Yakar N, Emingil G, Türedi A, Şahin Ç, Köse T, Bostanci N, Silbereisen A. Value of gingival crevicular fluid TREM-1, PGLYRP1, and IL-1β levels during menopause. J Periodontal Res 2023; 58:1052-1060. [PMID: 37529985 DOI: 10.1111/jre.13167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 06/06/2023] [Accepted: 07/20/2023] [Indexed: 08/03/2023]
Abstract
OBJECTIVE This study aimed to investigate the association of GCF TREM-1, PGLYRP1, and IL-1β levels with periodontal health in pre- and postmenopausal women. BACKGROUND Triggering receptor expressed on myeloid cells 1 (TREM-1), activated through its ligand peptidoglycan recognition protein 1 (PGLYRP1), stimulates proinflammatory cytokine production, such as interleukin (IL)-1β, during periodontal inflammation. Postmenopausal changes may modulate these immune-inflammatory functions. No clinical study has yet investigated the effect of menopause on TREM-1, PGLYRP1, and IL-1β levels in gingival crevicular fluid (GCF). METHODS This cross-sectional study included 148 women (age range = 35-65 years), divided into postmenopausal women (PMW) (n = 76, mean age = 54 ± 5 years) and regularly menstruating premenopausal women (RMPW) (n = 72, mean age = 40 ± 4 years). Clinical periodontal parameters were recorded. TREM-1, PGLYRP1, and IL-1β levels were quantified with enzyme-linked immunosorbent assays. Pearson's Chi-squared test and Mann-Whitney-U test were used to compare categorical and numerical variables, respectively. Spearman's Rho correlation analysis was used to test the linear relationship between variables. Analyte level data were categorized based on the periodontal diagnosis and menopause status (2 × 2 nonparametric factorial ANOVA). RESULTS No significant differences in TREM-1, PGLYRP1, and IL-1β levels between PMW and RMPW were observed (p > .05). Mean values of periodontal indexes including probing depth did not differ significantly between PMW and RMPW groups (p = .474). TREM-1 levels were significantly higher in both PMW and RMPW with periodontitis, compared to gingivitis or health (p = .0021). CONCLUSION Menopause-related changes have no observable effect on GCF levels of TREM-1, PGLYRP1, and IL-1β. Higher GCF TREM-1 levels in women with periodontitis regardless of their menopausal status indicate that TREM-1 may be an indicator for periodontitis both in premenopausal and postmenopausal women.

Assessment of Cardiovascular Risk in Women with Periodontal Diseases According to C-reactive Protein Levels. Biomolecules 2021; 11:biom11081238. [PMID: 34439905 PMCID: PMC8394419 DOI: 10.3390/biom11081238] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 08/06/2021] [Accepted: 08/16/2021] [Indexed: 12/25/2022] Open
Abstract
Cardiovascular diseases (CVD) are highly prevalent non-communicable diseases worldwide. Periodontitis may act as a non-traditional cardiovascular risk (CVR) factor, linked by a low-grade systemic inflammation mediated by C-reactive protein (CRP). Patients with periodontitis reported higher serum CRP levels; however, a CRP systemic and periodontal correlation in gingival crevicular fluid (GCF) and its CVR impact have been barely studied. We aimed to assess the association between periodontal diseases and CVR in a group of adult women, based on serum high-sensitivity CRP (hs-CRP) levels; and secondly, to determine the association between serum and GCF CRP levels. Gingival crevicular fluid and blood samples were obtained from women with periodontitis, gingivitis, and healthy controls. Serum and GCF CRP were determined by turbidimetric method and Luminex technology, respectively. Data were analyzed and adjusted by CVR factors. All women presented moderate CVR, without an evident association between serum hs-CRP levels and periodontal diseases. While serum hs-CRP concentrations did not significantly differ between groups, patients with gingivitis and periodontitis showed higher CRP levels in GCF, which positively correlated to CRP detection in serum.

