Insights
Rectal bleeding in infants is often misdiagnosed as food protein-induced allergic proctocolitis (FPIAP). Consider benign non-allergic proctocolitis first, delaying dietary elimination for at least two months.
Area of Science:
- Pediatrics
- Gastroenterology
- Allergy Immunology
Background:
- Rectal bleeding in infancy is frequently attributed to food protein-induced allergic proctocolitis (FPIAP).
- FPIAP symptoms typically manifest in early infancy and often resolve by 12 months of age.
- Common FPIAP signs include mucus-mixed bloody stools and potential changes in stool consistency, with infants usually appearing generally healthy.
Observation:
- A case highlights the importance of considering benign non-allergic proctocolitis.
- This benign condition is often overlooked in the differential diagnosis of infant rectal bleeding.
- It should be suspected in well-appearing infants without warning signs.
Findings:
- Benign non-allergic proctocolitis is a potential cause of infant rectal bleeding.
- Misdiagnosis can lead to unnecessary dietary restrictions.
- Prompt diagnosis of benign non-allergic proctocolitis avoids unnecessary food elimination.
Implications:
- Suggests a diagnostic approach prioritizing benign non-allergic proctocolitis in specific infant cases.
- Recommends a waiting period of at least two months before initiating dietary changes for suspected FPIAP.
- Emphasizes accurate diagnosis to prevent iatrogenic nutritional deficiencies and parental anxiety.
Abstract:
The presence of rectal bleeding in the first months of life is very often diagnosed as food protein-induced allergic proctocolitis (FPIAP). The symptoms typically start in infancy, and most cases resolve by age 12 months. Infants with FPIAP usually present bloody stools mixed with mucus, with or without reduced stool consistency. Most affected infants are generally healthy-appearing. We used the story of an infant with rectal bleeding as a reminder that there is also the possibility of a form of benign non-allergic proctocolitis that is not usually included in the differential diagnosis. In the absence of warning signs and in case of infant well-being, it should be the first clinical entity to suspect. Therefore, we suggest we should wait at least 2 months before starting to eliminate cow milk or other foods from the diet.

Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
