Abstract
Background: Chronic periodontitis (CP), caused by bacteria and fungi, appears in up to 66% of HIV-patients. The impact and association of HIV-treatment (HAART) and Candida itself has not been properly evaluated in the development and progression of CP. The immunopathogenesis is characterized by CD4+ T-cells activation and the balance between the T-helper 1 (Th1) and T-helper 2 (Th2) or a mixed cytokine profile. Currently, the associated causes of an immune response in HIV-patients with CP is controversial. Our aims were the determination of Candida spp. and cytokine profile in oral samples from HIV-positive patients with CP, considering the CD4+ T cells levels and HAART use. Methods: From 500 HIV-positive patients evaluated, 228 patients were enrolled. Patients were separated in groups: (A) n = 53 (≤200 CD4+ T-cells on HAART); (B) n = 57 (≤200 CD4+ T-cells without HAART); (C) n = 50 (>200 CD4+ T-cells without HAART); (D) n = 68 (>200 CD4+ T-cells on HAART). Candida spp. were isolated from the oral biofilm and crevicular fluid in CHROMagar and confirmed by endpoint PCR. Cytokine levels were measured by beads-based immunoassay in saliva by flow cytometry. Results: 147 patients (64.5%) were positive to Candida spp. and 204 strains were isolated; 138 (67.6%) were C. albicans and the remaining C. non-albicans species (C. glabrata>C. tropicalis>C. krusei>C. dubliniensis). In this study, CHROMagar showed good sensitivity (95%) but poor specificity (68%); since of the 152 samples identified as C. albicans, only 131 were confirmed by PCR; from the 10 samples identified as C. glabrata, only six were confirmed. Finally, of the 42 samples detected as C. tropicalis, only five were confirmed. When evaluating Candida spp. presence, group A and D had higher isolation, while group B had the highest species diversity. Whereas, group C had a significant reduction of Candida spp. Despite the presence of Candida and HAART, we found a Th1/Th2 hybrid profile in the saliva of patients with low CD4+ T-cell count (group A). Conclusion: Abundance and diversity of the Candida spp. detected in HIV-patients with CP could be related to HAART and low CD4+ T-cells levels. Also, the immunosuppression might promote a local Th1/Th2 hybrid cytokine profile.

Abstract
Candidiasis is the most common opportunistic fungal infection in HIV patients. The aims of this study were to identify the prevalence of carriers of Candida, Candida species diversity, and in vitro susceptibility to antifungal drugs. In 297 HIV/AIDS patients in Baja California, Mexico, Candida strains were identified by molecular methods (PCR-RFLP) from isolates of oral rinses of patients in Tijuana, Mexicali, and Ensenada. 56.3% of patients were colonized or infected with Candida. In Tijuana, there was a significantly higher percentage of carriers (75.5%). Out of the 181 strains that were isolated, 71.8% were Candida albicans and 28.2% were non-albicans species. The most common non-albicans species was Candida tropicalis (12.2%), followed by Candida glabrata (8.3%), Candida parapsilosis (2.2%), Candida krusei (1.7%), and Candida guilliermondii (1.1%). Candida dubliniensis was not isolated. Two associated species were found in 11 patients. In Mexicali and Ensenada, there was a lower proportion of Candida carriers compared to other regions in Mexico and worldwide, however, in Tijuana, a border town with many peculiarities, a higher carrier rate was found. In this population, only a high viral load was associated with oral Candida carriers. Other factors such as gender, use of antiretroviral therapy, CD4+ T-lymphocyte levels, time since diagnosis, and alcohol/ tobacco consumption, were not associated with Candida carriers.

Abstract
BACKGROUND Clinical markers that may predict virological failure during highly active antiretroviral therapy (HAART) have not been evaluated adequately. The aim of the present study was to evaluate the usefulness of human immunodeficiency virus (HIV)-related oral lesions as clinical predictors of virological failure in HIV-infected patients receiving HAART. METHODS A nested case-control study was conducted within a cohort of 1134 HIV-infected patients receiving HAART who attended the AIDS Clinic of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán in Mexico City during the period 1997-2005. Case patients were patients who, after achieving an undetectable viral load, had at least 1 viral load determination > or = 2000 copies/mL while receiving treatment. Control subjects were patients who, after achieving an undetectable viral load, continued to have undetectable viral loads during the follow-up period. There were 2-3 control subjects for each case patient, matched according to duration of follow-up. Oral examinations were blinded to viral loads and CD4+ lymphocyte counts. Analyses were performed with multivariate conditional logistic regression models, and associations were shown as odds ratios (ORs) with 95% confidence intervals (CI). Positive predictive values were calculated. RESULTS The target cohort consisted of 431 HIV-infected individuals; 47 case patients and 132 control subjects underwent complete oral examinations and formed the basis of the analysis. At the visit at which an undetectable viral load was determined, case patients and control subjects showed a similar frequency of HIV-related oral lesions (21.3% vs. 17.4%) (OR, 1.39; 95% CI, 0.57-3.38; P=.47). At the visit at which virological failure was determined, case patients showed a higher risk for HIV-related oral lesions (OR, 14.5; 95% CI, 4.21-49.94; P<.001) and oral candidosis (OR, 26.2; 95% CI, 3.34-205.9; P<.001) than did control subjects. The positive predictive value of HIV-related oral lesions and oral candidosis to identify patients who experienced virological failure while receiving HAART was 80% and 83%, respectively. CONCLUSIONS HIV-related oral lesions and, specifically, oral candidosis may be considered to be clinical markers of virological failure in HIV-infected patients receiving HAART.

