Objective: Human fetuin/2HS-glycoprotein (AHSG) is synthesized by hepatocytes. We intended to determine whether liver dysfunction or acute phase reaction is dominant in the regulation of its serum concentrations and to see if decreased AHGS levels are associated with short-term mortality. Design:We determined the serum AHSG levels in patients with acute alcoholic, acute A, B, and Epstein-Barr virus hepatitis, alcoholic cirrhosis, and hepatocellular cancer and correlated them to conventional laboratory parameters of inflammation and liver function. Patients were followed for one month.Methods: Serum AHSG was determined by radial immunodiffusion. Results:Compared to controls, significantly lower levels were found in patients with liver cirrhosis and hepatocellular cancer but not the acute viral hepatitides. Strong positive correlation with serum transferrin, albumin, prothrombin was found.Febrile episodes were not associated with significantly decreased AHSG levels.Concentrations below 300 g/ml were associated with high mortality rate (52.0%, relative risk: 5.497, 95% C.I.: 2.472-12.23, p<0.0001). Of all laboratory parameters studied serum AHSG levels showed the greatest difference between deceased and survived patients with cirrhosis and cancer. Moreover, other acute phase reactants did not differ significantly. The multiple logistic regression analysis indicated that the decrease of serum AHSG patients is independent from all other variables that were found decreased in deceased patients. Conclusions: Decreased serum AHSG concentration is due rather to hepatocellular dysfunction than the acute phase reaction and is an outstanding predictor of short-term mortality in patients with liver cirrhosis and liver cancer.

Objectives: The aim of the present study was to investigate the role of soluble adhesion molecules in the pathogenesis of multiple sclerosis (MS) and systemic lupus erythematosus (SLE) with demyelinating syndrome. Methods: Paired cerebrospinal fluid (CSF) and serum samples were analysed by an ELISA method to determine the concentrations of sVCAM-1, sICAM-1 and sL-selectin. Intrathecal syntheses of the adhesion molecules were calculated. Results: Elevated serum and CSF concentrations of sVCAM-1 were present in all patient groups. Intrathecal synthesis of sVCAM-1 was present in the relapsing-remitting and secondary progressive forms of MS. Intrathecal synthesis of sICAM-1 was observed in all clinical forms of MS. MS patients with progressive forms of the disease and SLE patients were characterised by intrathecal synthesis of sL-selectin. Conclusions: The data presented suggest that (1) blood-brain barrier damage can be assumed both in systemic disease and organ-specific disease (sVCAM-1), (2) clinical forms of MS differ from each other in respect to concentrations of adhesion molecules and (3) similar immunological events in the central nervous system of SLE patients with demyelinating syndrome and progressive forms of MS can be assumed (sL-selectin).

Authors report a case of Castleman's disease (CD) with polyneuropathy, organomegaly, endocrinopathy, M protein, skin change (POEMS) syndrome. According to the present knowledge, these two rare conditions are often induced by Human Herpes Vírus- 8 (HHV-8) or by Human Immunodefeciency Virus, separately or in combination. In this case, however, HHV-6 viral DNA had been detected in the blood and lymph node samples by PCR. The authors conclude that the modulation of immune functions by HHV-6 might be responsible for the development of CD and POEMS syndrome in the referred case.
