How allergenic are hypoallergenic formulae in patients with severe cow’s milk protein allergy?

Materials and Methods In the last 5 years (2005-2009) 7-8 patients (9-17 years) diagnosed with severe CMPA were evaluated with SPTs and cow’s milk specific -IgE in vitro determination (casein sIgE levels varied between 126 and 884 KU/L). We performed the SPTs for 17 different special formulae: 1 conventional infant formula (CMF), 3 partially hydrolysed whey/casein ones (pHF-W), 4 extensively hydrolysed casein formulae (eHF-C), 2 extensively hydrolysed whey formulae (eHF-W), 2 soya formulae (SF), 1 soya/collagen hidrolyzed mixture (HF-S) and 1 amino acid-derived formula (AaF) .In 2009, we added 3 extensively hydrolysed formulae which contained lactose (2 eHF-W and one pHF-C).
