Complement C6 deficiency protects against diet-induced atherosclerosis in rabbits.
1998
Abstract —Low-density lipoprotein (LDL) can be transformed to an atherogenic moiety by nonoxidative, enzymatic degradation. Enzymatically degraded LDL induces macrophage foam cell formation, provokes release of cytokines, and also activates complement. To determine whether complement activation may contribute to atherogenesis, 6 pairs of homozygous C6-deficient rabbits and their non–C6-deficient heterozygous siblings were fed a cholesterol-rich diet for 14 weeks. Cholesterol levels and plasma lipoprotein profiles of the animals in the C6-competent and C6-deficient groups did not significantly differ, and the high density lipoprotein and LDL cholesterol ratios at the end of the experiment w…
Biochemical and histological alterations of cellular metabolism from jerboa (Jaculus orientalis) by 2,4-dichlorophenoxyacetic acid: Effects on d-3-hy…
2007
?; International audience; 2,4-Dichlorophenoxyacetic acid (2,4D) is one of the widely used herbicide of the phenoxy family with possible startling number of adverse effects on species other than the weeds which is designed to kill. The effects of 2,4D were investigated in jerboa (Jaculus orientalis), a wild animal of subdesert highlands. The jerboas have been daily treated intraperitonally with 2,4D 3 mg/kg body weight for 4 weeks. Plasmatic markers, and antioxidants defences systems were assessed and histological alterations were evaluated. The in vivo and in vitro effects of 2,4D on the mitochondrial D-3-hydroxybutyrate dehydrogenase (BDH) were also determined. Our results showed a strong…
FRI0504 Prognostic Factors of Adult Onset Still's Disease: Analysis of 100 Cases in 3 Tertiary Referral Centers
2016
Background Adult onset Still9s disease (AOSD) is rare inflammatory disease [1]. Three different patterns of AOSD have been identified: i. monocyclic pattern, characterized by a systemic single episode; ii. polycyclic pattern, associated with multiple flares, separated by remissions; iii. chronic pattern, related to a persistently active disease with associated polyarthritis [2]. Until now, the treatment of AOSD remains largely empirical, lacking controlled clinical trials [1]. Objectives We aimed to investigate clinical data of AOSD patients and any possible correlation among these features and the outcome of patients. Methods Clinical data of 100 AOSD patients were recorded. All patients f…
THU0582 Prognostic Factors of Macrophage Activation Syndrome in Adults: Analysis of 40 Cases in 2 Tertiary Referral Centers
2016
Background Macrophage activation syndrome (MAS) is a rare, life-threatening disease in which early diagnosis and aggressive therapeutic strategy may improve the outcome [1]. Due to its rarity, epidemiologic data are still lacking. Hyperferritinemia is frequently associated with MAS and might modulate the cytokines storm the latter contributing to the development of multi-organ failure [2]. Objectives In the current study, we aimed to investigate clinical data, treatments, and outcome of adult MAS patients secondary to autoimmune rheumatic disease. Methods We retrospectively investigated clinical data, treatments, and outcome of 40 adult MAS patients secondary to autoimmune rheumatic disease…
Neurological impairment in experimental antiphospholipid syndrome is associated with increased ligand binding to hippocampal and cortical serotonergi…
2013
The antiphospholipid syndrome (APS) is an autoimmune disease where the presence of high titers of circulating autoantibodies causes thrombosis with consecutive infarcts. In experimental APS (eAPS), a mouse model of APS, behavioral abnormalities develop in the absence of vessel occlusion or infarcts. Using brain hemispheres of control and eAPS mice with documented neurological and cognitive deficits, we checked for lymphocytic infiltration, activation of glia and macrophages, as well as alterations of ligand binding densities of various neurotransmitter receptors to unravel the molecular basis of this abnormal behavior. Lymphocytic infiltrates were immunohistochemically characterized using a…
Intraperitoneal injection of tetracyclines protects mice from lethal endotoxemia downregulating inducible nitric oxide synthase in various organs and…
1997
We have tested whether tetracyclines (TETs) are able to protect mice from lipopolysaccharide (LPS)-induced shock, a cytokine-mediated inflammatory reaction. Mice, injected with a single dose of tetracycline base (TETb; 1.5, 10 and 20 mg/kg of body weight) or doxycycline (DOXY; 1.5 mg/kg), were significantly protected from a lethal intraperitoneal injection of LPS (500 micrograms per mouse). TETs acted in early events triggered in response to LSP; in fact, they were no longer significantly protective if injected more than 1 h after the injection of endotoxin. LPS-treated mice protected by TETs showed a significant inhibition of tumor necrosis factor alpha (TNF-alpha), interleukin-1 alpha (IL…
Initiation and progression of atherosclerosis – enzymatic or oxidative modification of low-density lipoprotein?
2006
AbstractAtherosclerosis is widely regarded as a chronic inflammatory disease that develops as a consequence of entrapment of low-density lipoprotein (LDL) in the arterial intima. Native LDL lacks inflammatory properties, so the lipoprotein must undergo biochemical alterations to become atherogenic. Among several other candidates, two different concepts of lipoprotein modification are propagated, the widespread oxidation hypothesis and the less common E-LDL hypothesis, which proposes that modification of LDL occurs through the action of ubiquitous hydrolytic enzymes (enzymatically modified LDL or E-LDL) rather than oxidation. By clearly distinguishing between the initiation and progression o…
Canakinumab in systemic juvenile idiopathic arthritis: real-world data from a retrospective Italian cohort
2021
Abstract Objective The objective of this study was to use real-world data to evaluate the effectiveness and safety of canakinumab in Italian patients with systemic JIA (sJIA). Methods A retrospective multicentre study of children with sJIA was performed. Clinical features, laboratory parameters and adverse events were collected at baseline, and 6 and 12 months after starting canakinumab. The primary outcome measure of effectiveness was clinically inactive disease (CID) off glucocorticoids (GCs) treatment at 6 months. Results A total of 80 children from 15 Italian centres were analysed. Of the 12 patients who started canakinumab in CID while receiving anakinra, all maintained CID. Of the 68 …
The neuro-B cell link of peptidergic innervation in the Bursa Fabricii
1991
The Bursa Fabricii, restricted to birds, specifically provides the microenvironment for B-cell maturation. The presence of nerve fibers containing immunopotent neuropeptides in immune organs opens interesting perspectives on the understanding of neuroimmune communication. As an organ for the development of only B-lymphocytes is not known in mammals, the contribution of a peptidergic innervation to the microenvironment of B-cells is not known. Therefore, we studied the peptidergic innervation of the Bursa Fabricii as an organ of B-cell maturation. Four different neuropeptides were found in nerve fibers of the Bursa Fabricii: tachykinins (TK), vasoactive intestinal peptide (VIP), galanin (GAL…
Fresh cell therapy followed by fatal coma
1986
A 60-year-old woman received a 3-day course of nine injections of “fresh” cells from fetal lamb ovary, placenta, brain (hypothalamus) and liver. There were no immediate complications, but a few days later she developed headache, fever and hemiparesis. She subsequently fell into a coma and died 3 weeks after her fresh cell therapy and 2 weeks after the onset of her clinical symptoms. Autopsy revealed perivenous leucoencephalopathy with a probably steroid-treatment-induced paucity of perivascular inflammation. Fresh cell therapy, clinical symptomatology and morphological findings suggest, though do not prove, that this patient's monophasic and probably immune-mediated disease is a rare and fa…
