[PMID: 33171749 PMCID: PMC7664415 DOI: 10.3390/ijerph17218229] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 11/02/2020] [Accepted: 11/04/2020] [Indexed: 12/11/2022]
Abstract
INTRODUCTION The administration of several classes of drugs can lead to the onset of gingival overgrowth: anticonvulsants, immunosuppressants, and calcium channel blockers. Among the anticonvulsants, the main drug associated with gingival overgrowth is diphenylhydantoin. MATERIALS AND METHODS In this study, we compared the effects of diphenylhydantoin and gabapentin on 57 genes belonging to the "Extracellular Matrix and Adhesion Molecule" pathway, present in human fibroblasts of healthy volunteers. RESULTS Both molecules induce the same gene expression profile in fibroblasts as well as a significant upregulation of genes involved in extracellular matrix deposition like COL4A1, ITGA7, and LAMB3. The two treatments also induced a significant downregulation of genes involved in the expression of extracellular matrix metalloproteases like MMP11, MMP15, MMP16, MMP24, and transmembrane receptor ITGB4. CONCLUSIONS Data recorded in our study confirmed the hypothesis of a direct action of these drugs at the periodontium level, inducing an increase in matrix production, a reduction in its degradation, and consequently resulting in gingival hyperplasia.

Lack of Association Between TGF-β1 and MDR1 Genetic Polymorphisms and Cyclosporine-Induced Gingival Overgrowth in Kidney Transplant Recipients: A Meta-analysis. Transplant Proc 2018; 49:1336-1343. [PMID: 28736004 DOI: 10.1016/j.transproceed.2017.01.080] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2016] [Revised: 01/13/2017] [Accepted: 01/24/2017] [Indexed: 12/27/2022]
Abstract
BACKGROUND Gingival overgrowth (GO) induced by cyclosporine (CsA), one of the common complications after kidney transplantation, is associated with a genetic component. However, the effect of TGF-β1 and MDR1 gene polymorphisms on the pathogenesis of CsA-induced GO remains to be determined. This study aimed to determine the association between TGF-β1 and MDR1 gene polymorphisms and CsA-induced GO in kidney transplant recipients. METHODS The Pubmed, Embase, Cochrane Library, and Chinese CNKI (China National Knowledge Infrastructure) and Wanfang databases were comprehensively searched. Data were extracted and pooled results estimated from odds ratios (ORs) and 95% confidence intervals (CIs). In addition, quality assessment and publication bias of each eligible study were examined. RESULTS Three trials focusing on the relationship between TGF-β1 +869T>C and +915G>C and 3 studies on MDR1 C3435T gene polymorphisms and the onset of CsA-induced GO were included. No association between the +869T>C polymorphism and CsA-induced GO was found in the dominant model (TT+TC vs CC: OR, 0.77; 95% CI, 0.29-2.10; P = .614). In the recessive model, no association was found between the +915G>C polymorphism and CsA-induced GO (CC vs GG+GC: OR, 1.40; 95% CI, 0.81-2.43; P = .225). And in the dominant model, no significance was calculated between MDR1 C3435T gene polymorphisms and CsA-induced GO in kidney transplant recipients (TT vs CC+CT: OR, 1.14; 95% CI, 0.62-2.09; P = .68). CONCLUSIONS No significant association exists between TGF-β1 +869T>C, and +915G>C and MDR1 C3435T gene polymorphisms and the pathogenesis of CsA-induced GO in kidney transplant recipients.

Abstract
OBJECTIVE The aim of this study was to investigate the clinical factors in relation to the cyclosporine A (CsA) induced gingival overgrowth (GO). STUDY DESIGN Seventy-three participants were assigned as GO+ and GO-. Factors including demographic, pharmacological, gingival variables and the serum cyclophilin A (CyPA) concentration were analyzed. RESULTS The occurrence of GO was 39.72%. Papillary bleeding index (PBI) had a significantly higher risk of GO than plaque index (PI), the ratio of CsA to CyPA, and serum CyPA concentration (odds ratio = 364.323, 25.791, 1.002, 0.096, respectively). The severity of GO correlated with PI, the ratio of CsA to CyPA, PBI, serum concentrations of CsA and CyPA (r = 0.366, 0.355, 0.344, 0.305, and -0.232, respectively). CONCLUSIONS Since a cross-sectional study is not able to explain whether plaque and inflammation are the cause or consequence of GO, the ratio of CsA to CyPA may be a valuable marker for predicting GO.

