Cow’s Milk Anaphylaxis in Children First Report of Iranian Food Allergy Registry

Abstract

Cow’s  milk  anaphylaxis is  the  most  common  food-induced  anaphylaxis in  Iranian children. The clinical and laboratory findings of cow’s milk anaphylaxis are evaluated in this study. All children who had experienced cow’s  milk anaphylaxis and had been referred to Immunology, asthma and allergy research center during a 5-year period were considered. After fulfilling a questionnaire, patients underwent measurement of total IgE and cow’s milk- specific IgE by Immunocap test and Skin prick test (SPT) with cow’s milk extract. Patients with a convincing history and one positive cow’s milk-specific IgE test (SPT or Immunocap test) and patients with both positive tests were enrolled, in this study.
Out of 49 patients, 59.2% were male. Patients’ mean age was 5 years old and their mean age at the  time of  first attack was 5.7 months  (SD =  4.3). Most  of  the  patients  have experienced more than one episode of anaphylaxis (79.5%) and in 85.7% of all cases, first attack occurred during the first year of life. Severity grading 1-5 were 2%, 6.1%, 18.4%,69.4%, 4.1% respectively. Most common manifestations were cutaneous 98%, Respiratory91.8%, Gastrointestinal  55.1%, Cardiovascular 46.9% and  neurologic  46.9%  signs  and symptoms  respectively. Twenty four  patients showed positive SPT. Mean total IgE  was 239.6±3.3  (IU/mL)  and  mean  cow’s  milk-specific IgE  was 19.28±27.2  (IU/mL).  Most patients showed reactions only after ingestion of cow’s milk or after dairy foods (81.6%).
It  is concluded  that  cow’s milk anaphylaxis may happen  early in life. Regarding the severity of attacks and remarkable number of patients with several attacks, poor knowledge about this disorder is evident.
