Accuracy of diagnoses of HIV-related oral lesions by medical clinicians. Findings from the Women's Interagency HIV Study.

OBJECTIVE: To determine if medical clinicians are as accurate as dental clinicians in recognizing diagnostic characteristics of HIV-related oral lesions. METHODS: In 355 HIV-infected participants at five Women's Interagency HIV Study sites, we paired oral examinations conducted within 7 days of each other by dental and medical clinicians. We used the former as a gold standard against which to evaluate the accuracy of the latter. We assessed the accuracy of the medical clinicians' findings based both on their observations of abnormalities and on their descriptions of these abnormalities. RESULTS: Dental clinicians diagnosed some oral abnormality in 38% of participants. When "abnormality" was used as the medical clinicians' outcome, sensitivities were 75% for pseudomembranous candidiasis and 58% for erythematous candidiasis, but only 40% for hairy leukoplakia. When a precise description of the abnormality was used as their outcome, sensitivities were 19%, 12% and 20%, respectively. CONCLUSIONS: Medical clinicians recognize that HIV-related oral abnormalities are present in 40-75% of cases, but less often describe them accurately. Low sensitivity implies that the true associations of specific oral lesions with other HIV phenomena, such as time until AIDS, must be stronger than the literature suggests.

Seroprevalence of HTLV-I and HTLV-II among a cohort of HIV-infected women and women at risk for HIV infection. Women's Interagency HIV Study.

OBJECTIVES: To determine the seroprevalence of, and risk factors for, HTLV-I and HTLV-II infection among HIV-infected women and women at high risk for HIV infection. DESIGN: Cross-sectional analysis of baseline data for women enrolled in the prospective Women's Interagency HIV Study (WIHS). METHODS: From October 1994 through November 1995, 2657 women from five metropolitan areas in the United States (Chicago, Los Angeles, New York City [two sites], Northern California, and Washington DC) were enrolled in WIHS. An interview-based survey collected data on demographics, behavior, and medical history. HTLV-I and HTLV-II determinations were made using a combined HTLV-I/HTLV-II indirect immunofluorescent antibody (IFA) screening test, an IFA titration specificity test, and individual HTLV-I and HTLV-II confirmatory Western blots. Fisher's exact tests and logistic regression were used to determine univariate and multivariate independent predictors for HTLV-II infection. RESULTS: Of 2625 women enrolled in WIHS with confirmed HIV results, 2487 (95%) were tested for HTLV-I and HTLV-II. Of these, 241 (10%) were HTLV-II-seropositive and 13 (0.5%) were HTLV-I-seropositive. On multivariate analysis, independent predictors of HTLV-II infection included injection drug use (OR = 5.2; p < .001), black race (OR = 3.6; p < 0.001), age >35 years (OR = 3.3; p < .001) and a history of sex with a male injecting drug user (OR = 1.9; p < .001). Among women infected with HIV, the seroprevalence of HTLV-II was 11% compared with 6% for women at risk for HIV but not infected (p < .001). However, HIV was not an independent predictor of HTLV-II infection in multivariate analysis. CONCLUSIONS: This cross-sectional analysis confirms that HTLV-II is found commonly in HIV-infected women and uninfected women at risk for HIV in major urban areas throughout the United States and that HTLV-II is far more common than HTLV-I in these populations. Although injecting drug use is most strongly associated with HTLV-II infection, sexual transmission likely contributes to the high HTLV-II seroprevalence in this cohort.

HIV-1-associated Kaposi's sarcoma in a predominantly black population at an inner city hospital.

BACKGROUND: Kaposi's sarcoma (KS) associated with human immunodeficiency virus type 1 (HIV-1) is the most common malignancy in patients with AIDS. It has been most commonly reported in white homosexual men, though a few cases have been reported in blacks. METHODS: We conducted a retrospective analysis of all HIV-1 seropositive patients with biopsy-proven KS seen at Howard University Hospital between February 1985 and June 1995. RESULTS: Of the 73 patients identified, 66 (90%), 4 were white, 2 were Hispanic, and 1 was of unidentified race. The median age was 32 years. Forty-eight (66%) were homosexual or bisexual men, and 10 (14%) were homosexual or bisexual with a history of intravenous drug use (IDU). A history of IDU or blood transfusion was the only risk factor in 7 (9%) and 2 (3%), respectively. The other 6 (8)% were heterosexual. The median survival was 2.2 years. A CD4 count <200 and the presence of an opportunistic infection were associated with shortened survival. CONCLUSIONS: The predominant risk factor for HIV-1-associated KS was homosexual or bisexual activity. Only a few women with KS were identified, and they also reported sexual transmission from male bisexuals and/or drug users. Poor survival was associated with CD4 <200, stage III and IV KS at presentation, and opportunistic infections.
