J Periodontal Res 2024; 59:480-490. [PMID: 38356138 DOI: 10.1111/jre.13243] [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: 11/05/2023] [Revised: 01/23/2024] [Accepted: 01/25/2024] [Indexed: 02/16/2024]
Abstract
BACKGROUND AND OBJECTIVE Periodontitis is an inflammatory disease that destroys periodontal tissues. Interleukin-20 (IL-20), on the other hand, is known as a potent angiogenic, chemotactic, and pro-inflammatory cytokine associated with various chronic inflammatory disorders. IL-20 has a significant role in the regulation of osteoclastogenesis and osteoblastogenesis. This study aimed to evaluate the effect of IL-20 on periodontal destruction. METHODS In this study, a total of 60 participants were included, 30 of whom were systemically and periodontally healthy (control group), and 30 were systemically healthy but had periodontitis (periodontitis group). Gingival crevicular fluid (GCF) and serum samples were collected from the participants for biochemical analysis. Enzyme-linked immunosorbent assay was used to determine the levels of IL-20, tumor necrosis factor (TNF)-α, IL1β/IL-10, RANKL/osteoprotegerin (OPG), and matrix metalloproteinase-8 (MMP8). For statistical analysis, the independent t-test, Pearson correlation coefficients, and the Chi-square test were used. RESULTS GCF IL-20, RANKL, RANKL/OPG, serum IL-20, RANKL, RANKL/OPG, MMP-8, TNF-α, IL-1B, and IL-1β/IL-10 values were found to be statistically significantly higher in the periodontitis group than in the control group. GCF OPG and serum IL-10 values were found to be statistically significantly higher in the control group than in the periodontitis group. No statistically significant difference was observed between the groups in serum OPG values. A statistically significantly positive correlation was observed between serum IL-20 value and serum RANKL, RANKL/OPG, MMP-8, TNF-α, IL-1β values, and periodontal clinical parameters. The ROC curves showed: AUC = 0.788 for GCF IL-20, and AUC = 1.000 for serum IL-20. CONCLUSION According to the results of the study, IL-20 was found to be associated with periodontitis. The role of IL-20 in periodontal pathogenesis is related to osteoclastogenesis and collagen degradation. It is conceivable that IL-20 may increase bone destruction by both affecting the RANKL/OPG ratio and proinflammatory cytokines.

Abstract
BACKGROUND The study aimed to analyze cytokine levels, including interleukin (IL)-1β, IL-10, and IL-36γ, to investigate the link between pro- and anti-inflammatory responses in periodontal conditions and assess their potential as diagnostic biomarkers for distinguishing between different types of periodontal conditions. METHODS 80 systemically healthy non-smokers (25 periodontally healthy, 25 with gingivitis, 30 with periodontitis) were included. Clinical periodontal parameters were recorded, and gingival crevicular fluid (GCF) samples were obtained. Receiver operating characteristic (ROC) curve analysis was applied to determine the diagnostic value of cytokines. RESULTS IL-36γ had the highest sensitivity for diagnosing periodontitis, although its specificity for identifying those without periodontitis was relatively low. The combination of IL-1β and IL-36γ was the most effective in differentiating periodontitis from periodontal health. IL-10 was found to be an acceptable discriminator for distinguishing gingivitis from healthy conditions. However, its sensitivity and specificity for identifying gingivitis were lower. The combination of the three cytokines showed the highest ability to distinguish between periodontitis and gingivitis. CONCLUSION The levels of IL-1β, IL-10, and IL-36γ in GCF may provide insights into periodontal health and disease status. Further studies are needed to validate these results and explore the potential of these cytokines in periodontal disease management.

Abstract
OBJECTIVE The aim of this study was to assess and correlate the serum and GCF levels of omentin with the periodontal status of rheumatoid arthritis (RA) patients with and without periodontitis. METHODS Forty-four patients were divided into four groups: group H: 11 systemically and periodontally healthy subjects; group P: 11 systemically healthy subjects with periodontitis; group RA: 11 periodontally healthy subjects with rheumatoid arthritis and group RA + P: 11 rheumatoid arthritis subjects with periodontitis. Periodontal parameters (plaque index, modified gingival index, probing depth, and clinical attachment level) were recorded and serum and GCF samples were collected for the estimation of omentin using ELISA. RESULTS The mean value of plaque index, modified gingival index, probing depth, and clinical attachment level were significantly higher whereas serum and GCF omentin levels were found to be decreased in group IV when compared to the other groups. The significant correlation was found between the serum and GCF omentin levels with all the periodontal parameters. CONCLUSION The omentin level in serum and GCF was found to be lower in RA patients with periodontitis. It is also inversely correlated with the periodontal parameters. Thus, omentin can serve as a significant diagnostic and therapeutic tool in both periodontal and rheumatoid disease.

Testosterone replacement relieves ligature-induced periodontitis by mitigating inflammation, increasing pro-resolving markers and promoting angiogenesis in rats: A preclinical study. Arch Oral Biol 2023; 146:105605. [PMID: 36521281 DOI: 10.1016/j.archoralbio.2022.105605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/13/2022] [Accepted: 12/07/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVES This study aimed to evaluate the inflammatory profile as well as the resolution of inflammation in a ligature-induced periodontal inflammation in rats with depletion and/or supraphysiological testosterone replacement. DESIGN Sixty male rats (Holtzman) were used in the present study. Study groups were created as following: (1) Sham (no testicle removal); (2) Orchiectomy (OCX), 3) OCX + Testosterone (OCX + T); (4) Sham + Ligature (SH + L); (5) OCX+L; and 6) OCX + T + L. The surgeries were performed on day 1, and testosterone was administered weekly since day 1. On day 15, a cotton ligature was placed around the lower first molars and maintained for 15 days. Morphological changes in periodontal tissues were determined by histopathological analysis. Immunohistochemistry (factor VIII) and immunoenzymatic assay were performed to evaluate angiogenesis process and (pro- and anti-) inflammatory markers, respectively. RESULTS Ligature promoted a marked inflammatory gingival infiltrate and bone loss (P < 0.05). Supraphysiological testosterone treatment increased the percentage of blood vessels, extracellular matrix and fibroblasts in the presence and absence of periodontal inflammation (P < 0.05). A high dose of testosterone increased factor VIII+ blood vessels and IL-10 expression in inflamed gingival tissue, while PGE2, LXA4 and MPO were reduced as a result of supraphysiological testosterone administration (P < 0.05). CONCLUSIONS These results, in our experimental model, suggest that supraphysiological testosterone treatment stimulated gingival tissue repair during ligature-induced periodontitis, and it seems to be related to an anti-inflammatory and pro-resolutive mechanism resulting by the modulatory effect on PGE2 and IL-10 related to an enhanced angiogenesis.

