Insights
Children using home acid-suppressive therapy with histamine-2 receptor antagonists (H2RAs) face a nearly 4.5 times higher risk of Clostridium difficile infection (CDI). Further research into H2RA use in pediatric patients is warranted.
Area of Science:
- Pediatric Infectious Diseases
- Gastroenterology
- Pharmacology
Background:
- Acid-suppressing agents are linked to increased Clostridium difficile infection (CDI) risk in adults.
- The association between acid-suppressing therapy and CDI in children remains less understood.
Purpose of the Study:
- To evaluate the association between acid-suppressing therapy and the development of CDI in a pediatric population.
- To identify specific acid-suppressing agents that may increase CDI risk in children.
Main Methods:
- A retrospective case-control study design was employed.
- Children aged 1-17 years with positive C. difficile PCR results were matched with controls having negative PCR results.
- Data on acid-suppressive therapy use prior to PCR testing were collected and analyzed.
Main Results:
- No significant difference in overall acid-suppressive therapy use was found between CDI-positive and CDI-negative pediatric patients.
- However, histamine-2 receptor antagonist (H2RA) use was significantly higher in CDI-positive children (32.8%) compared to CDI-negative children (14.9%).
- Home H2RA therapy was identified as an independent predictor of CDI in children (odds ratio = 4.6).
Conclusions:
- Pediatric patients receiving home H2RA therapy exhibit a substantially increased risk of developing CDI.
- These findings highlight the need for careful consideration and monitoring of H2RA use in children.
- Further investigation into the mechanisms and implications of H2RA-associated CDI in pediatric populations is recommended.
Background:
Acid-suppressing agents have been associated with increased Clostridium difficile infection (CDI) in adults. The objective of this study was to evaluate the association of acid-suppressing therapy with the development of CDI in the pediatric population.
Methods:
This was a retrospective case-control study. Children aged 1 through 17 years with a positive C difficile polymerase chain reaction (PCR) result obtained between June 1, 2008, and June 1, 2012, were randomly matched to a control population selected from patients with negative PCR.
Results:
A total of 458 children were included. No difference was observed in acid-suppressive therapy prior to PCR in CDI-positive versus -negative patients (n = 131 [57.2%] vs n = 121 [52.8%], P = .348). Among patients receiving acid-suppressing therapy prior to obtaining a PCR, no difference was observed in proton pump inhibitor use (45% vs 46.3%, P = .843), but histamine-2 receptor antagonist (H2RA) use was greater in the CDI-positive patients (32.8% vs 14.9%, P = .001). Logistic regression analysis demonstrated that H2RA therapy at home (odds ratio = 4.6; 95% confidence interval = 1.5-14.5) was an independent CDI predictor.
Conclusion:
In this pediatric population, CDI risk in children receiving home acid-suppressive therapy with H2RAs is nearly 4.5 times greater than that of children not receiving H2RA therapy. These results suggest the need for continued monitoring and study of H2RA therapy in children.
