Abstract
Background Recent research has shown that cow's milk protein intolerance (CMPI) often persists beyond 4 years of age. Aims To evaluate the clinical and immunological characteristics of a group of infants with persistent CMPI. Patients and methods Twelve infants (6 m, 6f) with persistent CMPI were followed up from birth until a median age of 5 years. The patients underwent CMP challenge each year to evaluate CMP‐tolerance. As controls we followed 26 infants (12 m, 14 f) with CMPI that resolved within 1–2 years. Results A family history of atopic disease was found in 10/12 patients with persistent CMPI and in 10/26 controls (P < 0.01). Clinical presentation changed over time: at onset symptoms were prevalently gastrointestinal, while at the end of the study there was an increased frequency of wheezing and constipation and a higher frequency of delayed reactions to CMP‐challenge than at study commencement (9/12 vs 2/12; P < 0.007). 11/12 infants with persistent CMPI and 3/26 controls (P < 0.0001) presented multiple food intolerance. During the observation period 9/12 infants with persistent CMPI and 2/26 controls showed atopic disease: asthma, rhinitis, eczema (P < 0.0001). Conclusions Persistent CMPI forms are characterized by: (a) considerable importance of familial atopic disease; (b) change in CMPI manifestations over time and more prolonged delay between CMP consumption and manifestation of symptoms; (c) very high frequency of multiple food intolerance and allergic diseases.Keywords
