Abstract
Amlodipine is a widely used calcium channel blocker associated with gingival enlargement. The effects of amlodipine on gingival enlargement vary depending on the duration of drug use and the dose of the active substance. This report presents a 56-year-old male hypertensive patient who had been using amlodipine (5 mg/day orally, single dose) for the last two years. He presented with diffuse gingival enlargement, complaining of gingival swelling and bleeding. This case report demonstrates the treatment of gingival enlargement with a novel 445-nanometer (nm) blue light diode laser after drug change and oral hygiene, which resulted in permanent and satisfactory clinical results.

Impact of Immunosuppressive Drugs on Fibroblasts: An In Vitro Study. J Clin Med 2022; 11:jcm11113107. [PMID: 35683494 PMCID: PMC9181118 DOI: 10.3390/jcm11113107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 05/17/2022] [Accepted: 05/24/2022] [Indexed: 12/04/2022] Open
Abstract
Background: The aim of this study was to compare the direct impact of different agents for immunosuppressive therapy on mouse fibroblasts as a possible cause of drug-induced gingival overgrowth (DIGO). Methods: 3T3 mouse fibroblasts were cultivated in cell-specific media (2 × 104 cells/mL) and treated for 6, 24, 48 and 72 h with one of three immunosuppressive drugs (IsDs): cyclosporin a (CsA), tacrolimus (TaC) and sirolimus (SiR). Different concentrations (10−750 ng/mL) were used to mimic serum levels under active immunosuppressive therapy conditions. Cell population characteristics (cell number, viability and morphology) were assessed using computer-assisted cell analysis. Expression of pro-collagen type I carboxy-terminal propeptide (PICP) was identified using an ELISA assay. Results: The influence of IsDs on the biological status of 3T3 fibroblasts was time- and dose-dependent. Comparing CsA and TaC, the total cell amount was enhanced using concentrations in the range of 10−150 ng/mL (p > 0.05). In contrast, treatment with SiR resulted in a decrease in the average cell number (p < 0.01). PICP and cell diameter of fibroblasts were not susceptible to IsD treatment (p > 0.05). Conclusions: Our results revealed time-dependent effects of IsDs, with distinct influences on cell number. The cell morphology and the PICP balance of the investigated fibroblast cell line remained unaffected. Hence, the potential role of IsDs is not a unilateral mechanism of action but rather a multifactorial process.

Abstract
Drug-induced gingival overgrowth (DIGO) is a pathological growth of gingival tissue, primarily associated with calcium channel blockers and immunosuppressants. Consequently, it is mainly seen in cardiovascular and transplanted patients. Nifedipine remains the main calcium channel blocker related to the development of this unpleasant side-effect. As for immunosuppressants, cyclosporin is the leading causative agent, whereas other drugs from this drug-group, including tacrolimus, have better safety profiles. Accumulated collagen with inflammatory infiltrates is the histological hallmark of this condition. Several factors are involved in the pathogenesis and can increase the risk, such as male gender, younger age, pre-existing periodontal inflammation, and concomitant use of other DIGO-inducing medications. Patients with DIGO may experience severe discomfort, trouble with speech and mastication, pain, and teeth loss, aside from cosmetic implications. Furthermore, these patients also have an increased risk for cardiovascular diseases. The interdisciplinary approach and cooperation with dental care experts are necessary for patient management. Treatment includes discontinuing the drug and switching to one with a better profile, improving oral hygiene, and surgical removal of enlarged tissue. Recognizing the potential of commonly used medications to cause DIGO and its effect on patients' health is necessary for early detection and adequate management of this complication.

Abstract
BACKGROUND Long-lasting diabetes mellitus may lead to numerous pathologies in the oral cavity. The aim of the study was to assess the condition of the oral cavity, caries intensity, salivary parameters, and incidence of oral fungal infections in patients with type 1 diabetes (T1D) and end-stage renal disease (ESRD) after kidney transplantation (KTx) or simultaneous kidney and pancreas transplantation (SPK). METHODS Twenty-one patients after SPK, 18 T1D patients after KTx, and 14 kidney recipients without diabetes (control group) were included in the study. Donor sources complied with Helsinki Congress and the Declaration of Istanbul. RESULTS Approximal plague index in SPK (80% [68%-90%]) was comparable to KTx (80% [37.5%-92.5%]) but higher than in control group (46% [35%-50%]). All 3 groups did not differ in terms of decayed-missing-filled tooth index: 22.3 ± 4.8 vs 22.5 ± 4.5 vs 19.1 ± 4.9, respectively. Normal saliva resting secretion and consistency were more common in SPK (71.4% and 52%, respectively) than in KTx (27.8% and 50.0%, respectively). Stimulated saliva volume in the SPK, KTx and controls, pH value, and buffering capacity were comparable. In KTx higher incidence of Candida albicans infection (55.6%) compared with SPK (23.8%) and controls (no infection) was observed. CONCLUSIONS Simultaneously transplanted pancreas improves salivation and reduces the incidence of oral fungal infections in T1D kidney recipients. The severity of caries is higher and oral hygiene is worse in T1D kidney recipients compared with patients after KTx without diabetes.

