Periodontitis Impact in Interleukin-6 Serum Levels in Solid Organ Transplanted Patients: A Systematic Review and Meta-Analysis. Diagnostics (Basel) 2020; 10:diagnostics10040184. [PMID: 32230707 PMCID: PMC7235754 DOI: 10.3390/diagnostics10040184] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 03/17/2020] [Accepted: 03/25/2020] [Indexed: 12/11/2022] Open
Abstract
This systematic review aimed to investigate the influence of periodontitis on post-transplant IL-6 serum levels of solid organ transplanted patients as compared to healthy subjects. Four databases (PubMed, Scholar, EMBASE, and CENTRAL) were searched up to February 2020 (PROSPERO CRD42018107817). Case-control and cohort studies on the association of IL-6 serum levels with a periodontal status of patients after solid organ transplantation were included. The risk of bias of observational studies was assessed through the Newcastle-Ottawa Scale (NOS). Random effects meta-analyses were thoroughly conducted. GRADE assessment provided quality evidence. Four case-control studies fulfilled the inclusion criteria (274 transplant recipients and 146 healthy controls), all of low risk of bias. Meta-analyses revealed significantly higher IL-6 levels in transplanted patients than healthy individuals with low-quality evidence (Mean Difference (MD): 2.55 (95% confidence interval (CI): 2.07, 3.03)). Transplanted patients with periodontitis have higher serum IL-6 levels than transplanted patients without periodontitis with moderate quality evidence (MD: 2.20 (95% CI: 1.00, 3.39)). We found low-quality evidence of higher IL-6 levels than healthy patients in patients with heart and kidney transplant. In these transplanted patients, there was moderate quality evidence that periodontitis is associated with higher IL-6 serum levels. Future research should consider the impact of such a difference in organ failure and systemic complications.

Abstract
BACKGROUND Oral disease may be increased in people with chronic kidney disease (CKD) and, due to associations with inflammation and malnutrition, represents a potential modifiable risk factor for cardiovascular disease and mortality. We summarized the prevalence of oral disease in adults with CKD and explored any association between oral disease and mortality. METHODS We used systematic review of observational studies evaluating oral health in adults with CKD identified in MEDLINE (through September 2012) without language restriction. We summarized prevalence and associations with all-cause and cardiovascular mortality using random-effects meta-analysis. We explored for sources of heterogeneity between studies using meta-regression. RESULTS Eighty-eight studies in 125 populations comprising 11 340 adults were eligible. Edentulism affected one in five adults with CKD Stage 5D (dialysis) {20.6% [95% confidence interval (CI), 16.4-25.6]}. Periodontitis was more common in CKD Stage 5D [56.8% (CI, 39.3-72.8)] than less severe CKD [31.6% (CI, 19.0-47.6)], although data linking periodontitis with premature death were scant. One-quarter of patients with CKD Stage 5D reported never brushing their teeth [25.6% (CI, 10.2-51.1)] and a minority used dental floss [11.4% (CI, 6.2-19.8)]; oral pain was reported by one-sixth [18.7% (CI, 8.8-35.4)], while half of patients experienced a dry mouth [48.4% (CI, 37.5-59.5)]. Data for kidney transplant recipients and CKD Stages 1-5 were limited. CONCLUSIONS Oral disease is common in adults with CKD, potentially reflects low use of preventative dental services, and may be an important determinant of health in this clinical setting.

Abstract
Objective: An inter-relationship between periodontal disease and systemic health has been suspected for centuries, but evidence to explain the connection has only been elucidated in the past few decades. Among the systemic diseases, end stage renal disease has been shown to affect not only the general health of the patient but also oral and periodontal health. This study was undertaken to gain an insight into whether duration of dialysis therapy influences the oral and periodontal health of these patients and also to see if these parameters reflect their biochemical values. Materials and Methods: The study was conducted on 75 patients undergoing dialysis and a control group of 25 subjects. The study group was divided into three subgroups depending upon the duration of dialysis. Oral hygiene and periodontal disease status were measured by Simplified Oral Hygiene Index by Greene and Vermillion and Periodontal Disease Index by Ram-fjord. Biochemical parameters measured were blood urea nitrogen and salivary urea levels. Comparison of these parameters was made between the study and control groups through analysis of variance (ANOVA) and student's t-test. Results: Prevalence of periodontal disease was evident in the dialysis group. Oral hygiene status was poor in comparison with the control group. Clinical and biochemical parameters showed statistically significant difference between the groups rather than within the groups. Conclusion: Oral and periodontal health appeared to be compromised. Their deteriorating general health is anticipated to cause negligence towards oral health care. This population needs comprehensive oral and periodontal care right from the diagnosis of chronic renal failure. There exists a need for communication between nephrologists and oral health care professionals. Longitudinal studies warranted in this regard.