Abstract
Aim. To study the cytokine profile of the gingival crevicular fluid (GCF) in children with a juvenile rheumatoid arthritis (JRA).Materials and methods. We examined 20 children with JRA and 10 patients without somatic pathology aged 6 to 16 years old. The condition of periodontal tissues was assessed by periodontal indices – gingival index GI (Loe, Silness, 1963) and gingival bleeding index GBI. Biomaterial sampling from the gingival sulcus was carried out using special endodontic absorbent paper points. Enzyme immunoassay for IL-18, IL-10, IL-1ß, IL-1RA, MCP-1, VEGFs in the GCF was performed using the test kits of Vector-Best LLC (Novosibirsk, Russia).Results. Mean GI index in the JRA group was 0.31 ± 0.10 and in the control group – 0.20 ± 0.05 (p < 0.05), mean GBI index – 19.90 ± 3.14 and 10.80 ± 2.60 respectively (p < 0.05), which was accompanied by a more pronounced degree of inflammation of periodontal tissues. The GCF concentration of IL-18 in the JRA group was 6.70 (4.97–7.92) pg/ml, in the control group – 11.25 (8.70–13.10) pg/ml (p < 0.05), while the concentration of IL-1ß was 15.30 (13.79–17.18) pg/ml in the JRA group and 5.36 (5.32–5.54) pg/ml in the control group.The IL-10 concentration in the JRA group was 3.60 (2.89–4.45) pg/ml, which was comparable to the values of the control group. The concentration of IL-1RA was lower in the JRA group than in the control group: 3638.5 (2397.5–4133.5) pg/ml and 4951.0 (4303.0–5455.0) pg/ml respectively. The total GCF chemokine concentration for MCP-1 was determined at the level of 15.65 (14.15–17.39) pg/ml and 15.50 (12.80–21.20) pg/ml for the main and control groups and for VEGF – 49.60 (41.95–54.50) pg/ml in the JRA group and 12.00 (11.00–13.00) pg/ml in control group.Conclusion. In children with juvenile rheumatoid arthritis, an imbalance of pro- and anti-inflammatory cytokines in GCF plays a role in the development of gingivitis: an increased of IL-1ß concentration – a triggering factor of pro-inflammatory chains, a decreased concentration of IL-1RA – an anti-inflammatory cytokine, an increased concentration of VEGF – a marker of hypoxia.

Abstract
OBJECTIVES This study aimed to determine the possible relationship between periodontal disease and ankylosing spondylitis (AS) by evaluating clinical periodontal measurements and gingival crevicular fluid (GCF) levels of sclerostin, interleukin-1β (IL-1ß), and matrix metalloproteinase-8 (MMP-8) levels. MATERIALS AND METHODS Twenty-eight patients with AS (AS group) and 28 systemically healthy controls (C group) were enrolled in this study. Full-mouth periodontal measurements: plaque index, bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL) measurements were obtained from all patients. AS-related parameters were included in the data analyses. An enzyme-linked immunosorbent assay determined GCF IL-1β, MMP-8, and sclerostin levels. RESULTS There were no significant differences in the clinical periodontal measurements between the two groups (p > 0.05). Interestingly, patients with AS had significantly lower GCF sclerostin levels than the C group (p < 0.05). But there were no statistical differences in the GCF levels of IL-1ß and MMP-8 between the two groups (p > 0.05). Serum C-reactive protein (CRP) levels strongly correlated with both BOP (r = 0.497, p < 0.05) and PPD (r = 0.570, p < 0.05) in the AS group. Bath AS Metrology Index (BASMI) also positively correlated with both BOP (r = 0.530, p < 0.05) and CAL (r = 0.568, p < 0.05). Similarly, Maastrıcht Ankylosing Spondylitis Enthesis Score (MASES) strongly correlated with both BOP (r = 0.487, p < 0.05) and CAL (r = 0.522, p < 0.05). CONCLUSION These results suggest that the patient's systemic condition may influence local sclerostin levels in GCF, and the strong correlations between periodontal measurements and AS-related parameters may indicate an interrelationship between inflammatory periodontal disease and AS. CLINICAL RELEVANCE The present study provides important information concerning the relationship between periodontal disease and ankylosing spondylitis.

Abstract
The present work is aimed at exploring the clinical efficacy and safety of methotrexate (MTX) and leflunomide (LEF) combination therapy for rheumatoid arthritis. From June 2019 to June 2021, a total of 120 individuals with rheumatoid arthritis received a diagnosis. Sixty patients each were randomly assigned to the control and observation groups. The observation group received MTX and LEF combo medication while the control group only received MTX treatment. Clinical efficacy, complication incidence, and the alleviation of inflammatory markers, joint pain, and clinical symptoms were compared between the 2 groups. Posttreatment, the observation group had overall response rate of 96.66%, while the control group had 86.67%, with significant differences. Compared with pretreatment, both control and observation group patients showed decreasing trends of IL-1 levels and increasing trends of IL-10 levels posttreatment, with significant differences (
). Compared with the control group, patients in the observation group had lower IL-1 and TNF-α levels with significant differences (
) and higher levels of IL-10 with significant difference (
). In both groups, the pain score and the number of painful joints were much lower than they were prior to treatment. Following treatment, the observation group displayed significantly lower levels of erythrocyte sedimentation rate, rheumatoid factor, and C-reactive protein than the control group (
). Clinical measures in the observation group were all lower than those in the control group with statistically significant differences (
). Moreover, the incidence rate of adverse reactions showed no significant difference between these 2 groups (
). In conclusion, the combination therapy of MTX and LEF is efficacious for rheumatic arthritis.

Abstract
Periodontitis (PD) and rheumatoid arthritis (RA) are causally linked by their common inflammatory responses, yet it is largely unknown if these inflammatory responses might have an impact on salivary metallothionein (MT), zinc (Zn), and calcium (Ca) content. In this study, we analysed salivary concentrations of pro-inflammatory (IFN-γ, IL-6, and IL-17) and anti-inflammatory (IL-4 and IL-10) cytokines, as well as MT, Zn, and Ca in four groups of participants, namely control (without PD or RA, n = 21), PD (n = 21), RA (n = 21), or RAPD (n = 19). As expected, an increased amount of salivary pro-inflammatory cytokines were observed in the PD, RA, and RAPD groups. While Ca concentration was not significantly different between the groups, Zn concentration was lower in the PD, RA, and RAPD groups compared to the control group (p < 0.05). These groups also expressed higher MT/Zn ratios compared to the control group (p < 0.05). Unlike the control group, concentrations of inflammatory cytokines, MT, Zn, and Ca correlated with each other in the PD, RA, and RAPD groups (p < 0.05). Additionally, comorbidity of PD and RA appears to have a cumulative immuno-pathological impact that warrants further investigation. This study suggests that, in addition to inflammatory cytokines, salivary MT and Zn could reflect the severity of PD with or without RA, hence providing an important biomarker for diagnosis.

Abstract
Periodontitis is one of the most common dental diseases. Compared with healthy periodontal tissues, the immune microenvironment plays the key role in periodontitis by allowing the invasion of pathogens. It is possible that modulating the immune microenvironment can supplement traditional treatments and may even promote periodontal regeneration by using stem cells, bacteria, etc. New anti-inflammatory therapies can enhance the generation of a viable local immune microenvironment and promote cell homing and tissue formation, thereby achieving higher levels of immune regulation and tissue repair. We screened recent studies to summarize the advances of the immunomodulatory treatments for periodontitis in the aspects of drug therapy, microbial therapy, stem cell therapy, gene therapy and other therapies. In addition, we included the changes of immune cells and cytokines in the immune microenvironment of periodontitis in the section of drug therapy so as to make it clearer how the treatments took effects accordingly. In the future, more research needs to be done to improve immunotherapy methods and understand the risks and long-term efficacy of these methods in periodontitis.

