Soluble neuropilin-1 in gingival crevicular fluid is associated with rheumatoid arthritis: An exploratory case-control study. J Oral Biol Craniofac Res 2021; 11:303-307. [PMID: 33747759 PMCID: PMC7970360 DOI: 10.1016/j.jobcr.2021.02.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 01/21/2021] [Accepted: 02/17/2021] [Indexed: 10/22/2022] Open
Abstract
BACKGROUND To explore the soluble Neuropilin-1 (sNRP-1) concentrations in gingival crevicular fluid (GCF) and the periodontal clinical status of patients with Rheumatoid Arthritis (RA). MATERIALS AND METHODS We conducted an exploratory study with 40 study participants, 20 with RA, and 20 healthy controls. Clinical and periodontal data were recorded, and GCF samples were obtained. sNRP-1 levels in GCF were determined by ELISA assay. Descriptive statistics, Mann-Whitney U test, Unpaired t-test, logistic regression model, and Area Under Receiver Operating Characteristic Curve (AUC-ROC) were made to explore the diagnostic performance accuracy. RESULTS RA patients had significantly higher levels of sNRP-1 in GCF (p = 0.0447). The median levels of GCF-sNRP-1 were 208.85 pg/μl (IQR 131.03) in the RA group compared to 81.46 pg/μl (IQR 163.73) in the control group. We observed an association between the GCF-sNRP-1 concentrations and the RA diagnosis (OR:1.009; CI 1.00-1.001; p = 0.047). The diagnosis of chronic periodontitis was also associated with RA (OR: 6.9; CI 1.52-31.37; p = 0.012). Moreover, the AUC-ROC of GCF-sNRP-1 concentrations combined with periodontal clinical parameters such as periodontal probing depth and periodontal inflamed surface area was 0.80. CONCLUSION This exploratory case-control study shows that RA patients had significantly higher levels of sNRP-1 in GCF. New longitudinal studies are necessary to evaluate the role of NRP-1 in periodontal tissues and consider it an oral biomarker with clinical value in RA.

J Oral Biol Craniofac Res 2021; 11:84-87. [PMID: 33384917 PMCID: PMC7770967 DOI: 10.1016/j.jobcr.2020.11.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 11/04/2020] [Accepted: 11/21/2020] [Indexed: 10/22/2022] Open
Abstract
BACKGROUND Soluble Neuropilin-1 (sNRP-1) is a glycoprotein with angiogenic and immune regulatory functions, which correspond to processes deeply involved with periodontal diseases. This study's objective was to determine the concentration of sNRP-1 in gingival crevicular fluid (GCF) samples of severe periodontitis (stages III-IV) compared to mild-moderate (stages I-II) periodontitis patients. MATERIALS AND METHODS An exploratory cross-sectional study was conducted, including 36 adults subjected to a complete periodontal exam, which recorded the following periodontal parameters: periodontal probing depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), gingival index (GI) and periodontal inflamed surface area (PISA). Periodontitis was defined by two periodontists using the case definition proposed by the 2017 World Workshop for periodontal diseases. GCF samples were collected to determine the levels of sNRP-1 via ELISA. The results were analyzed using descriptive statistics, Mann-Whitney, Kruskal Wallis, and Spearman tests. RESULTS The levels of sNRP-1 in patient's GCF with periodontitis in stages III-IV showed a median of 38.385 ng/mL (iqr 30.98), in comparison with 20.085 ng/mL (iqr 12.74) for stages I-II (p = 0.202). Regardless of the periodontitis stage, we observed a positive correlation between the levels of sNRP-1 in BOP (Rho: 0.45; p = 0.0048), PISA (Rho: 0.50; p = 0.0019), PD (Rho: 0.3; p = 0.015) and GI (Rho: 0.37; p = 0.02). CONCLUSIONS The GCF-sNRP-1 concentration was positively related to periodontal clinical inflammatory parameters and probably could be involved in pro-inflammatory and angiogenic mechanisms observed in periodontitis. Additional studies are necessary to confirm these preliminary results.

Abstract
Commensal microbiota inhabit all the mucosal surfaces of the human body. It plays significant roles during homeostatic conditions, and perturbations in numbers and/or products are associated with several pathological disorders. Angiogenesis, the process of new vessel formation, promotes embryonic development and critically modulates several biological processes during adulthood. Indeed, deregulated angiogenesis can induce or augment several pathological conditions. Accumulating evidence has implicated the angiogenic process in various microbiota-associated human diseases. Herein, we critically review diseases that are regulated by microbiota and are affected by angiogenesis, aiming to provide a broad understanding of how angiogenesis is involved and how microbiota regulate angiogenesis in microbiota-associated human conditions.

Abstract
Angiogenesis is an important phenomenon in the pathogenesis of some diseases, such as numerous types of tumors and autoimmunity, and also a number of soluble and cell-bound factors may stimulate neovascularization in inflammatory reaction processes. Here, by highlighting the significance of angiogenesis reaction in rheumatoid arthritis (RA), we will mainly focus on the role of various growth factors, cytokines, enzymes, cells, hypoxic conditions and transcription factors in the angiogenic process and we will then explain some therapeutic strategies based on blockage of angiogenesis and modification of the vascular pathology in RA.

