US1 HIV – changing patterns in HAART era, patients’ quality of life and occupational risks

Abstract

Oral manifestations are early and important indicators of HIV‐infection. Several lesions with strong association to HIV infection have been described: oral candidiasis (OC), oral hairy leukoplakia (OHL), Kaposi's sarcoma (KS), Non‐Hodgkin‐Lymphoma (NHL), necrotising ulcerative gingivitis and periodontitis. These lesions may be present in up to 50% of patients with HIV‐infection and up to 80% of those with AIDS. Changing patterns in HAART era: With the advent of highly active antiretroviral therapy (HAART) the prevalence of OC, OHL and HIV – associated periodontal disease has decreased in adults. The prevalence of KS has not changed. However, there has been an increase in HPV‐associated oral lesions (papillomas, condylomas and focal epithelial hyperplasia) and HIV‐related salivary gland disease. In children receiving HAART no change in the prevalence of HIV‐related oral lesions has been found. Quality of life: The presence of oral lesions has a marked impact on health related quality of life. HIV‐associated orofacial lesions may lead to facial disfigurement (KS, NHL) or may impair speech and swallowing. Consequently, weight loss and pain may be result. Studies have shown that patients with OC, angular cheilitis and OHL have a high score of decayed teeth (DMFT). Xerostomia and taste disturbances may also be factors with impact on quality of life. Occupational risks: Occupational exposure to HIV has resulted in 57 documented cases of HIV sero‐conversion among healthcare workers in the US (December 2001). Exposure to HBV and HCV carries a much higher risk of occupational infection than that for HIV‐exposure.