Abstract
OBJECTIVE This review proposes revisions to the current classification system for gingival diseases and provides a rationale for how it differs from the 1999 classification system. IMPORTANCE Gingival inflammation in response to bacterial plaque accumulation (microbial biofilms) is considered the key risk factor for the onset of periodontitis. Thus, control of gingival inflammation is essential for the primary prevention of periodontitis. FINDINGS The clinical characteristics common to dental plaque-induced inflammatory gingival conditions include: a) clinical signs and symptoms of inflammation that are confined to the gingiva: b) reversibility of the inflammation by removing or disrupting the biofilm; c) the presence of a high bacterial plaque burden to initiate the inflammation; d) systemic modifying factors (e.g., hormones, systemic disorders, drugs) which can alter the severity of the plaque-induced inflammation and; e) stable (i.e., non-changing) attachment levels on a periodontium which may or may not have experienced a loss of attachment or alveolar bone. The simplified taxonomy of gingival conditions includes: 1) introduction of the term "incipient gingivitis;" 2) a description of the extent and severity of gingival inflammation; 3) a description of the extent and severity of gingival enlargement and; 4) a reduction of categories in the dental plaque-induced gingival disease taxonomy. CONCLUSIONS Dental plaque-induced gingival inflammation is modified by various systemic and oral factors. The appropriate intervention is crucial for the prevention of periodontitis.

Abstract
Chronic kidney disease (CKD) is recognized as an irreversible reduction of functional nephrons and leads to an increased risk of various pathological conditions, including cardiovascular disease and neurological disorders, such as coronary artery calcification, hypertension, and stroke. In addition, CKD patients have impaired immunity against bacteria and viruses. Conversely, kidney transplantation (KT) is performed for patients with end-stage renal disease as a renal replacement therapy. Although kidney function is almost normalized by KT, immunosuppressive therapy is essential to maintain kidney allograft function and to prevent rejection. However, these patients are more susceptible to infection due to the immunosuppressive therapy required to maintain kidney allograft function. Thus, both CKD and KT present disadvantages in terms of suppression of immune function. Periodontal disease is defined as a chronic infection and inflammation of oral and periodontal tissues. Periodontal disease is characterized by the destruction of connective tissues of the periodontium and alveolar bone, which may lead to not only local symptoms but also systemic diseases, such as cardiovascular diseases, diabetes, liver disease, chronic obstructive pulmonary disease, and several types of cancer. In addition, the prevalence and severity of periodontal disease are significantly associated with mortality. Many researchers pay special attention to the pathological roles and clinical impact of periodontal disease in patients with CKD or KT. In this review, we provide information regarding important modulators of periodontal disease to better understand the relationship between periodontal disease and CKD and/or KT. Furthermore; we evaluate the impact of periodontal disease on various pathological conditions in patients with CKD and KT. Moreover, pathogens of periodontal disease common to CKD and KT are also discussed. Finally, we examine the importance of periodontal care in these patients. Thus, this review provides a comprehensive overview of the pathological roles and clinical significance of periodontal disease in patients with CKD and KT.

Abstract
Gingival overgrowth is a major and frequent unwanted effect accompanying the chronic usage of antihypertensive, anticonvulsant, and immunosuppressant drugs. The expression and the severity of this tissue-specific condition are influenced by a variety of factors, mainly drug and periodontal variables. Such increased volume of gingiva may compromise normal oral functions, aesthetics in addition to the patients' ability to practice optimal oral hygiene. The management of gingival overgrowth includes nonsurgical approach, surgical approach, or both of them for severe cases of gingival overgrowth as well as drug withdrawal. This case report illustrates a successful nonsurgical management of a 21-year-old patient with cyclosporin A-induced gingival overgrowth who experienced a total regression of the gingival enlargement without any surgical procedure or drug substitution. And it highlights therefore the key role of supportive periodontal therapy in maintaining good and stable outcomes over 2 years of follow-up.

Abstract
Drug use for both therapeutic and recreational purposes is very widespread in most societies. The range of drugs used, the variations in response to these drugs and other health and behavioral confounders mean that drug use may be an important contributor to individualized periodontal diagnoses. In this narrative review, we review the main reported effects of drugs on the periodontal tissues and periodontal disease processes. Although some of the more common adverse drug reactions on periodontal tissues are well described, in many other cases the evidence for these drug effects is quite limited and based on small case series or isolated reports. Prescription drugs are responsible for a range of effects, including drug-induced gingival overgrowth and increased gingival bleeding, and influence periodontal inflammation and periodontal breakdown. The effects of recreational drugs on the periodontal tissues is less well researched, perhaps for the obvious reason that assembling large cohorts of recreational drug users presents particular challenges. Use of nearly all of these substances is associated with poorer periodontal and dental health, although there is almost certainly a large degree of behavioral confounding in these findings. Overall, further studies of adverse drug reactions on the periodontal tissues are required as this continues to be an important and increasing factor in periodontal health determination.

Abstract
BACKGROUND To analyze the role of proinflammatory cytokines in drug-induced gingival enlargement in Indian population. AIM To evaluate for the presence of interleukin-6 (IL-6) in drug-induced gingival enlargement and to compare it with healthy control in the absence of enlargement. MATERIALS AND METHODS Thirty-five patients selected for the study and divided into control group (10) and study group (25) consisting of phenytoin (10); cyclosporin (10) and nifedipine (5) induced gingival enlargement. Gingival overgrowth index of Seymour was used to assess overgrowth and allot groups. Under LA, incisional biopsy done, tissue sample fixed in 10% formalin and immunohistochemically evaluated for the presence of IL-6 using LAB-SA method, Labeled- Streptavidin-Biotin Method (LAB-SA kit from Zymed- 2(nd) generation LAB-SA detection system, Zymed Laboratories, CA). The results of immunohistochemistry were statistically analyzed using Kruskaal-Wallis and Mann-Whitney test. RESULTS The data obtained from immunohistochemistry assessment shows that drug-induced gingival overgrowth (DIGO) samples express more IL-6 than control group and cyclosporin expresses more IL-6 followed by phenytoin and nifedipine. CONCLUSION Increased IL-6 expression was noticed in all three DIGO groups in comparison with control group. Among the study group, cyclosporin expressed maximum IL-6 expression followed by phenytoin and nifedipine.

