Abstract
Pleural space infections have been a well-recognized clinical syndrome for over 4000
years and continue to cause significant morbidity and mortality worldwide. However,
our collective understanding of the causative pathophysiology has greatly expanded
over the last few decades, as have our treatment options. The aim of this paper is
to review recent updates in our understanding of this troublesome disease and to provide
updates on established and emerging treatment modalities for patients suffering from
pleural space infections. With that, we present a review and discussion synthesizing
the recent pertinent literature surrounding the history, epidemiology, pathophysiology,
diagnosis, and management of these challenging infections.
Background: This document provides evidence-based clinical practice guidelines on the management of adult patients with community-acquired pneumonia. Methods: A multidisciplinary panel conducted pragmatic systematic reviews of the relevant research and applied Grading of Recommendations, Assessment, Development, and Evaluation methodology for clinical recommendations. Results: The panel addressed 16 specific areas for recommendations spanning questions of diagnostic testing, determination of site of care, selection of initial empiric antibiotic therapy, and subsequent management decisions. Although some recommendations remain unchanged from the 2007 guideline, the availability of results from new therapeutic trials and epidemiological investigations led to revised recommendations for empiric treatment strategies and additional management decisions. Conclusions: The panel formulated and provided the rationale for recommendations on selected diagnostic and treatment strategies for adult patients with community-acquired pneumonia.
Intrapleural fibrinolytic agents are used in the drainage of infected pleural-fluid collections. This use is based on small trials that did not have the statistical power to evaluate accurately important clinical outcomes, including safety. We conducted a trial to clarify the therapeutic role of intrapleural streptokinase. In this double-blind trial, 454 patients with pleural infection (defined by the presence of purulent pleural fluid or pleural fluid with a pH below 7.2 with signs of infection or by proven bacterial invasion of the pleural space) were randomly assigned to receive either intrapleural streptokinase (250,000 IU twice daily for three days) or placebo. Patients received antibiotics and underwent chest-tube drainage, surgery, and other treatment as part of routine care. The number of patients in the two groups who had died or needed surgical drainage at three months was compared (the primary end point); secondary end points were the rates of death and of surgery (analyzed separately), the radiographic outcome, and the length of the hospital stay. The groups were well matched at baseline. Among the 427 patients who received streptokinase or placebo, there was no significant difference between the groups in the proportion of patients who died or needed surgery (with streptokinase: 64 of 206 patients [31 percent]; with placebo: 60 of 221 [27 percent]; relative risk, 1.14 [95 percent confidence interval, 0.85 to 1.54; P=0.43), a result that excluded a clinically significant benefit of streptokinase. There was no benefit to streptokinase in terms of mortality, rate of surgery, radiographic outcomes, or length of the hospital stay. Serious adverse events (chest pain, fever, or allergy) were more common with streptokinase (7 percent, vs. 3 percent with placebo; relative risk, 2.49 [95 percent confidence interval, 0.98 to 6.36]; P=0.08). The intrapleural administration of streptokinase does not improve mortality, the rate of surgery, or the length of the hospital stay among patients with pleural infection.