Abstract
OBJECTIVES Impaired homeostasis and fluid balance are important physiopathological alterations in patients with chronic renal failure which may adversely affect the fluid dynamics and health status of tissues and organs. There are insufficient data about this phenomenon in periodontal tissues. The aim of this study was to evaluate the fluid dynamics of gingiva in children with end stage renal failure (ESRF), correlating this entity with gingival health in the same patient group. DESIGN Fifteen paediatric ESRF patients undergoing peritoneal dialysis (test group) and 15 systemically healthy children (control group) who were without periodontitis participated in the study. Fluid dynamics of gingiva were assessed via the gingival crevicular fluid (GCF) volume and tissue osmotic pressure (GOP) levels in the groups. GCF volume was measured using a Periotron 8000, whereas GOP was measured using a digital osmometer. Silness and Löe Plaque index (PI) and, Löe and Silness gingival index (GI) scores were utilized to determine the gingival health status in the study population. RESULTS There were increases in the GCF volume and GOP of the test group compared to those of the control group (p<0.01). The PI and GI scores were higher in the test group than in the control group (p<0.01). Strong and positive correlations were found between GI and GCF volume, GI and GOP and, GCF volume and GOP in both groups (p<0.01). CONCLUSIONS Our findings suggest that the fluid dynamics of gingiva may alter in children with ESRF, and this phenomenon may consequently affect the gingival health of these patients.

Abstract
AIM To evaluate the association between C-reactive protein (CRP) levels and the periodontal status of hemodialysis (HD) patients. METHODS 41 HD patients on rHuEPO therapy were enrolled in the study. Hematologic and biochemical parameters and CRP levels were recorded. The plaque index, gingival index, probing pocket depth and periodontal disease index were used to identify periodontal disease. The patients were divided into 2 groups: group 1 (n = 21), high CRP, and group 2 (n = 20), normal CRP. RESULTS After periodontal therapy, while the mean CRP level and erythrocyte sedimentation rate declined from 30.46 to 10.36 (p = 0.001) and from 93.4 to 35.8 mg/l (p = 0.001), respectively, the hemoglobin level increased from 9.4 to 10.6 g/dl (p = 0.009) and hematocrit level from 28.2 to 32.0% (p = 0.008) in group 1. CONCLUSION Periodontitis is an important and occult source of chronic inflammation and increases the CRP levels in HD patients. Periodontitis can cause hyporesponsiveness to rHuEPO treatment and decrease the hemoglobin levels.

Abstract
OBJECTIVE The aim of this study was to compare the oral health status of chronic renal failure (CRF) patients on renal replacement therapy with a matched reference population. DESIGN Cross-sectional study. SUBJECTS Forty-two dentate CRF patients--aged 25-52 years old--were matched with a reference group of 808 dentate subjects. METHODS The oral health was assessed using decayed missing filled (DMF) indices, simplified oral hygiene index and periodontal status. An oral health questionnaire was used to assess self-reported dental problems. Student t-tests and chi-square tests were performed to compare the CRF patients with the controls. RESULTS All index-scores in the CRF patients were comparable with the controls except for number of teeth covered with calculus that was significantly higher (P < 0.05) in CRF patients (4.1 +/- 2.6) than in controls (3.0 +/- 2.9). The self-reported oral health questionnaire revealed a trend for increased temporomandibular complaints in CRF patients (16.7%vs 5.7% in controls; P = 0.06) as well as bad taste (31.0%vs 6.8% in controls, P = 0.08). CONCLUSIONS For most dental aspects, the oral health of CRF patients is comparable with controls.