Abstract
BACKGROUND To assess changes in gingival status of renal transplant subjects under immunosuppressive regimens based on cyclosporine (CsA), tacrolimus (Tcr), and sirolimus (Sir). METHODS From a sample of 135 subjects (baseline examination [BE]), 89 without periodontal treatment, who maintained the immunosuppressive regimen based on the same main agent (CsA=23, Tcr=31, and Sir=35), were reexamined after 44 months (follow-up examination [FE]). Demographic, pharmacologic, and periodontal variables were collected and gingival overgrowth (GO) was assessed by visual examination. RESULTS In Tcr and CsA groups, although not significant, occurrence of GO decreased (CsA [BE=56.5% and FE=34.8%; P=0.063] and Tcr [BE=19.4% and FE=12.9%; P=0.500]). In addition, the severity of GO decreased significantly in CsA group (mean score BE=10.29 ± 7.70 and mean score FE=0.78 ± 1.38; P=0.003). In Sir group, GO decreased from 17.1% (BE) to 0.0% (FE) (P=not applicable). In total sample, GO was associated with papillary bleeding index (P=0.001) and concomitant use of calcium channel blockers (P=0.029); in CsA and Tcr groups, GO was associated with papillary bleeding index (P=0.029 and 0.033, respectively). CONCLUSIONS There was no incidence of GO, and a decrease in the occurrence and severity of GO was significant in total sample. This decrease can be attributed to changes in pharmacologic and periodontal variables over this period of time.

Abstract
BACKGROUND Variances in fibroblasts' α2β1 integrin intensity may lead to altered adhesion to type I collagen and consequently to suppression of phagocytosis which may be one of the mechanisms for drug induced gingival overgrowth. The present study aimed to evaluate the genotype and allele frequencies of α2 integrin +807 gene in renal transplant patients with and without gingival overgrowth. MATERIAL AND METHODS Seventy renal transplant patients with cyclosporine A (CsA)-induced gingival overgrowth (CsA GO+) were enrolled. Renal transplant patients without GO medicated with CsA (CsA GO-; n=79) and tacrolimus (Tac; n=52) served as controls. DNA was obtained from peripheral blood and ITGA2 +807C/T polymorphism was genotyped by polymerase chain reaction and restriction fragment length polymorphism method. Clinical parameters including probing depth and plaque, papilla bleeding and hyperplasia indexes were recorded. Chi-square, Kruskal-Wallis and Mann-Whitney tests were used in statistical analysis. RESULTS Clinical parameters of CsA GO+ group were significantly higher than those of the CsA GO- and Tac groups (p<0.05). ITGA2 807C/T genotype and allele frequencies of study groups were similar (p>0.05). CONCLUSION Within the limits of the present study it can be concluded that ITGA2 +807 gene polymorphism is not associated with susceptibility to CsA-induced GO.

Abstract
Gingival overgrowth/hyperplasia can be attributed to several causes, but drug-induced gingival overgrowth/hyperplasia arises secondarily to prolonged use of antihypertensive drugs, anticonvulsants and immunosuppressants. The management is complex in nature considering the multitude of factors involved such as substitution of drug strict plaque control along with excision of the tissue to be performed under local anesthesia as outpatient. In the recent times, the patient's psychological fear of the treatment with the use of surgical blade and multiple visits has developed the concept of single visit treatment under general anesthesia incorporating a laser as viable option. The present case highlights the new method of management of gingival overgrowth.

Abstract
BACKGROUND The aim of this study is to compare gingival changes induced by short- and long-term tacrolimus and nifedipine administration, alone or in combination, and evaluate the expression levels of tumor suppressor phosphatase and tensin homolog (PTEN) in drug-induced gingival overgrowth. METHODS Eighty rats were equally divided into eight groups: 1) tacrolimus for 8 weeks; 2) nifedipine for 8 weeks; 3) tacrolimus and nifedipine for 8 weeks; 4) 8-week control; 5) tacrolimus for 24 weeks; 6) nifedipine for 24 weeks; 7) tacrolimus and nifedipine for 24 weeks; and 8) 24-week control. Histomorphometric analyses included measurements of epithelial thickness, connective tissue thickness, and height. Stereologic analyses included measurements of volumetric densities of fibroblasts (Vf), collagen fibers (Vcf), and blood vessels (Vbv). In addition, PTEN expression was analyzed using immunohistochemistry. RESULTS Epithelial thickness and connective tissue thickness were significantly increased in groups 5, 6, and 7 compared to group 8 (P <0.05), whereas connective tissue height was significantly increased in groups 5 and 7 (P <0.001). Vf and Vcf were significantly increased in group 7 compared to group 8 (P <0.001). PTEN immunoreactivity was significantly decreased in all experimental groups compared to the control groups (P <0.05). CONCLUSIONS Results suggest that duration of drug administration is a more important risk factor than drug combination. The results include a potentially new insight about PTEN's role in the etiology of drug-induced gingival overgrowth.