Abstract
Objectives
This study aimed to examine the impact of hyperbaric oxygen therapy (HBOT) on serum C-reactive protein (CRP) levels, osteoclast numbers, and osteoprotegerin (OPG) expression in periodontitis-induced diabetic rats
Materials and Methods
This study constituted an
in vivo
laboratory-based experiment incorporating a posttest only control group design. Thirty male Wistar rats were divided into three groups of research subjects: a healthy group (K0), periodontitis-induced diabetic group (K1), and periodontitis-induced diabetic group treated with HBOT for 7 days (K2). After treatment, the subjects were sacrificed to determine the level of serum CRP by the ELISA method. Immunohistochemical analysis was conducted to check the level of OPG expression, while a histological analysis was undertaken to quantify the number of osteoclasts.
Statistical Analysis
The data was analyzed using a one-way ANOVA and Least Significant Difference (LSD) test on which a result of
p
< 0.05 was considered statistically significant.
Results
HBOT appreciably decreased serum CRP levels, significantly enhancing OPG expression in periodontitis-induced diabetic (
p
< 0.05) and decreasing the number of osteoclasts in -periodontitis-induced diabetic (
p
> 0.05).
Conclusion
HBOT reduced the serum CRP level, increased OPG expression, and decreased osteoclast numbers in periodontitis-induced diabetic rats.

Abstract
The periodontium undergoes age-related cellular and clinical changes, but the involved genes are not yet known. Here, we investigated age-related genetic changes in gingiva at the transcriptomic level. Genes that were differentially expressed between young and old human gingiva were identified by RNA sequencing and verified by real-time PCR. A total of 1939 mRNA transcripts showed significantly differential expression between young and old gingival tissues. Matrix metalloprotease (MMP) regulation was the top pathway involved in gingival aging. MMP3, MMP9, MMP12, and MMP13 were upregulated in old gingival tissues, concomitantly with interleukin-1 beta (IL1B) expression. In vitro experiments using human gingival fibroblasts (hGFs) showed that MMP12 was upregulated in old hGFs compared to young hGFs. Moreover, the MMP3, MMP9 and IL1B levels were more highly stimulated by infection with the oral bacterium, Fusobacterium nucleatum, in old hGFs compared to young hGFs. Collectively, these findings suggest that, in gingiva, the upregulation of MMP12 may be a molecular hallmark of natural aging, while the upregulations of MMP3, MMM9, and IL1B may indicate externally (e.g., infection)-induced aging. These findings contribute to our understanding of the molecular targets involved in gingival aging.

Abstract
AIM Increased C-reactive protein levels have been found in all active inflammations, including periodontitis. This study aims to assess the C-reactive protein levels in periodontal disease progression. METHODS Forty-five patients were divided into the following three groups (n=15) based on gingival index, probing pocket depth, and clinical attachment level: healthy (group I), gingivitis (group II), and chronic periodontitis (group III). Gingival crevicular fluid and serum samples were quantified for C-reactive protein using enzyme-linked immunosorbent assay. RESULTS The mean C-reactive protein concentration in gingival crevicular fluid and serum was found to be highest in group III (1233.33ng/mL for gingival crevicular fluid, 5483.33ng/mL for serum), and least in group I (60 ng/mL and 413 ng/mL for gingival crevicular fluid and serum, respectively) The mean C-reactive protein concentration in group II (453.33ng/mL for gingival crevicular fluid and 3565.33 ng/mL for serum) was found to be intermediate. CONCLUSIONS C-reactive protein levels in gingival crevicular fluid and serum increased proportionately with the severity of periodontal disease. They correlated positively with clinical parameters, including gingival index, probing pocket depth, and clinical attachment level. Thus, it can be considered as a periodontal inflammatory biomarker and deserves further consideration.

Abstract
Reactional episodes in leprosy are a result of complex interactions between the immune system, Mycobacterium leprae, and predisposing factors, including dental infections. To determine the main inflammatory mediators in the immunopathological process of dental infections and leprosy reactions, we conducted a systematic review of primary literature published between 1996 and 2013. A three-stage literature search was performed (Stage I, "leprosy reactions" and "inflammatory mediators"; Stage II, "dental infections" and "inflammatory mediators"; and Stage III, "leprosy reactions," "dental infections," and "inflammatory mediators"). Of the 911 eligible publications, 10 were selected in Stage I, 68 in Stage II, and 1 in Stage III. Of the 27 studied inflammatory mediators, the main proinflammatory mediators were IL-6, IFN-γ, TNF-α, IL-1β, and IL-17; the main anti-inflammatory mediators were IL-10 and IL-4. Serum IL-6 and TNF-α concentrations were significant during periodontal and reactional lesion evolution; IFN-γ and IL-1β were associated with types 1 and 2 reactions and chronic periodontal disease. The proinflammatory mediators in dental infections and leprosy reactions, especially IL-6 and TNF-α, were similar across studies, regardless of the laboratory technique and sample type. IFN-γ and IL-1β were significant for leprosy reactions and periodontal diseases. This pattern was maintained in serum.

