- Abstract
Human herpesvirus type 8 (HHV-8) DNA is consistently found in all types of Kaposi's sarcoma, which is prevalent in immunocompromised patients. Patients with advanced lung carcinoma often showed immunologic abnormalities, and prevalence of HHV-8 infection is unclear. In this study, blood samples from 109 lung carcinoma patients and 109 age- and sex-matched healthy controls were analyzed for lymphocyte and monocyte counts, and for antibody, DNA, and genotype of HHV-8. Lung carcinoma patients had significantly lower lymphocyte and higher monocyte counts than healthy controls ( p < 0.0001, both). HHV-8 seropositivity was more prevalent in lung carcinoma patients (41.3 %), particularly in male patients (50.8 %), than in controls (24.8 %) ( p = 0.01 and 0.002, respectively). The seropositivity was also significantly higher in male (50.8 %) than female patients (27.3 %, p = 0.01). Titers of HHV-8 antibody in patients also significantly exceeded those in controls ( p = 0.004). Under a higher threshold (antibody titer ≥1:160) which is equivalent to that of enzyme-linked immunosorbent assay, lung carcinoma patients still had higher HHV-8 seropositivity than controls ( p = 0.006). Three patients with stage IV lung carcinoma were positive for HHV-8 DNA with K1 gene subtype C3, D1, and E, respectively; they had much lower lymphocyte counts (658 ± 132 µL) than patients positive for HHV-8 antibodies only (1,449 ± 873 µL). The study indicates that lung carcinoma patients, particularly males, have a high seroprevalence of HHV-8. HHV-8 DNA detected in the patients with advanced lung carcinoma may be a result of virus reactivation in the immunocompromised status.
