Highly active antiretroviral therapies (HAARTs) that contain human immunodeficiency virus (HIV) protease inhibitors (PIs) or nonnucleoside reverse-transcriptase inhibitors (NNRTIs) were compared for their effect on secretory aspartyl proteinase (Sap), a virulence trait for mucosal candidiasis. In therapy-naive HIV-positive subjects, oral Sap was detected in 11, 6, 3, 0, and 0 of 15 subjects treated with PI-HAART and in 7, 7, 9, 6, and 5 of 15 subjects treated with NNRTI-HAART, on days 0, 14, 30, 90, and 180 of treatment, respectively. In another 30 subjects, Sap was detected in 0 and 7 of 15 subjects after 1 year of treatment with PI-HAART or NNRTI-HAART, respectively. The anti-Sap effect of PI-HAART was associated with clinical resolution of oral candidiasis but not with late and inconstant recovery of anticandidal cellular immunity. In all subjects, the 2 therapeutic regimens compared well in increasing CD4(+) cell count and abating viremia. Thus, PIs exert an early, immune reconstitution-independent effect on Candida virulence in the oral cavities of HIV-positive subjects.

Total mRNA of Candida strains( isolated form whole vaginal swabs) was investigated and the in vivo expression of C. albicans secreted aspartyl proteinase (SAP4), aglutinin-like sequence (ALS1) and hyphal wall protein (HWP1) genes was determined. A spectrum of gene expression profiles of strain isolated from vulvovaginal candidiasis(VVC) cases consisting of 10 pregnant, 4 postmenopausal, and 15 reproductive age (12 primary and 3 recurrent) 9 women with different estrogen level. Expression of SAP4, ALS1 and HWP1 genes was evaluated by reverse-transcriptase polymerase chain reaction using specific primer sets. The expression of ALS1, HWP1, and SAP4 was detected as 69, 62, and 38 %, respectively, in all cases. In pregnant, postmenopausal, and reproductive age women with VVC, the expression of ALS1 was observed as 70, 75, 67%, and HWP 60, 25, 73% respectively . Expression of SAP4 was found in pregnant, postmenopausal, and reproductive age women as 40, 50, and 33% respectively. Expression of teh adhesion genes in VVC does not correlate with estrogen level of patients.
