Increased concentrations of soluble intercellular adhesion molecule-I (ICAM-1) have been reported in a number of diseases including cancer. This study was undertaken to evaluate soluble ICAM-1 in colorectal cancer and its relationship to an unspecific acute phase response. Fifty six patients (25 with advanced colorectal cancer and 31 out-patients after radical surgical treatment) were included. Soluble ICAM-1 was measured by enzyme immunoassay. Four acute phase proteins (C-reactive protein, acid alpha 1-glycoprotein, haptoglobin and ceruloplasmin) were estimated by immuno-nephelometry. No significant increase of soluble ICAM-1 could be demonstrated in the patients compared to a control group (median 273 ng/ml vs. 270 ng/ml). Furthermore, patients with advanced colorectal cancer did not demonstrate elevated soluble ICAM-1 compared to follow-up out-patients. Patients with present acute phase response as determined by C-reactive protein were shown to have increased soluble ICAM-1 compared to patients without acute phase reaction. Using other acute phase proteins no difference for soluble ICAM-1 has been shown. Our data suggest an association between acute phase response and increased ICAM-1 in patients with colorectal cancer which should be considered when the diagnostic and/or prognostic usefulness of soluble ICAM-1 is to be evaluated.

The aim of this study was to investigate whether or not the human immune system can be activated by a noninfectious stimulus, thereby improving the physiological status of the individual. The effect of a single cold water immersion (14 degrees C for 1 h) on the immune system of athletic young men, monitored immediately after immersion, was minimal. With the continuation of the cold water immersions (three times a week for a duration of 6 weeks) a small, but significant, increase in the proportions of monocytes, lymphocytes with expressed IL2 receptors (CD25) and in plasma tumour necrosis factor alpha content was induced. An increase in the plasma concentrations of some acute phase proteins, such as haptoglobin and haemopexin, was also observed. After 6 weeks of repeated immersions a trend towards an increase in the plasma concentrations of IL6 and the amount of total T lymphocytes (CD3), T helper cells (CD4), T suppressor cells (CD8), activated T and B lymphocytes (HLA-DR) and a decrease in the plasma concentration of alpha 1-antitrypsin was observed. Concentrations of IL1 beta, neopterin, C-reactive protein, orosomucoid, ceruloplasmin, macroglobulin, immunoglobulins (IgG, IgM, IgA) and C3, C4 components of the complement, as well as the total number of erythrocytes, leucocytes, granulocytes and neutrophils showed no significant changes after the repeated cold water immersions. It was concluded that the stress-inducing noninfectious stimuli, such as repeated cold water immersions, which increased metabolic rate due to shivering the elevated blood concentrations of catecholamines, activated the immune system to a slight extent. The biological significance of the changes observed remains to be elucidated.

Serum levels of alpha 1-antichymotrypsin (alpha 1-ACT), macroglobulin, alpha 1-antitrypsin, ceruloplasmin, acid glycoprotein, transferrin, and C-reactive protein were measured in patients with probable late onset dementia of Alzheimer type (I-AD), patients with vascular dementia (VD), healthy elderly (HC), and patients with chronic or acute inflammation. Three blood samples were taken at 10-15 day intervals. Serum alpha 1-ACT levels from first and second serum samples were elevated in one out of 11 I-AD patients. Serpin serum levels from the third sample were increased in four out of 11 I-AD patients. None of these patients showed increased levels of other acute phase proteins measured in the three serum samples. VD patients did not show abnormal serum levels of alpha 1-ACT. Serum levels of alpha 1-ACT along with those of other acute phase proteins were altered in patients with inflammation. This investigation showed that in I-AD patients with increased alpha 1-ACT and no concomitant elevation of other acute phase proteins, serum levels of alpha 1-ACT varied with time. Based on our results, serum alpha 1-ACT does not appear to be a useful biomarker for clinical diagnosis of probable I-AD, but it might be associated with the clinical history of the disease.

