A recent survey conducted by the publicly funded Competence Network Sepsis (SepNet) reveals that severe sepsis and/or septic shock occurs in 75,000 inhabitants (110 out of 100,000) and sepsis in 79,000 inhabitants (116 out of 100,000) in Germany annually. This illness is responsible for approximately 60,000 deaths and ranges as the third most frequent cause of death after acute myocardial infarction. Direct costs for the intensive care of patients with severe sepsis alone amount to approximately 1.77 billion euros, which means that about 30% of the budget in intensive care is used to treat severe sepsis. However, until now German guidelines for the diagnosis and therapy of severe sepsis did not exist. Therefore, the German Sepsis Society initiated the development of guidelines which are based on international recommendations by the International Sepsis Forum (ISF) and the Surviving Sepsis Campaign (SSC) and take into account the structure and organization of the German health care system. Priority was given to the following guideline topics: a) diagnosis, b) prevention, c) causative therapy, d) supportive therapy, e) adjunctive therapy. The guidelines development process was carefully planned and strictly adhered to the requirements of the Working Group of Scientific Medical Societies (AWMF).

Left ventricular end diastolic (LVEDP) and mean right atrial (RAP) pressures were recorded simultaneously in 30 patients with shock (14 acute myocardial infarction, 10 acute pulmonary embolism or severe bronchopulmonary disease, and 6 sepsis). Myocardial infarction was characterized by a predominant increase in LVEDP, pulmonary disease by a predominant increase in RAP, and sepsis by a normal relationship between LVEDP and RAP. In all three groups a significant positive correlation was noted between RAP and LVEDP, with the regression line in cor pulmonale deviated significantly toward the RAP axis and the regression line in myocardial infarction exhibiting a zero RAP intercept at an elevated LVEDP.Low cardiac outputs with elevated LVEDP in myocardial infarction indicated severe left ventricular failure. Low outputs with elevated RAP in cor pulmonale were consistent with right ventricular overload. Although cardiac outputs often were normal in sepsis, low outputs with elevated cardiac filling pressures in some patients were consistent with a hemodynamic or humoral-induced generalized depression of cardiac performance.Vasoconstrictor and inotropic drugs often produced a functional disparity between the two ventricles, with the gradient between LVEDP and RAP increasing, apparently because of an increase in left ventricular work or an inadequacy of left ventricular oxygen delivery. Acute plasma volume expansion with dextran in patients with pulmonary vascular disease resulted in a somewhat more rapid rise in RAP than in LVEDP. In septic and myocardial infarction shock, however, LVEDP and RAP usually rose proportionally, with the absolute rise of LVEDP surpassing that of RAP. Although the absolute level of the central venous pressure thus may not be a reliable indicator of left ventricular function in shock, changes in venous pressure during acute plasma volume expansion should serve as a fairly safe guide to changes in LVEDP.

Severe sepsis and septic shock are as common and lethal as other acute life-threatening conditions that emergency physicians routinely confront such as acute myocardial infarction, stroke, and trauma. Recent studies have led to a better understanding of the pathogenic mechanisms and the development of new or newly applied therapies. These therapies place early and aggressive management of severe sepsis and septic shock as integral to improving outcome. This independent review of the literature examines the recent pathogenic, diagnostic, and therapeutic advances in severe sepsis and septic shock for adults, with particular relevance to emergency practice. Recommendations are provided for therapies that have been shown to improve outcomes, including early goal-directed therapy, early and appropriate antimicrobials, source control, recombinant human activated protein C, corticosteroids, and low tidal volume mechanical ventilation.

We analyzed survival rates of 144 prevalent patients on maintenance hemodialysis from 1998 to 2003 at the Department of Nephrology and Dialysis, Rijeka University Hospital, Rijeka, Croatia, and evaluated risk factors predicting their survival. Included were only end-stage renal disease (ESRD) patients on maintenance hemodialysis treatment dialysed more than 6 months before entering the study and who were clinically stable. The patients were randomised in two groups according to the presence or absence of diabetic nephropathy as the cause of ESRD and followed-up. The patient's death as outcome measure was recorded. The survival rates were estimated by the Kaplan-Meier method. The major causes of death were cardiovascular disease in 40 (60.6%) patients. An acute myocardial infarction in 15 (22.7%) patients was the major single cause of death. We found a significantly lower survival of diabetic patients than non-diabetic patients (P=0.0013). The most important predictors of death among diabetic patients on maintenance hemodialysis were hyperglycaemia (P<0.001), ischemic heart disease (P=0.004), hypercholesterolemia (P=0.013), and low delivered dialysis dose (P=0.013). The survival of diabetic patients undergoing hemodialysis was much worse than survival of non-diabetic patients. The cardiovascular disease remained the major cause of death in both groups. Early detection of pre-existing cardiovascular risk factors and diseases, and treatment of infections leading to sepsis, are of great importance, as they may influence the survival rates. Intensive management of diabetic patients is essential.