Dent Res J (Isfahan) 2021; 18:79. [PMID: 34760070 PMCID: PMC8543096 DOI: 10.4103/1735-3327.326652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 01/30/2021] [Accepted: 03/17/2021] [Indexed: 11/04/2022] Open
Abstract
Background Adipocyte fatty acid binding protein (A-FABP) is a novel biomarker of inflammation for various chronic systemic diseases. Since periodontitis is a chronic inflammatory disease, this study explores the association of A-FABP with periodontal disease parameters and tumor necrosis factor-alpha (TNF-α) levels in gingival crevicular fluid in periodontal health and disease. Materials and Methods This original research article describes a cross-sectional study conducted at the Department of Periodontics, M. R. Ambedkar Dental College and Hospital, Bangalore, India. This cross-sectional investigation was conducted on sixty subjects which were divided into three groups of twenty subjects each - healthy, gingivitis, and chronic periodontitis. Clinical parameters - plaque index, bleeding index, probing depth, and clinical attachment loss were recorded. Gingival crevicular fluid samples were analyzed for A-FABP and TNF-α levels using ELISA. One-way analysis of variance was used to find the significance of study parameters on a continuous scale between three groups. Pearson's correlation has been used to find the relationship between Gingival crevicular fluid concentration of markers and periodontal parameters. Multiple linear regression analysis was applied to the study. The statistical significance was considered at P < 0.05. Results Mean concentration of A-FABP (6.43 ± 2.51) and TNF-α (3454.82 ± 1566.44) was highest in the periodontitis group, and the difference among the groups was statistically significant (P < 0.05). A positive correlation was observed between clinical attachment loss and the two markers among all groups. The correlation between A-FABP and TNF-α in periodontitis groups was positive and statistically significant (P < 0.05). Multiple linear regression model was statistically significant (P < 0.05) indicating that there is a significant relationship between the set of predictors and the clinical attachment loss. Conclusion A-FABP and TNF-α levels in GCF were significantly elevated in the presence of inflammation. A-FABP has a probable stimulatory effect on TNF-α; however, its role needs to be explored. A-FABP could serve as a novel inflammatory biomarker of periodontitis and the scope of using A-FABP inhibition as a treatment modality could be investigated with interventional studies.

Abstract
Periodontitis is an inflammatory disease caused by host immune response, resulting in a loss of periodontium and alveolar bone. Immune cells, such as T cells and macrophages, play a critical role in the periodontitis onset. Halofuginone, a natural quinazolinone alkaloid, has been shown to possess anti-fibrosis, anti-cancer, and immunomodulatory properties. However, the effect of halofuginone on periodontitis has never been reported. In this study, a ligature-induced mice model of periodontitis was applied to investigate the potential beneficial effect of halofuginone on periodontitis. We demonstrated that the administration of halofuginone significantly reduced the expression levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α) in vivo, and markedly suppressed immune cell infiltration into the infected sites. Furthermore, we also observed that halofuginone treatment blocked the T-helper 17 (Th17) cell differentiation in vivo and in vitro. We demonstrated for the first time that halofuginone alleviated the onset of periodontitis through reducing immune responses.

Abstract
OBJECTIVE The ratio between molecules which acts towards the diseased or healthy phenotype determine whether the periodontitis lesions will progress or stabilize. Considering gingival tissue and biofluids, we aimed to present a systematic review (qualitative analysis) on the ratios between disease/health periodontitis modulators, and a meta-analysis (quantitative analysis) of their levels in individuals with periodontitis compared to controls. DESIGN Electronic searches of the PubMed, Scopus, EMBASE and Web of Science databases were conducted for publications up to May 2020. RESULTS A total of 53 publications were included in the systematic review, being 22 of them focusing on the ratios between Interleukin [IL]-1/IL-10, IL-6/IL-10, IL-1/IL-1RA and RANKL/OPG. Twenty-one publications were eligible for meta-analyses. The ratios of IL-1, IL-6 and RANKL mRNA levels were significantly higher in diseased gingival tissue, as well as their protein levels in gingival crevicular fluid (GCF) of periodontitis individuals. Considering the saliva levels, the RANKL/OPG ratio was higher in periodontitis subjects in comparison to controls. Meta-analyses showed higher IL-1β, IL-1α, IL-6 and IL-10 gene expressions in gingival tissue and protein levels in GCF, while RANKL was higher in GCF of periodontitis individuals in comparison to controls. CONCLUSIONS Both the ratios and meta-analyses showed higher levels of modulators in gingival tissue and GCF of diseased individuals.

Abstract
Objective We studied cytokines in gingival crevicular fluid (GCF) in a cross‐sectional population‐based cohort of rheumatoid arthritis (RA) patients ≥61 years of age with and without a diagnosis of periodontitis. Background data Earlier studies on cytokines in GCF in RA patients have not given clear results. Methods In a population‐based cross‐sectional study of patients ≥61 years of age, 233 RA patients were identified. 132 (57%) dentate RA patients participated. All participants received rheumatological and dental examinations, and had a panoramic radiograph taken. GCF was sampled on each patient. Interleukins 1‐β (IL‐1β), IL‐4, IL‐6, IL‐10, IL‐17A, tumor necrosis factor alpha (TNF‐α), interferon gamma (IFN‐γ), and chemokines RANTES/CCL5, eotaxin and monocyte chemoattractant protein (MCP‐1) were analyzed in GCF. These cytokines were stratified for periodontitis, age, gender, body mass index (BMI), smoking, and anti‐cyclic citrullinated protein (anti‐CCP) status. Binary logistic regression analyses with periodontitis as outcome were performed adjusting for the above mentioned confounding factors including anti‐rheumatic medication, disease duration and the cytokine in question. Results Periodontitis was diagnosed in 80/132 (61%) of study participants. The 110 RA patients not participating were older, had a higher mean erythrocyte sedimentation rate (ESR), had a higher mean DAS28ESR (Disease Activity Score 28 using ESR) and were less often on biologic treatment. Only RANTES was associated with periodontitis (p = .049, OR 1.001, 95% CI 1.000–1.002) in the binary logistic regression analyses. Conclusion In this population‐based elderly RA cohort, neither pro‐inflammatory nor anti‐inflammatory cytokines in GCF were clearly associated with a diagnosis of periodontitis.

Abstract
In saliva and gingival crevicular fluid (GCF) soluble factors such as cytokines, chemokines and growth factors have shown a great potential serving as biomarkers for early detection and/or diagnosis of oral and systemic diseases. However, GCF and saliva, which one is a better source is still under debate. This study aimed to gain an overview of cytokines, chemokines and growth factors in saliva and GCF to pave the way for selecting suitable oral fluids for oral and systemic diseases. Multiplex cytokine assay was conducted to determine concentrations of cytokines, chemokines and growth factors in saliva and GCF samples from healthy subjects. The protocol for sample collection was carefully optimized. Stabilization, repeatability, and donor variation of the profiles were analyzed. We found that for different donors, cytokine and chemokine profiles showed unique patterns in saliva but similar patterns in GCF. In terms of growth factors, the profiles were individualized in saliva and GCF. All profiles stayed stable for the same healthy individual. In saliva, profiles of cytokines, chemokines and growth factors are individualized for different donors. In GCF, profiles of cytokines and chemokines are similar. Other factors, such as growth factors and T helper-related cytokines, are highly variable in donors. Profiles of soluble factors are not correlated in saliva and GCF. The comprehensive cytokine profiles in saliva and GCF reported in this work would serve as a good base for choosing promising cytokines for developing biomarkers in oral fluids.

Abstract
Periodontitis, initiated by the subgingival biofilm and modified by the individual’s inflammatory/immune response, has been associated with vascular dysfunction. To analyze microcirculation indices in periodontal tissues and determine the activity of the enzymatic component of antioxidant defense and humoral immunity factors, a single-blind non-invasive clinical trial was realized. Forty subjects, aged from 30 to 65 years, with moderate to severe chronic periodontitis (chronic generalized periodontitis, CGP) vs. 40 subjects as periodontally healthy were recruited. Information such as capillary diameter, capillary blood flow velocity, concentration of pro- and anti-inflammatory cytokines in serum, vascular endothelial growth factor, and enzymatic component of antioxidant protection were taken. The revealed microcirculatory dysfunctions in patients with CGP clearly demonstrate the progressive disorder of periodontal tissue perfusion and oxygenation, the presence of increased vascular permeability and functional failure of the microvascular system in the lesion. Cytokine profile of CGP patients’ blood serum demonstrated a significant increase of interleukin (IL)-1β, IL-6, tumor necrosis factor α (TNF-α), IL-4 levels as well as statistically significant decrease of IL-1ra, IL-10 concentration. Participants with CGP demonstrated a dominant superiority of IgM and IgG levels. In conclusion, these results contribute to a better understanding of potential correlation between microvascular changes and local and systemic markers of inflammation.

