Evidence linking the association of periodontal viruses and pentraxins in periodontitis patients with coronary artery disease. J Periodontol 2024; 95:325-336. [PMID: 37483128 DOI: 10.1002/jper.23-0096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 06/24/2023] [Indexed: 07/25/2023]
Abstract
BACKGROUND Although there is ample evidence in the literature supporting a significant positive association between key periodontal pathogens and established inflammatory markers of periodontitis and coronary artery disease (CAD), their exact role remain unclear. Especially, the role of viruses in the etiology and specific biomarkers have not been validated. Thus, the current study aims to evaluate the role of periodontal viruses such as Epstein-Barr virus (EBV), cytomegalovirus (CMV), and herpes simplex virus (HSV), as well as the inflammatory marker pentraxin-3 (PTX3), and to analyze their association with CAD. METHODS The study included 240 patients divided into four groups of 60 patients each: nonperiodontitis + noncardiac (NP+NC) group, periodontitis + noncardiac patients (P+NC) group, nonperiodontitis + cardiac patients (NP+C) group, and periodontitis + cardiac (P+C) group. The cardiac surgery group (C-S) was a subgroup of NP+C and P+C. It consisted of 60 patients from the abovementioned two cardiac groups in whom coronary artery bypass graft (CABG) was indicated. Demographic variables, cardiac parameters, and periodontal parameters were recorded. The viruses (EBV, CMV, and HSV) and the inflammatory marker PTX3 were evaluated in the subgingival plaque samples of all the four groups and atheromatous plaque samples of the C-S using reverse transcriptase-polymerase chain reaction (RT-PCR) and quantitative polymerase chain reaction (qPCR), respectively, and were compared between the groups. The results were obtained and statistically analyzed. RESULTS The demographic variables did not differ significantly between the groups, except for age. Systolic blood pressure, diastolic blood pressure, low-density lipoprotein, and random blood sugar were significantly higher in NP+C and P+C, whereas high-density lipoprotein was significantly lower (p ≤ 0.05) in the same. Plaque index (PI), probing pocket depth (PPD), and clinical attachment level (CAL) were significantly higher (p ≤ 0.05) in P+NC and P+C. PTX were significantly elevated in P+C among the four groups. On evaluating the subgingival plaque samples, EBV and CMV were significantly higher in the two periodontitis groups P+NC and P+C (p = 0.000). HSV was significantly higher in the two cardiac groups (NP+C and P+C) (p ≤ 0.05). Cardiac EBV and CMV were significantly elevated in the P+C group with a p value of 0.004 and 0.033, respectively. Cardiac HSV was found in the NP+C group with statistical insignificance (p = 0.410) between the groups. On correlation, oral PTX were significantly associated with bleeding index (BI), PPD, and CAL (p = 0.000). Similarly, cardiac PTX showed significant association with PI, BI, PPD, and CAL (p = 0.000). Oral and cardiac PTX also showed significant correlation with each other. Multiple logistic regression analysis revealed a significant association between CAL and oral EBV (p ≤ 0.05). Similarly, cardiac EBV showed a significant association with CAL and oral EBV (p ≤ 0.05). Multiple logistic regression analysis also revealed that both cardiac and oral PTX showed a significant association only with oral EBV, CMV, and HSV. CONCLUSION The results of the current study suggest that the clinical severity of periodontitis (CAL), etiology of periodontitis (EBV and CMV), and inflammatory marker of periodontitis (PTX3) were found to be significantly elevated in CAD. These findings suggests that periodontal diseases may be a risk factor that could influence the progression of CAD.

J Periodontal Res 2024; 59:387-394. [PMID: 38126217 DOI: 10.1111/jre.13223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 11/29/2023] [Accepted: 12/01/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVE The purpose of the present research is to evaluate the salivary levels of leucine-rich alpha-2 glycoprotein (LRG) and C-reactive protein (CRP) in periodontal health and disease (gingivitis and stage III periodontitis) and also to compare the discriminative efficiencies of both biomarkers in periodontal disease. BACKGROUND LRG is a new acute-phase protein whose functions are still being investigated. LRG and CRP are both biomarkers that are increased by inflammation. No clinical study has yet investigated the comparison of the level of LRG and CRP in periodontal health, gingivitis and periodontitis in saliva samples. METHODS A total of 60 individuals, including 20 periodontally healthy (control group/group C), 20 with gingivitis (group G), and 20 with Stage III periodontitis (group P), who were systemically healthy and non-smokers, participated in this study. Periodontal charts were used for recording clinical periodontal parameters and saliva LRG and CRP levels were measured by ELISA. Analyzing the area under the curve (AUC) was performed by the receiver-operating characteristics curve. RESULTS Salivary levels of LRG and CRP were significantly higher in disease groups than in group C (p < .05). Positive statistically significant correlations were observed between both biomarkers and clinical parameters (p < .05). There was also a strong positive correlation between two biomarkers (p < .05). In distinguishing periodontal disease from periodontal health, LRG (AUC = 0.833) and CRP (AUC = 0.826) were found to have similar accuracy (p = .923). CONCLUSION LRG and CRP may be useful and similarly effective biomarkers in the diagnosis of periodontal diseases based on the findings of this study.

Abstract
Objectives Pentraxin 3 (PTX3) is a biomarker, associated with the pathogenesis of Periodontitis and coronary artery disease (CAD) individually, but their role in patients with both diseases remains unclear. The current study aims to evaluate the association of PTX in patients with concomitant periodontitis and CAD. Materials and Methods In a case-control study, 240 participants were selected and divided into four groups. Nonperiodontitis + noncardiac = 60 patients, periodontitis + noncardiac (P + NC) = 60 patients, nonperiodontitis + cardiac (NP + C) = 60 patients, periodontitis + cardiac (P + C) = 60 patients. Demographic variables, cardiac and periodontal parameters were recorded. PTX was evaluated in the subgingival plaque and atheromatous plaque samples using real-time quantitative polymerase chain reaction and compared between the groups. The results were statistically analyzed. Results Among the demographic variables, age showed a significant difference between the groups. Systolic and diastolic blood pressure, low-density lipoprotein, and random blood sugar were significantly higher in NP + C and P + C groups (P ≤ 0.05). The plaque index, probing pocket depth, and clinical attachment loss were significantly higher in P + NC and P + C groups (P ≤ 0.05). PTX was significantly elevated in P + C group (P = 0.000). Pearson's correlation revealed a significant correlation between the periodontal parameters and PTX in both the cardiac and oral samples. Conclusion PTX3 levels were elevated in CAD patients with periodontitis suggesting the influence of periodontal inflammation in the progression of CAD. PTX3 may serve as a diagnostic and prognostic tool for both periodontitis and CAD. This study could provide an understanding and awareness about the potential role of PTX3 in both periodontitis and CAD.

