Abstract:
This case report describes a three-year-old boy with delayed development of language, who developed erythema migrans. Soon after peroral antibiotics was initiated, he also had loss of motoric function, and he developed ataxia. Neuroborreliosis was diagnosed, and antibiotic treatment was changed to intravenous. There was no gain of his motoric skills. A test was made for lysosomal storage disease, and neuronal ceroid lipofuscinosis type 2 was found. The patient started intraventricular enzyme substitution treatment as the first patient in Denmark. Treatment has shown to reduce the progression of functional decline.
Insights
A child with delayed development and erythema migrans was diagnosed with neuronal ceroid lipofuscinosis type 2. Early intraventricular enzyme therapy in Denmark slowed functional decline.
Area of Science:
- Pediatric Neurology
- Rare Genetic Diseases
- Infectious Diseases
Background:
- Delayed language development and erythema migrans in a pediatric patient.
- Initial misdiagnosis of neuroborreliosis and subsequent treatment challenges.
Observation:
- The patient presented with progressive motor dysfunction, including ataxia, following antibiotic treatment for suspected neuroborreliosis.
- Diagnostic workup revealed neuronal ceroid lipofuscinosis type 2, a rare lysosomal storage disease.
Findings:
- The patient received intraventricular enzyme substitution therapy, marking a first in Denmark.
- This novel treatment demonstrated a capacity to mitigate the advancement of functional deterioration.
Implications:
- Highlights the importance of considering rare genetic disorders in pediatric cases with complex neurological symptoms.
- Suggests potential efficacy of intraventricular enzyme therapy for neuronal ceroid lipofuscinosis type 2.
- Emphasizes the need for early diagnosis and intervention in lysosomal storage diseases.
