ABSTRACT
BACKGROUND:
Kaposi's sarcoma-associated herpesvirus (KSHV) seropositivity and lytic antibody titer are predictors for Kaposi's sarcoma.METHODS:
We examined demographic, viral, and immunologic factors that influence KSHV latent and lytic antibodies in HIV-infected patients.RESULTS:
Detection rate of KSHV latent but not lytic antibodies was lower in patients with CD4 cells/mm3 less than 200 than greater than 200 (odds ratio [OR], 0.26; 95% confidence interval [CI], 0.11-0.61) and CD8 cells/mm3 less than 400 than greater than 400 (OR, 0.26; 95% CI, 0.07-0.67). Overall seropositivity rate was higher in patients with CD4 cells/mm3 less than 200 than greater than 200 (OR, 2.34; 95% CI, 1.37-4.02) and HIV copies/mL greater than 400 than less than 400 (OR, 1.70; 95% CI, 1.09-2.65). Lytic antibody level was inversely correlated with CD4 count (P < 0.001). Lytic seropositivity (OR, 2.47; 95% CI, 1.35-4.50) and antibody level (adjusted difference mean optical density, 0.324; 95% CI, 0.16-0.46) were higher in patients with HIV infection greater than 15 than less than 15 years. Hispanics had higher lytic seropositivity rate (OR, 1.71; 95% CI, 1.07-2.73) and antibody level (adjusted difference mean optical density, 0.111; 95% CI, 0.03-0.18) than non-Hispanics.CONCLUSIONS:
Lower CD4 and CD8 counts impair antibody response to KSHV latent antigens. Immune deterioration, long-term HIV infection, and Hispanic status are risk factors for Kaposi's sarcoma predictors.