Abstract
Purpose: Acupuncture treatment of rheumatoid arthritis (RA) has a long history and has been widely recognized in the medical community. However, its mechanism of action still is rarely uncovered. In the present study, the effects of acupuncture on the immune function and MAPK pathway in synovial tissue of rats with RA were investigated; it aimed to explore the effect and mechanism of acupuncture on alleviating RA. Methods: Rats were randomly divided into control, model and acupuncture groups, 15 rats each group, and RA rat model was induced via bovine type II collagen in complete Freund’s adjuvant. The acupuncture group received "Zusanli" and "Shenshu" warm acupuncture treatment on the first day after modeling, acupuncture stimulation once a day for 21 days. The rat weight and degree of joint swelling were recorded and calculated. The ankle joint histopathology was observed by H&E staining. Serum inflammatory cytokines were detected using ELISA. An automatic biochemical analyzer was used to test serum IgG, IgM and IgA levels. Transcription factors T-bet, GATA3, RORγT, Foxp3 mRNA were monitored through RT-qPCR technology. Further, the expression of key targets of MAPK signal or phosphorylation in synovial tissue were determined using Western blotting. Results: Acupuncture relieved the joint swelling and weight loss of RA rats, ameliorated the pathological damage of the ankle joint, significantly increased the serum IgG, IgM, IgA and T-bet, and Foxp3 levels, and reduced the levels of IL-1β, IL-6, TNF-α, GATA3, and RORγT; down-regulated synovial tissue p-p38MAPK, p-JNK, and p-ERK1/2 levels and protein phosphorylation ratio (P<0.05). Conclusion: Acupuncture stimulation can improve the joint damage and promote the immune function of RA rats, possibly via blocking the expression of MAPK pathway in synovial tissue. This study provides a scientific and promising reference for acupuncture further in the clinical strategy of RA.

Abstract
This preliminary study investigates the differences between experimental periodontitis and periimplantitis in a dog model, with a focus on the histopathology, the inflammatory responses and specific immunoregulatory activities, driven by Th1/Th2 positive cells. Twelve dental implants were inserted into the edentulated posterior mandibles of six Beagle dogs and were given twelve weeks time for osseointegration. Experimental periimplantitis and periodontitis (first mandible molar) was then induced using cotton-floss ligatures. Twelve weeks later, alveolar bones were quantitated by cone beam-computer tomography. Histopathological analysis of the inflamed gingiva and of the periodontal tissues was performed by light microscopy, and the Th1/ Th2 cell populations were investigated by flow cytometry. Periimplantitis as well as periodontitis were both found to be associated with pronounced bone resorption effects, both to a similar degree vertically, but with a differential bone resorption pattern mesio-distally, and with a significantly higher and consistent bone resorption result in periimplantitis; however, with a higher variance of bone resorption in periodontitis. The histological appearances of the inflammatory tissues were identical. The percentages of Th1/ Th2 cells in the inflamed gingival tissues of both experimental periimplantitis and periodontitis were also found to be similar. Experimental periodontitis and periimplantitis in the dog model show essentially the same cellular pathology of inflammation. However, bone resorption was found to be significantly higher in periimplantitis; the histopathological changes in the periodontal tissues were similar in both groups, but showed a higher inter-individual variation in periodontitis, and appeared more uniform in periimplantitis. This preliminary study indicates that more focused experimental in-vivo inflammation models need to be developed to better simulate the human pathology in the two different diseases, and in order to have a valuable tool to investigate more specifically how novel treatments/prevention approaches may heal the differential adverse effects on bone tissue and on periodontium in periodontitis and in periimplantitis.

Abstract
Severe congenital neutropenia (SCN) is a primary immunodeficiency characterized by defect in neutrophil count. Increased risk of infections in addition to periodontal problems, such as ulcerations of oral mucosa, gingival inflammation, and rapid loss of attachment are common in the course of the disease. The aim of the present study is to define the causal relationship between the severity of periodontal inflammation and severe congenital neutropenia through identification of cytokine profile in gingival crevicular fluid (GCF). A case-control study was performed in patients diagnosed with SCN and healthy controls. Demographic data, the molecular defect, laboratory work-up were gathered from the hospital registry. Periodontal indices were recorded and GCF samples were analyzed using multiplex analysis for the simultaneous measurements of the particular cytokines and chemokines. The present study included 14 patients and 22 control subjects. Both groups were comparable in terms of age and sex. Severity of gingival inflammation measured by the criteria of Löe was higher in the SCN cases (p < 0.05). Moreover, GCF levels of IFN-α, TNF-α, IL-10, IL-13, IL-15, IL-17, IL-2, IL-7, IL-33, IP-10, MIG, MIP-1β were significantly higher in the controls. Decreased cytokine secretion seems to correlate with the decrease in neutrophil counts. The severity of gingival inflammation in SCN patients may be due to the bacterial overgrowth and the change in the content of the oral flora due to the decreased neutrophil counts. Therefore, regular periodontal examinations, the motivation of oral hygiene as well as the compliance with therapy in SCN patients contribute to the periodontal health.

Abstract
Periodontitis is a chronic inflammatory disease with a complex underlying immunopathology. Cytokines, as molecular mediators of inflammation, play a role in all stages of disease progression. T helper 17 (Th17) cells are thought to play a role in periodontitis. Th17 cell development and maintenance requires a pro-inflammatory cytokine milieu, with many of the cytokines implicated in the pathogenesis of periodontitis. Serum and saliva are easily accessible biofluids which can represent the systemic and local environment to promote the development of Th17 cells. Here we review human clinical studies that investigate IL-1β, IL-4, IL-6, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, IFN-γ, sCD40L and TNF-α in serum and saliva in periodontitis. We highlight their putative role in the pathogenesis of periodontitis and place them within a wider context of animal and other clinical studies.

Abstract
Periodontitis and rheumatoid arthritis (RA) are inflammatory diseases characterized by chronic inflammation and bone erosion. Electroacupuncture (EA) shows anti-inflammatory and anti-resorptive effects in experimental periodontitis (EP) and in RA. It is important to investigate whether EA shows these effects in periodontal tissues in the presence of these two inflammatory diseases or not. For this, Wistar rats were divided into six groups: control (C); experimental rheumatoid arthritis (RA; bovine type II collagen-induced (CII)); experimental periodontitis (EP); RA/EP (RA + EP); EP/EA (EP treated with EA); RA/EP/EA (RA + EP treated with EA). EP was induced 21 days after RA induction and EA was performed previously and during the EP induction period, every 3 days until the 36th experimental day. The rats were euthanized on day 39. RA was evaluated by edema and the withdrawal threshold of hind paws. The maxillae were removed, and alveolar bone loss (ABL) and bone radiographic density (BRD) were evaluated. Immunohistochemical analyses for interleukins (IL)-6 and -17 and nuclear factor (NF)-κB were performed. Our results showed that EA reduced only the pain intensity in arthritic rats. Histomorphometric, macroscopic, and radiographic analyses did not show differences between the control and EP/EA groups. EA caused a reduction in ABL and BRD only in the presence of EP. EA caused a reduction in IL-6 and -17 in all groups, but NF-κB was only reduced in the arthritic rats with EP. In conclusion, EA reduced the inflammation related to periodontitis in arthritic rats but did not prevent ABL.