Abstract
AIM/OBJECTIVE The aim of this study was to perform periodontal assessment, using the CPITN index, on patients undergoing renal dialysis. METHODS The periodontal conditions of 342 subjects undergoing renal dialysis from eight renal dialysis centres were examined using CPITN. Subjects were distributed into four age groups, 16-19, 20-34, 35-44 and > or =45 years. The study was conducted during a 6-month period. All clinical examinations were performed by one examiner. RESULTS There was a significant positive relationship between the CPITN scores and age (r=0.164, p=0.002) and dialysis duration (r = 0.240, p=0.000). There was no statistically significant difference between male and female patients (p>0.05). None of the age groups had healthy sextants. The 35-44 year-age group had a higher number of sextants with deep pockets (0.19) than the other age groups and edentulous sextants were the highest among the oldest age group (1.89). CONCLUSION A very small portion of the renal dialysis population is affected by severe forms of periodontitis requiring complex periodontal treatment. However, all such patients should be given oral hygiene education as a priority.

Abstract
UNLABELLED There is little information on the oral health of children undergoing renal transplantation during the early transplant period. METHODS Twenty-four children undergoing renal transplantation aged 4-13.2 years and their matched controls were recruited. The dmfs, dmft, DMFS and DMFT, plaque, gingivitis and gingival enlargement scores were recorded. The oral microflora was sampled and cultured for S. mutans, Lactobacllus species and Candida species. RESULTS There was a significantly lower mean dmfs (0.3 +/- 0.9; P = 0.03), dmft (0.3 +/- 0.9; P = 0.03), DMFS (2.3 +/- 5.3; P = 0.01) and DMFT (1.5 +/- 2.6; P = 0.02), respectively, in the transplant group. There was a significantly greater mean plaque score (14.7 +/- 11) for the permanent dentition, at baseline only, compared with 90 days post-transplantation (9.4 +/- 10.4; P = 0.02). There was a significantly greater gingival enlargement score (1.8 +/- 1.4; P = 0.04) 90 days post-transplantation compared with baseline. The S. mutans and Lactobacillus counts were significantly lower both at baseline (P = 0.0001 and P = 0.004) and 90 days post-transplantation (P = 0.02; and P = 0.05), respectively, compared with the controls. CONCLUSIONS The transplant children had less active dental disease than the controls although gingival enlargement needs careful monitoring.

Abstract
BACKGROUND Chronic destructive periodontal disease is characterized by gingival inflammation, periodontal pocket formation, and bacterial plaque that lead to alveolar bone destruction. Polymorphonuclear neutrophil leukocytes (PMNs) are the first line of defense against infection caused by dental plaque bacteria. Renal patients present functional abnormalities of PMN, including impaired chemotaxis, phagocytosis, and intracellular killing of bacteria. In view of the above, the aim of this work was to evaluate the effect of renal failure on bone damaged by periodontal disease using histomorphometric and histochemical parameters. METHODS Twenty male Wistar rats weighing 250 g were assigned to one of the following four groups: 1) control (no treatment); 2) renal failure (RF); 3) periodontal disease (PD); and 4) renal failure plus periodontal disease (RF+PD). All the animals were sacrificed 31 days after the onset of the experiment. Mesio-distally oriented sections of the first lower molar were obtained for histomorphometric and histochemical evaluation. RESULTS Total erosion, active erosion, and total number of tartrate-resistant acid phosphatase-positive (TRAP+) osteoclasts were found to be increased in the RF+PD group compared with the PD group. CONCLUSION Our results demonstrate increased bone resorption in animals with untreated renal failure and periodontal disease, and thus indicate that the release of different factors by inflammatory cells is magnified, accelerating the progression of the disease in this animal model.

Abstract
This study compared the clinical and microbiological status of periodontally diseased sites in 42 patients who had a renal transplant and were undergoing immunosuppressive therapy (21 taking azathioprin and corticosteroids [Az-C] and 21 taking cyclosporin-A [Cy-A] with those of 21 systemically healthy matched controls. Probing pocket depth (PPD), bleeding on probing (BOP) and gingival hyperplasia (GH) were measured at 339 sites. Subgingival plaque samples were analyzed for the presence of Porphyromonas gingivalis, Treponema denticola and/or Bacteroides forsythus using the BANA test. Our findings suggest that immunosuppressed patients showed significantly less inflammation and fewer putative anaerobic pathogens using the BANA test, and that patients undergoing therapy with cyclosporin-A have a higher frequency of sites with gingival hyperplasia when compared with patients medicated with azathioprin or corticosteroids.

