Pericarditis during infliximab therapy in paediatric ulcerative colitis.

WHAT IS KNOWN AND STUDY OBJECTIVE

Infliximab is a widely used drug for treating inflammatory bowel disease (IBD). This drug is known to rarely cause pericarditis in adult populations.

CASE SUMMARY

This report details the case of a 14-year-old boy with ulcerative colitis who developed pericarditis after a second infliximab infusion. After discontinuation of therapy, the patient's symptoms were resolved.

WHAT IS NEW AND CONCLUSION

To our knowledge, this is the first reported paediatric case of pericarditis as a possible complication of infliximab therapy in IBD. Among infliximab-related delayed adverse reactions, cardiac complications should be monitored in the paediatric population.