Abstract
OBJECTIVE Gingival fibroblasts (GFs) are an important regulatory cell type in the progression of periodontitis. This study aimed to compare the expression levels of genes associated with inflammation, extracellular matrix degradation and bone destruction in GFs isolated from healthy and periodontitis subjects in the absence and presence of Porphyromonas gingivalis. DESIGNS Primary GFs from healthy (n=10) and periodontitis subjects (n=10) were stimulated in vitro with viable P. gingivalis ATCC 49417 and 3 clinical isolates of P. gingivalis with type II fimbriae from one healthy subject (KUMC-H1) and two periodontitis patients (KUMC-P1, -P2). The mRNA expression of proinflammatory cytokines (interleukin (IL)-6, IL-8, IL-1B), anti-inflammatory cytokines (IL-4, IL-10), matrix metalloproteinase (MMP)-1 and 2, tissue inhibitor matrix metalloproteinase (TIMP)-3 and osteoprotegerin (OPG) were assessed using real-time PCR. The levels of IL-6, IL-1β and TIMP-3 protein were measured by an enzyme-linked immunosorbent assay. RESULTS The mRNA expression of IL-6, IL-1B and TIMP-3 was higher in the periodontitis group compared with the healthy group, whereas IL-4 expression was higher in the healthy group both in the absence and presence of the P. gingivalis strains. The expression levels of IL-6, IL-1β and TIMP-3 protein were also higher in the periodontitis group in the absence and/or presence of the P. gingivalis strains. There was inter-strain variability among P. gingivalis strains in the ability to induce expression of the proinflammatory cytokines, MMPs and OPG and in the ability to degrade IL-6 protein. CONCLUSION High expression of proinflammatory cytokines and TIMP-3 and low expression of IL-4 can be a signature of GFs associated with periodontitis.

Abstract
BACKGROUND AND OBJECTIVE Gingival crevicular fluid has been suggested as a possible source of biomarkers for periodontal disease progression. This paper describes a technique for the analysis of gingival crevicular fluid from individual sites using mass spectrometry. It explores the novel use of mass spectrometry to examine the relationship between the relative amounts of proteins and peptides in gingival crevicular fluid and their relationship with clinical indices and periodontal attachment loss in periodontal maintenance patients. The aim of this paper was to assess whether the mass spectrometric analysis of gingival crevicular fluid may allow for the site-specific prediction of periodontal disease progression. MATERIAL AND METHODS Forty-one periodontal maintenance subjects were followed over 12 mo, with clinical measurements taken at baseline and every 3 mo thereafter. Gingival crevicular fluid was collected from subjects at each visit and was analysed using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. Samples were classified based upon pocket depth, modified gingival index (MGI), plaque index and attachment loss, and were analysed within these groups. A genetic algorithm was used to create a model based on pattern analysis to predict sites undergoing attachment loss. RESULTS Three hundred and eighty-five gingival crevicular fluid samples were analysed. Twenty-five sites under observation in 14 patients exhibited attachment loss of > 2 mm over the 12-mo period. The clinical indices pocket depth, MGI, plaque levels and bleeding on probing served as poor discriminators of gingival crevicular fluid mass spectra. Models generated from the gingival crevicular fluid mass spectra could predict attachment loss at a site with a high specificity (97% recognition capability and 67% cross-validation). CONCLUSIONS Gingival crevicular fluid mass spectra could be used to predict sites with attachment loss. The use of algorithm-generated models based on gingival crevicular fluid mass spectra may provide utility in the diagnosis of periodontal disease.

Abstract
BACKGROUND The aim of the present study is to investigate gingival crevicular fluid (GCF) and plasma acute-phase cytokines, interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-11 (IL-11), oncostatin M (OSM), and leukemia inhibitory factor (LIF) levels in patients with different periodontal diseases. METHODS Eighty individuals were included in this study; 20 with chronic periodontitis (CP), 20 with generalized aggressive periodontitis (GAgP), 20 with gingivitis, and 20 classified as healthy (H). Probing depth, clinical attachment level, plaque index, and papilla bleeding index were recorded. Plasma and GCF IL-1β, IL-6, IL-11, OSM, and LIF levels were analyzed by enzyme-linked immunosorbent assay. RESULTS CP and GAgP groups had significantly higher GCF IL-1β, IL-6, and IL-11 levels when compared with the H group (P <0.05). Conversely, GCF LIF levels of the CP and GAgP groups were lower than those of the H group (P <0.05). GCF OSM levels did not differ significantly among study groups. Plasma levels of all the cytokines studied were not significantly different among the study groups. CONCLUSIONS Based on the present data, elevated IL-1β, IL-6, and IL-11 GCF levels, but not plasma levels, are suggested as reliable inflammatory biomarkers in periodontal diseases. Decreased LIF levels in diseased groups might reflect the possible beneficial effects of LIF in the modulation of inflammatory response in gingiva.