Abstract
The primary purpose of this investigation was to determine the oral health status of individual's undergoing renal dialysis in southeastern Virginia. A sample was identified for this cross-sectional study via a local health maintenance organization. Three subgroups of the population were studied: 1) those who have been on renal dialysis for less than a year; 2) those on renal dialysis for 1 to 3 years; and 3) those on renal dialysis for longer than 3 years. Three dental indices the Periodontal Disease Index; the Decayed, Missing. Filled index; and the Simplified Oral Hygiene Index--were used to identify periodontal disease, dental caries activity, and oral hygiene status. Data were compiled and analyzed by using the parametric test, 1-way analysis of variance. Results suggested that 100% (n = 45) of the individuals undergoing renal dialysis presented with some form of periodontal disease (X = 3.15, SD = 1.41). The majority (64%) of the sample displayed either severe gingivitis (28%) or early periodontitis (36%). Sixty-four percent of the sample displayed a high DMF index (X = 11.77, SD = 7.55), while 98% of the sample accumulated calculus. Oral debris was present in 100% of the sample, resulting in a high Simplified Oral Hygiene Index score (X = 3.24, SD = 1.26), suggesting an increased need for oral care instruction. Findings led to the conclusion that the renal dialysis population in southeastern Virginia, regardless of length of time on dialysis, is in need of comprehensive professional oral care and self-care instruction. Oral disease was present and is a source of active infection in these medically compromised individuals and, as such, has dire implication for morbidity and mortality.

Abstract
Chronic renal disease is associated with well-documented impairments in polymorphonuclear leucocyte (PMN) function. PMNs are important in defending the periodontium against plaque infections. This report discusses a case of periodontitis in a patient with chronic renal failure. It presents treatment provided and 1-year follow up. It shows that periodontal infections in patients with depressed PMN function could still be managed successfully with standard periodontal treatment emphasizing plaque control.

Abstract
Porphyromonas gingivalis is an important oral pathogen with a strong association with adult periodontitis. Significant titers of specific IgG antibodies to P. gingivalis can be found in the sera of both gingivitis and periodontitis patients. Since IgG subclasses have different biological characteristics, the present study dealt with the serum IgG subclass response to outer membrane antigens of P. gingivalis. Western blot analysis of P. gingivalis outer membrane was carried out using 20 adult periodontitis and 20 age- and sex-matched gingivitis patients. Antibodies in sera of both adult periodontitis and gingivitis patients recognized 38 antigen bands, ranging in molecular mass from 11.1 to 161 kDa. IgG2 was the predominant antibody subclass response in both patient groups in terms of the numbers of outer membrane antigens recognized, followed by IgG3, IgG1, and IgG4. More antigens in all IgG subclasses except IgG4 were recognized in adult periodontitis cases. Of the 23 antigens identified by IgG2 antibodies, 9 were recognized predominantly in adult periodontitis and 3 in the gingivitis group. In the IgG1 subclass, 4 antigens were recognized predominantly in the adult periodontitis group while only 1 antigen was recognized significantly more in the gingivitis group. The IgG3 response identified 14 antigens ranging in molecular mass from 11.1 to 61.2 kDa in both groups. Ten antigens were recognized significantly by the adult periodontitis group. The lowest response was seen by IgG4 antibodies, with only 3 antigens of molecular mass 61.2, 52.3, and 38.8 kDa recognized, the latter two significantly in the adult periodontitis group.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This review considers the periodontal problems of renal transplant patients with particular reference to their drug therapy and the pretransplant uremia. It would appear that either disease- or drug-induced immunosuppression affords the renal transplant patient a degree of "protection" against periodontal breakdown. However, of more significance to the periodontologist is the problem of drug-induced gingival overgrowth with reference to both cyclosporin and nifedipine. Approximately 30% of dentate renal transplant patients medicated with cyclosporin alone experience significant gingival overgrowth which requires surgical excision. This figure increases to 40% when patients are medicated with both drugs. The pathogenesis of this unwanted effect is uncertain and the relationship between the expression of gingival overgrowth and various periodontal or pharmacokinetic variables remains a contentious issue. Clinical measures to prevent the occurrence of either cyclosporin- or nifedipine-induced gingival overgrowth are unsatisfactory.

