摘要

Candida-associated denture stomatitis (DS) is the most frequent lesion among denture wearers, especially the elderly. DS is strongly associated with Candida albicans, as well as local and systemic factors, such as impaired immune response. Monocytes are important in the protective immune response against the fungus by the production of cytokines that recruit and activate leukocytes. There are functional changes in these cells with age, and individual alterations involving monocyte response may predispose the host to developing infections by Candida spp. In this study, our aim was to evaluate the production of TNF-alpha, IL-6, CXCL8, IL-1 beta, MCP-1 and IL-10 by monocytes from elderly denture wearers with/without DS and elderly or young non-denture wearers. We detected that monocytes from elderly denture wearers with Candida-related denture stomatitis produced lower levels of CXCL-8, IL-6 and MCP-I. This imbalance in cytokine levels was observed in spontaneous or LPS-stimulated production. Therefore, our data suggested that inherent aspects of the host, such as changes in cytokine production by monocytes, might be associated with the development and the persistence of DS irrespective of aging.
