HHV-8 DNA replication correlates with the clinical status in AIDS-related Kaposi’s sarcoma
چکیده انگلیسی


• HHV-8 DNA detection in plasma is strongly associated with active KS disease.
• HHV-8 DNAaemia is strongly and independently correlated with both clinical status and HIV-1 plasma viraemia.
• These findings are compatible with an active role of replicating virus in clinically active AIDS-KS.

BackgroundThe value of plasma levels of human herpesvirus 8 (HHV-8) DNA as a marker of clinical status in acquired immunodeficiency syndrome-related Kaposi’s sarcoma (AIDS-KS) remains to be elucidated.ObjectivesTo investigate the relationship between the plasma HHV-8 DNA viral load and the clinical status of AIDS-KS.Study DesignA total of 378 blood samples were obtained from 62 patients with AIDS-KS followed longitudinally. All patients received antiretroviral therapy (ART) or anti-neoplastic therapy. The patients were divided into four groups according to their clinical status: onset disease (OD), progressive disease (PD), stable or partial remission (S/PR) and complete remission (CR).ResultsPlasma HHV-8 DNAaemia was detected in all samples obtained from patients with OD or PD (100%); in contrast, HHV-8 DNAaemia was found only in a minority of patients with CR (8%) and was invariably undetectable in patients with stable CR. HHV-8 DNA detection in plasma was strongly associated with an unfavourable outcome (odds ratio = 231.9; p < 0.0001). Conversely, neither the HIV-1 viral load nor peripheral CD4+ T-cell counts were associated with the KS clinical status, though both parameters did affect HHV-8 DNAaemia levels (p < 0.0001). Multivariate analysis confirmed that HHV-8 DNAaemia was strongly and independently correlated with both clinical status (p < 0.05) and HIV-1 plasma viraemia (p = 0.027).ConclusionsThe strong association of plasma HHV-8 DNAaemia with onset or progressive disease is compatible with an active role of replicating virus in clinically active AIDS-KS. An accurate evaluation of the plasma HHV-8 load might be useful for monitoring AIDS-KS under antiretroviral or antineoplastic therapy.
