Mycoplasma-induced minimally conscious state

Area of Science:

• Neurology
• Infectious Diseases
• Immunology

Background:

• Mycoplasma pneumoniae commonly causes respiratory infections, often mild or self-limiting.
• Extrapulmonary manifestations, particularly central nervous system (CNS) disease, are more frequent in children than adults.
• Severe CNS involvement in adults is rare but can be devastating.

Purpose of the Study:

• To report a rare case of fulminant Mycoplasma pneumoniae-induced encephalomyelitis in an adult.
• To emphasize that severe M. pneumoniae-related neurological disease can occur in adults.
• To discuss treatment challenges and the need for effective therapies.

Main Methods:

• Case report of a previously healthy immunocompetent adult with severe M. pneumoniae-induced encephalomyelitis.
• Detailed description of clinical presentation, neurological progression, and treatment interventions.
• Review of existing literature on M. pneumoniae-associated CNS disease.

Main Results:

• The patient developed progressive encephalomyelitis with ascending transverse myelitis, leading to paraplegia and locked-in syndrome.
• Despite early and aggressive antimicrobial, anti-inflammatory, and immunosuppressive therapy, neurological recovery was limited.
• The patient remained in a persistent minimally conscious state at 230 days of follow-up.

Conclusions:

• Severe M. pneumoniae-induced encephalomyelitis is a critical consideration in adults, not just children.
• Fulminant neurological disease and poor outcomes are possible in adults.
• The case underscores the need for optimal antimicrobial agents with CNS penetration and highlights challenges in early treatment decisions for potentially self-limiting M. pneumoniae infections.
