Summary
This study details a rare, rapidly progressing case of tabes dorsalis in a patient with selective IgA deficiency (sIgAD). The findings suggest sIgAD may influence the atypical clinical course of this neurosyphilis manifestation.
Area of Science:
- Neurology
- Immunology
- Infectious Diseases
Background:
- Tabes dorsalis, a manifestation of neurosyphilis, typically progresses slowly.
- Selective IgA deficiency (sIgAD) is an immunodeficiency affecting antibody production.
Observation:
- A 28-year-old male presented with rapid-onset lightning back pain, nausea, and bladder/bowel dysfunction.
- Diagnostic tests revealed high Treponema pallidum antibodies in serum and cerebrospinal fluid (CSF), alongside critically low serum IgA levels (<5 mg/dl).
- Cytokine analysis showed a Th1-dominant profile, characteristic of neurosyphilis.
Findings:
- The patient was diagnosed with rapidly progressive tabes dorsalis associated with selective IgA deficiency.
- Treatment with Ceftriaxone led to the resolution of CSF pleocytosis.
- A correlation between sIgAD and the accelerated clinical presentation of tabes dorsalis is hypothesized.
Implications:
- This case highlights a potential link between selective IgA deficiency and atypical, rapid neurosyphilis progression.
- Understanding this association may refine diagnostic and treatment strategies for neurosyphilis in immunocompromised individuals.
- Further research is warranted to elucidate the immunological mechanisms underlying this rare presentation.
