Abstract:
Mycoplasma pneumoniae infection is common in children. Extrapulmonary symptoms usually reveal as neurological symptoms, mainly as encephalitis with significant morbidity and mortality. Various other neurological presentations have also been reported. We describe a cohort of nine children with neurological manifestations due to M. pneumoniae infection, including five cases of encephalitis, one of polyradiculoneuritis, one of ophthalmoplegia, one of optic neuritis, and one of myositis. Progression was variable from ad integrum recovery to severe brain damage. Diagnosis is usually confirmed by PCR and/or serological follow-up, but the latter is still insufficiently used in practice to systematically affirm the diagnosis. Therapeutic management is not clearly defined and long-term progression can be uncertain despite early antibiotic and/or anti-inflammatory treatments.
Insights
Mycoplasma pneumoniae infections in children can cause serious neurological issues like encephalitis. Early diagnosis and treatment are crucial, though outcomes vary widely.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neuroimmunology
Context:
- Mycoplasma pneumoniae is a common childhood pathogen.
- Extrapulmonary manifestations, particularly neurological symptoms, are significant causes of morbidity and mortality.
- Neurological presentations range from encephalitis to peripheral neuropathies.
Purpose:
- To describe a cohort of children with neurological manifestations secondary to Mycoplasma pneumoniae infection.
- To highlight the diverse range of neurological presentations.
- To discuss diagnostic and therapeutic challenges.
Summary:
- A cohort of nine children with Mycoplasma pneumoniae-associated neurological disorders was analyzed.
- Presentations included encephalitis, polyradiculoneuritis, ophthalmoplegia, optic neuritis, and myositis.
- Diagnostic confirmation often relies on PCR and serology, with serological follow-up underutilized.
- Treatment strategies are not standardized, and long-term outcomes are variable, ranging from full recovery to severe neurological deficits.
Impact:
- This study underscores the importance of considering Mycoplasma pneumoniae in pediatric neurological cases.
- It emphasizes the need for improved diagnostic approaches and standardized treatment protocols.
- Understanding the spectrum of neurological involvement can guide clinical management and improve patient outcomes.
