that paediatric patients admitted 15 days after onset of symptoms, with bleeding, white cell counts below 4,000/mm3, and cytolysis at admission should be considered severe cases and subsequently, they are at high risk of mortality. A better understanding of factors associated with death of children from ZVL may contribute to decrease mortality.
