Randomized Controlled Trial Clinical Trial
The effects of IgM-enriched immunoglobulin preparations in patients with severe sepsis [ISRCTN28863830].
In this prospective, randomized controlled study, we aimed to evaluate the effect of IgM-enriched immunoglobulin treatment on progression of organ failure and septic shock in patients with severe sepsis. ⋯ Present data could not demonstrate any beneficial effects of polyclonal immunoglobulin preparation Pentaglobin on organ morbidity, septic shock incidence and mortality rate in patients with severe sepsis.

The ability of the isolated lung tissue to take up glucose and to release lactate is potentially similar to that of other body tissues. Nonetheless, when lung lactate exchange was assess in vivo in normal humans, no measurable lactate production could be detected. ⋯ Potential mechanisms of lactate production by the injured lung may include not only the onset of anaerobic metabolism in hypoxic zones, but also direct cytokine effects on pulmonary cells and an accelerated glucose metabolism in both the parenchymal and the inflammatory cells infiltrating lung tissue. In addition, as skeletal muscle, lung tissue may show metabolic adaptations in response to systemic mediators and may contribute to the systemic metabolic response to severe illness even in the absence of direct tissue abnormalities.
