Abstract:
:Acute coronary syndromes (ACS) are associated with inflammation resulting from monocyte activation. We sought for differences in the production of pro- and anti-inflammatory cytokines by monocytes from patients with ACS. C-reactive protein (CRP) and neopterin were measured in 22 patients with acute coronary syndromes, 50 patients with stable vascular disease and 22 healthy controls. Production of tumour necrosis factor (TNF)-alpha and interleukin (IL)-10 was determined after, respectively, 6 and 24 h of incubation of full blood with lipopolysaccharide (LPS). Levels of CRP [median, interquartile range (IQR)][1.5 mg/l (0.8-4.5) ACS patient versus 2.1 (0.9-3.6) stable disease versus 0.4 (0.3-1.2) healthy controls] (P < 0.001) and neopterin [7.4 nmol/l (6.0-8.7) ACS patient versus 7.1(6.0-8.9) stable disease versus 6.4 (5.6-7.3) healthy controls] (P = 0.07) were higher in both the patient groups. IL-10 production after LPS stimulation was greatly reduced in patients with acute coronary syndromes (16 175 pg/ml, 7559-28 470 pg/ml) as opposed to patients with stable disease (28 379 pg/ml, 12 601-73 968 pg/ml) and healthy controls (63 830 pg/ml, 22 040-168 000 pg/ml) (P = 0.003). TNF-alpha production was not signi fi cantly different between the groups [7313 pg/ml (4740-12 615) ACS patient versus 11 002 (5913-14 190) stable disease versus 8229 (5225-11 364) healthy controls] (P = 0.24). Circulating monocytes in unstable coronary syndromes produce equal amounts of TNF-alpha but less IL-10 after stimulation with LPS in vitro as compared with healthy controls. We hypothesize that, in acute coronary syndromes, the production proinflammatory cytokines is not counterbalanced by anti-inflammatory cytokines such as IL-10.
