Surprising Interactions Of Diabetes Mellitus And Sepsis


Drs. Annette Esper and Greg Martin from Emory University in Atlanta, Georgia worked with a team of researchers to investigate suspected links between diabetes mellitus (DM) and the likelihood of experiencing different kinds of organ dysfunction during sepsis. He said, "We've found that people with DM and sepsis were more likely to develop acute renal failure than people without DM, while being less likely to develop acute respiratory failure. Findings like these are important, as accurate identification of populations at risk for different acute organ dysfunctions is crucial to the development of novel therapies for these patients."

According to the Surviving Sepsis Campaign, it is estimated that 1,400 people die each day from sepsis. DM is an increasingly common illness, believed to afflict as much as 7% of the population of the US. The authors found that among patients with a respiratory source of sepsis, 16% of those with DM developed acute respiratory failure compared with 23% in people without DM. Among patients with a non-pulmonary source of sepsis, those with DM were still less likely to develop acute respiratory failure when compared with those without DM (6% vs. 10%).

Speculating upon possible reasons for the discrepancy, Martin said, "Possible mechanisms of protection in patients with DM may be impaired neutrophil function or altered neutrophil-endothelial interactions. Alternatively, patients with DM may be hospitalised earlier in the course of their illness than those with no DM because they learn to be aware of specific signs of infection. Finally, pharmacological aspects of DM care may also influence the development of organ dysfunction, because many medications administered to patients with DM, including insulin and thiazolidinediones, are known to have anti-inflammatory effects in addition to lowering blood glucose."