Abstract
BACKGROUND AND AIM Periodontitis is associated with elevated C-reactive protein (CRP) in both serum and gingival crevicular fluid (GCF). Although the liver is the primary source of CRP, extra-hepatic production of CRP has been reported. This study aimed to determine whether CRP in GCF is produced locally in the gingivae. MATERIALS AND METHODS Gingivae and GCF were collected from non-periodontitis and periodontitis sites. Presence of CRP in gingivae was assessed by immunohistochemistry. CRP in GCF was measured using ELISA. Gene expression for CRP in gingivae was determined using real-time polymerase chain reaction. RESULTS CRP was found in both the gingivae and GCF. No gingivae had detectable amounts of CRP mRNA. Not all patients with periodontitis had detectable levels of CRP in the GCF. Some non-periodontitis patients had detectable levels of CRP in the GCF. CONCLUSION CRP in the GCF appears to be of systemic origin, and therefore may be indicative of systemic inflammation from either a periodontal infection or inflammatory disease elsewhere. The correlation between levels of CRP in GCF and serum requires validation in future studies.

Abstract
AIMS To evaluate the interleukin-1 beta (IL-1 beta) levels in gingival crevicular fluid (GCF) and serum in either naturally occurring (N-O) or experimentally induced (E-I) plaque-associated gingivitis. MATERIAL AND METHODS Thirty-seven periodontally healthy subjects were evaluated in real life conditions (N-O gingivitis) as well as after 21 days of experimental gingivitis trial (E-I gingivitis). During the experimental gingivitis trial, in one maxillary quadrant (test quadrant), gingival inflammation was induced by oral hygiene abstention, while in the contralateral (control) quadrant, oral hygiene was routinely continued. IL-1 beta concentrations in N-O and E-I gingivitis were investigated for IL-1B(+3954) and IL-1B(-511) gene polymorphisms. RESULTS (i) GCF IL-1 beta concentrations in E-I gingivitis were significantly higher compared with N-O gingivitis; (ii) an intra-individual correlation between GCF concentrations of IL-1 beta detected in N-O and E-I gingivitis was observed in control quadrants, but not in test quadrants; (iii) IL-1 beta concentration in GCF was associated with IL-1B(+3954) genotype only at test quadrants; (iv) IL-1 beta was detectable in serum only at low levels in a limited number of subjects, without difference between gingivitis conditions. CONCLUSIONS Aspects of the bacterial challenge to the gingival tissues, such as the amount of plaque deposits and plaque accumulation rate, appear to affect the IL-1 beta levels in GCF in subjects with a specific IL-1B genotype.

Abstract
AIM Metabolic syndrome consists of a cluster of clinical and biological abnormalities, influenced by insulin resistance and promoting cardiovascular diseases. We examined the relationships between metabolic syndrome, its various components, insulin resistance, and periodontitis. MATERIALS AND METHODS The study included 276 subjects (35-74 years) recruited within a cross-sectional survey on cardiovascular risk factors. Twenty-one were excluded because of infectious risk or total tooth loss. Clinical attachment loss (CAL), probing pocket depth (PD), gingival and plaque indexes were recorded. Periodontitis was classified into moderate and severe forms. RESULTS The mean age was 58, 41% of the subjects had moderate and 39% had severe periodontitis. In univariate comparisons, periodontitis was associated with metabolic syndrome (p=0.050), most of its components, and HOMA index (homoeostasis model assessment of insulin resistance). After adjustment for confounders, only HOMA index remained associated with severe periodontitis (odds ratio [OR]=3.97 [95% confidence interval: 1.22-12.9], OR=3.78 [1.14-12.5] for third and fourth versus the first quartile of the HOMA index, respectively). The HOMA index was also associated with the number of periodontal sites with CAL>or=4 mm, CAL>or=5 mm, or PD>or=4 mm (greater number for higher HOMA-index values). This relationship disappeared in never-smokers. CONCLUSIONS Our data support the relationships between metabolic disturbances and periodontitis, with a central role of insulin resistance.
