OBJECTIVE: To retrospectively analyse the epidemiology, aetiology, temporal profile and outcome of lung infection following kidney transplantation. METHODS: Out of 142 consecutive renal transplant (RT) recipients who underwent live donor transplantation from June, 1990 to May, 1998, 43 (33%) had serious infection requiring hospitalisation of which 27 were pulmonary. All such pneumonia were included for retrospective analysis. All had a minimum follow up of six months (if alive) and were on triple drug immunosuppression. All had detailed and appropriate investigations for definitive diagnosis. RESULTS: The aetiological agents were Gram negative bacterial infection (2), Gram positive bacterial infection (1), nocardia (2), tuberculosis (10), aspergillosis (2), mixed bacterial and fungal infection (4), Pneumocystis (2) and unconfirmed (4). Four patients had pneumonia because of probable nosocomial exposure. Radiologically lobar/segmental pneumonia was observed in five, nodular lesion six, reticulonodular lesion eight, patchy consolidation five and pleural effusion three. Nodular pneumonias were due to aspergillosis or nocardiosis. Four patients developed secondary cavitation. Pulmonary infections were significantly associated with leucopenia (8/27) (p < 0.01) but not with renal dysfunction (creat > 2 mg%), diabetes, old age or additional immunosuppression (p > 0.05). There were 11 deaths. Mortality was related to failure to reach diagnosis (3) and delayed institution of therapy (6 patients). Pneumonia within first six months had a higher mortality (9/16) compared to late pneumonia (2/11). Immunomodulating virus (CMV 4, HEP B 2) was present in six patients of whom four succumbed. CONCLUSION: Pulmonary infection is a common and serious post-transplant infection requiring hospitalisation, is associated with high mortality. Patients with leucopenia are predisposed to these infections. Prophylaxis for Pneumocystis, Nocardia and tuberculosis needs strong consideration to reduce mortality of such infection. Nosocomial exposure risk needs careful consideration in outbreaks of opportunistic infection.
