Infantile botulism: a case report and review
1Department of Pediatrics, University of Louisville, Louisville, Kentucky.
Insights
Infantile botulism, a serious condition in infants under 6 months, presents with vague symptoms like poor feeding and weakness. Prompt diagnosis and treatment with botulism immunoglobulin are crucial for recovery.
Area of Science:
- Pediatric Medicine
- Infectious Diseases
- Toxicology
Background:
- Infantile botulism results from Clostridium botulinum spore ingestion, being the most common botulism form in the US.
- It predominantly affects infants under 6 months, often presenting with non-specific symptoms like hypotonia and poor feeding.
- This case highlights an infant presenting with decreased feeding and constipation, leading to an infantile botulism diagnosis.
Observation:
- A 4-month-old infant presented with a 6-day history of decreased feeding and 9 days of absent bowel movements.
- The infant exhibited progressive weakness, inability to hold his head up, decreased tone, and hypoactive bowel sounds.
- He required intubation and mechanical ventilation in the Pediatric Intensive Care Unit.
Findings:
- Diagnosis was confirmed by positive botulinum toxin detected in stool samples.
- Treatment involved the administration of botulism immunoglobulin.
- The infant made a full recovery.
Implications:
- Increased clinical suspicion and awareness of infantile botulism symptoms are vital for early diagnosis.
- Prompt recognition and management can lead to favorable outcomes in affected infants.
- This case underscores the importance of considering botulism in infants with descending weakness and feeding difficulties.
Background:
Infantile botulism is the result of ingestion of Clostridium botulinum spores, and is the most common form of infection with botulism in the United States. Ninety percent of cases occur in infants <6 months old. The infants typically present with vague symptoms such as hypotonia and poor feeding. This article reports an infant with confirmed infantile botulism that presented to the Emergency Department (ED) with complaints of decreased feeding and absence of bowel movements for >1 week.
Objectives:
Review a case of infantile botulism, its diagnosis, and treatment.
Case Report:
A 4-month-old healthy Caucasian male presented to the ED with a 6-day history of decreased feeding after referral from the pediatrician. He had not had a bowel movement for 9 days, and his parents were also concerned about increasing weakness, as he was no longer able to hold his head up on his own. In the ED, he was minimally interactive. His vital signs were within normal limits, and he had hypoactive bowel sounds and decreased tone throughout. He was admitted to the Children's Hospital and eventually transferred to the Pediatric Intensive Care Unit requiring intubation and mechanical ventilation. The botulism immunoglobulin was administered, and a diagnosis was confirmed with positive botulinum toxin in the stool samples. Full recovery was made by the infant.
Conclusion:
Awareness of the symptoms of botulism and a high degree of clinical suspicion is needed to make a prompt diagnosis.
