ABSTRACT
Being immuno-suppressed, renal allograft recipients are at increased risk of contracting various infectious complications. Pneumocystis carinii pneumonia (PCP) is one of the important opportunistic infection causing high morbidity and mortality in these patients. Majority of studies has reported the occurrence of PCP during 6 months to one year after renal transplantation. This communication describes occurrence of PCP in five renal allograft recipients 10 weeks to 72 months after transplantation. In view of elusive presentation, strong clinical and radiological suspicion followed by direct demonstration of the organisms is essential for early diagnosis and prompt treatment. These observations also indicate that PCP is an emerging opportunistic infection in immuno-compromised patients in tropical countries.
