Pneumococcal meningitis and endocarditis in an infant: possible improved survival with factor V Leiden mutation.

UNLABELLED: Streptococcus pneumoniae infections continue to remain associated with high morbidity and mortality. Although the incidence of invasive meningeal and/or lung disease are not uncommon, Streptococcus pneumoniae endocarditis is rare especially in healthy pediatric population. New studies have suggested a strong association between factor V leiden (FVL) mutation and favorable outcomes in critically ill children. A healthy 10 month old presented with sepsis and meningeal signs, was later confirmed to have Streptococcus pneumoniae meningitis and endocarditis. She was found to have factor V leiden mutation and made a complete recovery despite initial complications.

CONCLUSION

Presence of factor V leiden mutation in critically ill children with severe septicaemia possibly contributes to better outcomes. What is known: • Mortality and morbidity remain high with invasive pneumococcal disease. • Pneumococcal endocarditis is rare in healthy pediatric population and results in significant morbidity and mortality What is new: • New studies have suggested a strong association between factor V leiden (FVL) mutation and favorable outcomes in critically ill children. • The presence of factor V mutation in children with extensive invasive pneumococcal disease possibly contributes to a better outcome.
