title: [Seroepidemiology of Bartonella henselae infection in HIV-infected patients].
abstract: BACKGROUND
  Bartonella henselae infections are closely related to numerous clinical infections of growing interest in Spain. Since immunosuppressed patients are a potential risk group for infection by this bacteria, the aim of the present was to study the seroepidemiology of B. henselae infection in a risk group (patients with HIV infection) and in a control group (donors).
  
  
  METHODS
  In October, 1997, antibodies versus B. henselae were determined at different dilutions (cut off > or = 1:64) by immunofluorescence in 52 patients with HIV infection and 85 donors. An epidemiologic study included age, sex, smoking, alcohol intake, INVDA, HIV infection, AIDS stage, cutaneous anergy, CD4 lymphocyte count, antiretroviral treatment and chemoprophylaxis versus P. carinii.
  
  
  RESULTS
  Nine of the patients with HIV infection (17.3%) and five donors (5.88%) presented titers > or = 1:64 with no significant differences (p = 0.06) (adjusted OR: 1.7; CI 95%: 0.34-8.54). Moreover, multiple logistic regression analysis did not show any risk or protection factor associated with B. henselae infection in patients with HIV infection.
  
  
  CONCLUSIONS
  A high level of seroprevalence of antibodies versus B. henselae was observed in patients with HIV infection. No risk or protection factors associated with B. henselae infection in patients with HIV infection were found.
