Abstract
Humoral immune capacity in recurrent E. coli upper urinary tract infection. In patients with recurrent upper urinary tract infection, humoral immune capacity was assessed from the antibody response to primary immunization with monomeric flagellin from Salmonella adelaide . Antibody producing capacity was similar to that of other hospital patients, but impaired compared with healthy subjects. No correlation was found between antibody response to flagellin and antibody response to the O antigen of the infecting organism, E. coli , but natural antibody to flagellin was higher in patients with high titers of antibody to O antigen. Deficient antibody producing capacity could not be implicated as a determinant of recurrent upper urinary tract infection.
