The use of high-dose corticosteroids in the treatment severe sepsis and septic shock remains controversial. Our study was designed as a prospective, randomized, double-blind, placebo-controlled trial methylprednisolone sodium succinate for shock. Diagnosis based on clinical suspicion infection plus presence fever or hypothermia (rectal temperature >38.3°C [101°F] <35.6°C [96°F]), tachypnea (>20 breaths per minute), tachycardia (>90 beats one following indications organ dysfunction: change...

Recent trials suggest procalcitonin-based guidelines can reduce antibiotic use for respiratory infections. However, the accuracy of procalcitonin to discriminate between viral and bacterial pneumonia requires further dissection. We evaluated association serum concentration at hospital admission with pathogens detected in a multicenter prospective surveillance study adults hospitalized community-acquired pneumonia. Systematic pathogen testing included cultures, serology, urine antigen tests,...

A disruption of the crosstalk between gut and lung has been implicated as a driver severity during respiratory-related diseases. Lung injury causes systemic inflammation, which disrupts barrier integrity, increasing permeability to microbes their products. This exacerbates resulting in positive feedback. We aimed test whether severe Coronavirus disease 2019 (COVID-19) is associated with markers disrupted permeability. applied multi-omic systems biology approach analyze plasma samples from...
