REVIEW
Katharina Rump, Michael Adamzik
Background: Sepsis is a common cause of death in intensive care units worldwide. Due to the high complexity of this immunological syndrome development of novel therapeutic strategies is urgent. Promising drug targets or biomarkers may depict aquaporins (AQPs) as they regulate crucial key mechanisms of sepsis. Main body: Here we report on base of the current literature that several AQPs are involved in different physiological processes of sepsis. In immune system mainly AQPs 3, 5 and 9 seem to be important, as they regulate the migration of different immune cells...

BACKGROUND: The development of sensitive myocardial-specific cardiac biomarkers allows for detection of very small amounts of myocardial injury or necrosis. Myocardial injury (MI) as a prelude of the serious perioperative complication myocardial infarction, should be paid more attention, especially in elderly susceptible patients. Myocardial injury after abdominal surgery in elderly patients has not been described yet. The objectives of this study were to identify the incidence, predictors, characteristics and the impact of MI on outcome in elderly patients underwent abdominal surgery...

The purpose of this study was to confirm the prognostic value of pentraxin-3 (PTX3), procalcitonin (PCT) and lactate in patients with severe infections requiring ICU management and to develop and validate a model to enhance mortality prediction by combining severity scores with biomarkers. We included 141 patients with the diagnosis of sepsis/septic shock. The levels of PTX3, PCT and lactate were measured on day 0, 3, 7 of hospitalization and Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were also evaluated...

OBJECTIVES: Methotrexate (MTX) is the anchor drug for treatment of rheumatoid arthritis (RA), but the mechanism of its anti-inflammatory action is not fully understood. In RA, macrophages display a proinflammatory polarisation profile that resembles granulocyte-macrophage colony-stimulating factor (GM-CSF)-differentiated macrophages and the response to MTX is only observed in thymidylate synthase+ GM-CSF-dependent macrophages. To determine the molecular basis for the MTX anti-inflammatory action, we explored toll-like receptor (TLR), RA synovial fluid (RASF) and tumour necrosis factor receptor (TNFR)-initiated signalling in MTX-exposed GM-CSF-primed macrophages...

In sepsis, trauma and major surgery, where an explicit physiological insult leads to a significant systemic inflammatory response, the acute evolution of biomarkers have been delineated. In these settings, Interleukin (IL) -6 and TNF-α are often the first pro-inflammatory markers to rise, stimulating production of acute phase proteins followed by peaks in anti-inflammatory markers. Patients undergoing SPKT as a result of diabetic complications already have an inflammatory phenotype as a result of uraemia and glycaemia...

BACKGROUND: Sepsis-associated hyperlactatemia is a widely used biomarker, associated with initial severity and poor outcomes. This increased circulating lactate concentration has been proposed to result in part from a mismatch between oxygen delivery and demand in organs. However, other mechanisms may participate. In particular, a metabolic reprogramming similar to the Warburg effect initially described in cancer cells could lead to increased lactate production by immune cells such as T lymphocytes after sepsis...

PURPOSE: To explore potential design for pharmacogenomics trials in sepsis, we investigate the interaction between pharmacogenomic biomarkers and response to drotrecogin alfa (activated) (DrotAA). This trial was designed to validate whether previously identified improved response polymorphisms (IRPs A and B) were associated with an improved response to DrotAA in severe sepsis. METHODS: Patients with severe sepsis at high risk of death, who received DrotAA or not, with DNA available were included and matched to controls adjusting for age, APACHE II or SAPS II, organ dysfunction, ventilation, medical/surgical status, infection site, and propensity score (probability that a patient would have received DrotAA given their baseline characteristics)...

Sepsis is a leading cause of mortality. This study aims to assess the utility of the soluble mannose receptor (sMR) as a biomarker of sepsis and mortality in patients hospitalized with suspected infection. Using an in-house ELISA assay the concentration of sMR was analyzed in the serum of patients from three prospective studies. Using Sepsis-3 guidelines, patients were stratified as no infection (NI, n = 68), verified infection without sepsis (NSEP, n = 133) and verified infection with sepsis (SEP, n = 190)...

Assessment of intracranial vessels includes transcranial Doppler (TCD). TCD performance requires intact temporal acoustic windows (TAW). Failure of TAW (TAWF) is present in 8-20% of people. There have been no reports on TAWF in rheumatoid arthritis (RA). Altogether, 62 female RA patients were included. Among them, 20 were MTX-treated and biologic-free, 20 received infliximab, and 22 tocilizumab. The controls included 60 non-RA women. TAWF, temporal bone thickness, and texture were determined by ultrasound and CT...

BACKGROUND C-reactive protein (CRP) is an important biomarker of sepsis. Several single-nucleotide polymorphisms (SNPs) in the CRP gene can determine plasma CRP levels and are risk factors in many diseases, such as cancer, arteritis, and diabetes. However, it is unknown whether polymorphisms in CRP are associated with susceptibility to and outcome of infantile sepsis. We explored the effect of these SNPs on CRP response in infantile sepsis, and compared genetic data on patients with sepsis. MATERIAL AND METHODS A total of 49 infants with sepsis and 20 healthy infants were enrolled during hospitalization, and 3 SNPs in the CRP gene region (rs1205, rs2808530, and rs3091244) were genotyped and then analyzed for associations with CRP levels and sepsis...

BACKGROUND: Procalcitonin (PCT) is a serum biomarker currently suggested by the Surviving Sepsis Campaign to aid in determination of the appropriate duration of therapy in sepsis patients. We review the use of procalcitonin in patients after trauma or acute care surgery. METHOD: A MEDLINE search via PubMed was performed using the combination of "procalcitonin" and "humans" and "injuries, trauma," "wounds and injuries," or "wounds." Studies of burn patients, children, other biomarkers, and non-acute care surgery were excluded...

Acute kidney injury (AKI) is a heterogeneous clinical syndrome that has multiple aetiologies, variable pathogenesis and diverse outcomes. However, these heterogeneities are not reflected in current approaches to the diagnosis and, to some degree, treatment of AKI. For example, congestive heart failure and dehydration can produce identical changes in serum creatinine level and urine output (parameters that are used to define AKI); however, they differ vastly in their physiological contexts and demand completely opposite treatments...

PURPOSE OF REVIEW: Sepsis and septic shock are prevalent conditions that are likely to increase in prevalence in the future. Given the high mortality and morbidity associated with sepsis and sepsis-induced cardiac dysfunction, we must continue to make advances in knowledge of the complex physiologic interactions and how we may target specific mediators for potential therapeutic options in the future. RECENT FINDINGS: Multiple biomarkers have been discovered, which when assayed in sepsis-induced cardiomyopathy predict morbidity and mortality...

BACKGROUND: Statins can exert pleiotropic anti-inflammatory, vascular protective and anticoagulant effects, which in theory could improve the dysregulated host response during sepsis. We aimed to determine the association between prior statin use and host response characteristics in critically ill patients with sepsis. METHODS: We performed a prospective observational study in 1060 patients admitted with sepsis to the mixed intensive care units (ICUs) of two hospitals in the Netherlands between January 2011 and July 2013...

Burn patients are susceptible to infections due, in part, to immune dysfunction. Upregulation of programmed death-1 (PD-1) receptor on T cells and programmed cell death ligand-1 (PD-L1) on myeloid cells contribute to immune dysfunction in nonburn-related sepsis. We hypothesized that PD-1/PDL1 interactions contribute to immune dysfunction after burn injury. To determine the impact of burn injury and infection on PD-L1, PD-1 and costimulatory receptor expression by leukocytes and its relationship to T cell functions...
