Oral Candida albicans in HIV Infection

Abstract

The prevalence of oral colonization with Candida albicans was studied in 225 homosexual men, 99 of whom had HIV antibodies and in 175 heterosexual men. Oral candidal carriage was most prevalent among HIV seropositive homosexual men (77.8 %). Rich growth of C. albicans in culture and findings of pseudomycelial elements in oral mucosal smear also correlated with HIV seropositivity. Pseudomycelial forms of C. albicans were demonstrated in mucosal smear from all patients with oral mucosal lesions suspected for candidiasis. However, 26/53 patients (49.1 %) with positive smear had no clinical signs of oral candidiasis. The oral yeast flora was sampled twice in 85 homosexual men at an interval of 12–18 months. 71/85 patients (83.5 %) were grouped into the same category of candidal colonization; carrier or noncarrier state, on both occasions. No statistically significant differences in numbers of CD 4 cells or CD 8 cells were observed between patients with respect to candidal colonization, when HIV seropositive and seronegative homosexual men were considered separately.