Abstract
BACKGROUND Angiogenic factors are involved in the physiopathology of several inflammatory diseases and they probably play a role in the pathogenesis of acute pancreatitis (AP). AIMS To investigate if angiogenic factors are elevated in patients with AP, their relationship with severity and clinical evolution of AP, and their use as prognosis markers of AP. METHODS A case (25)-control (30) study was carried out. Patients with AP were classified according to severity (using Ranson and Glasgow scores) and according to their clinical evolution (taking into account the development of complications during hospital stay). Platelet-derived growth factor (PDGFBB), angiopoietin-1, angiopoietin-2 (Ang-2), angiopoietin tyrosine-kinase receptor, hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF), VEGF tyrosine-kinase receptor 1, and VEGF tyrosine-kinase receptor 2 were determined at 12 hours and then at 5 days after hospitalization. RESULTS PDGFBB, Ang-2, angiopoietin tyrosine-kinase receptor, and HGF were significantly higher in cases (P<0.001), and in patients with unfavorable clinical evolution (P<0.001). PDGFBB and HGF were significantly higher in patients with severe AP (P<0.05). To predict unfavorable clinical evolution, PDGFBB, Ang-2, and HGF showed an area under receiver operating characteristic curve of 0.97. CONCLUSIONS PDGFBB and HGF are related to severity of AP. These factors along with Ang-2 are related to clinical evolution and are useful in predicting the development of several complications during hospital stay. Therefore, these angiogenic factors could be useful as prognosis markers of AP.

Abstract
Studies on angiogenesis and lymphangiogenesis have gained special relevance in research into factors potentially influencing the pathogenesis and course of inflammatory bowel disease (IBD). The results of the few existing studies on the distribution and density of lymphatic vessels and blood vessels in the context of IBD are controversial. Studies using the specific lymphatic marker podoplanin have revealed a significantly large number of lymphatic vessels in the colonic mucosa of patients with ulcerative colitis and Crohn's disease (compared to patients with normal mucosa), whereas other authors have found no significant differences. However, the role of vascular endothelial growth factor (VEGF) tyrosine-kinase receptor 3 (VEGFR-3) in the onset of IBD has not been analyzed. In recent years new biochemical, molecular, and immunohistochemical studies indicate that several families of growth factors, such as the VEGF family and their receptors, fibroblast growth factor-2, platelet-derived growth factor-BB, hepatocyte growth factor, the angiopoietin system, and integrins may play an important role in the onset of IBD. To date, no comparative studies have analyzed these growth factors and specific lymphatic markers. We examine how growth factors are involved in the development of pathological lymphangiogenesis in patients with IBD and determine whether they play a crucial role in disease exacerbation.

Abstract
AIMS The aim of this study was to compare angiogenic factors in serum levels of active ulcerative colitis (UC) patients and in healthy controls, and to analyze these angiogenic levels depending on the achievement of remission after oral corticosteroid treatment throughout treatment, and according to the Truelove-Witts activity index. METHODS Blood samples were collected from 13 patients receiving oral corticosteroids for treatment of UC flares at three different intervals--baseline, during, and after treatment--and from 26 healthy controls. Vascular endothelial growth factor (VEGF), placental growth factor (PlGF), VEGF receptor 1 (VEGFR1), angiopoietins (Ang) 1 and 2, and its receptor Tie2 were assayed by ELISA. RESULTS While VEGF and Ang2 levels in UC patients were higher than in healthy controls (P < 0.05), UC patients showed lower levels of Ang1 than healthy individuals (P < 0.05). In UC patients who achieved clinical remission after corticosteroid treatment, a statistically significant higher baseline serum level of PlGF was observed (22 ± 5 vs. 18 ± 2; P < 0.05). Angiogenic factor levels varied during treatment; however, they did not show a statistically significant correlation to the activity of the disease. CONCLUSIONS VEGF, Ang1, and Ang2 levels showed statistically significant differences between UC patients and healthy controls. Although determination of PlGF serum levels before corticosteroid treatment might be helpful to anticipate the response by UC patients, no angiogenic pattern that could accurately predict "a priori" this response to corticosteroid treatment was observed. Corticosteroids altered temporarily circulating levels of VEGF, angiopoietins and Tie2. No correlation was found between systemic levels of angiogenic factors and the clinical activity of UC.