Abstract
AIM To assess the prevalence and variables associated with gingival overgrowth (GO) in renal transplant recipients medicated with cyclosporine (CsA), tacrolimus (Tcr), or sirolimus (Sir). MATERIALS AND METHODS One hundred and thirty-five eligible subjects were divided in CsA, Tcr, and Sir groups comprising 45 subjects each. GO was visually assessed and subjects were assigned as GO+ or GO- in a post hoc definition. Saliva samples were collected and the presence of periodontal pathogens was assessed through polymerase chain reaction. Variables of interest were compared between GO+ and GO- subjects through univariate and multivariate analysis. RESULTS Prevalence of GO was of 60.0% for CsA, 28.9% for Tcr, and 15.6% for Sir groups. Within the CsA group, GO was associated with papillary bleeding index (p=0.001); within the Tcr group, GO was associated with CsA previous use (p=0.013), and calcium channel blockers (CCB) use (p=0.003); within the Sir group, GO was associated with papillary bleeding index (p=0.018), and CCB use (p=0.020). A higher frequency of Tannerella forsythia was observed among GO+ subjects medicated with Tcr. CONCLUSION Pharmacological and periodontal variables were associated with GO in different immunosuppressive regimens. Integration between the medical and the dental team may be an important approach in the post-transplant maintenance routine.

Abstract
Changes in the oral cavity, such as periodontitis and other manifestations of poor oral health, are common in patients with chronic kidney disease (CKD) and may contribute to increased morbidity and mortality because of systemic consequences such as inflammation, infections, protein-energy wasting, and atherosclerotic complications. Poor oral health in CKD patients may thus represent an important, but often overlooked, problem. Several studies show that uremic patients have higher rates of decayed, missing, and filled teeth, loss of attachment, and periapical and mucosal lesions than the general population. The consequences of poor oral health may be more severe in CKD patients because of advanced age, common comorbidities such as diabetes, concurrent medications, and a state of immune dysfunction that may increase the risk for systemic consequences of periodontitis and other oral and dental pathologic conditions. Poor dentition and other signs of poor oral health should be an alarm clock also at early stages of CKD. However, it remains to be determined whether more successful management of poor oral health and periodontitis will reduce the risk of inflammation, infection, protein-energy wasting, and atherosclerotic complications in CKD patients. This review explores etiological factors and potential systemic consequences of poor oral health in CKD patients as well as possible preventive and therapeutic strategies.

Abstract
BACKGROUND The aim of this study is to make a longitudinal evaluation of the incidence and severity of gingival overgrowth (GO) induced by immunosuppressive agents, such as tacrolimus (Tcr) and cyclosporin A (CsA), in the absence of calcium channel blockers in patients undergoing renal transplantation (RT). METHODS This longitudinal study is conducted in 49 patients with RT who were divided into a CsA group (n = 25) and Tcr group (n = 24). The individuals were assessed at four time intervals: before transplant and 30, 90, and 180 days after RTs. Demographic data and periodontal clinical parameters (plaque index, cemento-enamel junction to the gingival margin, probing depth, clinical attachment level, bleeding on probing [BOP], and GO) were collected at all time intervals. RESULTS The mean GO index was significantly lower in the Tcr group compared to the CsA group after 30 (P = 0.03), 90 (P = 0.004), and 180 (P = 0.01) days of immunosuppressive therapy. One hundred eighty days after RTs, a clinically significant GO was observed in 20.0% of individuals in the CsA group and 8.3% of individuals in the Tcr group. However, this difference was not statistically significant (P = 0.41). There was a reduction in periodontal clinical parameters regarding the time of immunosuppressive therapy for PI and BOP (P <0.001) in both groups. CONCLUSION Although there was no statistical difference in the incidences of clinically significant GO after 180 days of immunosuppressive therapy, it was observed that GO occurred later in the Tcr group, and the severity of GO in this group was lower than in patients who used CsA.

Abstract
AIM The rationale of this study was to address whether local or systemic changes reflect proteolytic (matrix metalloproteinase-13) or oxidative (myeloperoxidase) stress in renal transplant patients receiving cyclosporine-A (CsA) and having gingival overgrowth (GO), in patients receiving CsA therapy and having no GO and patients receiving tacrolimus therapy. MATERIAL AND METHODS Gingival crevicular fluid (GCF) samples were collected from sites with (GO+) and without GO (GO-) in CsA patients having GO; GO- sites in CsA patients having no GO; sites from tacrolimus, gingivitis and healthy subjects. GCF and serum myeloperoxidase (MPO) and matrix metalloproteinase-13 (MMP-13) levels were determined by ELISA. RESULTS GO+ sites in CsA patients having GO had elevated GCF MPO levels than those of CsA patients having no GO, tacrolimus and healthy subjects (p<0.005), but comparable to those of gingivitis. GCF MPO levels were higher in GO+ compared to GO- sites in CsA patients having GO (p<0.05). Patient groups had similar, but higher GCF MMP-13 levels than healthy group. CONCLUSIONS These results show that CsA and tacrolimus therapy have not a significant effect on GCF MPO and MMP-13 levels, and gingival inflammation seems to be the main reason for their elevations.

Abstract
Hereditary gingival fibromatosis (HGF) is a rare, clinically variable disorder characterized by slowly progressive fibrous overgrowth of the gingiva. Four gene loci have been mapped for autosomal dominant non-syndromic HGF (adHGF). The molecular basis of adHGF remains largely unknown, with only a single SOS1 gene mutation identified so far at the gingival fibromatosis 1 (GINGF1) locus in one family. We identified an adHGF family with ten affected individuals in whom onset of gingival fibromatosis concurred with the eruption of the primary teeth. In order to identify the molecular basis in this family, we tested for linkage of the disease to known adHGF loci. A maximal multipoint logarithm of the odds score of 3.91 was obtained with marker D2S390 (theta = 0) at the GINGF3 locus on chromosome 2p23.3-p22.3, and linkage to other known loci was excluded. Sequencing two candidate genes, ALK and C2orf18, and a single nucleotide polymorphisms array analysis did not reveal a mutation or copy number variation in a patient from the family. We refined the GINGF3 locus to a 6.56-cM, 8.27-Mb region containing 112 known and hypothetical genes, and our data and a search of the literature suggest that GINGF3 is a major adHGF locus.

