Severe sepsis and septic shock are common complications in the intensive care unit and associated with high mortality. Early antimicrobial therapies together with organ-supportive measures are the major therapeutic approaches. However in the last decades immunmodulatory therapies have been investigated due to the notion of a compromised inflammatory response in septic patients. In addition to lowering circulating cholesterol, statins (HMG-CoA-reductase- inhibitors) have also been shown to possess pleiotropic anti-inflammatory potential. Recent studies indicate that these anti-inflammatory effects also modulate acute inflammatory response and therefore may play a protective role in septic patients. In this review, the pathophysiological backround and first clinical trials of statins as a new adjuvant therapy in sepsis are summarized. © Georg Thieme Verlag KG Stuttgart.

The role of procalcitonin (PCT) plasma levels as a diagnostic tool for intensive care patients has been intensively investigated during the past years. In particular for recognition of bacterial infections, PCT levels have been shown to be superior to other clinical and biochemical markers. Furthermore, some very recent studies show that in patients with lower respiratory tract infections PCT guided antibiotic therapy reduces antibiotic use and thereby may also reduce duration of stay of patients in hospital and thus cut hospitalisation costs. However, various studies indicate that the value of PCT as a prognostic marker is limited because of false positive or negative values. Despite these limitations PCT plasma levels are currently measured in intensive care units. The present study summarises the possible clinical uses of this lab marker as a diagnostic tool for the assessment of critically of ill patients. © 2011 by Walter de Gruyter.

In 1985 interleukin 6 (IL-6) was first identified as a differentiation factor for B-cells (B-cell stimulatory factor 2) which caused B-cells to mature and produce antibodies. Numerous studies now demonstrate the pleiotropic character of IL-6, which has been shown to possess important functions in the immune system, the regulation of hematopoesis, inflammation and oncogenesis. In the central nervous system (CNS), IL-6 is involved in neurogenesis and the response of neurons and glia-cells to various injuries. CNS infections, cerebral ischaemia, CNS traumata or chronic inflammatory diseases with CNS manifestations such as neuro-lupus or neuro-sarcoidosis are associated with increased IL-6 levels in the cerebrospinal fluid (CSF). Thus, the use of IL-6 as a diagnostic and prognostic tool in these diseases is being investigated. In this review we aim to provide an overview of current studies and evaluate the diagnostic significance of CSF-IL-6. © 2015 by De Gruyter.

C-reactive protein (CRP) currently constitutes one of the most widely used parameters for the diagnosis of infections and inflammatory processes, due to simple methods and low costs. However, in recent years, other parameters, such as interleukin 6 (IL-6) and procalcitonin (PCT), have gained in importance. Although these parameters are presently not established everywhere in clinical routine, they provide significant advantages in the diagnosis and monitoring of inflammatory diseases. For instance, in intensive care, the increase in IL-6 levels may indicate inflammatory complications 24 to 48 h prior to the increase in circulating CRP levels. In contrast to CRP, PCT shows a higher specificity for bacterial infections, which facilitates the diagnosis of bacterial infections and sepsis. Therefore, PCT values provide a better evaluation of prognosis and therapeutic success and of a necessary change in therapy. These points raise the question whether CRP levels should at least in part be replaced by PCT and/or IL-6. Thus, this review seeks to examine the value of CRP in relation to PCT and IL-6 in the diagnosis of bacterial infections, in therapeutic monitoring, and regarding prognosis in critical care patients. © 2013 by Walter de Gruyter Berlin Boston 2013.
