Because a number of different cytokines have been reported to regulate the synthesis of human, murine, and rat acute phase proteins (APP), we studied the effect of cytokines on production of several major human APP in a single system, the human hepatoma cell line Hep 3B. Conditioned medium (CM) prepared from human blood monocytes activated with LPS in the presence of dexamethasone led to substantial induction of serum amyloid A (SAA) and C-reactive protein (CRP) synthesis whereas the defined cytokines IL-1 beta, TNF alpha, and medium from a human keratinocyte cell line (COLO-16), containing hepatocyte-stimulating factor activity, failed to induce these two major APP. Induction of SAA and CRP was accompanied by an increase in concentration of their specific mRNA. Size fractionation of CM from activated monocytes by fast protein liquid chromatography indicated that SAA- and CRP-inducing activity eluted as a single peak with a Mr of approximately 18 kDa. alpha 1-Antitrypsin, which also failed to respond to IL-1 beta or TNF alpha, was induced by both CM and medium from COLO-16 cells. The induction of AT by CM was accompanied by an increase in specific mRNA. Induction of ceruloplasmin and alpha 1-antichymotrypsin and decrease in the synthesis of albumin was achieved by both CM and IL-1 beta. Ceruloplasmin and albumin responded in a comparable fashion to both TNF alpha and medium from COLO-16 cells; the response of ACT to these cytokines was not evaluated. These results indicate that human SAA and CRP are induced in Hep 3B cells by products of activated monocytes but not by IL-1 beta, TNF-alpha, or some hepatocyte-stimulating factor preparations and that a group of heterogeneous mechanisms are involved in the induction of the various human APP.

Serum levels of alpha 1-antichymotrypsin (alpha 1-ACT) were measured in patients with early and late onset Alzheimer's disease (e-AD, 1-AD), patients with vascular dementia (VD) and healthy elderly. Patients with 1-AD were divided into two groups, one had normal alpha 1-ACT values and one had increased serum levels of alpha 1-ACT. Other acute phase proteins were also measured. The serum levels of alpha 2-macroglobulin (alpha 2-MG), alpha 1-antitrypsin (alpha 1-AT), ceruloplasmin (CER), transferrin (TRSF) and alpha 1-acid glycoprotein (alpha 1-ac.GL) were within the normal range. The C reactive protein (CRP) was occasionally detectable at low concentrations in e-AD, in both groups of 1-AD patients and in VD patients. Low serum concentrations of interleukin-6 (IL-6) were found in a higher proportion of 1-AD than in patients with e-AD or VD. These results indicated that increased levels of alpha 1-ACT along with occasional detection of IL-6 might be peripheral markers of the 'acute reaction' in the brain.

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.

The aim of this study was to quantitatively evaluate serum APP in patients undergoing the radical resection for NSCLC. The quantitative changes in APP were correlated with the cancer type, clinical staging and grading and the procedure type. Also, the impact of selected post-operative complications on the APP serum concentrations was evaluated. 46 patients undergoing surgery secondary to NSCLC in the years 2003-2004 were analyzed. The patients' age varied from 45 to 77 years with an average of 61.1. The most common pathological cancer type was the squamous cell cancer (24 patients) and adenocarcinoma (17 patients). The majority of the patients were stage IIB (15 patients) and IIIA (14 patients). The following APPs were evaluated in the patients' serum by Laurell rocket immunoelectrophoresis: C-reactive Protein (CRP), alfa-1 antichymotrypsine (alfa-1 ACT), alfa-1 antitrypsine (AT), alfa-2 macroglobuline (alfa2 M), ceruloplasmin (Cp), haptoglobine (Hp) and transferrin (Tf). Significantly higher serum AT level were found in patients with adenocarcinoma as compared to other pathology types. Patients with the squamous cell cancer had a significantly higher level of alfa-2 M and Cp. There was no significant difference in APP levels between the cancer grading types. In the group of patients with T3 or T4 stage the following five APPs were significantly elevated: CRP, AGP, alfa-1 ACT, alfa-2 M and Cp. Patients with regional lymph nodes metastasis (N2 or N2) had significantly higher level of AT, CRP and Hp. Patients undergoing more significant procedures (pneumonectomy, prolonged procedure time) and those with morbidities (rethoracotomy, blood transfusions) showed significantly higher levels of alfa-1 ACT, AGP and Cp. The most common post-operative complications were prolonged air-leak requiring probronchoscopy. In both complications a significantly higher level of AGP was observed. Patients with adenocarcinoma of the lung and regional lymph node metastasis have significantly higher serum levels of AT. This protein could be considered as one of the indicators of cancer involvement and could be a marker of the cancer recurrence. AGP is a protein that correlates positively with a more advanced clinical stage, and the extent of the surgical procedure as well as with the higher risk of morbidity. This could serve as a marker of higher post-operative complication rate.
