Oxidative and nitrosative stress in acute pancreatitis. Modulation by pentoxifylline and oxypurinol
2011
Item does not contain fulltext Reactive oxygen species are considered mediators of the inflammatory response and tissue damage in acute pancreatitis. We previously found that the combined treatment with oxypurinol - as inhibitor of xanthine oxidase- and pentoxifylline - as inhibitor of TNF-alpha production-restrained local and systemic inflammatory response and decreased mortality in experimental acute pancreatitis. Our aims were (1) to determine the time-course of glutathione depletion and oxidation in necrotizing pancreatitis in rats and its modulation by oxypurinol and pentoxifylline; (2) to determine whether TNF-alpha is responsible for glutathione depletion in acute pancreatitis; and (…
Necrotizing enterocolitis in the preterm: newborns medical and nutritional Management in a Single-Center Study
2021
AbstractNecrotizing enterocolitis (NEC) is a typical disorder of preterm newborns, with a high mortality and morbidity rate. The therapeutic and nutritional management of disease depends on several factors. Its prognosis is linked, in addition to the severity of the disease and the need for surgery, to a correct enteral feeding in these patients. This study aims to identify the clinical characteristics of 18 patients with NEC, evaluating the different therapeutic paths undertaken, the type of formula used and the survival rate of this population. Average time of enteral nutrition before the NEC onset was 11,3 ± 11,6 days, with an average fasting period since the onset of 24 ± 18.9 days. 77.…
Association of maternal hypertension and chorioamnionitis with preterm outcomes
2014
OBJECTIVES: We compared the relative effect of hypertensive disorders of pregnancy and chorioamnionitis on adverse neonatal outcomes in very preterm neonates, and studied whether gestational age (GA) modulates these effects. METHODS: A cohort of neonates 23 to 30 weeks' GA, born in 2008 to 2011 in 82 hospitals adhering to the Italian Neonatal Network, was analyzed. Infants born from mothers who had hypertensive disorders (N = 2096) were compared with those born after chorioamnionitis (N = 1510). Statistical analysis employed logistic models, adjusting for GA, hospital, and potential confounders. RESULTS: Overall mortality was higher after hypertension than after chorioamnionitis (odds rati…
Routine Probiotic Use in Very Preterm Infants: Retrospective Comparison of Two Cohorts
2013
International audience; OBJECTIVE: Evidence supports the efficacy of probiotics in reducing necrotizing enterocolitis (NEC) in very low-birth-weight infants, although concerns remain with regard to their routine use. Since 2008 in our neonatal intensive care unit, a low dose of probiotics (unique strain) is administered as standard of care in all preterm babies born at 24 to 31 weeks' gestation. This study reports outcomes in infants receiving probiotic cohort (PC) compared with the historical cohort. DESIGN: Treatment with Lactobacillus rhamnosus Lcr35 (Lcr Restituo) (2 × 108 colony-forming units/12 h) was started early after birth and intention to treat was up to 36 weeks' gestation. The …
Influence of nutritional variables on the onset of necrotizing enterocolitis in preterm infants: A case-control study.
2016
• Minimal enteral feeding should be early initiated and prolonged for at least 5–7 days in the most immature newborn.
Glutamate cysteine ligase up-regulation fails in necrotizing pancreatitis
2007
Glutathione depletion is a key factor in the development of acute pancreatitis. Our aim was to study the regulation of glutamate cysteine ligase, the rate-limiting enzyme in glutathione synthesis, in edematous or necrotizing pancreatitis in rats. Glutathione levels were kept low in necrotizing pancreatitis for several hours, with no increase in protein or mRNA levels of glutamate cysteine ligase subunits, despite binding of RNA polymerase II to their promoters and coding regions. The survival signal pathway mediated by ERK and c-MYC was activated, and c-MYC was recruited to the promoters. The failure in gene up-regulation seems to be due to a marked increase in cytosolic ribonuclease activi…
Pancreatic ascites hemoglobin contributes to the systemic response in acute pancreatitis.
2015
Upon hemolysis extracellular hemoglobin causes oxidative stress and cytotoxicity due to its peroxidase activity. Extracellular hemoglobin may release free hemin, which increases vascular permeability, leukocyte recruitment, and adhesion molecule expression. Pancreatitis-associated ascitic fluid is reddish and may contain extracellular hemoglobin. Our aim has been to determine the role of extracellular hemoglobin in the local and systemic inflammatory response during severe acute pancreatitis in rats. To this end we studied taurocholate-induced necrotizing pancreatitis in rats. First, extracellular hemoglobin in ascites and plasma was quantified and the hemolytic action of ascitic fluid was …
Cervical necrotizing fasciitis and descending necrotizing mediastinitis in a patient affected by neglected peritonsillar abscess: a case of medical n…
2007
Abstract We report a case of fatal cervical necrotizing fasciitis (CNF) and descending necrotizing mediastinitis (DNM) due to primary peritonsillar abscess in 60-year-old male patient with no history or evidence of immunocompromising disorders. The patient was treated with antibiotic and corticosteroid drugs but he developed mediastinitis and septic shock and died of multiple organ failure six days later from recovery in hospital. After a clinical, diagnostic and therapeutical consideration of the cervical necrotizing fasciitis and some related risks of a delayed diagnosis and treatment, the authors analysed the clinical history of the patient and of the medical conduct pointing out profess…
Pancreatic T cell protein-tyrosine phosphatase deficiency ameliorates cerulein-induced acute pancreatitis.
2014
Background Acute pancreatitis (AP) is a common clinical problem whose incidence has been progressively increasing in recent years. Onset of the disease is trigged by intra-acinar cell activation of digestive enzyme zymogens that induce autodigestion, release of pro-inflammatory cytokines and acinar cell injury. T-cell protein tyrosine phosphatase (TCPTP) is implicated in inflammatory signaling but its significance in AP remains unclear. Results In this study we assessed the role of pancreatic TCPTP in cerulein-induced AP. TCPTP expression was increased at the protein and messenger RNA levels in the early phase of AP in mice and rats. To directly determine whether TCPTP may have a causal rol…
Fatal necrotising fasciitis associated with intramuscular injection of nonsteroidal anti-inflammatory drugs after uncomplicated endoscopic polypectom…
2007
Summary Necrotising fasciitis is a life-threatening infection of the superficial muscle fascia and the adjacent deep layer of subcutaneous tissue that is often fatal. A 46-year-old woman was admitted to the intensive care unit (ICU) three days after an uncomplicated endoscopic polypectomy because of necrotising fasciitis of left tight, buttock and retroperitoneal space and septic shock. Six hours after the polypectomy she was given an intramuscular injection of ketorolac in the left tight because of moderate low abdominal pain. Twelve and 24h later she was treated with another two intramuscular injection of diclofenac in the left tight for severe pains in the left hip joint region. The shoc…
