[Ketotifen poisoning in infancy?]
1Institut für Rechtsmedizin, Universität Freiburg.
Abstract:
A male baby aged 3 1/2 months died about 3 hours after application of ketotifen due to chyme aspiration. Apart from a mycotic napkin rash the post-mortem examination did not show any other pre-existing pathological findings. When analysing blood samples toxicologically we observed a remarkably high concentration of ketotifen whereas the urine level was comparatively low. The morphological and toxicological findings are presented and discussed in differential diagnosis with reference to sudden infant death syndrome.
Insights
A 3-month-old infant died from chyme aspiration after ketotifen use. High blood ketotifen levels suggest a potential link, warranting further investigation into infant safety.
Area of Science:
- Pediatric Toxicology
- Forensic Pathology
Background:
- Sudden Infant Death Syndrome (SIDS) is a leading cause of post-neonatal mortality.
- Ketotifen is an antihistamine medication sometimes used in infants.
Observation:
- A 3.5-month-old male infant experienced fatal chyme aspiration 3 hours post-ketotifen administration.
- Post-mortem examination revealed no significant pre-existing pathological conditions, aside from a mycotic napkin rash.
Findings:
- Toxicological analysis of blood samples showed remarkably high ketotifen concentrations.
- Urine ketotifen levels were comparatively low, suggesting altered metabolism or distribution.
Implications:
- This case highlights a potential association between high ketotifen blood levels and adverse outcomes in infants.
- Further research is needed to understand ketotifen pharmacokinetics and safety profiles in this age group.
- Consideration of ketotifen toxicity in differential diagnosis for unexplained infant deaths is warranted.
