title: [Kinetics of Bartonella spp. IgG antibodies in cat-scratch disease and in asymptomatic HIV-infected patients].
abstract: OBJECTIVE
  Our goal was to investigate the kinetics of serum IgG antibodies against Bartonella spp. in patients with cat-scratch disease and in HIV-infected indiviuals.
  
  
  METHODS
  Sequential determinations were made in seven patients with cat scratch disease and in seven HIV-infected individuals who were seropositive for this bacteria.
  
  
  RESULTS
  In five patients from each group, serum antibodies fell under the positivity threshold within two years. Two HIV coinfected patients harbored Bartonella spp. DNA in bone marrow.
  
  
  CONCLUSIONS
  These results suggest that the finding of a positive titer of serum IgG against Bartonella spp. is a marker of acute or recent infection.
