Abstract
The subject invention pertains to methods of treating immunocompromised patients, such as individuals infected with HIV, that exhibit elevated levels of IgA relative to IgG. The use of IgA-binding compositions immobilized onto a support matrix to extracorporeally remove IgA molecules from a sample or biological fluid for therapeutic purposes is provided by the present invention. The subject invention further pertains to novel polypeptides which bind in a specific manner to human IgA. The polypeptides of the present invention comprise an IgA-binding region from an IgA-binding protein of Group B streptococcal bacteria.
