title: Effect of PI-HAART on the prevalence of oral lesions in HIV-1 infected patients. A Greek study.
abstract: OBJECTIVE
  To investigate the association between the prevalence of oral lesions and highly active antiretroviral therapy (HAART) including a protease inhibitor (PI).
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  Ninety-five consecutive patients, attending an AIDS Unit, in Greece entered the study. Fourty-four patients were receiving PI- HAART, 14 patients were on double antiretroviral therapy, and 37 patients were not receiving antiretroviral therapy at the time of oral examination. Oral lesions were diagnosed by established presumptive clinical criteria.
  
  
  METHODS
  Oral lesions were scored. CD4 counts and viral load were determined and related to the prevalence of oral lesions.
  
  
  RESULTS
  Oral lesions, and specifically oral candidiasis, were significantly reduced (P < 0.001) in patients receiving PI-HAART. Oral lesions were significantly increased in patients with CD4 counts <200 cells microl(-1) and viral load >20,000 copies ml(-1) (P < 0.001). The percentage of patients, with lesions on PI-HAART, and with CD4 < 200 and viral load >20,000 was 1.5 times lower (37.5%vs 58.8%, P < 0.001) than that of patients not receiving antiretroviral therapy, but with similar immune and viremic status.
  
  
  CONCLUSIONS
  Oral lesions were significantly reduced in patients on PI-HAART. A direct anticandidal effect of PI was suggestive and seemed to have accounted, beyond the HAART-related immune reconstitution, for the reduction of candidiasis and all other oral lesions.
