Association of haptoglobin phenotypes with serum levels of IgE and IgA in allergic rhinitis patients.

Background: Allergic rhinitis (AR) is an allergic disorder of the nasal tissue that underlies diseases such as sinusitis, otits and asthma. Different predisposing factors including immunological and non-immunological factors contribute to the disease pathogenesis.

Objective: To investigate association of haptoglobin (Hp) phenotypes (Hp1-1, 2-1 and 2-2) with serum immunoglobulins A and E levels in patients suffering from AR in comparison with healthy individuals.
