Insights
Ventriculoperitoneal shunt (VPS) infections in children are common, with coagulase-negative staphylococci being the most frequent pathogen. High cerebrospinal fluid (CSF) protein levels before shunt re-insertion may increase the risk of re-infection.
Area of Science:
- Pediatric Neurosurgery
- Infectious Diseases
- Medical Device Complications
Background:
- Ventriculoperitoneal shunts (VPS) are standard treatment for hydrocephalus.
- VPS infections are serious complications, leading to high mortality and morbidity.
- Identifying causative agents and risk factors for re-infection is crucial for pediatric patients.
Purpose of the Study:
- Investigate the causative agents of VPS infections in children.
- Analyze the management strategies for VPS infections.
- Identify risk factors associated with VPS re-infection in pediatric cases.
Main Methods:
- Retrospective, multicentre study conducted in Turkey.
- Involved pediatric and neurosurgery departments across four tertiary medical centers.
- Data collected from January 2011 to September 2014.
Main Results:
- 290 patients with VPS infections were identified.
- Coagulase-negative staphylococci were the most common pathogen (42.5%), followed by Pseudomonas aeruginosa.
- Elevated CSF protein levels (>100 mg/dL) prior to VPS insertion were linked to a higher risk of re-infection (OR, 1.65; p=.01).
Conclusions:
- High pre-insertion CSF protein levels (>100 mg/dL) may indicate an increased risk for VPS re-infection.
- Prompt identification and management of causative agents are essential.
- Further research into preventative strategies for VPS infections is warranted.
Purpose:
Ventriculoperitoneal shunt (VPS) is the most common treatment modality for hydrocephalus. However, VPS infection is a common and serious complication with high rates of mortality and morbidity. The objective of this study was to investigate causative agents and the management of VPS infections and to identify risk factors for re-infection in children.
Materials And Methods:
Retrospective, multicentre study on patients with VPS infection at paediatric and neurosurgery departments in four tertiary medical centres in Turkey between January 2011 and September 2014.
Results:
A total of 290 patients with VPS infections were identified during the study period. The aetiology of hydrocephalus was congenital malformations in 190 patients (65.5%). The most common symptom of shunt infection was fever in 108 (37.2%) cases. At least one pathogen was identified in 148 VPS infections (51%). The most commonly isolated pathogen was coagulase-negative staphylococci, which grew in 63 cases (42.5%), followed by Pseudomonas aeruginosa in 22 cases (14.9%), Klebsiella pneumoniae in 15 cases (10.1%), and Staphylococcus aureus in 15 cases (10.1). The median duration of VPS infection was 2 months (range, 15 days to 60 months) after insertion of the shunt, with half (49.8%) occurring during the first month. VPS infection was treated by antibiotics and shunt removal in 211 cases (76.4%) and antibiotics alone without shunt removal in 65 patients (23.5%). Among the risk factors, CSF protein level greater than 100 mg/dL prior to VPS insertion was associated with a potential risk of re-infection (OR, 1.65; p =.01).
Conclusion:
High protein levels (>100 mg/dL) before the re-insertion of a VPS may be a risk factor for VPS re-infection.
