Lyme meningoencephalitis: report of a severe, penicillin-resistant case
Abstract:
Although Lyme disease frequently attacks the central nervous system, this involvement is rarely severe, and high-dose intravenous penicillin usually is adequate treatment. The patient we describe developed severe Lyme meningoencephalitis despite receiving a full course of penicillin, and his condition continued to deteriorate after reinstitution of this treatment. Intravenous chloramphenicol was used successfully and resulted in a substantial improvement.
Insights
Severe Lyme meningoencephalitis can occur even with penicillin treatment. Intravenous chloramphenicol proved effective in a patient whose condition worsened despite standard care for this central nervous system Lyme disease complication.
Area of Science:
- Neuroscience
- Infectious Diseases
- Medical Research
Background:
- Lyme disease, caused by Borrelia burgdorferi, commonly affects the central nervous system.
- Neurological involvement in Lyme disease is typically mild and responsive to standard antibiotic therapy, such as intravenous penicillin.
Observation:
- A patient presented with severe Lyme meningoencephalitis, a rare and serious manifestation of the disease.
- The patient's neurological symptoms continued to worsen despite completing a full course of high-dose intravenous penicillin.
- Reinstituting penicillin treatment did not lead to clinical improvement, indicating treatment failure.
Findings:
- The case highlights a rare instance of severe central nervous system Lyme disease refractory to standard penicillin therapy.
- Successful treatment was achieved using intravenous chloramphenicol, leading to significant clinical improvement in the patient.
Implications:
- This case suggests that chloramphenicol may be a viable alternative treatment for severe or refractory Lyme meningoencephalitis.
- Further research is warranted to explore the efficacy and safety of chloramphenicol in treating severe Lyme neuroborreliosis.
- Clinicians should consider alternative antibiotic regimens for patients with severe Lyme meningoencephalitis who do not respond to penicillin.
