title: Oral and constitutional manifestations of HIV-infected hospital patients in Northern Vietnam.
abstract: This study reports clinical features, with emphasis on oral lesions and constitutional signs, of 170 patients in a regional hospital in northern Vietnam, of whom 56 were HIV positive. The purpose of the study was to investigate the relationship of oral hairy leukoplakia (OHL) and oropharyngeal candidiasis (OPC) with HIV infection and late stage HIV disease. Late stage HIV disease was defined as WHO stage III or IV and/or a total lymphocyte count below 1200 cells/mm3. The 56 HIV positive patients included all patients with a positive HIV test between July 7th and September 9th 2002. A total of 114 HIV negative controls were included as well. All patients had a detailed medical history and examination as well as a thorough oral examination, which were all done without prior knowledge of the patient's HIV serostatus. HIV positive patients were then grouped according to WHO clinical stage and total lymphocyte count. Thirty-six patients (64.3%) out of 56 HIV positives were in WHO stage III+IV and 28 patients (50.0%) had a total lymphocyte count below 1200 cells/mm3. The presence of OPC, weight loss of more than 10% of body weight and/or chronic fever of more than one month's duration showed a significant association and high positive prediction with HIV infection, especially late stage HIV disease [all with odds ratio (OR) and 95% confidence interval (CI > 1)]. The presence of OHL only showed a significant association with positive HIV serostatus and WHO stage III+IV. It can be concluded that in North Vietnam, HIV positive patients and patients suspected of having HIV infection would benefit from initial and repeat oral examinations. OPC, together with other signs of progressive infection (constitutional signs, such as weight loss and chronic fever) may serve as indicators for institution of prophylactic drugs against opportunistic infections and even antiretroviral (ARV) therapy, when available. However, further research is needed to demonstrate the role of OHL in HIV patients in North Vietnam.
