AI Article Synopsis

  • The study compared infective endocarditis (IE) in children and adolescents to adults, using data from 31 hospitals in Spain between 2008 and 2020.
  • Among 5590 patients, only 49 were under 18, with 63.2% having congenital heart disease (CHD), which showed a preference for right-sided IE compared to adults.
  • Pediatric patients with CHD experienced a lower rate of heart failure, while those without CHD had clinical profiles similar to adults, including a focus on left-sided IE.

Article Abstract

Background: Our aim was to compare pediatric infective endocarditis (IE) with the clinical profile and outcomes of IE in adults.

Methods: Prospective multicenter registry in 31 Spanish hospitals including all patients with a diagnosis of IE from 2008 to 2020.

Results: A total of 5590 patients were included, 49 were <18 years (0.1%). Congenital heart disease (CHD) was present in 31 children and adolescents (63.2%). Right-sided location was more common in children/adolescents than in adults (46.9% vs. 6.3%, P < 0.001). Pediatric pulmonary IE was more frequent in patients with CHD (48.4%) than in those without (5.6%), P = 0.004. Staphylococcus aureus etiology tended to be more common in pediatric patients (32.7%) than in adults (22.3%), P = 0.082. Heart failure was less common in pediatric patients than in adults, due to the lower rate of heart failure in children/adolescents with CHD (9.6%) with respect to those without CHD (44.4%), P = 0.005. Inhospital mortality was high in both children, and adolescents and adults (16.3% vs. 25.9%; P = 0.126).

Conclusions: Most IE cases in children and adolescents are seen in patients with CHD that have a more common right-sided location and a lower prevalence of heart failure than patients without CHD. IE in children and adolescents without CHD has a more similar profile to IE in adults.

Impact: Infective endocarditis (IE) in children and adolescents is often seen in patients with congenital heart disease (CHD). Right-sided location is the most common in patients with CHD and heart failure is less common as a complication compared with patients without CHD. Infective endocarditis (IE) in children/adolescents without CHD has a more similar profile to IE in adults. In children/adolescents without CHD, locations were similar to adults, including a predominance of left-sided IE. Acute heart failure was the most frequent complication, seen mainly in adults, and in children/adolescents without CHD.

Phage therapy is experiencing renewed interest, particularly for antibiotic-resistant infections, and may also be useful for difficult-to-treat cases where surgery to remove foreign infected material is deemed too risky. We report a case of recurrent endocarditis with Bentall infection treated successfully with a combination of antibiotics and phages.

Previous studies evaluated the prognostic role of hematological parameters in predicting outcome in patients with infective endocarditis (IE). However, only a few studies evaluated the role of hematological parameters in patients undergoing surgery for IE. The aim of this study was to review our 20-year experience with the treatment of native (NVE) and prosthetic (PVE) valve endocarditis and to evaluate the role of neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-platelet ratio (NPR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), neutrophil-to monocyte ratio (NMR), and systemic inflammatory index (SII) on early and long-term outcomes of patients undergoing surgery for NVE and PVE.