Although multiple studies of acute myocardial infarction, trauma, and stroke have been translated into improved outcomes by applying diagnosis and therapy at the most proximal stage of hospital presentation (before intensive care unit arrival), this approach to the sepsis patient has been lacking. In response to this, a trial comparing early goal-directed therapy (EGDT) versus standard care was performed using internally and externally validated criteria for early identification of high risk patients, established definitions, and a consensus-derived protocol to reverse the hemodynamic perturbations of hypovolemia, vasoregulation, myocardial suppression and increased metabolic demands. That trial of EGDT resulted in significant reductions in morbidity, mortality, vasopressor use, and health care resource consumption. The end-points used in the protocol and the outcome results were subsequently externally validated, revealing similar or better mortality benefit. This commentary examines the rational and validation for the use of early markers of illness severity. Current evidence support the endpoints in the EGDT protocol, external validity in regards to outcome benefit and the universal need to improve the quality of care for early sepsis.

Studies of acute myocardial infarction, trauma, and stroke have been translated into improved outcomes by earlier diagnosis and application of therapy at the most proximal stage of hospital presentation. Most therapies for these diseases are instituted prior to admission to an ICU; this approach to the sepsis patient has been lacking. In response, a trial comparing early goal-directed therapy (EGDT) vs standard care was performed using specific criteria for the early identification of high-risk sepsis patients, verified definitions, and a consensus-derived protocol to reverse the hemodynamic perturbations of hypovolemia, vasoregulation, myocardial suppression, and increased metabolic demands. Five years after the EGDT publication, there has been much discussion generated with regard to the concepts of EGDT, as well as debate fueled regarding diagnostic and therapeutic interventions. However, during this time period further investigations by the primary investigators and others have brought additional contemporary findings. EGDT modulates some of the components of inflammation, as reflected by improved organ function. The end points used in the EGDT protocol, the outcome results, and the cost-effectiveness have subsequently been externally validated, revealing similar or even better findings than those from the original trial. Although EGDT is faced with challenges, a coordinated approach to sepsis management is necessary to duplicate the progress in outcomes seen in patients with conditions such as acute myocardial infarction, stroke, and trauma.

Calciphylaxis is a rare condition with a high mortality involving mural calcification of small vessels and occurring primarily in patients with end-stage renal disease. Most cases are characterized by rapid progression of tender subcutaneous nodules or cutaneous plaques to epidermal necrosis, with death in the majority of cases occurring from sepsis. The condition is still poorly understood and the pathogenesis not known. We report a case of calciphylaxis following an unusually benign course. Our patient was a 63-year-old Chinese woman with end-stage renal failure undergoing peritoneal dialysis who presented with itchy pruriginous rashes on her limbs and trunk with subsequent development of eschars and ulceration. Biopsy confirmed the presence of calcification within vessel walls in the subcutis. She was managed conservatively and refused a parathyroidectomy. Surprisingly, her disease did not worsen but remained stable. She died from an acute myocardial infarction 5 months after presenting to our clinic.

We sought to assess the microbiologic profile of patients with suspected sepsis who participated in the SHould we emergently revascularize Occluded Coronaries in cardiogenic shocK? (SHOCK) trial, a randomized controlled trial of early coronary revascularization in patients with cardiogenic shock complicating acute myocardial infarction. A protocol-mandated SEPSIS form was completed prospectively for 54 patients (18%) with fever or leukocytosis suggestive of sepsis. These patients were divided further into those with positive (n = 40) or negative (n = 14) culture results. The predominant pathogen isolated in patients with positive culture results was Staphylococcus aureus (32%), followed by Klebsiella pneumoniae and Pseudomonas aeruginosa. Patients with both positive and negative culture results had longer median durations of mechanical ventilation (p <0.001 and p = 0.02), intra-aortic balloon pump (IABP) support (p = 0.074 and p = 0.021), and hospital stay (p <0.001 and p = 0.048) than controls. Sepsis was predicted by both duration of IABP support (p = 0.007) and use of multiple central catheters (p = 0.026). In conclusion, clinical sepsis is common after cardiogenic shock complicating acute myocardial infarction, particularly in patients who received prolonged IABP support or had multiple central catheters.