With the exception of fibrinogen, immunoglobulins, and albumin, little information is available on the effect of acute-phase proteins on erythrocyte aggregation. The objective of this study was to investigate the effects of haptoglobin (Hp), C-reactive protein (CRP), ceruloplasmin (Cp), alpha 1-acid glycoprotein (alpha 1-AGP), and alpha 1-antitrypsin (alpha 1-AT) on the aggregation kinetics and shear resistance of erythrocyte aggregates. The plasma concentration of these proteins was measured in 20 healthy individuals and kept unchanged while the concentration of the protein tested was increased. Adding Hp to concentrations between 2.78 and 4.99 g/l resulted in a significant progressive increase in aggregation kinetics compared with controls. An elevation of the shear resistance of the aggregates was found for CRP at a concentration of 0.438 g/l. By an increase in the concentration of Cp from 4.40 to 9.39 g/l, the aggregation kinetics and the adhesive forces between erythrocytes were significantly increased: No effect on erythrocyte aggregation was observed for alpha 1-AGP, alpha 1-AT, and Cp at concentrations of 2.85, 3.97, and 2.43 g/l, respectively. The molecular mass of the acute-phase proteins, their configuration, and the presence of specific receptors on the erythrocyte membrane are postulated as possible factors influencing erythrocyte aggregation.

In order to improve the non aggressive diagnosis of hepatic metastasis from digestive neoplasm, the authors analyzed the following biological parameters: aminotransferases, alkaline phosphatase and lacticodehydrogenase isoenzymes, gammaglutamyl-transpeptidase, conjugated and total bilirubin, C-reactive protein, type A, G, M immunoglobulins, C3 complement factor, alpha-1 acidic glycoprotein (orosomucoid), haptoglobin, ceruloplasmin, transferrin, albumin, prealbumin, ferritin. This work included 54 patients with digestive tract cancer (esophageal, gastric, colic, rectal, anal localizations), divided in two groups: M- (n = 27), without hepatic metastasis), and M+ (n = 27, with histological confirmed hepatic metastasis). The Mann-Whitney test showed significant differences for 12 parameters between the 2 groups. With more than 60% sensitivity (Se) and specificity (Sp), according to the ROC curves, the following parameters can be selected: Total alkaline phosphatase (Se 89%, Sp 70%) and their macromolecular H2 fraction, lacticodehydrogenase fraction 4 (Se 63%, Sp 63%), gammaglutamyl-transpeptidase (Se 85%, Sp 82%), ceruloplasmin (Se 64%, Sp 65%), aspartate-aminotransferase determination (Se 63%, Sp 65%).

This study examined the effect of an acute-phase response on plasma trace element concentrations of non-small cell lung cancer (NSCLC) patients. In normal subjects (n = 13) and NSCLC patients (n = 22), fasting concentrations of albumin, C-reactive protein, the trace elements iron, zinc, copper, and selenium, and their associated proteins transferrin, albumin, ceruloplasmin, and glutathione peroxidase were measured. The NSCLC patients were subdivided into two equal groups depending on whether they had a C-reactive protein concentration < 35 mg/l (Group 1) or > 35 mg/l (Group 2). Circulating zinc, iron, and transferrin concentrations were significantly lower in NSCLC Group 1 than in the control group (p < 0.05). Circulating concentrations of iron, zinc, and the binding proteins transferrin and albumin were significantly lower in NSCLC Group 2 than in the control group and NSCLC Group 1 (zinc not significantly different) (p < 0.01). In contrast circulating concentrations of copper and its binding protein ceruloplasmin were significantly increased in NSCLC Group 2 compared with NSCLC Group 1 and the control group (p < 0.01). Additionally, plasma selenium and glutathione peroxidase concentrations were significantly lower (p < 0.05) in NSCLC Group 2 than in NSCLC Group 1 and the control group. In the NSCLC patients there were significant negative correlations between concentrations of C-reactive protein and iron, transferrin, zinc, albumin, and selenium (p < 0.05). Furthermore, there were also significant positive correlations between C-reactive protein and copper (r = 0.788, p < 0.001) and ceruloplasmin (r = 0.831, p < 0.001) concentrations. The presence of an acute-phase response has implications for the interpretation of circulating trace element concentrations, the status of patients with NSCLC, and supplementation with trace elements in patients with NSCLC.

