title: Summary of track B: clinical science.
abstract: OBJECTIVE
  To review Track B on clinical science. Major topics covered were quantitative HIV-1 plasma RNA measurement, combination antiretroviral therapy, protease inhibitors, treatment of primary HIV-1 infection, HIV-1 drug resistance, future use of antiretroviral drugs, paediatric HIV-1 infection, opportunistic infections and HIV/AIDS in developing countries. QUANTITATIVE HIV-1 PLASMA RNA MEASUREMENT: Quantification of HIV-1 RNA is a predictor of progression of immune deficiency and death in HIV-infected adults and children, and is useful in monitoring response to antiretroviral therapy.
  
  
  METHODS
  Combination antiretroviral therapy is now the standard of care, although questions about optimal starting time and the best initial regimen remain unresolved. Protease inhibitors are a powerful new class of antiretroviral agents which in combination with other drugs can produce profound reductions in plasma HIV-1 RNA levels. Trials are in progress of combination antiretroviral therapy, including protease inhibitors, in persons recently infected with HIV-1 to assess the feasibility of permanent suppression or eradication of HIV-1. Adherence to therapy and drug resistance will become increasingly important subjects.
  
  
  CONCLUSIONS
  The genuine improvements in patient management are out of reach to the majority of the world's HIV-infected persons, a conclusion with implications which dampened the optimism generated by the conference.
