Oral Carriage of Candida Species in HIV-infected Patients During Highly Active Antiretroviral Therapy (HAART) in Belém, Brazil

Objective: To identify the oral carriage of Candida spp in patients infected by human immunodeficiency virus (HIV) and the possible correlation with clinical characteristics.

Study Design: Mucosal swab samples collected from 246 patients who were infected by HIV, did not have oral candidiasis, and were being treated with highly active antiretroviral therapy were analyzed. Yeast colonies that developed were identified by using the VITEK 2 automated system.

Results: Candida yeasts were present in 41.87% of the samples, and Candida albicans was the most prevalent (32.52%). Other identified Candida species were C tropicalis (4.88%), C parapsilosis (2.85%), C dubliniensis (0.81%), and C famata (0.81%).

Conclusions: There was low rate of oral Candida carriage in patients infected by HIV who were on highly active antiretroviral therapy. A greater prevalence of C albicans than non-albicans Candida species was found at the species level. Prior candidiasis predicted the oral carriage of C albicans; however, it did not influence the carriage of non-albicans species. This is the first report of oral carriage of C famata in patients with HIV infection.
