We appreciate Dr Narita's letter in response to our article describing Mycoplasma pneumoniae–associated encephalitis in pediatric patients.1 Dr Narita describes 1 potential mechanism of encephalitis associated with M pneumoniae: induction of inflammatory cytokines on entry into the central nervous system.2 We agree that small amounts of organism that fall below the limit of detection by our polymerase chain reaction assays3 may be present in the central nervous system. Degradation of the organism in cerebrospinal fluid during transport could also lead to negative M pneumoniae polymerase chain reaction results. Given the large number of cases of M pneumoniae–associated encephalitis that we have identified and the serious nature of the disorder, we agree that increased emphasis and resources should be directed at investigating the role of steroids, antibiotics, and other treatment options.