Abstract
Periodontal diseases are thought to result from inflammatory responses to bacterial challenges in the gingival crevicular area. Antibodies are a major host-protective mechanism in many bacterial infections. Consequently, the antibody responses to suspected periodontal pathogenic bacteria have been extensively measured as to their relationship to diseases and specificity for suspected pathogens associated with progressing disease sites. Recently, studies on the bacterial immunogen characterization, antibody-subclass identification, and antibody biological capabilities have been reported. Although increased antibody levels to certain suspected periodontal pathogens were associated with periodontal diseases in humans, little evidence exists as to the role of these antibodies in the infectious process. In vivo experiments in animals indicated that specific antibodies against certain suspected periodontal pathogens were associated with suppression of bacterial colonization, limiting the spread of infection, and a decrease in alveolar bone loss. However, in vitro as well as in vivo experiments suggested that phagocytic cells are required for efficient bactericidal activity of antibodies and that the presence of other sensitized immune cells may either have inhibited or enhanced the infectivity of certain periodontal pathogens. Possible explanations for the observed inconsistencies are presented and the potential for utilization of specific anti-periodontal pathogen responses in the understanding and prevention of diseases is discussed.

The clinical and histological appearance of gingiva was evaluated in renal transplant recipients (RTR) receiving immunosuppressive drugs, in patients with chronic renal failure (CRF) undergoing hemodialysis, and systemically healthy individuals with periodontitis. Although the amount of bacterial plaque accumulation was similar among the groups (P greater than 0.05), the gingival inflammation was significantly less in RTR when compared to the other 2 groups (P less than 0.05). In light microscopic investigation the overall appearance of the connective tissue was similar in all of the groups. A mononuclear cell infiltration was present in all of the specimens; however, the number of inflammatory cells in patients with periodontitis was significantly higher than the other 2 groups (P less than 0.05). Prominent epithelial changes in the superficial layers of the oral epithelium; i.e., areas showing desquamation-like appearance, were noticed in patients with CRF. In electron microscopic investigation, fibroblasts and plasma cells with well-developed granular endoplasmic reticulum were found in connective tissue in RTR patients. In patients with CRF, epithelial cells presented swollen granular endoplasmic reticulum cisternae resembling vacuoles, indicating the presence of degeneration. It was suggested that with the use of immunosuppressive drugs the response to bacterial plaque did not diminish completely.

Abstract
The control of potentially periodontopathic microorganisms by host neutrophils is crucial to periodontal health. Neutrophils may use oxidative or nonoxidative mechanisms and either kill bacteria, influence bacterial growth, or modify bacterial colonization in the periodontium. Delivery of antimicrobial substances by neutrophils involves respiratory burst activity, phagocytosis, secretion, or cytolysis/apoptosis. Neutrophils contain a number of antimicrobial components including calprotectin complex, lysozyme, defensins, cofactor-binding proteins, neutral serine proteases, bactericidal/permeability increasing protein, myeloperoxidase, and a NADPH oxidase system. Many of these components are multifunctional and exhibit several mechanisms of antimicrobial activity. When comparisons are made among periodontal bacteria, differences in sensitivity to different components are observed. A hypothesis of specific defense is presented: That specific periodontal diseases can result from the failure of specific aspects of the host immune system (the neutrophil, in particular) in its interaction with specific periodontal pathogens. Failure may be due to phenotypic variation (pleomorphism) within the host or bacterial evasive strategies.

Abstract
The periodontium and periodontal disease activity can be affected by systemic drug therapy. Many drugs can have an adverse effect on the periodontium, i.e., gingival hyperplasia. Alternatively, some drugs can modify the inflammatory and immunological responses of the periodontal tissues to bacterial plaque. The aim of this review is to evaluate the effects of drug therapy on the periodontium and periodontal disease activity, and where possible, to relate such changes to the pharmacodynamics of the drugs considered. Drugs which have been reported to affect the periodontium can be categorised as follows: anti-epileptics, immunosuppressants, corticosteroids, non-steroidal anti-inflammatory drugs and hormones. Those drugs whose pharmacodynamics are clearly established and which affect the rate of periodontal disease activity, may provide information on the mechanisms of periodontal destruction. Finally, the mechanisms of drug-induced gingival hyperplasia (overgrowth) are discussed in relationship to the drugs' pharmacodynamics and pharmacokinetics.

