title: Low prevalence of occult HBV infection among HIV-infected patients in Southern Spain.
abstract: BACKGROUND
  The aim of this study was to assess the prevalence of occult HBV infection in HIV-positive patients in a centre in Southern Spain.
  
  
  METHODS
  The HBV serological markers were investigated in all the patients and the presence of HBV-DNA was tested by PCR in patients with isolated anti-HBc.
  
  
  RESULTS
  An isolated anti-HBc pattern was detected in 144/520 (27.7%) patients. HBV-DNA was detected in one of these patients (0.7%).
  
  
  CONCLUSIONS
  In Southern Spain, there is a low prevalence of occult HBV infection among HIV-infected patients, despite increasing immigration from endemic countries.