Abstract
OBJECTIVE To analyse the citrulline level in the periodontium in association with the presence of or antibody levels against Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis. DESIGN Gingival crevicular fluid (GCF), subgingival biofilm and blood serum were sampled from 98 subjects (26 with RA, 72 without RA (NoRA)). GCF was analyzed for the level of citrulline, for interleukin (IL)-1β, IL-17, IL-10 and monocyte-chemoattractant protein (MCP)-1. Microorganisms were identified in subgingival biofilms. Antibodies againstP. gingivalis, and Aggregatibacter actinomycetemcomitans were quantified in serum. RESULTS GCF citrulline level was the lowest (by trend) in NoRA group without periodontitis. In NoRA, but not in RA an association between GCF citrulline level and P. gingivalis antibody levels was found and the GCF citrulline levels were higher in P. gingivalis positive samples. Any association of A. actinomycetemcomitans with GCF citrulline level did not exist. A model of univariate variance analysis (p = 0.001) showed a dependence of GCF citrulline level from the number of sites with PD (probing depth) ≥5 mm (p = 0.003) and the GCF MCP-1/CCL2 level (p = 0.019). Compared with NoRA in RA the number of teeth was lower, the number of sites with PD ≥ 5 mm was less, GCF levels of interleukin-17 and MCP-1/CCL2 were higher and those of IL-10 lower. Yeasts were only cultured in 15 RA patients (p < 0.001). CONCLUSION Citrullination in periodontium might be associated with P. gingivalis supporting the potential role as a trigger in the development of RA. Pathogenesis of periodontal disease in RA patients seems to differ from that in NoRA and should be investigated further.

Abstract
The pathogenesis of periodontitis (PD) involves several molecules of the immune system that interact in a network to eliminate the periodontopathogens, yet, they contribute to periodontal tissue destruction. The different mechanisms that lead to periodontal tissue damage are not clear. Despite this, immune response genes have been related to the development of PD previously, such as those involved in inflammasomes which are multiprotein complexes and cytokines including Interleukin-1. The aim of the study was to evaluate the polymorphisms in NLRP3 inflammasome, cytokine and receptor of cytokines genes in the development of periodontitis. This case-control study was conducted in 186 patients with PD (stage II and III and grade B) and 208 controls (localized gingivitis and periodontally healthy individuals). Genotyping was performed using PCR-RFLP for the SNP rs4612666 in NLRP3 and using PCR-SSP for IL1A, IL1B, IL1R, IL1RN, IL4RA, INFG, TGFB1, TNF, IL2, IL4, IL6, and IL10. Cytokine serum levels were measured using Luminex technology. SNPStats and OpenEpi software were used to perform statistical analysis. The higher frequencies of NLRP3 T/C and IL1B -511 T/T genotypes and IL2 (+166, -330) GT haplotype were observed in patients with PD compared to controls. The SNPs in NLRP3, IL1R +1970, IL6–174, TNF -308, IL2 +166 and -330, TGFB1 +869 and +915, IL4RA +1902, IL4–1098 and -590 were associated to PD in men. In conclusion, polymorphisms in NLRP3, IL1B and IL2 genes were associated to PD susceptibility. Men carrying the NLRP3, IL1R, IL6, TNF, IL2, TGFB1, IL4RA and IL4 polymorphisms had greater susceptibility than women for developing PD.

Abstract
Introduction Rheumatoid arthritis (RA) and periodontitis share risk factors and inflammatory pathways that could be related to cytokines, such as interleukin (IL)-6, IL-8, IL-17A, and tumour necrosis factor-α (TNF-α). The aim of this study was to compare periodontal status and salivary levels of selected cytokines between patients diagnosed with RA and periodontitis. RA patients were assessed for the potential influence of anti-rheumatic therapy. Material and methods One hundred and six patients were enrolled in a cross-sectional study. Medical assessment and periodontal examination were performed in 35 patients with chronic periodontitis, in 35 patients with RA and chronic periodontitis, and in 36 controls. Unstimulated whole saliva samples were analysed for IL-6, IL-8, IL-17A, and TNF-α. Results Significant differences in biomarkers and periodontal parameters were found among groups. Study groups exhibited higher mean pocket depth (PD), number of PD > 4 mm, and mean clinical attachment loss, when compared with controls. The RA group had lower bleeding on probing index and PD, but higher values of plaque indices than the periodontitis group. Concentration of evaluated cytokines were higher in the RA and periodontitis groups, compared with controls. The periodontitis group showed also higher levels of IL-6, IL-17A, and TNF-α in comparison to RA. RA patients were treated with disease-modifying anti-rheumatic drugs (DMARDs) and glucocorticosteroids. Conclusions Salivary levels of IL-6, IL-8, IL-17A, and TNF-α can be affected by periodontitis, RA, and presumably DMARDs. DMARD therapy appears to reduce destructive and inflammatory processes in periodontal tissues because lower values of PD, BOP, and salivary levels of IL-6, IL-17A, and TNF-α were found in RA.

Abstract
OBJECTIVE This study aimed to evaluate the effect of avocado/soybean unsaponifiables (ASU) on periodontal repair in rats with induced periodontitis and arthritis. METHODOLOGY Forty-five rats were submitted to periodontitis induction by insertion of ligatures into the upper second molars, maintained for 15 days. These animals were randomly allocated to 3 groups according to the presence of induced arthritis (ART) and the application of the ASU: Control (CTR) group-healthy animals, where saline solution was administered; ART-animals with induced arthritis, where saline solution was administered; ART/ASU-animals with induced arthritis, where ASU (0.6 mg/ kg) was administered. The drugs were administered daily by gavage and the animals were euthanized after 7, 15 and 30 days of the ligature removal. Bone resorption, inflammatory infiltrate composition and marker proteins expression of the differentiation and formation of osteoclasts (RANKL and TRAP) were assessed. RESULTS The ART/ASU group presented higher bone volume than the ART group at 7 and 30 days after the ligature removal. Furthermore, the ART group presented higher quantity of inflammatory cells and expression of TRAP and RANKL than the other groups. CONCLUSION ASU administration improves the repair of periodontal tissues in an experimental periodontitis model in rats with induced arthritis.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) and periodontitis share several pathological features including bone and soft tissue destruction and high levels of circulating inflammatory proteins. Studies related to cytokines in the periodontal inflammatory exudate (gingivocrevicular fluid, GCF) of RA patients might provide insight into the association between periodontitis and RA. The aim of our study was to review the literature on cytokines in GCF of RA patients including the effect of anti-rheumatic treatment with biological disease-modifying anti-rheumatic drugs (DMARDs) and periodontal treatment on these cytokines. MATERIALS AND METHODS MedLine/PubMed searches with different combinations of keywords "rheumatoid arthritis or RA" and "crevicular fluid or GCF" until June 2019 revealed 64 articles. Ten cross-sectional observational studies and nine treatment studies fulfilled the inclusion criteria. RESULTS Rheumatoid arthritis patients have increased circulating and GCF levels of pro-inflammatory cytokines and proteins, despite anti-rheumatic treatment with biological DMARDs. Presence of periodontitis was accompanied by higher cytokine and protein levels. Treatment of periodontitis resulted in a decrease of these levels. CONCLUSION Analysis of GCF of RA patients reveals that the relationship between periodontitis and RA is bidirectional, probably caused by a non-specific inflammatory burden. Data for a specific relationship are barely present in GCF.

Abstract
Mesenchymal stem cell therapy brings hope for regenerating damaged periodontal tissues. The present study aimed to investigate the therapeutic role of local bone marrow stem cell (BMSC) injection in ligation-induced periodontitis and the underlying mechanisms. Alveolar bone lesion was induced by placing ligatures subgingivally around the bilateral maxillary second molars for 28 days. The alveolar bone lesion was confirmed by micro-CT analysis and bone histomorphometry. Allogeneic BMSC transplantation was carried out at 28 day after ligation. The survival state of the transplanted BMSC was observed by bioluminescent imaging. The implantation of the BMSC into the gingival tissues and periodontal ligament was confirmed by green fluorescent protein (GFP) immunohistochemical staining. The expression level of pro-inflammatory, tumour necrosis factor-α (TNF-α) and interleukin-1β (IL-1β), and receptor activator of nuclear factor-κ B ligand (RANKL) and osteoprotegerin (OPG) in periodontal tissues were evaluated by immunohistochemical staining and real-time PCR. Significant reverse of alveolar bone lesion was observed after BMSC transplantation. The expression of TNF-α and IL-1β was down-regulated by BMSC transplantation. The number of tartrate-resistant acid phosphatase (TRAP)-positive osteoclasts in the periodontal ligament was reduced, and the increased RANKL expression and decreased OPG expression were also reversed after BMSC transplantation. It is concluded that allogeneic BMSC local injection could inhibit the inflammation of the periodontitis tissue and promote periodontal tissue regeneration.

