A comparative immunological study of vasomotor rhinitis and pollinosis.
Differentiation between pollinosis and vasomotor rhinitis creates great diagnostic difficulties. The aim of this study was to conduct comparative immunological clinical studies contrasting these two distinct diseases. Thirty-one subjects with untreated pollinosis and 29 subjects with untreated symptoms of rhinitis were tested, determining their T and B lymphocyte counts and the counts of their subpopulations, the levels of immunoglobulin A, M, G, D and E, both separately and in total, and levels of both basal and whole histamine. The control group was comprised of 30 healthy subjects. The results of this study show that these two diseases differ from each other (p < 0.05) in the recorded levels of basal histamine, total IgE, and IgG, IgM and IgD, as well as the count of T-RFC lymphocytes, T lymphocytes with receptors for Fc IgG and B lymphocytes with superficial receptors for IgG. The most useful laboratory methods for diagnosing the difference between pollinosis and vasomotor rhinitis appear to be the determination of levels of basal histamine and IgD in the blood.