Abstract
OBJECTIVES We conducted a study among pediatric renal (RTRs) and liver transplant recipients (LTRs) to determine: a) the overall burden of oral disease; and b) the frequency with which this population utilizes dental care services in relation to sociodemographic factors and oral disease burden. METHODS In this cross-sectional survey, study procedures included the completion of a standardized questionnaire (by parents/guardians), oral mucosal examination, assessment of caries, gingival enlargement, and plaque index. RESULTS The 142 children (82 RTRs and 60 LTRs) enrolled from April 2002 to November 2005 were predominantly Latino (41 percent) and Caucasian (34 percent). Forty-three percent had at least one carious surface (in either a deciduous or permanent tooth), 19 percent had five or more carious surfaces, and 25 percent had gingival enlargement. We found only one case of oral candidiasis. Even though 72 percent of parents/guardians reported their child had a regular source of dental care, only 49 percent had a dental cleaning and 44 percent had dental radiographs in the past year, reflecting a low prevalence of preventive dental care. Among children with no regular source of dental care, there were statistically significantly higher proportions of Latinos, younger children, and families with an annual household income <$35,000. CONCLUSION While the prevalence of oral mucosal disease and gingival enlargement was low, the prevalence of children with caries was high, and there was low use of preventive dental care. Strategies to improve this population's utilization of preventive dental care are needed.

Abstract
BACKGROUND Although the prevalence of gingival overgrowth (GO) in calcineurin-inhibitor (CNI) immunosuppressive regimens has been well documented, to the best of our knowledge data from sirolimus (SIR) regimens have not been described. We sought to investigate the gingival status of renal transplant recipients under SIR-based regimens with regard to the prevalence and potential risk variables associated with GO. METHODS A cross-sectional study was conducted at a public hospital in Belo Horizonte, MG, Brazil. Of 886 transplant recipients, an eligible sample of 144 subjects was selected. Medical, pharmacologic, and periodontal variables were recorded for each subject. GO was assessed through visual inspection and was evaluated in relation to variables of interest by univariate and multivariate analyses. RESULTS Although not clinically significant, 20.8% of the samples had GO, with a mean GO score of 5.0% +/- 3.98% (range, 0% to 19%) and mean GO score per papilla of 0.378 +/- 0.361 (range, 0.1 to 1.9); the percentage of papilla affected by GO was 14.35% +/- 9.86% (range, 5% to 45%). The multivariate final model, excluding periodontal variables, showed that the concomitant use of calcium channel blockers (P = 0.033) and the interaction between time since transplant and previous CNI use (P <0.001) were associated with GO. Adding periodontal variables to the model improved its accuracy and retained papillary bleeding index as being strongly associated with GO (P <0.001). CONCLUSIONS GO was observed in a considerable number of subjects under SIR-based immunosuppressive regimens, although the relationship was not clinically significant. Findings point to the importance of cooperation between medical and dental health care personnel in the maintenance of renal transplant recipients under SIR-based immunosuppressive regimens.

Abstract
Gingival overgrowth (GO) is the main oral manifestation in transplant recipients who use calcineurin inhibitors. In the present study, factors for GO development were investigated in Brazilian renal transplant recipients who were prescribed cyclosporine (CsA) or tacrolimus (TAC). Demographic, pharmacological, clinical, and periodontal data were obtained from 83 patients, as well as HLA expression in 51 of them. The prevalence of GO was high (47%), but its severity was low according to periodontal indices. The prevalence of GO was greater among patients who used CsA (n = 49) than those receiving used TAC (n = 34) namely, 61% versus 26.5% (P = .003). Comparisons between patients with versus without GO were performed independent of the administered immunossupressant. The group with GO showed a greater degree of gingival inflammation index. HLA-A68 had greater expression among patients without GO (P = .04). The risk factors for GO occurrence were evaluated using a multivariate analysis that identified gingival inflammation and HLA-A24 expression as risk factors. Increased age and use of TAC were identified as protective factors. GO showed a high prevalence, yet a light intensity. Patients who were younger, men, or received CsA showed a greater occurrence of GO. The risk factors identified for GO development were the presence of gingival inflammation and HLA-A24 expression.

Abstract
BACKGROUND Tacrolimus is a new-generation immunosuppressant as successful as cyclosporin in suppressing organ transplant rejection. Although cyclosporin is known to cause gingival enlargement (GE), tacrolimus has not been associated with this condition. We sought to explore the prevalence of GE among renal transplant recipients (RTRs) in relation to cyclosporin and tacrolimus while controlling for the effect of calcium channel blockers (CCBs) and supragingival plaque. METHODS RTRs were recruited from our institution's Kidney Transplant Unit. Participants completed a standardized questionnaire and received a complete oral examination, including a soft tissue examination and a periodontal examination measuring probing depth, recession, bleeding on probing, plaque index (PI), and GE. RESULTS Among 115 RTRs, 39 (34%) presented with GE, with the highest prevalence among those taking cyclosporin and CCBs (76%) and the lowest among tacrolimus users not on a CCB (15%). Tacrolimus was not found to be associated with GE. Cyclosporin was found to be associated with GE in a univariate analysis stratified by the use of CCBs, but multivariate analysis revealed that the only significant risk factors for GE were the use of CCBs and the widespread presence of abundant supragingival plaque (PI > or =2 on >40% of tooth surfaces). CONCLUSIONS This study confirmed that tacrolimus is not associated with GE. Cyclosporin taken at the currently recommended low dosage and not in combination with a CCB may not be associated with a significant risk for GE in individuals with good oral hygiene. CCBs should be avoided among patients taking cyclosporin and those with poor oral hygiene.