Abstract
Periodontitis is an inflammatory disease of dental supporting tissues (gingiva, periodontal ligament, and bone) and it has been suggested as a possible etiology for rheumatoid arthritis (RA). In this systematic review, we aim to verify if periodontitis represents a risk factor for RA. Electronic databases were consulted until March 2018 considering eligibility criteria focusing on: (P, participants) adults; (E, exposure) with periodontitis; (C, comparison) without periodontitis; and (O, outcome) development of RA. Quality assessment of studies and risk-of-bias evaluation were also performed. To undertake a quantitative analysis, the number of persons with RA and a total number of participants for the case group (with periodontitis) and control group (without periodontitis) were used to calculate the odds ratio (OR) with a 95% confidence interval (CI). A total of 3888 articles were identified, and nine studies were considered eligible. Seven of 9 articles suggested an association among diseases by the common pro-inflammatory profiles. The pooled analysis of 3 articles showed a higher RA prevalence for persons with periodontitis (n = 1177) than controls (n = 254) (OR 1.97; CI 1.68–2.31; p < 0.00001). However, considerable heterogeneity among studies was verified (I2 = 96%, p < 0.00001). Periodontitis may represent a risk factor for RA by heredity, bacterial infection, and the pro-inflammatory profile shared between both diseases. Although most of the elective studies report an association between periodontitis and RA, the quantitative analysis showed a high heterogeneity, leading to the need for further studies.

Abstract
Objectives: Aim of our study was to assess the expression of salivary Interleukin 1-beta (IL-1β) and clinical periodontal parameters in naswar users and non-users (controls). Methods: Eighty four individuals (forty-two naswar users and forty-two controls) were included in the study which was conducted between August 2017 and May 2018. Salivary IL-1β levels, plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (CAL) was assessed in all the participants. Results: PD of 4mm (p<0.05), PD of 5-6mm (p<0.05), CAL (p<0.001) and levels of salivary IL-1β (p<0.05) were significantly higher among naswar users as compared to controls while PI, BOP and number of missing teeth showed no significant difference among the two groups (p>0.05). Conclusion: Periodontal inflammatory conditions were worse and salivary IL-1β levels were elevated in naswar users as compared to controls.

Abstract
The strict link between periodontitis (PD) and rheumatoid arthritis (RA) has been widely demonstrated by several studies. PD is significantly more frequent in RA patients in comparison with healthy subjects: this prevalence is higher in individuals at the earliest stages of disease and in seropositive patients. This is probably related to the role of P. gingivalis in inducing citrullination and leading to the development of the new antigens. Despite the many studies conducted on this topic, there is very little data available concerning the possibility to use the same biomarkers to evaluate both RA and PD patients. The aim of the review is to summarize this issue. Starting from genetic factors, data from literature demonstrated the association between HLA-DRB1 alleles and PD susceptibility, similar to RA patients; moreover, SE-positive patients showed simultaneously structural damage to the wrist and periodontal sites. Contrasting results are available concerning other genetic polymorphisms. Moreover, the possible role of proinflammatory cytokines, such as TNF and IL6 and autoantibodies, specifically anticyclic citrullinated peptide antibodies, has been examined, suggesting the need to perform further studies to better define this issue.

Are There Any Common Genetic Risk Markers for Rheumatoid Arthritis and Periodontal Diseases? A Case-Control Study. Mediators Inflamm 2019; 2019:2907062. [PMID: 30890897 PMCID: PMC6390239 DOI: 10.1155/2019/2907062] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Revised: 01/14/2019] [Accepted: 01/29/2019] [Indexed: 12/15/2022] Open
Abstract
Background Several studies suggest that there is a biologically plausible connection between rheumatoid arthritis (RA) and periodontal diseases (PD). Both disorders are characterized as multifactorial diseases potentially sharing common risk factors. Based on the inflammatory nature of RA and PD, the impact of genetic variations of genes of the immune system on both diseases was studied in this study. Materials and Methods We conducted a case-control study (n = 201) comparing 101 RA patients suffering from periodontal disease of different severities (no/mild PD vs. severe PD) with 100 systemically healthy controls without RA and severe PD. The genotype, allele, and haplotype distributions of 22 SNPs of 13 pro- and anti-inflammatory cytokines were assessed applying sequence-specific PCR. Results Evaluating the impact of cytokine SNPs in RA, we identified the G allele of rs1801275 in IL4Rα (p = 0.043) and the G allele of rs361525 in TNFα (p = 0.005) as disease-associated risk factors in bivariate analyses. In multivariate analyses, these significant associations could not be proven. The A allele of rs2430561 in IFNγ was indicative for severe periodontitis among the patients with rheumatoid arthritis (p = 0.039). Investigating the impact of rs2430561 in IFNγ on comorbidity using binary logistic regression analyses, the A allele was confirmed as an independent risk factor for severe periodontal disease and RA (p = 0.024). Conclusions These results emphasize the association of genetic variations in proinflammatory cytokines (TNFα and IFNγ) and cytokine receptor (IL4Rα) and RA and periodontal diseases. In multivariate analyses, the A allele of IFNγ was proven to be a significant marker of RA and PD comorbidities. The study broadens the knowledge about disease-specific differences in genetic composition and provides an improved understanding of a possible association of both diseases.

Abstract
Periodontitis is a chronic inflammatory disease caused by the colonization of teeth by the bacterial plaque biofilm and the resultant host immune responses in adjacent periodontal tissues. Disease severity can vary dramatically between patients with periodontitis, with some subjects displaying inflammation without bony destruction (gingivitis), while others experience chronic progressive or rapidly aggressive gingival connective tissue damage and bone loss. To determine whether peripheral immune dysregulation is associated with periodontitis, we performed extensive analysis of immune cell subsets in peripheral blood from patients with chronic or aggressive periodontitis versus periodontally healthy control subjects. Peripheral blood mononuclear cells (PBMC) from patients with chronic periodontitis or aggressive periodontitis and from periodontally healthy controls were analysed by 8-10-colour flow cytometry for the frequencies of various lymphocyte subsets, including interleukin (IL)-17-, interferon (IFN)-γ-, tumour necrosis factor (TNF)-α- and IL-10-producing cells, and the frequencies and phenotype of monocytes. Cytokine levels in serum from the different groups were determined by Luminex assay. We found no significant differences in the frequencies of major immune cell populations [CD4+ T cells, CD8+ T cells, γδ T cells, CD4+ CD45RO+ CD25+ CD127low regulatory T cells (Tregs ), CD19+ B cells, CD14+ monocytes] or of cytokine-producing T cells, or in the phenotype of CD14+ monocytes in peripheral blood from these patient cohorts. Additionally, no significant differences were observed in serum levels of prototypical inflammatory cytokines. These results suggest that the local gingival inflammatory response is not reflected by obvious changes in major blood immune cell subset frequencies.

