The optimum anti-HIV drug has yet to be found. This paper will summarise some of the oral adverse effects associated with antiretroviral agents against HIV. The development of antiretroviral drugs for the treatment of HIV infection has been aimed at the inactivation of two HIV enzymes: reverse transcriptase and proteases. Erythema multiforme, ulcers and xerostomia are the main oral side effects associated with reverse transcriptase inhibitors. Parotid lipomatosis, taste disturbance, xerostomia and perioral paraesthesia are oral adverse effects, which are mainly related to protease inhibitor therapy. The search for new antiretrovirals with different active mechanisms and patterns of resistance constitutes a key question in HIV treatment. The use of new drugs and drug combinations will lead to the appearance of oral lesions, which will be difficult to identify and treat and which cannot be ignored by the practitioner.

Oral lesions (OL) have an important prognostic value for HIV/AIDS patients. However, the behavior of OL in HIV/AIDS patients undergoing highly active antiretroviral therapy including efavirenz (HAART/EFV) has not been documented. Our objective was to establish the prevalence of OL in HIV/AIDS patients undergoing HAART/EFV and to compare it with the prevalence of OL in patients undergoing antiretroviral therapy including a protease inhibitor (HAART/PI). Seventy-three HIV/AIDS patients undergoing antiretroviral treatment for at least for 6 months at "La Raza" Medical Center's Internal Medicine Unit (IMSS, Mexico City) were included. To detect OL, a detailed examination of oral soft tissues was performed in each patient. Patient records recorded gender, seropositivity time, route of contagion, antiretroviral therapy type and duration, CD4 lymphocyte count/ml, and viral load. Two groups were formed: 38 patients receiving HAART/EFV [two nucleoside analogue reverse transcriptase inhibitors (NARTI) plus efavirenz] and 35 patients receiving HAART/PI (two NARTIs plus one PI). OL prevalence was established in each study group. The Chi-square test was applied (p < 0.05(IC95%)). OL prevalence in the HAART/EFV group (32%) was lower (p < 0.007) than in the HAART/PI group (63%). Candidosis was the most prevalent OL in both groups. Herpes labialis, HIV-associated necrotizing periodontitis, xerostomia, hairy leukoplakia, and nonspecific oral sores were identified. The highest prevalence for all OL was found in the HAART/PI group. These findings suggest that HIV/AIDS patients undergoing HAART/EFV show a lower prevalence of oral lesions than patients undergoing HAART/PI.
