Detection of Herpesvirus-Like DNA Sequences in Kaposi's Sarcoma in Patients with and Those without HIV Infection
Open accessAbstract
BACKGROUND: Herpesvirus-like DNA sequences have recently been found in lesions from patients with Kaposi's sarcoma and the acquired immunodeficiency syndrome (AIDS). It is not known whether these sequences are also present in classic Kaposi's sarcoma or in the Kaposi's sarcoma that occurs in homosexual men who are seronegative for the human immunodeficiency virus (HIV). METHODS: We analyzed DNA in tissue samples from patients with AIDS-associated Kaposi's sarcoma, patients with classic Kaposi's sarcoma, and HIV-seronegative homosexual men with Kaposi's sarcoma. We also analyzed DNA in samples of uninvolved tissue from these patients and in control tissue from healthy subjects. All samples were tested blindly by polymerase chain reaction (PCR) with specific primers to amplify KS330(233), a herpesvirus-like DNA sequence. RESULTS: The KS330(233) PCR product was found in 20 of 21 tissue samples (95 percent) from the patients with Kaposi's sarcoma, including 10 of the 11 samples from the patients with AIDS-associated Kaposi's sarcoma, all 6 samples from the patients with classic Kaposi's sarcoma, and all 4 samples from the HIV-negative homosexual men with Kaposi's sarcoma. Only 1 of the 21 control samples (5 percent) was positive (odds ratio, 400; 95 percent confidence interval, 19 to 17,300). Of the 14 samples of uninvolved skin from the patients with Kaposi's sarcoma, 3 were positive for KS330(233). Representative PCR-product sequences were more than 98 percent identical for the three types of Kaposi's sarcoma, suggesting that all three are caused by the same agent. CONCLUSIONS: The same herpesvirus-like DNA sequences are present in AIDS-associated Kaposi's sarcoma, classic Kaposi's sarcoma, and the Kaposi's sarcoma that occurs in HIV-negative homosexual men. Therefore, this presumably new human herpesvirus is not solely an opportunistic infection in patients with AIDS, and the three forms of Kaposi's sarcoma may be caused by the same infectious agent.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
