Primary Outcome Measures:
  • Documented PCP infection [ Time Frame: 12 weeks. ] [ Designated as safety issue: No ]
    Documented Pneumocystis carinii pneumonia infection: defined as documentation of Pneumocystis from a properly obtained specimen (induced sputum, bronchoalveolar lavage, or biopsy) in a patient with clinical manifestations compatible with PCP.

Secondary Outcome Measures:
  • PCP-related mortality [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    PCP-related mortality at the end of week 12.

  • All cause mortality [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    All cause mortality at the end of week 12.

  • Other infections [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Infections other than PCP throughout the study period.

  • PCP-related hospitalization [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    PCP-related hospitalization throughout the study period.
