Correlation of atherogenesis with an infection of Candida albicans.

purposeTo study contents of atherosclerotic plaques for the presence of fungi of the genus Candida; and an analysis of some immunological and biochemical indices in patients with acute coronary syndrome (ACS) that are positive for Candida albicans. MATERIALS AND

methodsTo test for the presence of fungi in an atherosclerotic plaque, we used a method developed by us (patent NO 531, a priority from 6/28/2010). A total of 47 atherosclerotic plaques were obtained during 20 autopsies. In addition, 80 individuals (58 male, 22 female; age range from 29 to 85) with acute coronary syndrome were subjected to a blood biochemical test, including quantification of TNF-α levels and IgG and IgM to Candida albicans was determined.

resultsFungi of the genus Candida were identified in 31.9% (15 out of 47) of atherosclerotic plaques. Particularly, Candida krusii and Candida grabrata were identified in overwhelming majority, although solitary colonies of Candida tropicalis and a single colony of Candida albicans were also detected. 80 (100%) patients were negative for IgM, but 30 (37.5%) were positive for IgG to Candida albicans. TNF-α was detected in a smaller quantity of IgG-negative patients (36.7%) relative to patients of IgG-positive group (70%), however its levels were considerably above in the first group (511.73±195.80 pg/ml) than in the second one (326.68±259.91 pg/ml, P < 0.05). Differences in the levels of ASAT and ALAT in patients positive to Candida albicans and negative for TNF-α were significantly higher than in the rest of patients.

conclusionIt is conceivable that fungi of the genus Candida are capable of inducing an inflammation of the vascular wall that in turn can lead to the development of atherosclerosis.
