Compartmentalization of interleukin-6 response in a patient with septic meningococcal peritonitis

We report the first case of Neisseria meningitidis-induced septic peritonitis diagnosed by PCR assay of peritoneal fluid. Concentrations of interleukin-6 were notably higher in the peritoneal fluid than in the blood. PCR diagnosis of septic meningococcal peritonitis and the pathogenesis of the disease are discussed.
