Failure of multiplex meningitis/encephalitis (ME) NAT during cryptococcal meningitis in solid organ recipients.

Cryptococcal meningitis is a severe cause of central nervous system infections among immunocompromised solid organ transplant (SOT) patients. While new diagnostic methods as multiplex meningitis/encephalitis (ME) NAT (nucleic acid test) are increasingly used as a first-line tool in hospital practice, data in HIV-negative patients including SOT remain scarce. We report here false-negative results of multiplex NAT among SOT patients with proven cryptococcal meningitis.
