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…

Toll-like receptor 5 in obesity: The role of gut microbiota and adipose tissue inflammation

2015

Objective This study aimed at establishing bacterial flagellin-recognizing toll-like receptor 5 (TLR5) as a novel link between gut microbiota composition, adipose tissue inflammation, and obesity. Methods An adipose tissue microarray database was used to compare women having the highest (n = 4, H-TLR) and lowest (n = 4, L-TLR) expression levels of TLR5-signaling pathway genes. Gut microbiota composition was profiled using flow cytometry and FISH. Standard laboratory techniques were used to determine anthropometric and clinical variables. In vivo results were verified using cultured human adipocytes. Results The H-TLR group had higher flagellated Clostridium cluster XIV abundance and Firmicu…

n-3 Fatty Acids Modulate T-Cell Calcium Signaling in Obese Macrosomic Rats

2004

Objective: We investigated the effects of a diet containing EPAX-7010, rich in PUFAs such as eicosapentaenoic acid [20:5(n-3)] and docosahexaenoic acid [22:6(n-3)], i.e., a PUFA/EPAX regimen, on T-cell activation in diabetic pregnant rats and their obese pups. Research Methods and Procedures: Mild hyperglycemia in pregnant rats was induced by intraperitoneal injection of streptozotocin on Day 5 of gestation. T-cell blastogenesis was assayed by using 3H-thymidine, whereas intracellular free calcium concentrations ([Ca2+]i) were measured by using Fura-2 in diabetic pregnant rats and their obese offspring. Results: Concavalin-A-stimulated T-cell proliferation was decreased in both pregnant dia…

Age-related changes in cholesterol metabolism in macrosomic offspring of rats with streptozotocin-induced diabetes.

2001

The aim of this study was to determine the impact of diabetic macrosomia on cholesterol and lipoprotein metabolism. Age-related changes in the activities of serum LCAT, hepatic HMG-CoA reductase, cholesterol 7α-hydroxylase, and ACAT, the major enzymes involved in cholesterol metabolism, were determined in macrosomic offspring of streptozotocin-induced diabetic rats. Hepatic, serum, and lipoprotein cholesterol contents were also examined. Mild hyperglycemia in pregnant rats was induced by intraperitoneal injection of streptozotocin (40 mg/kg body weight) on day 5 of gestation. Control pregnant rats were injected with citrate buffer. At birth, macrosomic pups had higher serum, LDL-HDL1, and H…

Bisphosphonates and atherosclerosis: why?

2005

The increasing knowledge on bone calcification processes has revealed some similarities with vascular tissue, where calcifications of arteries and cardiac valves contribute to several cardiovascular problems, such as heart failure, systolic hypertension, and myocardial and peripheral ischemic disease. Bisphosphonates have been used extensively for over two decades for the treatment of diseases associated with excessive bone resorption, i.e., osteoporosis, osteolytic bone metastasis, hypercalcemia and Paget’s disease, by blocking osteoclastic function. Etidronate, pamidronate and clodronate has been shown to inhibit the development of experimental atherosclerosis, and proposed mechanisms fo…

Interrelation of peptidergic innervation with mast cells and ED1-positive cells in rat thymus

1991

The peptidergic innervation of rat thymus has been investigated by immunohistochemical methods, focusing on the spatial interrelationship of peptidergic nerve fibers with mast cells and macrophages in the rat. An antiserum directed against the protein gene product 9.5 (PGP 9.5) regarded as a pan-neuronal marker revealed a rich innervation, especially in the subcapsular cortex, in interlobular septa, and of the vasculature in the cortex and the corticomedullary boundary. A minor proportion of PGP 9.5-immunoreactive (ir) fibers supplied the thymic parenchyma. The main component of peptidergic innervation consisted of fibers costaining for tachykinins (TKs) and calcitonin gene-related peptide …

PReS-FINAL-2088: Risk of severe adverse events in juvenile idiopathic arthritis and pediatric-onset inflammatory bowel disease, treated with anti-tnf…

2013

Introduction: Severe adverse events have been described in children affected by Juvenile Idiopathic Arthritis (JIA) and Inflammatory Bowel Disease (IBD) treated with anti-tnf drugs. Objectives: To define the risk of severe adverse events in patients with JIA and IBD treated with anti-tnf drugs. Methods: This is a retrospective cohort study. All patients with JIA and IBD attending the "IRCCS Burlo Garofolo" of Trieste from 2000 to 2012 were enrolled. They were divided into 2 groups on the basis of the presence or absence of anti-tnf exposure. Severe adverse events were considered the followings: a) infections needing anti-tnf permanent suspension and/or hospitalization; b) autoimmune disease…

Oral capecitabine and Vinorelbine in Metastatic Breast Cancer. A Retrospective Analysis of Tolerability and Activity

2012

ABSTRACT Background The purpose of this study was to retrospectively analyze toxicity profile and activity of an all-oral combination schedule of Capecitabine (Cape) and Vinorelbine (VNR) in metastatic breast cancer (MBC) patients (pts). Methods All pts treated had a histological confirmed diagnosis of breast cancer (BC). Each 3-week cycle of treatment consisted of 500 mg/m2 cape twice daily (2 weeks on, 1 week off), and 60 mg/m2 VNR on days 1 and 8. Results From June'07 to December'11 we analyzed 77 MBC pts. Median age was 52 years (range 34-73). 58 pts (75,3%) had a performance status (PS) ECOG 0; 13 pts (16,8%) PS1, 6 pts (7,8%) PS2. 5 pts (6,5%) had metastatic disease at time of diagnos…

Macro and microrheological determinants in chronic renal failure

Hypertension and atrial fibrillation: diagnostic approach, prevention and treatment. Position paper of the Working Group 'Hypertension Arrhythmias an…

2012

Hypertension is the most common cardiovascular disorder and atrial fibrillation is the most common clinically significant arrhythmia. Both these conditions frequently coexist and their prevalence increases rapidly with aging. There are different risk factors and clinical conditions predisposing to the development of atrial fibrillation, but due its high prevalence, hypertension is still the main risk factor for the development of atrial fibrillation. Several pathophysiologic mechanisms (such as structural changes, neurohormonal activation, fibrosis, atherosclerosis, etc.) have been advocated to explain the onset of atrial fibrillation. The presence of atrial fibrillation per se increases th…
