Cow's milk protein allergy (CMPA) is the most frequent cause of food allergy in the first months of life. Despite the fact that there are different guidelines and recommendations on the management of children with CMPA, there continues to be great variability in diagnostic and therapeutic criteria in Latin America. The Food Allergy Working Group of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition summoned a group of Latin American experts to reach a consensus and formulate a document to unify diagnostic and therapeutic criteria for CMPA. Three teams were formed, each with a coordinator, and the members of each team developed a series of statements for their corresponding module: a) clinical manifestations and diagnosis; b) diagnostic tools, and c) treatment. A search of the medical literature was carried out to support the information presented in each module and 28 statements were then selected. The statements were discussed, after which they were evaluated by all the experts, utilizing the Delphi method. Their opinions on statement agreement or disagreement were anonymously issued. The final statements selected were those with above 75% agreement and their corresponding recommendations were formulated, resulting in the document presented herein. Resumen: La alergia a las proteínas de leche de vaca (APLV) constituye la causa más frecuente de alergia alimentaria en los primeros meses de vida. A pesar de la existencia de diferentes guías y recomendaciones sobre el manejo de niños con APLV, en Latinoamérica sigue observándose una gran variabilidad de criterios diagnósticos y terapéuticos. El grupo de trabajo de Alergia Alimentaria de la Sociedad Latinoamericana de Gastroenterología, Hepatología y Nutrición Pediátrica se dio a la tarea de convocar a un grupo de expertos de la región, realizar un consenso y elaborar un documento con el objetivo de unificar criterios diagnósticos y terapéuticos para APLV. Se dividió el grupo en tres equipos bajo un coordinador para cada equipo, y los miembros de cada grupo formularon una serie de enunciados correspondientes a uno de tres módulos diferentes: a) manifestaciones clínicas; b) herramientas diagnósticas, y c) tratamiento. Se buscó la información en la literatura médica para sustentar la información de cada uno de ellos, y posteriormente se seleccionaron 28 enunciados, los cuales fueron discutidos y posteriormente evaluados por todos los expertos, a través de método Delphi, quienes emitieron su opinión sobre acuerdo o desacuerdo sobre las mismas de forma anónima. Todos los enunciados obtuvieron porcentajes de acuerdo mayores al 75%, por lo que permanecieron, y con base en ellos se elaboraron las recomendaciones y se presentan.
