Therapeutic inhibition of tumour necrosis factor alpha in patients with heart failure: cooling an inflamed heart.
Heart failure is a systemic disorder characterised by tissue hypoxia and secondary organ dysfunction which occurs in response to various myocardial insults that include ischaemia, viral infections, and toxins. In addition to maladaptive neurohumoral activation, heart failure is associated with an inflammatory state that appears to have a detrimental effect on cardiac function and prognosis. Thi...
متن کاملIncreased concentrations of tumour necrosis factor in "cachectic" patients with severe chronic heart failure.
OBJECTIVE To ascertain whether patients with cardiac failure and reduced body weight ("cardiac cachexia") have increased circulating concentrations of tumour necrosis factor (cachectin). DESIGN Patients with cardiac failure were prospectively identified as "cachectic" (body fat less than 27% in men and less than 29% in women measured by skinfold thickness callipers) or "non-cachectic". Tumour...
متن کاملTumor necrosis factor-alpha as trigger of platelet activation in patients with heart failure.
The clinical history of patients with heart failure (HF) is complicated by arterial thromboembolism. Platelet activation is reported in this population, but the underlying mechanism has not been clarified. Forty-two patients with HF scored according to New York Heart Association (NYHA) classification had higher levels of collagen-induced platelet aggregation, platelet tumor necrosis factor-alph...
متن کاملTumour necrosis factor alpha as a predictor of impaired peak leg blood flow in patients with chronic heart failure.
Tumour necrosis factor alpha (TNF alpha) is increased in patients with cardiac cachexia, a condition associated with reduced peripheral blood flow both at rest and after interventions causing vasodilation. By contrast, in patients with chronic heart failure (CHF), higher TNF levels are associated with a greater capacity for vasodilation in the arm. To clarify the relationship between peripheral...
متن کاملCirculating tumour necrosis factor alpha and soluble tumour necrosis factor receptors in patients with different patterns of rheumatoid synovitis.
OBJECTIVE To examine the relation between the serum levels of tumour necrosis factor alpha (TNFalpha), soluble tumour necrosis factor receptors (sTNF-R), and the histological pattern of rheumatoid synovitis. METHODS An enzyme linked immunosorbent assay (ELISA) was used to measure TNFalpha, p55 sTNF-R, and p75 sTNF-R concentrations in the serum of 43 patients with rheumatoid arthritis (RA) and...
