Although a zonal distribution of hepatocytes expressing various metabolic functions in liver lobule has been described (1), it is still debated whether functional heterogeneity in the lobule also occurs with respect to plasma protein synthesis, an important function ofhepatocytes . Acute-phase reactants are a group of secretory proteins with dramatically altered rates of synthesis during the ac...

The hyper-IgD and periodic fever syndrome (HIDS) and familial Mediterranean fever (FMF) are both characterized by attacks of periodic fever accompanied by acute phase responses that are substantially higher in HIDS than in FMF. To determine whether this difference could be due to differences in production of acute phase protein-inducing mediators, we studied PBMC from HIDS and FMF patients in t...

The serum amyloid A (SAA) family of proteins is encoded by multiple genes that display allelic variation and a high degree of homology in mammals. Triggered by inflammation after stimulation of hepatocytes by lymphokine-mediated processes, the concentrations of SAA may increase during the acute-phase reaction to levels 1000-fold greater than those found in the noninflammatory state. In addition...

Abstract: Adenoviruses (ADV) often cause respiratory infections. They have, in contrast to other respiratory viruses via a potential acute phase parameter (C-reactive protein, leukocytes and interleukin 6) to trigger. ADV infections are associated with increased secretion of IL-6 and TNF-?lpha, which activates the synthesis of acute phase proteins. The exact pathogenic mechanism is still unclea...

The acute phase response is an important adaptive response to sepsis and injury. As anabolic steroids increase protein synthesis we postulated that these agents might also increase hepatic acute phase protein synthesis. Male Wistar rats were pretreated with testosterone or danazol for 48 h prior to caecal ligation and puncture (CLP). Thirty-six h following surgery the animals were killed and bl...

OBJECTIVE To determine whether acute-phase protein measurement provides clinically useful information about tumor recurrence. PATIENTS AND METHODS Acute-phase serum protein levels were measured at regular intervals in 43 patients who underwent curative gastrectomy for gastric cancer. At 12 months after surgery, patients were grouped according to the presence or absence of a C-reactive protein...

The level of the acute-phase response is a major predictor of survival in patients with advanced pancreatic cancer. This study examines the association between the acute-phase protein response, as determined by serum C-reactive protein, and serum levels of interleukin-6, soluble interleukin-6 receptor and the soluble tumour necrosis factor receptors in patients with pancreatic cancer. Thirty-fo...

The ob gene product leptin is known to produce anorexia and loss of body fat when chronically administered to both lean and genetically obese mice. The current study was undertaken to examine whether administration of recombinant leptin in quantities sufficient to produce decreases in food intake and body weight and alterations in body composition would elicit either an hepatic acute phase prot...
