Influence of HMG-CoA reductase inhibitors on markers of coagulation, systemic inflammation and soluble cell adhesion.
2002
Abstract Background: Beneath its lipid-lowering properties additional non-lipid effects of statin therapy are discussed. We therefore examined the impact of statins on laboratory markers of coagulation, inflammation and soluble cell adhesion to further explore these effects in 950 hospitalised patients with angiographically proven CAD. Methods and results: Although no significant differences were found in total cholesterol, LDL and HDL and triglyceride levels a statistically lower value in 277 statin-treated patients was found for von Willebrand factor [162(130/224) vs. 208(154/283)%, P =0.0001], leukocyte count [6.9(5.8/8.4) vs. 7.3(6.1/9.4)/nl, P =0.0005], high sensitive CRP [4.3(1.8/10.8…
Insulin resistance as common molecular denominator linking obesity to Alzheimer’s disease
2015
Alzheimer’s disease (AD) is an aging-related multi-factorial disorder to which metabolic factors contribute at what has canonically been considered a centrally mediated process. Although the exact underlying mechanisms are still unknown, obesity is recognized as a risk factor for AD and the condition of insulin resistance seems to be the link between the two pathologies. Using mice with high fat diet (HFD) obesity we dissected the molecular mechanisms shared by the two disorders. Brains of HFD fed mice showed elevated levels of APP and Aβ 40 /Aβ 42 together with BACE, GSK3β and Tau proteins involved in APP processing and Aβ accumulation. Immunofluorescence, Thioflavin T staining experiments…
Prognostic Value of White Blood Cell Count in Acute Myocardial Infarction: Long-Term Mortality
2005
Although traditionally an elevated white blood cell count (WBC), an indicator of systemic inflammation, has been accepted as part of the healing response following acute myocardial infarction (AMI), it has frequently been shown to be a predictor of adverse cardiovascular events. The present study was designed to assess the association between WBC and long-term mortality in AMI patients either with ST-segment elevation (STEMI) or without ST-segment elevation (non-STEMI). Patients and method. The study included 1118 consecutive patients who were admitted with the diagnosis of AMI: 569 non-STEMI and 549 STEMI. The WBC was measured in the 24 hours following admission. Patients were divided into…
Ocular ductions after rectus muscle recession and resection in thyroid eye disease.
2019
Background: Recession and resection of rectus muscles for correction of strabismus in Thyroid Eye Disease (TED) is relatively unpopular as it is assumed to enhance the restriction of ocular ductions. Therefore, the purpose of this study was to compare ductions of recession only and recess/resect procedures. Methods: We retrospectively reviewed the charts of 119 patients who underwent strabismus surgery for TED from 1991 to 2015, of which 102 were included in the present study. Forty-six interventions were performed on horizontal, 56 on vertical rectus muscles; comprising 41 recess/resect surgeries for horizontal deviations, and 7 in patients with vertical strabismus. Ocular ductions and ali…
A Multiplex Panel of Plasma Markers of Immunity and Inflammation in Classical Kaposi Sarcoma
2014
Kaposi sarcoma (KS) risk is affected by perturbed immunity. Herein, we compared plasma from 15 human immunodeficiency virus (HIV)–negative classic KS cases to plasma from 29 matched controls, using a multiplex panel of immunity markers. Of 70 markers, CXCL10 (IP-10), sIL-1RII, sIL-2RA, and CCL3 (MIP-1A) were strongly and significantly associated with KS, after adjustment for age and smoking status. These and previous observations are consistent with a tumor-promoting role for these cytokines, particularly CXCL10, but the small sample size and case-control design preclude firm conclusions on KS risk or pathogenesis. Larger, well-designed prospective studies are needed to better assess the as…
Targeting transcription factor Stat4 uncovers a role for interleukin-18 in the pathogenesis of severe lupus nephritis in mice
2011
Polymorphisms in the transcription factor Stat4 gene have been implicated as risk factors for systemic lupus erythematosus. Although some polymorphisms have a strong association with autoantibodies and nephritis, their impact on pathophysiology is still unknown. To explore this further we used signal transducers and activators of transcription 4 (Stat4) knockout MRL/MpJ-Fas(lpr)/Fas(lpr) (MRL-Fas(lpr)) mice and found that they did not differ in survival or renal function from Stat4-intact MRL-Fas(lpr) mice. Circulating interleukin (IL)-18 levels, however, were elevated in Stat4-deficient compared to Stat4-intact mice, suggesting that this interleukin might contribute to the progression of l…
Cardiac Injury in COVID-19–Echoing Prognostication∗
2020
Background Myocardial injury is frequent among patients hospitalized with coronavirus disease-2019 (COVID-19) and is associated with a poor prognosis. However, the mechanisms of myocardial injury remain unclear and prior studies have not reported cardiovascular imaging data. Objectives This study sought to characterize the echocardiographic abnormalities associated with myocardial injury and their prognostic impact in patients with COVID-19. Methods We conducted an international, multicenter cohort study including 7 hospitals in New York City and Milan of hospitalized patients with laboratory-confirmed COVID-19 who had undergone transthoracic echocardiographic (TTE) and electrocardiographic…
Monocytes from patients with rheumatoid arthritis and type 2 diabetes mellitus display an increased production of interleukin (IL)-1β via the nucleot…
2015
Summary A better understanding about the mechanisms involved in the pathogenesis of type 2 diabetes mellitus (T2D) showed that inflammatory cytokines such as tumour necrosis factor (TNF) and interleukin (IL)-1β play a pivotal role, mirroring data largely reported in rheumatoid arthritis (RA). IL-1β is produced mainly by monocytes (MO), and hyperglycaemia may be able to modulate, in the cytoplasm of these cells, the assembly of a nucleotide-binding domain and leucine-rich repeat containing family pyrin (NLRP3)-inflammosome, a cytosolic multi-protein platform where the inactive pro-IL-1β is cleaved into active form, via caspase-1 activity. In this paper, we evaluated the production of IL-1 β …
Functional response of novel bioprotective poloxamer-structured vesicles on inflamed skin
2017
[EN] Resveratrol and gallic acid, a lipophilic and a hydrophilic phenol, were co-loaded in innovative, biocompatible nanovesicles conceived for ensuring the protection of the skin from oxidative-and inflammatory-related affections. The basic vesicles, liposomes and glycerosomes, were produced by a simple, one-step method involving the dispersion of phospholipid and phenols in water or water/glycerol blend, respectively. Liposomes and glycerosomes were modified by the addition of poloxamer, a stabilizer and viscosity enhancer, thus obtaining viscous or semisolid dispersions of structured vesicles. The vesicles were spherical, unilamellar and small in size (similar to 70 nm in diameter). The …
Influence of heme oxygenase 1 modulation on the progression of murine collagen-induced arthritis.
2005
Contains fulltext : 48023.pdf (Publisher’s version ) (Closed access) OBJECTIVE: Heme oxygenase 1 (HO-1) can be induced by inflammatory mediators as an adaptive response. The objective of the present study was to determine the consequences of HO-1 modulation in the murine collagen-induced arthritis (CIA) model. METHODS: DBA/1J mice were treated with an inhibitor of HO-1, tin protoporphyrin IX (SnPP), or with an inducer of HO-1, cobalt protoporphyrin IX (CoPP), from day 22 to day 29 after CIA induction. The clinical evolution of disease was monitored visually. At the end of the experiment, joints were examined for histopathologic changes. Cytokine levels in paws were measured by enzyme-linked…