Abstract
Saliva is a versatile biofluid that contains a wide variety of biomarkers reflecting both physiologic and pathophysiologic states. Saliva collection is noninvasive and highly applicable for tests requiring serial sampling. Furthermore, advances in test accuracy, sensitivity and precision for saliva has improved diagnostic performance as well as the identification of novel markers especially in oral disease processes. These include dental caries, periodontitis, oral squamous cell carcinoma (OSCC) and Sjögren's syndrome (SS). Numerous growth factors, enzymes, interleukins and cytokines have been identified and are the subject of much research investigation. This review highlights current procedures for successful determination of saliva biomarkers including preanalytical factors associated with sampling, storage and pretreatment as well as subsequent analysis. Moreover, it provides an overview of the diagnostic applications of these salivary biomarkers in common oral diseases.

Abstract
Non-surgical periodontal therapy (NSPT) is the first essential step for the management of any periodontitis patient. This study aims to evaluate the impact of NSPT on pro-inflammatory mediators’ regulation and on clinical parameters in periodontitis patients who suffer from chronic hepatitis C. At baseline, selected patients were clinically evaluated for their periodontal status. A subsequent quantitative assessment of C-reactive protein and pentraxin-3 in samples of gingival fluid was performed by Enzyme-Linked Immunosorbent Assay (ELISA). Afterwards, NSPT was performed. Three months after NSPT, the clinical and ELISA assessments were repeated. The results show an improvement of the clinical parameters in periodontitis patients at the three-month recall. In chronic hepatitis C patients with periodontitis, the gingival fluid levels of pro-inflammatory markers reduced significantly. The targeted markers also expressed significant correlations with the clinical parameters used for the assessment of periodontitis’ severity. The results suggest that, while chronic hepatitis C patients exhibited a more negative periodontal status at baseline as compared to non-hepatitis ones, NSPT is effective in decreasing the local periodontal inflammatory reaction and in proving the periodontal status of this type of patients. Given the limitation of the study, periodontal screening and NSPT should be included in the integrated therapeutical approach of chronic hepatitis C patients, for its impact on the local inflammatory response.

Abstract
Pentraxin-3 (PTX3) is a conserved protein of the innate immune system which has been less studied than the pentraxin C-reactive protein (CRP), but it is of relevance in, for example, vascular pathology and pregnancy morbidities. Since the interest in salivary biomarkers in general is increasing, we asked whether PTX3 could be detected in saliva and if any substantial diurnal variation occurs. In addition, we evaluated association with biomarkers of systemic inflammation (interleukin (IL)-1β, IL-6, and IL-8 and CRP), body mass index (BMI), smoking, and age. PTX3 in morning and evening saliva from 106 middle-aged participants of the general population was investigated by ELISA and total protein levels by spectrophotometry. PTX3 was detectable in saliva, and concentrations varied over the day with higher morning concentrations, but the PTX3 relative protein levels (percentage of total protein) were significantly higher in the evening. Sex and age did not impact salivary PTX3, but smoking was associated with lower PTX3 levels. BMI correlated positively with PTX3 in evening saliva. There was no general association with biomarkers of systemic inflammation, except for IL-6. Salivary PTX3 likely reflects the local inflammatory milieu, and adjustments for sampling time, smoking habits, and BMI are needed to adequately interpret PTX3 in saliva.

Abstract
BACKGROUND Interleukin 22(IL-22), a recently identified, Th-22 associated cytokine has a key role in the production of human β defensin-2(hBD-2) and hence an indirect role in innate, nonspecific immunity. Hence this study was conducted as preliminary research to quantify and correlate the levels of IL-22 and hBD-2 in periodontal disease. MATERIALS AND METHODS Gingival crevicular fluid from subjects with chronic periodontitis (n = 27), gingivitis (n = 25) and healthy controls (n = 27) were obtained for the study. The periodontal status of each subject was assessed by criteria based on plaque index, gingival index, bleeding on probing, probing depth and clinical attachment loss. The levels of IL-22 and hBD-2 were measured in GCF samples with an enzyme-linked immunosorbent assay. RESULT Periodontal parameters were described and reported as mean values. The distribution and comparison of clinical parameters and gingival crevicular fluid IL-22, hBD-2 levels in healthy controls, gingivitis and chronic periodontitis groups were assessed using one way ANOVA test. Post Hoc Bonferroni test was used for intergroup comparisons. Association among the IL-22 , hBD-2 and clinical parameters in all three groups were examined using Pearson's correlation test.The IL-22 level was significantly greater in chronic periodontitis group than healthy controls (P < 0.001) and gingivitis group (P < 0.001). The hBD-2 level was significantly higher in the chronic periodontitis group compared to gingivitis (P = 0.003) and healthy controls (P < 0.001). The results also showed a statistically significant correlation (P = 0.002) between IL-22 and hBD-2 concentration in chronic periodontitis group. CONCLUSION These results indicate the role of IL- 22 and hBD-2 in the innate immune response during periodontitis.

Abstract
The objective of this preclinical in vivo study was to determine changes in vascular inflammatory biomarkers in systemic circulation after injection of lipopolysaccharide (LPS) from Porphyromonas gingivalis (Pg) in rats. Experimental periodontitis was induced by injections of Pg-LPS. Gingival soft and hard tissues changes were analysed by means of magnetic resonance imaging and micro computed tomography. Serum levels of interleukin (IL)-6, IL-10, pentraxin (PTX) 3, and soluble fragment of tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) were determined at baseline and 24 h, 7, 14, and 21 days after periodontal induction. Significant periodontal inflammation and alveolar bone loss were evident at the end of periodontal induction. Experimental periodontitis posed an acute systemic inflammatory response with increased serum levels of IL-6 and PTX3 at 24 h post-induction, followed by a significant overexpression of sTWEAK at 7 days. This inflammatory state was maintained until the end of the experiment (21 days). As expected, IL-10 serum levels were significantly lower during the follow-up compared to baseline concentrations. In the present animal model, experimental periodontitis is associated with increased systemic inflammation. Further studies are needed to confirm whether PTX3 and sTWEAK could be useful biomarkers to investigate potential mechanisms underlying the relationship between periodontitis and atherosclerotic vascular diseases.