Abstract
The incidence of end-stage renal disease (ESRD) is increasing and patients receiving renal replacement therapy including hemodialysis, peritoneal dialysis or renal transplantation will comprise an enlarging segment of the dental patient population. Renal replacement therapy can affect periodontal tissues including gingival hyperplasia in immune suppressed renal transplantation patients and increased levels of plaque, calculus and gingival inflammation and possible increased prevalence and severity of destructive periodontal diseases in ESRD patients on dialysis maintenance therapy. Also, the presence of undiagnosed periodontitis may have significant effects on the medical management of the ESRD patient. Periodontitis has been found to contribute to systemic inflammatory burden including the elevation of C-reactive protein (CRP) in the general population. Atherosclerotic complications including myocardial infarction and stroke are the primary causes of mortality in the ESRD population and, in contrast to that of the general population, the best predictor of all cause and cardiac death in this population is CRP. Consequently, periodontitis may be a covert but treatable source of systemic inflammation in the ESRD population. The objective of this review was to explore the interaction between chronic renal disease, renal replacement therapy and periodontal diseases based upon the results of studies published within the last decade.

Abstract
AIM We investigated gingival crevicular fluid (GCF) and serum matrix metalloproteinase-8 (MMP-8) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) levels from renal transplant patients receiving cyclosporine-A (CsA) and having gingival overgrowth (GO), from patients receiving CsA therapy and having no GO and patients receiving tacrolimus therapy. MATERIAL AND METHODS GCF samples were collected from sites with GO (GO+) and without GO (GO-) in CsA patients having GO; and GO- sites in CsA patients having no GO; sites from tacrolimus, gingivitis and healthy subjects. GCF and serum MMP-8 and TIMP-1 levels were determined by a time-resolved immunofluorometric assay (IFMA) and enzyme-linked immunosorbent assay. RESULTS GO+ sites in CsA patients having GO had elevated GCF MMP-8 levels compared with those of CsA patients having no GO, tacrolimus and healthy subjects (p<0.005), but these levels were similar to those of gingivitis. The GCF MMP-8 level was higher in GO+ compared with GO- sites in CsA patients having GO (p<0.05). GCF TIMP-1 levels were similar between groups. Tacrolimus patients had lower GCF MMP-8 levels than gingivitis (p<0.005), but levels similar to the healthy group. CONCLUSION These results show that CsA and tacrolimus therapy has no significant effect on GCF MMP-8 levels, and gingival inflammation seems to be the main reason for their elevations.

Abstract
BACKGROUND Gingival crevicular fluid (GCF) levels of transforming growth factor-beta(1) (TGF-beta(1)) have been previously investigated in relation to the pathogenesis of cyclosporine-A (CsA)-induced gingival overgrowth (GO) but no clinical data are available regarding the GCF levels of TGF-beta(1) in patients treated with tacrolimus (Tac). However, as gingival inflammation is pronounced at sites of GO and this consequently may lead to an elevation in TGF-beta(1) levels the present study aimed to evaluate gingival crevicular fluid (GCF) TGF-beta(1) levels in renal transplant patients using CsA or Tac without GO. METHODS GCF TGF-beta(1) levels were investigated in 30 renal transplant patients without GO medicated with either CsA (n=15) or Tac (n=15). Sixteen gingivitis patients and 15 periodontally healthy subjects were selected as controls. Periodontal status was evaluated by measuring probing depth, plaque index and papilla bleeding index. The TGF-beta(1) levels were analysed by enzyme-linked immunosorbent assay. RESULTS Both CsA and Tac groups had significantly elevated GCF TGF-beta(1) total amount compared to gingivitis and healthy groups (p<0.008). GCF TGF-beta(1) total amount of CsA and Tac groups was similar (p>0.008). Gingivitis and healthy groups had also similar GCF TGF-beta(1) total amount (p>0.008). CONCLUSIONS Within the limits of the present data it is unlikely that TGF-beta(1) is an exclusive mediator of CsA- or Tac-induced GO. However, pathogenesis of GO is multifactorial and contribution of TGF-beta(1) to the interrelations between cytokines and growth factors with fibrogenic potential cannot be disregarded.

Abstract
Calcineurin inhibitors (cyclosporine and tacrolimus) have been used as the mainstay immunosuppressive therapy for solid organ and hematopoietic cell transplantations (HCT) to prevent allograft rejection and for prophylaxis and treatment of the chronic graft-versus-host disease. Adverse effects of these drugs include nephrotoxicity, hepatotoxicity, neurotoxicity, hypertension and gingival hyperplasia. Association of oral non-gingival soft tissue hyperplasia with calcineurin inhibitor therapy has only recently been recognized and is thought to occur infrequently. We present four cases of oral non-gingival inflammatory fibro-vascular hyperplasias attributed to the use of calcineurin inhibitors following solid organ transplantation and HCT. These lesions interfere with function and must be differentiated from other oral lesions, and therefore should be surgically excised.

