Angiotensin II type 1 receptor antagonist decreases plasma levels of tumor necrosis factor alpha, interleukin-6 and soluble adhesion molecules in patients with chronic heart failure

OBJECTIVES: To evaluate the effects of an angiotensin (Ang II) type 1 receptor antagonist on immune markers in patients with congestive heart failure (CHF). BACKGROUND: Ang II stimulates production of immune factors via the Ang II type 1 receptor in vitro, and the long-term effects of Ang II type 1 receptor antagonists on plasma markers of immune activation are unknown in patients with CHF. METHODS: Twenty-three patients with mild to moderate CHF with left ventricular dysfunction were randomly divided into two groups: treatment with Ang II type 1 receptor (candesartan cilexetil) (n = 14) or placebo (n = 9). We measured plasma levels of immune factors such as tumor necrosis factor alpha (TNFalpha), interleukin-6 (IL-6), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1). We also measured plasma levels of the neurohumoral factors such as atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) and cyclic guanosine monophosphate (cGMP), a biological marker of ANP and BNP. RESULTS: Plasma levels of TNFalpha, IL-6, sICAM-1 and sVCAM-1 were increased in the 23 CHF patients compared with normal subjects and significantly decreased after 14 weeks of candesartan cilexetil treatment, but did not change in the placebo group. Plasma levels of BNP, which is a marker of ventricular injury, significantly decreased, and the molar ratio of plasma cGMP to cardiac natriuretic peptides (ANP + BNP) was significantly increased after candesartan cilexetil treatment, but did not change in the placebo group. CONCLUSIONS: These findings suggest that 14 weeks of treatment with an Ang II type 1 receptor antagonist (candesartan cilexetil) decreased plasma levels of the immune markers such as TNFalpha, IL-6, sICAM-1 and sVCAM-1 and that it improved the biological compensatory action of endogenous cardiac natriuretic peptides in patients with mild to moderate CHF.

Serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) are elevated in advanced stages of non-Hodgkin's lymphomas

The serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in 116 patients with non-Hodgkin's lymphomas (NHL) tested previously for soluble intercellular adhesion molecule-1 (sICAM-1). In contrast to Hodgkin's disease and chronic lymphocytic leukaemia, the sVCAM-1 levels in NHL patients were not significantly different from the levels of healthy controls (n = 31). However, sVCAM-1 was elevated in advanced stage disease, i.e. stages III + IV. Elevated serum levels of sVCAM-1 were associated with significantly poorer disease-free (p = 0.024) and overall (p = 0.02) survival. sVCAM-1 correlated poorly with other known prognostic variables (LDH, sTK and beta 2m) and with sICAM-1. None of the tested markers added prognostic information for disease-free survival independently of Ann Arbor stage and B-symptoms. The expression of VCAM-1 and ICAM-1 in tumour biopsies from 15 patients representing 7 different histologies were examined and compared with the serum levels of the soluble adhesion molecules. No correlation was found between the adhesion molecule expression by vascular endothelium and the corresponding serum levels.     

Serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) are elevated in advanced stages of non-Hodgkin's lymphomas

Abstract: The serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in 116 patients with non-Hodgkin's lymphomas (NHL) tested previously for soluble intercellular adhesion molecule-1 (sICAM-1). In contrast to Hodgkin's disease and chronic lymphocytic leukaemia, the sVCAM-1 levels in NHL patients were not significantly different from the levels of healthy controls (n = 31). However, sVCAM-1 was elevated in advanced stage disease, i.e. stages III + IV. Elevated serum levels of sVCAM-1 were associated with significantly poorer disease-free (p = 0.024) and overall (p = 0.02) survival. sVCAM-1 correlated poorly with other known prognostic variables (LDH, sTK and β₂m) and with sICAM-1. None of the tested markers added prognostic information for disease-free survival independently of Ann Arbor stage and B-symptoms. The expression of VCAM-1 and ICAM-1 in tumour biopsies from 15 patients representing 7 different histologies were examined and compared with the serum levels of the soluble adhesion molecules. No correlation was found between the adhesion molecule expression by vascular endothelium and the corresponding serum levels.