To identify a possible acute phase response during the steady state of sickle cell disease, we estimated the serum alterations of acute phase proteins, beta2-microglobulin (beta2M), kappa and lambda light chains, interleukins (ILs) and tumor necrosis factor-alpha (TNFalpha) in 21 patients. Increased concentrations of C-reactive protein (CRP) were found in 5 patients, alpha-1-acid-glycoprotein (AGP) in 3, alpha-1-antitrypsin (AAT) in 8, ceruloplasmin (CER) in 2, alpha-2-macroglobulin (AMG) in 14 and decreased haptoglobin (HPT) and transferrin (TFR) in 11 and 9, respectively. Increased beta2M was found in 10 patients and kappa and lambda light chains in 11. IL-1beta, IL-2, IL-4, IL-10 and TNFalpha were not detected in any of the patients. However, significantly increased values of IL-6 and sIL-2r were found. This study has demonstrated increased serum levels of some of the acute phase proteins in patients during the steady state of sickle cell disease. This may be a result of a subclinical vaso-occlusion which in turn leads to a covert inflammatory response. Cytokines, and in particular IL-6, produced after this response, seem to be responsible for the high levels of acute phase proteins in the steady state of this disease.

We have previously described the major components of rat serum (Electrophoresis 1998, 19, 1484-1492 and 1493-1500). In this report we examine sex-related differences in protein concentrations, both in control animals and upon experimentally induced inflammation. Under baseline conditions approximately one third of the spots resolved in serum by two-dimensional electrophoresis (2-DE) are expressed at levels > or =25% higher in female rats than in male rats and a further 10% at levels > or =25% lower. Inflammation increases the expression of the positive acute-phase reactants: hemopexin, ceruloplasmin, alpha1-antitrypsin (all approximately 2-fold), C-reactive protein (3- to 5-fold), serine protease inhibitor-3 (4- to 5-fold), thiostatin (> 5-fold in females, >20-fold in males), clusterin, orosomucoid, haptoglobin chains and alpha2-macroglobulin. The baseline level of the last four markers is below the detection limit, hence no percent increase can be computed. Conversely, negative acute-phase reactants are reduced on inflammation: alpha1-inhibitor III, alpha2-HS-glycoprotein, kallikrein-binding protein and transthyretin (all reduced to between 1/2 to 1/3 of the baseline levels), retinol-binding protein (to about 1/2 to 1/4) and albumin (to 2/3). Except for thiostatin, the changes in acute-phase protein levels are similar in male and female rats.

Changes in the concentration of major serum proteins were monitored from day 0 to day 4 in three experimental groups: rats injected with turpentine, rats receiving the turpentine shot and daily doses of indomethacine, and rats given indomethacine alone. In inflamed animals, peak changes for acute-phase reactants, evaluated by two-dimensional electrophoresis (2-DE), were usually observed between 48 and 72 h after the phlogistic stimulus. By itself, indomethacine was found to affect the synthesis of most proteins (except one of the thiostatin variants and ceruloplasmin); the changes in serum levels, whether positive or negative, were the same as upon inflammation (except for kallikrein-binding protein), but their extent and/or timing usually differed. When inflamed animals were given indomethacine, a clear-cut difference in the concentration of some proteins was observed versus inflamed rats not given medication, at 24 h after the start of the treatments. Proteins mainly affected were alpha2-macroglobulin, alpha2-HS-glycoprotein, C-reactive protein and kallikrein-binding protein.

The presence of an acute-phase protein response (APPR) has been suggested to shorten survival and contribute to weight loss in patients with pancreatic cancer. Fatty acids derived from fish oil have been shown to alter proinflammatory cytokine production and acute-phase protein synthesis in vitro. The present study was designed to determine the effects of a fish oil-enriched nutritional supplement on the concentrations of a range of individual acute-phase proteins (APP) in patients with advanced pancreatic cancer. In a sequential series, 18 patients with pancreatic cancer received the supplement (providing 2 g eicosapentaenoic acid and 1 g docosahexaenoic acid/d) for 3 wk while another 18 received full supportive care alone. Six healthy subjects served as additional controls. Acute-phase proteins were measured before and after the 3-wk intervention period in cancer patients. At baseline, albumin, transferrin and pre-albumin were significantly reduced and fibrinogen, haptoglobin, alpha-1-acid glycoprotein, alpha-1-antitrypsin, ceruloplasmin and C-reactive protein (CRP) were significantly elevated in the cancer patients compared with healthy controls, reflecting their roles as negative and positive acute phase proteins, respectively. In the supplemented cancer group, the only significant change in APP concentrations over the 4-wk study period was an increase in transferrin. In the control cancer group there were further significant reductions in albumin, transferrin and pre-albumin, and a significant increase in CRP concentration. These results suggest that many positive and negative APP are altered in advanced pancreatic cancer. The APPR tends to progress in untreated patients but may be stabilized by the administration of a fish oil-enriched nutritional supplement. This may have implications for reducing wasting in such patients.
