Invasive meningococcal disease-induced myocarditis in critically ill adult patients: initial presentation and long-term outcome
Myocarditis lesions have been found in up to three-quarters of children and young adults dying from invasive meningococcal disease (IMD) with histopathological examinations identifying Neisseria meningitidis in the injured myocardium [1, 2]. These features strongly differ from the usual septic cardiomyopathy, in which neither myocardial necrosis nor the presence of bacteria in the heart are observed . Because the clinical data on IMD-induced myocarditis remain scarce, we aimed to describe the initial presentation and long-term outcome of IMD-induced myocarditis in critically ill adult patients.
We conducted a 12-year observational, retrospective, multicentric study in four French academic intensive care units (ICUs). The study received approval from our institutional review board. IMD was diagnosed in adults (>16 years old) when Neisseria meningitidiswas isolated from usually sterile fluids or tissues. Myocarditis diagnosis was retained, according to the position statement of the...
