[Factors related to oral candidiasis in HIV children and adolescents, species characterization and antifungal susceptibility].

Factors associated with candidiasis and colonization in HIV-positive children and adolescents in developing countries are not well understood.To identify the factors associated with oral Candida colonization and candidiasis in institutionalized HIV-positive children and adolescents in Tijuana, México, as well as the response of the isolates to antifungals.Sample of the oral mucosa of 30 HIV positive children and adolescents were obtained to isolate and identify Candida species by culture and metabolic profile. Antifungal drugs susceptibility was determined according to CLSI. Indicators of immunological and virologic failure were classified in accordance to WHO criteria.Six Candida species were identified from oral mucosa, 53% colonizers and 47% in candidiasis. Factors associated with candidiasis and oral colonization were viral load (p = 0,001), CD4+ counts (p = 0,002) and HAART regimen (p ≤ 0,014). The most prevalent species was C. glabrata (33%), but C. albicans (27%) was more resistant to fluconazole (p = 0,001). Itraconazol resistant species were identified in regimens that include an NNRTI (p = 0,041).HIV-positive children and adolescents living in an orphanage showed high prevalence of colonizing Candida spp. and resistance to antifungals, related to NNRTI.
