Résumé

BACKGROUND: The incidence of gingival overgrowth among renal transplant patients treated with cyclosporine A ranges from 13 to 84.6%, and the overgrowth is not only esthetic but also medical problem. The study was aimed at determination of association between TGF- β1 gene (TGFB1) polymorphism and gingival overgrowth in kidney transplant patients medicated with cyclosporin A. METHODS: 84 kidney transplant patients with gingival overgrowth and 140 control transplant patients without overgrowth were enrolled into the case control study. TGFB1 polymorphism was determined using the PCR-RFLP assay for +869T>C in codon 10 and +915G>C in codon 25 as well as TaqMan real-time PCR assays for promoter −800G>A and −509C>T SNPs. RESULTS: In kidney transplant patients suffering from gingival overgrowth mean score of gingival overgrowth was 1.38±0.60, whereas in control subjects was 0.0. The patients with gingival overgrowth were characterized by similar distribution of TGFB1 genotypes and allele in comparison to subjects without gingival overgrowth. Among 16 potentially possible haplotypes of TGFB1 gene, only four were observed in the studied sample of kidney transplant patients: G_C_T_G, G_T_C_G, G_C_C_C, and A_C_T_G, with similar frequency in patients with and without gingival overgrowth. CONCLUSION: No association between the TGFB1 gene polymorphism and gingival overgrowth was revealed in kidney transplant patients administered cyclosporine A.
