Recurrent pulmonary infections as the first manifestation of cow milk intolerance: a rare case report from Syria

Abstract

Abstract Cow milk protein intolerance is a common gastrointestinal condition in the first year of life. It is mainly manifested as gastrointestinal and dermatology symptoms. It rarely presents as a respiratory manifestation only without other accompanying symptoms. We report a case of a 5-month-old Syrian boy who presented with a history of recurrent acute bronchitis symptoms (cough, wheezing, tachypnea) for 3 months with no significant personal or family history. Hematological and radiographic investigations were normal. The diagnosis of cow milk intolerance was confirmed by clinical, endoscopically, and histological findings. The child was placed on amino acid hydrolysate milk with restricted cow products. The child improved significantly, and chest symptoms improved within a week of the treatment. Despite the rarity of cow milk intolerance in children with only respiratory symptoms, it should be kept in mind when the patient has recurrent pulmonary infections that are not improving on appropriate therapy.
