[Meningoradiculitis caused by a spirochete (Borrelia burgdorferi) after arthropod bite]
Abstract:
Eight cases of meningoradiculitis (Garin-Bujadoux-Bannwarth's syndrome) are presented; the first case followed an "unidentified insect" bite and erythema chronicum migrans, whereas the second and third cases were not preceded by any documented insect bite or erythema; they occurred during summer in 1984 and 1985 and were characterized by cranial or radicular neuritis, lymphocytic meningitis, positive serology by immunofluorescence against Borrelia Burgdorferi and a good response to Penicillin (20 000 000 U during 14 days I.V.). Five other cases were observed in the same area as the first and second cases (Walloon Brabant) during the preceding summers; in two, serological proof of Borrelia Burgdorferi infection was obtained retrospectively. Lyme disease and Garin-Bujadoux-Bannwarth syndrome are both tick-born spirochetosis, due to two slightly different subtypes of Borrelia Burgdorferi. Their early neurological manifestations differ mainly by focalised pain on the bitten region in Garin-Bujadoux-Bannwarth's syndromes. This could be due to direct aggression of the peripheral nerve in Garin-Bujadoux-Bannwarth syndrome.
Insights
Garin-Bujadoux-Bannwarth's syndrome, a neurological manifestation of Borrelia Burgdorferi infection, presents with cranial or radicular neuritis and lymphocytic meningitis. Early neurological symptoms may differ from Lyme disease due to potential direct nerve involvement.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Meningoradiculitis, also known as Garin-Bujadoux-Bannwarth's syndrome, is a neurological condition.
- Lyme disease and Garin-Bujadoux-Bannwarth's syndrome are both caused by Borrelia Burgdorferi, a spirochete transmitted by ticks.
- Understanding the nuances between these conditions is crucial for accurate diagnosis and treatment.
Observation:
- Eight cases of meningoradiculitis were observed, with some following insect bites and erythema chronicum migrans, while others had no documented preceding bite.
- Cases presented with cranial or radicular neuritis and lymphocytic meningitis.
- Serological testing confirmed Borrelia Burgdorferi infection in several patients.
Findings:
- Patients with meningoradiculitis responded well to intravenous Penicillin treatment.
- Early neurological manifestations in Garin-Bujadoux-Bannwarth's syndrome may differ from Lyme disease, potentially involving direct peripheral nerve aggression.
- Retrospective serological evidence confirmed Borrelia Burgdorferi infection in some cases.
Implications:
- This study highlights the clinical spectrum of Borrelia Burgdorferi infections.
- Differentiating Garin-Bujadoux-Bannwarth's syndrome from Lyme disease based on early neurological signs, particularly localized pain, is important.
- Prompt diagnosis and treatment with antibiotics like Penicillin are effective for meningoradiculitis.
