Recurrent vulvovaginal candidiasis (RVVC) is a prevalent opportunistic
mucosal infection, caused predominantly by Candida albicans, which affects
a significant number of otherwise healthy women of childbearing age. Since
there are no known exogenous predisposing factors to explain the incidence
of symptomatic vaginitis in most women with idiopathic RVVC, it has been
postulated that these particular women suffer from an immunological
abnormality that prediposes them to RVVC. Because of the increased
incidence of mucosal candidiasis in individuals with depressed
cell-mediated immunity (CMI), defects in CMI are viewed as a possible
explanation for RVVC. In this review, we attempt to place into perspective
the accumulated information regarding the immunopathogenesis of RVVC, as
well as to provide new immunological perspectives and hypotheses regarding
potential immunological deficiencies that may predispose to RVVC and
potentially other mucosal infections by the same organism. The results of
both clinical studies and studies in an animal model of experimental
vaginitis suggest that systemic CMI may not be the predominant host defense
mechanism against C. albicans vaginal infections. Rather, locally acquired
mucosal immunity, distinct from that in the peripheral circulation, is now
under consideration as an important host defense at the vaginal mucosa, as
well as the notion that changes in local CMI mechanism(s) may predispose to
RVVC.
