Our study showed that PE is common in patients with severe COPD exacerbation requiring ICU admission. Moreover, PE was significantly associated with higher mortality and ICU LOS in critically ill patients with severe COPD exacerbation.

TXA is an interesting treatment in haemorrhagic shock. Its efficiency in head trauma is still debated and controversial. Its impact on the mortality and the needs of transfusion or surgery were not demonstrated in this study. Nevertheless, its safety worth to be studied in larger samples as we found a higher rate of pulmonary embolism in the treated group.

A. baumannii VAP is associated with a high mortality. Hemodynamic impairment is predictive of a poor outcome.

The SChE activity level was significantly decreased in patients with septic shock. However, its prognostic value is poor. Our results suggest that SChE activity is useful for the diagnosis of septic shock. Further studies are warranted to confirm our findings.

Yarrowia lipolytica is weakly pathogenic yeast, which is rarely isolated from the blood. We report unusual cases of Y. lipolytica fungemia occurred between October 2012 and June 2014 in the intensive care unit (ICU) of the UH Habib Bourguiba Sfax. During this period, 55 cases of Y. lipolytica septicemia were diagnosed. There were 44 men and 11 women (sex ratio = 4).The median age was 43 years. The broad-spectrum antibiotics (100 %), the catheterization (96 %), and the prolonged hospitalization in ICU (91 %) were the main risk factors. Patients were hospitalized in ICU, mostly, for polytraumatism (45.4 %), pneumopathy (9 %), and post-operative complications (7 %). Fever unresponsive to broad-spectrum antibacterial therapy was the predominant sign of infection (83.6 %). Y. lipolytica was isolated in one or several blood cultures (14.5 %) and in the catheter tip culture of nine patients (16.3 %).Treatment was based on intravenous amphotericin B (58.2 %), fluconazole (45.4 %) and/or removal catheter (69 %). Apyrexia or blood cultures sterilization was obtained for 34 patients (61.8 %). Y. lipolytica candidemia is an opportunistic and emerging human yeast pathogen. It can reach to the bloodstream of immunocompromised or critically ill patients during hospitalization through intravascular catheterization. Further clinical data need to be evaluated for formulating management strategies of seriously ill patients infected with uncommon fungal agents.
