Abstract:
Although infectious myelopathies are rare, appropriate aetiological diagnosis is of crucial importance to improve outcome. Lyme disease causes a myelomeningoradiculitis during the second stages and a progressive encephalomyelitis during the third stage. Serum and cerebrospinal fluid antibody tests are the basis of diagnosis. Myelopathy usually responds to treatment with ceftriaxone or doxycycline. Vacuole myelopathy occurs in patients with human immunodeficiency virus infection. It is characterised by a progressive spastic and ataxic paraparesis. About half of patients have symptoms of dementia. No specific treatment is available. Human T-cell lymphotropic virus type I is endemic in tropical areas and particularly in French West Indies. It causes a chronic spastic paraparesis with sexual and bladder dysfunction. Diagnosis depends on the positive antibody response in both serum and cerebrospinal fluid, and on the exclusion of other causes of spinal cord disease. There is no specific treatment.
Insights
Diagnosing rare infectious myelopathies like Lyme disease, vacuole myelopathy (HIV), and HTLV-I myelopathy is vital for patient outcomes. Early diagnosis guides treatment, though some conditions lack specific therapies.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Context:
- Infectious myelopathies, though rare, necessitate accurate etiological diagnosis for improved patient outcomes.
- Lyme disease, HIV, and Human T-cell lymphotropic virus type I (HTLV-I) are key causes of myelopathy with distinct clinical presentations.
- Diagnostic approaches rely on serological and cerebrospinal fluid antibody testing, alongside exclusion of other spinal cord diseases.
Purpose:
- To highlight the importance of diagnosing infectious myelopathies.
- To differentiate between Lyme disease, vacuole myelopathy, and HTLV-I myelopathy.
- To outline diagnostic strategies and treatment considerations for these rare neurological conditions.
Summary:
- Lyme disease causes myelomeningoradiculitis or encephalomyelitis, diagnosed via antibody tests, and often treated with ceftriaxone or doxycycline.
- Vacuole myelopathy in HIV patients presents as progressive paraparesis and dementia, with no specific treatment available.
- HTLV-I myelopathy, endemic in tropical regions, causes chronic spastic paraparesis and dysfunction, diagnosed by antibody response and exclusion, with no specific treatment.
Impact:
- Accurate diagnosis of infectious myelopathies is crucial for timely and appropriate management, potentially improving neurological outcomes.
- Understanding the specific etiology guides therapeutic decisions, even in cases where definitive treatments are limited.
- This review emphasizes the need for vigilance in identifying these rare but significant causes of spinal cord dysfunction.