Abstract
BACKGROUND AND OBJECTIVE Systemic macrolide antibiotic administration has been shown to result in the elimination or reduction cyclosporine A-induced gingival overgrowth. Roxithromycin (ROX) is known to have anti-inflammatory, immunomodulatory and tissue reparative effects. This study was to evaluate the effect of adjunctive ROX therapy on cyclosporine A-induced gingival overgrowth and interleukin (IL)-1β, transforming growth factor (TGF)-β1 and vascular endothelial growth factor (VEGF) levels in gingival crevicular fluid of renal transplant patients. MATERIAL AND METHODS Thirty-one patients with clinically significant overgrowth and 16 periodontally healthy subjects were included in this randomized, double-blind, placebo-controlled, parallel-arm study. Patients received scaling and root planing (SRP) at baseline and randomized to take either ROX or placebo for 5 d. The clinical parameters, including plaque index, papillary bleeding index, probing depth and gingival overgrowth scores, were recorded. The amounts of IL-1β, TGF-β1 and VEGF in gingival crevicular fluid were detected by ELISA. Periodontal parameters as well as gingival crevicular fluid biomarker levels were evaluated at baseline and at 1 and 4 wk post-therapy. RESULTS Following SRP plus ROX and SRP plus placebo therapy, significant improvements in clinical periodontal parameters of both study groups were observed (p < 0.025). In the ROX group, adjunctive ROX therapy resulted in a greater gingival overgrowth scores reduction compared with those in the placebo group at 4 wk (p < 0.017). Initial amounts of IL-1β, TGF-β1 and VEGF for both the ROX and placebo groups were significantly higher than those for healthy subjects (p < 0.017), with no statistical difference between the two study groups. At 1 and 4 wk post-therapy, significant decreases in the amounts of IL-1β, TGF-β1 and VEGF were observed in both study groups when compared with baseline (p < 0.025), but there was no difference in the levels of IL-1β and VEGF between the two study groups. The amount of decrease in TGF-β1 levels for the ROX group was statistically significant compared to that for the placebo group at 4 wk after treatment (p < 0.017). CONCLUSION Our study indicated that combination of ROX with non-surgical therapy improves gingival overgrowth status and decreases gingival crevicular fluid TGF-β1 levels in patients with severe gingival overgrowth. The reduction of gingival crevicular fluid TGF-β1 following ROX therapy suggests an anti-inflammatory/immunomodulatory effect of ROX on the treatment of cyclosporine A-induced gingival overgrowth.

Abstract
OBJECTIVE Interleukin-10 (IL-10) is an anti-inflammatory cytokine whose genetic polymorphisms are associated with the production of IL-10 and the susceptibility to periodontal diseases. The aim of this study was to investigate the possible association of IL-10 single nucleotide polymorphisms (SNPs) and cyclosporin A (CsA)-induced gingival overgrowth (GO) in renal transplant patients in a Chinese population, taking into account subgingival microbiota as additional variables. MATERIAL AND METHODS A total of 202 patients were dichotomized into two groups: 122 with GO and 80 without GO. The IL-10-1082 SNP, -819 SNP and -592 SNP were measured using an allele-specific PCR method. The levels of subgingival bacteria were measured by real-time PCR. Genotype and allele frequencies were analyzed using the Chi-square test and logistic regression analysis. RESULTS The frequency of IL-10-819TT (-592AA) genotype was statistically higher in patients with GO than that in patients without GO (P<0.05). Multiple logistic regression analysis demonstrated that the prevalence of GO is not dependent on age, gender, and pharmacological variables, being significantly associated with the carriers of ATA haplotype (OR=2.425, 95%CI=1.214-4.845, P=0.012). Moreover, ATA positive carriers in the GO group presented significantly higher levels of Porphyromonas gingivalis and Treponema denticola than those negative carriers. CONCLUSIONS Our results show that IL-10-819TT (-592AA) genotype and ATA halpotype are associated with susceptibility to CsA-induced GO. Meanwhile, ATA haplotype is associated with a higher detection of P. gingivalis and T. denticola in GO patients, and may increase the risk of developing GO.

