Web24 mrt. 2024 · No correlation was found between results from the general allergic screening and a history with LIRs to HA fillers. Conclusion: The results suggest that neither type I nor type IV hypersensitivity plays a role in late inflammatory reactions (LIRs) to hyaluronic acid (HA) fillers. Keywords: cosmetic dermatology, allergy, cosmetic, complications. In type I hypersensitivity, B cells are stimulated (by CD4 Th2 cells) to produce IgE antibodies specific to an antigen. The difference between a normal infectious immune response and a type 1 hypersensitivity response is that in type 1 hypersensitivity, the antibody is IgE instead of IgA, IgG, or IgM. During sensitization, the IgE antibodies bind to FcεRI receptors on the surface of tissue mast cells and blood basophils. Mast cells and basophils coated by IgE antibodies are "sensitized".