Abstract
A case of cyclosporine-induced gingival overgrowth is presented. Overgrown and inflamed gingivae were noted at several sites in the mouth of a patient taking cyclosporine following a renal transplant. These were associated with areas adjacent to heavy plaque and calculus deposits on the teeth. Histological examination of the overgrown tissues revealed fibro-epithelial changes characterized by elongated rete pegs, myxomatous degeneration of the connective tissue associated with dense infiltration of plasma cells and lymphocytes. The fibroblasts from normal and overgrown sites were studied in vitro. Fibroblasts from the overgrown tissue proliferated at a slower rate and produced slightly less protein than the cells from normal, healthy gingival sites. These features reflect a site-specific alteration in fibroblast activity and indicate that the lesion is related to local factors exacerbated by cyclosporine therapy.

Abstract
Much of the connective tissue degradation that takes place in periodontal diseases is mediated by proteolytic enzymes. Previous studies have focused on the action of proteinases released by invading polymorphonuclear neutrophils and macrophages, and bacterial enzymes. In view of recent work establishing that resident connective tissue cells can be induced by cytokines to bring about the destruction of their own matrix, we propose a new hypothesis. In this we envisage that a critical step is the interaction of bacterial antigens with inflammatory cells, resulting in the production of a cytokine, interleukin-1. Our interpretation of in vitro evidence is that the loss of connective tissue attachment and bone matrix resorption in periodontal diseases is mediated by metalloproteinases such as collagenase and stromelysin released by cells of the periodontium. Such proteolytic destruction can be induced by interleukin-1, whose production may not be dependent on a specific microbial flora but may be triggered by a number of organisms. It is now clear that interleukin-1 has multiple actions on both immune and non-immune cells; these include the induction of lymphocyte differentiation and proliferation and the stimulation of bone and cartilage resorption, and prostaglandin and metalloproteinase synthesis by connective tissues. It seems likely that further knowledge about the production and function of this cytokine will have an increasing impact in many diseases that involve resorption, particularly since interleukin-1-like molecules can be produced by cell types other than monocytes/macrophages, including keratinocytes and fibroblasts.

Abstract
Several recent investigations indicate that some patients with adult periodontitis have lowered serum antibody levels or reduced lymphoproliferative responses to certain periodontitis-related microorganisms. Many such patients tend to show increased responses after therapy. Some suggested mechanisms of such responses are reviewed and the possible significance of immunosuppressive effects of periodontitis-related microorganisms are briefly discussed.

Abstract
In the present investigation, the frequency and severity of periodontal disease was assessed in a group of patients with multiple sclerosis receiving corticosteroid hormone therapy for neurological disease. Age-matched patients with multiple sclerosis but without hormone therapy as well as healthy subjects served as controls. Individuals suffering from multiple sclerosis or polyneuropathies were selected from a pool of patients who were under treatment at the Department of Neurology, The Central Hospital of Kuopio, Finland. 27 individuals were identified who had received more than 1.5 g prednisone over a 1-4 year period. The average amount of steroid given to these patients was 3.5 g. 26 individuals also suffering from neurologic disease had received no or only negligable amounts of hormone therapy and were used as diseased controls. Another control group comprised age- and sex-matched healthy individuals from the city of Kuopio. The dental examination which was performed by one dentist comprised assessments of the following parameters: oral hygiene status, gingival conditions, probing depth, gingival recession and height of the alveolar bone. The findings clearly demonstrated that patients with neurological disease who received corticosteroid therapy had the same frequency of gingivitis as non-treated diseased controls. Furthermore, data describing probing depth, gingival recession and height of the alveolar bone revealed that there was no difference regarding the frequency and severity of periodontal disease between the 2 groups of neurological diseased patients. It was concluded that corticosteroid therapy maintained over 1-4 years had no obvious influence on clinical parameters of periodontal disease in patients suffering from neurological disease.