Abstract
UNLABELLED BACKGROUD AND OBJECTIVE: Genetic factors may influence the colonization of pathogenic bacteria, therefore increasing the risk for the initiation and development of periodontal disease. The present study was carried out to investigate the association of CD14-260 polymorphisms, subgingival microbiota, and gingival crevicular fluid (GCF) cytokine levels with cyclosporine A (CsA)-induced gingival overgrowth (GO) in renal transplant patients. MATERIAL AND METHODS A total of 204 patients were dichotomized into two groups: 124 with GO and 80 without GO. The CD14-260 polymorphisms were measured using an allele-specific PCR method. The levels of periodontal pathogens were determined by real-time PCR of subgingival samples. GCF levels of IL-1β and sCD14 were detected by ELISA. RESULTS The frequency of CD14-260 genotype CT + TT was found to be similar in both groups. Patients with GO presented increased prevalence of Pg, Td, and Tf (red complex) and significantly higher levels of interleukin -1β than those without GO. Patients with GO carrying CT + TT genotypes were found to have higher frequencies of Pg, Td, and Tf than those carrying the CC genotype. Furthermore, in the presence of red complex, CT + TT genotypes were associated with higher interleukin -1β levels and severe GO. Multiple logistic regression analysis demonstrated that the severity of GO is not dependent on age, gender and pharmacological variables, being only associated with CD14-260 genotype and red complex periodontopathogens. CONCLUSION No association between CD14-260 polymorphisms and the prevalence of GO was revealed in renal transplant patients administered CsA. However, CD14-260 CT + TT genotypes are associated with the prevalence of red complex periodontopathogens in patients with GO, and may thus play some role in the development of severe CsA-induced GO.

Abstract
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 a medical problem. We studied the determination of association between TGF-β1 (TGFB1) gene polymorphism and gingival overgrowth in kidney transplant patients medicated with cyclosporin A. METHODS Eighty-four 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 it 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.

Abstract
OBJECTIVE Interleukin-6 (IL-6) may be involved in drug-induced gingival overgrowth (GO). The present study was conducted to assess the association between IL-6 (-174 G/C) gene polymorphism and GO in renal transplant recipients under cyclosporine (CsA), tacrolimus (Tcr), or sirolimus (Sir)-based regimens. METHODS Within an eligible population, 45 unrelated subjects were selected for each CsA, Tcr, and Sir group, totaling a sample of 135 subjects. GO was visually assessed and subjects were assigned as controls (non-responders) or cases (responders) in a post hoc definition. IL-6 gene polymorphism was assessed using the polymerase chain reaction amplification and digestion. The distribution of genotypes and allele frequencies in responders and non-responders were compared using the Chi-squared test. RESULTS The number of responders was 27 (60.0%), 13 (28.9%), and 7 (15.6%) in the CsA, Tcr, and Sir groups, respectively. No differences could be observed at frequencies of -174GG, -174CG, and -174CC genotypes when comparing responders to non-responders in the CsA, Tcr, and Sir groups. Similar to genotypes, allele frequencies showed no differences between responders and non-responders in all groups. CONCLUSIONS No association between IL-6 (-174 G/C) gene polymorphism and gingival overgrowth was observed in renal transplant recipients under CsA, Tcr, or Sir-based immunosuppressive maintenance regimens.

