Insights
A 7-month-old boy developed acute transverse myelitis following diphtheria-tetanus-pertussis (DTP) immunization. This case highlights the potential association between DTP vaccination and transverse myelitis in infants.
Area of Science:
- Neurology
- Immunology
- Pediatrics
Background:
- Acute transverse myelitis is a rare neurological disorder.
- Vaccinations are crucial for preventing infectious diseases in infants.
Observation:
- A 7-month-old infant presented with acute transverse myelitis after receiving diphtheria-tetanus-pertussis (DTP) immunization.
- Clinical symptoms included urologic issues and partial motor function loss.
Findings:
- Magnetic resonance imaging (MRI) revealed diffuse spinal cord edema and enhancement.
- Steroid treatment improved urologic symptoms, but motor function recovery was incomplete.
- Follow-up MRI showed resolution of edema and cord abnormalities.
Implications:
- This case suggests a potential association between DTP vaccination and the development of acute transverse myelitis in infants.
- Further research is warranted to explore the immunologic mechanisms underlying this association.
- Understanding such adverse events is crucial for vaccine safety monitoring.
Study Design:
Case report of a 7-month-old boy, who developed acute transverse myelitis after diphtheria-tetanus-pertussis immunization.
Objectives:
To describe the clinical course of acute transverse myelitis in an infant and to review the literature regarding the association of acute transverse myelitis and vaccinations.
Setting:
Department of Pediatrics, University of Kentucky, Lexington, Kentucky, USA.
Methods:
Case report.
Results:
Magnetic resonance imaging (MRI) on admission demonstrated diffuse spinal cord edema with increased signal on T-2 weighted images and faint enhancement with gadolinium infusion. Urologic symptoms improved with steroids but motor function was never fully regained. Repeat MRI of the spinal cord several months later showed diminution of cord diameter with resolution of edema and signal abnormality.
Conclusion:
Based on the clinical course and MRI findings, the daignosis of acute transverse myelitis was made. The association of previously received DPT immunization and the genesis of transverse myelitis is explored.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
