Abstract

Background: Increased levels of bacterial lipopolysaccharide (LPS) have been demonstrated in chronic heart failure (CHF). LPS can induce cellular desensitization, with specific down-regulation of LPS-mediated cellular tumor necrosis factor (TNF-α) production which does not affect other cytokine parameters. It is not known if LPS desensitization occurs in CHF. Methods and results: Mononuclear cells from 24 CHF patients (mean age 70±2 years, age range 58 to 78 years, NYHA class 3.0±0.2) and 11 healthy controls (mean age 53±3 years, age range 39 to 75 years) were separated from venous blood and cultured for 24 h with LPS (E. coli, 0-10 ng/mL). Culture supernatants were tested for TNF-α and interleukin-1 receptor antagonist (IL-1RA). Patients were subgrouped into mild (n=10), moderate (n=5), and severe (n=9) CHF. Independently of age, mononuclear cells from patients with severe heart failure produced less TNF-α than controls (p