Abstract
AIM Levels of interleukin-1alpha (IL-1alpha) are elevated in periodontal inflammation. IL-1A gene polymorphisms are associated with inflammatory diseases. This study aimed to investigate IL-1A gene polymorphism in Cyclosporin A (CsA)-treated renal transplant patients and investigate the association between this polymorphism and gingival crevicular fluid (GCF) levels of several cytokines. MATERIALS AND METHODS Fifty-one renal transplant patients on CsA treatment (25 with and 26 without gingival overgrowth) and 29 healthy controls were recruited for the study. Demographic, pharmacological and periodontal parameters were recorded and gingival overgrowth was assessed. RESULTS Multiple regression analysis showed that genotype was significantly associated with gingival overgrowth (p=0.02). Carriage of the IL-1A (-889) T allele was strongly protective [95% confidence interval (CI): 0.046-0.77], although not significantly associated with IL-1alpha protein levels in GCF. IL-1alpha, IL-1beta and IL-8, but not IL-6, were detected in GCF of CsA-treated patients, but none of them was significantly associated with gingival overgrowth. CONCLUSIONS This study is the first to associate a gene polymorphism as a risk factor for CsA-induced gingival overgrowth in renal transplant patients, demonstrating that IL-1A polymorphism might alter individual susceptibility to CsA. However, there was no association between GCF cytokine levels and the presence of gingival overgrowth or patient IL-1A genotype.

Abstract
BACKGROUND Cyclosporin A (CsA) induces gingival overgrowth (GO) in patients who seem to be prone to this disorder. It is still impossible to determine which patients will develop GO. Patients treated with the new immunosuppressive drug tacrolimus seem not to have GO. The aims of this study were to investigate transforming growth factor-beta1 (TGF-beta1) gene polymorphisms in renal transplant recipients treated with CsA or tacrolimus and to establish an association between these polymorphisms and TGF-beta1 plasma concentration and the incidence of GO. METHODS The examined group consisted of 134 renal transplant recipients. Ninety-two underwent CsA treatment (50 with and 42 without GO), and 42 underwent tacrolimus treatment. Age, gender, time after transplantation, calcineurin inhibitor total dosage, number of teeth, and sulcus bleeding index were analyzed. TGF-beta1 plasma levels were estimated in 60 CsA- and 30 tacrolimus-treated patients. Two biallelic polymorphisms of the TGF-beta1 gene were studied at codon 10 (at position +869) and at codon 25 (at position +915) in patients from the examined group and in 108 healthy volunteers (the control group). RESULTS The distribution of the high, intermediate, and low TGF-beta1 producer phenotypes was comparable in all the studied groups and in the healthy controls. The high producer phenotype was more frequent in patients with GO. TGF-beta1 levels in the CsA group showed correlation with the phenotypes. The lowest incidence of GO was observed in the 10C/C genotype, whereas the highest was observed in the 10T/C genotype. CONCLUSION High and intermediate TGF-beta1 producer phenotypes and heterozygous genotype 10T/C might be considered risk factors for GO in patients treated with CsA.

Abstract
BACKGROUND Cyclosporin (CsA) and tacrolimus (FK-506) are immunosuppressive drugs that specifically inhibit T-cell activation via calcineurin inhibition. Gingival overgrowth is a common side effect following the administration of CsA. The severity of gingival overgrowth seen in patients taking FK-506 is less than that observed with CsA. Little is known about the involvement of saliva in drug-induced gingival overgrowth. The purpose of this study was to investigate the salivary contents of tumor growth factor beta1 (TGF-beta1), epidermal growth factor (EGF), and interleukin-6 (IL-6) as well as the hystometry of gingival tissue obtained from rats treated with either FK-506 or CsA. METHODS For 30 or 60 days rats received daily subcutaneous injection doses of either CsA or FK-506 (10 mg/kg). The concentrations of TGF-beta1, EGF, and IL-6 in saliva were determined by enzyme-linked immunosorbent assay, and after histological processing, the oral epithelium and connective tissue were assessed at the region of the lower first molars. RESULTS The levels of TGF-beta1, EGF, and IL-6 in saliva were not significantly altered by any of the treatments after 30 days. After 60 days of treatment with CsA, gingival overgrowth and significant increase in salivary TGF-beta1, EGF, and IL-6 concentrations were observed; no statistically significant changes were induced by FK-506. CONCLUSION Within the limits of this experimental study, it can be concluded that CsA, but not FK-506, induced gingival overgrowth associated with an increase of the salivary levels of the cytokines TGF-beta1, EGF, and IL-6.