Abstract
Great progress has been made in our understanding of the pathogenesis of periodontal disease, the primary role of bacteria as etiologic agents, and the critical modifying role of host responses. It is useful to consider several stages in the pathogenesis of periodontal disease - (a) colonization, (b) invasion, (c) destruction, and (d) healing - and to place into perspective the various host responses as they may affect each of these four stages (Table 5). With respect to colonization, although very little direct evidence is available, it is reasonable to suggest that antibodies, either secretory or serum-derived, acting by virtue of their ability to block attachment, could inhibit colonization by immune reduction of adherence mechanisms. With respect to invasion of the tissue, it appears that phagocytes, particularly the neutrophils, are important, acting in concert with opsonic antibody and complement in ingesting and killing the periodontal microflora before or during the early invasive process. A major advance in our understanding of the pathogenesis of periodontal diseases is the realization that the virulence of periodontopathic bacteria relates to their leukaggressive properties, allowing them to evade neutrophil protective mechanisms. Invasion of the periodontal tissues by bacterial products may be inhibited by the complexing of these products with antibody with the formation of antigen-antibody complexes that are phagocytosed and digested, particularly by scavenger phagocytes such as the macrophage. With respect to the destructive phase of periodontal disease, it is clear that the direct effect of lymphocytes mediated either through direct cytotoxic activity, or through biologically-active destructive lymphokines (such as alpha-lymphotoxin and osteoclast activating factor), can lead to tissue destruction. Macrophages, through the production of monokines, collagenase, and reactive oxygen species, can also lead to tissue destruction. The direct effects of bacterial toxins or enzymes which can lead to tissue destruction can be inhibited by complexing with antitoxic or enzyme-neutralizing antibodies. With respect to healing and fibrosis, very little direct information is available; however, it is possible that the lymphocytes and macrophages affect fibrosis by the production of chemotactic factors for fibroblasts which would be expected to bring them to the area of periodontal inflammation and also by production of fibroblast-activating factors, which then cause the fibroblasts to proliferate and produce collagen which replaces lost collagen or results in fibrosis.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The periodontal status of renal transplant patients on immunosuppressant drug therapy was compared with that of an age matched normal group over a period of 2 to 4 1/2 years. Gingival Index, Plaque Index, and Periodontal Destruction Index were used as measures of comparison. Over this period of time the Gingival Index of the immunosuppressed patients increased significantly when compared to the normals. There was a significant increase in the mean Plaque Index for both groups during the study period. The increase was greater in the immunosuppressed group. However, the difference in the Plaque Index for the two groups was not significant. There was little change in the Periodontal Destruction Index in both groups over time. The results of this study indicate that there is little difference in the rate of periodontal destruction between patients taking immunosuppressant drugs and normal patients. These findings, taken in conjunction with other recent reports, would seem to indicate that T cells play a minor role in the etiology of periodontal disease.

Abstract
The periodontal status of four kidney allograft patients was determined before and at periodic intervals for 9 months after receipt of the allografts. These patients received immunosuppressive drugs as part of their therapy, beginning at the time of transplantation. Three hemodialysis patients with analogous kidney disease and six eye patients who were otherwise healthy served as controls. Comparisons of plaque levels, pocket depths and gingival inflammation were made between the three groups of subjects. The results suggest that the administration of the immunosuppressive drugs significantly reduces the level of gingival inflammation in the presence of high levels of bacterial plaque. Pocket depths did not change significantly in eigher the allograft or control groups. Whole not conclusive, the findings support the hypothesis that host inflammatory and immunological responsiveness to plaque bacteria is a primary factor in the pathogenesis of destructive periodontal disease in humans.

Abstract
The periodontal status of a group of caries resistant and caries susceptible adult subjects was compared. Assessment was made of plaque accumulation, gingival inflammation and degree of periodontal destruction. When considered as a whole, there were no significant differences between the two groups. The female caries resistant subjects, however, exhibited a significantly lower gingival index, a lower level of periodontal destruction (borderline significance) but no difference in plaque index. The reason for the sex differences is not apparent. This study fails to support the view of an inverse relation between caries and periodontal disease.
