[Neurologic manifestations of Borrelia burgdorferi infections]
Abstract:
Lyme disease, first recognized in 1975, typically begins in summer with erythema chronicum migrans (ECM) followed some months later by neurological symptoms (meningoencephalitis, cranial neuropathy), associated with carditis and arthritis. Bannwarth's syndrome is characterized by an ECM followed by radicular pain and radicular sensory and motor disturbances, accompanied by aseptic meningitis. In both cases the cerebrospinal fluid typically shows marked lymphocytic pleocytosis accompanied by an oligoclonal reaction. Despite differences in the clinical symptoms, a borrelia isolated from ticks has been implicated as the etiologic agent of both diseases, and specific antibody titers usually reach a peak between the third and sixth week after onset of the disease. Investigations in 5 patients who developed neurologic symptoms after tick-borne borrelia infection revealed specific antibodies (IgM, IgG) against Borrelia burgdorferi in all sera, and all the patients recovered, one of them without treatment and the others under penicillin or tetracyclines. None developed major complications (carditis, arthritis).
Insights
Lyme disease and Bannwarth's syndrome share a tick-borne borrelia cause, often presenting with neurological symptoms. Early antibiotic treatment for Borrelia burgdorferi infection can lead to recovery without major complications.
Area of Science:
- Infectious Diseases
- Neurology
- Immunology
Background:
- Lyme disease, recognized in 1975, and Bannwarth's syndrome are tick-borne illnesses.
- Both conditions can manifest with neurological symptoms, including meningoencephalitis, cranial neuropathy, and aseptic meningitis.
Observation:
- Cerebrospinal fluid in affected individuals typically shows lymphocytic pleocytosis and an oligoclonal reaction.
- A common borrelia species isolated from ticks is implicated as the causative agent for both diseases.
- Specific antibody titers against Borrelia burgdorferi peak between 3-6 weeks post-onset.
Findings:
- Investigations on five patients with neurological symptoms post-tick-borne borrelia infection revealed specific IgM and IgG antibodies against Borrelia burgdorferi.
- All five patients recovered, with one showing spontaneous resolution and others responding to penicillin or tetracyclines.
- No major complications such as carditis or arthritis were observed in these patients.
Implications:
- This study reinforces the link between tick-borne borrelia and neurological manifestations.
- Early diagnosis and treatment of Borrelia burgdorferi infections appear crucial for preventing severe Lyme disease complications.
- Further research into the pathogenesis and treatment of neuroborreliosis is warranted.
