Multicenter Study
Immunoglobulins IgG1, IgM and IgA: a synergistic team influencing survival in sepsis.
The impact of endogenous immunoglobulin isotypes on the prognosis of patients with severe sepsis has not been sufficiently explored. The aim of this study was to evaluate the association between immunoglobulin levels in plasma and survival in patients with this condition. ⋯ The combined presence of low levels of the endogenous immunoglobulins IgG1, IgM and IgA in plasma is associated with reduced survival in patients with severe sepsis or septic shock. Assessment of the concentrations of these immunoglobulins could improve the results of treatment with exogenous immunoglobulins in patients with sepsis.

Patients with coronary artery disease who have prognostically significant lesions or symptoms despite optimum medical therapy require mechanical revascularization with coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI) or both. In this review, we will evaluate the evidence-based use of the two revascularization approaches in treating patients with coronary artery disease. CABG has been the predominant mode of revascularization for more than half a century and is the preferred strategy for patients with multivessel disease, especially those with diabetes mellitus, left ventricular systolic dysfunction or complex lesions. ⋯ Improvements in both CABG (including total arterial revascularization, off-pump CABG and 'no-touch' graft harvesting) and PCI (including newer-generation stents, adjunctive pharmacotherapy and intracoronary imaging) mean that they will continue to challenge each other in the future. A 'heart team' approach is strongly recommended to select an evidence-based, yet individualized, revascularization strategy for all patients with complex coronary artery disease. Finally, optimal medical therapy is important for all patients with coronary artery disease, regardless of the mode of revascularization.

Maintaining normoglycaemia not only reduces the risk of diabetic microvascular complications but also corrects the metabolic abnormalities that contribute to the development and progression of hyperglycaemia, that is insulin resistance and beta-cell dysfunction. Progressive beta-cell failure, in addition to side effects associated with many current antidiabetic agents, for example hypoglycaemia and weight gain, presents major obstacles to the achievement of the recommended goal of glycaemic control in patients with type 2 diabetes mellitus (T2DM). ⋯ Because of the iR unique mechanism of action, which is independent of insulin secretion and insulin action, these agents are effective in lowering the plasma glucose concentration in all stages of the disease and can be combined with all other antidiabetic agents. In this review, we will summarize the available data concerning the mechanism of action, efficacy and safety of this novel class of antidiabetic agents.

Urokinase-type plasminogen activator receptor (uPAR) is upregulated during inflammation and known to bind to β3 -integrins, receptors used by pathogenic hantaviruses to enter endothelial cells. It has been proposed that soluble uPAR (suPAR) is a circulating factor that causes focal segmental glomerulosclerosis and proteinuria by activating β3 -integrin in kidney podocytes. Proteinuria is also a characteristic feature of hantavirus infections. The aim of this study was to evaluate the relation between urine suPAR levels and disease severity in acute Puumala hantavirus (PUUV) infection. ⋯ Urinary suPAR is markedly increased during acute PUUV infection and is correlated with proteinuria. High urine suPAR level may reflect local production of suPAR in the kidney during the acute infection.

The aim of this study was to combine clinical criteria and next-generation sequencing (pyrosequencing) to establish a diagnosis of familial hypercholesterolaemia (FH). ⋯ Using a combination of clinical criteria and targeted next-generation sequencing, we have achieved FH diagnosis with a high success rate. Furthermore, we identified a new splicing-site mutation in the LDLR gene.
