The study of some parameters of humoral and cellular immunity in 45 pollinosis patients and 18 healthy controls, showed a deficit of humoral immunity reflected in a decrease of the IgA and IgG mean values and an increase of the IgM mean values (coefficient of correlation (r): r IgA/IgG = 0.912; r IgM/IgG = -0.316).