Abstract
Pentraxin-3 (PTX3) is recognized as a modulator of inflammation and a mediator of tissue repair. In this study, we characterized the role of PTX3 on some biological functions of human dental pulp stem cells (HDPSCs). The expression level of PTX3 significantly increased during osteogenic/odontogenic differentiation of HDPSCs, whereas the knockdown of PTX3 decreased this differentiation. Silencing of PTX3 in HDPSCs inhibited their migration and C-X-C chemokine receptor type 4 (CXCR4) expression. Our present study indicates that PTX3 is involved in osteogenic/odontogenic differentiation and migration of HDPSCs, and may contribute to the therapeutic potential of HDPSCs for regeneration and repair.

Abstract
The innate immune system is equipped with a number of germ-line encoded soluble pattern recognition molecules (PRMs) that collectively mediate the humoral host response to infection and damage in cooperation with cells and tissues of the immune and non-immune compartments. Despite the impressive diversity in structure, source, and regulation across PRMs, these all share remarkably similar functions inasmuch as they recognize microbes and damaged tissues, activate complement, exert opsono-phagocytic activities, and regulate inflammation. The long pentraxin 3 (PTX3) is a prototypic soluble PRM. Long known as a major player in innate immunity, inflammation and matrix remodeling, only recently has PTX3 emerged as a mediator of bone homeostasis in rodents and humans. Ptx3-targeted mice exhibit reduced trabecular volume during bone development, and impaired callus mineralization following experimental fracture. The murine gene is expressed in vivo by non-hematopoietic periosteal cells in the early phases of fracture healing, and in vitro by maturing osteoblasts. Human osteoblasts do express the PTX3 protein, whose levels positively correlate with bone density in vivo and osteoblast proliferation and maturation in vitro, thus pointing to a role in bone deposition. Contrasting evidence, however, suggest osteoclastogenesis-promoting effects of PTX3, where its expression has been associated with periodontitis, arthritis, and bone metastasis, conditions hallmarked by inflammation and bone resorption. Here, we review past and recent literature on the functions exerted by this long pentraxin in bone biology, with major emphasis on physiological skeletal remodeling, fracture healing, and chronic diseases of the bone.

Severe periodontitis is linked with increased peripheral levels of sTWEAK and PTX3 in chronic migraineurs. Clin Oral Investig 2019; 24:597-606.

Abstract
OBJECTIVES Periodontitis (PD) and chronic migraine (CM) have been recently linked, and inflammatory processes and vascular endothelial changes are hypothesized as potential mediators of this relationship. The aim of this cross-sectional analysis was to investigate the potential association of PD with vascular systemic inflammation and complement activation in patients with CM. MATERIALS AND METHODS Ninety-four chronic migraineurs underwent a full-mouth periodontal evaluation and a measure of PD activity and severity, namely the periodontal inflamed surface area (PISA) was calculated for each patient. We divided CM patients according to their periodontal status: mild PD (N = 14), moderate PD (N = 22), severe PD (N = 19), and non-PD (N = 39). Serum levels of C-reactive protein (CRP), pentraxin 3 (PTX3), soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK), and complements C3 and C4 were measured outside of migraine attacks. RESULTS We found that severe periodontal patients had significantly higher circulating levels of PTX3 and sTWEAK compared with those without PD (2475.3 ± 1646.8 pg/mL vs. 516.6 ± 1193.8 pg/mL, P < 0.0001 and 672.4 ± 118.2 pg/mL vs. 485.7 ± 112.2 pg/mL, P < 0.0001; respectively). For the remaining biomarkers, no significant differences were found between groups. Severe PD was independently associated with higher levels of PTX3 (β = 1997.6, P < 0.0001) and sTWEAK (β = 187.1, P < 0.0001) but not with CRP, C3, and C4. PISA positively correlated to PTX3 (r = 0.475, P < 0.0001) and sTWEAK (r = 0.386, P < 0.0001). CONCLUSIONS Based on these preliminary results, severe PD was linked with vascular systemic inflammation in patients with CM. However, further longitudinal studies should be performed to confirm these findings. CLINICAL RELEVANCE sTWEAK and PTX3 measured in serum could be used as biomarkers in the PD-CM link.

Abstract
OBJECTIVES Orthodontic treatment consists of numerous appliance activations that rely on stimulation of osteoclasts at alveolar bone sites. However, the action of osteoclast-like cells on dentin ("odontoclasts") is a pathological side effect of orthodontic treatment. The aim of this article is twofold: (a) To report preliminary results from ongoing cell culture experiments to identify unique markers of dentin resorption, and (b) To discuss our work using nanoparticle tracking analysis (NTA) and exosomes for developing biological fluid-based biopsies to monitor clastic cell activity. SETTING AND SAMPLE POPULATION Twelve healthy volunteers in permanent dentition. MATERIAL AND METHODS For the in vitro experiments, murine clastic cell precursors were cultured on dentin or bone slices for 7 days and phage-display biopanning was used to identify molecular surface differences between osteoclasts and odontoclasts. In the human study, gingival crevicular fluid (GCF) samples were collected using different tools and analysed for protein and exosome recovery. RESULTS Biopanning generated antibody fragments that were uniquely reactive to odontoclasts. Numerous nanoparticles in the size range of exosomes were detected in all of the human GCF samples. CONCLUSIONS Our results support that there are molecular differences between osteoclasts and odontoclasts. Emerging technologies may allow the use of exosomes in GCF as a clinical tool to detect markers of root resorption.

