PRELHAZ, Carolina et al. Food-protein induced proctocolitis in an exclusive breastfed infant. Rev Port Imunoalergologia [online]. 2019, vol.27, n.1, pp.55-59. ISSN 0871-9721.  https://doi.org/10.32932/rpia.2019.03.006.

Introduction: Food -protein induced proctocolitis is a non -IgE mediated hypersensitivity reaction, most often triggered by the ingestion of cow’s or soy milk but it has also been recognized in exclusive breastfed infants. It may occur in the first weeks of life and its diagnosis is challenging given the lack of specificity of clinical manifestations, often leading to invasive and unnecessary medical interventions. Clinical report: The authors present a one-month old infant, exclusively breastfed, admitted for bloody stools, irritability and declining oral intake, whose clinical investigation was consecutively negative and whose clinical manifestations reversed after excluding breast milk eviction and introducing of extensively hydrolyzed milk. Conclusions: The exclusion of the triggering food protein usually leads to complete clinical response and no late sequelae. It may be necessary to stop breastfeeding in infants in whom no other cause for hypersensitivity has been identified.