Abstract
An observational, prospective, longitudinal cohort study was performed at the AIDS Clinic of a tertiary care institution in Mexico City to determine the association of viral load (VL) and CD4+ lymphocyte kinetics with the development of oral candidosis (OC) and hairy leukoplakia (HL). Participants were HIV-infected adult subjects, without a history of or current OC or HL, not receiving HAART. Oral examinations were performed at baseline and every month for evidence of OC or HL; CD4+ and VL determinations were done at baseline, at 6-month intervals, when oral lesions were detected, and 2 months later. Affected subjects (OL group) by OC or HL had clinical intervals defined before (antecedent), during (concurrent), and after their development. In the nonaffected individuals (NA group), 6-month intervals were determined. Differences (changes) along the clinical and study intervals were calculated for CD4+ and VL. The median study time was 178 (range: 31-924) days; 99 patients were included. The 2-year cumulative incidence of either oral lesion was 54% (49.5% for OC and 33.2% for HL). In the OL group (31 patients) a progressive and continuous decrease of CD4+ was found in the antecedent interval followed by a significant increase in VL in the concurrent period. The NA group showed a significant fall in CD4+ by semester 3, without a significant rise of VL in the following semester. The effect of CD4+ remained significant in a multivariate analysis. This study has shown that the onset of OC and/or HL is heralded by the sequence of a sustained reduction of CD4+, followed by a sharp increase of VL. In the multivariate analysis, the decrease in CD4+ lymphocytes appeared to be the predominant factor predicting the appearance of these oral lesions. Their potential use as markers of a recent change in the immunologic and virologic status of HIV-infected individuals is emphasized.

Abstract
HIV infection affects residents of all countries of the world, but the greater majority of affected individuals reside in the developing world. In the past decade there have been substantial changes in the management of HIV disease, particularly the introduction of highly active antiretroviral therapy (HAART). Such agents have reduced significantly the morbidity and mortality associated with HIV disease, however, they are not available for most HIV-infected individuals in the developing world. There is now considerable understanding of the molecular epidemiology, transmission and therapy of the common opportunistic oral infections of HIV disease, and as a consequence of improved anti-HIV strategies, the frequency and severity of oral disease associated with HIV infection have reduced considerably, although HAART may predispose to human papilloma virus infection of the mouth and potentially increase the risk of later oral squamous cell carcinoma. Despite advances in clinical care the majority of individuals with HIV disease worldwide will continue to develop oral disease, as they are resident in the developing world and do not have ready access to even simple therapies.

Abstract
OBJECTIVES We sought to assess asymptomatic oral carriage of Candida species and relative density in human immunodeficiency virus-infected (HIV+) subjects, as well as to determine whether yeast carriage is associated with CD4+ cell count, HIV-1 RNA quantity, gender, route of HIV transmission, antiretroviral therapy, or smoking. STUDY DESIGN A cross-sectional analysis of oral rinses from HIV+ and healthy subjects was undertaken. Oral candidal carriage and relative species were investigated in 42 HIV+ and 41 healthy individuals, all of whom were seen at the Palermo University Department of Oral Sciences, Italy. Data were managed and analyzed by means of the computer software package StatView 5.0.1. RESULTS Carriage rate was 61.9% and 29.3% (P =.003) among HIV+ and healthy subjects, respectively. Similarly, density carriage in the HIV+ group was found to be significantly higher than in the control group (P = .0002). Among HIV+ subjects, Candida carriage was significantly associated with smoking, whereas density was not. Oral candidal carriage and relative density were not significantly associated with the other 4 parameters evaluated. Candida albicans was the most frequently recovered species. CONCLUSIONS Asymptomatic candidal carriage and relative density were found to be significantly higher in the oral cavity of HIV+ subjects-but not associated with CD4+ counts or HIV-1 RNA quantities.

Abstract
OBJECTIVE The purpose of this study was to investigate the relationship between oral lesions and gender, age, CD4(+) cell count, human immunodeficiency virus-1 (HIV-1) viral load, antiretroviral therapy, and route of transmission in a group of HIV-infected (HIV+) persons from the Mediterranean region. STUDY DESIGN The participants in this study were HIV+ adults who sought dental care between January 1999 and June 1999 in the Department of Oral Medicine (University of Palermo, Italy). RESULTS One hundred thirty-six HIV+ adults came in for an initial oral examination. Their mean age was 35.2 years (SD +/- 7.97), and 33% were women. Their mean CD4(+) cell count was 325.3 x 10(6) /L (SD +/- 225.8), and their HIV-1 viral load was 39,168.3 copies/mL (SD +/- 144,256.1). Oral lesions were found in 47% of the study group, as well as in 56.5% of women (n = 46) versus 45.5% of men (n = 90; P =.05). Oral candidiasis was the most common disease; it is significantly associated with women (P =.004), CD4(+) cell count (P =.005), and HIV-1 viral load (P =.0003). No significant relationships were found between any types of oral lesions and age, antiretroviral therapy, or route of transmission (P >.2). CONCLUSION The prevalence of HIV-related oral lesions was significantly higher in women than in men, especially for oral candidiasis, the most common lesion observed related to immune status and HIV-1 viral load.