Abstract
INTRODUCTION Pentraxin 3 (PTX3) has been suggested as a novel inflammatory biomarker in inflammation-associated diseases. The aim of this study was to examine the role of PTX3 in the inflammatory response of human dental pulp cells (HDPCs). METHODS HDPCs were treated with tumor necrosis factor alpha (TNF-α), and total RNA and protein were extracted. PTX3 messenger RNA and protein expression levels were analyzed using reverse transcription polymerase chain reaction and Western blotting, respectively. For PTX3 knockdown, HDPCs were transfected with a small interfering RNA against human PTX3. Macrophage chemotaxis after PTX3 silencing in HDPCs was assessed by transwell migration assays. RESULTS TNF-α increased PTX3 messenger RNA and protein levels in HDPCs. TNF-α-induced PTX3 expression was mediated by extracellular signal-regulated kinase 1/2 and nuclear factor kappa B. PTX3 knockdown decreased the expression levels of interleukin 6, interleukin 8, and monocyte chemoattractant protein 1 after stimulation with TNF-α in HDPCs. Moreover, PTX3 silencing in HDPCs significantly decreased the chemotactic migration of macrophages. CONCLUSIONS Our findings indicate PTX3 plays a critical role in the regulation of pulp inflammatory processes and reveal its underlying molecular mechanism.

Abstract
OBJECTIVES The aim of this randomized split-mouth clinical trial was to evaluate the effects of ozone therapy on clinical and biochemical parameters of moderate to severe generalized periodontitis patients after non-surgical periodontal therapy. METHODS A total of 36 moderate to severe generalized periodontitis patients were included in the study. The patients were systemically healthy and 18 to 64 years of age. Periodontal parameters, including plaque index (PI), gingival index (GI), probing depth (PD), percentage of bleeding on probing, percentage of pockets deeper than 5 mm and clinical attachment level (CAL), and percentage of ≥3 mm CAL, were evaluated at baseline and 3 months following periodontal therapy. All participants were treated non-surgically. Topical gaseous ozone was applied into periodontal pockets twice a week for 2 weeks during active periodontal therapy. Gingival crevicular fluid pentraxin-3 (PTX-3), interleukin-1β (IL-1β), and high sensitivity C-reactive protein (Hs-CRP) were evaluated. All statistical data were analyzed using SPSS software. RESULTS Total of 36 participants completed the study (18 males, 18 females). PI, GI, PD, percentage of bleeding on probing, percentage of pockets deeper than 5 mm and CAL, and percentage of ≥3 mm CAL were improved, and there were no significant differences between the two sides. All inflammatory parameters, PTX-3, Hs-CRP, and IL-1, were reduced at 3-month follow-up. Only the decrease in PTX-3 levels between baseline and 3-month follow-up was statistically significant. CONCLUSIONS Ozone therapy did not have any additional effect on periodontal parameters. All cytokines were reduced after periodontal therapy. Only PTX-3 levels were significantly lower at ozone sites compared to those at the control sites.

Abstract
Host-derived pattern recognition receptors (PRRs) are necessary for effective innate immune engagement of pathogens that express microbial-associated molecular patterns (MAMP) ligands for these PRRs. This study used a nonhuman primate model to evaluate the expression of these sensing molecules in gingival tissues. Macaca mulatta aged 12-24 with a healthy periodontium (n = 13) or periodontitis (n = 11) provided gingival tissues for assessment of naturally-occurring periodontitis. An additional group of animals (12-23 years; n = 18) was subjected to a 5 month longitudinal study examining the initiation and progression of periodontitis, RNA was isolated and microarray analysis conducted for gene expression of the sensing PRRs. The results demonstrated increased expression of various PRRs in naturally-occurring established periodontitis. Selected PRRs also correlated with both bleeding on probing (BOP) and pocket depth (PD) in the animals. The longitudinal model demonstrated multiple TLRs, as well as selected other PRRs that were significantly increased by 2 weeks during initiation of the lesion. While gene expression levels of various PRRs correlated with BOP and PD at baseline and resolution of disease, few correlated with these clinical parameters during initiation and progression of the lesion. These findings suggest that the levels of various PRRs are affected in established periodontitis lesions, and that PRR expression increased most dramatically during the initiation of the disease process, presumably in response to the juxtaposed microbial challenge to the tissues and goal of reestablishing homeostasis.

Abstract
Objectives One of the plausible mechanisms in the relationship between periodontitis and coronary artery disease (CAD) is the systemic inflammatory burden comprised of circulating cytokines/mediators related to periodontitis. This study aims to test the hypothesis that periodontal inflamed surface area (PISA) is correlated with higher circulating levels of acute phase reactants (APR) and pro-inflammatory cytokines/mediators and lower anti-inflammatory cytokines/mediators in CAD patients. Material and Methods Patients aged from 30 to 75 years who underwent coronary angiography with CAD suspicion were included. Clinical periodontal parameters (probing depth - PD, clinical attachment loss, and bleeding on probing - BOP) were previously recorded and participants were divided into four groups after coronary angiography: Group 1: CAD (+) with periodontitis (n=20); Group 2: CAD (+) without periodontitis (n=20); Group 3: CAD (-) with periodontitis (n=21); Group 4: CAD (-) without periodontitis (n = 16). Serum interleukin (IL) -1, -6, -10, tumor necrosis factor (TNF)-α, serum amyloid A (SAA), pentraxin (PTX) 3, and high-sensitivity C-reactive protein (hs-CRP) levels were measured with ELISA. Results Groups 1 and 3 showed periodontal parameter values higher than Groups 2 and 4 (p<0.0125). None of the investigated serum parameters were statistically significantly different between the study groups (p>0.0125). In CAD (-) groups (Groups 3 and 4), PISA has shown positive correlations with PTX3 and SAA (p<0.05). Age was found to predict CAD significantly according to the results of the multivariate regression analysis (Odds Ratio: 1.17; 95% Confidence Interval: 1.08-1.27; p<0.001). Conclusions Although age was found to predict CAD significantly, the positive correlations between PISA and APR in CAD (-) groups deserve further attention, which might depend on the higher PISA values of periodontitis patients. In further studies conducted in a larger population, the stratification of age groups would provide us more accurate results.

