How Allergenic are “Hypoallergenic” Formulas?
Immediate hypersensitivity reactions to cow’s milk proteins can often be found in early childhood [3–5, 7, 11]. Cow’s milk is the first proteinrich food that most infants receive after weaning. All the known antigens of cow’s milk are Proteins (Table 1). Cow’s milk contains more than 25 distinct proteins that may act as antigens in man [1, 2, 6]. The most important allergens are casein and the whey proteins β-lactoglobulin, α-lactalbumin, bovine serum albumin (BSA) and immunoglobulin. Some 60%-80% of milk-allergic patients have serum IgE to β-lactoglobulin, 60% to casein, 50% to α-lactalbumin and BSA, and up to 40% to immunoglobulin [1, 2].
