Building a continuous multicenter infection surveillance system in the intensive care unit: findings from the initial data set of 9,493 patients from…

2008

OBJECTIVE: To describe the epidemiology of infections in intensive care units (ICUs), whether present at admission or acquired during the stay. METHODS: Prospective data collection lasting 6 months in 71 Italian adult ICUs. Patients were screened for infections and risk factors at ICU admission and daily during their stay. MAIN RESULTS: Out of 9,493 consecutive patients admitted to the 71 ICUs, 11.6% had a community-acquired infection, 7.4% a hospital-acquired infection, and 11.4% an ICU-acquired infection. The risk curve of acquiring infection in the ICU was higher in patients who entered without infection than in those already infected (log-rank test, p < .0001; at 15 days, 44.0% vs. 34.6…

The early immune response in the liver of BALB/c mice infected with S. typhimurium.

2000

Gram-negative bacteria acquired through gastrointestinal infection can be a serious cause for the development of septic shock especially in immunosuppressed patients. Thus, the aim of this study was to examine the early events of the immune reaction against S. typhimurium. Bacteria were injected into mice at different concentrations. Four animals from each group were killed at five different points of time. Liver cytokine mRNA expression was determined by semiquantitative rt-PCR and liver histology was examined. Serum cytokine levels of interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-4 and IL-10 were determined. intravenous (i.v.) infection with 109 bacteri…

Vasopressor-Sparing Strategies in Patients with Shock: A Scoping-Review and an Evidence-Based Strategy Proposition

2021

Despite the abundant literature on vasopressor therapy, few studies have focused on vasopressor-sparing strategies in patients with shock. We performed a scoping-review of the published studies evaluating vasopressor-sparing strategies by analyzing the results from randomized controlled trials conducted in patients with shock, with a focus on vasopressor doses and/or duration reduction. We analyzed 143 studies, mainly performed in septic shock. Our analysis demonstrated that several pharmacological and non-pharmacological strategies are associated with a decrease in the duration of vasopressor therapy. These strategies are as follows: implementing a weaning strategy, vasopressin use, system…

Circulating Histones and Nucleosomes as Biomarkers in Sepsis and Septic Shock

2016

Sepsis, severe sepsis, and septic shock are among the leading causes of death worldwide and their incidence is constantly increasing. Despite early intervention in intensive care units (ICUs) mortality remains high. There is great interest in understanding the genetics and epigenetics of the host in response to infection because of two reasons: the peculiarities of each patient, and the unclear associations identified between genetic polymorphisms and susceptibility to sepsis. In addition, chromatin remodeling and epigenetic changes occur in crucial genes involved in the inflammatory response and also in the immunosuppression found in sepsis. The early and accurate diagnosis of sepsis is a …

Circular RNAs in Sepsis: Biogenesis, Function, and Clinical Significance

2020

Sepsis is a life-threatening condition that occurs when the body responds to an infection that damages it is own tissues. The major problem in sepsis is rapid, vital status deterioration in patients, which can progress to septic shock with multiple organ failure if not properly treated. As there are no specific treatments, early diagnosis is mandatory to reduce high mortality. Despite more than 170 different biomarkers being postulated, early sepsis diagnosis and prognosis remain a challenge for clinicians. Recent findings propose that circular RNAs (circRNAs) may play a prominent role in regulating the patients’ immune system against different pathogens, including bacteria and viruses. Mou…

Association between increased arterial stiffness and clinical outcomes in patients with early sepsis: a prospective observational cohort study.

2019

Background Conduit arteries, especially the aorta, play a major role in ensuring efficient cardiac function and optimal microvascular flow due to their viscoelastic properties. Studies in animals and on isolated arteries show that acute systemic inflammation can cause aortic stiffening which affects hemodynamic efficiency. Carotid-femoral pulse wave velocity, a measure of aortic stiffness, may be useful as a bedside investigational method in patients with early sepsis admitted to intensive care, as circulatory changes can lead to multiple organ failure and increased mortality. This study aims to investigate arterial stiffness in early sepsis and its association with clinical outcomes. Metho…

Severe Clostridium difficile infection with extremely high leucocytosis complicated by a concomitant bloodstream infection caused by Klebsiella pneum…

2020

Highlights • Exposure to antibiotics after surgery increase risk of Cl. difficile infection. • Sudden high leucocytosis may be sign of poor outcome in Cl. difficile case. • Oral Vancomycin could be responsible for the growth of bloodstream Kl. pneumonia.

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…
