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.     

The prognostic value of circulating soluble cell adhesion molecules in patients with chronic congestive heart failure

BACKGROUND: Circulating soluble (s) cell adhesion molecules (CAMs) are elevated in patients with congestive heart failure (CHF) and may play an important role in the pathogenesis of CHF by mediating the cell-cell interactions of the immune response. However, clinical data about the prognostic value of sCAMs are sparse. The purpose of this study is to determine whether various sCAMs can provide prognostic information in patients with CHF. METHODS: We measured circulating levels of three sCAMs (vascular cell adhesion molecule-1, intercellular adhesion molecule-1, and sP-selectin) in 74 patients with symptomatic chronic CHF and left ventricular ejection fraction (LVEF) <50%. We compared these levels with those of a group of 19 age-matched control subjects. Major adverse cardiac events (death, heart transplantation or hospitalization with worsening CHF) during a median follow-up period of 240 days were determined. RESULTS: The concentrations of the three sCAMs in the 74 patients with CHF were significantly associated with one another. Their levels were higher than those of the control subjects and increased with the severity of CHF. Significantly higher sCAM levels were noted in those patients who had major adverse cardiac events during the follow-up period. There were significant negative correlations between LVEF and sCAMs. However, only high levels of sP-selectin were found to be an independent significant predictor of CHF by Cox proportional hazards analysis. CONCLUSIONS: These findings indicate that the levels of these three sCAMs increase with the severity of CHF and are related to clinical outcomes. Among them, high levels of sP-selectin can provide prognostic information independently in patients with CHF.

Exercise training in chronic heart failure: effects on pro-inflammatory markers

BACKGROUND: Acute bouts of exercise have been shown to induce inflammatory cytokine activation and peripheral hypoxia in patients with chronic heart failure (CHF). In this study, we set out to investigate the impact of chronic exercise training on pro-inflammatory cytokines and markers of endothelial damage. METHODS AND RESULTS: We measured tumor necrosis factor alpha (TNFalpha), its soluble TNF-receptors 1 and 2, interleukin 6 (IL-6), soluble e-selectin, soluble intracellular adhesion molecule-1 (sICAM) and sCD14 in 18 patients with CHF and 9 age-matched controls in a randomized cross-over study of 8 weeks of exercise training (5 days/week, submaximal bicycle ergometer training, 30 min/day; calisthenics 9 min/day) versus 8 weeks of rest. At baseline, patients had a lower peak Vo(2) (p=0.009) and a trend for higher levels of e-selectin (p=0.08) and sCD14 (p=0.06), in addition to significantly elevated levels of sICAM (p=0.02), TNFalpha (p=0.02) and TNF-R2 (p=0.002); TNF-R1 and IL-6 were not elevated. Although exercise training was effective and led to an increase in peak Vo(2) in CHF (p<0.003), there was no activation of any of the above variables observed, neither in patients nor controls. CONCLUSIONS: Chronic heart failure is associated with increased levels of TNFalpha and markers of endothelial damage. Whereas acute bouts of exercise have been reported to lead to an increase in pro-inflammatory cytokines and markers of endothelial damage, these effects are not seen when exercise is performed chronically.     

充血性心力衰竭患者血清VCAM-1、ICAM-1含量的变化

慢性心力衰竭患者贫血与肾功能和神经内分泌细胞因子的关系

目的探讨慢性心力衰竭(CHF)患者贫血与肾功能和神经内分泌细胞因子之间的关系。方法对入选的121例CHF患者测定血红蛋白(Hb)、肾功能、TNF-α、可溶性细胞间黏附分子-1(sICAM-1)、白细胞介素-6(IL-6)、血管紧张素Ⅱ(AngⅡ)、NO、内皮素(ET)的变化;超声心动图测量LVEF,评价心功能;按Hb水平分为贫血组(47例)和非贫血组(74例)。结果随着心功能恶化,CHF患者LVEF和Hb水平逐渐降低,而尿素、肌酐(Cr)、血尿酸(BUA)水平明显增高(P<0.01);贫血发生率为38.8%,肾功能障碍发生率为24.0%,随着LVEF下降,贫血和肾功能障碍逐渐增加且程度加重(P<0.05)。贫血组患者血清TNF-α、sICAM-1、IL-6、AngⅡ、NO、ET水平明显高于非贫血组(P<0.01)。Hb和LVEF与尿素、Cr、BUA呈负相关;Hb与TNF-α、sICAM-1、IL-6、AngⅡ、NO、ET呈负相关,而与LVEF呈正相关(P<0.01)。结论CHF患者机体存在细胞因子的过度表达和肾素-血管紧张素系统的过度激活及伴随肾功能的降低,可能导致了CHF患者贫血的发生,且贫血也参与并加重了CHF发生发展的病理生理过程。     

Haemostatic and inflammatory biomarkers in advanced chronic heart failure: role of oral anticoagulants and successful heart transplantation

Advanced chronic heart failure (CHF) is associated with abnormal haemostasis and inflammation, but it is not known how these abnormalities are related, whether they are modified by oral anticoagulants (OAT), or if they persist after successful heart transplantation. We studied 25 patients with CHF (New York Heart Association class IV, 10 of whom underwent heart transplantation) and 25 age- and sex-matched healthy controls by measuring their plasma levels of prothrombin fragment 1 + 2 (F1 + 2), thrombin-antithrombin (TAT) complexes, tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), D-dimer, factor VII (FVII), fibrinogen, von Willebrand factor (VWF), tumour necrosis factor (TNF), soluble TNF receptor II (sTNFRII), interleukin 6 (IL-6), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), endothelial-selectin (E-selectin) and thrombomodulin. CHF patients had higher plasma levels of TAT, D-dimer, t-PA, fibrinogen, VWF, TNF, IL-6, sTNFRII, sVCAM-1 (P = 0.0001), sICAM-1 (P = 0.003) and thrombomodulin (P = 0.007) than controls. There were significant correlations (r = 0.414-0.595) between coagulation, fibrinolysis, endothelial dysfunction and inflammation parameters, which were lower in those patients treated with OATs. Heart transplantation led to reductions in fibrinogen (P = 0.001), VWF (P = 0.05), D-dimer (P = 0.05) and IL-6 levels (P = 0.05), but all the parameters remained significantly higher (P = 0.01-0.0001) than in the controls. Advanced CHF is associated with coagulation activation, endothelial dysfunction and increased proinflammatory cytokine levels. Most of these abnormalities parallel each other, tend to normalize in patients treated with OATs and, although reduced, persist in patients undergoing successful heart transplantation, despite the absence of clinical signs of CHF.
