Background Hyperglycemia and insulin resistance are common in critically ill patients, even if they have not previously had diabetes. Whether the normalization of blood glucose levels with insulin therapy improves the prognosis for such patients is not known. Methods We performed a prospective, randomized, controlled study involving adults admitted to our surgical intensive care unit who were receiving mechanical ventilation. On admission, patients were randomly assigned to receive intensive insulin therapy (maintenance of blood glucose at a level between 80 and 110 mg per deciliter) or conventional treatment (infusion of insulin only if the blood glucose level exceeded 215 mg per deciliter and maintenance of glucose at a level between 180 and 200 mg per deciliter). Results At 12 months, with a total of 1548 patients enrolled, intensive insulin therapy reduced mortality during intensive care from 8.0 percent with conventional treatment to 4.6 percent (P<0.04, with adjustment for sequential analyses).

Epithelial-Mesenchymal Transitions in Development and Disease

The origins of the mesenchymal cells participating in tissue repair and pathological processes, notably tissue fibrosis, tumor invasiveness, and metastasis, are poorly understood. However, emerging evidence suggests that epithelial-mesenchymal transitions (EMTs) represent one important source of these cells. As we discuss here, processes similar to the EMTs associated with embryo implantation, embryogenesis, and organ development are appropriated and subverted by chronically inflamed tissues and neoplasias. The identification of the signaling pathways that lead to activation of EMT programs during these disease processes is providing new insights into the plasticity of cellular phenotypes and possible therapeutic interventions.

TNFα induces expression of the chemoattractant cytokine RANTES in cultured mouse mesangial cells

Fibroblast proliferation and collagen synthesis play an important role in the progression of intersititial nephritis. To evaluate the involvement of immune mechanisms in this process, we induced intersititial nephritis in guinea pigs utilizing injections of tubular antigens. Over a 3-week period, injected animals developed a nephritis characterized by mononuclear infiltrates and expanding areas of fibrotic scar formation. Involved kidneys contained increased collagen as compared to controls. To identify mediators of the observed fibrogenesis, T lymphocytes from nephritic and control animals were stimulated with soluble tubular antigens. Dialyzed supernatants from control lymphocyte cultures contained an inhibitor of both fibroblast proliferation and collagen synthesis. In contrast, supernatants from nephritic animals demonstrated absence of inhibition and a progressively increasing titer of a factor that enhanced both kidney fibroblast proliferation and collagen synthesis. As the disease progressed, however, nephritic lymphocytes also began secreting an inhibitor of proliferation that could be detected in low levels. These studies suggest, therefore, that immune mechanisms and altered lymphocyte function may play an important role in the development, progression, and regulation of renal fibrogenesis in intersititial nephritis.
