Description:Background:
HIV infection is associated with increased susceptibility to common pathogens which may trigger chronic antigenic stimulation and hyperactivation of B-cells, events known to precede the development of AIDS-associated non-Hodgkin lymphoma (AIDS-NHL).
Methods:
To explore whether cumulative exposure to infectious agents contributes to AIDS-NHL risk, we tested sera from 199 AIDS-NHL patients (pre-NHL, average lead-time 3.9 years) and 199 matched HIV-infected controls from the Multicenter AIDS Cohort Study (MACS), for anti-IgG responses to 18 pathogens using multiplex serology. Odds ratios and 95% confidence intervals were estimated using conditional logistic regression models.
Results:
We found no association between cumulative exposure to infectious agents and AIDS-NHL risk (OR 1.01, 95% CI 0.91–1.12). However, seropositivity for trichodysplasia spinulosa polyomavirus (TSPyV), defined as presence of antibodies to TSPyV capsid protein VP1, was significantly associated with a 1.6-fold increase in AIDS-NHL risk (OR 1.62, 95% CI 1.02–2.57). High Epstein-Barr virus (EBV) anti-VCA p18 antibody levels closer to the time of AIDS-NHL diagnosis (<4 years) were associated with a 2.6-fold increase in AIDS-NHL risk (OR 2.59, 95% CI 1.17–5.74). Additionally, high EBV anti-EBNA-1 and anti-ZEBRA antibody levels were associated with 2.1-fold (OR 0.47, 95% CI 0.26–0.85) and 1.6-fold (OR 0.57, 95% CI 0.35–0.93) decreased risk for AIDS-NHL, respectively.
Conclusions:
Our results do not support the hypothesis that cumulative exposure to infectious agents contributes to AIDS-NHL development. However, the observed associations with respect to TSPyV seropositivity and EBV antigen antibody levels offer additional insights into the pathogenesis of AIDS-NHL.
