Pharmacokinetics and Antifungal Activity of Echinocandins in Ascites Fluid of Critically Ill Patients.

The pharmacokinetics and antifungal activity of the echinocandins anidulafungin (AFG), micafungin (MFG), and caspofungin (CAS) were assessed in ascites fluid and plasma of critically ill adults treated for suspected or proven invasive candidiasis. Ascites fluid was obtained from ascites drains or during paracentesis. The antifungal activity of the echinocandins in ascites fluid was assessed by incubation of Candida albicans and Candida glabrata at concentrations of 0.

Penetration of echinocandins into wound secretion of critically ill patients.

Purpose: Wound infections caused by Candida are life-threatening and difficult to treat. Echinocandins are highly effective against Candida species and recommended for treatment of invasive candidiasis. As penetration of echinocandins into wounds is largely unknown, we measured the concentrations of the echinocandins anidulafungin (AFG), micafungin (MFG), and caspofungin (CAS) in wound secretion (WS) and in plasma of critically ill patients.

A high leukocyte count and administration of hydrocortisone hamper PCR-based diagnostics for bloodstream infections.

Bloodstream infections (BSIs) require an accurate and fast identification of causative pathogens. Molecular diagnostics, in particular polymerase chain reaction (PCR)-based approaches for BSI diagnostics directly from whole blood, suffer from limitations such as inhibition leading to invalid results. In this retrospective study, we analyzed 23 parameters for their potential interference with LightCycler SeptiFast PCR tests (n = 2167) routinely performed at our institution.

A Prospective Pilot Trial to Assess the Efficacy of Argatroban (Argatra) in Critically Ill Patients with Heparin Resistance.

The current study aims to evaluate whether prophylactic anticoagulation using argatroban or an increased dose of unfractionated heparin (UFH) is effective in achieving the targeted activated partial thromboplastin time (aPTT) of more than 45 s in critically ill heparin-resistant (HR) patients. Patients were randomized either to continue receiving an increased dose of UFH, or to be treated with argatroban. The endpoints were defined as achieving an aPTT target of more than 45 s at 7 h and 24 h.

Successful Resuscitation Using Extracorporeal Membrane Oxygenation of 2 Patients With Severe Liver Rupture: A Case Report.

Extracorporeal membrane oxygenation is a rescue treatment for respiratory or cardiac failure. Its use is limited in patients predisposed to bleeding due to heparin administration. We present 2 patients with deranged coagulation after liver rupture successfully treated by extracorporeal membrane oxygenation.

Acute coagulation disorder in a critically ill patient - A case report.

A 79-year-old critically ill woman presented with remarkable prolongation of activated partial thromboplastin time and thrombin time combined with high levels of anti-factor IIa activity 26 days after coronary artery bypass grafting. Coagulation disorder was associated with severe bleeding. Cause of coagulopathy was accidental administration of argatroban in an unknown dosage.

How Bispectral Index Compares to Spectral Entropy of the EEG and A-line ARX Index in the Same Patient.

Background: Bispectral index (BIS) monitoring of depth of anesthesia has pioneered the field for more recent monitoring devices like the A-line ARX Index (AAI) or the state (SE) and response entropy (RE) monitoring devices. Following an observational design the present study aimed to simultaneously compare in the same patient recorded BIS, AAI and entropy values.

Methods: Data from patients (n = 32) undergoing minor gynecological operations were analyzed.

Necrotizing fasciitis of the lower extremity caused by perforated sigmoid diverticulitis-a case report.

Diverticulosis of the sigmoid colon is a common condition and occurs more often in elderly patients. A well-known complication is infection or even perforation which often requires surgery. Necrotizing fasciitis as a complication of perforated diverticulitis is very rare.

Reversal of trauma-induced coagulopathy using first-line coagulation factor concentrates or fresh frozen plasma (RETIC): a single-centre, parallel-group, open-label, randomised trial.

Background: Effective treatment of trauma-induced coagulopathy is important; however, the optimal therapy is still not known. We aimed to compare the efficacy of first-line therapy using fresh frozen plasma (FFP) or coagulation factor concentrates (CFC) for the reversal of trauma-induced coagulopathy, the arising transfusion requirements, and consequently the development of multiple organ failure.

Methods: This single-centre, parallel-group, open-label, randomised trial was done at the Level 1 Trauma Center in Innsbruck Medical University Hospital (Innsbruck, Austria).

Nosocomial outbreak of extensively drug-resistant Pseudomonas aeruginosa associated with aromatherapy.

An increase of extensively drug-resistant Pseudomonas aeruginosa (XDR-PA) in various clinical specimens among intensive care unit patients (n = 7) initiated an outbreak investigation consisting of patient data analyses, control of adherence to infection control guidelines, microbiologic surveys, and molecular-based studies. XDR-PA was detected in a jointly used aroma-oil nursing bottle for aromatherapy. We implemented the restriction of oil sharing among patients.

Efficacy of argatroban in critically ill patients with heparin resistance: a retrospective analysis.

The patients who do not respond even to very high dosages of heparin are assumed to suffer from heparin resistance. The aim of this study was to investigate whether critically ill patients suffering from heparin resistance generally have low antithrombin III (AT) levels, and if the direct thrombin inhibitor argatroban in that case can be an effective option to achieve prophylactic anticoagulation. The study was conducted at the Department for General and Surgical Intensive Care Medicine at the University Hospital Innsbruck.

Histologic pathologies of the myocardium in septic shock: a prospective observational study.

Myocardial depression in septic shock is well known, but its pathophysiological genesis is incompletely understood. To assess the incidence and extent of stress-induced histologic myocardial alterations in septic shock, a prospective, observational, combined clinical and postmortem study was conducted, and 20 patients dying from septic shock were included. Exclusion criteria were younger than 18 years, pregnancy, open heart surgery or cardiopulmonary resuscitation, acute neurologic diseases, pheochromocytoma, and forensic autopsy.

Utility of PCR in diagnosis of invasive fungal infections: real-life data from a multicenter study.

Prospective studies addressing the clinical value of broad-range PCR using the internal transcribed spacer region (ITS) for diagnosis of microscopy-negative fungal infections in nonselected patient populations are lacking. We first assessed the diagnostic performance of ITS rRNA gene PCR compared with that of routine microscopic immunofluorescence examination. Second, we addressed prospectively the impact and clinical value of broad-range PCR for the diagnosis of infections using samples that tested negative by routine microscopy; the corresponding patients' data were evaluated by detailed medical record reviews.

Rapid detection of bloodstream pathogens by real-time PCR in patients with sepsis.

Rapid detection of bloodstream infections is an important issue for a better patient outcome. The aim of our study was thus to evaluate the LightCycler SeptiFast assay for diagnosis of bloodstream pathogens in a tertiary hospital in Western Austria. The 71 blood samples of 61 patients with presumed sepsis were investigated and compared with conventional blood culture system results.
