A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- CMPA is a multi-system condition - the multi-system picture is the key feature distinguishing it from simpler diagnoses like infantile colic or reflux.
- Gastrointestinal - vomiting, colicky abdominal pain, loose/blood-streaked stools
- Cutaneous - erythematous rash, eczematous skin changes
- Faltering growth - reflects poor intake and gut inflammation; always prompts consideration of CMPA
- Onset typically before 6 months, correlating with introduction of formula or complementary foods; onset after 12 months is unusual
The exam vignette: infant under 6 months with multi-system features (GI + skin rash + faltering growth) in the context of formula or mixed feeding. Multi-system involvement rules out single diagnoses - colic has no rash or growth failure; reflux has no rash or growth failure; CMPA ties the picture together.