Abstract
OBJECTIVES The aim of this systematic review was to evaluate human gingival crevicular fluid (GCF) tumor necrosis factor-alpha (TNF-α) as a potential biomarker for diagnosis of periodontal disease (International prospective register of systematic reviews [PROSPERO] number: CRD42015020199). METHODS An electronic search for TNF-α in human GCF was conducted until May 17, 2018. Data from systemically healthy patients with healthy periodontium or periodontal disease were incorporated. Risk bias was assessed by Newcastle-Ottawa Scale for case-control studies and Jadad scale for clinical trials. RESULTS Twenty-six studies were included (12 case-control studies, 7 clinical trials, and 7 randomized controlled trials). Most case-control studies showed increased TNF-α concentration in GCF of patients with periodontal disease. The clinical trials and randomized controlled trials demonstrated no consistent modification of TNF-α level after periodontal intervention. CONCLUSION The present data support the use of TNF-α in GCF as a potential biomarker for diagnosis of periodontal disease but not to monitor the healing after therapy.

Abstract
Background Tumor necrosis factor-alpha (TNF-α) is indicated to play a major function in chronic inflammatory disorders. Objective To assess and compare the cytokine level (TNF-α) in the serum of chronic periodontitis (CP), rheumatoid arthritis (RA), RA with CP, and healthy volunteers. Materials and Methods This original research was carried out on 80 participants, divided into Group-I 20 RA patients, Group-II 20 CP patients, Group III 20 RA with CP (RA + CP), and Group IV 20 healthy volunteers. Clinical periodontal and rheumatological parameters were assessed in all the four groups. Blood serum samples have been collected from all individuals and investigated for levels of TNF-α by mean of enzyme-linked immunosorbent assay. Results TNF-α level were remarkably elevated in the RA+CP group (30.5±2.2) followed by RA group (17.9 ± 3.6), and CP group (11.9 ± 0.96) when compared with the controls (5.5 ± 3.3). The results showed a statistical significance of P < 0.001. Correlation was not observed on comparision of clinical periodontal parameters and Rheumatological parameters with TNF-α levels. Conclusion The outcome of this present research revealed the presence of higher levels of TNF-α in individuals with RA with CP in our samples.

Abstract
Introducción: la evidencia cientí ca sobre la Artritis Reumatoide (AR) y la Enfermedad Periodontal (EP) se ha orientado hacia la presencia del periodontopatógeno Porphyromonas gingivalis (P.g). Se ha establecido, a partir de diferentes estudios, su relación con el proceso de citrulinación y producción de anticuerpos antipéptidos citrulinados. Actualmente, hay una heterogénea evidencia cientí ca con nuevos aportes y variabilidad de hallazgos entre las dos enfermedades, pero los estudios en humanos son los que más generan interés. Objetivo: revisar evidencia cientí ca sobre estudios clínicos relacionados con la patogenicidad de la Enfermedad Periodontal y Porphyromonas gingivalis en la Artritis Reumatoide. Metodología: por medio de una búsqueda se identi caron las publicaciones realizadas con los tópicos de nidos y te- niendo en cuenta el análisis de contenido de estudios clínicos. Se revisó en el período de 2012-2016, los términos de búsqueda empleados fueron: rheumatoid arthritis y Porphyromonas gingivalis, con una lectura inicial basada en títulos y resúmenes, se excluyeron revisiones, reporte de casos, estudios in vitro y en animales. Resultados: después de realizar la búsqueda en tres bases de datos (PubMed, Lilacs y Embase), se encontraron 166 artículos, de los cuales 140 fueron rechazados y 25 fueron incluidos, pues describían estudios clínicos entre AR y P.g. La mayoría mostró una investigación de tipo cuantitativo, determinando la presencia de P.g en los pacientes con AR. Es clara la presencia de anticuerpos de P.g en suero y se ha reportado poca presencia en líquido sinovial, se ha identi cado ADN bacteriano en pacientes con AR y enfermedad periodontal. Nueva evidencia sugiere asociaciones con otros patógenos y detección en artritis de aparición temprana.

Abstract
BACKGROUND Rheumatoid arthritis (RA) and chronic periodontitis are the most common chronic inflammatory diseases with significant pathological and clinical similarities. Numerous studies have indicated a relationship between rheumatoid arthritis and periodontal disease. The aim of this study was to compare the TNF-α levels in saliva among patients with Rheumatoid arthritis (RA) and chronic periodontitis as well as healthy subjects. METHODS One hundred and seventy-one patients were enrolled in this cross-sectional study. Fifty-seven patients diagnosed of RA, 57 patients with chronic periodontitis and 57 healthy subjects. These patients have been examined with regard to TNF-α level from salivary samples. Their teeth were examined with regard to Plaque Index , Gingival Index, probing depth and clinical attachment level.All patients were non-smokers. RESULTS The results revealed a significant difference in all periodontal parameters among the three groups. The chronic periodontitis group showed a significantly higher value in all clinical periodontal parameters in comparison to both the RA and healthy groups. No significant difference was found between salivary TNF-α level among the three study groups. CONCLUSIONS Patients with chronic periodontitis had the highest periodontal indices. However there was no significant difference regarding the level of salivary TNF-α. Hence, suppression of proinflammatory cytokines might prove beneficial in suppressing periodontal diseases among RA patients.

Abstract
Focused Clinical Question: What are the key considerations for coordination of care for a patient with rheumatoid arthritis (RA) and chronic periodontitis (CP), and what are the clinical implications of RA on periodontal health? Summary: Both RA and CP involve hyper-immune response and osseous destruction. However, despite emerging evidence that RA and CP may have common etiologies and patients with RA have increased risk of CP, periodontal evaluation and treatment remain largely similar for patients with and without RA. More fully assessing inflammatory burden in patients with RA and CP may allow practitioners to more accurately assess the risk profile of a patient for RA and periodontal disease progression and to better evaluate adequate end points to periodontal therapy. Furthermore, coordination of care for patients with RA and CP with their rheumatologist or treating physician could allow for advanced screening and prophylactic care that may prevent disease development or progression. Conclusion: For patients with RA and CP, evaluation of their rheumatoid disease activity score and periodontal inflamed surface area score, rather than traditional periodontal clinical measurements, along with additional biologic sampling methods may be appropriate measures to more accurately assess inflammatory burden in these susceptible patients.

Abstract
BACKGROUND Metabolic Syndrome (MS) and chronic oral condition (periodontitis [PD]) are state of inflammation. The study was conducted to determine alterations in serum and salivary cytokines level in MS and/or chronic PD in the North Indian population. MATERIALS AND METHODS This cross-sectional study carried out in northern part of India. The study subjects of similar ethnicity were recruited according to International Diabetes Federation (IDF) criteria for MS, while chronic PD was diagnosed on the basis of packet depth and clinical attachment level. ELISA method was employed to assess cytokine level. All subjects were divided in four groups Gr A (MS + PD), B (MS), C (PD), and a control Gr D. RESULTS The serum and salivary tumor necrosis factor alpha (TNF-α) level in Gr A, B, and C was significantly higher than Gr D (P < 0.05). Serum interleukin-10 (IL-10) level in Gr A, B, and C was lower than Gr D (P < 0.05), but this difference was not significant between Gr C and Gr D. Serum IL-10 level in Gr A was significantly lower than Gr C (P < 0.05). Salivary IL-10 level was not significantly altered in any group. CONCLUSIONS Proinflammatory marker TNF-α has correlation with clinical parameters in patients of MS having PD. The study suggests level of salivary TNF-α may be utilized as a surrogate marker of MS and PD.

Abstract
OBJECTIVE To compare five biomarker levels in gingival crevicular fluid (GCF) in different tooth-sites of subjects with healthy periodontium, aggressive periodontitis and severe chronic periodontitis, and to evaluate the value of these biomarker levels for diagnosis of the type and activity of periodontitis. MATERIALS AND METHODS Prior to therapy, GCF samples were collected using filter paper strip at different tooth-sites of 10 subjects with healthy periodontium (H), 15 with severe chronic periodontitis (CP) and 15 with aggressive periodontitis (AgP). The strips were weighed and the periodontal clinical parameters were recorded. Levels of interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), and alkaline phosphatase (ALP) in GCF were assessed by enzyme-linked immunosorbent assay (ELISA). RESULTS The volumes of the GCF samples obtained in CP and AgP subjects were significantly higher than those from subjects with healthy periodontium (P<0.05). Levels of IL-6, TNF-α, CRP and ALP were significantly higher in the untreated disease sites in the CP and AgP groups compared to those in control sites in the H group, while IL-10 levels were lower in the CP and AgP groups than those in the control sites in the H group. However, the levels of all five biomarker levels showed significant correlation with the clinical parameters. CONCLUSION The measurement of five biomarker levels in GCF may facilitate overall screening of periodontitis patients in epidemiological studies and allow estimation of periodontitis activity.