Abstract
Pentraxin 3 (PTX3) is an inflammatory mediator acting as a fluid-phase pattern recognition molecule and playing an essential role in innate immunity and matrix remodeling. Inflammatory mediators also contribute to skeletal homeostasis, operating at multiple levels in physiological and pathological conditions. This study was designed to investigate the role of PTX3 in physiological skeletal remodeling and bone healing. Micro-computed tomography (μCT) and bone histomorphometry of distal femur showed that PTX3 gene-targeted female and male mice (ptx3−/−) had lower trabecular bone volume than their wild-type (ptx3+/+) littermates (BV/TV by μCT: 3.50 ± 1.31 vs 6.09 ± 1.17 for females, p < 0.0001; BV/TV 9.06 ± 1.89 vs 10.47 ± 1.97 for males, p = 0.0435). In addition, μCT revealed lower trabecular bone volume in second lumbar vertebra of ptx3−/− mice. PTX3 was increasingly expressed during osteoblast maturation in vitro and was able to reverse the negative effect of fibroblast growth factor 2 (FGF2) on osteoblast differentiation. This effect was specific for the N-terminal domain of PTX3 that contains the FGF2-binding site. By using the closed transversal tibial fracture model, we found that ptx3−/− female mice formed significantly less mineralized callus during the anabolic phase following fracture injury compared to ptx3+/+ mice (BV/TV 17.05 ± 4.59 vs 20.47 ± 3.32, p = 0.0195). Non-hematopoietic periosteal cells highly upregulated PTX3 expression during the initial phase of fracture healing, particularly CD51+ and αSma+ osteoprogenitor subsets, and callus tissue exhibited concomitant expression of PTX3 and FGF2 around the fracture site. Thus, PTX3 supports maintenance of the bone mass possibly by inhibiting FGF2 and its negative impact on bone formation. Moreover, PTX3 enables timely occurring sequence of callus mineralization after bone fracture injury. These results indicate that PTX3 plays an important role in bone homeostasis and in proper matrix mineralization during fracture repair, a reflection of the function of this molecule in tissue homeostasis and repair.

Abstract
Host-bacterial interactions at mucosal surfaces require recognition of the bacteria by host cells enabling targeted responses to maintain tissue homeostasis. It is now well recognized that an array of host-derived pattern recognition receptors (PRRs), both cell-bound and soluble, are critical to innate immune engagement of microbes via microbial-associated molecular patterns (MAMP). This report describes the use of a nonhuman primate model to evaluate changes in the expression of these sensing molecules related to aging in healthy gingival tissues. Macaca mulatta aged 3-24 years were evaluated clinically and gingival tissues obtained, RNA isolated and microarray analysis conducted for gene expression of the sensing pattern recognition receptors (PRRs). The results demonstrated increased expression of various PRRs in healthy aging gingiva including extracellular (CD14, CD209, CLEC4E, TLR4), intracellular (NAIP, IFIH1, DAI) and soluble (PTX4, SAA1) PRRs. Selected PRRs were also correlated with both bleeding on probing (BOP) and pocket depth (PD) in the animals. These findings suggest that aged animals express altered levels of various PRRs that could affect the ability of the tissues to interact effectively with the juxtaposed microbial ecology, presumably contributing to an enhanced risk of periodontitis even in clinically healthy oral mucosal tissues with aging.

Abstract
Context: Inflammation is a common feature of both peripheral artery disease (PAD) and periodontal disease. Aim: The aim of this study is to evaluate the relationship between PAD and periodontal disease by examining the levels of inflammatory cytokines, pentraxin-3 (PTX-3), and high-sensitive C-reactive protein from serum. Materials and Methods: A total of 50 patients were included in this cross-sectional study. Patients were divided into two groups: those with PAD (test group) and those with the non-PAD group (control group) based on ankle–brachial index values. Periodontal examinations and biochemical analysis for PTX-3 and high-sensitive C-reactive protein were performed to compare the two groups. Statistical Analysis Used: All the obtained data were sent for statistical analyses using SPSS version 18. Results: In the clinical parameters, there is statistically significant difference present between plaque index, clinical attachment loss, and periodontal inflammatory surface area with higher mean values in patients with PAD having periodontitis. There is statistical significant (P < 0.01) difference in all biochemical parameters (P < 0.05) considered in the study between PAD patients and non-PAD patients with higher mean values of total cholesterol (TC), low-density lipoprotein (LDL), high-sensitive C-reactive protein (hs-CRP), and PTX-3. Conclusion: PTX-3 and acute-phase cytokine such as hs-CRP can be regarded as one of the best indicators to show the association between the PAD and periodontitis followed by hs-CRP, TC, very LDL (VLDL), and LDL. However, high-density lipoprotein (HDL) is a poor indicator for its association with chronic periodontitis and PAD.

Abstract
AIM Orthodontic treatment is routinely carried out in patients with the purpose of correcting various forms of dental malocclusions. Retraction of the canines can be achieved either individually or along with incisor. Pentraxin-3 (PTX-3) is regarded as the true independent indicator of disease activity. Hence, we undertook the present study to assess and compare the level of PTX-3 in patients undergoing canine retraction with active tieback and Nickel-Titanium (NiTi) coil spring. MATERIALS AND METHODS The present study included assessment of 25 patients that underwent canine retraction as a part of fixed orthodontic treatment. In the maxillary right and left quadrant, active tieback and NiTi coil spring were used respectively. Gingival crevicular fluid samples were collected 1 hour prior to the commencement of orthodontic canine retraction procedure followed by collection at following time intervals: 1 hour, 1, 7, and 14 days after the start of canine retraction procedure. Enzyme-linked immunosorbent assay kit was used for analysis of the samples as per manufacturer's instructions. All the data were recorded and compiled. All the results were analyzed by Statistical Package for the Social Sciences software. RESULTS Nonsignificant difference was observed in the values of PTX-3 at baseline and 1 hour. While comparing the mean PTX-3 values between different time intervals in both the study groups, significant difference was observed. CONCLUSION In comparison to the active tieback, NiTi coil exhibited faster space closure rate. CLINICAL SIGNIFICANCE In patients undergoing orthodontic treatment, PTX-3 is associated with periodontal remodeling under the effect of orthodontic forces.

