ScopusSummaryWe report a case of a previously healthy 24-year-old man with a 3-month history of gastrointestinal symptoms during exercise and also few minutes after the ingestion of cow's milk (CM) without exercise. He reported the ingestion of a blend of hydrolyzed whey and casein proteins for bodybuilding for the last 2 years. The in vivo tests showed positivity to CM, á-lactalbumin, â-lactoglobulin and casein extracts, and also to the protein supplement. The serum specific IgE was positive for CM, â-lactoglobulin and á-lactalbumin. The in vivo and in vitro tests results suggested an IgE-mediated CMA. Adult-onset CMA has been rarely reported, and to our knowledge this is the first case possibly related to bodybuilding supplements. The authors theorize that the presentation of large amounts of proteins in the gastrointestinal tract may favor sensitization.
Key wordsadult-onset cow's milk allergy; cow's milk proteins; gastrointestinal symptoms; protein supplements; bodybuilding
