  • Insulin increases the release of proinflammatory mediators JOURNAL OF TRAUMA-INJURY INFECTION AND CRITICAL CARE Brundage, S. I., Kirilcuk, N. N., Lam, J. C., Spain, D. A., Zautke, N. A. 2008; 65 (2): 367-372

    Abstract

    Strict glucose control with insulin is associated with decreased mortality in a mixed patient population in the intensive care unit. Controversy exists regarding the relative benefits of glucose control versus a direct advantageous effect of exogenous insulin. As a combined medical/surgical population differs significantly from the critically injured patient primed for secondary insult, our purpose was to determine the influence of insulin on activated macrophages. Our hypothesis was that insulin would directly abrogate the inflammatory cascade.Differentiated human monocytic THP-1 cells were stimulated with endotoxin (lipopolysaccharide [LPS], 100 ng/mL) for 6 hours. Cells were treated +/-10(-7) M insulin for 1 hour and 24 hours. Total RNA was isolated and gene expression for TNF-alpha and IL-6 performed using Q-RT-PCR. Supernatants were assayed for TNF-alpha and IL-6 protein by ELISA.At 1 hour, compared with macrophages treated with LPS alone, macrophages treated with insulin produced significantly more TNF-alpha protein (11.4 +/- 5.9 pg/mL vs. 32.5 +/- 3.1 pg/mL; p < 0.03). At 24 hours compared with macrophages treated with LPS alone, macrophages treated with insulin produced significantly more TNF-alpha protein (83 +/- 2.02 pg/mL vs. 114 +/- 6.54 pg/mL; p < 0.01). However, gene expression of TNF-alpha and IL-6 was not different in LPS stimulated macrophages with and without insulin treatment at both 1 hour and 24 hours.Contrary to our hypothesis, insulin does not have direct anti-inflammatory properties in this experimental model. In fact, insulin increases proinflammatory cytokine protein levels from activated macrophages.

  • Are temporary inferior vena cava filters really temporary? AMERICAN JOURNAL OF SURGERY Kirilcuk, N. N., Herget, E. J., Dicker, R. A., Spain, D. A., Hellinger, J. C., Brundage, S. I. 2005; 190 (6): 858-863

    Abstract

    Despite significant risk for venous thromboembolism, severely injured trauma patients often are not candidates for prophylaxis or treatment with anticoagulation. Long-term inferior vena cava (IVC) filters are associated with increased risk of postphlebitic syndrome. Retrievable IVC filters potentially offer a better solution, but only if the filter is removed; our hypothesis is that the most of them are not.This retrospective study queried a level I trauma registry for IVC filter insertion from September 1997 through June 2004.One IVC filter was placed before the availability of retrievable filters in 2001. Since 2001, 27 filters have been placed, indicating a change in practice patterns. Filters were placed for prophylaxis (n = 11) or for therapy in patients with pulmonary embolism or deep vein thrombosis (n = 17). Of 23 temporary filters, only 8 (35%) were removed.Surgeons must critically evaluate indications for IVC filter insertion, develop standard criteria for placement, and implement protocols to ensure timely removal of temporary IVC filters.
