Orofacial manifestations in Brazilian people living with HIV/AIDS under long-term antiretroviral therapy: a cross-sectional study.

OBJECTIVE: The aim of this study was to assess the prevalence of orofacial manifestations in a Brazilian cohort of people living with HIV/AIDS (PLWHIV) using long-term combined antiretroviral therapy (cART) and to correlate the presence of these manifestations with clinical and laboratory characteristics. STUDY DESIGN: A cross-sectional observational study evaluated 101 Brazilian PLWHIV. Demographic characteristics, medical history, and laboratory data were collected. Physical examination and measurement of stimulated salivary flow were performed. RESULTS: The study included 101 participants who were mainly male (61%) and White (73%), with an average age of 48 years, using long-term cART. The most common oral manifestations were facial lipoatrophy (33%), xerostomia (30%), and salivary gland enlargement (12%). Facial lipoatrophy was linked to a longer duration of cART use (P = .002), whereas hairy leukoplakia was linked to a detectable viral load (P = .031). The salivary flow of <0.7 mL/min was associated with an HIV infection time >20 years (P = .023). CONCLUSIONS: People living with HIV/AIDS who use cART often experience facial lipoatrophy, xerostomia, and bilateral enlargement of the parotid glands. Although opportunistic infections and malignant neoplasms are not frequent occurrences, they can still arise.

Clinical outcome of dental procedures among renal transplant recipients.

AIMS: To compare outcomes of dental procedures among a group of renal transplant recipients who had received antibiotic prophylaxis (AP) before the procedure and another group that had not received AP. METHODS AND RESULTS: The records of all renal transplant patients treated at the Special Care Dentistry Center (SCDC) were assessed. Dental procedures documented in the records were classified as invasive or noninvasive. All dental procedures performed were compiled, and the prescription or nonprescription of prophylactic antibiotics, and the incidence and description of postoperative complications after invasive procedures were recorded. Eighty-seven records were evaluated. Out of 190 invasive procedures all were simple dental extractions, 107 (56.3%) were preceded by AP; out of 242 noninvasive procedures, 14 (5.7%) were preceded by AP. A lack of uniformity on the type and dose of the antibiotic prescribed was observed. Four postoperative complications after invasive procedures (dental extraction) were noted and in 2 cases the procedures were preceded by AP. CONCLUSION: This retrospective study showed no difference in postextraction outcomes between renal transplant recipients who received and who did not receive AP before dental extractions.
