Pneumocystis carinii pneumonia and its association with other opportunistic infections in AIDS--an autopsy report of five cases.

Pneumocystis carinii pneumonia (PCP) has been reported as one of the opportunistic pathogens in AIDS. The significance of this pathogen in AIDS is well established so that, the diagnosis of PCP in an adult simultaneously establishes the diagnosis of AIDS. This point is well emphasised in the CDC case definition of AIDS. In western literature, the occurrence of PCP in AIDS is widely reported. However, in Indian literature only sporadic case reports have been documented. This study reports 5 cases of PCP encountered amongst 34 AIDS-autopsies studied. PCP alone was present in 2 cases. It is worth noting that it was simultaneously associated with cryptococcosis, tuberculosis and CMV in 3 remaining cases, highlighting the need for extensive investigations even after establishing the diagnosis of PCP in a known full blown AIDS patient.
