Serum inflammatory and brain injury biomarkers in COVID-19 patients admitted to intensive care unit: A pilot study.

Background: The aim of this study was to measure serum brain injury biomarkers in patients with COVID-19 admitted to intensive care unit (ICU), without evidence of brain impairment, and to determine potential correlations with systemic inflammatory markers, illness severity, and outcome.

Methods: In patients admitted to the ICU with COVID-19, without clinical evidence of brain injury, blood S100 calcium-binding protein B (S100B), neuron-specific enolase (NSE) and interleukin-6 (IL-6) were measured on admission. Clinical, routine laboratory data and illness severity were recorded.

Older adults with severe coronavirus disease 2019 admitted to intensive care unit: prevalence, characteristics and risk factors for mortality.

Background: Although older adults are at high risk for severe coronavirus disease 2019 (COVID-19) requiring intensive care unit (ICU) admission, age is often used as a selection criterion in case of ICU beds scarcity. We sought to compare the proportion, clinical features and mortality between patients ≥70 years old and younger ICU patients with COVID-19.

Methods: All patients, consecutively admitted to our COVID ICU, where age was not used as an admission criterion, from March 2020 through April 2021, were included.

Hospital Resources May Be an Important Aspect of Mortality Rate among Critically Ill Patients with COVID-19: The Paradigm of Greece.

For critically ill patients with coronavirus disease 2019 (COVID-19) who require intensive care unit (ICU) admission, extremely high mortality rates (even 97%) have been reported. We hypothesized that overburdened hospital resources by the extent of the pandemic rather than the disease per se might play an important role on unfavorable prognosis. We sought to determine the outcome of such patients admitted to the general ICUs of a hospital with sufficient resources.

Lactate Kinetics Reflect Organ Dysfunction and Are Associated with Adverse Outcomes in Intensive Care Unit Patients with COVID-19 Pneumonia: Preliminary Results from a GREEK Single-Centre Study.

Coronavirus disease-19 (COVID-19) continues to be a health threat worldwide. Increased blood lactate is common in intensive care unit (ICU) patients; however, its association with outcomes in ICU COVID-19 patients remains currently unexplored. In this retrospective, observational study we assessed whether lactate is associated with outcomes in COVID-19 patients.

Effect of clarithromycin in patients with sepsis and ventilator-associated pneumonia.

Background: Because clarithromycin provided beneficiary nonantibiotic effects in experimental studies, its efficacy was tested in patients with sepsis and ventilator-associated pneumonia (VAP).

Methods: Two hundred patients with sepsis and VAP were enrolled in a double-blind, randomized, multicenter trial from June 2004 until November 2005. Clarithromycin (1 g) was administered intravenously once daily for 3 consecutive days in 100 patients; another 100 patients were treated with placebo.

Early apoptosis of blood monocytes in the septic host: is it a mechanism of protection in the event of septic shock?

Introduction: Based on the central role of the triggering of monocytes for the initiation of the septic cascade, it was investigated whether apoptosis of blood monocytes in septic patients is connected to their final outcome.

Methods: Blood monocytes were isolated from 90 patients with septic syndrome due to ventilator-associated pneumonia on days 1, 3, 5 and 7 from the initiation of symptoms. Apoptosis was defined after incubation with annexin-V-fluorescein isothiocyanate and propidium iodine and reading by a flow cytometer.

Anuria due to acute bilateral renal vein occlusion after thrombolysis for pulmonary embolism.

Severe hemorrhage is the more frequent complication of thrombolysis, with intracranial bleeding the most critical one. We report a 73-year-old woman with major pulmonary embolism (PE), yet haemodynamically stable, in whom thrombolysis resulted in severe complications with acute renal failure (ARF) due to bilateral renal vein occlusion, quite unexpected; this complication has never been reported, as yet. We believe that disrupture of peripheral vein clots by thrombolysis led to migration of thrombi particles upwards to the inferior vena cava (IVC) and bilateral renal vein occlusion.