Abstract
The polymorphism at position 25 of the gene encoding transforming growth factor-beta1 (TGF-beta1), which changes the amino acid sequence of the signal peptide sequence (arginine to proline), is causing a variation in TGF-beta1 production. The homozygous genotype (Arg25Arg) is associated with higher TGF-beta1 production than the heterozygous (Arg25Pro) genotype. Therefore, the possible involvement of this genetic variation in the TGF-beta1 gene for induction and progression of various diseases is under close investigation. At present, several labor-intensive established assays ranging from amplification refractory mutation system (ARMS)-PCR methodologies, sequence specific oligonucleotide probing (SSOP), restriction fragment length polymorphism (RFLP) analysis, 5' nuclease assays, and specialized fingerprinting protocols are applied to analyze the polymorphism in question. We developed a novel approach for analyzing this polymorphism in a LightCycler system and determined the allele frequency distributions between patients with different degrees of hepatic fibrosis induced by chronic hepatitis C virus infection. In patients with severe hepatic fibrosis (METAVIR-score 3-4), the Pro25 allele was twice as frequent compared to patients with mild fibrosis (METAVIR-score 0-2). However, we found no association of necroinflammatory activity and genotype distribution. This suggests that the stage of hepatic fibrosis, rather than the grade (inflammation), is influenced by the presence of proline at codon 25 in patients with chronic hepatitis C.

Abstract
BACKGROUND It has been demonstrated that cyclosporin A (CyA) blocks the immune system, acts on cytoskeleton and stimulates the production of extracellular matrix (ECM) and transforming growth factor-beta1 (TGF-beta1). This cytokine, such as transforming growth factor-alpha (TGF-alpha), induces deposition of glycosaminoglycans (GAG), proteoglycans and collagen fibres in the ECM. METHODS In this work, we examined the effect induced by CyA, TGF-beta1 and TGF-alpha on cultures of healthy and overgrown human gingival fibroblasts in order to evaluate the glycosaminoglycan, cytoskeletal changes and the behaviour of fibroblasts after concanavalin A (Con A) treatment. Moreover, we examined gingival biopsies by Alcian blue histochemical staining and electron transmission microscopy. RESULTS Total and extracellular sulphated GAG in overgrown gingiva specimens and in derived fibroblast cultures treated with CyA and cytokines were significantly higher than controls. The action of cytokines was increased (P < or = 0.01) compared with CyA with a greater effect of TGF-alpha in comparison with TGF-beta1; the electron microscopy showed ECM accumulation. The agglutinations showed the heterogeneity of fibroblast populations. CONCLUSIONS Stimulation with Con A showed that the fibroblast population had cell surface heterogeneity, and could respond in a different way to both CyA and cytokine stimulus. Moreover, increased synthesis of GAG in overgrown gingiva compared with synthesis in normal fibroblasts before CyA treatment suggests a possible genetic origin of damage. As not all CyA-treated patients develop gingival overgrowth, a genetic predisposition may explain the different responses of gingival fibroblast populations.

