Background: The epidemiological and clinical aspects of oral opportunistic infections related to HIV infection (OOI-HIV) have been influenced by the different antiretroviral treatments. It is unknown if this behavior is gender-related. Therefore the principal objective was to establish the behavior of oral opportunistic infections related to HIV infection in the different antiretroviral therapies-eras in regard to gender.
Methods: A data base of 1126 HIV+/AIDS patients (775 males; 351 females) was used. The patients were oral examined from January 1993 to December 2007. All of the patients were undergoing antiretroviral therapy (minimum 6 months) at oral examination. In relation to antiretroviral therapy used the cohort were divided in 3 eras: pre-Highly Active Antiretroviral Therapy (pre-HAART) era (1993 to 1996); early-HAART era (1997 to 2003); and late-HAART era (2005 onwards). The prevalence of OOI-HIV in each era was established and the relative difference between pre-HAART era and late-HAART era was obtained. A lineal regression test was used with statistical purposes (s 0.05).
Results: From pre-HAART era to late-HAART era the Pseudomembranous candidiasis diminishes 86.9% (s 0.109) in males and 76.8% (s 0.06) in females. In the late-HAART era there were no cases of Hyperplastic candidiasis. On the other hand the prevalence of the Erythematous candidisis increased 14.7% in males and 7.9% in females. In regard to viral opportunistic infections, Herpes labialis diminishes 33.7% (s 0.015) in males and 32.7% (s 0.008) in females. There were no cases of Kaposi's Sarcoma in the late-HAART era. On the other hand Hairy leukoplakia increase 39.6% (s 0.01) in males and 139% in females (0.000).
Conclusions: The prevalence of oral opportunistic infections related to HIV-infection has been influenced by the different antiretroviral therapies-eras. The Erythematous Candidiasis and Hairy leukoplakia showed a behavior gender-dependent.