Abstract
AIM The aim of this study was to determine the incidence and severity of gingival overgrowth (GO) induced by tacrolimus (Tcr) compared with ciclosporin A (CiA) in the absence of calcium channel blockers (CCB) in renal transplant recipients. METHODS Forty patients (20 Tcr and 20 CiA) were evaluated before and 30 and 90 days after kidney transplantation. Demographic (age, gender) and periodontal parameters were recorded for all patients. Patients taking CCB at any time during the study were excluded from the investigation. RESULTS The mean GO score was significantly lower (p=0.014) in the Tcr group (6.4%) compared with the CiA group (17.9%) after 90 days of immunosuppressive therapy. At 90 days post-transplant, clinically significant GO was observed in four patients of the CiA group and in two of the Tcr group. This difference was not statistically significant (0.66). CONCLUSION No significant difference in the incidence of clinically significant GO was observed between the CiA and Tcr groups up to 90 days of immunosuppressive therapy.

Abstract
BACKGROUND/AIM The use of calcium channel blockers, especially nifedipine, causes gingival hyperplasia which leads to the destruction of the deeper periodontal tissues. During this process, inflammatory changes and the changes of colagen fibers occur. The aim of this study was to metrically compare the extent of proliferation of connective tissue in the deeper periodontal tissue in experimental animals regarding the dose and duration of nifedipine administration. METHODS The study involved 50 Wistar rats to which water solution of nifedipine was given in certain time intervals and doses. Before starting the experiment, i.e. before nifedipine administration, and in the defined time intervals, measuring of the morphology of gingival size was performed including the buccolingual and mesiodistal wideness and vertical altitude of the central interdental papilla. The measurement was performed by the use of a special graduated probe. Histometric analyses of the tissue samples were done on the sagital cross-sections in the direction from the top to the bottom of papilla on five levels. For the statistical analysis of the data, the established values to the extent of the most present changes were used. The mesiodistal and buccolingual diameters for the levels L2 and L3 were quantitively determined and compared. These values were compared to the vertical diameter of gingival growth determined before the onset of patohistologic analyses of the tissue samples. RESULTS At the begining of the experiment, the volume of the lower incisive central papilla in the rats was 12 mm(3). The central interdental papilla vertical altitude was 6.6 mm in rats which had received a lower dose of nifedipine, 8 mm in rats which had received a higher dose in the defined time intervals while the value for the control group was 3.8 mm. CONCLUSION The obtained results showed that the administration of nifedipine led to the extensive gingival hyperplasia in the experimental animals. Gingival hyperplasia correlates with both the dose of nifedipine and the duration of its administration.

Abstract
BACKGROUND The role of cyclosporin in the absence of calcium channel blockers and the associated risk variables of development and severity of gingival overgrowth have not yet been properly established. The present study was conducted to determine the effect of potential risk variables for gingival overgrowth severity in Brazilian renal transplant subjects medicated with cyclosporin in the absence of any calcium channel blockers. METHODS A cross-sectional study was conducted in a public hospital in Belo Horizonte, Brazil. Demographic, pharmacologic, and periodontal data, recorded from 194 subjects taking cyclosporin in the absence of calcium channel blockers, were analyzed using independent sample t, chi2 statistic, or Mann-Whitney U tests. The effects of potential risk variables of gingival overgrowth severity were determined using backward stepwise regression analysis. RESULTS The prevalence of clinically significant gingival overgrowth was 34.5% (N = 67). These subjects presented a significantly higher papillary bleeding index and a higher plaque index compared to those without clinically significant gingival overgrowth. When all demographic, pharmacologic, and periodontal data were evaluated in relation to gingival overgrowth severity, time since transplant, papillary bleeding index, serum cyclosporin concentration, and prednisolone and azathioprine dosages were significant in the univariate modeling (P <0.05) and remained significant when evaluated in the multivariate modeling (P <0.0001; adjusted R2 = 39.4%). CONCLUSIONS In the absence of calcium channel blockers, this study showed that pharmacologic variables, such as cyclosporin serum concentration, prednisolone and azathioprine dosages, and time since transplant, are strongly related to gingival overgrowth. In addition, the periodontal variable papillary bleeding index highlighted the primary role of inflammation on the pathogenesis and severity of gingival overgrowth.

Abstract
OBJECTIVES This review critically evaluates the different therapies that are available to manage drug-induced overgrowth (DIGO). MATERIAL AND METHODS This review is based on literature identified using the online databases MEDLINE and PUB MED. It is not a systematic review, but a conventional review of the relevant literature. RESULTS Patients benefit from a non-surgical approach if this can be delivered before commencement of medication although in many instances this may not be practicable. Systemic antibiotic usage has been evaluated in the management of ciclosporin-induced gingival overgrowth. Efficacy appears to be equivocal and long-term use is undesirable. Surgical excision remains the main treatment option especially for patients with severe overgrowth. Few studies have compared different techniques with respect to recurrence rate or post-operative sequelae. CONCLUSION DIGO is a common clinical problem that often requires intervention. Non-surgical techniques can limit the occurrence of this unwanted affect, reduce the extent of plaque-induced gingival inflammation and reduce the rate of recurrence. Wherever possible this management strategy should be adopted first. Surgical treatment is often the most reliable option and scalpel gingivectomy remains the treatment of choice. Further investigations are required to develop appropriate management strategies to prevent recurrence of DIGO.

