Nocardiosis in tropical renal transplant recipients.

Background: The epidemiology of nocardiosis in the tropics among renal transplant recipients has not been reported.

Methods: An evaluation of nocardiosis for 30 yr in one of the large transplant centres in South Asian region.

Results: Of the 1968 patients who received primary renal allografts at Christian Medical College & Hospital, 27 patients developed nocardiosis over 30 yr. Early nocardiosis (2 yr). Seventeen patients (63%) had two or more associated post-transplant infections, of whom 10 had tuberculosis. Mortality in these patients was associated with chronic liver disease.

Conclusions: Nocardiosis manifests earlier (<2 yr) in CsA treated patients who have chronic liver disease. Among renal transplant recipients of the tropics nocardiosis is a marker of a high susceptibility to tuberculosis and other infections, the association with tuberculosis is stronger in those developing early nocardiosis (<2 yr). Chronic liver disease is a risk factor for death in patients with nocardiosis especially when associated with tuberculosis. This report constitutes the largest single centre experience among renal transplant recipients.