Abstract
OBJECTIVE To determine if local, gingival crevicular fluid (GCF) levels of TGFbeta1 were altered in drug-induced gingival overgrowth. PATIENTS AND METHODS GCF samples were collected on Periopaper strips from 45 renal transplant recipients who had been medicated with cyclosporin or cyclosporin in combination with other putative overgrowth-inducing drugs for a minimum of 6 months. Twenty-two subjects had gingival overgrowth while the other 23 patients showed no signs of gingival changes and constituted the medicated control group. Non-medicated controls consisted 20 periodontally healthy individuals who had never taken overgrowth-inducing drugs. GCF levels of TGFbeta1 and alkaline phosphatase, a marker of inflammation, were determined by enhanced chemiluminescence ELISA and enzyme activity assays, respectively. RESULTS TGFbeta1 levels in GCF from overgrowth and non-overgrowth sites in overgrowth sufferers did not differ. However, there were significant differences in median concentration (P = 0.001) and GCF levels of TGFbeta1 per sample (P = 0.05) between study groups with overgrowth patients having higher amounts per sample and lower concentrations than medicated and healthy controls. Median levels of alkaline phosphatase per GCF sample differed between site (P = 0.01) with higher levels present at overgrowth sites. Despite this, the concentration of enzyme in GCF did not differ between site or patient group. CONCLUSIONS GCF TGFbeta1 detected in overgrowth patients could reflect a higher level of gingival inflammation because of difficulties in plaque control consequent on the development of overgrowth. However, the higher local levels of total TGFbeta1 in overgrowth patients could indicate that it is a risk factor for developing gingival overgrowth.

Abstract
BACKGROUND A cohort study for Caucasians aged 65 years or older demonstrated a marked breast cancer risk reduction for those with the CC genotype of transforming growth factor B1 (TGF B1) T29C polymorphism. This is a prevalent case-control study to examine the reported risk reduction for Japanese women. PATIENTS AND METHODS A total of 232 histologically diagnosed breast cancer patients who visited Aichi Cancer Center Hospital between June 1999 and March 2000 were enrolled. The controls were 172 female outpatients without cancer at the same hospital. DNA was extracted from peripheral blood, and TGF B1 genotype was determined by PCR-CTPP. RESULTS The genotype frequency was 23.7% for TT, 49.2% for TC, and 27.1% for CC among controls, and 28.9%, 46.1%, and 25.0%, respectively, among cases. Age-adjusted odds ratio (OR) relative to the TT genotype was 0.81 (95% confidence interval, 0.50-1.31) for the TC genotype and 0.77 (0.45-1.34) for the CC genotype. For premenopausal women, the CC genotype was significantly associated with reduced risk of breast cancer in comparison with the TT genotype (OR=0.45, 0.20-0.98). The association was not observed for postmenopausal women (OR=1.40, 0.64-3.08). CONCLUSION The present study showed risk reduction for Japanese premenopausal women with the CC genotype, but not for postmenopausal Japanese women.

Abstract
BACKGROUND Unlike other cancers, breast cancer does not occur at increased frequency in renal transplant patients but fibroadenomata may be more common as a result of exposure to cyclosporin. In order to determine the incidence of benign breast disease in renal transplant patients at Monash Medical Centre, current female patients were studied. METHODS The study was divided into two parts: (i) a retrospective review of those who presented with clinically detectable breast lumps; and (ii) mammographic screening of current female transplant patients who had been transplanted for more than 1 year. RESULTS In the retrospective study there were 11 patients with 16 breast lumps among a total of 85 patients. All were confirmed by biopsy. The mean age at diagnosis of breast lumps was 41.5 years (range 25-70 years). The mean time to presentation was 3.5 years after transplantation. Nine out of 11 patients had benign breast disease including fibroadenoma (six patients), fibrocystic disease (two patients) and intraductal papillomatosis (one patient). Two patients had breast cancer. Five of the patients with fibroadenoma had multiple lumps and a recurrent course. All patients with fibroadenomata had received cyclosporin. In the second part, 54 patients were further screened. The mean duration of transplantation was 6.4 years (range 1.25-18.5 years). Eighty-seven per cent of the patients had received cyclosporin, and 80% had a negative (normal) study. Seven of 54 had abnormalities including cysts and calcification, of whom two patients had fibroadenomata. Four patients had 'dense mammograms', all of whom received cyclosporin as a part of their immunosuppression. No breast cancer was detected during the study. CONCLUSION The incidence of benign breast disease in the female transplant patients studied was far greater then the general population. The increase in fibroadenomata, in particular, may relate to the use of cyclosporin.
