Press Release Date: April 24, 2001
Use of the antifungal medication fluconazole may help prevent the development of oral candidiasis, a common infection of the mucous membranes of the mouth also known as "thrush," in patients with HIV or AIDS, according to a report summary released today by the Agency for Healthcare Research and Quality (AHRQ). The publication summarizes a report, developed by AHRQ's Evidence-based Practice Center (EPC) at the Research Triangle Institute-University of North Carolina at Chapel Hill, that focused on several aspects of the dental management of persons in the United States infected with HIV or living with AIDS.
The researchers found that fluconazole was effective in reducing or preventing recurrences or new
infections of oral candidiasis over a range of 3 to 17 months. While the evidence appears to support the use of fluconazole, itraconazole, ketoconazole, nystatin, and clotrimazole for treating oral candidiasis once it is established, only fluconazole has been shown to be successful at preventing oral candidiasis.
The study also looked at two other aspects of dental management of people with HIV/AIDS: Complications of invasive oral procedures, and the use of oral conditions as markers or indicators of changes in health status. The researchers found very limited evidence on the risks of invasive oral procedures, concluding from four small
studies that tooth extractions appear to result in few postoperative complications among persons living with HIV/AIDS. The complications that did occur were minor and treatable on an outpatient basis.
There was inadequate evidence to assess whether any of several oral conditions are usable as markers to indicate when a person converts from HIV negative to HIV positive. However, there is evidence that two oral conditions—oral candidiasis and Kaposi's sarcoma of the mouth—may be reasonable indicators that an HIV positive person has progressed to a state of severe immune suppression. The evidence suggests that two other oral conditions—oral ulcers and hairy leukoplakia— are not reasonable indicators of severe immune decline in persons who are HIV positive.
The systematic review and analysis of the evidence for these critical oral health care issues was supported through a collaborative effort between AHRQ and the National Institute of Dental and Craniofacial Research of the National Institutes of Health.
