IgE, IgG and patient‐self tests during slow hyposensitization to grass pollen

Abstract: Summary Twenty‐two patients with severe hay fever unrelieved by antihistamines in previous years were slowly hyposensitized with alum‐precipitated pyridine grass pollen extracts. Their responses were objectively assessed as very good (55%), good (18%) or improved (23%). Two mechanisms were detected: (i) an increase in serum blocking activity in 59% and (ii) the prevention in 59% of the serum IgE elevation expected in the pollen season.

“… 166 An increase in the blocking IgG antibodies can be assessed by a traditional functional test with patient serum (referred to as a “patient self-test” or “P-S test”) and other means. 166 169 This is critical, as these latter antibodies compete with FcRεI-immobilized IgE antibodies for allergen binding. Specifically, stabilization of the cells capable of degranulation by reducing the chance of IgE cross-linking and increasing activation threshold reduces risk of type I hypersensitivity reactions and IgE-mediated antigen presentation by the APCs.…”
