Prevalence and risk factors associated with leukoplakia, hairy leukoplakia, erythematous candidiasis, and gingival hyperplasia in renal transplant recipients.
The aims of this study were to determine the prevalence of intraoral lesions in renal transplant recipients and to identify possible risk factors. The oral mucosa of 159 renal transplant recipients and 160 control patients was examined. The most common lesion in renal transplant recipients was cyclosporin-induced gingival hyperplasia (prevalence 22%) and patients with gingival hyperplasia were found to be taking significantly more cyclosporin-A than those without (p < 0.001). The prevalence of hairy leukoplakia and leukoplakia in renal transplant recipients was 11.3% and 10.7%, respectively, compared with 0% and 5.6% in the controls. Oral candidiasis was observed in 9.4% of renal transplant recipients compared with 2.5% of the controls; 3.8% of renal transplant recipients exhibited erythematous candidiasis, but this was not seen in the controls. Renal transplant recipients had a significantly increased risk of developing gingival hyperplasia (p < 0.0001), oral candidiasis (p < 0.0005), and two other conditions that have a well-established association with the immune suppression accompanying HIV infection, hairy leukoplakia (p < 0.0001) and erythematous candidiasis (p < 0.01).
