TauroSept-Induced Anaphylaxis: A Pediatric Case Report.

Abstract

Background: Children with intestinal failure who are receiving parenteral nutrition through a central venous catheter are at risk of developing catheter-related bloodstream infections. For many years, a prophylactic lock with taurolidine has been used to decrease the incidence of these infections and is considered safe in children. Case Presentation: A 1-month-old boy with jejunal atresia was receiving parenteral nutrition through a central venous catheter. Shortly after administration of taurolidine (TauroSept®), he developed circulatory insufficiency and angioedema. His serum tryptase increased, which was suggestive of anaphylaxis (baseline tryptase 6.3 µg/L; 2 h after start of the reaction: 21 µg/L; cutoff criterion for clinically relevant increase: 1.2 × baseline tryptase level + 2). Conclusions: To the best of our knowledge, this is the first case of anaphylaxis in response to TauroSept® in an infant worldwide. Clinicians should be aware of this possible but very rare side effect.
