title: [Quantification of the levels of p24 antigen and antibodies in human immunodeficiency virus infection].
abstract: BACKGROUND
  Quantification and clinical evaluation of p24 antigen and anti-HIV antibody levels.
  
  
  METHODS
  Follow up of 13 HIV infected patients (53 sera) by determination of p24 antigen, total anti-HIV antibodies, anti-p24 and anti-env antibodies by ELISA and their semiquantitation. IgG and IgM class antibody determination by immunoblot techniques.
  
  
  RESULTS
  The highest levels of p24 have been found in WR 1 and WR 6 stages. Commonly accepted serologic pattern has not been found in 100% of our cases. Western-blot is more sensitive for the detection of anti-p24 antibodies.
  
  
  CONCLUSIONS
  p24 antigen appearance and a decrease in anti-p24 antibody level is related to a worse clinical prognosis. p24 antigen quantification is a usefull test for monitoring AZT therapy in patients suffering from AIDS.
