Short-course daptomycin lock and systemic therapy for catheter-related bloodstream infections: a retrospective cohort study in cancer patients with surgically implanted devices.

Purpose: Few in vivo studies have been reported describing efficacy and duration of antibiotic lock therapy (ALT) with daptomycin (DPT) for long-term catheter-related bloodstream infections (CRBSI) due to coagulase-negative staphylococci (CoNS). We retrospectively analysed the efficacy of short-course ALT with DPT in combination with systemic treatment (ST) for CoNS-associated CRBSI in our hospital.

Methods: Patients admitted for CoNS-associated CRBSI and treated with DPT as ALT and ST were retrospectively analysed.

Prophylactic use of noninvasive ventilation in patients undergoing lung resectional surgery.

Question Of The Study: We studied whether prophylactic use of noninvasive pressure support ventilation (NIPSV) administered pre- and postoperatively may reduce the postoperative pulmonary function impairment.

Patients And Methods: Prospective randomized clinical trial. Thirty-nine patients with a preoperative FEV(1) <70% of the predicted value scheduled for elective lobectomy related to lung cancer were enrolled.

Constitutive expression of IL-2Rbeta chain and its effects on IL-2-induced vascular leak syndrome.

IL-2-induced vascular leak syndrome (VLS) is an important mechanism explaining the toxic effects of this cytokine and limiting its therapeutic use. We previously characterized a mouse model of IL-2-induced pulmonary VLS used to demonstrate that NK lymphocytes are involved in early/acute phase VLS (after one IL-2 injection). We also showed that NK cells and polymorphonuclear neutrophils (PMN) are involved in the late/chronic phase of the syndrome (after four daily IL-2 injections).

NK cells and polymorphonuclear neutrophils are both critical for IL-2-induced pulmonary vascular leak syndrome.

The mechanism of IL-2-induced vascular leak syndrome (VLS) is still poorly understood. Cells of both innate and adaptive immune systems have been implicated, but no definitive conclusions have been reached concerning their respective roles. In this study we report a new mouse model of IL-2-induced pulmonary VLS used to obtain a detailed analysis of the early events (sequestration of polymorphonuclear neutrophils and bronchoconstriction) and late events (modifications in the cell and protein content of bronchoalveolar lavages, followed by edema) that characterize this lung injury.
