Insights
A rare bacterial infection, Clostridium ventriculi, was identified in a child with phenylketonuria (PKU) during a feeding tube removal. This highlights infection risks in disabled children.
Area of Science:
- Microbiology
- Pediatrics
- Gastroenterology
Background:
- Disabled individuals face increased risks for various infections.
- Phenylketonuria (PKU) is a rare genetic disorder requiring specialized dietary management.
- Percutaneous endoscopic gastrostomy (PEG) tubes are used for nutritional support in certain pediatric cases.
Observation:
- A 13-year-old female with PKU, previously treated with a PEG tube, presented for fistula closure.
- Histological examination of the fistula tract revealed inflammation and gram-positive bacteria.
- The bacteria exhibited a characteristic tetrad packet arrangement, identified as Clostridium ventriculi (formerly Sarcina ventriculi).
Findings:
- This case represents the 11th reported instance of Clostridium ventriculi infection in the literature.
- This is the first documented case of Clostridium ventriculi infection in a patient with phenylketonuria.
- The infection was associated with a gastrocutaneous fistula tract after PEG tube removal.
Implications:
- Clostridium ventriculi infections are rare, particularly in pediatric populations.
- Physically and mentally disabled children are more susceptible to infections due to unique care needs.
- Early identification and understanding of rare infections are crucial for managing vulnerable patient groups.
Abstract:
Disabled individuals may be at risk for common and rare infections. We report on a 13-year-old female who had a diagnosis of phenylketonuria (PKU). The child received a percutaneous endoscopic gastrostomy (PEG) feeding tube at five years of age for the supplementation of her specialized formula. After eight years, she no longer required the gastrostomy tube for formula supplementation, and she presented for the closure of the gastrocutaneous fistula tract. The histological examination revealed acute and chronic inflammation and colonization by gram-positive bacteria with a characteristic tetrad packet arrangement known as Clostridium ventriculi (formerly Sarcina ventriculi). A review of the literature evidenced the rarity of this infection in children. This patient is the 11th case of such infection in literature, and the first patient affected with PKU. Physically and mentally disabled children are particularly vulnerable to infection because of their different feeding abilities, toilet needs, and sanitary arrangements.
