The ideal management of infection includes not only the early identification and start of effective therapy but also the correct categorization of non-infected patients in order to avoid unnecessary use of antimicrobials. The availability of a specific and sensitive test for the presence of infection is of paramount importance to improve the prudent use of antimicrobial therapy. Procalcitonin (PCT) has been evaluated over recent years as to whether it can be used to detect the presence of different types of infection, allows reduced duration of antibiotic therapy, or predicts treatment failure or adverse outcome. In the previous issue of Critical Care, Jung and colleagues report about the monitoring of treatment response in abdominal sepsis by repetitive determination of PCT.

The pathophysiology of acute kidney injury (AKI) in sepsis is ill defined. We investigated parameters associated with low glomerular filtration, and their predictive value to discriminate transient from intrinsic septic AKI. ⋯ A low FENa and FEUrea is highly prevalent in the first hours of sepsis. In sepsis, oliguria is an earlier sign of impending AKI than increase in serum creatinine. A combination of a high FENa and a low FEUrea is associated with intrinsic AKI, whereas a combined high FENa and FEUrea is strongly predictive of transient AKI.

Observational Study
The effect of acute kidney injury on long-term health-related quality of life: a prospective follow-up study.
Acute kidney injury (AKI) is a serious complication in critically ill patients admitted to the Intensive Care Unit (ICU). We hypothesized that ICU survivors with AKI would have a worse health-related quality of life (HRQOL) outcome than ICU survivors without AKI. ⋯ The pre-admission HRQOL (by proxy) of AKI survivors was significantly lower in two dimensions compared with the age matched general population. Six months after ICU discharge survivors with and without AKI showed an almost similar HRQOL. However, compared with the general population with a similar age, HRQOL was poorer in both groups.

Glucocorticoid use in sepsis is controversial. In contrast to other extracellular signaling molecules, glucocorticoid receptors (GRs) are intra-cytoplasmic. ⋯ A study in Critical Care Forum suggests that sepsis alters the abundance of the dominant negative GRβ. Here we discuss GR isoforms and how they may affect cellular responses to glucocorticoids in sepsis.