Abstract
INTRODUCTION Periodontal diseases are inflammatory in nature involving interplay between the bacterial plaque and the micro-organisms, with the response of the host playing a pivotal role in either attenuating or eliminating the disease. Rheumatoid Arthritis (RA) is also a chronic inflammatory disease which shares common risk factors with periodontitis. Porphyromonas Gingivalis and Pentraxin 3 (an acute inflammatory protein) have been observed to be associated with both the diseases. AIM This study was done to determine if there was any association between Pophyromonas Gingivalis and Pentraxin 3 levels in patients with RA and Chronic Periodontitis in comparison with Healthy controls. MATERIALS AND METHODS This observational study was conducted on 90 subjects (42 Males and 48 Females) aged between 30-60 years. The subjects were selected from the out patient ward of a tertiary referral care hospital. The selected subjects were equally divided into three groups. Group I: Comprising of 30 patients with RA and chronic periodontitis who were in turn, subdivided into Group I- A (n=15) -Patients just diagnosed with RA and Group I- B (n=15) Patients under medications for more than three months. Group II: Patients with Chronic Periodontitis (n=30) and Group III: Healthy Controls (n=30) Intergroup comparison for continuous data was done by One-way analysis of variance test followed by Bonferroni's post-hoc test. Intragroup comparison for continuous data was done by paired t-test. RESULTS Intergroup comparison between Group I and Group II did not show any statistical difference pertaining to the clinical parameters except for the Gingival Index (GI) which was found to be higher in Group II (Mean= 2.07) when compared to Group I (Mean=1.59). Intragroup comparison between Group IA and Group IB was statistically significant for GI, Plaque Index (PI), and Clinical Attachment Levels (CAL). Intragroup comparison between Group I-A and Group I-B showed that both Porphyromonas gingivalis and Pentraxin 3 Levels were higher in Group I- A. CONCLUSION In this study, it was observed that there was a positive association between Porphyromonas gingivalis and Pentraxin 3 levels in patients with rheumatoid arthritis and periodontitis.

Abstract
Migraine is a hereditary constitutional base disorder, which is characterized by recurrent episodes of headache pulsatile characteristics associated with photophobia/phonophobia, nausea and/or vomiting. The main complication in migraine is the chronicity of the process, now recognized as a chronic migraine. Although pathogenic mechanisms that may influence the pathophysiology of migraine and its possible chronicity are not fully understood, previous studies have shown in patients with migraine molecular alterations of systemic inflammation, neurogenic inflammation, endothelial dysfunction, innate immunity, dysfunction of matrix proteases and blood-brain barrier. Periodontal disease is an inflammatory lesion caused by bacteria. After the bacterial infection begins, an immune response that will be responsible for individual susceptibility appears. More advanced forms of periodontitis have demonstrated molecular alterations of inflammation, endothelial dysfunction, dysfunction of matrix proteases and innate immunity, similar to those observed in migraine. Furthermore, the main molecular mediators of neurogenic inflammation related to activation of the trigeminovascular system, which are characteristic of migraine, are overexpressed in gingival crevicular fluid and mucosa in patients with periodontal disease. Hypertension, hypercholesterolemia, insulin resistance, stroke or coronary artery disease are comorbidities that periodontal disease and migraine could share. Therefore, several mechanisms and hypotheses could explain the possible association between both diseases. However, epidemiological and molecular studies will be necessary to provide a better understanding of this potential association, which could be implicated in the chronification of migraine.

Abstract
Background. Several studies in the last decades have focused on finding a precise method for the diagnosis of periodontal disease in its early stages. Aim. To evaluate from current scientific literature the most common and precise method for gingival crevicular fluid (GCF) sample collection, biomarker analytical methods, and the variability of biomarker quantification, even when using the same analytical technique. Methodology. An electronic search was conducted on in vivo studies that presented clinical data on techniques used for GCF collection and biomarker analysis. Results. The results showed that 71.1%, 24.7%, and 4.1% of the studies used absorption, microcapillary, and washing techniques, respectively, in their gingival crevicular fluid collection. 73.1% of the researchers analyzed their samples by using enzyme-linked immunosorbent assay (ELISA). 22.6%, 19.5%, and 18.5% of the researchers included interleukin-1 beta (IL-1β), matrix metalloproteinase-8 (MMP-8), and tumor necrosis factor-alpha (TNF-α), respectively, in their studies as biomarkers for periodontal disease. Conclusion. IL-1β can be considered among the most common biomarkers that give precise results and can be used as an indicator of periodontal disease progression. Furthermore, paper strips are the most convenient and accurate method for gingival crevicular fluid collection, while enzyme-linked immunosorbent assay can be considered the most conventional method for the diagnosis of biofluids.

Abstract
Background. Wound healing is a tissue repair process after an injury, and two of its main components are inflammation and angiogenesis, in which course a cascade of mediators is involved. The aim of this research was to evaluate the involvement of Pentraxin 3 and Thrombospondin 1 in wound healing after periodontal surgery (gingivectomy) for gingival overgrowth during orthodontic treatment with or without magnification devices, by assessing their levels in GCF. Methods. From 19 patients with gingival overgrowth as a result of fixed orthodontic treatment, the overgrown gingiva was removed by gingivectomy, from one half of the mandibular arch without magnification and from the other under magnification. Pentraxin 3 and Thrombospondin 1 were determined from gingival crevicular fluid by ELISA tests. Results. Statistically significant differences (p < 0.05) and correlations between levels of the two biomarkers were analyzed. Statistically significant differences were established between levels of the two biomarkers at different time points, with significant positive correlation at the point of 24 hours. Conclusions. Within the limitations of this study, the results seem to sustain the involvement of Pentraxin 3 and Thrombospondin 1 in the processes of inflammation and angiogenesis in wound healing of patients with postorthodontic gingivectomy. The dynamics of Pentraxin 3 and Thrombospondin 1 levels could suggest a reduced inflammation and a faster angiogenesis using microsurgery.

