Abstract

Background: Infective endocarditis (IE) is a rare condition in the paediatric setting. No data on the epidemiology and prognosis of IE in children are available from North African countries.

Aim: To investigate the epidemiological profile and prognosis of IE in children in Tunisia.

Methods: All patients aged≤18 years presenting with IE in three Tunisian tertiary care centres between January 1997 and September 2013 were included. Clinical features and 30-day and 6-month mortality rates were studied. Factors predictive of death at 6-month follow-up were determined.

Results: A total of 73 patients were included in the present study. The mean age was 12±4.8 years; 35 (50.7%) patients were male. Rheumatic heart disease (RHD) was the underlying heart disease in 17 (23.3%) cases and IE occurred in a structurally normal heart in 36 (49.3%) cases. Staphylococcus species were isolated in 17 (23.3%) cases. Regarding IE localization, the mitral valve was involved in 28 (38.4%) cases and the aortic valve in 14 (19.2%) cases. Recourse to surgery was reported in 37 (50.7%) cases. Thirty-day and 6-month mortality rates were 13.6% and 19.2%, respectively. Heart failure on admission or during the hospital course, acute renal failure and neurological complications were significantly associated with death at 6-month follow-up in the univariate analysis and after adjustment for age and sex.

Conclusions: In the Tunisian context, IE in children is still characterized by the high prevalence of RHD as an underlying heart disease. Short- and long-term mortality rates remain high. Heart failure, acute renal failure and neurological complications are significantly associated with death at 6-month follow-up.
