Abstract

BACKGROUND:

In renal transplant recipients, smoking is associated with a high burden of cardiovascular disease and a higher risk of graft loss. Surprisingly, the results of measurement of cotinine serum level, the gold standard for the detection of active smoking, have not been confronted with self-reported smoking history in this group. The aim of our study was to identify and characterize the smoking group of renal transplant recipients.

METHODS:

Cotinine serum level was measured and all patients were asked to fill out an anonymous questionnaire on smoking history.

RESULTS:

Out of 233 renal transplant recipients, 106 (45%) reported to be lifetime and current non-smokers: cotinine serum level was below detection limit in all; among the 127 renal transplant recipients (55%) with a lifetime history of smoking, cotinine level was diagnostic of current smoking in 32 (25%). Only 21 of the current smokers (66%) declared to the nephrologist that they had continued smoking whereas 11 (34%) claimed to be non-smokers. Current smokers were younger (P=0.01) than former smokers.

CONCLUSION:

The identification of current smokers among renal transplant recipients should start with questioning about lifetime history of smoking and if positive, measurement of cotinine serum level. Indeed up to 34% of current smokers do not acknowledge they are active smokers and would otherwise not offer to participate in programmes to stop smoking.
