 AB    Lipopolysaccharide (LPS) in the cell wall of the P. aeruginosa is a
       major factor in the pathogenicity and virulence of this organism.
       Immunotype-specific serum antibodies to this LPS antigen (ALPS) are
       usually elevated with the onset of the bacteremia, act as opsonins, are
       protective in high levels, and are significantly associated with
       improved survival. In the present study, the ability of 11 patients with
       AIDS to mount a specific ALPS response with the onset of P. aeruginosa
       bacteria was evaluated prospectively. Of the 11 patients with AIDS only
       one had a substantial ALPS response, six mounted only a marginal ALPS
       response, and four had no ALPS response to the infecting strain of the
       P. aeruginosa. These data suggest most patients with AIDS do not exhibit
       a marked antigen-specific humoral response at the onset of P. aeruginosa
       bacteremia; this has important prognostic and therapeutic significance,
       as high ALPS titers are associated with survival.