Abstract
Objectives: To compare the levels of pentraxin 3 (PTX-3) in gingival crevicular fluid (GCF) in patients undergoing orthodontic canine retraction with active tieback and nickel titanium (NiTi) coil spring. Materials and Methods: Fifteen patients of the age group 15–25 years with first premolar extraction undergoing canine retraction were selected. One month after placement of 0.019” × 0.025” stainless steel wire, canine retraction was started with active tieback (150 g force) on upper right quadrant and NiTi coil spring (150 g force) on upper left quadrant. GCF samples were collected 1 h before commencement of canine retraction and thereafter at intervals of 1 h, 1 day, 1 week, and 2 weeks after application of force. The collected GCF was eluted from the microcapillary pipette in 100 μl phosphate-buffered saline (pH 5–7.2). The samples were analyzed for PTX-3 levels by the ELISA technique. Results: The mean levels of PTX-3 at 1 h before canine retraction (baseline) was 1.30 ± 0.22 ng/ml and at 1 h 1.66 ± 0.33 ng/ml, 1 day 2.65 ± 0.09 ng/ml, 1 week 1.96 ± 0.15 ng/ml, and 2 weeks 1.37 ± 0.18 ng/ml in active tieback group. The mean levels of PTX-3 at 1 h before canine retraction was 1.32 ± 0.30 ng/ml, and at 1 h 1.71 ± 0.39 ng/ml, 1 day 2.78 ± 0.12 ng/ml, 1 week 2.52 ± 0.18 ng/ml, and 2 weeks 2.12 ± 0.17 ng/ml in NiTi coil spring group. A significant difference of P < 0.001 was found in PTX-3 levels in GCF during canine retraction between active tieback and NiTi coil spring at 1 day, 1 week, and 2 weeks. Conclusion: The results showed that PTX-3 levels increased from 1 h after application of orthodontic force and reached peak at 1 day, followed by a gradual decrease at 1 week and 2 weeks in both active tie back and NiTi coil spring groups.

Abstract
Although historically viewed as merely anti-microbial effectors in acute infection or injury, neutrophils are now appreciated to be functionally versatile with critical roles also in chronic inflammation. Periodontitis, a chronic inflammatory disease that destroys the tooth-supporting gums and bone, is particularly affected by alterations in neutrophil numbers or function, as revealed by observations in monogenic disorders and relevant mouse models. Besides being a significant debilitating disease and health burden in its own right, periodontitis is thus an attractive model to dissect uncharted neutrophil-associated (patho)physiological pathways. Here, we summarize recent evidence that neutrophils can contribute to inflammatory bone loss not only through the typical bystander injury dogma but intriguingly also through their absence from the affected tissue, where they normally perform important immunomodulatory functions. Moreover, we discuss recent advances in the interactions of neutrophils with the vascular endothelium and - upon extravasation - with bacteria, and how the dysregulation of these interactions leads to inflammatory tissue damage. Overall, neutrophils have both protective and destructive roles in periodontitis, as they are involved in both the maintenance of periodontal tissue homeostasis and the induction of inflammatory bone loss. This highlights the importance of developing approaches that promote or sustain a fine balance between homeostatic immunity and inflammatory pathology.

Abstract
Acute phase proteins are a class of proteins whose plasma concentration increase (positive acute phase proteins) or decrease (negative acute phase proteins) in response to inflammation. This response is called as the acute phase reaction, also called as acute phase response, which occurs approximately 90 minutes after the onset of a systemic inflammatory reaction. In Periodontitis endotoxins released from gram negative organisms present in the sub gingival plaque samples interact with Toll- like receptors (TLR) that are expressed on the surface of Polymorphonuclear leucocytes (PMNs) and monocytes which are in abundance in periodontal inflammation. The complex formed due to interaction of Endotoxins and TLR activates the Signal transduction pathway in both innate and adaptive immunity resulting in production of Cytokines that co- ordinate the local and systemic inflammatory response. The pro inflammatory cytokines originating at the diseased site activates the liver cells to produce acute phase proteins as a part of non specific response. The production of Acute phase proteins is regulated to a great extent by Cytokines such as IL-1, IL-6, IL-8, TNF-α and to a lesser extent by Glucocorticoid hormones. These proteins bind to bacteria leading to activation of complement proteins that destroys pathogenic organisms. Studies have shown that levels of acute phase proteins are increased in otherwise healthy adults with poor periodontal status. This article highlights about the synthesis, structure, types and function of acute phase proteins and the associated relation of acute phase proteins in Periodontitis.

Resistin: a potential biomarker for periodontitis influenced diabetes mellitus and diabetes induced periodontitis. DISEASE MARKERS 2014; 2014:930206.

Abstract
Biomarkers are highly specific and sensitive indicators of disease activity. Resistin is a recently discovered adipocytokine, having a potent biomarker quality. Initially resistin was thought to be produced by adipocytes alone; however, emerging evidence suggests that it is also produced in abundance by various cells of the immunoinflammatory system, indicating its role in various chronic inflammatory diseases. Data suggests that resistin plays a role in obesity, insulin resistance, cardiovascular diseases, and periodontitis. Resistin derived its name from the original observation that it induced insulin resistance (resist-in: resist insulin) in mice and is downregulated in mature murine adipocytes cultured in the presence of insulin sensitizing drugs like thiazolidinediones. It is well recognized that obesity, is associated with insulin resistance and diabetes. A three-way relationship has been established between diabetes, obesity and periodontitis. Recent evidence also suggests an association between obesity and increased risk for periodontitis. Our previous research showed incremental elevation of resistin with periodontal disease activity and a reduced level of resistin, after periodontal therapy. Thus resistin would be one of the molecular links connecting obesity, periodontitis, and diabetes and may serve as a marker that links periodontal disease with other systemic diseases. A Medline/PubMed search was carried out for keywords “Diabetes Mellitus,” “Periodontitis,” and “Resistin,” and all relevant research papers from 1990 in English were shortlisted and finalized based on their importance. This review provides an insight into the biological action of resistin and its possible role in periodontitis influenced diabetes mellitus and diabetes induced periodontitis.

