Discrepancy between Mexican paediatricians and ESPGHAN experts regarding cow's milk allergy.

Objectives: Cow's milk allergy (CMA) is a common food allergy in infants. Guidelines and recommendations for the diagnosis and management of CMA are based on scientific review of the available evidence. However, real-world situations may oblige clinicians to adapt a different attitude.

Methods: This paper evaluated the opinion of 42 Mexican paediatricians on the 73 statements presented in the recent position paper of the European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). Voting on the statements and their interpretation were identical for both groups (online and anonymous). Both groups were unaware of the other's outcome at the moment of the voting.

Results: While the ESPGHAN group accepted all 73 statements, the Mexican group rejected 19 statements. Two rejections were due to the mean and median being below the predefined and agreed-upon cut-off, and 17 were due to over 75% of participants disagreeing with the statements. The greatest discrepancy was observed regarding the role of vitamin D in preventing CMA.

Conclusion: While opinions on the prevalence, diagnosis and management of CMA were comparable between European paediatric gastroenterologists and Mexican general paediatricians for the majority of statements, significant differences were observed. It is essential to gather information from various regions and healthcare levels to enhance the impact of recommendations.
