Colistin pharmacokinetics were prospectively studied after intravenous administration of colistin methanesulphonate in critically ill patients without central nervous system infection (controls, n = 5) and in patients with external ventricular drain-associated ventriculitis after intravenous administration (EVDViv, n = 3) or combined(More)
INTRODUCTION Two small randomized controlled trials have suggested beneficial effects of antibiotic treatment in patients with ventilator-associated tracheobronchitis (VAT). The primary aim of this study is to determine the impact of appropriate antibiotic treatment on transition from VAT to ventilator-associated pneumonia (VAP) in critically ill patients.(More)
OBJECTIVE To assess the prevalence and outcome of external cerebral ventricular drainage-associated ventriculitis in neurocritical patients before and after the implementation of a bundle of external cerebral ventricular drainage-associated ventriculitis control measures. DESIGN Clinical prospective case series. SETTING University Hospital of Larissa,(More)
Sepsis is a stressful physical condition, and at the acute phase, overstimulation of the sympathetic nervous system may occur; these events have the potential to induce cardiomyopathy. Takotsubo cardiomyopathy (TTC) is a form of catecholamine-induced cardiomyopathy, which occurs very rarely in sepsis. However, TTC management in critically ill patients with(More)
We evaluated whether prophylactic nebulised colistin could reduce ventilator-associated pneumonia (VAP) rates in an intensive care unit (ICU) setting with prevalent multidrug-resistant (MDR) bacteria.We used a single-centre, two-arm, randomised, open-label, controlled trial in a 12-bed ICU in the University Hospital of Larissa, Greece. Patient inclusion(More)
OBJECTIVE To identify risk factors for the first episode of Klebsiella Pneumonia resistant to carbapenems (KPRC) infection in critically ill patients. DESIGN, SETTING, AND METHODS This prospective cohort study was conducted in a 12-bed general Intensive Care Unit (ICU) in a University Hospital on ICU patients who required mechanical ventilation (MV) for(More)
OBJECTIVE To investigate prospectively the clinical course and risk factors for ventilator-associated tracheobronchitis (VAT) and the impact of VAT on intensive care unit (ICU) morbidity and mortality. DESIGN Prospective cohort study. SETTING University Hospital Larissa, Larissa, Greece. PATIENTS Critical care patients who received mechanical(More)
AIM To review available evidence for the role of adjunctive therapies in severe pneumonia. METHODS We focused on therapies that have attracted recently interest such as glucocorticosteroids (GCs), statins and recombinant activated protein-C. RESULTS Experimental animal and human studies showed that GCs are able to modulate the inflammatory response and(More)
MRSA infections, especially pneumonia have been associated with considerable morbidity and mortality and the management of MRSA infections is considered as an issue of high priority for scientific societies. Many studies which have been published during the last 10 years have provided evidence for MRSA pneumonia epidemiology, diagnosis and treatment. The(More)
Pneumonia, especially the more severe forms, is associated with considerable morbidity and mortality. Systemic use of antibiotics is the cornerstone of the management of pneumonia in all patients, including critical care patients. Several adjunctive strategies have been suggested to improve management. Notably, localized treatment in the lungs via the(More)
