The Dual Role of the GABAA Receptor in Peripheral Inflammation and Neuroinflammation: A Study in Hyperammonemic Rats
2021
Cognitive and motor impairment in minimal hepatic encephalopathy (MHE) are mediated by neuroinflammation, which is induced by hyperammonemia and peripheral inflammation. GABAergic neurotransmission in the cerebellum is altered in rats with chronic hyperammonemia. The mechanisms by which hyperammonemia induces neuroinflammation remain unknown. We hypothesized that GABAA receptors can modulate cerebellar neuroinflammation. The GABAA antagonist bicuculline was administrated daily (i.p.) for four weeks in control and hyperammonemic rats. Its effects on peripheral inflammation and on neuroinflammation as well as glutamate and GABA neurotransmission in the cerebellum were assessed. In hyperammone…
Complement activation by oxidatively modified low-density lipoproteins
1999
Background Oxidatively modified low-density lipoproteins (LDLs) have been implicated in the pathogenesis of atherosclerosis and are found in human vascular lesions. There is increasing evidence that complement activation may also play a role in atherogenesis. Activated complement proteins have been demonstrated to be present in early atherosclerotic lesions, and lipids isolated from lesions have been shown to activate complement, hence their designation as lesion complement activator (LCA). The question now arose whether oxidized LDLs would also activate complement. Material and methods The complement-activating capacity of a lesion complement activator preparation and of minimally as well …
Atherosclerosis, degenerative aortic stenosis and statins
2009
Aortic stenosis is the most common valvular heart disease among adult subjects in western countries The current treatment for aortic stenosis is aortic valve replacement. The possibility of a medical treatment that can slow the progression of aortic stenosis is very fascinating and statins have been tested to reduce the progression of degenerative aortic stenosis (DAS). The rationale for statin treatment in DAS has a deep pathophysiological substrate, in fact inflammation and lipid infiltration constitute the same histopathological pattern of both aortic stenosis and atherosclerosis and these two conditions have the same risk factors. Whether retrospective studies have shown some efficacy o…
The Role of Endothelium in COVID-19
2021
The 2019 novel coronavirus, known as severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) or coronavirus disease 2019 (COVID-19), is causing a global pandemic. The virus primarily affects the upper and lower respiratory tracts and raises the risk of a variety of non-pulmonary consequences, the most severe and possibly fatal of which are cardiovascular problems. Data show that almost one-third of the patients with a moderate or severe form of COVID-19 had preexisting cardiovascular comorbidities such as diabetes mellitus, obesity, hypertension, heart failure, or coronary artery disease. SARS-CoV2 causes hyper inflammation, hypoxia, apoptosis, and a renin–angiotensin system imbalance …
Randomised trial of mycophenolate mofetil versus azathioprine for treatment of chronic active Crohn’s disease
1999
BACKGROUNDCrohn’s disease is a chronic inflammatory disease of the alimentary tract. Azathioprine is an effective agent in the management of chronic active Crohn’s disease leading to long term remission of disease activity. Such treatment leads to limited efficacy or side effects in a small subset of patients.AIMSTo compare efficacy and side effects of treatment with azathioprine plus corticosteroids versus mycophenolate mofetil (MMF) plus corticosteroids in patients with chronic active Crohn’s disease.METHODSSeventy patients with chronic active Crohn’s disease (Crohn’s disease activity index (CDAI) greater than 150) were randomised for treatment with azathioprine/cortisone or MMF/cortisone…
P215 Blood-based prognostic biomarkers in Crohn’s patients treated with biologics: a new promising tool to predict endoscopic outcomes
2021
Abstract Background There is a growing need for biomarkers of inflammation to monitor and predict therapeutic outcome in Crohn’s disease (CD) patients. We aimed to evaluate whether the level of circulating blood cells, expressed as ratios (NLR, neutrophil-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; ELR, eosinophil-to-lymphocyte ratio and ENLR, eosinophil*neutrophil-to-lymphocyte ratio), could be used as early prognostic biomarker of endoscopic response (ER) in patients starting biological therapy with infliximab, adalimumab, vedolizumab and ustekinumab. Association with steroid-free clinical remission at week 54 and endoscopic disease activity at baseline, as well as other varia…
P162 Prevalence of nafld (non alcoholic fatty liver disease) and fibrosis in inflammatory bowel disease: the impact of traditional risk factors, inte…
2020
Abstract Background Prevalence of NAFLD has recently been reported increased in inflammatory bowel disease (IBD) with conflicting results due to heterogeneity of published studies, especially in the diagnostic definition of NAFLD. The increased risk of NAFLD might be related to traditional risk factors but also to IBD-related factors. The role of genetic markers has been addressed only in one study. The aim of our study has been to assess the prevalence of NAFLD and fibrosis in a homogeneous cohort of patients with IBD, assessing the role of metabolic, disease-related and genetic factors. Methods the diagnosis of NAFLD was based on transient fibroelastometry findings (CAP ≥288 dB/m) and HSI…
Renal Lipotoxicity-Associated Inflammation and Insulin Resistance Affects Actin Cytoskeleton Organization in Podocytes
2015
In the last few decades a change in lifestyle has led to an alarming increase in the prevalence of obesity and obesity-associated complications. Obese patients are at increased risk of developing hypertension, heart disease, insulin resistance (IR), dyslipidemia, type 2 diabetes and renal disease. The excess calories are stored as triglycerides in adipose tissue, but also may accumulate ectopically in other organs, including the kidney, which contributes to the damage through a toxic process named lipotoxicity. Recently, the evidence suggests that renal lipid accumulation leads to glomerular damage and, more specifically, produces dysfunction in podocytes, key cells that compose and maintai…
Use of leukocyte and platelet-rich fibrin (L-PRF) in periodontally accelerated osteogenic orthodontics (PAOO): clinical effects on edema and pain
2015
Background Demand for shorter treatment time is common in orthodontic patients. Periodontally Accelerated Osteogenic Orthodontics (PAOO) is a somewhat new surgical procedure which allows faster tooth movement via combining orthodontic forces with corticotomy and grafting of alveolar bone plates. Leukocyte and Platelet-Rich Fibrin (L-PRF) possess hard- and soft-tissue healing properties. Further, evidence of pain-inhibitory and anti-inflammatory potential is growing. Therefore, this study explores the feasibility, intra- and post-operative effects of using L-PRF in PAOO in terms of post-operative pain, inflammation, infection and post-orthodontic stability. Material and methods A pilot prosp…
Oral Health Scales: Design of an Oral Health Scale of Infectious Potential
2013
Objectives: In this paper we propose a new Global Oral Health Scale that will allow the infectious potential of the oral cavity, clinically manifest as local and focal infections, to be condensed into a single parameter. Study Design: Based on a number of oral health scales previously designed by our group, we designed a final version that incorporates dental and periodontal variables (some of them evaluated using corroborated objective indices) that reflect the presence of caries and periodontal disease. Results: The application of the proposed oral health scale requires the examination of 6 sites per tooth (mesio- buccal, medio-buccal, disto-buccal, disto-lingual, medio-lingual and mesio-…