Abstract
Background: Conventional non-surgical periodontal therapy has been proven to be an effective treatment for patients with chronic periodontitis. Tea tree oil (TTO) can be used as adjunct to conventional periodontal therapy in patient with chronic periodontitis. The aim of this study was to evaluate the effectiveness of adjunctive treatment of TTO on the clinical parameters and the level of pentraxin-3 (PTX3) in chronic periodontitis. Materials and Methods: A total of 40 patients with moderate to severe chronic periodontitis were divided into two groups, Group I received scaling and root planing (SRP) only, Group II received SRP and TTO gel. Clinical parameters were recorded and gingival crevicular fluid (GCF) samples were collected from each subject for measuring PTX3 levels at baseline, 1, 3 and 6 months after treatment. Results: In all evaluation periods, there was statistically significant reduction in each of the studied clinical parameters and PTX3 level in Group II as compared with Group I. Conclusions: The local delivery of TTO gel in case of chronic periodontitis may have some beneficial effects to augment the results of the conventional periodontal therapy. Moreover, it places a focus on the value of monitoring GCF levels of PTX3 as a marker of periodontal tissue healing.

Abstract
Periodontitis is an infectious inflammatory disease that destroys the tooth-supporting (periodontal) tissues. Porphyromonas gingivalis is an oral pathogen highly implicated in the pathogenesis of this disease. It can exert its effects to a number of cells, including osteogenic bone marrow stromal cells which are important for homeostastic capacity of the tissues. By employing gene microarray technology, this study aimed to describe the overall transcriptional events (>2-fold regulation) elicited by P. gingivalis secreted products in bone marrow stromal cells, and to dissect further the categories of genes involved in bone metabolism, inflammatory and immune responses. After 6 h of challenge with P. gingivalis, 271 genes were up-regulated whereas 209 genes were down-regulated, whereas after 24 h, these numbers were 259 and 109, respectively. The early (6 h) response was characterised by regulation of genes associated with inhibition of cell cycle, induction of apoptosis and loss of structural integrity, whereas the late (24 h) response was characterised by induction of chemokines, cytokines and their associated intracellular pathways (such as NF-κB), mediators of connective tissue and bone destruction, and suppression of regulators of osteogenic differentiation. The most strongly up-regulated genes were lipocalin 2 (LCN2) and serum amyloid A3 (SAA3), both encoding for proteins of the acute phase inflammatory response. Collectively, these transcriptional changes elicited by P. gingivalis denote that the fundamental cellular functions are hindered, and that the cells acquire a phenotype commensurate with propagated innate immune response and inflammatory-mediated tissue destruction. In conclusion, the global transcriptional profile of bone marrow stromal cells in response to P. gingivalis is marked by deregulated homeostatic functions, with implications in the pathogenesis of periodontitis.

Abstract
Objective. Pentraxin 3 (PTX3), newly discovered inflammation marker, is a member of acute-phase proteins. The hypothesis, synthesis of gingival tissue and serum PTX-3 increases in the experimental periodontitis model (with 10-day and 40-day periods), was tested by detecting gingival tissue and serum PTX-3 levels in rats with experimental periodontitis. Methods. Thirty rats were randomly divided into three groups of ten animals each: ligature-induced experimental periodontitis groups (with 10-day (Group1) and 40-day periods (Group2)) and healthy group (Group3). At the end of experimental period, rats were sacrificed, and radiological and histomorphometric analyses were performed on the mandibles. PTX3 levels were measured in gingival tissue and serum samples using ELISA. Plasma fibrinogen levels were measured according to the nephelometric method. Results. Significant alveolar bone resorption and periodontal inflammation were evident in periodontitis groups. Levels of PTX3 in gingival tissue were statistically higher in Group 1 than those in groups 2 and 3 (P < 0.01). No significant difference was found in serum PTX3 levels between experimental periodontitis and control groups (P > 0.05). Plasma fibrinogen levels were significantly increased in the experimental periodontitis groups (P < 0.001). Conclusion. PTX3 seems to be associated with tissue destruction in earlier periods of inflammatory periodontal disease, contrary to the fibrinogen findings.

Abstract
OBJECTIVES To measure the levels of pentraxin-3 (PTX-3) in gingival crevicular fluid (GCF) in orthodontic young and adult patients in the first 2 weeks after the orthodontic appliance to determine whether those changes occur during orthodontic treatment and if those values could be the expression of an inflammatory state. MATERIALS AND METHODS GCF samples were collected with paper strips from 16 orthodontic young patients and 13 orthodontic adult patients from an upper canine requiring distalization as a test tooth. A contralateral canine was used as a control tooth. The absorbed volume was eluted in 100 µL phosphate-buffered saline (pH = 7.2). PTX-3 levels in GCF were determined using a commercial enzyme-linked immunosorbent assay kit, and the results were expressed in ng/mL. RESULTS The results showed an increase of GCF levels of PTX-3 from 1 hour before the orthodontic appliance to a maximum at 24 hours, followed by a decrease in both groups of adult and young patients. CONCLUSIONS The results suggest PTX-3 involvement in periodontal orthodontic remodeling and the aseptic inflammation induced by the orthodontic forces.

Abstract
BACKGROUND Pentraxins are classical mediators of inflammation and markers of acute-phase reactions. Pentraxin-3 (PTX3) is believed to be a true independent indicator of disease activity. It has been associated with clinical outcomes in incident chronic kidney disease (CKD) and periodontal diseases. Periodontitis is lately being considered as a risk factor for CKD. However, no data are available on elevated PTX3 in patients with CKD associated with periodontitis. METHOD Sixty subjects were divided into three groups (n = 20) based on glomerular filtration rate (GFR) and periodontal parameters: healthy (group-1), CKD (group-2), and CKD with periodontitis (group-3). Plasma samples obtained from each patient were quantified for PTX3 using Enzyme-linked Immunosorbent Assay (ELISA). RESULTS Both patient groups with CKD had higher plasma PTX3 concentrations than control subjects. However, there was no significant difference between the two groups (groups 2 and 3). In all groups, plasma PTX3 correlated positively with periodontal parameters. Group 3 patients had higher concentrations of PTX3 (6.338 ng/ml) than group 2 (5.41 ng/ml) and group 1 (1.835 ng/ml). CONCLUSIONS Within the limits of the present study, the difference in plasma PTX3 levels between groups 2 and 3 was not found to be statistically significant (P > 0.05). However, as PTX3 values correlated positively with periodontal parameters, this model could contribute to identifying individuals with periodontitis at high risk of CKD. Thus, periodontal disease could serve as a risk factor for developing CKD. Further large-scale studies nullifying the confounders for CKD are warranted to confirm positive results.