Abstract
AIMS Soluble angiogenic factors could be altered in patients with Crohns disease (CD), since inflammation and angiogenesis may play a critical pathogenic role. METHODS Serum samples were collected from 30 patients with CD (50% female; median age 44 +/- 14 yrs) grouped according to their phenotypic behavior into equal subgroups: inflammatory, fibrostenotic and fistulizing; and 30 healthy controls (50% female; median age 43 +/- 14 yrs). Vascular endothelial growth factor (VEGF), placental growth factor (PlGF), angiopoietins (Ang) and receptors (VEGFR1, VEGFR2 and Tie2) in sera were assayed by ELISA. RESULTS Serum levels of VEGF (494 +/- 247 pg/ml), PlGF (36 +/- 11 pg/ml), VEGFR1 (1.9 +/- 0.3 ng/ml), Ang2 (6.0 +/- 2.3 ng/ml) and Tie2 (36 +/- 5 ng/ml) in CD patients were significantly higher than those found in healthy controls (335 +/- 118 pg/ml; 23 +/- 9 pg/ml; 1.0 +/- 0.3 ng/ml; 3.9 +/- 2.0 ng/ml; 22 +/- 7 ng/ml, respectively). Conversely, CD patients showed significantly lower serum levels of Ang1 than healthy controls (46 +/- 11 versus 67 +/- 23 pg/ml). In the case of VEGFR2 serum levels, no differences between groups were found. Finally, patients with fibrostenotic CD were characterized by elevated VEGF and Ang2 levels, while patients with an inflammatory phenotype by elevated Tie2 and PlGF levels. CONCLUSIONS An activated "pro-angiogenic" profile of angiogenesis soluble markers was observed in CD patients, in comparison with healthy controls. According to the phenotypic behavior, these patients showed differences in serum levels of angiogenic factors.

Abstract
Both ulcerative colitis and Crohn's disease, the two major forms of inflammatory bowel diseases, are recognized, at the moment, as perplexing and challenging clinical entities, in which several molecules and cell types are implicated. Recent molecular evidence proposes the intestinal microvascular remodelling or angiogenesis, as a phenomenon implicated in the pathogenesis of these chronic inflammatory disorders, together with other proposed theories involved in the pathogenesis of inflammatory bowel diseases, such as genetic, microbacterial and immune factors. Intestinal damage is followed by a physiological angiogenesis, but the abnormal expression of pro- and anti-angiogenic molecules and the changes of vascular cell types could reflect a pathological vascular remodelling. Thus, the inflammation may be favoured and maintained by a pathological angiogenesis. A better understanding of the angiogenic process may facilitate the design of more effective therapies for chronic intestinal inflammation.

Abstract
Vascularization, under physiological or pathophysiological conditions, typically takes place by one or more of the following processes: angiogenesis, vasculogenesis, arteriogenesis, and lymphangiogenesis. Although all of these mechanisms of vascularization have sufficient contrasting features to warrant consideration under separate cover, one common feature shared by all is their sensitivity to the VEGF signaling pathway. Conditions such as wound healing and physical exercise result in increased production of reactive oxygen species such as H(2)O(2), and both are associated with increased tissue vascularization. Understanding these two scenarios of adult tissue vascularization in tandem offers the potential to unlock the significance of redox regulation of the VEGF signaling pathway. Does H(2)O(2) support tissue vascularization? H(2)O(2) induces the expression of the most angiogenic form of VEGF, VEGF-A, by a HIF-independent and Sp1-dependent mechanism. Ligation of VEGF-A to VEGFR2 results in signal transduction leading to tissue vascularization. Such ligation generates H(2)O(2) via an NADPH oxidase-dependent mechanism. Disruption of VEGF-VEGFR2 ligation-dependent H(2)O(2) production or decomposition of such H(2)O(2) stalls VEGFR2 signaling. Numerous antioxidants exhibit antiangiogenic properties. Current evidence lends firm credence to the hypothesis that low-level endogenous H(2)O(2) supports vascular growth.

Abstract
BACKGROUND The purposes of this study were to determine soluble angiogenic factors in Crohn's disease (CD) patients and to compare these factors according to the pathological behavior of the disease in order to establish a possible relationship with its evolution in patients with CD. METHODS Blood samples were collected from 70 patients with CD, grouped according to their phenotypic behavior, and from 30 healthy controls. Vascular endothelial growth factor (VEGF), placental growth factor (PlGF), angiopoietin 1 (Ang1), angiopoietin 2 (Ang2), and their cognate receptors [VEGFR1, VEGFR2, and angiopoietin receptor tyrosine kinase (Tie2)] were assayed by ELISA. RESULTS Circulating levels of VEGF, PlGF, VEGFR1, Ang2, and Tie2 were significantly higher in CD patients than in healthy controls (489 +/- 271 versus 335 +/- 118 pg/mL, P < 0.001; 31 +/- 9 versus 23 +/- 9 pg/mL, P < 0.001; 1.7 +/- 0.4 versus 1.0 +/- 0.3 ng/mL, P < 0.001; 4.8 +/- 2.0 versus 3.9 +/- 2.0 ng/mL, P < 0.05; and 36 +/- 5 versus 22 +/- 7 ng/mL, P < 0.001, respectively). Conversely, CD patients showed significantly lower serum levels of Ang1 than healthy controls (40 +/- 12 versus 67 +/- 22 ng/mL; P < 0.001). No differences between the groups were found in VEGFR2 serum level. The circulating levels of the angiogenic factors did not differ significantly when the CD patients were classified according to pathological phenotype. CONCLUSIONS In comparison with healthy controls, CD patients were found to have an active angiogenic profile, as detected by significant alterations in levels of angiogenesis soluble markers. These patients did not differ in serum levels of angiogenic factors according to phenotypic disease behavior.
