Insights
Salmonella urbana infection can cause severe encephalopathy in children, leading to neurological deficits. Prompt recognition and management are crucial for this rare but potentially fatal complication.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
Background:
- Salmonella infections, particularly non-typhoidal strains, are common in children.
- Encephalopathy is a rare but serious neurological complication associated with Salmonella infections.
Observation:
- A 5-year-old boy presented with convulsions and coma, indicative of acute encephalopathy.
- Cerebrospinal fluid (CSF) analysis revealed elevated levels of proinflammatory cytokines, including interleukin-6 (IL-6) and IL-8, at the onset of illness.
Findings:
- The child developed severe neurological deficits, including mental impairment and spastic tetraplegia, following the infection.
- Elevated CSF proinflammatory cytokines correlated with central nervous system (CNS) disease activity.
Implications:
- This case highlights the potential for Salmonella urbana infection to cause severe encephalopathy in pediatric patients.
- Clinicians should consider Salmonella infection in the differential diagnosis of pediatric encephalopathy, even in the absence of typical gastrointestinal symptoms.
- The findings suggest a link between high CSF cytokine levels and the severity of CNS involvement in Salmonella-associated encephalopathy.
Abstract:
We present a case report of encephalopathy associated with Salmonella urbana infection in a child. A 5-year-old boy was admitted to our clinic with convulsions and coma. Cerebrospinal fluid (CSF) interleukin-6 (IL-6) and IL-8 were elevated at onset and were decreased within normal limit on the fifth day. Residual neurological deficits included severe mental deficits and spastic tetraplegia. High levels of CSF proinflammatory cytokines might be related to central nervous system (CNS) disease activity. Although encephalopathy is a rare complication of non-typhi Salmonella infection, it should be borne in mind as an occasionally serious and potentially lethal disease.