Abstract
Microenvironmental conditions can interfere with the functional role and differentiation of mesenchymal stem cells (MSCs). Recent studies suggest that an inflammatory microenvironment can significantly impact the osteogenic potential of periodontal ligament stem cells (PDLSCs), but the precise effects and mechanisms involved remain unclear. Here, we show for the first time that interleukin-1β (IL-1β) has dual roles in the osteogenesis of PDLSCs at concentrations ranging from physiologically healthy levels to those found in chronic periodontitis. Low doses of IL-1β activate the BMP/Smad signaling pathway to promote the osteogenesis of PDLSCs, but higher doses of IL-1β inhibit BMP/Smad signaling through the activation of nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling, inhibiting osteogenesis. These results demonstrate that crosstalk between NF-κB, MAPK and BMP/Smad signaling mediates this dual effect of IL-1β on PDLSCs. We also show that the impaired osteogenesis of PDLSCs results in more inflammatory cytokines and chemokines being released, inducing the chemotaxis of macrophages, which further clarifies the role of PDLSCs in the pathogenesis of periodontitis.

Abstract
AIMS To compare gingival crevicular fluid (GCF) cytokines/chemokines levels between periodontally healthy subjects and subjects diagnosed with chronic periodontitis (ChP), before and after non-surgical periodontal treatment, and to establish their predictive value for periodontal disease progression. METHODS Studies indexed in MEDLINE and EMBASE published in English, Portuguese and Spanish were eligible for this review. Database searches up to December 2015, and manual search of the reference list from reviews and selected articles was performed. Only studies providing data on GCF cytokines/chemokines levels in subjects diagnosed with ChP and periodontally healthy controls were included. Cross-sectional, case series, single-arm clinical studies, randomized controlled trials and prospective/retrospective cohort studies were included. Meta-analyses were conducted for those cytokines/chemokines with at least three available studies. RESULTS GCF levels of IL-1β, IL-6, IFN-γ and MCP-1/CCL2 were significantly higher in subjects diagnosed with ChP than periodontally healthy subjects. A significant decrease in GCF levels of IL-1β and IL-17 was observed after non-surgical periodontal treatment, whereas a significant increase was observed for IL-4. CONCLUSION Evidence for significant differences between periodontal health and ChP was observed for a few cytokines and one chemokine. No conclusions could be drawn with regards to increased risk of disease progression.

[PMID: 26347200 PMCID: PMC4539505 DOI: 10.1155/2015/259074] [Citation(s) in RCA: 90] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2015] [Revised: 06/08/2015] [Accepted: 06/24/2015] [Indexed: 12/12/2022] Open
Abstract
Periodontitis (PD) and rheumatoid arthritis (RA) are immunoinflammatory diseases where leukocyte infiltration and inflammatory mediators induce alveolar bone loss, synovitis, and joint destruction, respectively. Thus, we reviewed the relationship between both diseases considering epidemiological aspects, mechanical periodontal treatment, inflammatory mediators, oral microbiota, and antibodies, using the keywords “periodontitis” and “rheumatoid arthritis” in PubMed database between January 2012 and March 2015, resulting in 162 articles. After critical reading based on titles and abstracts and following the inclusion and exclusion criteria, 26 articles were included. In the articles, women over 40 years old, smokers and nonsmokers, mainly constituted the analyzed groups. Eight studies broached the epidemiological relationship with PD and RA. Four trials demonstrated that the periodontal treatment influenced the severity of RA and periodontal clinical parameters. Nine studies were related with bacteria influence in the pathogenesis of RA and the presence of citrullinated proteins, autoantibodies, or rheumatoid factor in patients with PD and RA. Five studies investigated the presence of mediators of inflammation in PD and RA. In summary, the majority of the articles have confirmed that there is a correlation between PD and RA, since both disorders have characteristics in common and result from an imbalance in the immunoinflammatory response.

Abstract
Periodontitis is a highly prevalent infectious disease characterized by the progressive inflammatory destruction of tooth-supporting structures, leading to tooth loss. The underling molecular mechanisms of the disease are incompletely understood, precluding the development of more efficient screening, diagnostic and therapeutic approaches. We investigated the interrelation of three known effector mechanisms of the cellular response to periodontal infection, namely reactive oxygen species (ROS), matrix metalloproteinases (MMPs) and cytokines in primary cell cultures of human periodontal ligament fibroblast (hPDLF). We demonstrated that ROS increase the activity/levels of gelatinolytic MMPs, and stimulate cytokine secretion in hPDLF. Additionally, we proved that MMPs possesses immune modulatory capacity, regulating the secreted levels of cytokines in ROS-stimulated hPDLF cultures. This evidence provides further insight in the molecular pathogenesis of periodontitis, contributing to the future development of more effective therapies.

Abstract
Periodontitis or Periodontal disease (PD) and Rheumatoid arthritis (RA) are two the most common chronic inflammatory diseases. Periodontitis is a biofilm associated destructive inflammatory disease of the periodontium caused by specific microorganisms. Rheumatoid arthritis is an autoimmune condition and is identified by elevated serum autoantibody titre directed against citrullinated peptides or rheumatoid factor. Periodontitis may involve some elements of autoimmunity. Recent studies have established that PD and RA show a common pathway and could be closely associated through a common dysregulation and dysfunction in inflammatory mechanism. The enzyme peptidyl arginine deiminase (PAD), expressed by Porphyromonas gingivalis (P. gingivalis) is responsible for the enzymatic deimination of arginine residuals to citrulline resulting in protein citrullination and its increased accumulation in RA. Citrullination by PAD may act as a putative biologic link between PD and RA. Association of Human leukocytic antigen-DR4 antigen has been established both with RA and PD. Several interleukins and inflammatory mediators (ILs) and Nuclear factor kappa beta ligand are linked to these common chronic inflammatory diseases. Antibodies directed against heat shock protein (hsp 70 ab) of P. gingivalis, P. melanogenicus and P. intermedia are raised in PD as well as RA. Both the conditions share many pathological and immunological similarities. Bacterial infection, genetic susceptibility, altered immune reaction and inflammatory mediators considered responsible for RA are also associated with PD. So it is plausible that a biological link may exist between PD and RA. Therapies aimed at modifying the expression and effect of inflammatory mediators and effector molecules such as matrix metalloproteinases, proinflammatory cytokines and autoantibodies of structural proteins may probably reduce the severity of both RA and PD.

Abstract
AIM It is hypothesized that self-perceived oral health and periodontal status are worse in chronic periodontitis (CP) patients with rheumatoid arthritis (RA) compared to CP patients without RA. The aim of the present study was to assess self-perceived oral health and periodontal parameters in CP patients with and without RA. METHODS Fifty CP patients with RA and 50 CP patients without RA were included. Information regarding sociodemographic characteristics and self-perceived oral symptoms were collected using a questionnaire. Periodontal parameters (plaque index, bleeding on probing, probing depth, clinical attachment loss, number of missing teeth, and marginal bone loss) were recorded. RESULTS There was no significant difference in socioeconomic status, education status, self-perceived oral symptoms, and periodontal parameters among CP patients with and without RA. CONCLUSIONS Self-perceived oral health and periodontal parameters are mainly governed by the intensity of CP, and the role of RA in this context seems to be rather secondary.
