Purpose: Tacrolimus, in contrast to cyclosporine, has not been found to be associated with gingival enlargement (GE) among adult transplant recipients. The purpose of this study was to explore the prevalence of GE in relation to tacrolimus and cyclosporine-based immunosuppressive regimens among pediatric solid-organ transplant recipients, controlling for the use of calcium channel blockers (CCB) and the presence of supragingival plaque., Methods: A standardized questionnaire was administered and a comprehensive oral examination was performed among pediatric renal and liver transplant recipients who were at least 6 months post-transplant., Results: The prevalence of GE among 133 participants was 26%, with the highest incidence among subjects receiving cyclosporine and CCB (60%) and the lowest among those receiving tacrolimus without CCB (13%). A multivariate model showed that the odds of having GE were 5 times higher among children receiving cyclosporine than in those not receiving this medication, and 4 times higher among boys than girls. Supragingival plaque and the use of CCB, however, were not found to be associated with GE., Conclusion: This study revealed that tacrolimus was not associated with gingival enlargement while cyclosporine remains a risk factor for the development of this condition in pediatric renal and liver transplant recipients.

Objective: To explore the type and prevalence of oral mucosal lesions among adults with primary HIV infection (PHI) compared with HIV-negative adults at high risk for HIV disease, and in relation to HIV viral load., Methods: We conducted standardized oral examinations to identify specific oral mucosal lesions among adults with PHI, both pre-seroconversion and post- seroconversion-recently infected, compared with HIV-negative adults. We compared the group with oral lesions to those without oral lesions with respect to HIV-RNA load and CD4 + T-cell count., Results: Among 115 adults (predominantly men), pseudomembranous candidiasis was the most common oral lesion among those with PHI, and was found in 4% of the 23 participants in pre-seroconversion and in 9% of 69 participants with post-seroconversion recent infection, compared with none found among 23 HIV negatives. Among those with PHI, the median viral load was higher and the median CD4 + T-cell count lower among the 15 participants with an oral lesion of any type than among the 77 participants without oral lesions (P = 0.02 and 0.04, respectively)., Conclusion: This finding suggests that individuals with PHI who have oral lesions may be more likely to transmit HIV because of their higher viral load.

Objectives: This study sought to identify predictors of dental care use in HIV-infected women., Methods: In a cross-sectional survey of HIV-infected women enrolled in the northern California site of the Women's Interagency HIV Study, dental care use and unmet need were assessed in relation to selected variables., Results: Among 213 respondents, who were predominantly Black and younger than 45 years, 43% had not seen a dentist and 53% (among dentate women) reported no dental cleaning in more than a year (although 67% had dental insurance coverage, mainly state Medicaid). Nine percent were edentulous. Among nonusers of dental care, 78% reported that they wanted care but failed to get it. Barriers included fear of and discomfort with dentists, not getting around to making an appointment, and not knowing which dentist to visit. Multivariate analysis showed that lack of past-year dental care was associated mainly with unemployment, a perception of poor oral health, and edentulism., Conclusions: HIV-positive women appear to be underusing dental care services. Fear and lack of information regarding available resources, in addition to unemployment and perception of poor oral health, may be important barriers.

The goals of this study were to compare the prevalence of oral lesions in women infected with human immunodeficiency virus (HIV) and HIV-negative women, and to determine the association of oral lesions with route of HIV transmission and with level of immunosuppression in infected women. As part of a prospective 4-year study, oral examinations and blood tests were performed, at 6-month intervals, on 176 HIV-infected women and on 117 HIV-negative women at risk for HIV infection. We evaluated participants for the following oral conditions: hairy leukoplakia, candidiasis, ulcers, warts, non-Hodgkin's lymphoma, Kaposi's sarcoma, and parotid enlargement. As previously reported in men, the prevalence of oral lesions was significantly higher among HIV-infected (22%) than HIV-negative women (3%) [odds ratio (OR) = 8.2; 95% confidence interval (CI) 2.8, 23.5], particularly candidiasis (14%) and hairy leukoplakia (10%). Among HIV-infected women with CD4 cell count nadir > or = 200 cells/microliters, the prevalence of hairy leukoplakia was higher among those infected heterosexually than among injection drug users (OR = 5.5; 95% CI: 1.5; 19). The OR for the association between oral lesions and CD4 cell count nadir (< 200 vs. > 500 cells/microliters) was 8.9 (95% CI: 2.6, 30), indicating a strong positive association with level of immunosuppression.