Abstract
BACKGROUND Some reports suggest that the prevalence and severity of gingival overgrowth (GO) is lower in patients taking tacrolimus (Tcr) than in those taking cyclosporin A (CsA). The present study was conducted to determine the prevalence and severity of GO in a group of renal transplant recipients treated with Tcr in comparison to those treated with CsA and to evaluate the risk variables associated with the development of GO in these two drug regimens. METHODS A cross-sectional study was conducted in a public hospital in Belo Horizonte City, Brazil. Demographic, pharmacological, and periodontal data were recorded for each subject. Variables from 134 subjects taking Tcr were compared to 451 subjects taking CsA using independent sample t, chi(2) statistic, or Mann-Whitney tests. The effects of potential risk factors on GO severity were determined using forward and backward stepwise regression analysis. RESULTS Subjects taking CsA showed a higher mean GO score (29.03% +/- 22.9%) compared to subjects taking Tcr (16.9% +/- 3.4%) (P = 0.0038). In the Tcr group, 17.9% of the subjects had clinically significant GO compared to 38.1% in the CsA group (P = 0.045). In the multivariate final model, papillary bleeding index, azathioprine dosage, and concomitant use of calcium channel blockers (CCB) were significant variables associated with severity of GO in Tcr and CsA groups. In addition, previous CsA use also remained significant for GO in subjects under a Tcr regimen. CONCLUSIONS The prevalence and severity of GO is lower in transplant subjects taking Tcr compared to CsA. GO severity in both groups was strongly associated with the papillary bleeding index, highlighting the role of inflammation in this condition. Concomitant CCB use, azathioprine dosage, and previous CsA use in the Tcr group reinforces the possible synergistic effects of these pharmacological variables on GO severity.

Abstract
OBJECTIVE The aim of this study was to determine the oral status of renal transplant recipients receiving cyclosporin A (CsA) or tacrolimus (FK-506) as immunosuppressant. SUBJECTS AND METHODS A total of 88 renal transplant recipients receiving CsA (63 men and 25 women, mean age 51.4 years) and 67 receiving FK-506 (57 men and 10 women, mean age 33.5 years) were included in the study. Donor type, histocompatibility, cold ischemia time and prior delayed graft function were similar between the two groups. Demographics and pharmacological data were recorded for all subjects. RESULTS The results demonstrated that CsA caused a greater number of oral diseases. A greater number of gingival overgrowth was present in patients treated with CsA. However, the combined use with calcium channel blockers increased the gingival overgrowth number. The occurrence of candida in saliva was observed in 80 renal recipients treated with CsA and 20 treated with FK-506. The presence of squamous oral carcinoma (n = 3) and herpes simplex (n = 10) was observed in patients treated with CsA. These alterations were not observed in renal recipients treated with FK-506. CONCLUSIONS Renal recipients constitute a high-risk group for oral diseases, as they are immunocompromised. However, the FK-506 regime appears to ameliorate this effect, compared with CsA. Adequate pre- and post-transplant oral health care is recommended for these subjects, irrespective of the time interval for which the drug is administered.

Abstract
BACKGROUND The aim of this study was to compare the morphologic changes in the gingiva brought about by the administration of cyclosporin and tacrolimus in rats. METHODS The study was conducted on 30 six-week-old male Sprague-Dawley rats, divided into three groups of 10 rats each, for a period of 4 weeks. Group I rats received cyclosporin (30 mg/kg body weight), and group II rats received tacrolimus (1.5 mg/kg body weight), by means of a gavage. Group III served as control and received olive oil alone. Impressions of the mandibular incisal region were made weekly, and stone casts were prepared for measuring morphologic changes of the gingiva. RESULTS An increase in the measured gingival dimensions was observed in the test groups as early as week 2 after the commencement of drug administration. Intergroup comparison revealed that the increase in the measured dimensions was greater in group I than group II at the end of 4 weeks. CONCLUSIONS Cyclosporin and tacrolimus were capable of causing gingival enlargement in Sprague-Dawley rats. However, the magnitude of tacrolimus-influenced gingival enlargement seemed to be comparatively less than cyclosporin.

Abstract
Cyclosporin is a potent immunosuppressant drug commonly used to prevent organ transplant rejection. In recent years, there has been a widening of its therapeutic use and an increase in the number of patients undergoing transplantation. Gingival overgrowth is one of several oral side-effects of cyclosporin, with a quoted prevalence of between 8% and 100%. There is continued debate over the factors which modify the degree of overgrowth, including individual sensitivity, age, dose of drug, duration of drug therapy and the presence of dental plaque. The exact mechanism of gingival overgrowth is still being debated, but appears to be caused by a combination of the proliferation of fibroblasts within the gingival tissue, an increase in the deposition of collagen and extracellular matrix, and a decrease in phagocytosis with a net gain in gingival tissue mass. A number of treatment options are utilized in the treatment of gingival overgrowth, including CO2 laser surgery, improved oral hygiene, the use of antibiotics such as metronidazole and azithromycin, and surgical intervention. In the clinical application of cyclosporin, there is little correlation between cyclosporin dose, serum trough levels and total exposure to the drug, making it difficult to achieve the desired therapeutic response. These problems were previously further complicated by the variability of absorption of the drug via the gastrointestinal tract. The original cyclosporin formulation, Sandimmune, was replaced by a new formulation, Neoral, which has a more reliable absorption, and gives a closer correlation between trough concentration levels and individual bioavailability. There is a conflict of opinion over whether or not the side-effect profile of Neoral varies from its precursor Sandimmune. It has yet to be seen whether the increased bioavailability of Neoral will result in an increased severity and prevalence of gingival overgrowth. An alternative immunosuppressant drug, tacrolimus, which is a macrolide antibiotic with a different side-effect profile, has emerged as a substitute for cyclosporin in organ transplantation. However, there have been conflicting reports of its side-effects and its capacity to cause gingival overgrowth.

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.
